IrO2 as benchmark electrocatalyst for acidic oxygen evolution reaction (OER) suffers from its low activity and poor stability. Modulating the coordination environment of IrO2 by chemical doping is a methodology to suppress Ir dissolution and tailor adsorption behavior of active oxygen intermediates on interfacial Ir sites. Herein, the Re‐doped IrO2 with low crystallinity is rationally designed as...
Developing orthogonal chemical communication pathways in diverse synthetic cell communities is a considerable challenge due to the increased crosstalk and interference associated with large numbers of different types of sender‐receiver pairs. Herein, the authors control which sender‐receiver pairs communicate in a three‐membered community of synthetic cells through red and blue light illumination...
Heparin is a commonly applied blood anticoagulant agent in clinical use. After treatment, excess heparin needs to be removed to circumvent side effects and recover the blood‐clotting cascade. Most existing heparin antidotes rely on direct heparin binding and complexation, yet selective compartmentalization and sequestration of heparin would be beneficial for safety and efficiency. However, such systems...
In this study, to visually acquire all‐round structural and functional information of lung cancer while performing synergistic photothermal therapy (PTT) and tumor‐targeting immunotherapy, a theranostic nanoplatform that introduced upconversion nanoparticles (UCNPs) and IR‐1048 dye into the lipid‐aptamer nanostructrure (UCILA) is constructed. Interestingly, the IR‐1048 dye grafted into the lipid bilayer...
GaTe has recently attracted significant interest due to its direct bandgap and unique phase structure, which makes it a good candidate for optoelectronics. However, the controllable growth of large‐sized monolayer and few‐layer GaTe with tunable phase structures remains a great challenge. Here the controlled growth of large‐sized GaTe with high quality, chemical uniformity, and good reproducibility...
The atomic structure of free‐standing graphene comprises flat hexagonal rings with a 2.5 Å period, which is conventionally considered the only atomic period and determines the unique properties of graphene. Here, an unexpected highly ordered orthorhombic structure of graphene is directly observed with a lattice constant of ≈5 Å, spontaneously formed on various substrates. First‐principles computations...
In article number 1902637, Guosheng Shi, Yi Zhang, and co‐workers discover an orthorhombic crystal of graphene with an ≈5 Å period formed on various substrates, which can be applied to control the epitaxial self‐assembly of amyloid peptides. First‐principle computations show that this atomic structure can be attributed to dipoles between the graphene surface and substrates.
Rechargeable magnesium batteries (rMBs) are promising as the most ideal further energy storage systems but lack competent cathode materials due to sluggish redox reaction kinetics. Herein, developed is an anionic Se‐substitution strategy to improve the rate capability and the cycling stability of 2D CuS1−xSex nanosheet cathodes through an efficient microwave‐induced heating method. The optimized CuS...
