The main purpose of this work is to study the effectiveness of using FeCeOx nanocomposites
doped with Nb2O5 for the purification of aqueous solutions from manganese. X-ray diffraction,
energy–dispersive analysis, scanning ...
The novelty of the study is that the ordering that occurs in a PET film under the action of
SHI irradiation manifests itself as an increase in the integral intensity of intrinsic luminescence. The
Urbach behaviour of the ...
The creation of a combined radiative state at 2.95–3.1 eV in the phosphor CaSO4 − Dy3+
has been investigated using vacuum ultraviolet and thermoactivation spectroscopy methods. It is
shown that the combined radiative ...
The emotional speech recognition method presented in this article was applied to recognize
the emotions of students during online exams in distance learning due to COVID-19. The purpose of
this method is to recognize ...
This study considers the effect of various doses of electron irradiation on the crystal structure
and properties of composite catalysts based on polyethylene terephthalate track-etched membranes
and copper nanotubes. ...
This research investigated how changes in the composition of Nb–Ti–V–Zr-based alloys
affect their resistance to radiation damage and the preservation of strength characteristics when
exposed to the heavy ions Kr15+ and ...
The effects of residual radiation from atomic bombs have been considered to be minimal
because of its low levels of external radioactivity. However, studies involving atomic bomb survivors
exposed to only residual radiation ...
It has been shown that there exist conditions under which thermosensitive copolymers
of N-vinylpyrrolidone with methyl acrylate form hydrophobic–hydrophilic associations, which are
unstable dynamic meshes, the bonds in ...
In the present work, we investigate the potential of modified barium titanate (BaTiO3
), an
inexpensive perovskite oxide derived from earth-abundant precursors, for developing efficient water
oxidation electrocatalysts ...
Silicon nitride, silicon oxide, and silicon oxynitride thin films
were deposited on the Si substrate by inductively coupled plasma chemical
vapor deposition and annealed at 1100 °C for 3 min in an Ar environment.
Silicon ...
Quantum-confined CdTe nanoplatelets (NPL) are synthesized in colloidal solutions. The
formation, growth, and transformation of 2D NPLs are monitored using UV-visible absorption PL
spectroscopy and transmission electron ...
Tastulekova, A.B.; Satova, R.K.; Shalbolova, U.Zh.(European Research Studies Journal, 2018)
The economic independence of any state is the basis of the welfare of the country’s
population. Starting from 2011, the Republic of Kazakhstan has been working on the
financial stabilization of its core assets by ...
The paper is devoted to the study of radiation-induced damage kinetics in beryllium
oxide ceramics under irradiation with low-energy helium ions with fluences of 1015–1018 ion/cm2
.
It was revealed that at irradiation ...

This paper describes the desalination process by membrane distillation (MD) using track-etched
membranes (TeMs). Hydrophobic track-etched membranes based on poly(ethylene terephthalate) (PET
TeMs) with pore diameters ...
This paper considers an approach
to resolving referential relations
when extracting information from a
text. The proposed approach is an
attempt to integrate the multifactorial
model of the activation coefficient
with ...
In this study, copper (Cu) and nickel oxide (Ni2O3) microtubes (MTs) were synthesized using an electroless
template deposition technique within porous polycarbonate (PC) track-etched membranes (TeMs) to
obtain Cu@PC and ...
The use of nitride ceramics, in particular AlN, as structural materials for nuclear power is
primarily limited by their resistance to swelling and hydrogenation processes due to the accumulation
of poorly soluble helium ...
The current stage of distance education development demands enhancement of standards for training of teachers working in that area. Only professional teachers are able to provide quality education for people with different ...
