A single liquid chromatography procedure to concentrate, separate and collect size-selected polyynes produced by pulsed laser ablation in water

Liquid-Phase Pulsed Laser Ablation

Enhancement of pulsed laser ablation in environmentally friendly liquid.

Enhancement of pulsed laser ablation can be achieved in acetic acid as an environmentally friendly liquid. This paper evaluates microholes and textured features induced by a nanosecond pulsed laser under different processing circumstances. The microholes are fabricated by laser drilling in acetic acid and found to be 100% deeper than in air. The textured features achieved in the liquid demonstr...

Nonstoichiometric Titanium Oxides via Pulsed Laser Ablation in Water

Titanium oxide compounds TiO,Ti2O3, and TiO2 with a considerable extent of nonstoichiometry were fabricated by pulsed laser ablation in water and characterized by X-ray/electron diffraction, X-ray photoelectron spectroscopy and electron energy loss spectroscopy. The titanium oxides were found to occur as nanoparticle aggregates with a predominant 3+ charge and amorphous microtubes when fabricat...

Acute toxicity of synthetic colloidal silver nanoparticles produced by laser ablation method to Eastern mosquitofish, Gambusia holbrooki

Considering the growing production, consumption of nanomaterials and their probable release into the aquatic ecosystems and study on the toxic effects of these materials are of critical importance to aquatic organisms. In this study, the acute toxicity of silver nanoparticles (AgNPs) produced by a physical method (laser ablation) was examined on Gambusia fish. Acute toxicity tests were planned ...

Nickel ferrite Nanomaterials by Pulsed laser ablation in Water; Structural, Optical and Magnetic Characterizations

Nickel ferrite nanoparticles are synthesized by pulsed laser ablation of corresponding bulk target in the double distilled water. Focused output of fundamental and third harmonics from pulsed Nd:YAG laser operating at 40 and 25 mJ/pulse energy respectively was allowed to irradiate the target. Produced colloidal solution was red in color and stable for several days. XRD, FTIR, VSM techniques are...
