Inorganic and organomodified nano-montmorillonite dispersions for use as supplementary cementitious materials – a novel theory based on nanostructural studies

open access: yesNanocomposites, 2017
The compatibility of three nano-montmorillonite (NMt) dispersions in hydrating cement binders was investigated and a new theory linking the nanostructure of nanoclay dispersions to their effect on the macroscale performance of cement pastes is presented.

Validation of smart nanoparticles as controlled drug delivery systems: loading and pH-dependent release of pilocarpine [PDF]

open access: yes, 2017
Micelles are good devices for use as controlled drug delivery systems because they exhibit the ability to protect the encapsulated substance from the routes of degradation until they reach the site of action. The present work assesses loading kinetics of

Emulsions stabilised by whey protein microgel particles: Towards food-grade Pickering emulsions [PDF]

open access: yes, 2014
We have investigated a new class of food-grade particles, whey protein microgels, as stabilisers of triglyceride-water emulsions. The sub-micron particles stabilized oil-in-water emulsions at all pH with and without salt.

Enhanced dispersibility of graphitic carbon nitride particles in aqueous and organic media via a one-pot grafting approach [PDF]

open access: yes, 2017
A facile route to synthesize hydrophilically or hydrophobically grafted graphitic carbon nitride (g-CN) is reported. For this purpose, functionalized olefinic molecules with a low polymerization tendency are utilized for grafting onto the surface to ...

Preparation of Few-Layer Graphene Dispersions from Hydrothermally Expanded Graphite

open access: yesApplied Sciences, 2019
In this study, we propose a novel approach to prepare few-layer graphene (FLG) dispersions, which is realized by exfoliating natural graphite flakes in a surfactant aqueous solution under hydrothermal treatment and liquid-phase exfoliation.

Preparation and Dispersion Performance of Hydrophobic Fumed Silica Aqueous Dispersion

open access: yesPolymers, 2023
Hydrophobic fumed silica (HFS) is a commonly used rheology additive in waterborne coatings. A series of experiments were conducted on the HFS-dispersing technology in this study. The size and structure of HFS primary particles were observed via transmission electron microscopy (TEM).

Effect of isolation conditions on structural properties and surface behavior of soy-whey proteins [PDF]

open access: yes, 2018
In this study, the impact of isolation conditions on structural and surface properties at the air/water interface of soy-whey proteins (SWP) was assessed. SWP were obtained by precipitation of soy-whey (at pH 4.5 or 8.0) with acetone or ammonium sulfate.
