Interface modification plays an important role in improving the power conversion efficiency (PCE) of organic solar cells (OSCs). However, the low non‐covalent interaction between the cathode interface layer (CIL) and nonfullerene acceptor (NFA) directly affects the charge collection of OSCs. Here, the non‐covalent interaction between the CIL and NFA is enhanced by introducing the 2D vermiculite (VML)...
Rechargeable aqueous aluminum batteries (AABs) are promising energy storage technologies owing to their high safety and ultra‐high energy‐to‐price ratio. However, either the strong electrostatic forces between high‐charge‐density Al3+ and host lattice, or sluggish large carrier‐ion diffusion toward the conventional inorganic cathodes generates inferior cycling stability and low rate‐capacity. To overcome...
Bio‐electrochemical conversion of anthropogenic CO2 into value‐added products using cost‐effective metal‐free catalysts represents a promising strategy for sustainable fuel production. Herein, N‐doped carbon nanosheets synthesized via pyrolysis of the zeolitic‐imidazolate framework (ZIF) are developed for constructing efficient biohybrids to facilitate CO2‐to‐CH4 conversion. The microbial enrichment...
That magic‐size clusters (MSCs) have their counterpart precursor compounds (PCs) has not been generally accepted by expertise circles. Here, experimental evidence to support this new concept is presented. With aqueous‐phase CdSe MSCs as a model system, it is shown that when the MSCs are dispersed in water containing a certain amount of L‐cysteine (Cys), the MSCs disappear slowly. Upon the addition...
Halide perovskites exhibit outstanding optoelectronic properties, which make them an ideal choice for photocatalytic CO2 reduction and benzyl alcohol (BA) oxidation. Nevertheless, the simultaneous realization of the above redox coupling reactions on halide perovskites remains a great challenge, as it requires distinct catalytic sites for different target reactions. Herein, the catalytic sites of Cs...
Perovskite solar cells have rapidly developed as a promising technology for the next generation of low‐cost photovoltaics, receiving enormous attention from researchers and industries. Compared to traditional semiconducting materials, metal halide perovskite exhibits outstanding tolerance to extrinsic ions. At a certain range of doping concentration, the interstitial occupancy of extrinsic ions provides...
Perovskite nanocrystals (PNCs) are promising candidates for solar‐to‐fuel conversions yet exhibit low photocatalytic activities mainly due to serious recombination of photogenerated charge carriers. Constructing heterojunction is regarded as an effective method to promote the separation of charge carriers in PNCs. However, the low interfacial quality and non‐directional charge transfer in heterojunction...
Chemoradiotherapy (CRT) is the most accepted treatment for locally advanced pancreatic ductal adenocarcinoma (PDAC) and can significantly improve the R0 resection rate. However, there are few long‐term survivors after CRT. Although some polymer nanoparticles have shown potential in alleviating the dose‐limiting toxicity and assisting the chemotherapy of PDAC, there are few efficient nanosensitizers...
Selective hydrogenation and hydrodeoxygenation (HDO) of biomass to value‐added products play a crucial role in the development of renewable energy resources. However, achieving a temperature‐controlled selectivity within one catalytic system while retaining excellent hydrogenation and HDO performance remains a great challenge. Here, nitrogen/oxygen (N/O) co‐doped porous carbon nanosphere derived from...
Suitable anode materials with high capacity and long cycling stability, especially capability at high current densities, are urgently needed to advance the development of potassium ion batteries (PIBs) and sodium ion batteries (SIBs). Herein, a porous Ni‐doped FeSe2/Fe3Se4 heterojunction encapsulated in Se‐doped carbon (NF11S/C) is designed through selenization of MOFs precursor. The porous composite...
Nowadays, nearly 48.7% near‐infrared (NIR) irradiation (>800 nm) of the full solar spectrum has actually not been fully utilized since the state‐of‐the‐art perovskite film usually can only absorb the most UV–vis sunlight radiation. Herein, high efficiency integrated Cs0.15FA0.85PbI3 perovskite/organic bulk (PC61BM:D18:Y6) heterojunction solar cells with enhanced low energy photon harvest until...

The preparation of a type of innovative cationic copolypeptoid antimicrobials containing various hydrophobic moieties that resemble both structure and membrane‐lytic antibacterial mechanism of natural antimicrobial peptides (AMPs) is reported. By finely tuning the hydrophilic/hydrophobic balance, the polypeptoids exhibit a wide spectrum of antibacterial activity against both Gram‐positive bacteria...
Iron–nitrogen–carbon materials (Fe–N–C) are known for their excellent oxygen reduction reaction (ORR) performance. Unfortunately, they generally show a laggard oxygen evolution reaction (OER) activity, which results in a lethargic charging performance in rechargeable Zn–air batteries. Here porous S‐doped Fe–N–C nanosheets are innovatively synthesized utilizing a scalable FeCl3‐encapsulated‐porphyra...
Quantum dots light‐emitting diodes (QLEDs) have attracted much interest owing to their compatibility with low‐cost inkjet printing technology and potential for use in large‐area full‐color pixelated display. However, it is challenging to fabricate high efficiency inkjet‐printed QLEDs because of the coffee ring effects and inferior resistance to solvents from the underlying polymer film during the...
