Active layer morphology is of vital importance for the photovoltaic performance of organic solar cells (OSCs). As fullerene derivatives and nonfullerene acceptors are highly complementary in many aspects, fullerene derivatives as a third component in nonfullerene OSCs could tune the blend morphology and improve the power conversion efficiency (PCE). Relative to PCBM, the indene-C60 bisadduct (ICBA) as the third component in nonfullerene binary OSCs has not been extensively studied.

Modular components for rapid assembly of microfluidics must put extra effort into solving leakage and alignment problems between individual modules. Here, we demonstrate a conductive elastomer with self-healing properties and propose a modular microfluidic component configuration system that utilizes self-healing without needing external interfaces as an alternative to the traditional chip form. Specifically, dual dynamic covalent bond crosslinks (imine and borate ester bonds) established between Polyurethane (PU) and 2-Formylbenzeneboronic acid (2-FPBA) are the key to a hard room-temperature self-healing elastomeric substrate PP (PU/2-FPBA).

Exploring the application of high-efficiency bifunctional oxygen catalysts to rechargeable zinc-air batteries has been a research hotspot in recent years. We succeeded in obtaining NiCo NS with a hollow capsule structure through the self-sacrificing template method, which has a larger specific surface area and can provide more active sites for electrocatalysis relative to his solid. The introduction of S can change the valence distribution of N and the electronic structure of the M-N bond, so that NiCo NS exhibits excellent performance in the overpotential and stability of the oxygen reduction and oxygen evolution reactions.

FAM107A may have a dual role in regulating the biological functions of tumors; however, its role in prostate adenocarcinoma (PRAD) remains unknown. We analyzed FAM107A expression by employing databases to clarify its potential prognostic value for PRAD, as well as its role in the pathogenesis of PRAD. We observed that the FAM107A expression level is decreased in PRAD, and the reduced expression is considerably associated with poor overall survival and progression-free survival (PFS).
