Nucleation rate measurements of water in the presence of nitrogen as a carrier gas are reported at total pressures near 10, 25, and 40 bar, and temperatures of 230 and 250 K. The results were obtained using our pulse-expansion wave tube, particularly suited for high pressure nucleation research. Enhanced fugacity of water vapor in the mixture, due to the presence of nitrogen, was quantitatively...

We discuss the recently devised one-loop gap equation for the magnetic mass of hot QCD. An alternative, and one would hope equivalent, gap equation is presented, which however shows no mass generation at the one-loop level.

Physical and chemical barriers separate individual terrestrial hot springs and their affiliated communities of thermophilic bacteria. However, 16S rRNA gene sequence comparisons suggest that seemingly identical or closely related bacterial species are found in multiple hot springs that are separated by distances that range from a few meters to thousands of kilometers. To investigate whether thi...

in this investigation, cuins2 ternary compound was synthesized by injection of thiourea solution into a hot copper-indium solution. the cucl, incl3 along with (sc (nh2)2) were used as a precursor dissolved in high boiling point solvent such as oleylamine (ch(ch2)17nh2) and oleic acid (ch(ch2)16cooh) as a coordination solvent and capping agent, respectively. the size, distribution and shape were...

The aquifer thermal energy storage system (ATES) owing to growing demands for sustainable energy has become a popular technology in last few decades for long term storing of excess thermal energy. The efficiency of such a system depends entirely on the capacity of the aquifer to retain heat and hence modeling the heat transfer and transient temperature distribution in the aquifer due to hot wat...
