Nitrogen Solubility in Liquid Silicon

Temperature Dependence of the Solubility of Nitrogen in Liquid Silicon Equilibrated with Silicon Nitride

The solubility of nitrogen in liquid silicon equilibrated with silicon nitride and its dependence on the composition of the atmosphere has been studied in the temperature region 1428–1542 C. High purity silicon was melted in silicon nitride crucibles under Ar and N2 atmospheres. The equilibrium was observed to be established within minutes, after which no evolution of the nitrogen content with ...

Short Communication: DNA Extraction Using Liquid Nitrogen in Staphylococcus aureus

Illuminating liquid polymorphism in silicon.

P hase transitions are phenomena of enduring fascination for scientists studying condensed matter (e.g., the ubiquitous solids and liquids). Much of our ability to rationalize phenomena in the natural world and to design or make new materials depends on our ability to characterize the properties of different phases that substances can exist in and predict conditions under which transitions occu...

Prebreakdown events in liquid nitrogen

2014 It was shown previously that a small volume of liquid nitrogen in front of a sharp metal tip can withstand an extremely high field without any sign of breakdown or charge injection. Subsequently, the influence of the tip radius on the critical field has been investigated and is described here. Also, by monitoring the injection, it has been possible to analyse the influence of the injected ...
