Abstract Two‐dimensional (2D) materials are promising candidates for advanced water purification membranes. A new kind of lamellar membrane is based on a stack 2D MXene nanosheets. Starting from compact Ti 3 AlC 2 , delaminated nanosheets the composition C T x with functional groups (O, OH, and/or F) can be produced by etching and ultrasonication stapled porous support vacuum filtration.

Wireless sensor networks (WSNs) have attracted substantial research interest, especially in the context of performing monitoring and surveillance tasks. However, it is challenging to strike compelling trade-offs amongst various conflicting optimization criteria, such as network's energy dissipation, packet-loss rate, coverage lifetime.

Halogenation of terminal acceptors has been shown to give dramatic improvements in power conversion efficiencies (PCEs) organic solar cells (OSCs). Similar significant results could be expected from the halogenation central units state-of-the-art Y-series acceptors. Herein, a pair acceptors, termed CH6 and CH4, featuring conjugation-extended phenazine unit with without fluorination, have synthesized. The fluorinated enhanced molecular interactions crystallinity, superior fibrillar network...
Abstract Given that bromine possesses similar properties but extra merits of easily synthesizing and polarizing comparing to homomorphic fluorine chlorine, it is quite surprising very rare high-performance brominated small molecule acceptors have been reported. This may be caused by undesirable film morphologies stemming from relatively larger steric hindrance excessive crystallinity bromides. To maximize the advantages bromides while circumventing weaknesses, three (CH20, CH21 CH22) are...
The diverse molecular stacking tuned by peripheral halogens in non-fullerene acceptors (NFAs) significantly affects the physicochemical properties, film morphologies and thus power conversion efficiencies (PCEs) of organic solar cells (OSCs).

Among these, acceptor CH-BBQ, embedded with benzobisthiadiazole, exhibited an optimal fibrillar network morphology,...
2D Ruddlesden-Popper (2D RP) perovskite, with attractive environmental and structural stability, has shown great application in perovskite solar cells (PSCs).

Consequently, CH23‐based binary OSC reaches...
Abstract Molecular innovation is highly desirable to achieve efficient all‐small‐molecule organic solar cells (SM‐OSCs). Herein, three small‐molecule donors (SMDs) with alkylated thiazole side groups (namely BO‐1, HD‐1, and OD‐1), which differ only in the alkyl chain are reported. Although these SMDs possess similar absorption profiles molecular energy levels, their crystallinity miscibility BTP‐eC9 slightly decrease along elongation of chain. After blending BTP‐eC9, different leads degrees...
