NaBH4-NH3BH3 composite (xSB-AB, x is the molar ratio of SB to AB) has better hydrolysis performance than its monomer, but the hydrogen generation rate (HGR) and hydrogen yield (HY) are still not ideal at room temperature. In this work, a low cost and easily available commercial porous spherical Co3O4 was successfully used to catalyze the hydrolysis of xSB-AB composite. It was found that Co3O4 showed good catalytic performance for the hydrolysis of xSB-AB, and the HY and hydrogen release efficiency (HRE) of 4SB-AB/10 wt%Co3O4 at 40 ℃ reached 2,279.71 mL·g-1 and 89.13%, respectively.

Hydrogenated amorphous silicon/crystalline silicon heterojunction solar cells are currently a hot research topic in the field of photovoltaics, where parasitic absorption due to hydrogenated amorphous silicon layers has not been effectively addressed. For this reason, amorphous silicon/crystalline silicon heterojunction solar cells with localized p-n junctions (HACL cells) have been designed, which can significantly improve the parasitic absorption losses while maintaining the original advantages such as high open-circuit voltage. In this paper, we mainly use ATLAS 2D simulation software to conduct device simulation and parameter optimization of HACL cells, and simulate the effects of factors such as passivation inlet region width, insulation layer width, emitter width, passivation inlet region doping concentration and substrate doping concentration on the cell performance, respectively.

This study blended low-density polyethylene (LDPE) polymer matrix with titanium dioxide (TiO2) nanoparticles as UV blocking filler to create a greenhouse cover film. The best properties for greenhouse application were discovered in TiO2/LDPE nanocomposites films with 5% wt TiO2 nanoparticles, according to the results. TiO2/LDPE nanocomposites films prepared in all conditions can block almost 100% of the UV (200- 400 nm) radiation and show good thermal stability. The TiO2/LDPE nanocomposites films with 5% wt TiO2 nanoparticles has a light transmittance in the visible range of about 80%, sufficient for plant photosynthesis. In addition, it showed good mechanical properties with 12.142 MPa of tensile strength and 319.274% of elongation at break.

Titanate-based luminescent materials have a strong absorption capacity for blue and near-ultraviolet light. Here, a sol-gel method is used to prepare a high-efficiency red phosphor of magnesium titanate Mg2Sr2-xTiO4: Eu3+, Gd3+ doped with rare-earth ions. The optimal doping concentrations of the activator rare earth ion Eu3+ and the sensitizer Gd3+ were investigated. Furthermore, the doping of a certain amount of Sr2+ and Na+ effectively improves the luminescence properties of silicate luminescent materials. The luminescence spectrum shows that the luminescent material has red monochromaticity and the strongest red-light emission is 614nm, which can be used for WLED.

In-situ polymerization of a series of nanocomposites viz. 10, 20, 30, 40 and 50 wt % of Praseodymium Calcium Manganite Oxide (Pr0.75Ca0.25MnO3) (PCM) nano manganites in polypyrrole (PPy) were prepared by chemical polymerization technique. The crystalline nature of all the nanocomposites was confirmed by powder X-ray diffraction (XRD). The orthorhombic structure with space group Pnma was confirmed by the well-fitted Rietveld refined XRD data. The average particle size was observed to be in the range of 42 to 60 nm. Scanning Electron Microscope (SEM) confirmed the spherical nature of the particles. The TEM confirmed the crystallinity and Fourier Transform Infra-Red Spectroscopy (FTIR) showed that the stretching frequencies shifted towards higher frequencies for the nanocomposites suggesting better conjugation due to chemical interaction between the PPy and PCM particles. AC conductivity versus frequency showed that at higher frequencies the AC increases obeying Jonscher’s power law. The correlated barrier hopping (CBH) model is therefore used to describe the conduction mechanism. For all composites, the dielectric constant and tangent loss revealed a frequency- and temperaturedependent character. The real and imaginary impedance were both frequency and temperature dependent. The impedance data were analyzed by fitting Nyquist plots using ZsimpWin software which confirmed non Debye type of behavior. This study highlights on the interactions between conduction processes, grain boundaries, and grains.

CuO/PVA-PEG nanocomposites were prepared by solvent casting method. In XRD spectra, the shifting of peak position and the absence of remaining characteristics peaks of CuO nanoparticles in CuO/PVA-PEG indicates the formation exfoliated nanocomposites. The SEM image reveals the complete dispersion of the nanofillers in polymer matrix. FTIR spectra revealed the formation of strong H-bonds between PVA and PEG during mixing. The absorption and transmission properties of the sample were studied by UV-Vis studies. Z-scan analysis confirms the presence of two-photon absorption in the sample. The synthesized polymer nanocomposite exhibits optical nonlinearity due to the excitonexciton interaction.

In this study, the elastic properties of two high-pressure polymorphs SiO2 nanostructure, stishovite and CaCl2-type, are obtained using Density Functional Theory in 0-80 GPa high pressure domain at zero temperature, based on reducing an interacting many-electron problem to a single-electron problem. It is shown that below 40 GPa, the stishovite phase is more stable; superior to this limit, the CaCl2-type phase becomes more stable, using Gibbs free energy method. Furthermore, the pressure dependence of the density, volume, bulk, and shear moduli were defined in the selected pressure domain.

The study reports feasibility to synthesis copper loaded ZnO nanoparticles using a green synthesis approach influenced by natural extracts from waste maize materials is explored. Different methods were used to investigate the physicochemical characteristics of Cu-ZnO nanoparticles. X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) studies were used to investigate the structural behavior of Cu-ZnO nanoparticles. XRD analysis shows that Cu-ZnO has a typical crystallite size of 23.5nm and a confirmed hexagonal structure. In the wavenumber range 400–600 cm-1 , FT-IR confirmed the presence of metallic elements in Cu-ZnO samples. Through the use of UV–vis spectroscopy, we were able to investigate the optical characteristics of Cu-ZnO. The samples' surface morphology was recorded by FESEM, and their elemental content was evaluated by EDX. This verifies the spherical shape of prepared samples with homogeneous size distributions across their structures. The nanostructured redox behaviour of electroactive Cu-ZnO has been investigated by cyclic voltammetry

ZnO is an important semiconductor due to its unique structural, mechanical and optical properties. In this study pure ZnO pallets and Co3O4 doped ZnO pallets with varying molar concentration of dopant i.e 2% 4% 6% 8% and 10% were prepared by using hydraulic press. X-ray diffraction (XRD), FTIR and Vickers indentation method is used for pallets characterization. The XRD analysis revealed that the pure ZnO and doped ZnO pallet samples have hexagonal wurtzite structure. Vickers Hardness test showed that pure ZnO pallet has maximum hardness as compared to the Co3O4 doped ZnO pallets. FTIR analysis used to examine the bonding properties of synthesized Co doped ZnO. Doped materials with varying concentration were applied against different gram positive and gram negative bacterial strains. A considerable increase in antibacterial activity was observed by increasing the concentration of Co3O4 dopant.

In this study, zinc oxide (ZnO) nanoparticles were modified by means of dispersion using a γ-aminopropyl triethoxysilane coupling agent (KH550), obtaining KH550-ZnO. Then a certain amount of SBMA powder was put into the KH550-ZnO solution, and the ensuing polymerization reaction produced super hydrophilic PSBMA-KH550-ZnO powder. Finally, several polished aluminum sheets were immersed in the PSBMA-KH550-ZnO aqueous solution to start deposition. Upon completion of the deposition, the aluminum sheets were taken out and dried to obtain samples of the ZnO@PSBMA super hydrophilic coating. The structure, morphology and chemical composition of the powders and coatings were investigated by SEM, IR and EDS. The dispersion of KH550-ZnO in aqueous solution was analyzed. The results show that the particle size of KH550-ZnO decreases greatly in aqueous solution. The substrate can be superhydrophilic when deposited in PSBMA-KH550-ZnO aqueous solution for 130 minutes，After 48 hours of coating deposition, the compactness, roughness and friction resistance of the coating are greatly improved. ZnO@PSBMA superhydrophilic coating has good anti-protein, anti-bacterial and anti-algal adhesion properties.
