Changes in Ginsenoside Compositions by High Temperature Processing under Various Soaking Conditions

autoignition of gaseous fuels in various oxidizer volumetric compositions in high temperature

the paper presents results of experimental studies on the methane and propane ignition process in various volumetric compositions of oxidizers heated to temperatures higher than ignition point of analyzed fuels (htac conditions–high temperature air combustion conditions). the increment of temperature dt and the ignition delay time tig are parameters characterizing the process of ignition under ...

Changes in ginsenoside compositions and antioxidant activities of hydroponic-cultured ginseng roots and leaves with heating temperature

BACKGROUND This study evaluated changes in ginsenoside compositions and antioxidant activities in hydroponic-cultured ginseng roots (HGR) and leaves (HGL) with heating temperature. METHODS Heat treatment was performed at temperatures of 90°C, 110°C, 130°C, and 150°C for 2 hours. RESULTS The ginsenoside content varied significantly with heating temperature. The levels of ginsenosides Rg1 and...

Thermomechanics of nanocrystalline nickel under high pressure-temperature conditions.

We present a comparative study of thermomechanical properties of nano-polycrystalline nickel (nano-Ni) and micrometer-polycrystalline nickel (micron-Ni) by in situ high pressure-temperature (P-T) diffraction experiments. The yield strength of 2.35 GPa for the nano-Ni measured under high-pressure triaxial compression is more than three times that of the micron-Ni value. Contrary to tensile exper...
