ZnS–Zn nanocables and ZnS nanotubes

Chemical Communications, 2003
ZnS-Zn nanocables and ZnS nanotubes have been synthesized by a thermochemical process in a simple and safe way. The as-prepared nanocables consist of a single crystal Zn core with a diameter of 20 nm and a polycrystalline ZnS sheath with a thickness of 8 nm. The evaporation of the Zn core leads to the formation of ZnS nanotubes.

Critical assessment and optimization of phase diagrams and thermodynamic properties of RE–Zn systems – Part II – Y–Zn, Eu–Zn, Gd–Zn, Tb–Zn, Dy–Zn, Ho–Zn, Er–Zn, Tm–Zn, Yb–Zn and Lu–Zn

Journal of Alloys and Compounds, 2015
Abstract All available phase diagram and thermodynamic data for the Y–Zn, Eu–Zn, Gd–Zn, Tb–Zn, Dy–Zn, Ho–Zn, Er–Zn, Tm–Zn, Yb–Zn and Lu–Zn systems have been collected and critically assessed. Optimized model parameters for the thermodynamic properties of all phases have been obtained.

Thermodynamic assessment of the Ca–Zn, Sr–Zn, Y–Zn and Ce–Zn systems

Calphad, 2008
Abstract Published experimental thermodynamic and phase diagram data for the Ca–Zn, Sr–Zn, Y–Zn and Ce–Zn systems have been critically evaluated to provide assessed thermodynamic parameters for the different phases of the systems. The parameters allow all thermodynamic properties and phase boundaries for each system to be calculated within reasonable

Decamethyldizincocene, a Stable Compound of Zn(I) with a Zn-Zn Bond

Science, 2004
Unlike mercury, which has an extensive +1 oxidation state chemistry, zinc usually adopts the +2 oxidation state. Decamethyldizincocene, Zn 2 (η 5 -C 5 Me 5 ) 2 , an organometallic compound of Zn(I) formally derived from ...

Interfacial tensions in Zn, Zn-Sn and Zn-Sn-Pb systems

Journal of the Less Common Metals, 1977
Abstract Intergranular and solid-liquid interfacial tensions have been determined for Zn-Sn and Zn-Sn-Pb systems. The temperature coefficient of the intergranular tension of solid zinc is negative. Solid-liquid interfacial tension for the Zn-Sn system increases as the tin content increases; the σsl values fit an equation derived from statistical ...

Comparison the Zn-Threonine, Zn-Methionine, and Zn Oxide on Performance, Egg Quality, Zn Bioavailability, and Zn Content in Egg and Excreta of Laying Hens

Biological Trace Element Research, 2020
The experiment was conducted to investigate the effect of supplementary zinc-threonine (Zn-Thr), zinc-methionine (Zn-Met), and zinc oxide (ZnO) on the laying performance, egg quality, Zn content in egg and excreta. One hundred and sixty hens (Hy-Line W36) were randomly divided into 10 treatments with 4 replications of 4 hens each.

The Zn(II)/Zn exchange reaction

Journal of Electroanalytical Chemistry, 1970
Summary The results of an investigation of the kinetics of the Zn(II)/Zn exchange in aqueous electrolytes are reported. Galvanostatic, potentiostatic and faradiac impedance experiments are described. Significant changes in electrode activity occur during the initial 2 h of electrode/electrolyte contact.

Magnetostriction of Ni-Zn and Co-Zn ferrites

physica status solidi (a), 1985
The magnetostriction of polycrystalline mixed nickel-zinc and cobalt-zinc ferrites of different compositions are studied as a function of composition, magnetic field, and temperature, using the strain gauge method. At room temperature it is observed that the values of saturation magnetostriction in both the ferrite systems decrease with the increase of
