Effective interaction between a colloid and a soft interface near criticality [PDF]

open access: green, 2014
Within mean-field theory we determine the universal scaling function for the effective force acting on a single colloid located near the interface between two coexisting liquid phases of a binary liquid mixture close to its critical consolute point. This

Ionic and non-ionic surfactants: Micelles, reverse micelles and micro heterogenous systems

open access: yesPubvet, 2022
Surfactants are surface-active agents which belong to the category of amphiphilic molecules. Indeed, surfactants are characterized for the presence of polar and apolar domains in the same compound.

Temperature and Concentration Dependence of Human Whole Blood and Protein Drying Droplets

open access: yesBiomolecules, 2021
The drying of bio-colloidal droplets can be used in many medical and forensic applications. The whole human blood is the most complex bio-colloid system, whereas bovine serum albumin (BSA) is the simplest. This paper focuses on the drying characteristics

Fluid Therapy in Pulmonary Disease: How Careful Do We Need to Be?

open access: yesFrontiers in Veterinary Science, 2021
Intravenous fluid therapy is a vital and life-saving therapeutic in veterinary medicine. In the absence of heart or lung disease, trauma or sepsis there is limited evidence that fluid therapy will have a detrimental effect on lung function.

Active nematic multipoles: Flow responses and the dynamics of defects and colloids

open access: yesFrontiers in Physics, 2023
We introduce a general description of localised distortions in active nematics using the framework of active nematic multipoles. We give the Stokesian flows for arbitrary multipoles in terms of differentiation of a fundamental flow response and describe ...

Permselectivity of the glomerular wall examined with iron compound tracer [PDF]

open access: yes, 1977
Rat kidney endothelial cell morphology was examined after introducing iron colloid particles of positive or negative charge to investigate the relationship between the electric charge and permeation through the glomerular capillary.

Nucleation and growth of sodium colloids in NaCl under irradiation: theory and experiment [PDF]

open access: yes, 2005
A mechanism of radiation-induced emission of Schottky defects from extended defects proposed originally for metals has recently been applied to ionic crystals, where it is based on interactions of excitons with extended defects such as dislocations and ...
