Abstract Potassium‐ion batteries (KIBs) are very promising alternatives to lithium‐ion (LIBs) for large‐scale energy storage. However, traditional carbon anode materials usually show poor performance in KIBs due the large size of K ions. Herein, a carbonization‐etching strategy is reported making class sulfur (S) and oxygen (O) codoped porous hard microspheres (PCMs) material as novel through pyrolysis polymer (PMs) composed liquid crystal/epoxy monomer/thiol hardener system. The as‐made...

Here, we report on the effect of different antisolvent dripping film morphology and charge recombination mixed formamidinium–methylammonium tin iodide (FA0.75MA0.25SnI3) as a light absorber in perovskite solar cells. N,N-dimethyl methanamide (DMF) dimethyl sulfoxide (DMSO) were used solvent precursors together with fluoride (SnF2) an additive. Diethyl ether (DE), toluene (TL), chlorobenzene (CB) employed antisolvents for comparison. Our results show that CB leads to dense uniform Sn-based...
Atomically thin and sharp van der Waals heterojunction can be created by vertically stacking p-type monolayer tungsten diselenide (WSe2) onto n-type molybdenum disulfide (MoS2). Theory predicts that stacked MoS2 WSe2 forms type II p–n junction, creating a built-in electric field across the interface which facilitates electron–hole separation transfer. Gaining insights into dynamics of charge transfer heterostructure is central to understanding light-photocurrent conversion at these ultrathin...
Abstract A spiro‐axis skeleton not only introduces circularly polarized luminescence (CPL) into thermally activated delayed fluorescence (TADF) molecules but also enhances the intramolecular through space charge transfer (TSCT) process. Spiral distributed phenoxazine and 2‐(trifluoromethyl)‐9 H ‐thioxanthen‐9‐one‐10,10‐dioxide act as donor acceptor units, respectively. The resulting TADF enantiomers, ( rac )‐OSFSO, display emission maxima at 470 nm, small singlet‐triplet energy gap (Δ E ST )...
