Due to its tumor homing and long serum half‐life, albumin is an ideal drug carrier for chemotherapy. For endogenous albumin hitchhiking with high cargo loading, a trimeric albumin‐binding domain (ABD), i.e., ABD‐Tri is designed by fusing an ABD with high specificity and affinity for albumin to a self‐trimerizing domain (Tri) with an additional cysteine residue. ABD‐Tri is highly (40 mg L−1) expressed...
The rational design of metal–organic framework (MOF)‐based electrocatalysts plays a key role in achieving high‐efficiency oxygen evolution reaction (OER). Herein, a synergetic morphology and electronic structure engineering strategy are proposed to design a Co‐MOF nanoflower grown on carbon paper via rare‐earth cerium doping (CoCe‐MOF/CP). Compared with Co‐MOF/CP, the developed CoCe‐MOF/CP exhibited...
Borophene, a promising material with potential applications in electronics, energy storage, and sensors, is successfully grown as a monolayer on Ag(111), Cu(111), and Au(111) surfaces using molecular beam epitaxy. The growth of two‐dimensional borophene on Ag(111) and Au(111) is proposed to occur via surface adsorption and boron segregation, respectively. However, the growth mode of borophene on Cu(111)...
Mesoporous silica nanoparticles (MSNs) have been widely praised as nanoadjuvants in vaccine/tumor immunotherapy thanks to their excellent biocompatibility, easy‐to‐modify surface, adjustable particle size, and remarkable immuno‐enhancing activity. However, the application of MSNs is still greatly limited by some severe challenges including the unclear and complicated relationships of structure and...
Structurally optimized transition metal phosphides are identified as a promising avenue for the commercialization of lithium–sulfur (Li–S) batteries. In this study, a CoP nanoparticle‐doped hollow ordered mesoporous carbon sphere (CoP‐OMCS) is developed as a S host with a “Confinement–Adsorption–Catalysis” triple effect for Li–S batteries. The Li‐S batteries with CoP‐OMCS/S cathode demonstrate excellent...
The purification of C2H4 from C2H6/C2H4/C2H2 mixtures is of great significance in the chemical industry for C2H4 production but remains a daunting task.

The electrochemical performance of SiOx/C anode is affected by the match of their working potentials. In article number 2302644, Shang Wang, Yanhong Tian, Andreu Cabot, Lijie Ci, and co‐workers demonstrate that a bidirectional diffusion behavior exists in SiOx/graphite anode due to the working potential mismatch, deteriorating the cycle life of the electrode. This mismatch can...
Silicon oxide (SiOx), inheriting the high‐capacity characteristic of silicon‐based materials but possessing superior cycling stability, is a promising anode material for next‐generation Li‐ion batteries. SiOx is typically applied in combination with graphite (Gr), but the limited cycling durability of the SiOx/Gr composites curtails large‐scale applications. In this work, this limited durability is...
Post‐combustion flue gas (mainly containing 5–40% CO2 balanced by N2) accounts for about 60% global CO2 emission. Rational conversion of flue gas into value‐added chemicals is still a formidable challenge. Herein, this work reports a β‐Bi2O3‐derived bismuth (OD‐Bi) catalyst with surface coordinated oxygen for efficient electroreduction of pure CO2, N2, and flue gas. During pure CO2 electroreduction,...
To reveal how the size effect and strain effect synergistically regulate the mass activity (MA) and specific activity (SA) of Pt alloy nanocrystal catalysts in oxygen reduction reaction (ORR), remains to be difficult due to the highly entangled factors.
