Active metasurfaces designed to operate at optical frequencies are flat optical elements that can dynamic, subwavelength-scale wavefront control of reflected or transmitted light. The practical and fundamental power-hand...

In the paper InAs spherical quantum dots in a GaAs matrix were investigated. The energies of electrons and holes in single- and multi-band models (with strong, weak, and intermediate spin-orbit interaction) were calculat...

Structural and electronic characteristics of neutral and charged vacancies of cadmium and sulfur in CdS nanocrystals have been performed using the density functional method with hybrid exchange-correlation functional. To...

The new charge-transfer complexes (CT) of eleven Schiff1 bases molecules as n-electron donors with the acceptor 1,4-naphthoquinone were studied spectrophotometrically in chloroform solution. The physical constants (a,b,C...

In the search for new compounds for the treatment of Chagas disease, the cysteine protease cruzipain remains as one of the most attractive biomolecular targets for drug development. Thiosemicarbazones (TSCs) have been id...

The hybridization of multiple excitons in a heterobilayer composed of two transition metal dichalcogenides (TMDCs) based on strong light–matter interaction is interesting from the viewpoint of both fundamental research...

The development of efficient nonstoichiometric redox materials for solar-driven H₂O/CO₂ splitting via two-step thermochemical cycles requires optimization of redox thermodynamics, kinetics, and material stability. Th...

Abstract Angle-resolved photoemission spectroscopy is a powerful experimental technique for studying anisotropic many-body interactions through the electron spectral function. Existing attempts to decompose the spectral ...

The present work provides a parametric simulation tool to assist the experimental deposition of GaN and Ge-GaN material. For this purpose, a kinetic Monte Carlo (kMC) model was developed and implemented to simulate the d...

We report a coherent layer-by-layer build-up of high-order harmonic generation (HHG) in artificially stacked transition metal dichalcogenides (TMDC) crystals in their various stacking configurations. In the experiments, ...

Abstract By examining proportions of high‐energy strokes from the World Wide Lightning Location Network (WWLLN) between 60°S and 60°N, and high‐radiance events from the Lightning Imaging Sensor (LIS) between 38°N ...

Coronal mass ejections (CMEs) are eruptions originating from the solar corona, usually carrying a large amount of fast-flowing plasma into interplanetary space, accompanied by an enhanced magnetic field. CMEs can form sh...

The search for photons at EeV energies and beyond has considerable astrophysical interest and will remain one of the key challenges for ultra-high energy cosmic ray (UHECR) observatories in the near future. Several upper...

4-bromo-3,5-di(methoxy)benzoic acid (I) crystallizes in the monoclinic C2/c space group, a = 22.3405 (6) Å, b = 4.85142 (14) Å, c = 18.1583 (5) Å, β = 93.086 (2)°. The crystal structure shows head-to-head dimeric un...

The doping of semiconductors with magnetic impurities gives rise not only to a spin-spin interaction between quasifree carriers and magnetic impurities but also to a local spin-independent disorder potential for the carr...

When polymers are irradiated with heavy ions new chemical groups are created in a few microns of the material. The irradiation changed the polarity and wettability on the surface so that could enhance the biocompatibilit...

The triazine backbone serves as a crucial heterocyclic scaffold in the development of energetic materials due to its high nitrogen (52%) and energy content (223 kJ/mol). Additionally, it functions as an environmentally b...

Surface-enhanced infrared absorption (SEIRA) spectroscopy holds significant promise for chemical detection as it enables direct identification of distinct vibrational fingerprints of molecules. Traditionally, SEIRA has b...

The diversity of Type II supernovae (SNe II) is thought to be driven mainly by differences in their progenitor´s hydrogen-rich (H-rich) envelope mass, with SNe IIP having long plateaus (∼100 days) and the most massive...

La digitalización del mundo del trabajo es una arista ineludible a la hora de acercarnos a los modos de trabajar en la actualidad. Este artículo se propone indagar las percepciones sobre trabajo digital en la ciudad de...

Abstract Three chromophores 5a-c based on the diphenylamine (donor), thiazole (π-core) and acrylonitrile (acceptor) were synthesized and characterized by IR, NMR, MS analyses. The donor–acceptor chromophores 5a-c were...

Abstract Lithium metal batteries possess the high theoretical specific energy owing to the high theoretical specific capacity of lithium metal. However, practical implementations necessitate a reduction in both lithium m...
