The development of chiral nanostructures‐based supramolecular catalysts with satisfied enantioselectivity remains a significantly more challenging task. Herein, the synthesis and self‐assembly of various amino acid amphiphiles as chiral supramolecular catalysts after metal ion coordination is reported and systematically investigate their enantioselectivity in asymmetric Diels–Alder reactions. In particular,...
High entropy materials offer almost unlimited catalytic possibilities due to their variable composition, unique structure, and excellent electrocatalytic performance. However, due to the strong tendency of nanoparticles to coarsen and agglomerate, it is still a challenge to synthesize nanoparticles using simple methods to precisely control the morphology and size of the nanoparticles in large quantities,...
pH‐dependent peptide biomaterials hold tremendous potential for cell delivery and tissue engineering.

Solution‐processed and efficient yellow quantum dot light‐emitting diodes (QLEDs) are considered key optoelectronic devices for lighting, display, and signal indication. However, limited synthesis routes for yellow quantum dots (QDs), combined with inferior stress‐relaxation of the core–shell interface, pose challenges to their commercialization.

The hydrogen evolution reaction (HER) activity of defect‐stabilized low‐Pt‐loading catalysts is closely related with defect type in support materials, while the knowledge about the effect of higher‐dimensional defects on the property and activity of trapped Pt atomic species is scarce. Herein, small size (5–10 nm) TiO2 nanoparticles with abundant surface step defects (one kind of line defect) are...
Due to the shortage of pure water resources, seawater electrolysis is a promising strategy to produce green hydrogen energy. To avoid chlorine oxidation reactions (ClOR) and the production of more corrosive hypochlorite, enhancing OER electrocatalyst activity is the key to solving the above problem. Considering that transition metal phosphides (TMPs) are promising OER eletrocatalysts for seawater...
Organic compounds are regarded as important candidates for potassium‐ion batteries (KIBs) due to their light elements, controllable polymerization, and tunable functional groups. However, intrinsic drawbacks largely restrict their application, including possible solubility in electrolytes, poor conductivity, and low diffusion coefficients. To address these issues, an ultrathin layered pyrazine/carbonyl‐rich...
Artificial solid electrolyte interphase in organic solutions is effective and facile for long‐cycling aqueous zinc ion batteries.

Efficient bifunctional hydrogen electrocatalysis, encompassing both hydrogen evolution reaction (HER) and hydrogen oxidation reaction (HOR), is of paramount significance in advancing hydrogen‐based societies. While non‐precious‐metal‐based catalysts, particularly those based on nickel (Ni), are essential for alkaline HER/HOR, their intrinsic catalytic activity often falls short of expectations. Herein,...
Structure engineering of magnetic‐dielectric multi‐components is emerging as an effective approach for presuming high‐performance electromagnetic (EM) absorption, but still faces bottlenecks due to the ambiguous regulation mechanism of surface morphology.

Interface engineering attracted tremendous attention owing to its remarkable ability to impede dendrite growth and side reactions in aqueous zinc‐ion batteries. Artificial interface layers composed of crystalline materials have been extensively employed to stabilize the Zn anode. However, the diffusion kinetics of Zn2+ in highly crystalline materials are hindered by steric effects from the lattice,...
