Electroless nickel-phosphorus amorphous alloy coating as effective barrier for hydrogen permeation and corrosion protection

Journal of Materials Research and Technology
This study focuses on the electroless nickel-phosphorus amorphous coating and its performance as an effective barrier against hydrogen permeation and corrosion. The coating was deposited on 16Mn substrate using the electroless plating technique.

Hydrophobic gating in bundle-crossing ion channels: a case study of TRPV4

Communications Biology, 2023
Transmembrane ion channels frequently regulate ion permeation by forming bundle crossing of the pore-lining helices when deactivated. The resulting physical constriction is believed to serve as the de facto gate that imposes the major free energy barrier

Stochastic dynamics of remote knock-on permeation in biological ion channels [PDF]

, 2013
Brownian dynamics simulations provide evidence for a remote knock-on mechanism facilitating the permeation of a biological ion channel by an ion that is initially trapped at the selectivity filter (SF).

An in vitro Model for Blood Brain Barrier Permeation [PDF]

Scientia Pharmaceutica, 2002
The ability to permeate accross the blood brain barrier (BBB) is essential for drugs acting on the central nervous system (CNS). Thus, systems that allow rapid and inexpensive screening of the BBB-permeability properties of novel lead compounds are of great importance for speeding up the drug discovery process in the CNS-area.

Hydrogen permeation barriers: Basic requirements, materials selection, deposition methods, and quality evaluation

Nuclear Materials and Energy, 2019
An effective permeation reduction of gaseous hydrogen isotopes into a metal wall by introducing a barrier is essential in two main fields: prevention of hydrogen-embrittlement in steels and control of the tritium inventory in future nuclear fusion ...

The Cell-Penetrating Peptide Tat Facilitates Effective Internalization of PSD-95 Inhibitors Into Blood–Brain Barrier Endothelial Cells but less Efficient Permeation Across the Blood–Brain Barrier In Vitro and In Vivo

Frontiers in Drug Delivery, 2022
Inhibition of the interaction between the scaffolding protein PSD-95 and the NMDA receptor has been shown to obstruct ischemic stroke-triggered excitotoxic reactions, leading to neuronal death.

Modelling the effect of mixture components on permeation through skin [PDF]

, 2010
A vehicle influences the concentration of penetrant within the membrane, affecting its diffusivity in the skin and rate of transport. Despite the huge amount of effort made for the understanding and modelling of the skin absorption of chemicals, a ...

Hydrogen Permeation in Fusion Materials and the Development of Tritium Permeation Barriers

Plasma and Fusion Research, 2020
Fuel retention and hydrogen permeation in the first wall of future fusion devices are crucial factors. Due to safety issues and in order to guarantee an economical reactor operation, tritium accumulation into reactor walls and permeation through walls have to be estimated and prevented.

Effect of high hydrostatic pressure on the barrier properties of polyamide-6 films

Brazilian Journal of Medical and Biological Research, 2005
Little is known about the barrier properties of polymer films during high pressure processing of prepackaged foods. In order to learn more about this, we examined the influence of high hydrostatic pressure on the permeation of raspberry ketone (dissolved
