Rapid Synthesis of Gold Nanoparticles without Heating Process

Femtosecond-pulsed optical heating of gold nanoparticles

Green Synthesis of Gold Nanoparticles

Nanotechnology has emerged as the interdisciplinary science conjugating the basic concept of engineering with the application of biology, chemistry, physics and medical science1. Research in the field of synthesis of nanoparticles has been growing dramatically over the last few decades due to their unusual and highly interesting properties with wide potential applications like antifungal activi...

FEM Analysis of Laser-Induced Heating of Gold Nanoparticles

Nanoparticles are being extensively researched as a noninvasive method for selectively targeting and killing cancer cells. We present a method for modeling the thermal activation of a gold nanoparticle and the thermal response of its surrounding medium under single and multi-pulse excitation. It is found that the effective heating range of a nanoparticle is determined by both shape (sphere vs. ...

Nanoscale heating of laser irradiated single gold nanoparticles in liquid.

Biological applications where nanoparticles are used in a cell environment with laser irradiation are rapidly emerging. Investigation of the localized heating effect due to the laser irradiation on the particle is required to preclude unintended thermal effects. While bulk temperature rise can be determined using macroscale measurement methods, observation of the actual temperature within the n...

Synthesis of Ti4O7 Nanoparticles by Carbothermal Reduction Using Microwave Rapid Heating

The polymer electrolyte fuel cell (PEFC) is an attractive power generation method from the perspective of environmental protection. Carbon is usually used as a catalyst support in PEFC, but it is oxidized under high electrical potential conditions. Ti4O7 is expected as a new catalyst support because of its high electrical conductivity and chemical resistivity. Though Ti4O7 as a catalyst support...
