Effect of Fe Doping on the Structural, Morphological, Optical, and Magnetic Properties of Ca2InTaO6 Double Perovskite

open access: yesphysica status solidi (b), EarlyView.
Fe‐doped Ca2InTaO6 double perovskites are synthesized via solid‐state reaction and systematically investigated. Rietveld refinement confirms orthorhombic Pbnm structure, while optical studies reveal a bandgap narrowing from 3.31 to 2.84 eV. Photoluminescence spectra exhibit strong red emission at 671 nm with optimal intensity at 10 mol% Fe ...

A case study of temperature tendency mechanisms operating over northern Africa during and following midlatitude winter troughs

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
An Iberia‐Central Mediterranean trough sequence (7–10 February 2018) delivers anomalous low‐level temperature tendencies attributable to dynamics across most of northern Africa, with warming over northeastern Africa, especially 10–12 February into the eastern Sahel. An ECMWF product attributes the tendencies (see Figure).

Do Donors Provide Foreign Aid Based on Needs? An Analysis of Funding Flows to Higher Education During the Implementation of the SDGs

open access: yesSustainable Development, EarlyView.
ABSTRACT A key objective of the Sustainable Development Goals (SDGs) is to leave no one behind and support least developed and other fragile countries first. The same is an objective of the Development Assistance Committee (DAC) group of bilateral donors.
