Preventing Hydrogen Embrittlement: The Role of Barrier Coatings for the Hydrogen Economy

open access: yesHydrogen, 2023
Hydrogen barrier coatings are protective layers consisting of materials with a low intrinsic hydrogen diffusivity and solubility, showing the potential to delay, reduce or hinder hydrogen permeation.

Sex Representation in US Stroke Clinical Trials: A Decade of Trends and Challenges

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Stroke remains a major cause of disability and mortality in the US, with significant sex‐based disparities, and females remain underrepresented in stroke clinical trials. We aimed to examine sex representation in US‐based stroke clinical trials, identify trial characteristics associated with higher female enrollment (≥ 50%), and ...

Choroid Plexus Enlargement and USPIO‐Based Inflammatory Feature in Cerebral Small Vessel Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective The choroid plexus (CP) is a key component of the blood–cerebrospinal fluid barrier (BCSFB), but its mechanism of action in cerebral small vessel disease (CSVD) remains unclear. This study investigated CP volume (CPV) alterations and their association with conventional imaging markers in CSVD and explored the underlying role of ...

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

open access: yesAdvanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Effect of permeation enhancers on the penetration mechanism of transfersomal gel of ketoconazole

open access: yesJournal of Advanced Pharmaceutical Technology & Research, 2012
The aim of the present research work was to investigate the potential of transfersome formulations for transdermal delivery of Ketoconazole (KTZ). KTZ is a broad-spectrum antifungal agent that is active against a wide variety of fungi and yeasts.

Swelling‐Programmed Topographical Guidance for Dynamic Spheroid Self‐Assembly via a Mechanochemical Hydrogel Niche

open access: yesAdvanced Functional Materials, EarlyView.
A swelling‐programmed micropatterned hydrogel guides adherent cells through a controlled transition from cell–matrix anchoring to cadherin‐mediated cell–cell compaction, enabling rapid assembly of high‐viability spheroids with defined size and morphology.

"In silico" prediction of drug transport across physiological barriers [PDF]

open access: yes, 2011
Physiological barriers maintain and safeguard homeostasis of certain body compartments by an increased resistance against free diffusion. Distribution and pharmacokinetics of drugs can be altered as well, if they have to cross these barriers in order to ...

Nanodefect-controlled permeation in AlOx/polymer gas barrier films

open access: yes, 2017
The permeation of water vapour through a coated polymer gas barrier film is controlled by the defects in the coating. By modelling these defects as a combination of macro-defects (in which the activation energy of permeation is that of the underlying ...
