Preparation of SERS Substrates for the Detection of Organic Molecules at Low Concentration
Tập 26 Số 3 - 2017
In this paper, we present the results of the preparation of Surface Enhanced Raman Spectroscopy (SERS) substrates by depositing silver nanoparticles (Ag NPs) onto a porous silicon wafer that is produced by the chemical etching process. The influences of the preparation parameters such as resistivity of the silicon wafer, the anodizing current density, etching time to the size of pores were systema......

Controllable Optical Properties of Multiple Electromagnetically Induced Transparency in Gaseous Atomic Media
Tập 29 Số 1 - 2019
The advent of electromagnetically induced transparency (EIT) offered a new coherent material with exotic and controllable optical properties. Although, studies on single-EIT are described in detail for single-EIT, however, extension from single- to multi- EIT is currently of current interest due to it gains advantages in multi-channel optical communication, waveguides for optical signal processing......

Hydrothermal Synthesis and Optical Properties of Undoped and \(\text{Eu}^{3+}\)-doped Zinc Stannate Nanocrystals
Tập 25 Số 4 - 2016
Abstract. In this work we report a hydrothermal approach for synthesis of zinc stannate (Zn2SnO4)nanocrystals. Our research focused on the effect of the molar ratio of initial chemicals, reaction temperature and reaction duration on the phase composition and the fluorescence properties.Structural and optical properties of the final products were investigated in detail. X-ray diffractionanalysis in......
Tungsten Oxide Nanoplates: Facile Synthesis, Controllable Oxygen Deficiency and Photocatalytic Activity
Tập 30 Số 4 - 2020
Monoclinic tungsten oxide (WO3) nanoplates were synthesized via a two-step simple process: acid precipitation at room temperature to prepare WO3.H2O nanoplates and annealing at high temperature (400 and 500 oC) in ambient air to obtain WO3 nanoplates. The effect of annealing temperature on physical properties (morphology, oxygen deficiency, crystallinity, optical properties, and photocatalytic act......

Enhancing the doubly-longitudinal polarization in WZ production at the LHC
Tập 33 Số 3 - 2023
We present new results for the theoretical prediction of doubly-polarized cross sections of $WZ$ events at the LHC using leptonic decays. Compared to the previous studies, two new kinematic cuts are considered. These cuts are designed to enhance the doubly-longitudinal (LL) polarization and, at the same time, study the Radiation Amplitude Zero effect. We found a new cut on the rapidity separation ......
Equivalence Between Vector Meson Dominance and Unitarised Chiral Perturbation Theory
Tập 24 Số 4 - 2015
It is explicitly shown that either the approximate solution of the integral equation for the inverse of the pion form facto,r or the result of the Pad\(\text{\'e}\) approximant method of resumming the one loop Chiral Perturbation Theory (CPTH) are equivalent to the standard vector meson dominance (VMD) models, using the vector meson coupling to two pseudoscalars given by the KSRF relation. Inc......
A Low Cost Microwave Synthesis Method for Preparation of Gold Nanoparticles
Tập 24 Số 2 - 2014
The gold nanoparticles (GNPs) in 15-20 nm size range have attracted attention for fabrication of smart sensing devices in biomedical sciences as diagnostic tools. Citrate capped GNPs are negatively charged, which can be exploited for electrostatic interactions with some positively charged biomolecules like antibody. In this study, we are developing a low-cost technique by using a common microwave ......

Was the Higgs Boson Discovered?
Tập 25 Số 1 - 2015
The standard model has postulated the existence of a scalar boson, named the Higgs boson (or the Brout-Englert-Higgs boson, for more complete). This boson plays a central role in a symmetry breaking scheme called the Higgs mechanism making the standard model realistic. However, until recently at least, the 50-year-long-sought Higgs boson had remained the only particle in the standard model not yet......
Binding Energy of Exciton in Quantum Dots with the Central-cell Correction Depending on the Dot Sizes
Tập 31 Số 2 - 2007
The binding energy of exciton in quantum dots with a parabolic
confinement potential was calculated by variational methods beyond the Kohn-Luttinger effective mass theory, when the central-cell correction was taken into account.We have assumed that a short range potential with two parameters for strength and range for exciton, representing the center-cell effect also depends on dot size. Our resu......
Anomalous Magnetic Dipole Moment \((g-2)\mu\) in 3-3-1 Model with Inverse Seesaw Neutrinos
Tập 30 Số 3 - 2020
We will show that the recent experimental value of the anomalous magnetic moment (AMM) of the charged lepton m , denoted as \(a_mu (g-2)\mu/2\), can be explained successfully in a 3-3-1 model with right handed neutrino adding new heavy \(SU (3)_L\) neutrinos singlets. Allowed regions satisfying the recent AMM data are illustrated numerically.
