Packaging was recently identified as an essential element in addressing the key challenge of sustainable food supply and is gaining interest among researchers. It a central quality preservation due to its role heat mass exchange with external atmosphere, contributing during storage extending shelf life. This work proposes three new packaging configurations same size but different geometry venti...

Using a simple and cost-effective water jet process, silicon etch depth limitations are overcome to realize 6 mm deep atomic vapor cell. While the minimum feature size was limited 1.5 width in these first generation cells, we successfully demonstrate two-chamber geometry by including [Formula: see text] meandering channel between alkali pill chamber main interrogation chamber. We evaluate impac...

High-pressure fluctuation and flow ripple may cause unexpected vibration noise when the piston pump works under severe conditions, eventually lead to hydraulic transmission failure. The geometry of valve plate has a great influence on pressure chamber. In order optimize structure plate, mathematical model considering slot leakage lubricating interfaces was established in this paper. used invest...

To obtain precise and reliable laboratory clearance rate (filtration rate) measurements with the 'flow-through chamber method' (FTC) the design must ensure that only inflow water reaches the bivalve's inhalant aperture and that exit flow is fully mixed. As earlier recommended these prerequisites can be checked by a plot of clearance rate (CR) versus increasing through-flow (Fl) to reach a plate...

A drying multi-component liquid droplet in a confined geometry leaves uniform dried pattern. The evaporated vapors are stagnated inside the closed chamber, which induce Marangoni effects that contribute to suppress coffee-ring
