Structured liquids in miscible fluids, due to ineffective resistance to withstand particle self‐diffusion, differ from that in immiscible liquids because of interfacial interactions. Here, a kind of structured liquid, jammed by thiol‐terminated polystyrene‐modified gold nanorods (GNRs) within tetrahydrofuran and toluene (TOL), is developed by introducing electrostatic repulsion to counterbalance the...
Perturbation of the copper (Cu) active site by electron manipulation is a crucial factor in determining the activity and selectivity of electrochemical carbon dioxide (CO2) reduction reaction (e‐CO2RR) in Cu‐based molecular catalysts. However, much ambiguity is present concerning their electronic structure–function relationships. Here, three molecular Cu‐based porphyrin catalysts with different electron...
Metal oxides with diverse compositions and structures have garnered considerable interest from researchers in various reactions, which benefits from transmission electron microscopy (TEM) in determining their morphologies, phase, structural and chemical information. Recent breakthroughs have made liquid‐phase TEM a promising imaging platform for tracking the dynamic structure, morphology, and composition...
The direct electrooxidation reaction of ammonia borane (ABOR) as the anodic reaction of direct ammonia borane fuel cells (DABFCs) is greatly dependent on the properties of electrocatalysts. Both the active sites and charge/mass transfer characteristics are the key to promoting the processes of kinetics and thermodynamics, which can further improve the electrocatalytic activity. Hence, the catalyst...
Elastomers generally possess low Young's modulus and high failure strain, which are widely used in soft robots and intelligent actuators. However, elastomers generally lack diverse functionalities, such as stimulated shape morphing, and a general strategy to implement these functionalities into elastomers is still challenging. Here, a microfluidic 3D droplet printing platform is developed to design...
Hierarchical emulsions are interesting for both scientific researches and practical applications. Hierarchical emulsions prepared by microfluidics require complicated device geometry and delicate control of flow rates. Here, a versatile method is developed to design hierarchical emulsions using microfluidic 3D droplet printing in droplet. The process of droplet printing in droplet mimics the dragonfly...
Nanozyme‐based chemodynamic therapy (CDT) has emerged as an effective cancer treatment because of its low side effects and without the requirement of exogenous energy. The therapeutic effect of CDT highlights the pivotal importance of active sites, H2O2 supplement and the glutathione (GSH) depletion of a nanozyme. The construction of a single kind of catalyst with multiple functions for the enhanced...
Hydrogel structures equipped with internal microchannels offer more in vivo‐relevant models for construction of tissues and organs in vitro. However, currently used microfabrication methods of constructing microfluidic devices are not suitable for the handling of hydrogel. This study presents a novel method of fabricating hydrogel‐based microfluidic chips by combining the casting and bonding processes...
Hydrogel microspheroids are widely used in tissue engineering, such as injection therapy and 3D cell culture, and among which, heterogeneous microspheroids are drawing much attention as a promising tool to carry multiple cell types in separated phases. However, it is still a big challenge to fabricate heterogeneous microspheroids that can reconstruct built‐up tissues' microarchitecture with excellent...
A Chinese proverb says, you can find a world in a grain of sand. Can we build complex living structures in limited sizes? In article number 1802630, Jianzhong Fu, Hongwei Ouyang, Yong He, and co‐workers report a 3D bioprinting method to build human heterogeneous organoids in microspheres, with excellent resolution and spatial organization, which has a bright future in drug screening, organ development,...
