Polymer-Surfactant Mono and Bilayers Monocouches et bicouches de polymères et de tensioactifs

open access: yesOil & Gas Science and Technology, 2006
Although there are many studies of association of polymers and surfactants in solution, much less is known about their association at surfaces. In this paper, several examples will be presented : water insoluble polymers spread at the surface of ...

Use of the corrected plane wave model for the determination of the reflection coefficient during horizontal plate swell interaction [PDF]

open access: yesMATEC Web of Conferences, 2019
The main objective of this work, is to calculate variations of the reflection coefficient of the regular wave by a submerged horizontal plate, using the corrected plane wave model, by choosing appropriately the immersion and the relative length of the ...

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Shear Flow and Large Amplitude Oscillation Shear Study of Solutions of Aggregating Micellar Casein Particles

open access: yesApplied Rheology, 2008
Small micellar casein particles were formed in aqueous solutions of native casein after addition of polyphosphate. These so-called submicelles aggregated and gelled with a rate that increased with increasing temperature.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...
