High-frequency dynamics of liquid and supercritical nitrogen

High-frequency subsurface and bulk dynamics of liquid indium.

We have performed bulk and surface-sensitive inelastic x-ray scattering experiments on liquid indium with 3 meV energy resolution. The experimental data are well reproduced within a generalized hydrodynamic model including structural and microscopic relaxation processes. We find a longitudinal viscosity of 22 mPa s in the near-surface region compared to 7.4 mPa s in the bulk. The origin of the ...

Dynamics of liquid films exposed to high-frequency surface vibration.

We derive a generalized equation that governs the spreading of liquid films under high-frequency (MHz-order) substrate vibration in the form of propagating surface waves and show that this single relationship is universally sufficient to collectively describe the rich and diverse dynamic phenomena recently observed for the transport of oil films under such substrate excitation, in particular, R...

DNA Extraction of Almond without Phenol and Liquid Nitrogen

Genomic DNA extraction with a high quantity and quality is a basic requirement in molecular biology. The DNA obtained was free of any contamination proteins, polysaccharide, polyphenols and colored pigments. These compounds would interfere with the genomic isolation procedures and downstream reactions such as restriction enzyme analysis and gene amplification. The isolated genomic DNA was fo...

Solvent capabilities of liquid and supercritical xenon

A great majority of “interesting” compounds in fluorine and noble gas chemistry are thermodynamically unstable, highly oxidative and thus hard to isolate and characterize materials. Since the ultimate characterization structural determination is very often related to a route to crystalline products, the aforementioned unique properties severely restrict the choice of a solvent for these compoun...
