Red Light Emitting Transition Metal Ion Doped Calcium Antimony Oxide for Plant Growth Lighting Applications

open access: yesAgriculture, 2022
In this work, we synthesized Mn4+-doped CaSb2O6 phosphors using the conventional solid-state reaction method for plant growth lighting applications. The morphological, structural, and optical properties were analyzed based on the results obtained from ...

Metal Polysulfides as High Capacity Electrode Active Materials — Toward Superior Secondary Batteries Based on Sulfur Chemistry

open access: yesElectrochemistry, 2023
Lithium/transition-metal polysulfide batteries are a promissing candidate for next-generation batteries with high energy densities. Transition metal polysulfides and lithium- or sodium-containing transition metal sulfides exhibit large reversible ...

Charge order, orbital order, and electron localization in the Magneli phase Ti4O7 [PDF]

open access: yes, 2004
The metal-insulator transition of the Magneli phase Ti4O7 is studied by means of augmented spherical wave (ASW) electronic structure calculations as based on density functional theory and the local density approximation.

Metal-Insulator Transition from Graphene to Graphane

open access: yesNanomaterials and Nanotechnology, 2013
Graphane is obtained by perfectly hydrogenating graphene. There exists an intermediate material, partially hydrogenated graphene (which we call hydrographene), interpolating from pure graphene to pure graphane.

First-Principles Electronic-Structure Study of Graphene Decorated with 4d-Transition Atoms

open access: yesCrystals, 2020
Adsorption configurations, electronic structures and net spins of graphene adsorbing 4d transition atoms are calculated by first-principles calculations to explore the magnetic modification of decorating metal atoms on graphene. Y, Zr and Nb atoms can be

Epitaxial growth of higher transition-temperature VO2 films on AlN/Si

open access: yesAPL Materials, 2016
We report the epitaxial growth and the mechanism of a higher temperature insulator-to-metal-transition (IMT) of vanadium dioxide (VO2) thin films synthesized on aluminum nitride (AlN)/Si (111) substrates by a pulsed-laser-deposition method; the IMT ...

Iron in intracellular infection: to provide or to deprive?

open access: yesFrontiers in Cellular and Infection Microbiology, 2013
Due to their chemical versatility, transition metals were incorporated as cofactors for several basic metabolic pathways in living organisms. This same characteristic makes them potentially harmful, since they can be engaged in deleterious reactions like

Hydrogenation of CO2 or CO2 Derivatives to Methanol under Molecular Catalysis: A Review

open access: yesEnergies, 2022
The atmospheric CO2 concentration has been continuously increasing due to fossil fuel combustion. The transformations of CO2 and CO2 derivatives into high value-added chemicals such as alcohols are ideal routes to mitigate greenhouse gas emissions. Among
