Comprehensive biomedical applications of low temperature plasmas
The main component of plasma medicine is the use of low-temperature plasma (LTP) as a powerful tool for
biomedical applications. LTP generates high reactivity at low temperatures and can be activated with noble gases
with ...
Influence of spray-drying operating conditions on Rhamnus purshiana (Cáscara sagrada) extract powder physical properties
(Elsevier Science Sa, 2011-03)
The aim of this work was to study Rhamnus purshiana (Cáscara sagrada) extract spray-drying in order to obtain powders with good rheological properties for direct compression (DC) and stability attributes. The experiments ...
Scheme of thermal compression of hydrogen (TCH) using MmNi4.25Al0.75 recovered with ethyl alcohol and handled under non protective atmospheres
(Elsevier, 2014-03)
A MmNi4.25Al0.75 intermetallic was obtained by low energy mechanical alloying and low temperature heating at 600 °C for 24 h under Ar. The intermetallic was recovered from milling chamber using ethyl alcohol, dried, stored ...
