Summary: We have developed cerium oxide (CeO2) nanoparticles with trace amounts of platinum oxide (PtO) anchored on their surfaces for photocatalytic degradation of atrazine (AZ) in water. Characterization by various techniques confirmed the growth of PtO nanoparticles on CeO2 nanocubes. The introduction of PtO widened the visible-light absorption of the CeO2, resulting in a bandgap of 2.20 eV. The PtO/CeO2 catalyst with a concentration of 0.9% PtO was able to mineralize AZ with a rate constant of 82.82 x 10-3 min-1, and it exhibited excellent reusability with 97% retention of activity.

Summary: This study demonstrates that utilizing steric hindrance in metal-organic polyhedra on the outer surface can be an effective way to separate pyridine-based regioisomers through liquid-liquid extraction, resulting in highly pure compounds. The differential solubility of bound and non-bound pyridine regioisomers was exploited to engineer liquid-liquid self-sorting systems, successfully separating equimolecular mixtures of regioisomers.

Summary: This study demonstrates the interface state-dependent artificial synaptic characteristics of Pt/CeO2/Pt memristors controlled by post-deposition annealing of CeO2 layer. The resistance change simulates wide-range, linear, and symmetric potentiation and depression behaviors, and the conduction modes are well matched with Schottky conduction controlled by interface energy barrier. The results highlight the importance of interface control for reliable synaptic operations.

Summary: Interfacial crosslinking is a useful method for preparing films with desired structures. In this study, a crosslinked film (Rc-mProdot) with loose structure was successfully obtained from a linear polymer (mProdot) via liquid/liquid interfacial crosslinking. The Rc-mProdot film exhibited improved electrochromic and capacitance properties compared to the spin-coated mProdot polymer film.

Summary: This study aimed to prepare bimetallic composites using a liquid-liquid compound casting method and investigated the interface evolution with an increase in the pouring time interval. It was found that melt mixing occurred at a pouring interval of 3 s. A transition zone appeared at the interface with a pouring interval of 10 s, resulting in a good metallurgical bond. However, a discontinuous oxide layer formed at the interface with a pouring interval of 20 s, providing a pathway for the transport of SiC particles.

Summary: Bimetallic Pt-Pd catalysts supported on ceria show improved performance in wet conditions, possibly due to the formation of unique mushroom-like structures resulting from the alloying of Pt and Pd. Catalyst prepared by milling Pd metal and ceria first, followed by the addition of Pt, exhibits better performance compared to conventional impregnated samples.

Summary: The interface structure of Cu30Cr0.2Zr electrical contacts was modified using CeO2/GO to improve mechanical properties and arc erosion resistance. The addition of CeO2/GO enhanced the tensile strength, ductility, and electrical conductivity of the composites. It also reduced the concentrated erosion of the arc, improved welding resistance, and prolonged the electrode's service life.

Summary: In this study, Raman spectroscopy and scanning microwave impedance microscopy were used to investigate the internal stress and relative permittivity of BaTiO3 nanocube three-dimensional assemblies under different heat treatment temperatures. The results show that heat treatment caused internal compressive stress in the nanocube assemblies and a positive correlation between the internal compressive stress and relative permittivity.
