Self-organized enhancement of conductivity in biological ion channels [PDF]

, 2013
We discuss an example of self-organization in a biological system. It arises from long-range ion–ion interactions, and it leads us to propose a new kind of enhanced conduction in ion channels.

Microstructure change and deuterium permeation behavior of ceramic-metal multi-layer coatings after immersion in liquid lithium-lead alloy

Nuclear Materials and Energy, 2018
For the establishment of liquid tritium breeding concepts, static lithium-lead corrosion tests for single-layer erbium oxide coatings and erbium oxide-metal multi-layer coatings were carried out, followed by deuterium permeation measurements.

Characterization of reactively sputtered permeation barrier materials on polymer substrates

, 2022
S.S141-S144Transparent permeation barrier layers are not only used for food packaging but are also needed to encapsulate flexible electronic devices. Magnetron sputtering allows the deposition of high quality oxide barrier layers with a low water vapor ...

Improved In Vitro Model for Intranasal Mucosal Drug Delivery: Primary Olfactory and Respiratory Epithelial Cells Compared with the Permanent Nasal Cell Line RPMI 2650

Pharmaceutics, 2019
Background: The epithelial layer of the nasal mucosa is the first barrier for drug permeation during intranasal drug delivery. With increasing interest for intranasal pathways, adequate in vitro models are required.

Permeation Enhancers for Enhanced Topical Delivery of Pharmaceutical and Cosmeceutical Products

Journal of Dermatology and Dermatologic Surgery
Background: Topical cosmetic and therapeutic agents are often limited in their effectiveness due to the skin barrier, which hinders the permeation of active ingredients.

Further Development of Surface Metrology Methods for Predicting the Functional Performance of Flexible PV Barrier Films

, 2013
Surface topography analysis plays a very significant role in determining the functional performance for many engineering surfaces. In this paper, feature characterisation techniques, based on the ‘Wolf pruning’ method are implemented to characterise ...

"In vitro" evaluation of blood-brain barrier transport [PDF]

, 2014
The blood-brain barrier (BBB), which is formed by brain capillary endothelial cells, effectively protects the central nervous system (CNS) from potential neurotoxic agents and maintains the brain homeostasis for synaptic signaling (Abbott, 2004 ...
