Analytical thermal modelling of double slope solar still by using inner glass cover temperature

Shukla, S.K.; Rai, A.K. (2008)

In this paper, expressions for water and glass temperatures, hourly yield and instantaneous efficiency for double slope solar distillation systems have been derived analytically. The analysis is based on the basic energy ...
Effect of host on the radiative (upconversion emission) as well as non-radiative relaxation (laser induced optical heating) in Tm3+/Yb3+ co-doped phosphors

Dwivedi, A.; Kumar, D.; Rai, S.B.; Rai, A.K. (Elsevier B.V., 2020-10)

Tm3+/Yb3+ co-doped YVO4 (YVO:Tm, Yb); GdVO4 (GVO:Tm, Yb); Y2O3 (YO:Tm, Yb); Gd2O3 (GdO:Tm, Yb) and CaAl2O4 (CAO:Tm, Yb) phosphor samples have been synthesized using high temperature Solid State Reaction method. X-ray ...
