Microstructure and luminescent properties of Eu3+-activated MgGa2O4:Mn2+ ceramic phosphors
Journal of Advanced Ceramics, 2020 Mn2+ and the trivalent europium (Eu3+)-doped MgGa2O4 ceramics are characterized using a multi-experimental approach. The formation of spinel-structured ceramics is ascertained from X-ray diffraction (XRD) analysis.

Annalen der Physik, Volume 538, Issue 1, January 2026.The BRST invariant Lagrangian of the gravitationally interacting U(1)$U(1)$ gauge theory, namely the Quantum GraviElectro Dynamics (QGED). The Yan–Mills theory with the Hilbert–Einstein gravitational Lagrangian, namely the Yang–Mills–Utiyama (YMU) theory, is defined and quantised using the standard procedure. The theory is perturbatively renormalisable,

Fermi surface determination from momentum density projections
New Journal of Physics, 2016 The problem of determining a metal’s Fermi surface from measured projections of the electron or electron/positron momentum densities, such as those obtained by Compton scattering or angular correlation of positron annihilation radiation, respectively, is

Soft-drop event shapes in electron–positron annihilation at next-to-next-to-leading order accuracy
Physics Letters B, 2018 We present predictions for soft-drop event shapes of hadronic final states in electron–positron annihilation at next-to-next-to-leading order accuracy in perturbation theory obtained using the CoLoRFulNNLO subtraction method.

Физика волновых процессов и радиотехнические системы, 2014 The reasons of angular photon distribution occurrence at electron-positron annihilation are considered. It is shown, that angular photon distribution is consequence of Dopplers effect in the reference frame of the electron and positron mass center.

Positron Annihilation Studies on Chemically Synthesized FeCo Alloy
Scientific Reports, 2018 Equiatomic flower-like FeCo magnetic nanoparticles are synthesized through a modified one-pot polyol technique. The as-prepared samples are annealed at 700 and 800 °C under reducing atmosphere.

Catalytic Activity of Cobalt Ferrites in Water Oxidation Reactions and Its Defect Dependency
ChemCatChem, Volume 18, Issue 1, 15 January 2026.Cobalt ferrite spinels calcined at 400–600 °C show temperature‐dependent changes in crystallinity, particle size, and defect concentration. A combination of PXRD, BET, SEM, Mössbauer spectroscopy, magnetometry, and PALS reveals how defect landscapes govern opposing trends in chemical versus electrochemical water oxidation.

Double Charmonium Productions in Electron-Positron Annihilation Using Bethe-Salpeter Approach
Advances in High Energy Physics, 2019 We calculate the double charmonium production cross-section within the framework of 4×4 Bethe-Salpeter Equation in the electron-positron annihilation, at center of mass energy s=10.6GeV, that proceeds through the exchange of a single virtual photon.
