Microbial Community Diversity Within Sediments from Two Geographically Separated Hadal Trenches

open access: yesFrontiers in Microbiology, 2019
Hadal ocean sediments, found at sites deeper than 6,000 m water depth, are thought to contain microbial communities distinct from those at shallower depths due to high hydrostatic pressures and higher abundances of organic matter.

Formation of Micro- and Nano-Trenches on Epitaxial Graphene

open access: yesApplied Sciences, 2018
Catalytic cutting by metal particles under an atmosphere environment is a promising method for patterning graphene. Here, long straight micro-trenches are produced by the sliding of metal particles (Ag and In) on epitaxial graphene (EG) substrate under ...
