We study the dependence of the heat transfer between two semi-infinite solids on the dielectric properties of the bodies. We show that the heat transfer at short separation between the solids may increase by many order of magnitude when the surfaces are covered by adsor-bates, or can support low-frequency surface plasmons. In this case the heat transfer is determined by resonant photon tunnelin...

Abstract Semi-moist pet treats contain moisture content ranging from 20-30% making them ideal for mold growth and mycotoxin production. To control spoilage, synthetic inhibitors, such as potassium sorbate, have been used. Unfortunately, consumers would prefer “natural” preservatives. Whey protein fermentate (WPF) is an efficient antifungal, albeit in large doses. Therefore, the objective of thi...

Activated carbon was prepared from agricultural waste “almond (Prunus amygdalus) nut shells” by chemical activation with phosphoric acid as an activating agent at 450 C for 24 hr soaking time. The physical and chemical properties were analyzed. The adsorption of chromium VI from aqueous solution on almond nut shell activated carbon (ASAC) was investigated. The adsorption process parameters pH, ...
