The research on systems with coexistence of superconductivity and nontrivial band topology has attracted widespread attention. However, the limited availability of material platforms severely hinders the research progress. Here, it reports the first experimental synthesis and measurement of high‐quality single crystal van der Waals transition‐metal dichalcogenide InNbS2, revealing it as a topological...
The development of efficient and affordable electrode materials is crucial for clean energy storage systems, which are considered a promising strategy for addressing energy crises and environmental issues. Metal phosphorous chalcogenides (MPX3) are a fascinating class of two‐dimensional materials with a tunable layered structure and high ion conductivity, making them particularly attractive for energy...
Given the ability to convert various ambient unused mechanical energies into useful electricity, triboelectric nanogenerators (TENGs) are gaining interest since their inception. Recently, ionogel‐based TENGs (I‐TENGs) have attracted increasing attention because of their excellent thermal stability and adjustable ionic conductivity. However, previous studies on ionogels mainly pursued the device performance...
Replacing liquid electrolytes with solid polymer electrolytes (SPEs) is considered as a vital approach to developing sulfur (S)‐based cathodes. However, the polysulfides shuttle and the growth of lithium (Li) dendrites are still the major challenges in polyethylene oxide (PEO)‐based electrolyte. Here, an all‐solid‐state Li metal battery with flexible PEO‐Li10Si0.3PS6.7Cl1.8 (LSPSCl)‐C‐lithium bis(trifluoromethanesulfonyl)imide...
Abnormal elevated levels of cytokines such as interferon (IFN), interleukin (IL), and tumor necrosis factor (TNF), are considered as one of the prognosis biomarkers for indicating the progression to severe or critical COVID‐19. Hence, it is of great significance to develop devices for monitoring their levels in COVID‐19 patients, and thus enabling detecting COVID‐19 patients that are worsening and...
Direct tracing of small extracellular vesicle (sEV) cargoes holds unprecedented importance for elucidating the mechanisms involved in intercellular communication. However, high‐fidelity determination of sEVs’ molecular cargoes in situ has yet to be achieved due to the difficulty in transporting molecular probes into intact sEVs. Herein, a fLuorescent Intracellular‐Guided Hairpin‐Tetrahedron (fLIGHT)...
The energy transfer from plasmonic nanostructures to semiconductors has been extensively studied to enhance light‐harvesting and tailor light–matter interactions. In this study, the efficient energy transfer from an Au metasurface to monolayered MoS2 within a near‐field coupling regime is reported. The metasurface is designed and fabricated to demonstrate strong photoluminescence (PL) and cathodoluminescence...
In article number 2002800, Guixue Wang, Yang Luo, and co‐workers introduce a DNA origami nanoprobe “fLIGHT” for high‐fidelity visualization of small extracellular vesicle microRNAs without RNA extraction. This innovative platform can aid in easy development of a universal molecular detection strategy that could facilitate extracellular vesicle‐derived fundamental biological studies.
Real‐time quantitative monitoring of miRNAs plays an essential role in diagnosis and therapeutics. Herein, a DSN‐coupled graphene nanoarray/gold nanoparticles (GNAs/AuNPs) carbon paper (CP) electrode for the dynamic, sensitive, and real‐time analysis of miRNAs is reported. GNAs are vertically grown on the conductive CP by radio frequency plasma enhanced chemical vapor deposition, and AuNPs are electrodeposited...
Plasma functionalization can increase the efficiency of MoSe2 in the hydrogen evolution reaction (HER) by providing multiple species but the interactions between the plasma and catalyst are not well understood. In this work, the effects of the ion energy and plasma density on the catalytic properties of MoSe2 nanosheets are studied. The through‐holes resulting from plasma etching and multi‐vacancies...
Recently, researchers have made significant advancement in employing transition metal compound hybrids as anode material for lithium‐ion batteries and developing simple preparation of these hybrids. To this end, this study reports a facile and scalable method for fabricating a vanadium oxide–nitride composite encapsulated in amorphous carbon matrix by simply mixing ammonium metavanadate and melamine...
