As the most popular liquid metal (LM), gallium (Ga) and its alloys are emerging as functional materials due to their unique combination of fluidic and metallic properties near room temperature. As an important branch of utilizing LMs, micro‐ and submicron‐particles of Ga‐based LM are widely employed in wearable electronics, catalysis, energy, and biomedicine. Meanwhile, the phase transition is crucial...
Adhesive gels derived from biobased sustainable materials have extremely broad application prospects, such as in flexible smart materials and biomedicine fields. Combining high toughness and strong, persisting repeatable adhesion has always been a daunting challenge for adhesive gels. However, bulk gels based on polysaccharides as the most abundant bio‐based compounds usually possess a high toughness...
Advanced materials with aligned cellulose nanocrystals (CNCs) have attracted much attention due to their remarkable mechanical and optical properties, but most of them still focus on 1D or 2D architectures. Herein, complex 3D architectures as pseudo catenoid hollow xerogels with aligned CNCs are prepared from dynamic hydrogels by mechanical stretching and air‐drying process. Aligned CNCs endow the...
The search for earth‐abundant, low‐cost, recyclable, multifunctional as well as highly active catalysts remains the most pressing demand for heterogeneous catalytic elimination of pollutants in water environment remediation. Herein, a porous graphitic carbon‐encapsulated Ni nanoparticles (NPs) hybrid (Ni@GC) is designed/constructed by direct pyrolysis of a Ni‐based metal−organic framework (MOF) in...
Carbon nanofibers (CNF) with a 1D porous structure offer promising support to encapsulate transition‐metal oxides in energy storage/conversion relying on their high specific surface area and pore volume. Here, the preparation of NiO nanoparticle‐dispersed electrospun N‐doped porous CNF (NiO/PCNF) and as free‐standing film electrode for high‐performance electrochemical supercapacitors is reported....
A simple strategy for the synthesis of heteroatom‐doped porous carbon materials (CMs) via using ionic liquid (IL)‐doped alkali organic salts as small molecular precursors is developed. Doping of alkali organic salts (such as sodium glutamate, sodium tartrate, and sodium citrate) with heteroatoms containing ILs (including 1‐butyl‐3‐methylimidazolium chlorine and 3‐butyl‐4‐methythiazolebromination)...
