Temperature Gradient: A Simple Method for Single Crystal Growth
- 2019
Abstract: In this article, we provide a simple method for the growth of bulk
single crystalline. By the control temperature along a vertical furnace, we can
easily fabricate bulk single crystals. This technique is called the temperature
gradient method. To create a temperature gradient along the body of the furnace,
the density of resistance wire which is coiled along the body of furnace is
differ...
The Influence of the Anomalous Coupling on the in the Randall - Sundrum Model
Tập 40 Số 4 - Trang - 2024
A study to produce a Z boson and a radion through anomalous couplings is
considered from muon-muon colliders at the center of mass energy 10 TeV. The
leptonic decays of the Z boson and a radion decaying into a pair of photons are
considered. The integrated luminosity of muon colliders is 10 . The production
cross-sections depend on the polarization of initial beams, the center of mass
energy . Th...

Synthesis of Tungsten Oxide Nanofibers Using Electrospinning Towards Gas Sensor Application
Tập 41 Số 2 - Trang - 2025
A simple strategy was introduced to synthesize WO3 nanofibers through an
electrospinning process. In this work, tungstic acid, hydrogen peroxide and
polyvinyl pyrrolidone were used as precursors. After electrospinning and drying
the desired material was collected. The morphology and structure of the samples
were analyzed by field-emission scanning electron microscopy (FESEM),
energy-dispersive x-r...
Zeta Potential Measurement Using Streaming Potential in Porous Media
- 2015
Electrokinetic phenomena are induced by the relative motion between a fluid and
a solid surface and are directly related to the existence of an electric double
layer between the fluid and the solid grain surface. Electrokinetics in porous
media plays an important role in geophysical applications and environmental
applications. The zeta potential is one of the key parameters in
electrokinetics. The...
A Comparison Study of Photocatalytic Performance of TiO2 Anatase Phase Prepared from Different Procedures
Tập 40 Số 3 - Trang - 2024
In this work, three TiO2 anatase phase samples, labeled as S1, S2, and S3, were
synthesized using varying titanium precursors, solvents, and conditions to
compare their photocatalytic performances. The structural and morphological
properties of the synthesized samples were characterized through X-ray
diffraction (XRD), Raman scattering, field emission scanning electron microscopy
(FESEM), and tran...
Structural Properties of Amorphous Vanadium Pentoxide Under Compression
Tập 40 Số 2 - Trang - 2024
Structural properties of amorphous vanadium pentoxide (V2O5) under compression
have been investigated by molecular dynamics simulation. A simulated amorphous
V2O5 was composed of basic structural units of type VO5, VO6 at low-pressures
and VO6, VO7 at high-pressures. These basic structural units were connected by
vertex-, edge- and face- shared links to form a structural network. The random
distr...
