Acidic residues (Asp and Glu) have a high prevalence on protein surfaces, but cross‐linking reactions targeting these residues are limited. Existing methods either require high‐concentration coupling reagents or have low structural compatibility. Here a previously reported “plant‐and‐cast” strategy is extended to develop heterobifunctional cross‐linkers. These cross‐linkers first react rapidly with...
Despite incorporation of organic groups into silica‐based aerogels to enhance their mechanical flexibility, the wide temperature reliability of the modified silicone aerogel is inevitably degraded. Therefore, facile synthesis of soft silicone aerogels with wide‐temperature stability remains challenging. Herein, novel silicone aerogels containing a high content of Si are reported by using polydimethylvinylsiloxane...
Nanostructured anodes generate massive reaction sites to oxidize fuels in solid oxide fuel cells (SOFCs); however, the nonexistence of a practically viable approach for the construction of nanostructures and the retention of these nanostructures under the harsh operating conditions of SOFCs poses a significant challenge. Herein, a simple procedure is reported for the construction of a nanostructured...
2D 2H‐phase MoS2 is promising for electrocatalytic applications because of its stable phase, rich edge sites, and large surface area. However, the pristine low‐conductive 2H‐MoS2 suffers from limited electron transfer and surface activity, which become worse after their highly likely aggregation/stacking and self‐curling during applications. In this work, these issues are overcome by conformally attaching...
Investigating dendrite‐free stripping/plating anodes is highly significant for advancing the practical application of aqueous alkaline batteries. Sn has been identified as a promising candidate for anode material, but its deposition/dissolution efficiency is hindered by the strong electrostatic repulsion between Sn(OH)3− and the substrate. Herein, this work constructs a nondense copper layer which...
Two large barriers are impeding the wide implementation of electric vehicles, namely driving‐range and cost, primarily due to the low specific energy and high cost of mono‐valence cathodes used in lithium‐ion batteries. Iron is the ideal element for cathode materials considering its abundance, low cost and toxicity. However, the poor reversibility of (de)lithiation and low electronic conductivity...
2D molybdenum disulfide (MoS2) is developed as a potential alternative non‐precious metal electrocatalyst for energy conversion. It is well known that 2D MoS2 has three main phases 2H, 1T, and 1T′. However, the most stable 2H‐phase shows poor electrocatalysis in its basal plane, compared with its edge sites. In this work, a facile one‐step hydrothermal‐driven in situ porousizing of MoS2 into self‐supporting...
The development of heteroaromatic conjugated porous polymers (H‐CPPs) have received enormous research interests, because of the important functional roles of the heteroatoms in photocatalysis and proton conduction. However, due to the synthetic challenges deriving from the stable structures, the structural diversity and synthetic methods of them are still limited. Herein, a new type of H‐CPPs, covalent...
Diabetic infectious micromilieu (DIM) leads to a critical failure rate of osseointegration by virtue of two main peculiarities: high levels of topical glucose and inevitable infection. To tackle the daunting issue, a bioheterojunction‐engineered orthopedic polyetheretherketone (PEEK) implant consisting of copper sulfide/graphene oxide (CuS/GO) bioheterojunctions (bioHJs) and glucose oxidase (GOx)...
Potassium‐ion batteries (PIBs) have been regarded as a competitive alternative for lithium‐ion batteries, owing to the natural abundance, low cost, and similar rocking‐chair working mechanism of potassium element. However, it is challenging to simultaneously prepare suitable potassium ion anode materials of low voltage plateau, high capacity, and long cycle life. In this work, onion‐like soft carbon...
Implant Corrosion Protection
In article number 2106056, Yufeng Zheng, Pan Xiong, Yunsong Liu, Yongsheng Zhou, and co‐workers construct a pH stimuli‐responsive silk‐based halloysite nanotube/phytic acid self‐healing coating to slow down the corrosion rate of Mg‐1Ca alloy. The coating exhibits appealing active corrosion protection, superior biocompatibility and osteogenic ability.
Mg‐Ca alloys have emerged as a promising research direction for biomedical implants in the orthopedic field. However, their clinical use is deterred by their fast corrosion rate. In this work, a pH stimuli‐responsive silk‐halloysite (HNT)/phytic acid (PA) self‐healing coating (Silk‐HNT/PA) is constructed to slow down the corrosion rate of Mg‐1Ca alloy and its cell viability and osteogenic differentiation...
Silicon is one of the most promising anode materials for lithium‐ion batteries. However, the huge volume change of silicon during lithiation/delithiation triggers continuous growth of solid‐electrolyte interphase, loss of conductive contacts and structural collapse of the electrode, which causes a rapid deterioration of battery capacities. Inspired by the polyaromatic molecular nature and phase separation...
Piezoelectric nanomaterials open new avenues in driving green catalysis processes (e.g., H2 evolution from water) through harvesting mechanical energy, but their catalytic efficiency is still limited. The predicted enormous piezoelectricity for 2D SnSe, together with its high charge mobility and excellent flexibility, renders it an ideal candidate for stimulating piezocatalysis redox reactions. In...
Electronic structure optimization and architecture modulation are widely regarded as rational strategies to enhance the electrocatalysts catalytic performance.

In this review, the authors are primarily interested in various DNA‐based nanoprobes for miRNA...
High‐energy electrodes at high mass loadings (usually >8.0 mg cm−2) are desired for aqueous pseudocapacitors. Yet, how to overcome the thickness‐dependent resistance increase of ion/electron transport in pseudocapacitive materials is still challenging. Herein, a high‐performance electrode (denoted as AMC) adapted to high mass loading is achieved by promoting the Li‐ion affinity of 3D MoO2/carbon...
Despite the boom in the water‐triggered electric power generation technologies, few attempts have been made with a broader horizonyielding the electricity from sweat, which is of great value for low‐power‐consumption wearable electronics.

The poor electronic conductivity and low intrinsically electrocatalytic activity of most metal–organic frameworks (MOFs) greatly limit their direct applications as oxygen reduction reaction (ORR) electrocatalysts. In this work, it is reported that introduction of linker defects can effectively trigger the ORR activity of leaf‐shaped zeolitic imidazolate framework (ZIF) by increasing the intrinsic...
Poly(lactide‐co‐glycolide) (PLGA) has been widely used as a tissue engineering scaffold. However, conventional PLGA scaffolds are not injectable, and do not support direct cell encapsulation, leading to poor cell distribution in 3D. Here, a method for fabricating injectable and intercrosslinkable PLGA microribbon‐based macroporous scaffolds as 3D stem cell niche is reported. PLGA is first fabricated...
