Reusable thermal cycling clamp [PDF]

, 1985
A reusable metal clamp for retaining a fused quartz ampoule during temperature cycling in the range of 20 deg C to 1000 deg C is described. A compressible graphite foil having a high radial coefficient of thermal expansion is interposed between the fused

The life sulfuric: microbial ecology of sulfur cycling in marine sediments

Environmental Microbiology Reports, 2017
Summary Almost the entire seafloor is covered with sediments that can be more than 10 000 m thick and represent a vast microbial ecosystem that is a major component of Earth's element and energy cycles. Notably, a significant proportion of microbial life

Mesoscale and microscopic structures record compaction and crystal-melt segregation in silicic mushes

Scientific Reports
Gravitationally-driven compaction has been proposed as an important mechanism for crystal-melt segregation in silicic mushes. However, there is no microstructural evidence of crystal deformation consistent with compaction in silicic plutonic rocks.

Microbial control over carbon cycling in soil

Front. Microbio., 2012
A major thrust of terrestrial microbial ecology is focused on understanding when and how the composition of the microbial community affects the functioning of biogeochemical processes at the ecosystem scale (meters-to-kilometers and days-to-years). While
