In this work, a study of the efficiency carbon dioxide energy cycles different architecture is carried out. The relevance these technical solutions in modern conditions shown. Basic options zero emission thermodynamic using CO 2 as an cycle fluid are presented. It shown that analyzed -cycles with initial temperature 1000 °C will be 54-58%, depending on their configuration. presented can increas...

Abstract The definition of ambitious life cycle-based benchmarks and target values to limit the GHG emissions buildings is seen as one most important steps in pushing construction real estate sector significantly reducing its contribution global warming. Especially are no longer only developed from a bottom-up perspective. There now an interest by governments sustainability assessment system pr...

An infrared-selected, narrow-line QSO has been found to exhibit an extraordinarily broad Hα emission line in polarized light. Both the extreme width (35,000 km s full-width at zero intensity) and 3,000 km s redshift of the line centroid with respect to the systemic velocity suggest emission in a deep gravitational potential. An extremely red polarized continuum and partial scattering of the nar...

The effect of temperature on fluorescence and emission anisotropy spectra of 4-cyano-N,Ndimethylaniline (CDMA) was investigated in viscous (glycerol and paraffin oil) and rigid (polyvinyl alcohol) PVA and polyvinyl chloride) PVC) media. A strong effect of temperature on the intensity of a and b emission bands was observed. It was also found that the emission anisotropy, r, does not vary in the ...

• Self-separable H 2 fuel without forming CO x over 2D SnS/g-C 3 N 4 heterojunction. Selective redox-reactions enabled higher value-added liquid chemicals. Ultra-stable new-record efficiency in producing with low-cost catalyst. Sustainable constructive utilization of elements from alcohols. To reach Paris Agreement’s target 1.5 °C global temperature increase by 2100, low emission strategies are...
