Interfacial tension and hydrogen-ion concentration [PDF]

Proceedings of the Royal Society of London. Series B, Containing Papers of a Biological Character, 1931
(1) Long chain carboxylic acids dissolved in benzene show regular changes in interfacial tension against aqueous "buffered" solutions as the hydrion concentration of these is altered. A fall in interfacial tension starts at p h 5·5 and extends over the range of 4·0 p h

Ultrasonic Atomization Spray Coating of PCL on an Mg‐Based Alloy Enhanced by Plasma Electrolytic Oxidation for Improved Adhesion, Corrosion Resistance, and Biocompatibility

Advanced Engineering Materials, EarlyView.
Plasma electrolytic oxidation is combined with ultrasonic spray deposition of polycaprolactone (PCL) on WE43 magnesium alloy to improve adhesion, corrosion resistance, and cytocompatibility. The hybrid coating demonstrates significantly reduced hydrogen evolution and enhances mechanical bonding, offering a promising strategy for next‐generation ...

Twenty-four-hour pH monitoring of gastric conduit in post-esophagectomy patients: correlation with clinical and endoscopic parameters in a prospective cohort study from India

Journal of Minimally Invasive Surgery
Purpose: Esophagectomy for malignancy leads to decreased gastric conduit acidity due to bilateral vagotomy and fundic gland area reduction. However, reflux symptoms occur.

3D‐Printable Near‐Infrared‐Responsive Microscale Cantilever made of the Composite Consisting of Ceramic Particles and Graphene Flakes

Advanced Engineering Materials, EarlyView.
A near infrared‐responsive microscale cantilever is developed using a 3D‐printable composite based on photocurable resin consisting of sepiolite and graphene flakes. The material absorbs 1064 nm light, causing shape transformation with an average displacement of 1.3 mm in 1.7 s. Displacement is measured via video recording.

Net lithium deposition and dominant self-sputtering in lithium tokamak experiment-β with a liquid lithium wall

Nuclear Materials and Energy
We observed enhanced net lithium deposition and lithium erosion, possibly dominated by physical sputtering of lithium by lithium-ion bombardment, on the outer plasma-facing surface in the Lithium Tokamak eXperiment-β (LTX-β) during liquid lithium wall ...

LiVO3/LiZnVO4 Nanocomposite: High Performance Electrocatalyst for Ambient Nitrogen Reduction to Ammonia

Advanced Engineering Materials, EarlyView.
Lithium‐mediated electrocatalysis enables sustainable N2 fixation but hindered by parasitic Li deposition. An oxide‐oxide nanocomposite (LiVO3/LiZnVO4) structurally integrates lithium into active sites, suppressing plating and enhancing N2 activation and HER supression.
