We discuss the atomic structure of cobalt ferrite nanoparticles doped with Mn via an analysis based on combining atomic pair distribution functions with high energy X-ray diffraction and high-resolution transmission electron microscopy measurements.

Abstract At present, the measurements of R D ∗ $$ {R}_{D^{\left(\ast \right)}} $$ and R J/ψ hint at new physics (NP) in b → c τ − v ¯ $$ b\to c{\tau}^{-}\overline{v} $$ decays. The angular distribution of B ¯ → D ∗ → Dπ τ − v ¯

Abstract In order to explain the observed anomalies in the measurements of R D ∗ $$ {R}_{D^{\left(\ast \right)}} $$ and R J/ψ , a variety of new-physics (NP) models that contribute to b → c τ − ν ¯ $$ b\to c{\tau}^{-}\overline{\nu} $$ have

We present a dark sector model that reproduces the KOTO, MiniBooNE and muon anomalous magnetic moment anomalies. The dark sector is comprised of a light scalar singlet S that has a large coupling to a slightly heavier sterile neutrino that mixes with

Lightweight steel construction has some undeniable advantages over concrete construction; however, reinforced concrete structures are used ubiquitously in Mediterranean countries and therefore most of the scientific studies have been focused on the r

Abstract In a recent paper we studied the effect of new-physics operators with different Lorentz structures on the semileptonic Λ b → Λ c τ ν ¯ τ $$ {\Lambda}_b\to {\Lambda}_c\tau {\overline{\nu}}_{\tau } $$ decay. This decay is of interest i

The structure of nanoparticles has been difficult to determine accurately because the traditional structure methods rely on large monocrystals. Here, we discuss the structure of nanoparticles based on real-space modeling of the pair distribution func

The optimal modes (temperature, time, pressure force) of spark plasma sintering (SPS) and hot pressing of boron carbide obtained by various methods are determined. The initial powders were obtained from soot and amorphous boron by the mechanochemical

In this paper, we present the development of new types of boron carbide-based ceramics. Boron carbide is applied in the electronics and nuclear industries as well as for production of the grinding and abrasive materials, protective plates for body ar
