The emperical pseudopotential method in the large basis approach was used to calculate
the electronic bandstructures of bulk semiconductor materials and layered semiconductor
heterostructures. The crucial continuous ...
Imaging techniques have been developed for decades for the detection of biomolecules in
biomedicine cells, in vitro or in living cells and organisms. The application however, often
constrained by the available probes, ...
Radionuclide liquid wastes generated from nuclear facilities can affect humans and the environment, thus substantial attention for their safe management has been received worldwide. Treatment of radionuclide liquid wastes ...
In the present research we successfully synthesized NaAlSiO2 crystals and doped (co- doped) them with various concentrations of Er3+, and Yb3+ ions via a hydrothermal method to unveil their up-conversion absorption bands ...
Titanium dioxide (TiO2) nanostructures were synthesized by sol-gel method and co polymers polyethylene glycol (PEG), polyvinylpyrrolidone (PVP) and pluronic F127
were used as pore forming agents. The samples were then ...
Deuteration is the replacement of a hydrogen atom by deuterium atom in a molecule. The replacement begins at the most acidic hydrogen in the molecule. In ATP, the deshielded hydrogen is C8-H which is the first replaced ...
Mathematics plays a pertinent role in physics. Students' understanding of this role has significant implications in their understanding of physics. Studies have shown that some students prefer the use of mathematics in ...
Bound state systems consisting of three nonrelativistic particles are numerically
studied. Calculations are performed employing two-body and three-body forces as
input in the Hamiltonian in order to study the role or ...
Hidden sector or dark sector states appear in many extensions to the Standard
Model (SM), to provide particle mediators for dark matter in the universe or to
explain astrophysical observations such as the positron excess ...
1720 MHz OH masers have been detected towards a number of supernova remnants (SNRs) at the shock interface where the SNR slams into the interstellar medium. Models indicate that these masers are shock excited and can only ...
In this contribution the sinc basis functions are used to numerically solve the
Schrödinger equation in one and two dimensions for a number of potentials.
The calculations are done using the Python and Numpy modules. ...
NaYF4:Yb3+/Er3+ and NaGdF4:Yb3+/Nd3+ nanocrystals were prepared using a solution combustion (SC) method and their properties were evaluated for potential use as photon harvesters in photovoltaic solar cells (PSCs). The ...
The objective of this study was to investigate whether community print media is fulfilling its developmental mandate in society using a comparative study of Alex News and Greater Alex Today community newspapers. This study ...
Polycrystalline Zn1-xCrxO (0.01 ≤ x ≤ 0.09) samples synthesized by solid state reaction technique were sintered at different temperatures following slow step sintering schedule. Structural, micro-structural, optical, ...
A two-dimensional integrodi erential equation resulting from the use of potential harmonics
expansion in the many-body Schr odinger equation is used to study ground-state
properties of selected few-body nuclear systems. ...
Un-doped, Er3+ doped (TiO2:Er3+) as well as Er3+/Yb3+ co-doped (TiO2:Er3+/Yb3+) nanocrystals with different concentrations of RE3+ (Er3+, Yb3+) were successfully synthesized using the sol-gel method.
The powder X-ray ...
The development of cost-effective and scalable synthetic methods is of paramount importance
to achieve industrial application of energy conversion and storage devices based on layered
double hydroxides (LDH). Herein, ...
In this work, alkaline earth aluminate phosphors doped with rare-earth ions and manganese were
synthesized using combustion method. Several characterization techniques were used to study
the structural and luminescent ...
