PYCS and CHCS, are mixed with activator, namely NaOH and KOH physically with desired mass ratio in the mortar. Given alkaline corrosion to quartz tube in practical experiment and environmental merit by using less activation agent, mass ratio of 1:1 is concerned. Afterwards, the mixed samples ...
(MoBio, now Qiagen, 26000), which was selected for its ability to isolate high quality RNA from stool54. Each frozen stool was homogenized using a mortar and pestle cooled with liquid nitrogen55, and 150 mg of each sample was loaded into each glass bead tube. Mechanical lysis was ...
A disadvantage of TRCs is that most of their deformation capacity and crack distribution are utilised at low load levels (after mortar cracking and under service loads). This leads to the development of wide cracks and low energy dissipation capacity at the ultimate limit state. Few recent studie...
The biochar and KOH were thoroughly ground in an agate mortar in a 1:2 mass ratio, and then the mixture was heated at 700 ~ 900 °C (5 °C min−1) for 1 h under argon flow. After that, the activated samples were thoroughly washed with 10 wt % HCl and distilled ...
