Impact of Surface Properties of Core Material on the Stability of Hot Melt-Coated Multiparticulate Systems

open access: yesPharmaceutics, 2021
Hot melt coating (HMC) of an active pharmaceutical ingredient (API) powder with lipid-based excipients is an innovative method for manufacturing patient-convenient dosage forms.

Spontaneous wettability patterning via creasing instability [PDF]

open access: yes, 2015
Surfaces with patterned wettability contrast are important in industrial applications such as heat transfer, water collection, and particle separation. Traditional methods of fabricating such surfaces rely on microfabrication technologies, which are only

Impact of Adsorption Layer Properties on Drainage Behavior of Microscopic Foam Films: The Case of Cationic/Nonionic Surfactant Mixtures

open access: yesColloids and Interfaces, 2020
Aqueous mixtures of cationic hexadecyltrimethylammonium chloride (CTAC) and nonionic pentaethyleneglycol monododecyl ether (C12E5) are investigated. Adsorption layer properties are systematically studied within a wide concentration range for a 1:1 molar ...

Thermodynamic and Interfacial Characterization of Petroleum Industry Surfactants: A Study on Critical Micelle Concentration and Interfacial Tension Behavior under Mild Conditions. [PDF]

open access: yesChemistryOpen
The interfacial and thermodynamic properties of five petroleum industry surfactants are evaluated under mild conditions. Interfacial tension is measured using spinning drop tensiometry, and critical micelle concentrations are determined conductometrically.

Elastometry of deflated capsules elastic moduli from shape and wrinkle analysis [PDF]

open access: yes, 2013
Elastic capsules, prepared from droplets or bubbles attached to a capillary (as in a pendant drop tensiometer), can be deflated by suction through the capillary.

Commencement measurements giving fundamental surface tension determinations in tensiometry

open access: yesJournal of Physics: Conference Series, 2011
This study provides experimental testing of a ray-tracing model of the tensiotrace that explores the measurement potential of a well-defined optical position in the tensiotrace signal known as the 'commencement'. This point is defined as the first measureable optical coupling in the fiber drophead between source and collector fibers for light injected ...

A Multistate Adsorption Model for the Adsorption of C14EO4 and C14EO8 at the Solution/Air Interface

open access: yesColloids and Interfaces, 2021
The dynamic and equilibrium properties of adsorption layers of poly (oxyethylene) alkyl ether (CnEOm) can be well described by the reorientation model. In its classical version, it assumes two adsorption states; however, there are obviously surfactants ...

Metabolism and motility in prebiotic structures [PDF]

open access: yes, 2011
Easily accessible, primitive chemical structures produced by self-assembly of hydrophobic substances into oil droplets may result in self-moving agents able to sense their environment and move to avoid equilibrium.

Determination of the Dielectrophoretic Force Induced by the Photovoltaic Effect on Lithium Niobate

open access: yesMicromachines, 2022
The actuation of droplets on a surface is extremely relevant for microfluidic applications. In recent years, various methodologies have been used. A promising solution relies on iron-doped lithium niobate crystals that, when illuminated, generate an ...
