Phase change materials (PCMs) have attracted much attention in the field of solar thermal utilization recently, due to their outstanding thermal energy storage performance. However, PCMs usually release their stored latent heat spontaneously as the temperature below the phase transition temperature, ren-...
"They can work through severe conditions like strong ultraviolet light and low temperature," said Wang Yang, head of the wind farm. From the end of 2021 to January 2024, the cumulative grid-connected electricity generated by the wind farm exceeded 214 million kWh. This amount of electricity ...
It is known that temperature estimates of macroscopic systems in equilibrium are most precise when their energy fluctuations are large. However, for nanoscale systems deviations from standard thermodynamics arise due to their interactions with the environment. Here we include such interactions and, using ...
During selenization of CZTSSe film at high temperature, the reaction between CZTSSe and Mo is one of the main reasons that result in unfavorable absorber and interface qual-ity, which leads to large open circuit voltage deficit (VOC-def) and low fill factor (FF). Herein, a WO3 inter-...
OTEC utilizes large temperature differences between the sea surface and deep ocean to generate electricity, providing a renewable solution to fueling our future, he explained. In this study, recently published in the journal Nature Communications, scientists evaluated the change of global OTEC resources...
to remove ice templates; (ii) the limited scalability of ice-templated materials due to the lowest temperature that restricts ice crystal growth; (iii) the lengthy fabrication periods due to the slow velocity of the ice front; and (iv) the difficulty in controlling ice growth leading to ...
All pathways suggest an inevitable decline in per capita net energy at some point during the transition. However, this finding does not mean that energy scarcity is an unavoidable feature of any low-carbon energy transition. The projected net energy decline is not due to constrained possibilities ...

and the temperature have a positive effect on carbon dioxide emission, while energy usage has an adverse impact on carbon dioxide emission in developing countries, as in the Pakistan country, making local government to take the requisite measures to curb carbon dioxide emission in order to improve...
High-temperature DH systems continue to incur significant heat losses and expensive installation fees. Due to the high water retention period in the network, heat losses can reach approximately 30% of the supplied energy, particularly in the summer when the majority of DH systems are operating to...
