Summary: An analytical model is developed to study the composition-dependent structure of amorphous aluminosilicate materials. The model provides insights into the decrease in aluminum atoms and the increase in aluminum-oxygen bonds with increasing cation field strength. It accurately predicts the fraction of non-bridging oxygen atoms in different compositions. However, for certain compositions, there may be an excess of non-bridging oxygen atoms.

Summary: This study aimed to understand the influence of active nano-sized ingredients on the thermal stability of nanocomposites and investigate the chemical changes that occur after thermal treatment at 800 degrees C. Metakaolin-phosphate geopolymer (M) nanocomposites were formed by incorporating 1% nanoalumina (MA) and 1% nanosilica (MS) at a slightly elevated temperature, followed by air-annealing. The results showed that the addition of nanoalumina strengthened silicoalumina phosphate links and aluminum phosphate phases, while the addition of nanosilica produced silicoalumina hydrates. Microstructural and spectroscopic analyses confirmed the presence of crystalline and non-crystalline phases in the heated samples. The significant changes in the composites under thermal treatment were attributed to the coordination change of P bond and its migration, coupled with desilication of silicoalumino phosphate.

Summary: The influence of molybdenum on varying phosphate network was investigated by preparing three series of MoO3-CaO-P2O5 glasses. Molybdenum was found to predominantly exist as MoVIO22+ in the glasses, forming donor-acceptor bonds with non-bridging phosphate oxygens. A chemical model was created to explain the actual chemical compositions and compositional dependencies of the glasses, including their glass transition temperature and coefficient of thermal expansion.

Summary: A conformal amorphous titanyl phosphate (a-TP) overlayer on nanoparticulate TiO2 surfaces can modulate the surface adsorption energies for reaction intermediates, favoring the production of H2O2 through water oxidation reaction (WOR) over the competing O2 evolution reaction. The a-TP overlayer also strengthens the built-in electric field, resulting in favorable kinetics for H2O2 production. This strategy demonstrates efficient solar-to-chemical energy conversion for PEC H2O2 production.

Summary: Due to the interest in applications of zeolitic materials and challenges associated with traditional synthesis methods, a new synthesis approach for aluminophosphate (AlPO) zeotypes has been developed. By calcinating amorphous precursors at moderate temperatures and short reaction times, highly crystalline AlPO zeotypes with various topologies have been successfully synthesized. Multinuclear multidimensional solid-state NMR techniques combined with complementary characterizations reveal the catalytic role of fluoride and the directing role of organic structure-directing agents in the synthesis process. This novel synthesis strategy not only shows excellent efficiency, but also sheds new light on the crystallization mechanism of zeolitic materials.

Summary: Functional osseoconductive coatings based on hydroxylapatite (HAp) and applied preferentially by atmospheric plasma spraying to medical implant surfaces are a key component of modern implantology. The complex reactions undergone by HAp particles in contact with a hot plasma jet alter their phase composition and crystallographic symmetry, affecting the physical and biological properties of the coatings. Surface analytical methods such as laser-Raman and nuclear magnetic resonance (NMR) spectroscopies are valuable tools for assessing structural changes in HAp caused by heat treatment during their flight along the hot plasma jet.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.
