Passive solar vapor generation represents a promising and environmentally benign method of water purification/desalination. However, conventional steam techniques usually rely on costly cumbersome optical concentration systems have relatively low efficiency due to bulk heating the entire liquid volume. Here, an efficient strategy using extremely low‐cost materials, i.e., carbon black (powder), hydrophilic porous paper, expanded polystyrene foam is reported. Due excellent thermal insulation...
Abstract 100% efficiency is the ultimate goal for all energy harvesting and conversion applications. However, no process reported to reach this ideal limit before. Here, an example with near perfect in of solar vapor generation below room temperature reported. Remarkably, when operational system that surroundings (i.e., under low density illumination), total rate higher than upper can be produced by input because extra taken from warmer environment. Experimental results are provided validate...
Abstract Reliability, shelf time, and uniformity are major challenges for most metallic nanostructures surface‐enhanced Raman spectroscopy (SERS). Due to the randomness of localized field supported by silver gold nanopatterns in conventional structures, quantitative analysis target practical application SERS sensing is a challenge.

Abstract The performance of surface‐enhanced Raman spectroscopy (SERS) is determined by the interaction between highly diluted analytes and boosted localized electromagnetic fields in nanovolumes. Although superhydrophobic surfaces are developed for analyte enrichment, i.e., to concentrate transfer toward a specific position, it still challenging realize reproducible, uniform, sensitive SERS substrates over large scales, representing major barrier practical sensing applications. To overcome...

Ultra-precision machining is widely used in the manufacturing of national defense and sophisticated civil products because its high precision, nearly no surface damage other advantages. The roughness a workpiece key indicator ultraprecision technology, which affected by many factors process machining. However, existing prediction model only considers single error factor between tool workpiece, lacking comprehensive consideration multisource factors. Therefore, based on research factor,...
Aluminum hydride (AlH3) has attracted wide attention due to its high gravimetric and volumetric hydrogen capacity. AlH3 can easily release when heated at relatively low temperature.
