With the development of electric vehicles, exploiting anode materials with high capacity and fast charging capability is an urgent requirement for lithium‐ion batteries (LIBs). Borophene, with the merits of high capacity, high electronic conductivity and fast diffusion kinetics, holds great potential as anode for LIBs. However, it is difficult to fabricate for the intrinsic electron‐deficiency of...
The direct use of mesenchymal stem cells (MSCs) as therapeutics for skin injuries is a promising approach, yet it still faces several obstacles, including limited adhesion, retention, and engraftment of stem cells in the wound area, as well as impaired regenerative and healing functions. Here, DNA‐based self‐assembled composites are reported that can aid the adhesion of MSCs in skin wounds, enhance...
Fiber crossbars, an emerging electronic device, have become the most promising basic unit for advanced smart textiles. The demand for highly sensitive fiber crossbar sensors (FCSs) in wearable electronics is increased. However, the unique structure of FCSs presents challenges in replicating existing sensitivity enhancement strategies. Aiming at the sensitivity of fiber crossbar sensors, a second‐order...
PbS quantum dot (QD) solar cells harvest near‐infrared solar radiation. Their conventional hole transport layer has limited hole collection efficiency due to energy level mismatch and poor film quality. Here, how to resolve these two issues by using Ag‐doped PbS QDs are demonstrated. On the one hand, Ag doping relieves the compressive stress during layer deposition and thus improves film compactness...
Nuclear energy holds great potential to facilitate the global energy transition and alleviate the increasing environmental issues due to its high energy density, stable energy output, and carbon‐free emission merits. Despite being limited by the insufficient terrestrial uranium reserves, uranium extraction from seawater (UES) can offset the gap. However, the low uranium concentration, the complicated...
pH‐dependent peptide biomaterials hold tremendous potential for cell delivery and tissue engineering.

In this work, An experimental procedure based on the one‐bead one‐compound (OBOC) combinatorial library is developed to rapidly screen self‐assembling β‐sheet peptides at neutral...
Developing a highly active, durable, and low‐platinum‐based electrocatalyst for the cathodic oxygen reduction reaction (ORR) is for breaking the bottleneck of large‐scale applications of proton exchange membrane fuel cells (PEMFCs). Herein, ultrafine PtZn intermetallic nanoparticles with low Pt‐loading and trace germanium (Ge) involvement confined in the nitrogen‐doped porous carbon (Ge‐L10‐PtZn@N‐C)...
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...

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,...
