Despite the considerable advances of deposition technologies, it remains a significant challenge to form conformal deposition on surface of nanoporous carbons. Here, we introduce a new ambient hydrolysis deposition method that employs and controls pre-adsorbed water vapor on nanoporous carbons to define the deposition of TiO₂. We converted the deposited...

We, for the first time, demonstrate that orthorhombic V₂O₅ can exhibit superior electrochemical performance in sodium ion batteries when uniformly coated inside nanoporous carbon. The encapsulated V₂O₅ shows a specific capacity as high as 276 mAh/g, while the whole nanocomposite exhibits a capacity of 170 mAh/g. The V₂O₅/C composite was...

Na-ion batteries are emerging as one of the most promising energy storage technologies, particularly for grid-level applications. Among anode candidate materials, hard carbon is very attractive due to its high capacity and low cost. However, hard carbon anodes often suffer a low first-cycle Coulombic efficiency and fast capacity fading. In...

A low-voltage plateau at ∼0.3 V is discovered during the deep sodiation of Na₃V₂(PO₄)₃ by combined computational and experimental studies. This new low-voltage plateau doubles the sodiation capacity of Na₃V₂(PO₄)₃, thus turning it into a promising anode for Na-ion batteries.

In eukaryotes, ARGONAUTE proteins (AGOs) associate with microRNAs (miRNAs), short
interfering RNAs (siRNAs), and other classes of small RNAs to regulate target RNA or target
loci. Viral infection in plants induces a potent and highly specific antiviral RNA silencing
response characterized by the formation of virus-derived siRNAs. Arabidopsis thaliana has...
Continental precipitation not routed to the oceans as runoff returns to the atmosphere
as evapotranspiration. Partitioning this evapotranspiration flux into interception, transpiration,
soil evaporation, and surface water evaporation is difficult using traditional hydrological
methods yet critical for understanding the water cycle and linked ecological processes. We
