Generally, salt precursors have been investigated for the production of nanoparticles with semiconducting properties such as metal chalcogenides and others. They have demonstrated excellent features for the ease of converting them to nanoparticles. Thermal decomposition and solvothermal processes are often followed to produce particles with stabilizers of varied ranges of size with improved size control dependent on the set collective conditions and the intended applications. In this study, silver (Ag) and copper (Cu) nanoparticles were synthesized using the thermal decomposition method in the presence of oleylamine as a capping agent in order to produce good stable uniform monodispersed nanoparticles. Lower amounts of Ag and Cu precursors (0.1 - 0.2 g) were used to study their effect on the size and morphology of the nanoparticles. The synthesized nanoparticles under various conditions were characterized using UV/Vis and PL spectroscopy, TEM, and XRD. It was observed that an increase in the precursor concentration led to an increase in particle size with varying morphologies for both Ag and Cu nanoparticles. The TEM images of Ag nanoparticles showed that uniform morphology and spherical shape were observed with narrow diameters ranging from 5.9 to 6.8 nm. However, for Cu nanoparticles, uniform morphology and spherical shape were only observed at a precursor concentration of 0.15 g with an average diameter of 7.8 nm. The XRD results of both Ag and Cu nanoparticles showed peaks that were identified as Ag and Cu in the face-centred cubic.

Collagen membranes have been widely investigated in animal studies and human clinical studies, and have demonstrated excellent biocompatibility, biodegradability and cell affinity. Membrane porosity and 3D architecture are considered to be crucial for cellular infiltration and proliferation, in the process of wound heling. In this context, the aim of our study was the prepare and to investigate comparatively the structural and morphological properties of collagenic membranes modified with a natural bio-compound (respectively azelaic acid) and to evaluate their bio-integration and immune response in the framework of an animal model. Our results shown a porous structure with a honeycomb-style architecture achieved as a result of azelaic acid incorporation in collagenic membrane, with a beneficial effect on tissue remodelling and rapid healing. The bio-integration of azelaic acid-collagenic membrane was faster compared to pure collagenic one, with only minor inflammatory events.

In this paper, Cr2O3-25TiO2 composite coatings were prepared on the surface of steel structure samples by atmospheric plasma spraying. The phase composition, microstructure, microhardness and long-term immersion corrosion behavior in 3.5 wt.% NaCl solution of Cr2O3-25TiO2 composite coatings were studied. The corrosion behavior of Cr2O3-25TiO2 composite coating was analyzed by potentiodynamic polarization and electrochemical impedance spectroscopy. The impedance data were fitted into an appropriate equivalent circuit to explain the electrochemical corrosion behavior of the coating at different stages. The results of scanning electron microscopy showed that the Cr2O3-25TiO2 composite coating was agglomerated, and the rhombohedral Cr2O3 powder was wrapped around the rhombohedral TiO2 powder. The coating melted completely without obvious defected. The XRD results showed that no phase transformation occurred in the Cr2O3-25TiO2 composite coating. The Cr2O3-25TiO2 coatings showed high corrosion resistance and good passivation behavior in the initial stage of corrosion. The coating itself did not corrode. With the extension of corrosion time, the corrosive medium had passed through the pores between the coatings, resulting in the contact between the corrosive medium and the matrix interface, resulting in the matrix corrosion damage. Corrosion products would deposit on the surface of the coating, blocking the pores between the coatings, and the corrosion rate would be reduced.

A series of phosphate glass with the following formulation was manufactured using the melt quenching procedure: 3As2O3 – 37PbO – (60 − 𝑥𝑥) P2O5- 𝑥𝑥 WO3, 𝑥𝑥 = (0 ≤ 𝑥𝑥 ≤ 5 mol. %). The glasses' physical and other structural characteristics were examined in depth. The basic structural properties of the materials were examined using a variety of characterization procedures, such as XRD and FT-IR. With increasing WO3 concentration, the phosphate network evolves, leading to depolymerization of the glass network, according to the FT-IR analysis. With increasing WO3, the physical, mechanical, and structural parameters were enhanced like glass density, longitudinal and shear speeds, and all elastic moduli. Because of P–O–W bonds in the glass network are stronger than P–O– P bonds, the radiation characteristics were enhanced as the content of WO3 increased. The interpretation of the parameters showed that the glass in the statement is an excellent candidate for photon shielding applications.
一系列磷酸盐玻璃具有以下配方是生产使用熔体淬火过程:3 as2o3 - 37 pbo(60−𝑥𝑥)P2O5——𝑥𝑥WO3,𝑥𝑥=(0≤𝑥𝑥≤5摩尔。%)。对玻璃的物理和其他结构特性进行了深入的研究。采用XRD和FT-IR等多种表征手段对材料的基本结构性能进行了表征。根据FT-IR分析，随着WO3浓度的增加，磷酸盐网络演变，导致玻璃网络解聚。随着WO3的增加，玻璃密度、纵向和剪切速度以及所有弹性模量等物理、机械和结构参数都得到了增强。由于玻璃网络中的P - o - w键比P - o - P键更强，因此随着WO3含量的增加，辐射特性增强。对参数的解释表明，声明中的玻璃是光子屏蔽应用的理想候选者。

To investigate the influence of CeO2 nanoparticles on the evaporation characteristics of fuel droplets, numerical simulation for single nano-fuel droplet evaporation was conducted based on ANSYS FLUENT software according to the single droplet evaporation visualization experiment. And the effects of nanoparticles’ concentration and size on the temperature and fuel-vapor concentration during the evaporation of were emphatically discussed. The simulation results showed that the temperature field and concentration field were distributed in a gradient. Nano-fuel droplets absorbed heat from the external environment, and the temperature of the nano-fuel droplets kept rising until reaching the evaporation equilibrium temperature. The evaporation equilibrium temperature of nano-fuels droplets was higher than that of N-tetradecane (C14) at the temperature of 573 K. In addition, it increased with the increment of nanoparticle concentration and reduction of the nanoparticle size. In the beginning of the evaporation, the vapor volume fraction of nano-fuel was relatively low and it increased slowly with time. As the evaporation process continued, the evaporation rate of nano-fuel droplets increased. The liquid nano-fuel was constantly evaporating to the fuel vapor, and the vapor volume fraction was increased. The vapor volume fraction was increased during the same evaporation period when elevated nanoparticles concentration and minished nanoparticles size.

Firstly, H3[P(W3O10)4]@MOF-199 nanoparticles (PTA@MOF-199) of uniform morphology, about 80-125 nm, were successfully synthesized by a simple one-step reaction under solvothermal conditions and then these as-prepared nanoparticles were incorporated into polyvinyl alcohol (PVA) and polyvinyl pyrrolidone (PVP) with solution-cast technique to fabricate a series of proton-conducting mixed matrix membranes with different mass percentage of PTA@MOF-199. These membranes were characterized by XRD and FT-IR. Afterwards, the influence of the mass percentage of PTA@MOF-199 and temperature on the proton-conducting properties were evaluated. Our work confirmed that the polyoxometalate (POM) functionalized MOFs had great application potential as proton conductive materials and provided a basis for further studies on other POM@MOFs based proton-conducting membranes fabrication.
