This study aims at analyzing the phenomenon of siphon draining occurring in drainback solar thermal systems. Although several experimental studies have been previously carried out, there is a lack of theoretical work in the literature. Since describi

We report on an intense red emission spectrum which is obtained when a high-concentration flow of chemically produced metastable oxygen O2(1Δg) passes over various heated metals and on a search of a chemical-laser effect. The visible and IR emission
