Radiative cooling is an emerging sustainable technology that does not require electricity to function. However, realize sub-ambient cooling, the effects of undesired incident solar energy must be minimized. Considering ideal blackbody radiator at 300 K, maximum power density ?160 W/m 2 . Here, we report architecture capable overcoming this challenge by using two spectrally selective mirrors sim...
freeze concentration is a process of concentrating liquid products by freezing the water content and subsequently removing the so-formed ice crystals from the food system. in dairy processing, this technology offers the advantage of minimizing the heat abuse of sensitive milk components, such as proteins and flavors. it thus provides an opportunity for producing dairy ingredients with enhanced ...
The Bactec 9240 and the BacT/Alert blood culture systems were compared as a means for detection of bacterial contaminants in whole blood, concentrated red cells, and plasma preparations prepared from umbilical cord blood (UCB) samples. Ninety-two UCB units seeded with low levels of various bacteria were evaluated. In more than 50% of cases, growth was not detected in plasma using either system ...
