Two isostructural 1D compounds {[M3(hpdc)2(H2O)6] 2H2O}n (M = Mn, Co; H3hpde = 2-hydroxypyrimidine-4,6-dicarboxylic acid) were synthesized by the in situ hydrothermal reactions of 2-chloropyrimidine-4,6-dicarboxylic acid with MCl2 (M = Mn, Co) and NaOH; the MnII compound shows spin-canted antiferromagnetism, whereas the CoII compound exhibits the coexistence of spin-canting and a two-step field...

sCO2 power cycle is the most investigated and promising technology for replacing conventional steam in CSP plants. Nevertheless, efficiency of strongly penalized by high ambient temperatures which are typical favourable locations. This paper focuses on a new working fluid cycles consists CO2 blended with C6F6. The addition C6F6 increases critical temperature allowing condensing up to 45 °C. cal...

In this paper, we introduce a class of one-dimensional non-autonomous dynamical systems that allows an explicit study of its orbits as well as of the solutions of the associated variational equation. Furthermore, the solution operators also have explicit representations. In a special case, the model function can be transformed into the non-autonomous Beverton-Holt equation. We use this function...
