In this paper, the SCO2 Brayton regenerative and recompression cycles are studied optimized for a next-generation solar power tower under maximum cycle temperature of over 700 °C. First, steady-state thermodynamic model is developed validated, impacts different operating parameters on three critical performance indexes, including thermal efficiency, specific work, heat storage difference, analy...

Waste heat recovery (WHR) can represent a solution to improve the efficiency of ships’ propulsion, helping exceed stringent greenhouse gas emission limits. This is particularly suitable in case propulsion based on turbines due their medium-high temperature level exhaust gases. study analyzes performance hybrid energy grid, which recovered by gases an aeroderivative turbine, GE LM2500+, when bot...

Thermodynamic analysis of a novel combined system which is combination of methane fired gas turbine cogeneration system (CGAM) with a supercritical CO2 recompression Brayton cycle (SCO2) and an Organic Rankine Cycle (ORC) is reported. Also, a comprehensive parametric study is performed to investigate the effects on the performance of the proposed system of some important parameters. Finally, a ...

Mitochondrial disorders are highly heterogeneous conditions characterized by defects of the mitochondrial respiratory chain. Pharmacological activation of mitochondrial biogenesis has been proposed as an effective means to correct the biochemical defects and ameliorate the clinical phenotype in these severely disabling, often fatal, disorders. Pathways related to mitochondrial biogenesis are ta...

Injection of carbon dioxide (CO2) into coal seam gas reservoirs has been considered one the most popular approaches to enhance methane (CH4) production. However, many geological and engineering factors influence efficiency CH4 displacement by CO2. These include depth-induced changes in pressure temperature, accompanied compounds, moisture content, salinity underground water. Thereby, mechanisms...

The syntheses, structures, and magnetic properties of a series of tetranuclear cyanide-bridged compounds are reported. This family of molecular squares, [{M(II)Cl2}2{Co(II)(triphos)(CN)2}2] (M = Mn ([CoMn]), Fe ([CoFe]), Co ([CoCo]), Ni ([CoNi]), and Zn ([CoZn]), triphos = 1,1,1-tris(diphenylphosphinomethyl)ethane), has been synthesized by the reaction of Co(II)(triphos)(CN)2 and MCl2 (M = Mn, ...
