The development of laser-assisted atom-probe tomography (APT) analysis and new sample preparation approaches have led to significant advances in the characterization of semiconductor materials and device structures by APT. The high chemical sensitivity and three-dimensional spatial resolution of APT makes it uniquely capable of addressing challenges resulting from the continued shrinking of sem...

Elucidating how changing of the dimensionality affects property matter is key challenge problem nanoscience. In particular, it has recently been reported that 2D liquids have fundamentally different dynamic properties to 3D liquids. Herein, ultimate physical limit addressed, when liquid confined a single-atom layer. The case realized with Tl–Pb alloy layer grown on Si(111) substrate terminated ...

Abstract The CaSi nanowires were synthesized on Si substrate by reactive deposition technique. A great amount of Ca vapor reacted with surface cleaned substrate, and was grown the as-synthesized film. diameter could achieve a minimum value about 25 nm. nanowire self-orient along <001> direction. We can control length experimental parameter settings, such as quantity source, duration time ...

The accurate mapping of urban impervious surfaces from remote sensing images is crucial for understanding land-cover change and addressing impervious-surface-change-related environment issues. To date, the authors most studies have built indices to map based on shortwave infrared (SWIR) or thermal (TIR) bands middle–low-spatial-resolution images. However, this limits use high-spatial-resolution...

Just before the discovery of penicillin by Fleming, reports in the literature appeared that described potent antimicrobial substances produced by lactic acid bacteria. It was found that these substances were specifically active against a wide range of other gram-positive bacteria. These characteristics meant that these compounds were attractive candidates for application in either food preserva...
