Covalent organic polymers can adsorb three times more refrigerant than the best available alternatives, resulting in more efficient cooling.
Cryocoolers are ultracold refrigeration units used in surgery and drug development, semiconductor fabrication, and spacecraft. The regenerative heat exchanger, or regenerator, is a core component of cryocoolers. At temperatures below 10 kelvins, performance drops precipitously, with maximum regenerator loss of more than 50%. In Applied Physics Letters, researchers used superactivated carbon particles as an alternative regenerator material to increase cooling capability at temperatures as low as 4 kelvins.
A team of Lawrence Livermore National Laboratory researchers has found that the global climatic consequences of a regional nuclear weapons exchange could range from a minimal impact to more significant cooling lasting years.
After a nuclear war, wild-catch marine fisheries will not offset the loss of food grown on land, especially if widespread overfishing continues, according to a Rutgers co-authored study. But effective pre-war fisheries management would greatly boost the oceans’ potential contribution of protein and nutrients during a global food emergency, according to the study in the journal Proceedings of the National Academy of Sciences. The study for the first time explored the effects of nuclear war on wild-catch marine fisheries.
A new study explored the pros and cons of seawater air-conditioning as an alternative cooling solution.
A Buffalo State physics professor is researching ways to make refrigeration and air conditioning environmentally friendly.
Research suggests that wearing water-soaked clothing in hot, humid weather may be an inexpensive and effective way to provide cooling and reduce the risk of heat strain in older adults.
Article title: Keeping older individuals cool in hot and moderately humid conditions: wetted clothing with and without an electric fan Authors: Matthew N. Cramer, Mu Huang, Gilbert Moralez, Craig G. Crandall From the authors: “These findings suggest that wearing a water-soaked T-shirt…
