Tuning the Magnetic Phase Transitions in TbMn2‐xTixSi2 (x = 0–0.3)

Advanced Physics Research, EarlyView.
ABSTRACT Magnetocaloric materials receive considerable attention as promising candidates for next‐generation energy‐efficient and environmentally benign solid‐state refrigeration technologies. These materials exhibit the magnetocaloric effect (MCE), whereby heat is absorbed or released upon the application or removal of a magnetic field. In this study,

Effect of Annealing Temperature on the Structural, Morphological, and Optical Properties of CdSeTe Nanoparticles for Optoelectronic Applications

Advanced Physics Research, EarlyView.
A correlation between thermal treatment and enhanced crystalline quality, surface morphology, and optical response. As annealing temperature increases, structural refinement (evidenced by phrase transition from hexagonal to cubic), and more defined morphology (seen via SEM), and improved optical absorption and bandgap tuning (UV–vis and PL spectra) are

Fully integrated content analysis in International Relations

, 2017
Content analysis has once again come to the forefront of discussions regarding methods in International Relations (IR). The first wave of content analysis in IR lasted from the 1940s to the 1960s and was marked by a commitment to quantitative and manual

First‐Principles Study of Structural, Mechanical, Electronic, Thermodynamical, and Optical Properties of XGaO2 (X = Rb and Cs): Unlocking Its Green Energy Potential

Advanced Physics Research, EarlyView.
This study employs density functional theory (DFT) to investigate the structural, mechanical, electronic, optical, and thermodynamic properties of RbGaO2 and CsGaO2. The calculated band structures and band‐edge positions indicate semiconducting behavior and favorable alignment for photocatalytic dye degradation and hydrogen evolution, highlighting ...

The coelurosaur theropods of the Romualdo formation, early Cretaceous (Aptian) of Brazil: Santanaraptor placidus meets Mirischia asymmetrica

The Anatomical Record, EarlyView.
Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.
