Zinc transporters and the cellular trafficking of zinc
Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2006 Zinc is an essential nutrient for all organisms because this metal serves as a catalytic or structural cofactor for many different proteins. Zinc-dependent proteins are found in the cytoplasm and within many organelles of the eukaryotic cell including the nucleus, the endoplasmic reticulum, Golgi, secretory vesicles, and mitochondria.

Dislocation‐Mediated Thermoelectric Performance and Mechanical Behavior
Advanced Engineering Materials, EarlyView.Dislocations can scatter phonons to reduce thermal conductivity, thereby enhance thermoelectric performance. However, dislocations also impact mechanical properties, leading to increased brittleness and altered plasticity. It is essential to clarify the complex relationship between dislocations, thermal transport, and mechanical stability to achieve a ...

Toxicological inhalation studies in rats to substantiate grouping of zinc oxide nanoforms
Particle and Fibre ToxicologyBackground Significant variations exist in the forms of ZnO, making it impossible to test all forms in in vivo inhalation studies. Hence, grouping and read-across is a common approach under REACH to evaluate the toxicological profile of familiar ...

Advanced Engineering Materials, EarlyView.Rotary friction welding of steel E355 and the aluminum alloy EN AW‐6082 can lead to the formation of brittle intermetallic phases. The primary process parameters are varied in order to determine their influence on this intermetallic phase formation and the resulting mechanical properties.

Advanced Engineering Materials, EarlyView.Herein, the electroplating of titanium from an organic solvent, ethaline, is shown. Polymer additives are shown to smooth the roughness of the film, and small molecule additives are shown to produce a near‐mirror finish to the deposited metal. Titanium electroreduction is desired for a variety of medical, electronic, and bonding applications but has ...

Surface Modification of Sol–Gel Synthesized Ba0.85Ca0.15Zr0.1Ti0.9O3 using Stearic Acid Additives
Advanced Engineering Materials, EarlyView.This study explores a novel approach to enhance the piezoelectric performance of lead‐free BCZT ceramics synthesized via the sol–gel method. By coating the BCZT powder with only a 0.69 nm stearic acid layer, the electromechanical response is significantly boosted up to 359 pC N−1, revealing promising implications for high‐performance sensor and ...
