Solar vapor generation is emerging as one of the most important sustainable techniques for harvesting clean water using abundant and green solar energy. The rational design evaporators to realize high evaporation performances has become a great challenge. Here, porous evaporator with integrative optimization photothermal convention, transport thermal management developed attractive Pickering em...

the examination of available vapor pressure data in the case of the methane, ethane, propane and butane halogenated refrigerants, allowed recommendations of standard equations for this property. in this study, three new models include a general correlation; a substance-dependent correlation and an artificial neural network (ann) approach have been developed to estimate the saturated vapor press...

nanoporous graphene which is used as nanosorbent was synthesized by chemical vapor deposition method via porous zinc oxide nanocatalyst. the reaction was carried out using methane as the carbon source and hydrogen as the carrier gas in a ratio of 4:1 at the temperature ranging 900-1050°c for 2-50 min. the product was characterized by scanning electron microscopy, transmission electron microscop...

Estimates are made of the effect of changes in tropospheric water vapor on the climate sensitivity to doubled carbon dioxide (CO2), using a coarse resolution atmospheric general circulation model coupled to a slab mixed layer ocean. The sensitivity of the model to doubled CO2 is found as the difference between the equilibrium responses for control and doubled CO2 cases. Clouds are specified to ...

Phase change materials employed as thermal energy storage can aid in maximizing the use of stored solar energy. The current research examined impact three kinds phase (PCMs) on dynamic performance a organic Rankine cycle (ORC) system based direct vapor production. A number evacuated flat plate collectors, condenser, an expander, and fluid pump make up this system. thermodynamic model generation...
