All‐hydrogel supercapacitors are emerging as promising power sources for next‐generation wearable electronics due to their intrinsic mechanical flexibility, eco‐friendliness, and enhanced safety. However, the insufficient interfacial adhesion between the electrode and electrolyte and the frozen hydrogel matrices at subzero temperatures largely limit the practical applications of all‐hydrogel supercapacitors...
Ensuring an appropriate nitrite level in food is essential to keep the body healthy. However, it still remains a huge challenge to offer a portable and low‐cost on‐site food nitrite analysis without any expensive equipment. Herein, a portable integrated electrochemical sensing system (IESS) is developed to achieve rapid on‐site nitrite detection in food, which is composed of a low‐cost disposable...
Although 2D π‐d conjugated metal–organic frameworks (MOFs) exhibit high in‐plane conductivity, the closely stacked layers result in low specific surface area and difficulty in mass transfer and diffusion. Hence, a conductive 3D MOF Fe3(HITP)2/bpm@Co (HITP = 2,3,6,7,10,11‐hexaiminotriphenylene) is reported through inserting bpm (4,4′‐bipyrimidine) ligands and Co2+ into the interlayers of 2D MOF Fe3...
The increasing demand for graphite and the higher lithium content than environment abundance make the recycling of anode in spent lithium‐ion batteries (LIBs) also become an inevitable trend.

After the oxidation and intercalation by FeCl3 for the retired graphite, H...
Integrating single atoms and clusters into one system represents a novel strategy for achieving the desired catalytic performance. In comparison to single‐atom catalysts, catalysts combining single atoms and clusters harness the advantages of both, thus displaying greater potential. Nevertheless, constructing single‐atom‐cluster systems remains challenging, and the fundamental mechanism for enhancing...
