Wettability Increase by “Corona” Ionization [PDF]

open access: yesLangmuir, 2011
Experiments showing an increase in the wettability of a hydrophobic surface when using corona air ionization are shown. Photoluminiscence observations support the predictions of charge accumulation at the triple line and confirm previous experiments. In all of the experiments, the contact angle was in the saturation regime at a value smaller than that ...

Effect of Patterned Slip on Micro and Nanofluidic Flows

open access: yes, 2005
We consider the flow of a Newtonian fluid in a nano or microchannel with walls that have patterned variations in slip length. We formulate a set of equations to describe the effects on an incompressible Newtonian flow of small variations in slip, and ...

Surface modification of an Al2O3/SiO2 based ceramic treated with CO2, Nd:YAG, excimer and high power diode lasers for altered wettability characteristics [PDF]

open access: yes, 1998
Interaction of CO2, Nd:YAG, excimer and high power diode laser (HPDL) radiation with the surface of an Al2O3/SiO2 based ceramic was found to affect significant changes in the wettability characteristics of the material.

Effects of Lignosulfonate Structure on the Surface Activity and Wettability to a Hydrophobic Powder

open access: yesBioResources, 2014
The wettability of a solid material is very important in many applications, such as food, agrochemical formulations, and cosmetics. Wettability can be improved by adding surface active agents, especially biocompatible surfactants derived from biomass. In

The effects of high power diode laser radiation on the wettability, adhesion and bonding characteristics of an alumina/silica-based oxide and vitreous enamel [PDF]

open access: yes, 1999
An amalgamated alumina/silica-based oxide compound (AOC) was surface treated using a 60 W high power diode laser (HPDL). The effects of HPDL radiation on the wettability and adhesion characteristics of the AOC and a vitreous enamel have been determined.

On the predominant mechanisms active during the high power diode laser modification of the wettability characteristics of an SiO2/Al2O3-based ceramic material [PDF]

open access: yes, 2002
The mechanisms responsible for modifications to the wettability characteristics of a SiO2/Al2O3-based ceramic material in terms of a test liquid set comprising of human blood, human blood plasma, glycerol and 4-octonol after high power diode laser (HPDL)

Wetting gradient induced separation of emulsions: A combined experimental and lattice Boltzmann computer simulation study

open access: yes, 2008
Guided motion of emulsions is studied via combined experimental and theoretical investigations. The focus of the work is on basic issues related to driving forces generated via a step-wise (abrupt) change in wetting properties of the substrate along a ...

Rock Wettability Alteration Induced by the Injection of Various Fluids: A Review

open access: yesApplied Sciences
Wettability is a key parameter that determines the distribution and behavior of fluids in the porous media of oil reservoirs. Understanding and controlling wettability significantly impacts the effectiveness of various enhanced oil recovery (EOR) methods
