Improving the quality of natural water purification is one of the priority areas in the research of scientific communities in the field of ecology. At the same time, the task is to achieve optimal efficiency at a low cost of the technological process. The solution in this case is the use of materials necessary for cleaning, in particular, sorbents from natural raw materials, including agricultural waste. At present, a sufficient number of research results have been published confirming the effectiveness of the sorbent from biochar of various agricultural wastes, as well as from rice straw biochar. This article proposes an innovative method for modifying biochar from rice straw, which allows the use of the material as a sorbent with a disinfecting effect. The method consists in processing biochar in a process activation apparatus (PAP) in a solution of silver nitrate with the release in the form of a carbon nanomaterial with attached metallic silver ions on the surface of biochar particles. Rice straw biochar was mixed in distilled water with silver nitrate AgNO3 and placed in the AAP in a replaceable insert with ferromagnetic particles that have a magnetostrictive effect under the influence of an electromagnetic field. Next, the contact of biochar impregnated with a solution of silver nitrate and ferromagnetic particles was carried out for 2 minutes under electromagnetic influence, after which the treated sample was dried in an oven for 4 hours at t=105ºС, followed by calcination in a muffle furnace at 450ºС for 3 hours. The resulting silver-containing sorbent was subjected to a physicochemical analysis of its properties, photographs of electron microscopy were also obtained, and a bacteriological analysis of the effectiveness of the sorbent on natural water was carried out. According to the results of the analyzes, the silver-containing sorbent is a mesoporous nanomaterial with an average mesopore diameter for desorption of 196 Å, a relative volume of pores with a diameter of up to 900 Å 0.034 cm³/g,, specific surface 7.45 m²/g and a content of metallic silver ions on the surface of the sorbent particles of (Ag) 16.7%, oxygen (O) 54.9%, unexpectedly (С) 13.7%, silicon (Si) 8.1%. Laboratory studies for the bacteriological analysis of natural water consisted in the sorption processing of the selected samples in the carbonization mode, followed by sedimentation after the introduction of the reagent (a mixture of coagulant and flocculant). The analysis was carried out on three indicators - total microbial count (TMC), total coliform bacteria (TCB) and thermotolerant coliform bacteria (TCB). According to the research results, the sorbent showed its disinfecting properties and confirmed its high efficiency (90,48%-100%).

There is a misconception about using the terms photon and electron. When the electron of the outer ring in the silicon atom executes interstate dynamics for only one cycle, it generates force and energy for the unit photon. The unit photon has a shape like Gaussian distribution in turned ends. When the photon of suitable length interacts with the side of the laterally orientated electron of a semisolid or solid atom, it converts into heat. Under the approximate angle of 90º, when a photon interacts with the tip of a laterally orientated electron, it divides into bits of energy having a shape like integral symbols. Solid or semisolid element atoms can reveal the phenomena of heat energy if their electrons deal with interactions of photons. In the neutral state silicon atom, the center acts as the reference point for electrons executing interstate dynamics, and the north-south tips of the electrons remain along the north-south poles. The energy shapes around the force tracing along the trajectory of electron dynamics. Under dynamics, two forces exert on the electron for one time, whereas two forces shape from opposite sides. In interstate dynamics, the electron of the outer ring first reaches the maximum limit point, where the one-bit energy shapes. In the remaining half cycle, that electron again shapes one-bit energy. When there is an uninterrupted supply of heat energy to the silicon atom, electron dynamics generate the photon having a shape-like wave. Path-independent but interstate-dependent forces take over the control of an electron. That electron executes dynamics nearly at the speed of light. In dynamics, the conservative forces exert on the position-acquiring electron. A photon can be in unending length if the electron dynamics remain uninterrupted. The changing aspect of the electron recalls the auxiliary moment of inertia at each point of turning. Atoms of suitable elements generate differently shaped photons when executing dynamics for the outer ring electrons. Thus, they can also reveal the phenomenon of photon energy.

The microstructure evolution, superplasticity, and room temperature mechanical properties of Ti-4%Al-1%V-3%Mo alloys modified with 0.01-2 wt.% boron were investigated. Increasing the boron content from 0 to 0.1 wt.% effectively refined prior β-grains, reducing a mean grain size from ~700 µm to ~210 µm. Whiskers of the TiB phase with a size in a range of 0.7-2.9 µm were observed after solidification and thermomechanical processing. Alloys with 0.01-0.1 wt.% boron exhibited similar superplastic elongations and strain rate sensitivity coefficient m of 0.4-0.5 at a strain rate of 1×10-3 s-1 and the elongation to failure decreased from 1000% at 875°С to 400-500% at 700°С. Along with this, the minor boron addition effectively decreased flow stress values, especially at 775 °C, that was explained by the acceleration of the recrystallization and globularization of the microstructure at the initial stage of deformation. Recrystallization-induced decrease in yield strength from 770 MPa to 680 MPa was observed with an increase in boron content from 0 to 0.1 wt.%. Heat treatment increased post-forming strength characteristics for the alloys with 0.01-0.1 wt.% boron by 90–140 MPa without ductility reduction. Alloys with 1-2 wt.% B demonstrated the opposite behavior. The grain refinement effect was not revealed, and prior β grain sizes were ~670-750 µm after solidification. Thermomechanical processing promoted the fragmentation of boride whiskers and the formation of near-spherical particles with a size of ~1 μm for the alloy with a eutectic concentration of 2 wt.% B. A high fraction of borides, ~5-11%, in the alloys with 1-2 wt.% B deteriorated the superplastic properties and drastically decreased ductility at room temperature. The alloy with 2 wt.% B demonstrated non-superplastic behavior and a low level of mechanical properties, meanwhile, the alloy with 1% boron exhibited high-temperature superplasticity at 875 °C with elongation of ~500%, and yield strength of 830 MPa, ultimate tensile strength of 1020 MPa at a room temperature after 100% of superplastic deformation.

November 15th, 2022 was selected as the day where the human population reached the 8 billion mark [1]. This new reality will force the governments around the world to find ways to sustainably produce and secure food, water, and energy for their countries [2-4]. In terms of water, its quality and availability has been a matter of great concern in recent decades [5], especially with the emergence of new organic and inorganic pollutants [6]. Among organic contaminants, the detection of trace amounts of fluoroquinolone antibiotics, such as ciprofloxacin (CFX) and levofloxacin (LFX), in natural water bodies, has been of great concern in the scientific community [7,8]. Some of the side effects of the consumption of these antibiotics are nausea, diarrhea, abdominal pain, rash, low sugar levels, and antibiotic resistance to bacterial infections, among others [9,10]. It was estimated that in 2019 more than 1.27 million people died due to antibiotic-resistant bacterial infections [11], and this number is expected to rise to 10 million by 2050, if the trend continues [12]. Because of this, new ways to degrade antibiotics from water have been developed over the years. A method that has been implemented for some time is the use of photocatalysts for the degradation of these compounds in water [13]. Semiconductors such as titanium oxide (TiO2), zinc oxide (ZnO), zinc sulfide (ZnS), cadmium sulfide (CdS), strontium peroxide (SnO2), or tungsten trioxide (WO3), among others, are commonly used in photocatalytic processes [14-16]. Zinc oxide has been widely used due to its low cost and stability in aqueous solution, easy production, and because it is an environmentally friendly material [17,18]. It has been identified that some of the disadvantages of ZnO as photocatalyst are photocorrosion, recombination of electron-hole pairs, fast backward reactions, and inability to use visible light [18]. Multiple approaches have been implemented over the years to reduce these limitations. One of them is the use of noble metals such as platinum (Pt), gold (Au), or even silver (Ag) as cocatalysts [15-17,19]. These metals can increase the photocatalytic activity by reducing the recombination of electron-hole pairs, as well allowing the use of visible light [20]. For example, Quin and coworkers [21] prepared a bio-inspired hierarchical assembly of carbonized spinach leaves@Au/ZnO for the degradation of CFX under visible light. The results showed a degradation of 61% of the antibiotic in a period of 180 minutes. Chankhanittha et al. [22] developed different Ag@ZnO composites for the complete degradation of red dye and ofloxacin antibiotic in 25 and 80 minutes, respectively. The researchers attributed the improved photoactivity to the high electron-hole separation efficiency at the photocatalyst interface, as well as the creation of the Schottky barrier at the silver-zinc oxide interface.

Oxidation reactions on semiconducting metal oxides (SMOs) surfaces have been extensively worked on in catalysis, fuel cells, and sensors. SMOs engaged powerfully in energy-related applications such as batteries, supercapacitors, solid oxide fuel cells (SOFCs), and chemical gas sensors. The deep understanding of SMO surface and oxygen interactions and defect engineering has become significant because all those mentioned applications are based on the adsorption/absorption and consumption/transportation of adsorbed (physisorbed-chemisorbed) oxygen. More understanding of adsorbed oxygen and oxygen vacancies (〖V_O^•,V〗_O^(••)) is needed, as the former is the vital requirement for sensing chemical reactions, while the latter facilitates the replenishment of adsorbed oxygen ions on the surface. We determined the relation between sensor response (sensitivity) and the amounts of adsorbed oxygen ions (O_(2(ads))^-,O_((ads),)^- O_2(ads)^(2-),O_((ads))^(2-)), water/hydroxide groups (H2O/OH^-), oxygen vacancies (〖V_O^•,V〗_O^(••)), and ordinary lattice oxygen ions (O_lattice^(2-)) as a function of temperature. During hydrogen (H2) testing, the different oxidation states (W6+, W5+, and W4+) of WO3 were quantified and correlated with oxygen vacancy formation (〖V_O^•,V〗_O^(••)). We used a combined application of XPS, UPS, XPEEM-LEEM, and chemical, electrical and sensory analysis for H2 sensing. We established a correlation between the H2 sensing mechanism of WO3, sensor signal magnitude, the amount of adsorbed oxygen ions, and sensor testing temperature. This paper also provides a review of the detection, quantification, and identification of different adsorbed oxygen species. The different surface and bulk-sensitive characterization techniques relevant to analyzing the SMOs-based sensor are tabulated, providing the sensor designer with the chemical, physical, and electronic information extracted from each technique.
