Deep Eutectic Solvents as à-la-Carte Medium for Transition-Metal-Catalyzed Organic Processes

open access: yesMolecules, 2022
Our society is facing a tremendous challenge to become more sustainable in every sphere of life. Regarding the chemical industry, one of the most significant issues to be addressed is the use of volatile organic compounds (VOCs) as solvents because they ...

Semiconductor-metal transition in semiconducting bilayer sheets of transition metal dichalcogenides

open access: yes, 2012
Using first-principles calculations we show that the band gap of bilayer sheets of semiconducting transition metal dichalcogenides (TMDs) can be reduced smoothly by applying vertical compressive pressure.

Modulation of the optical properties of transition metal doped PbSe quantum dots in silicate glasses

open access: yesMaterials Research Express, 2020
Optical properties of lead chalcogenide quantum dots (QDs) can be controlled by tuning its bandgaps. We prepared silicate glasses using the melt-quenching method and heat-treated 510 °C–540 °C for 10 h to precipitate transition metal ions into PbSe QDs ...

Magnetic interactions in transition metal doped ZnO : An abinitio study

open access: yes, 2006
We calculate the nature of magnetic interactions in transition-metal doped ZnO using the local spin density approximation and LSDA+\textit{U} method of density functional theory.

Superconductivity in transition metals [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015
A qualitative account of the occurrence and magnitude of superconductivity in the transition metals is presented, with a primary emphasis on elements of the first row. Correlations of the important parameters of the Bardeen–Cooper–Schrieffer theory of superconductivity are highlighted with respect to the number of d-shell electrons per atom of the ...

Insulator-Metal transition in the Doped 3d1 Transition Metal Oxide LaTiO3

open access: yes, 2003
The doping induced insulator-metal transition in $La_{1-x}Sr_{x}TiO_{3}$ is studied using the ab-initio LDA+DMFT method. Combining the LDA bandstructure for the actual, distorted structure found recently with multi-orbital DMFT to treat electronic ...
