Hexagonal-close-packed, hierarchical amorphous TiO2 nanocolumn arrays: transferability, enhanced photocatalytic activity, and superamphiphilicity without UV irradiation.
TL;DR: A hexagonal-close-packed, hierarchical amorphous TiO2 nanocolumn array was fabricated by pulsed laser deposition (PLD) using a PS colloidal monolayer as a template under a high pressure (6.7 Pa) of background oxygen gas, suggesting that the surface area of theTiO2 is preferable to its crystal structure for enhancing photocatalytic activity.
Journal ArticleDOI
Gas temperature and electron temperature measurements by emission spectroscopy for an atmospheric microplasma
TL;DR: In this paper, a microplasma suitable for material processing at atmospheric pressure in argon and argon-oxygen mixtures is studied and the effect of power and oxygen content is also analyzed in terms of gas temperature and electron temperature.
Journal ArticleDOI
Method to determine argon metastable number density and plasma electron temperature from spectral emission originating from four 4p argon levels
TL;DR: In this paper, a simple model and method is proposed to determine argon metastable number densities and electron temperature with the assumption of a Maxwell-Boltzmann electron energy distribution.
Journal ArticleDOI
Development of wire spraying for direct micro-patterning via an atmospheric-pressure UHF inductively coupled microplasma jet
TL;DR: In this article, wire spraying for direct micro-patterning via an atmospheric-pressure inductively coupled microplasma (AP-ICMP) jet of 20-50 μm in diameter was developed.
Journal ArticleDOI
Pressure effect on ZnO nanoparticles prepared via laser ablation in water
TL;DR: In this article, laser ablation of metallic Zn in neat deionized water at pressures up to ∼31 MPa and at constant ablation time, fluence, and wavelength was studied.
