Fused-ring electron acceptors have made significant progress in recent years, while the development of fully non-fused ring has been unsatisfactory. Here, two acceptors, o-4TBC-2F and m-4TBC-2F, were designed synthesized. By regulating location hexyloxy chains, formed planar backbones, m-4TBC-2F displayed a twisted backbone. Additionally, film showed markedly red-shifted absorption after thermal annealing, which indicated formation J-aggregates. For fabrication organic solar cells (OSCs),...

Abstract Abdominal and intrauterine adhesions are common postoperative problems that can cause serious complications. Current adhesives usually double sided suffer from poor wet adhesion, nondegradability, monofunctionality, which limits their application in preventing adhesions. Herein, a bioinspired microstructured Janus bioadhesive, named OD/GM@PG, with adhesive inner layer an antiadhesive outer is prepared by combining electrostatic spun materials. By using both capillary suction...

Most current distributed machine learning systems try to scale up model training by using a data-parallel architecture that divides the computation for different samples among workers. We study from motivation, where information about same samples, e.g., users and objects, are owned several parities wish collaborate but do not want share raw data with each other.
Wound dressings with asymmetric wettability surfaces can effectively prevent bacterial colonization and tissue dehydration have shown great potential for diabetic wound healing applications. However, the construction of a highly hydrophobic outer surface high biocompatibility permeability is still major challenge in preparation wettable dressings. Inspired by superhydrophobic structures existing nature, an composite dressing layer was successfully prepared this study. The fabricated...
Abstract 2D Ruddlesden–Popper perovskites (RPPs) are emerging as potential challengers to their 3D counterpart due superior stability and competitive efficiency.
