magnesium hydroxide nanostructures as an effective flame retardant were synthesized by a facile and rapid microwave reaction. the effect of different surfactants such as cationic, anionic and polymeric on the morphology of magnesium hydroxide nanostructures was investigated. nanostructures were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem) and fourier transform in...

tm3+, yb3+ and tm3+/yb3+ doped lavo4 nanostructures were synthe-sized for the first time by using the hydrothermal method with the aid of la(ch3co2)3 as  lanthanum source in presence of oleic acid as surfactant. the products were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem), transmission electron microscopy (tem), photoluminescence (pl) spectroscopy and uv–vis di...

Title of Document: FAILURE MECHANICS OF FUNCTIONAL NANOSTRUCTURES IN ADVANCED TECHNOLOGIES Zheng Jia, Doctor of Philosophy, 2014 Directed By: Associate Professor Teng Li, Department of Mechanical Engineering The past decade has seen a surge of interest in developing novel functional nanostructures to enable advanced technologies, such as flexible electronics and high performance lithium-ion bat...

the current study reports some interesting growth of novel in2o3 nanostructures using ambient-controlled chemical vapor deposition technique in the presence of a strongly reducing hydrazine ambient. the experiments are systematically carried out by keeping either of the carrier gas flow rate or the source temperature constant, and varying the other. for each of the depositions, the growth is st...

various morphologies of silica nanoparticles were synthesized by a microwave-assisted pechini method. silica nanostructures were synthesized via a fast reaction between tetra ethyl ortho silicate and ammonia at presence citric acid and other effective agents in pechini procedure. then for preparation of polymer-matrix nanocomposites, sio2 nanoparticles were added to poly carbonate (pc) and poly...

We report the synthesis of compositionally asymmetric, core-Janus shell plasmonic nanostructures comprised of Au and Ag. Kinetic control was employed to achieve asymmetric shell growth on Au nanoparticles acting as cores. Subsequent differential surface functionalization of these nanostructures enabled programmed shell growth resulting in core-Janus shell nanostructures. UV/vis extinction spect...

Present work focuses on the synthesis strategies for different CuO nanostructures along with associated formation mechanisms and their interesting fundamental properties, and promising applications in biological and environmental remediation. We present a variety of synthesis techniques for producing diverse types of CuO nanostructures with various morphologies such as nanoparticles, nanoleaves...

Synthetic nanostructures, such as nanoparticles and nanowires, can serve as modular building blocks for integrated nanoscale systems. We demonstrate a microfluidic approach for positioning, orienting, and assembling such nanostructures into nanoassemblies. We use flow control combined with a cross-linking photoresist to position and immobilize nanostructures in desired positions and orientation...
