Choice of precursor not affecting the size of anatase TiO2 nanoparticles but affecting morphology under broader view
International Nano Letters - Tập 4 - Trang 1-8 - 2014
In this study, anatase titanium dioxide nanoparticles were successfully prepared
by a sol–gel method using two different precursors, titanium isopropoxide and
titanium butoxide. Hydrochloric acid or nitric acid was added to adjust the pH
of the solution. The sols obtained were dried at 80 °C and calcined at 450 °C
for 3 h. The nanostructures were characterised by scanning electron microscopy,
FTIR...
Effects of multi-walled carbon nanotubes on flame retardation and thermal stabilization performance of phosphorus-containing flame retardants in polypropylene
International Nano Letters - Tập 2 - Trang 1-7 - 2012
Effects of multi-walled carbon nanotubes (MWNTs) on flame retardation as well as
thermal stabilization efficiency of two phosphorus-containing flame retardant
systems i.e., ammonium polyphosphate/pentaerythritol (APP/PER) and red
phosphorus (RP) in polypropylene (PP) have been investigated. Limiting oxygen
index, thermo-gravimetric analysis, melt flow index, and tensile tests have been
performed i...
Facile synthesis and characterization of TiO2 nanoparticles: X-ray peak profile analysis using Williamson–Hall and Debye–Scherrer methods
International Nano Letters - Tập 11 - Trang 241-261 - 2021
In this study, TiO2 nanoparticles were synthesized by a sol–gel method involving
the interaction of the titanium isopropoxide precursor and sodium hydroxide
followed by calcination at a temperature of 450 °C. The effects of stirring time
and solution pH on the morphology, phase types and crystallite sizes were
investigated. The prepared TiO2 nanoparticles were characterized using X-ray
diffraction...
Recent progress in algae-mediated silver nanoparticle synthesis
International Nano Letters - Tập 13 - Trang 193-207 - 2022
The use of silver nanoparticles (AgNPs) in many consumer products is expected to
increase in the future due to their multifaceted properties. With the increasing
demand for AgNPs, manufacturers are focusing more on exploring various methods
for synthesizing AgNPs that are safer, cost-effective, and scalable. Synthesis
of AgNPs using biological processes is advantageous over physical and chemical
m...
Biogenic synthesis of magnesium oxide nanoparticles using Manihot esculenta (Crantz) leaf extract
International Nano Letters - Tập 10 - Trang 43-48 - 2019
Recently, plant-mediated route or green approach for preparing metal and metal
oxide nanoparticles has received enormous attention due to the ease of
preparation and environmental friendliness when compared to physical and
chemical methods. Plants contain phytochemicals which have been proposed as
bio-reductants and capping agents for forming metal nanoparticles. Therefore,
this study was aimed to...

Hydrothermal synthesis and investigation of optical properties of Nb5+-doped lithium silicate nanostructures
International Nano Letters - Tập 4 - Trang 1-9 - 2014
The hydrothermal synthesis and optical properties of Nb5+-doped lithium
metasilicate and lithium disilicate nanomaterials were investigated. The
microstructures and morphologies of the synthesized Li2 -2x Nb2x SiO3 + δ and
Li2 -2x Nb2x Si2O5 + δ nanomaterials were studied by powder X-ray diffraction
and scanning electron microscopy techniques, respectively. The synthesized
niobium-doped lithium me...
Controlled synthesis of ZnO nanoparticles and evaluation of their toxicity in Mus musculus mice
International Nano Letters - Tập 8 - Trang 165-179 - 2018
Zinc oxide nanoparticles (ZnO-NPs) of different sizes and morphology were
synthesized. The variables analyzed were zinc precursor concentration, the
nature of the synthesis solvent and the concentration of surfactant agent. The
solids synthesized were characterized using IR spectroscopy, X-ray diffraction
(XRD) and transmission electron microscopy (TEM). Considering the nature of the
synthesis pro...
