Atomic‐scale interface engineering is a prominent strategy to address the large volume expansions and sluggish redox kinetics for reinforcing K‐storage. Here, to accelerate charge transport and lower the activation energy, dual carbon‐modified interfacial regions are synthesized with high lattice‐matching degree, which is formed from a CoSe2/FeSe2 heterostructure coated onto hollow carbon fibers....
Mn‐based layered oxide is extensively investigated as a promising cathode material for potassium‐ion batteries due to its high theoretical capacity and natural abundance of manganese. However, the Jahn–Teller distortion caused by high‐spin Mn3+(t2g3eg1) destabilizes the host structure and reduces the cycling stability. Here, K0.02Na0.55Mn0.70Ni0.25Zn0.05O2 (denoted as KNMNO‐Z) is reported to inhibit...
Potassium‐ion battery represents a promising alternative of conventional lithium‐ion batteries in sustainable and grid‐scale energy storage. Among various anode materials, elemental phosphorus (P) has been actively pursued owing to the ideal natural abundance, theoretical capacity, and electrode potential. However, the sluggish redox kinetics of elemental P has hindered fast and deep potassiation...
This work reports a portable, origami‐type paper device with a plasmonic fluor‐labeled microneedle sensing module for the multiplexed quantification of anemia biomarkers in whole blood. Sequential steps, including serum separation, target enrichment, and multiplexed readout by a gel imager, are rapidly accomplished with the flexible and highly integrated device. The microneedle array enabled efficient...
Active tether and transportation of cargoes on cytoskeletal highway enabled by molecular motors is key for accurate delivery of vesicles and organelles in the complex intracellular environment. Here, a hybrid system composed of colloidal motors and self‐assembled lipid tubes is designed to mimic the subcellular traffic system in living cells. The colloidal motors, composed of gold‐coated hematite,...
Helicobacter pylori (H. pylori) infection has been the leading cause of gastric cancer development. In recent years, the resistance of H. pylori against antibiotic treatment has been a great challenge for most countries worldwide. Since biofilm formation is one of the reasons for the antibiotic resistance of H. pylori, and phototherapy has emerged as a promisingly alternative antibacterial treatment,...
High‐performance X‐ray detectors have immense potential in medical and security inspections. However, the current X‐ray detectors are limited in flexible, high‐spatial‐resolution large‐scale detection, and integration for imaging. Here, nuclear track‐etched porous polyethylene terephthalate (PET) is developed as the template for preparing uniform, large‐area (≥105 cm2), and flexible metal halide (MH)‐based...
Foreign body reactions (FBR) to implants seriously impair tissue‐implant integration and postoperative adhesion. The macrophage, owing to its phenotypic plasticity, is a major regulator in the formation of the inflammatory microenvironment; NF‐κB signaling also plays a vital role in the process. It is hypothesized that NF‐κB phosphorylation exerts a proinflammatory regulator in FBR to polylactide...
Pathogenic infections seriously threaten public health and have been considered as one of the most critical challenges in clinical therapy. Construction of a safe and efficient photothermal antibacterial platform is a promising strategy for treatment of bacterial infections. Considering that high temperature does harm to the normal tissues and cells, herein, a bacteria‐triggered multifunctional hydrogel...
Nanoparticle‐based tumor immunotherapy has emerged to show great potential for simultaneously regulating the immunosuppressive tumor microenvironment, reducing the unpleasant side effects, and activating tumor immunity. Herein, an excipient‐free glutathione/pH dual‐responsive prodrug nanoplatform is reported for immunotherapy, simply by sequentially liberating 5‐aminolevulinic acid and immunogenically...
In article number 1906432, Dan‐Hong Wang, Xian‐He Bu, and co‐workers present a novel design strategy aiming to form heteropoly blues confined in defected Zr‐metal–organic framework (MOF), which can expose more unsaturated metal sites to promote the catalytic activity by adding thiourea. Moreover, 1‐butyl 3‐methyl imidazolium phosphomolybdate blues are also confined in Zr‐MOF to obtain higher oxidative...
The Keggin‐type polyoxometalates (POMs) are effective catalysts for oxidative desulfurization (ODS) and confining these POMs in metal–organic frameworks (MOFs) is a promising strategy to improve their performances. Herein, postsynthetic modification of POMs confined in MOFs by adding thiourea creates more unsaturated metal sites as defects, promoting ODS catalytic activity. Additional modification...
Perforated ultrathin Pd nanosheets with crystalline/amorphous heterostructures are rationally synthesized to offer a large electrochemically active surface area of 172.6 m2 g−1 and deliver a 5.6 times higher apparent reaction rate in comparison to commercial Pd/C, thus offering a facile confined growth method to generate superior catalysts.
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.
Photocatalytic pathways are proved crucial for the sustainable production of chemicals and fuels required for a pollution‐free planet. Electron–hole recombination is a critical problem that has, so far, limited the efficiency of the most promising photocatalytic materials. Here, the efficacy of the 0D N doped carbon quantum dots (N‐CQDs) is demonstrated in accelerating the charge separation and transfer...
The vesicle is one of the most intriguing platforms for drug delivery, which is believed to improve drug efficacy. In the past few decades, a great deal of materials have been explored to make vesicles, including lipids, block copolymers, dendrons, erythrocyte membranes, and even DNA. Other than shape and size control, most efforts are focused on achieving certain functions, for example, an abundance...
