Publication – Transparency-changing elastomers by controlling
of the refractive index of liquid inclusions
Complex materials that change their optical properties in response to changes in environmental
conditions can find applications in displays, smart windows, and optical sensors. Here a class of
biphasic composites with stimuli-adaptive optical transmittance is introduced. The biphasic
composites comprise aqueous droplets (a mixture of water, glycerol, and surfactant) embedded
in an elastomeric matrix…

Publication – Transition of Liquid Drops on Microstructured HygrophobicSurfaces from the Impaled Wenzel State to the “Fakir”Cassie−Baxter State
Low adhesion of liquids on solid surfaces can be achieved with protrusions thatminimize the contact area between the liquid and the solid. The wetting state where an aircushion forms under the drop is known as the Cassie−Baxter state. Surfaces where liquids formmacroscopic contact angles above 150° are called superhydrophobic and superhygrophobic, ifwe refer to water or any liquid, respectively. The Cassie state is desirable for applications, but it isusually unstable compared to the Wenzel state, where the drop is in direct contact with therough surface…

Publication – Numerical and experimental investigation of chaotic advection and diffusion mixing effects in 3D multihelical microfluidics for liposome synthesis
The recent advances in nanomaterials’ production by microfluidics with high throughput became critical for industry-scale production. Numerical simulation has been part of this development, allowing faster and more detailed study of the process that would be costly only experimentally…

PICKFOOD participants attending the Food Colloids Conference, in Thessaloniki, Greece
Several PICKFOOD participants attended the 19th Food Colloids Conference, in Thessaloniki, Greece on 14–18 April, 2024
Cellulose Microfibre and potato protein in a double network, gel structure
An animation and a still image of Cellulose Microfibre and potato protein in a double network, gel structure. The protein is depicted in red, and the fibre is depicted in cyan.
Ieuan Roberts-Harry, a Marie Curie PhD Research Scientist at the Unilever Foods Innovation Centre in the Netherlands, will be presenting a poster of this gel structure at the Food Colloids 2024 conference in Thessaloniki in Greece. The topic is Double gels made of interpenetrating networks.
Publication – Pea protein [Pisum sativum] as stabilizer for oil/water emulsions
A map of stability for various water/oil/pea protein compositions has been plotted from the numerous reported results. Two clear regions of stability were identified. High internal oil phase emulsions with 70–80%, v/v oil content stabilized by total pea protein concentration <2.5%, w/v showed stability…

Publication – Influence of Nozzle Geometry and Scale-Up on Oil Droplet Breakup in the Atomization Step during Spray Drying of Emulsions
Spray drying of oil-in-water emulsions is a widespread encapsulation technique. The oil droplet size (ODS) significantly impacts encapsulation efficiency and other powder properties. The ODS is commonly set to a specific value during homogenization, assuming that it remains unchanged throughout the process, which is often inaccurate. This study investigated the impact of atomizer geometry and nozzle dimensions on oil droplet breakup during atomization using pressure-swirl atomizers…

Publication – Naphthyl end-capped bithiophene film on plant-based polyamide-4,10
We report on a vacuum deposited 5,5’-bis(naphth-2-yl)-2,2’-bithiophene (NaT2) film on bio-based polyamide-4,10 (PA410) substrate. The substrate is moderately hydrophobic with dominant dispersive interactions…
