Summary: Chemodynamic therapy (CDT) is a novel cancer treatment strategy that generates hydroxyl radicals in the tumor region using Fenton or Fenton-like reactions. It has advantages such as low side effects, independence from external stimulation, modulation of the tumor microenvironment, and low treatment cost. CDT can also be combined with other therapies to enhance anticancer effects.

Summary: In this work, the performance of c-Si/ZnO heterojunction ultrathin-film solar cells is enhanced by an integrated structure of c-Si trapezoidal pyramids on the top and Al pyramids in the active layer. The top c-Si pyramid increases absorption of short wavelengths and the bottom Al pyramid improves overall optical absorption, resulting in a high absorption rate of 93.16%. The optimized current density and conversion efficiency of the solar cells are 41.94 mA cm(-2) and 18.97%, respectively. The solar cells show good absorption in a wide range of incident angles and the electric field intensity profile demonstrates excellent light-trapping performance.

Summary: In this study, CdS nanowires were combined with vanadium carbide using a specific method, and it was found that the photocatalytic activity of the CdS nanowires was significantly enhanced when loaded with vanadium carbide, especially for simultaneous production of H2 and selective oxidation of benzyl alcohol into benzaldehyde. Additionally, the vanadium carbide loading also reduced the recombination rate of hydrogen and benzaldehyde. The results of this study demonstrate the importance of this method in achieving commercialization of photocatalytic hydrogen production.

Summary: Developing durable photocatalysts for efficient antibiotics degradation is crucial for environmental purification. In this study, hierarchical organic-inorganic TCPP/Bi2MoO6 heterojunctions were successfully synthesized and showed superior photocatalytic performance in the visible light degradation of tetracycline hydrochloride. The high catalytic activity was attributed to the interfacial interaction between TCPP and Bi2MoO6, which facilitated charge carrier separation and enhanced visible-light absorbance.

Summary: This study introduces a highly emissive molecule with enhanced quenching resistance by segregating the planar MR-TADF skeleton using two bulky carbazolyl units, which significantly improves the performance of corresponding devices with a maximum external quantum efficiency of 40.0% and a full width at half maximum of 25 nm.
The steric effect of the bulky carbazolyl units largely removes the formation of detrimental excimers/aggregates, leading to an OLED example that can achieve narrow bandwidth and high EL efficiency surpassing 40% to date.

Summary: Recent research has shown that not only the solid-electrolyte interphase (SEI) layer but also the metal-ion solvation structure and interfacial model in the electrolyte significantly affect the performance of lithium-ion batteries. In this paper, the authors summarize recent studies on the importance of electrolyte solvation structure, develop a quantitative model, and propose an interfacial model to understand the electrode's performance. These findings may lead to a new era beyond the SEI and have implications for the design and improvement of LIBs.
