From colloidal dispersions to colloidal pastesthrough solid–liquid separation processes [PDF]

open access: yes, 2005
Solid–liquid separation is an operation that starts with a dispersion of solid particles in a liquid and removes some of the liquid from the particles, producing a concentrated solid paste and a clean liquid phase.

Polar Pore Surface of Polyamide Membranes Enabling Efficient Solvent Mixture Separation

open access: yesAdvanced Functional Materials, EarlyView.
A polyamide membrane with polar pore surfaces and relatively large pore is fabricated through interfacial polymerization between polyethyleneimine and trimesoyl chloride. Rapid separation of solvents with polarity differences is achieved by the synergistic effects of pore polarity and size sieving.

Designing of Self‐Dispersing Soft Dendritic Microcleaners for Microplastics Capture and Recovery

open access: yesAdvanced Functional Materials, EarlyView.
The capture and recovery of microplastics from open aquatic systems is a complex problem, which necessitates nontrivial solutions. The principles of a comprehensive multistage process based on sustainably sourced microcleaners with hierarchical morphology are demonstrated.

Donnan Equilibrium Revisited: Coupling between Ion Concentrations, Osmotic Pressure, and Donnan Potential [PDF]

open access: yesarXiv, 2021
This paper discusses the little-known fact that Donnan's equilibrium criteria established over 100 years ago neglected the coupling between ion concentrations and the osmotic pressure. Such coupling can be treated based on general thermodynamic considerations including the solvent equilibrium, leading to a membrane potential that consists of not only ...

Observations on the physiological development of trout eggs [Translation from: Roux. Arch. f. Entwicklungsmechanik der Organismen, 114. 771, 1929] [PDF]

open access: yes, 1929
The osmotic pressure of the perivitelline fluid and the yolk of trout (Salmo trutta) eggs were measured separately by the Drucker-Schrein method. The permeability of the egg membrane and the variations in the osmotic pressure of the eggs when placed in ...

Stress-structure relation in dense colloidal melt under forward and instantaneous reversal of shear

open access: yes, 2015
Dense supercooled colloidal melt in forward shear from a quiescent state shows overshoot in shear stress at 10% strain with an unchanged fluid structure at equal stress before and after overshoot.

The nature of osmotic pressure [PDF]

open access: yesExperimental Biology and Medicine, 1919
The hemolytic effect of formaldehyde and that of urea, which were first observed by Eisenberg, are found to be, like that of boric acid, the result of osmotic pressure.A comparative, quantitative study of the hemolytic action of these three substances shows that(1) The same degree of osmotic hemolysis is not produced by identical “osmotic ...

“Therapies Through Gut:” Targeted Drug Delivery for Non‐Gastrointestinal Diseases by Oral Administration

open access: yesAdvanced Healthcare Materials, EarlyView.
Schematic illustration of the mechanism of targeted delivery of nanoparticles including 1) paracellular, 2) endolysosomal escape, 3) receptor mediated endocytosis, and 4) M cell mediated transport for non‐GI diseases by oral administration such as atherosclerosis, cancer, diabetes, and brain diseases. Abstract Oral drug delivery is a promising approach

Pontine lesion in hyperglycemic crises: Relevance to osmotic demyelination syndrome and posterior reversible encephalopathy syndrome

open access: yesJournal of Diabetes Investigation, 2023
We herein describe a case of type 1 diabetes that presented with a pontine lesion during two hyperglycemic crises accompanied by marked fluctuations in serum osmotic pressure and blood pressure. Magnetic resonance imaging showed swollen pons with osmotic

Attraction Between Like-Charge Surfaces in Polar Mixtures

open access: yes, 2011
We examine the force between two charged surfaces immersed in aqueous mixtures having a coexistence curve. For a homogeneous water-poor phase, as the distance between the surfaces is decreased, a water-rich phase condenses at a distance $D_t$ in the ...
