UW Smogmobile Offers Cleaner, Safer Alternative To Gas Or Electric Cars
...ains, a plant would simply run air through a large refrigeration system and collect the liquid nitrogen as it condenses. In the process, pollutants such as carbon dioxide also are removed from the air and could be disposed of in a benign manner. Hertzberg pursued the smogmobile project in part to pull the plug on ...Report Notes Difficulties In Eliminating E. Coli O157:H7 From Food Supply
...urvival time in these foods is greatly extended at refrigeration temperatures(32 F-40 F) as opposed to room temperature. Recent studies have also indicatedthat acid tolerance may increase the pathogen's resistance to other stressessuch as heat, radiation, and antimicrobials.

...t would reduce or eliminate the need to send power refrigeration equipment into the field, or could be used to fend off common diseases that soldiers might be exposed to. The report suggests that such anti-infection agents would be made from edible proteins or peptides instead of pharmaceuticals.

...animal tissues. The use of CFCs -- widely used in refrigeration systems, aerosols, styrofoam and other products in the 1960s and 70s -- has been replaced by hydrochlorofluorocarbon (HCFCs) and hydrofluorocarbon (HFCs) gases. Unlike CFCs, these gases break down in the atmosphere and return to Earth in the form of ...The science of the scoop: Wheat proteins for ice cream?
...roteins to the particles' surfaces. In the ensuing refrigeration step, the fat must be crystallized right away, to achieve the desired liquid and crystal proportions. The mix is then frozen, changing much of the liquid water into ice and incorporating air into the mixture. The smaller the air bubbles, fat particle...American Physical Society March Meeting 2003
