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 ...
This thesis investigates why there is still no ‘final’ physical theory of the universe despite the enormous resources involved. Current physical and philosophical methodologies are examined leading to a new strategy. The ...
The few-body integrodifferential equations are approximations to the few-body Schr¨odinger
equation in hyperspherical coordinates. The few-body integrodifferential equations for
identical particles reduce to a single ...
Modern memory devices such as static random-access memory (SRAM),
dynamic random-access (DRAM), and Flash memories demonstrated inevitable
limitations, i.e., large cell size (50 − 120 F2) of SRAM, accompanied
by current ...
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 ...
Supercapacitors are promising energy storage devices which fill the gap between conventional
capacitors and batteries. They possess several advantages compared to the latter such as safe
operation, superior capacitance ...
The undoped SrSiO3/SiO2 phosphors prepared by both co-precipitation and
hydrothermal methods at different Sr/Si molar ratios are reported. Undoped and
Mn doped BaAl2O4 phosphor synthesized using combustion method are ...
In this research work, metal-doped MoS2 of Cobalt and Manganese (Co-MoS2 and Mn-MoS2) nanocomposites of different ratios of dopant concentrations were synthesized with a facile hydrothermal technique. The samples were ...
The effective implementation of inquiry-based practical work poses an enormous challenge, especially in Township and rural schools. The challenges stem from the teachers’ diverse understanding of inquiry-based strategy. ...
Abstract
The contamination of environmental waters with heavy metals and radionuclides is increasing because of rapid industrial and population growth. The removal of these contaminants from water via ...
The original two-variable integrodifferential equation for few-body systems is mod ified by introducing boundary conditions in the radial and angular domains. The
accuracy of the adiabatic approximation in solving this ...
The physics of loosely-bound and halo nuclei is very important in the enhancement
of knowledge about the complete nature of strong interactions in general, and nuclear
forces in particular. Although such nuclei are widely ...
Substantial progress has been made in the studies of loosely-bound nuclei, however there are many issues about the properties of these nuclei that have not been resolved yet. For example nuclear decay, nuclear reactions ...
In this work we analyse fusion cross-section (σF ) in different projectile target systems.
Collision systems can result in different reactions such as elastic/ inelastic scattering, fu sion and fission reactions to name ...
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. ...
Rural and urban learners from primary and secondary schools participate in science fairs all over the world, but their performance differs. To investigate the dynamics influencing the performance of rural and urban learners ...
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 ...
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, ...
