Abstract Pharmacological concentrations of zinc (Zn, 2000-3000 ppm) are commonly fed to nursery pigs. However, diet manufacturing errors can result in supra-pharmacological concentrations of Zn (>4000 ppm) being fed. Clinical and phenotypic data reflective of Zn associated morbidity in modern genotype pigs are poorly defined. Therefore, the study objective was to characterize the effect of dietary Zn overload on nursery pig performance, body mineral concentrations and pathologic changes. Fifty-five 21 d old weaned pigs (4.50 ± 0.2 kg BW) were randomly assigned to one of five Zn diet treatme

The purpose of this work is the modeling and simulation of the material behavior of aluminum alloys during extrusion processes. In particular, attention is focused here on aluminum alloys of the 6000 series (Al-Mg-Si) and 7000 series (Al-Zn-Mg). The material behavior of these alloys during extrusion is governed mainly by dynamic recovery and static recrystallization during cooling. The current material model is based on the role of energy stored in the material during deformation, as it acts as the driving force for microstructural development.

The main findings are that optimum sensitivity is obtained at 0.3–142.5 ng/mL and 0.065–60.0 ng/mL for copper and cadmium, respectively, that the complexes responsible for adsorption on the electrode are CuLu and CdLu, and that the sensitivity of the method is much improved in the absence of dissolved oxygen.

AbstractThe limited lifespan of aqueous Zn‐ion batteries (ZIBs) is primarily attributed to the irreversible issues associated with the Zn anode, including dendrite growth, hydrogen evolution, and side reactions. Herein, a 3D Zn anode exposing Zn(002) crystal planes (3D‐Zn(002) anode) is first constructed by an electrostripping method in KNO3 solution. Experiments and theoretical calculations indicate that the priority adsorption of KNO3 on Zn(100) and Zn(101) planes decreases the dissolution energy of Zn atoms, thereby exposing more Zn(002) planes.
