All-inorganic Pb–Cd mixed-cation halide perovskites have emerged as semiconductors exhibiting improved optical and optoelectronic properties. We establish a reliable correlation between photoluminescence and Cd content x in bulk CsPb1−xCdxBr3 compositions, propose pathways of photoexcited charge carrier dynamics in them, and show improved stability of lasing in whispering gallery mode microdisks.

In this article, we investigate wave packet and solitary wave dynamics in the Whitham–Ostrovsky (WO) equation. By means of a multiple-scales expansion, we formally derive a nonlinear Schrödinger (NLS) equation governing the envelope evolution.The corresponding modulational stability diagram is then obtained using the Lighthill criterion. We show that sufficiently large values of the low-frequency dispersive term render ...

Lemon grass (Cymbopogon citratus, LG-SiO2), horsetail (Equisetum debile, SG-SiO2), and cassava leaves (Manihot esculenta, CL-SiO2) were used to green-synthesize silica (SiO2) nanoparticles (NPs). While LG-SiO2 and SG-SiO2 had strong (101) peaks and a large 22° amorphous peak, XRD of CL-SiO2 verified crystallinity. LG-SiO2 (agglomerated porous), SG-SiO2 (rectangular-cube agglomerates), and CL-SiO2 (flake agglomerates) had different morphologies. The TEM image of LG-SiO2 revealed agglomerated ...

Rational design of gold-based nanocarriers for neurotherapeutics requires atomic-scale understanding of drug-material interactions. Density functional theory calculations were performed to investigate levodopa (L-DOPA) adsorption on small gold clusters (Au2–Au4) with cationic, neutral, and anionic charges, with additional validation on a larger Au10 cluster using multiple low-energy isomers. Binding free energies (ΔGbind), charge transfer, and electronic descriptors ...

The shape of the heliosphere, regarded as comet-like since the 1960s, has recently been the subject of intense debate in the last decade. There is disagreement as to whether the heliospheric tail extends to ∼10,000 au in a comet-like shape or if it is short (∼400 au) with a split. Energetic neutral atom (ENA) maps from ...

The τ-phase in Mn-Al-Ga alloys is a promising candidate for rare-earth-free permanent magnets. This study re-veals that the τ(γ₂)-phase in rapidly quenched Mn55Al36Ga9 ribbons contains a high density of dislocations, which
form antiphase boundaries (APBs). Using transmission electron microscopy and density functional theory, we
demonstrate that Mn atoms at these APBs couple antiferromagnetically. This antiferromagnetic interaction is
identified ...

In this study we revealed the effect of scandium doping on the electronic and superconducting properties of the MgB2 compound. Calculations demonstrate that Sc substitutes for Mg atoms, acting as an electron donor. Mg substitution diminishes the density of states in the σ-band and attenuates the electron–phonon coupling, thereby elucidating the reduction in critical temperature. Simultaneously, ...

Substantial energy loss at the wide-bandgap (WBG) perovskite/fullerene interface poses a fundamental bottleneck for efficient all-perovskite tandem solar cells (APTSCs). Surface defects of WBG perovskite are a known source of non-radiative recombination and have been well-passivated, but this interface still remains with low quasi-Fermi level splitting (QFLS) with considerable voltage loss.
