The photocatalytic efficiency of low cost TiO2 thin layers for discoloration of methylene blue
TiO2 thin films were fabricated on glass substrates via a low-cost sol–gel spin-coating route and annealed between room temperature and 400 °C to elucidate the influence of thermal treatment on structure–property–photocatalytic performance relationships. X-ray diffraction and Raman analyses…

Multi-channel SERS enhancement using graphene-based trimeric molecule in triangular configuration
In this paper, a graphene-based trimeric plasmonic molecule with a triangular configuration is proposed for the multi-channel surface-enhanced Raman scattering (SERS). It is observed that the equilateral triangular nanoparticle arrangement provides multiple intense resonance channels with giant…

Multi-objective time-domain adjoint via temporal convolution for band-selective electromagnetic topology optimization
Adjoint-based topology optimization enables gradient computation for electromagnetic design from only two simulations, independent of problem size. Conventional frequency-domain adjoint methods suit single-frequency objectives but incur computational costs scaling linearly with spectral resolution…

Contribution in exciton, donor and acceptor energy determining in a high-purity ZnS vapor-deposited layer
A thin layer of a high quality ZnS grown on a GaAs (001) substrate by MOCVD at 350°C and characterized by photoluminescence (PL) at 20 K and reflectivity (at 20 K) allowed us to determine the energy of free and bound excitons as well as those of the impurities present in our ZnS. By reflectivity we…

Using autoencoder feature compression combined with deep neural networks for precise radioisotope identification in composite spectra
Accurate and rapid identification of radioactive isotopes from short-duration and low-count γ-ray spectra is critical for nuclear security, environmental monitoring, and emergency response. We present a two-stage deep-learning framework combining an autoencoder for unsupervised feature compression…

Investigating performance metrics in high volumetric utilization betavoltaic convertors: A Monte Carlo and analytical approach
Due to their low active volume, betavoltaic cells, especially those with low-energy beta sources, are often inefficient in applications that require high power density. Incorporating auxiliary side sources into high volumetric utilization structures can improve open-circuit voltage, short-circuit…

Localization–delocalization transition in the Generalized Aubry–André–Harper Model in a quasiperiodic superlattice potential
We investigate localization–delocalization transition in the one-dimensional generalized Aubry–André–Harper (GAAH) model in a quasiperiodic superlattice potential. The critical interplay between the model’s two modulated energy scales — the hopping amplitude (t) and the on-site potential (Δ) —…

Hardy’s non-locality in four-qubit state
Hardy’s non-locality provides a proof of the incompatibility between quantum mechanics and local realism without using Bell inequalities. While this argument has been extensively studied for two- and three-qubit systems, a detailed analysis of the four-qubit case is still lacking. In this work, we…

A comparative study of correlation and relativistic effects on atomic ionization energy
This study investigates the interplay between relativistic effects and electron correlation effects on the first ionization energies of heavy atoms (Au through Rn, Z = 79–86). We perform two complementary analyses: (1) comparing relativistic corrections computed at both the Hartree-Fock (HF) and…
