Summary: This study developed a simple, eco-friendly, effective, and low-cost method for the large-scale fabrication of cesium tungsten bronze (Cs0.32WO3) nanomaterials. The proposed ball-milling process reduced tungstic acid to hydro tungsten bronze (HxWO3) and incorporated cesium ions (Cs+) until the formation of Cs0.32WO3. The obtained Cs0.32WO3 nanoparticles were dispersed in a solution composed of surfactant and polymer, which could form a thin film on a glass substrate with high visible light transmittance and excellent NIR-shielding capability.

Summary: Tungsten-based catalysts, including WO3 and H2WO4, can selectively cleave C-C bonds in sugar intermediates during the conversion of cellulose to ethylene glycol and propylene glycol. The catalysts undergo reduction to HxWO3 species during the reaction, which act as heterogeneous catalysts and are re-oxidized to WO3 upon exposure to ambient air after the reaction. The activity of WO3 is strongly dependent on its crystallite size and surface area.

Summary: Designing efficient catalysts is a crucial challenge for practical applications of high-capacity hydride in fuel-cell-based hydrogen economy. In this study, platinum-functionalized Ti3C2 material with an accordion-like structure, interlayer, and surface-dispersed nanoparticles was synthesized. The catalyst, Ti3C2@Pt, reduced the initial dehydrogenation temperature of high-density hydride AlH3 by 50% to 62 °C, comparable to commercial AlH3. Moreover, it exhibited high hydrogen supplying performance and retention ratio, achieving 9.3 wt% and 98% respectively, surpassing previously reported catalysts. The exceptional dehydrogenation performance of the material makes it a practical candidate for mobile device applications with the aid of high-efficiency catalysts.

Summary: A generalized method is proposed to fabricate oxide wrinkles on liquid metal surfaces with multi-scale and diverse dimensional hierarchies. By altering the substrate geometry, the distribution of growth stress is changed, leading to different wrinkle morphologies such as one-dimensional stripes and two-dimensional labyrinths. Furthermore, radial wrinkles are obtained under hoop stress induced by surface tension difference. These hierarchical wrinkles of different scales can coexist on the liquid metal surface. Wrinkles on liquid metal surfaces may have potential applications in flexible electronics, sensors, displays, etc.

Summary: The experimental phenomenon of spinning liquid metal droplets on an ice block is discovered, which involves the dual solid-liquid phase transition of the liquid metal and the ice. Comparative experiments clarify that the circumferential driving force comes from the escaping bubbles as the ice melts. Furthermore, it is found that the spin effect can be universal for objects of different materials, as long as the two necessary elements of rapid liquid film establishment and gas bubble release can be satisfied simultaneously.

Summary: This paper presents the creation of biotissue-like agglomerates using water and liquid metals, which display versatile rhythmic behaviors. The agglomerates are capable of floating intact in solution and exhibit rhythmic variations in physical properties. This is attributed to the reversible redox behaviors ignited by bioelectrical signals. Further experiments reveal the roles of liquid matter in the formation and rhythmic capabilities of the agglomerates. This research offers a universal paradigm for simulating the rhythmic behaviors of biological tissues using inorganic systems, acting as a starting point for bridging artificial matter with natural biotissues.
