Zinc also supports healthy growth and development during pregnancy, infancy, childhood, and adolescence and is involved in the sense of taste [ 2, 3, 5 ]. The total amount of zinc in the body is approximately 1.5 g in women and 2.5 g in men [ 2 ]. Most of this zinc is stored in skeletal muscle and bone [ 1-3 ].

An increase of the Zinc content in sludge of almost (from 33% to 46% w/w) was obtained by replacing the commonly used treatment with Lime and FeCl3 with the introduction of NaOH and SPS water. This increase in Zn content made recovery of Zinc cost effective. The residual concentration of Zn and Fe in the wastewater resulting from …
We present an in-depth characterization of the impact of the double zinc diffusion 2D profile on the charge persistence effect in InGaAs/InP Single-Photon Avalanche Diodes (SPADs). Charge persistence might be mitigated by increasing the operating temperature, so as to reduce minority carriers' lifetime, as well as by increasing the …
