Summary: This study presents the design of carbon heterostructures derived from bamboo, which exhibit excellent electromagnetic absorption performance and environmental adaptability. The assembly of nanofibers and nanosheets acts as a nanometer-sized antenna, enhancing the conductive loss. The composition of cellulose and lignin in the precursor significantly affects the assembly shape, the formation of covalent bonds, and the surface hydrophobicity. The obtained carbon heterostructure maintains wideband electromagnetic absorption in real-world environments.

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: With the rapid development of fifth-generation mobile communication technology and wearable electronic devices, the need for highly efficient EMI shielding materials has become crucial. In this study, a three-dimensional graphene oxide (GO) with regular honeycomb structure (GH) was constructed using sacrificial template and freeze-drying methods. Amino functionalized FeNi alloy particles (f-FeNi) were loaded onto the GH skeleton followed by in-situ reduction to prepare rGH@FeNi aerogel. The resulting rGH@FeNi/epoxy composites with a low rGH@FeNi mass fraction of 2.1 wt% exhibited a high EMI shielding effectiveness (EMI SE) of 46 dB, which is 5.8 times higher than that of rGO/FeNi/epoxy composites with the same mass fraction. The composites also displayed excellent thermal stability and mechanical properties.

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.
