Technology is in the way to reach in its climax but the basic understanding of science in many phenomena is still awaited even though the nature witnesses it. Scientific research reveals strong analogy between photon and electron. When an atom deals neutral state, it levitates electron of outer ring from the back surface while placing the bit-energy at front surface. Gravitation behavior of that electron starts at the centre of relaxation point by including the force of side pole where the pulling force of nearby unfilled state of that atom from the front surface results into depict forcing energy shape like Gaussian distribution symbol with both ends turned called unit photon. The inertia is being involved at each stage of changing direction of that electron by introducing the disappearances of forces of two poles against the appearances of forces of two opposite poles during rest to motion and motion to rest in the first half-cycle. The same is the case in the second half-cycle of that electron during rest to motion and motion to rest but it is under different introduction of the disappearances of forces against appearances of forces. However, at stage of levitating or gravitating period of electron, only one force is being involved at one time where the opposite force is disappeared. The uninterrupted confined inter-state electron-dynamics of atom under the availability of several bits of bit-energy results into generate forcing energy shape like a wave. Two bits of bit-energy where shape of bit for first half-cycle is like integral symbol and second half-cycle is like opposite integral symbol which are being placed along the configuring trajectory of inter-state electron-dynamics during forward-direction cycle and two bits of bit-energy shape in opposite order are being placed along the trajectory of inter-state electron-dynamics during back-direction cycle. Generating forcing energy of unit photon in each cycle is pushing to the rear side by remaining connected till the electron is not restoring the state of rest. Silicon atom is considered as a model system under neutral state. Uninterrupted confined inter-state electron-dynamics result into generate forcing energy that can travel immeasurable length and unavailability of necessitating bit-energy at any interrupted stage result into generate an overt photon. Inter-state electron-dynamics for at least two cycles generate an overt photon –a photon length twice to unit photon. Under certain interaction of unit photon, it divides equally into two bits of bit-energy instead of dividing into tits and bits of heat. The mechanism of generating photon characteristic current by the electron of neutral state atom validates that atoms are four-dimensional discs at centre of dealing no force. An isolated electron is being grounded under directed forcing energy to impinge a neutral state atom where the gained instantaneous velocity under merged energy resulting into distort atom at that point. Matter changes the role of energy and force under various sorts of interactions. Here, heat energy and photon energy explore matter at atomic and electron levels, thus, devise basis of science to describe.

Technology is in the way to reach in its climax but the basic understanding of science in many phenomena is still awaited despite the fact that nature justifies all those. Scientific research reveals strong analogy between electron and photon. Atoms that execute suitable electronic transitions, on absorbing heat energy at shunt level, excite their electrons. De-excitation of an electron under the gravitational force of its nucleus, where inertia is involved, results into depicting energy in the shape like Gaussian distribution. The wavelength of photon remains in inter-state electron’s gap where the source of generating energy in wave-like fashion is due to confined electron-dynamics of that atom eligible to execute electronic transition; energy configures under electron’s trajectory while excitation period is due to inertia-levitation-inertia behaviours and energy configures under electron’s trajectory while de-excitation period is due to inertia-gravitation-inertia behaviours. Silicon atom is a model system of it. Uninterrupted confined inter-state electron’s motion results into configure force energy that can travel immeasurable length where interruption from the point of generation termed it a photon. Such photons increase wavelength under decreasing energy. Here, I discuss that heat energy is due to merged photons or squeezed photons and photonic current is due to the configuring energy in inter-state electron’s gap under confined electron-dynamics of the atom. Force of repulsion or attraction in certain materials engages the phenomenon of levitism or gravitism where inertia is exempted. Structural motifs and dynamics are subjected to characteristic photons as long as atoms are dealing neutral behavior of field forces. A structural design delivers straight-forward application on dealing photons of certain wavelengths. Here, heat energy and photon energy explore matter at electron level. Thus, devise science to describe.

Many studies deal synthesis of carbon materials including all the disclosed states. This study describes the binding mechanism of different state carbon atoms. The binding energy as per gauge of certain state carbon atom is being invited under the application of force. In evolving different structures of carbon atoms their admissible electron-dynamics generate binding energy. Evolution of graphite structure is one-dimensional when certain amalgamated atom executes electron-dynamics to gain stable state to bind atom of attained stable state. Evolution of graphite structure is two-dimensional when amalgamated atoms under attained dynamics deal difference in surface format forces at the point of binding. Structural evolution is two-dimensional for nanotube and four-dimensional for fullerene (bucky balls). Structure evolution of graphite, nanotube and fullerene involve surface format forces mainly to invite binding energy of their atoms as per gauge of electron-dynamics. Structural evolutions of diamond and Lonsdaleite are under the joint application of surface format forces and grounded format forces to invite binding energy of atoms. Structural evolution of graphene involves both surface and space format forces to invite binding energy of atoms. Glassy carbon is related to layered wholly topological structure where layers of gas state carbon atoms, graphitic state and lonsdaleite state are being involved in successive manner to invite binding energy under space, surface and grounded format forces. Due to maintenance of electrons, carbon atoms do not bind when in the gas state. Diamond is south to ground tetra-dimensional, Lonsdaleite is south to ground bi-dimensional and graphene is ground to north tetra-dimensional topological structures. The Mohs hardness of carbon-based materials under different levitation gravitation behaviors attempting at electron level under contraction expansion of clamping energy knot is sketched. Carbon atoms when in fullerene structure is the best model to understand the influencing force at ground surface and the best model to explain binding mechanism in atoms of other elements.

Technology has nearly reached to its climax but the basic understanding of science in many phenomena is still awaited. Scientific research reveals strong analogy between electron and photon. Atoms that execute suitable electronic transitions, on absorbing heat energy at shunt level, excite their electrons. De-excitation of an electron, where inertia is involved, results depicting energy in the shape-like Gaussian distribution. The wavelength of photon at point of generation remains in inter-state electron’s gap distance and atoms of all those suitable elements that glitter perform like magician, throwing one and catching other, where an electron excites at shunt level of energy and configure trajectory under inertia-levity-inertia and de-excites at free fall configuring trajectory under inertia-gravity-inertia and silicon atom is a model system. In such atoms, heat energy of merged photons is cultivated and that shunt energy perturb the balance of inherent energy between electron and nucleus while balancing it via another electronic transition in reverse mode of the same atom. Uninterrupted confined inter-state electron-dynamics results into wave that can travel immeasurable length and on breaking inter-state electron-dynamics results into fixed length discrete energy wave called a photon. Such photons increase wavelength on decreasing frequency, propagate to hard X-ray, to visible spectrum, and to beyond. Here, I discuss that heat energy is due to merged photons, photons characteristic current are due to photons having wavelength in inter-state electron’s gap distance and light is due to photons having wavelength in visible spectrum. Force of repulsion or attraction in certain materials engages the phenomenon of levitism or gravitism instead of magnetism where inertia is no longer prevailed. All structural motifs and dynamics are subjected to characteristic photons as long as bearing the neutral behavior of the external forces. A structural design delivers straight-forward application on coordinating different energy shaped photons. The various gadgets, devices and instruments only operate energy as per need of necessity. Here, materials science explores matter to sub-atomic level while coordinating and interacting energy and devises science to describe.

Inorganic nanoparticle-filled polymer composites have extended their multiple functionalities to various applications, including cultural heritage conservation. Therefore, this study has examined the effects of clay, SiO2, Ca(OH)2 and CaCO3 nanomaterials in the enhancement of the physicomechanical properties of limestone monuments, the aim of the present work being to evaluate comparatively the effectiveness of nanoparticles as consolidation and protection material for limestone artworks. The nanoparticles were added to an acrylic-based copolymer (polyethylmethacrylate (EMA)/methylacrylate (MA) (70/30), in order to improve its physiochemical and mechanical properties, and produced a significant improvement in the ability of the polymers to consolidate and protect the stone. The synthesis process of nanoparticles/polymer nanocomposite has been prepared by an in situ emulsion polymerization system. The nanocomposites contained poly (EMA/MA) with a solid content of 3% [poly (EMA/MA)] in the absence and presence of 5% nanoparticles (0.15 g nanoparticles). Samples were subjected to artificial aging by relative humidity/temperature and acid/salt crystallization weathering to show the optimum conditions of durability and the effectiveness of the nano-mixture in improving the physical and mechanical properties of the stone material. To ensure that the treatment had no negative effects on the physical characteristics of the limestone, the properties of the treated limestone samples were evaluated comparatively before and after artificial aging by the conduct of microstructural (phase morphology studied by means of scanning electron microscopy) and aesthetic (colour and lightness measured by spectrophotometry) analyses. Also used were measurement of static contact angle of water droplets on the surface of the samples, total immersion water absorption, compressive strength, and abrasion resistance test. Results demonstrated that the addition of nanoparticles to an acrylic-based polymer enhanced its capability to consolidate and protect the limestone samples.

This paper describes a new approach that can be used to determine the mechanical properties of unknown materials and complex material systems. The approach uses inverse finite element modelling (FEM) accompanied with a designed algorithm to obtain the modulus of elasticity, yield stress and strain hardening material constants of an isotropic hardening material model, as well as the material constants of the Drucker-Prager material model (modulus of elasticity, cap yield stress and angle of friction). The algorithm automatically feeds the input material properties data to finite element software and automatically runs simulations to establish a convergence between the numerical loading-unloading curve and the target data obtained from continuous indentation tests using common indenter geometries. A further module was developed to optimise convergence using an inverse FEM analysis interfaced with a non-linear MATLAB algorithm. A sensitivity analysis determined that the dual Spherical and Berkovich (S&B) approach delivered better results than other dual indentation methods such as Berkovich and Vickers (B&V) and Vickers and Spherical (V&S). It was found that better convergence values can be achieved despite a large variation in the starting parameter values and / or material constitutive model and such behaviour reflects the uniqueness of the dual S&B indentation in predicting complex material systems. The study has shown that a robust optimization method based on a non-linear least-squares curve fitting function (LSQNONLIN) within MATLAB and ABAQUS can be used to accurately predict a unique set of elastic plastic material properties and Drucker-Prager material properties. This is of benefit to the scientific investigation of properties of new materials or obtaining the material properties at different location of a part which might be not be similar due to manufacturing processes (e.g. different heating and cooling rates at different locations).

Misconception in using terms photon and electron exists in science. When the electron of outer ring in silicon atom executes interstate dynamics for only one cycle, it generates force and energy for the unit photon. Interstate dynamics of the electron for one forward and reverse cycle generate the overt photon having the least measured length. When the photon of suitable length interacts with the side of laterally orientated electron of an atom, it converts into the heat energy. Under the approximate angle of 90º, when a photon interacts with the tip of laterally orientated electron, it divides into the bits of energy having a shape like integral symbols. In the neutral state silicon atom, the centre acts as the reference point for electrons executing interstate dynamics and the lateral lengths of the electrons remains along the north-south poles. Under the availability of energy and force, the energy wraps around the force shaping along the tracing trajectory of electron dynamics in a silicon atom. A force is being shaped from the sides of electron not experiencing the exertions of forces. In interstate dynamics, electron of the outer ring first reaches the ‘maximum limit point’, where energy of one bit is utilized wrapping around the shaping force along its tracing trajectory. From the ‘maximum limit point’, electron completes the second half cycle dealing with relevant forces, where again energy of one bit is wrapped around the shaping force along the tracing trajectory. The shape of unit photon is like ‘Gaussian distribution of turned ends’. Under the uninterrupted heat energy for the silicon atom, an electron dynamics generates the photon having a shape like wave. Path independent but interstate dependent forces take over the control of electron. That electron executes dynamics nearly in the speed of light. In confined interstate dynamics, naturally viable conservative forces exert to the position-acquiring electron. A photon can be in the continuous and unending length if the electron dynamics remains uninterrupted. Having not made contact with states limiting the forces at work, the changing aspect of electron recalls auxiliary moment of inertia at each point of turning. By executing electron dynamics, atoms under neutral states generate photons of different shapes, so revealing the phenomena of heat and photon energy.

Technology is in the way to reach in its climax but the basic understanding of science in many phenomena is still awaited despite the fact that nature witnesses. Scientific research reveals strong analogy between electron and photon. Atoms of solid state behavior that execute suitable electron transitions excite electron at target while absorbing heat energy at shunt level. De-excitation of electron under the pulling force of nearby unfilled state available at bare surface of atom results into depicting force energy shape-like Gaussian distribution called unit photon where inertia involved at each stage of changing state. The continuous cycles of excitation and de-excitation of electron confined within inter-state (filled to unfilled and unfilled to filled) result into generate force energy in wave-like fashion propagating in the inter-state electron’s gap of adjacent atoms in the lattice; in each unit photon, the force energy configures under electron’s trajectory while excitation period is due to inertia-levitation-inertia behaviors and force energy configures under electron’s trajectory while de-excitation period is due to inertia-gravitation-inertia behaviors. Silicon atom is considered as a model system of it. Uninterrupted confined inter-state electron-dynamics results into configure force energy that can travel immeasurable length where interruption from the point of generation termed it an overt photon –a long length photon. Such photons increase wavelength under decreasing energy when travelling in the medium other than inter-state electron’s gap where light glow is observed on attaining wavelength of their certain density in the visible range. They act as merged photons or squeezed photons while interacting (coordinating) to suitable medium, thus, on merging or squeezing convert into heat energy where atoms like silicon again configure them into force energy under the trajectory of electrons. Thus, heat energy dealing to suitable matter at atomic level transforms into photon energy. Involving levitation behavior in the course of exciting electron and gravitation behavior in the course of de-exciting electron validates that force of repulsion or attraction in certain materials engages the phenomenon of levitism or gravitism where inertia is exempted. Here, heat energy and photon energy explore matter at electron level. Thus, devise science to describe.

Technology is in the way to reach in its climax but the basic understanding of science in many phenomena is still awaited despite the fact that nature justifies all those. Scientific research reveals strong analogy between electron and photon. Atoms that execute suitable electronic transitions, on absorbing heat energy at shunt level, excite their electrons. De-excitation of an electron under the gravitational force of its nucleus, where inertia is involved, results into depicting energy in the shape like Gaussian distribution. The wavelength of photon remains in inter-state electron’s gap where the source of generating energy in wave-like fashion is due to confined electron-dynamics of that atom eligible to execute electronic transition; energy configures under electron’s trajectory while excitation period is due to inertia-levitation-inertia behaviours and energy configures under electron’s trajectory while de-excitation period is due to inertia-gravitation-inertia behaviours. Silicon atom is a model system of it. Uninterrupted confined inter-state electron’s motion results into configure force energy that can travel immeasurable length where interruption from the point of generation termed it a photon. Such photons increase wavelength under decreasing energy. Here, I discuss that heat energy is due to merged photons or squeezed photons and photonic current is due to the configuring energy in inter-state electron’s gap under confined electron-dynamics of the atom. Force of repulsion or attraction in certain materials engages the phenomenon of levitism or gravitism where inertia is exempted. Structural motifs and dynamics are subjected to characteristic photons as long as atoms are dealing neutral behavior of field forces. A structural design delivers straight-forward application on dealing photons of certain wavelengths. Here, heat energy and photon energy explore matter at electron level. Thus, devise science to describe.

Our investigations show that electrochemical corrosion of copper is faster than electrochemical corrosion of aluminium at temperatures below 100oC. Literature data analysis shows that the Al atoms diffuse faster than the Cu atoms at temperatures higher than 475oC, Al rich intermetallic compounds (IMCs) are formed faster in the Cu-Al system, and the Kirkendall plane shifts toward Al side. Electrochemical corrosion occurs due to electric current and due to diffusion. An electronic devise working time, for example, depends on initial copper cover thickness on aluminium wire, connected to the electronic devise, temperature, and volume and dislocation pipe diffusion coefficients, so copper, iron, and aluminium electrochemical corrosion rates are investigated experimentally at room temperature and at temperature 100oC. Intrinsic diffusivities ratios of copper and aluminium at different temperatures and diffusion activation energies in the Cu-Al system are calculated by proposed here methods using literature experimental data. Dislocation pipe and volume diffusion activation energies of pure iron are calculated separately by earlier proposed method using literature experimental data. Aluminium dissolved into NaCl solution as the Al3+ ions at room temperature and at temperature 100oC, iron dissolved into NaCl solution as the Fe2+ (not Fe3+) ions at room temperature and at temperature 100oC, copper dissolved into NaCl solution as the Cu+ ions at room temperature and as the Cu+ and the Cu2+ ions at temperature 100oC. It is founded experimentally that copper corrosion is higher than aluminium corrosion, and ratio of electrochemical corrosion rates, kCu/kAl>1, decreases with temperature increasing, although iron electrochemical corrosion rate doesn’t depend on temperature below 100oC. It is obvious, because melting point of iron is more higher then melting point of copper or aluminium. It is calculated that copper electrochemical corrosion rate is approximately equal to aluminium electrochemical corrosion at temperature about 300oC, so copper can dissolve into NaCl solution mostly as the Cu2+ ions at temperature about 300oC. Ratio of intrinsic diffusivities, DCu/DAl <1, increases with temperature increasing, and intrinsic diffusivity of aluminium could be approximately equal to intrinsic diffusivity of copper at temperature about 460oC.

Many studies discuss carbon-based materials because of the versatility of the carbon element. They present different sorts of understandings fairly at convincing and compelling levels. A gas-state carbon atom converts into its various states depending on the conditions of processing. The electron transfer mechanism in the gas-state carbon atom is responsible for its conversion to various states, namely, graphite, nanotube, fullerene, diamond, lonsdaleite and graphene. The shape of energy responsible to transfer electron from the sides (east- and west-poles) of its atom is like parabola. That energy is linked to states (from filled state to nearby unfilled state) where exerted force to relevant poles of transferring electron is remained neutral. So, the mechanism of originating different states from a gaseous carbon atom is under the involvement of energy at first, which is not the case for atoms executing their confined inter-state electron-dynamics where force is involved at first. Structure evolved in graphite-, nanotubes- and fullerene-states have respectively one-dimensional, two-dimensional and four-dimensional atoms. Moreover, the associated energy curve is a parabola, indicating the transfer of electrons under neutral exertion of forces to their relevant poles. The graphite structure under only attained-dynamics of atoms is also developed but in two-dimension. Here, binding energy between graphitic carbon atoms is engaged under the influence of a small difference available between their involved forces along opposite poles. Structural evolution in diamond, lonsdaleite and graphene atoms involve potential energy of electrons required to undertake infinitesimal displacements under orientationally-controlled exerting forces to their relevant poles. In this study, the growth of diamond is found to be south to ground where atoms bound ground to south. Thus, diamond atoms merge for a tetra-electron ground to south topological structure. Lonsdaleite atoms merge for a bi-electron ground to just-south topological structure. The growth of graphene was just-north to ground; however, the binding of atoms was ground to just-north showing tetra-electrons ground to just-north topological structure. Glassy carbon exhibits layered-topological structure which successively binds tri-layers of gas-, graphite- and lonsdaleite-state atoms in repetitive manner. Orientating pair of electrons of each atom of below gas layer and above lonsdaleite layer enter from the rear side and front side respectively to undertake another clamping of unfilled energy knots belonging to each atom of intermediate graphitic layer. Different carbon atoms develop amorphous structures when they bind under frustrating amalgamation. Hardness of carbon-based materials was also sketched in the light of force-energy behaviors of different state carbon atoms. Here, structure evolution in each carbon state atom explores its own science.

Many studies discuss carbon-based materials because of the versatility of the carbon element. They present different sorts of understandings fairly at convincing and compelling levels. A gas state carbon atom converts into its various states depending on the conditions of processing. The electron transfer mechanism in the gas state carbon atom is responsible for its conversion to various states namely, graphite, nanotube, fullerene, diamond, lonsdaleite and graphene. The shape of energy responsible to transfer electron from the sides (east- and west-poles) of its atom is like parabola that is linked to states where exerted force to relevant poles of transferring electron (from filled state to nearby unfilled state) is remained neutral. So, the mechanism of forming different states of a gaseous carbon atom is under a bit non-conserved involving energy, which is not the case for atoms executing their confined inter-state electron-dynamics. Structure evolved in graphite, nanotube and fullerene states have one-dimensional, two-dimensional and four-dimensional atoms, respectively, and the associated energy curve is like parabola indicating transfer of electrons under neutral exertion of forces to their relevant poles. The graphite structure under only attained-dynamics of atoms is also developed but in two-dimension where engaged binding energy between them is under an influence of a small difference between involved forces of their opposite poles. Structural evolution in diamond, lonsdaleite and graphene atoms involve potential energy of electrons required to undertake infinitesimal displacements under orientationally-controlled exerting forces to their relevant poles. In this study, the growth of diamond was found to be from south to ground in which the atoms were bound in ground to south indicating tetra-electrons ground to south topological structure. Lonsdaleite showed a bi-electrons ground to just-south topological structure. The growth of graphene was just-north to ground; however, the binding of atoms was ground to just-north showing tetra-electrons ground to just-north topological structure. Glassy carbon exhibits layered-topological structure which successively binds tri-layers of gas, graphite and lonsdaleite state atoms in the repetitive manner. In this case, pair of orientated electrons of gas atoms and lonsdaleite atoms in their layers take another clamping of pair of unfilled energy knots by entering from the rear-side and front-side, respectively and to bind to intermediate layers of graphitic carbon atoms. Different carbon atoms develop amorphous structures when they bind under frustrating amalgamation. Hardness of carbon-based materials was also sketched in the light of different force-energy behaviors of different state carbon atoms. Here, structure evolution in each carbon state atom explores its own science.

Technology is in the way to reach in its climax but the basic understanding of science in many phenomena is still awaited even though the nature witnesses it. Scientific research reveals strong analogy between photon and electron. Atoms of neutral state when at ground level levitate electron of lateral surface at back surface while placing the bit energy at front surface. Gravitation behavior of that electron starts at centre of relaxation point by including the force of side pole where the pulling force of nearby unfilled state of that atom from the front surface results into depict forcing energy shape-like Gaussian distribution symbol with both ends turned called unit photon. The inertia is being involved at each stage of changing position of that electron by introducing the disappearances of forces of two poles resisting against appearances of forces of two opposite poles when rest to motion and motion to rest in the levitating period. The same is the case in the gravitating period of that electron when rest to motion and motion to rest but under different introducing the disappearances of forces of two poles resisting against appearances of forces of two opposite poles. However, in the stage of levitating or gravitating electron only one force is being involved at one time where opposite force is disappeared. The uninterrupted confined inter-state electron-dynamics of neutral state atom while dealing several bits of bit energy having two different shapes result into generate forcing energy shape like a wave. Two bits of bit energy where shape of bit is like opposite integral symbol are being placed along the trajectory of inter-state electron-dynamics during forward-direction cycle and two bits of bit energy where shape of bit like integral symbol are being placed along the trajectory of inter-state electron-dynamics during back-direction cycle. Generating forcing energy of unit photon in each cycle is pushing to rear side by remaining connected till electron is not restoring the state of rest. Silicon atom is considered as a model system of it. Uninterrupted confined inter-state electron-dynamics result into generate forcing energy that can travel immeasurable length and unavailability of necessitating bit energy at any interrupted stage resulting into generate an overt photon. Inter-state electron-dynamics for at least two cycles generate an overt photon –a photon length twice to unit photon. Under certain interaction of unit photon, it divides into two bits of bit energy instead tits and bits of heat. The mechanism of generating photon characteristic current in silicon atom validates that atoms of various elements are two-dimensional elliptical (circular) discs under the neutral state of their electrons. An isolated electron is being grounded under directed forcing energy to impinge a neutral state atom where it gained instantaneous velocity under sinked (merged) energy resulting into transfer it to elongate atom along east west poles. Matter changes the role of energy and force under various sorts of interactions. Here, heat energy and photon energy explore matter at atomic and electron levels, thus, devise science to describe.
