Abstract: Hydrogels find widespread use in bioapplications for their ability to retain large amounts of water while maintaining structural integrity. In this article we investigate hybrid hydrogels made of nanocellulose and either amino-polyethylenglycol or sodium alginates and we demonstrate two novel results: 1) the biocompatibility of the amino containing hybrid gel synthesized using a simplified receipt that does not require any intermediate synthetic step to functionalize either components and 2) the fact that the fluctuation of the 2nd order correlation function of a Dynamic Light Scattering experiment provides relevant information about the characteristic internal dynamic of the materials across the entire sol-gel transition as well as quantitative information about the ion-specific gel formation. This novel approach offers significantly better temporal (10’s μs) and spatial (10’s μm) resolution than many other state-of-the-art techniques commonly used for such analyses (such as rheometry, SAXS, and NMR) and it might find widespread application in the characterization of the nano to microscale dynamics in soft materials.

Abstract: In the chemical industry, one of the promising areas is the development of effective technologies for obtaining high-quality mineral fertilizers and feed mineral fertilizers from unconditional phosphate raw materials and improving their technical and economic indicators and agrochemical properties of products. Moreover, the solution to these problems should be carried out on the basis of low-grade raw materials poor in phosphorus content. Such low-grade ores include phosphorites of the Chilisay mine. Phosphorites of this deposit have a number of specific features that create certain difficulties and contain a large number of carbonates, in terms of carbon dioxide reaching 4.56-6.34%, as well as glauconites. When decomposing such phosphorites, large volumes of very stable foam are formed, which complicates the decomposition of phosphorus raw materials and reduces the useful volume of the decomposition chamber by 60-80%, increases the loading time of phosphorite and, accordingly, increases the total time of the process. The objective of the work is to research the process of obtaining high-quality monocalcium phosphate, as well as to determine the optimal decomposition parameters of low-grade phosphate raw materials and to increase the product yield. Based on the conducted research of the Chilisayphosphorite decomposition, monocalcium phosphate was obtained.

Abstract:

The dynamic phosphorylation of the human RNA Pol II CTD establishes a code applicable to all eukaryotic transcription processes. However, the ability of these specific post-translational modifications to convey molecular signals through structural changes remains unclear. We previously explained that each gene can be modeled as a combination of n circuits connected in parallel. RNA Pol II accesses these circuits and, through a series of pulses, matches the resonance frequency of the DNA qubits, enabling it to extract genetic information and quantum teleport it. Negatively charged phosphates react under RNA Pol II catalysis, increasing the electron density on the deoxyribose acceptor carbon. The first pulse of phosphorylation connects tyrosine to the nitrogenous base, while the subsequent pulses link the protein to molecular water through hydrogen bonds. The coupling of hydrogen proton transfer with electron transfer in water generates a supercurrent, which is explained by the correlation of pairs of the same type of fermions exchanging a boson. All these changes lead to the formation of a molecular protein-DNA-water condensate.

Abstract: Cellulose and starch-cellulose composite aerogels were obtained using green cel-lulose from rice straw (RS) purified with a more environmentally friendly process. Pure starch aerogels were also obtained for comparison purposes. The effect of the aerogel crosslinking with polyamideamine-epichlorohydrin (PAE) was also analysed. The properties of the cellulose aerogels were in the range of those reported using other RS cellulose fibres with similar compositions. Blending with starch implied a decrease in the liquid water absorption capacity but an increase in the mechanical strength and flexibility and oil absorption capacity, compared to pure cellulose aerogels. Crosslink-ing with PAE promoted the water adsorption capacity of all aerogels and the oil ab-sorption capacity and mechanical strength of cellulose aerogels but did not benefit the properties of cellulose-starch composites or pure starch areoles due to specific interac-tions with starch that negatively affect the aerogel structure. Therefore, it was possible to obtain cellulose and cellulose-starch composite aerogels from RS green cellulose with modulated properties for different applications.

Abstract: Cellulose acetate (CA) motion picture films are subjected to degradation especially due to the “vinegar syndrome”, a de-acetylation process catalyzed by high temperature, humidity, and acidity. Acetic acid is released as a by-product of this reaction and acts as a catalyst that triggers an autocatalytic process. The main aim of this study was to evaluate the use of metal oxide, hydroxide, and carbonate nanoparticles, as well as their composite inorganic-organic systems, for the ad-sorption of acetic acid and the inhibition of the deacetylation process. Various nanoparticles [Ca(OH)2, ZnO and CaCO3] were compared in terms of their ability to adsorb glacial acetic acid vapors through gravimetry analysis, Fourier Transform Infrared (FTIR) Spectroscopy, X-ray dif-fraction (XRD), and Thermogravimetric Analysis (TGA). The variation in the size and morphology of the nanoparticles was investigated via Scanning Electron Microscopy (SEM), too. Subsequently, the most promising nanoparticles (ZnO) were incorporated into composite organic-inorganic systems, made of Whatman paper (WP) and Poly-Vinyl-alcohol Formaldehyde (PVF) xerogels, and their ability to adsorb acetic acid vapors was again evaluated. Finally, the performance of both the pure ZnO nanoparticles and the organic-inorganic composite systems as inhibitors of the “vinegar syndrome” was assessed on artificially degraded motion picture films using a specifically de-veloped and validated multi-analytical protocol.

Abstract: One of the main plants that people grow is the fig (Ficus carica L.). Nearly every component of the fig is utilized for food and medicine, but handling and storing them after harvest is challenging because of their extreme perishability. Response Surface Methodology (RSM) and mixture design were used to optimize the composition of the fig gum jelly. The percentages of fig paste (x1), k-carrageenan (x2), and honey (x3) are independent variables. Nine reactions were assessed by the sensory panel, which included ten elements of both sexes. Y1: Exceptional, Y2: Openness, Y3: Fragrant, Texture A in Y4, Texture C in Y5, Sweetness A (Y6), Sweetness B (Y7), Mouthfeel in Y8 and Y9 - nine polynomial models were created by the overall opinion. With 55 % fig paste, 15 % k-carrageenan, and 30 % honey, the optimal fig gum jelly composition was obtained through numerical optimization. With an astounding 0.3 desirability, the same panel's validation favored the best formulation for every response.

Abstract:

Solid Fe catalysts supported on SiO2 with Lewis and Brönsted acidity were synthesized using the sol-gel methodology. FTIR spectroscopy, XRD, Raman spectroscopy, BET isotherms, and SEM characterized the materials. Subsequently, they were used to dehydrate xylose to obtain furfural. It was observed that increasing the metal loading from 0.5 % to 1.5 % by mass increases the selectivity to furfural up to 40.09 %; in addition to this, it was observed that the calcination temperature has an effect concerning the conversion since the materials calcined at 450 °C present higher xylose conversion concerning the materials calcined at 750 °C. Finally, it was observed that the catalysts are active and effective in obtaining furfural from hydrolysates obtained from hydrothermal treatments of the residual biomass of the coffee crop, obtaining an average of 9.11 mg/g of furfural per gram of biomass.

Abstract: Recently single-cone hydraulic canal filling technique using bioceramic sealers brought a difficulty of retreatment due to the mechanical properties of the bioceramic sealers. This study assessed the effectiveness of four nickel-titanium rotary files in removing gutta-percha and bioceramic sealer from molar root canals in vitro. Eighty-eight root canals from extracted molars were instrumented with Vortex Blue rotary files and filled with gutta-percha and bioceramic sealer using a single-cone technique. After 30 days, the filled canals were randomly divided into four groups according to the file used for re-instrumentation: ProTaper Gold (PTG), Endo ReStart (ERS), XP-3D Shaper (XPD), and HyFlex Remover (HFR). The study assessed whether root canal filling material removal and patency were achieved within a 10-minute time frame, recording the time required in seconds. The rate of regaining patency and the time required to achieve patency were compared between groups using a generalized linear model. Scanning electron microscopy were used to evaluate the mechanical changes on the files. The patency rate of XPD and HFR was significantly higher than PTG. ERS and XPD demonstrated shorter patency times than HFR and significantly shorter patency times than PTG. SEM images revealed a varied range of reverse windings across file groups. PTG and ERS exhibited microcracks and fractured tips, while XPD and HFR did not display these mechanical alterations. The four file systems in this study displayed varying levels of effectiveness in the retreatment of root canals filled with bioceramic sealers.

Abstract: During the global energy transition, electric vehicles and electrochemical energy storage systems are rapidly gaining popularity, leading to a strong demand for lithium battery technology with high energy density and long lifespan. However, the highly integrated components, such as flammable polymers, organic electrolytes, and high energy density electrodes, make the batteries susceptible to thermal runaway (TR) under abuse conditions, resulting in fire and explosion incidents. The key approach to ensure the safe operation of LIBs including detecting and responding to thermal runaway characteristic parameters, that enables premature response window for disaster incidents and interruption of disaster propagation chain. This paper begins with the development characteristics of thermal runaway in lithium batteries and provides a review of research progress in areas such as the design principle in key battery components especially for polymers, multi-parameter responsive characteristics, and mechanisms for blocking thermal runaway. It analyzes the challenges faced by inorganic and organic materials based on multi-parameter responses in the fields of thermal response and thermal runaway suppression, and it looks ahead to research directions in the design and application of intelligent safety materials in new battery systems and complex scenarios. The findings aim to provide scientific guidance for promoting the design and application of high-safety lithium batteries.

Abstract: Introduction: 3D printing resins have gained popularity in dentistry due to their practicality and reproducibility. However, differences in chemical composition have a direct influence on the mechanical properties of these materials and the various evaluation methods have generated different results which make it difficult to compare their properties. Objective: The aim of this study was to evaluate the influence of the orientation of the impression layers on the mechanical properties (flexural strength and flexural modulus) of biocompatible printed resins. Methods: 100 specimens (n=20) were made from bars measuring 2 x 2 x 25 mm, divided according to the angulation relative to the printing platform (V0, V22.5, V45, V67.5, V90). The bars were designed using Autodesk Meshmixer CAD software and printed on a 3D LCD printer. For the control group, composite resin specimens were made following the same patterns as the printed resins. These bars were subjected to 3-point bending tests on a universal testing machine and flexural strength (FS) and flexural modulus (MF) were evaluated. Results: The mean values of flexural strength and flexural modulus showed no statistically significant differences between the groups. The composite resin control group showed significantly higher mean values in both factors analyzed. Conclusion: It can be concluded that the groups showed minimal differences in the angles studied in both flexural strength and flexural modulus, showing the anisotropic behavior of the restorative material manufactured by 3D printing, suggesting that the choice of any printing angle can determine the applicability according to the characteristics and function of the object to be printed.

Abstract: With the rapid development of high-speed imaging, aerospace, and telecommunications, high-performance photodetectors across a broadband spectrum are urgently demanded. Due to abundant surface configurations and exceptional electronic properties, two-dimensional (2D) materials are considered as ideal candidates for broadband photodetection applications. However, broadband photodetectors with both high responsivity and fast response time remain a challenging issue for all the researchers. This review paper is organized as follows. Section I introduces the fundamental properties and broadband photodetection performances of transition metal dichalcogenides (TMDCs), perovskites, topological insulators, graphene, and black phosphorus (BP). This section provides an in-depth analysis of their unique optoelectronic properties and probes the intrinsic physical mechanism of broadband detection. In Section II, some innovative strategies are given to expand the detection wavelength range of 2D material-based photodetectors and enhance their overall performances. Among them, chemical doping, defect engineering, heterostructure construction, and strain engineering way are found to be mor effective for improving their photodetection performances. The last section addresses the challenges and future prospects of 2D material-based broadband photodetectors. Furthermore, to meet the practical requirements for very large-scale integration (VLSI) applications, their work reliability, production cost and compatibility with planar technology should be paid much attention.

Abstract: Lead-free perovskites have garnered significant attention as a promising alternative to traditional toxic Pb-containing materials in solar cells. Although lead-based perovskites have achieved high solar energy conversion efficiencies (>25%), their contamination and environmental risks limit their commercial application. Materials based on tin (Sn), bismuth (Bi), antimony (Sb), and germanium (Ge) exhibit the potential to replace lead-based perovskites due to their similar optical and electrochemical properties and lower toxicity. However, key challenges remain, including their lower stability, susceptibility to oxidation (notably Sn2+), and reduced efficiency compared to Pb-based materials. This article reviews recent advancements in the synthesis of lead-free perovskites, methods for improving their structural and functional properties, and their prospects for application in solar cells. The presented review consolidates data on the photovoltaic efficiency, stability, durability, and environmental safety of lead-free perovskites. It discusses their future market potential, emphasizing their environmental friendliness, wide applicability in solar cells, light-emitting devices, neuromorphic systems for artificial intelligence, and microelectronics, as well as scalable production methods that have been developed.The need for further research to optimize their properties and scale up technologies for industrial applications is highlighted.The analysis demonstrates that lead-free perovskites hold substantial promise as a foundation for the next generation of solar cells, providing an environmentally clean and sustainable solution for renewable energy. Nonetheless, addressing the technological challenges related to their stability and scalability is critical for unlocking their full potential.

Abstract: The mesoscopic phase separation in two- and three-dimensional gels has been studied by computer simulation of a bead-spring model of Lennard-Jones particles. The formation of complex networks of high density phase (HDP) has been investigated and partially explained with competing short- and long-range energies. HDP network formation was found to occur at certain combinations of temperature and spring coefficient, given sufficient particle density. The morphology of the HDP networks changed with these three parameters. HDP networks became more faceted with higher spring coefficients, wider but less dense at higher temperatures and more voluminous and compact at larger densities. HDP network formation was preceded by a stage of HDP precipitation and followed by a stage of surface minimization.

Abstract: Pectin is a complex and versatile polysaccharide crucial for various industries. It functions as a thickener, gelling agent, emulsifier, and low-calorie food. Its anti-inflammatory and immunomodulatory properties have attracted biomedical interest, while its biodegradability and biocompatibility make it valuable for biomaterial applications. The effectiveness of these applications depends on the quality of pectin extraction procedures While traditional extraction methods exist, green methodologies and alternative techniques have improved pectin's physicochemical properties—a significant advantage for industrial applications. Pectin can be extracted from various sources, with its molecular structure and functional groups analyzed through different characterization techniques. Modern green extraction methods include ultrasound-assisted extraction, pulsed ultrasound-assisted extraction, pulsed electric field, moderate electric field mediated extraction, microwave-assisted extraction, subcritical water extraction, enzyme-assisted extraction, ohmic heating-assisted extraction, ultrasound-assisted microwave extraction, ultrasound-assisted ohmic heating extraction, hydrothermal processing, high-pressure processing extraction, and dielectric barrier discharge extraction. This review examines these methods' advantages and disadvantages, along with their applications and future possibilities; it serves as a comprehensive guide for researchers exploring new pectin-rich sources and green extraction technologies for commercial applications.

Abstract: Boron Neutron Capture Therapy is a re-emerging therapy for the treatment of cancer, and the development of new neutron-reactive nuclei carriers with enhanced efficiency is of great importance. In this work we propose three new boron-based solid compounds, of formula [Ca(H2O)6](C14H8O6B)2 (CaSB), [Cu(C14H8O6B)] (CuSB), and [Li(C14H8O6B)(H2O)] (LiSB), usable as nanoparticles for the carriage of the 10B isotope. The copper atom in CuSB was introduced because it is known that its presence magnifies the effect of the radiation into cells. Furthermore, the lithium atom in LiSB allows to include also the 6Li isotope, that can take part in the nuclear reactions enhancing the efficiency of the anti-cancer treatment. The compounds were characterized with single crystal X-ray diffraction, to compare the densities of the reactive isotopes in the materials, a key parameter related to the efficiency of the materials. In this work, we used a computational method to calculate the dose absorbed by a tumor mass treated with nanoparticles of the compounds, in order to select the most efficient one for the therapy. The encouraging results are reported in this work.

Abstract:

4-Aminoquinoline derivatives were synthesized on a small scale using a novel microwave-assisted method, and scaled up in sealed tubes. The synthesis adhered to green chemistry principles, employing a solvent-free approach for both the reaction and purification. The purification was achieved through simple washing, no need for column chromatography. All reactions were conducted at temperatures between 90–150 ºC within 90–120 minutes, achieving yields of up to 95%. The products were characterized using FT-IR, 1H- and 13C-NMR spectroscopy, and HR-MS spectrometry. Antibacterial and antifungal activity testing revealed that four compounds exhibited moderate antibacterial activity. Compound 6-chlorocyclopentaquinolinamine demonstrated a strong MIC of 0.125 mM against MRSA, while compound 2-fluorocycloheptaquinolinamine showed a MIC of 0.25 mM against S. pyogenes. A Structure-Activity Relationship (SAR) docking study was conducted within the Penicillin Binding Protein (PBP) binding site. Docking analysis of anti-MRSA com-pounds 7-chlorophenylquinolinamine, 6-chlorocyclopentaquinolinamine, and 2-fluorocycloheptaquinolinamine in the MRSA PBP2a binding pocket (PDB: 4DK1) revealed that 6-chlorocyclopentaquinolinamine and 7-chlorophenylquinolinamine interacted via hydrophobic (ALA601, ILE614), hydrogen bonding (GLN521), and halogen interactions (TYR519, THR399). Compound 6-chlorocyclopentaquinolinamine exhibited superior MRSA inhibition (20 mm inhibition zone vs. 12.5 mm for 7-chlorophenylquinolinamine), attributed to additional π-alkyl interactions and favorable docking parameters, including higher Ligscore2 (4.03), PLP1 (59.15), and Dock Score (34.31). In contrast, compound 2-fluorocycloheptaquinolinamine exhibited weaker activity due to its bulky structure, limited interactions, and less favorable docking scores.

Abstract: The Mg-Y-Zn magnesium alloy system is known for the presence of Long-Period Stacking Ordered (LPSO) phases that improves strength and ductility with minimal amounts of alloying elements. Even better improvements are associated with the specific microstructure known as the Mille-Feuille structure (MFS) that can occur in this alloy as well after proper heat treatment. This study systematically compares the traditional ingot metallurgy method with the Bridgman method (slow cooling), coupled with diverse heat treatments and extrusion process. Microscopic analyses reveal variations in the presence of LPSO phases, Mille-Feuille structure, and especially grain size, leading to divergent mechanical and corrosion properties. The Bridgman approach surprisingly stands out, ensuring superior mechanical properties due to kink and texture strengthening.

Abstract: Detecting low nitrogen dioxide concentrations (NO₂) is crucial for environmental monitoring and health protection. In this paper, we report the synergistic effect of decorating nitrogen-doped reduced graphene oxide (N-rGO) with nickel oxide (NiO) nanoparticles for developing highly selective and sensitive chemiresistive NO₂ gas sensors. The N-rGO/NiO sensor was synthesized straightforwardly, ensuring uniform decoration of NiO nanoparticles on the N-rGO surface. Comprehensive characterization using SEM, TEM, XRD, and Raman spectroscopy confirmed the successful integration of NiO nanoparticles with N-rGO and revealed key structural and morphological features contributing to its enhanced sensing performance. As a result. Compared to the N-rGO, the NiO/N-rGO nanohybrids exhibit a boosted response of 5 orders of magnitude towards low concentrations of NO2 (< 1 ppm) at 100 °C. Moreover, the present device has an outstanding performance, high sensitivity, and low limit of detection (< 1 ppb). The findings pave the way for integrating these sensors into advanced applications, including environmental monitoring and IoT-enabled air quality management systems.

Abstract: Removing high-concentration organic dye from wastewater is of great concern because the hazards can cause serious damage to the environment and human health. In this study, the hybrid dimensionally stable anode (DSA) with Ce-doped and SnO2- Sb2O5 intermediate layer was fabricated and used for the electro-catalytic oxidation of three kinds ultra-high concentration organic dyes.Scanning electron microscopy (SEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) confirmed the more dense surface structure and morphology of the composite Ti/SnO2-Sb2O5/Ce-PbO2 electrode, Moreover, the electrode exhibited excellent oxygen evolution potential of 1.58 V. The effect on the removal efficiencies of high concentrations up to 1 g/L of methyl orange, methylene blue, and neutral red solutions with the above composite electrode were investigated.The research results illustrated that target molecules in the three different dye solutions were rapidly decolorized and decomposed by electro-catalytic oxidation less than 35 min. Additionally, the degradation process still followed pseudo-first-order kinetics for high concentrations dye solution. The removal efficiency of TOC and COD for the three dye solutions was more than 98%, and the results of the GC-MS analysis showed that it had the best degradation effects for neutral red, which decomposed more thoroughly. More than 80 h of accelerated life also revealed excellent performance of the composite electrode in face of high-concentration dye solution degradation. Considering these results, the Ti/SnO2-Sb2O5/Ce-PbO2 anode could be utilized to treat wastewater containing high-concentration dyes with high efficiency.
