Li–S batteries are regarded as promising devices for energy storage systems owing to high energy density, low cost, and environmental friendliness. However, challenges of polysulfides shuttling in sulfur cathode and dendrite growth of lithium anode severely hinder the practical application. Developing advanced skeletons simultaneously regulating the cathode and anode is significant and challenging...
2D transition metal disulfides (TMDs) are promising and cost‐effective alternatives to noble‐metal‐based catalysts for hydrogen production. Activation of the inert basal plane of TMDs is crucial to improving the catalytic efficiency. Herein, introduction of in‐plane sulfur vacancies (Sv) and 3d transition metal dopants in concert activates the basal planes of MoS2 (M‐Sv‐MoS2) to achieve high activities...
Cost‐effective electrocatalysts for the hydrogen evolution reaction (HER) spanning a wide pH range are highly desirable but still challenging for hydrogen production via electrochemical water splitting. Herein, Mo5N6‐MoS2 heterojunction nanosheets prepared on hollow carbon nanoribbons (Mo5N6‐MoS2/HCNRs) are designed as Mott–Schottky electrocatalysts for efficient pH‐universal HER. The in‐plane Mo5...
Photocatalysis technology using solar energy for hydrogen (H2) production still faces great challenges to design and synthesize highly efficient photocatalysts, which should realize the precise regulation of reactive sites, rapid migration of photoinduced carriers and strong visible light harvest. Here, a facile hierarchical Z‐scheme system with ZnIn2S4/BiVO4 heterojunction is proposed, which can...
The feasibility of transition metal carbides (TMCs) as promising high‐rate electrodes is still hindered by low specific capacity and sluggish charge transfer kinetics. Improving charge transport kinetics motivates research toward directions that would rely on heterostructures. In particular, heterocomposing with carbon‐rich TMCs is highly promising for enhancing Li storage. However, due to limited...
The mechanism of cells passing through microconstrictions, such as capillaries and endothelial junctions, influences metastasis of circulating tumor cells (CTCs) in vivo, as well as size‐based enrichment of CTCs in vitro. However, very few studies observe such translocation of microconstrictions in real time, and thus the inherent biophysical mechanism is poorly understood. In this study, a multiplexed...
Bone metastasis occurs at ≈70% frequency in metastatic breast cancer. The mechanisms used by tumors to hijack the skeleton, promote bone metastases, and confer therapeutic resistance are poorly understood. This has led to the development of various bone models to investigate the interactions between cancer cells and host bone marrow cells and related physiological changes. However, it is challenging...
Rapid and simultaneous detection of multiple potential pathogens by portable devices can facilitate early diagnosis of infectious diseases, and allow for rapid and effective implementation of disease prevention and treatment measures. The development of a ZnO nanorod integrated microdevice as a multiplex immunofluorescence platform for highly sensitive and selective detection of avian influenza virus...
In article number 1700425, Si‐Yang Zheng and co‐workers, develop a smart ZnO nanorods integrated microdevice for highly sensitive and multiplex avian influenza virus detection. By dissolving ZnO nanorods in a low acid environment, the captured viruses could be released for the subsequent analysis. This technology can be expanded to detect other pathogens and disease biomarkers in clinical trials....
In article number 1603135, S.‐Y. Zheng and co‐workers develop a point of care device integrated with porous silicon nanowire forests for influenza virus capturing based on their sizes only. By dissolving nanowire forests in physiological aqueous environments, subsequently captured viruses could be released without damage for culturing, characterization, and other analysis. The device shows potential...
Viral diseases are perpetual threats to human and animal health. Detection and characterization of viral pathogens require accurate, sensitive, and rapid diagnostic assays. For field and clinical samples, the sample preparation procedures limit the ultimate performance and utility of the overall virus diagnostic protocols. This study presents the development of a microfluidic device embedded with...
