Summary: By adopting the asymmetric selenium substitution strategy and using a pseudosymmetric electron acceptor, the power conversion efficiency of planar-mixed heterojunction organic solar cells (PMHJ OSCs) can be significantly improved. The increased dielectric constant and improved dimer packing lead to lower exciton binding energy, more efficient exciton dissociation, and reduced radiative recombination loss. These findings provide an effective way to develop highly efficient acceptor materials for OSCs.

Summary: Hydrogen production from water splitting using renewable electric energy is a key topic for achieving a carbon neutral future. Single atom catalysts (SACs) have emerged as a new frontier in catalysis, particularly in the hydrogen evolution reaction (HER), due to their high activity and excellent chemical selectivity. However, the influence of the neighboring coordinated atoms from the supports is often neglected in the classification of SACs. This review proposes a new classification method based on the type of supports and highlights the importance of the metal-support interaction and coordination environment. Structural designing strategies are also proposed to address the current challenges in SACs for HER.

Summary: Polymeric metal-organic framework (MOF)-derived composites are functional materials with exceptional chemical homogeneity, designable components, and adjustable pore size. This study presents the design of laminate-stacked sphere-shaped trimetallic CoNiMn-MOFs and the successful synthesis of CoNi/MnO@C composites, which exhibit excellent electromagnetic wave-absorbing performance. The modulation of oxygen and Mn vacancies through the introduction of heteroatoms and changes in annealing temperature contributes to the improvement of electromagnetic loss capacity.

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: 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.
