Preparation of SERS Substrates for the Detection of Organic Molecules at Low Concentration
Tập 26 Số 3 - 2016
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...

Facile Synthesis of Carbon Quantum Dots by Plasma-liquid Interaction Method
Tập 27 Số 4 - 2018
Carbon quantum dots (CQDs) are a novel type of fluorescent nano-materials with
various unique properties. They are recently attracting enormous interest due to
their superiority in water solubility, chemical inertness, low toxicity, ease of
functionalization as well as resistance to photo-bleaching and potential
applications in biomedical indication, photo-catalysis, energy conversion,
optoelectro...

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...

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...

Hydrothermal Synthesis and Optical Properties of Undoped and \(\text{Eu}^{3+}\)-doped Zinc Stannate Nanocrystals
Tập 25 Số 4 - 2015
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...

THERMOELASTIC DAMPING DEPENDING ON VIBRATION MODES OF NANO BEAM RESONATOR
Tập 25 Số 4 - 2015
The obtainable quality factor for a nano beam resonator is limited due to
internal damping such as thermoelastic damping. Therefore, understanding how
internal damping varies with the respective resonant modes is very important to
design a high performance nanoresonator. In this research, we investigate
thermoelastic damping depending on vibration modes of nano beam resonators using
finite element...

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 ...
