Low-Pressure Plasma-Processed Ruthenium/Nickel Foam Electrocatalysts for Hydrogen Evolution Reaction.

In this paper, low-pressure 95%Ar-5%H, pure Ar, and 95%Ar-5%O plasmas were used for post-treatment of ruthenium (Ru) deposited on nickel foam (NF) (Ru/NF). Ru/NF was then tested as a catalyst for a hydrogen evolution reaction. Significant improvement in electrocatalytic activity with the lowest overpotential and Tafel slope was observed in an alkaline electrolyte (1 M KOH) with 95%Ar-5%O plasma processing on Ru/NF.

Grip force and heart rate responses to manual carrying tasks: effects of material, weight, and base area of the container.

This study recruited 16 industrial workers to examine the effects of material, weight, and base area of container on reduction of grip force (ΔGF) and heart rate for a 100-m manual carrying task. This study examined 2 carrying materials (iron and water), 4 carrying weights (4.4, 8.

BMP-9 as a potent brown adipogenic inducer with anti-obesity capacity.

BMP-9, whose expression is highest in liver cells, has been demonstrated to regulate expression of enzymes involved in glucose homeostasis. However, the underlying mechanism of this effect has yet to be elucidated. We observed that MB109, a recombinant BMP-9 derivative, enhanced brown adipogenesis of human adipose tissue derived stem cells.
