Summary: The Mars-van Krevelen mechanism is the foundation for oxide-catalyzed oxidation reactions, and it relies on spatiotemporally separated redox steps. In this study, we demonstrate the tunability of this separation using peroxide species formed by excessively adsorbed oxygen, which modifies the catalytic activity and selectivity of the oxide. By differentiating the chemical functionality between lattice oxygen and peroxide, these results are closely relevant to a wide range of catalytic oxidation reactions using excessively adsorbed oxygen to activate lattice oxygen and tune the activity and selectivity of redox sites.

Summary: The purpose of this study was to synthesize and characterize cupric oxide nanoparticles (CuO NPs). The biosynthesis method was used to prepare CuO NPs using plant leaf extract and copper nitrate trihydrate. Various characterization techniques such as XRD, FTIR, SEM-EDS and UV-Visible Spectroscopy were used to confirm the CuO NPs. The stability, particle size, and crystal size of the CuO NPs were studied, and their suitability for cooling purposes was measured in a nanofluid.

Summary: Magnetocaloric alloys, such as LaFeMnSi, have shown potential for use in non-vapor compression cycles. The study revealed that high energy ball milling retained most of the original magnetocaloric phase in the powders, while also reducing crystallinity. Additionally, a decrease in Fe content was found to lead to a drop in the Curie temperature, with milling causing an increase in the Curie temperature by approximately 3-6 degrees Celsius.

Summary: In this study, a simple strategy was demonstrated for constructing low-tortuosity through-pores in both vertical and planar directions of electrodes by casting large particles into single-particle-layer electrodes. Through multi-scale characterizations and simulations, correlations between material/electrode structures, electrolyte permeability, polysulfide migration, and sulfur reactions were elucidated. The high-loading and dense sulfur cathode fabricated by this method delivers a high specific capacity at a very low electrolyte/sulfur ratio.

Summary: High-energy ball milling was used to modify the nanoparticle size of TiO2 and study its effects on structural, microstructural, and optical properties. Increasing milling time resulted in smaller particle sizes, broadening of X-ray diffraction peaks, decreased reflectance in UV-Vis spectra, and a decrease in bandgap transition energy. SEM analysis also showed a more homogeneous distribution of nanoparticle size with longer milling duration.

Summary: The pure and strontium substituted LaFeO3 samples were synthesized and characterized with good quality single crystals grown for dielectric and magnetic measurements. The orthorhombic structure and composition of the samples were confirmed by X-ray diffraction and energy dispersive X-ray spectroscopy analysis. The dielectric constant increased in the Sr substituted LaFeO3 crystal and magnetic properties were tested with M-H loop.

Summary: Cold sprayed commercially pure Al-based coatings were applied on Mg-based alloys at different N2 gas temperatures. The porosity percentage of the coatings decreased and the flattening ratio increased as the N2 gas temperature decreased, due to in-situ tamping densification. This resulted in a noticeable reduction in wear rate of the Al-based coatings.

Summary: An analysis of digitized 3D cement paste microstructures found a consistent size of cement grains ranging from 30-40 µm throughout hydration. The shape of the particle size distribution (PSD) remained self-similar, and the hydration process was identified to have two distinct stages, correlating with the reactivity peak of calcium sulfate.

Summary: The solid state method was used to prepare ceramic LaFeO3 nanoparticles, and the solution casting method was employed to create a nanocomposite film with polyvinyl alcohol. The film was characterized using XRD and FT-IR techniques, and it was found to be a single phase with orthorhombic crystal structure. The size of crystallites, strain, and physical parameters were determined using different methods. Additionally, the FT-IR data showed possible coulomb interactions between the polymer and ceramic.

Summary: The study on CDW in (TaSe4)2I material reveals a CDW gap of about 200 meV and shows no indication of in-gap states in the spectroscopy of CDW edge dislocation. The CDW in (TaSe4)2I is dominated by a large periodic lattice distortion instead of charge modulation.

Summary: The fabrication of Ti3SiC2 from TiC-containing reactant compacts was investigated by combustion synthesis. It was found that the addition of TiC facilitated the formation of Ti3SiC2, while excess Si and the addition of Al improved the yield and evolution of Ti3SiC2. The final products consisted primarily of Ti3SiC2, TiC, and Ti5Si3.
