A versatile setup for hydrogen isotope permeation studies

Review of Scientific Instruments
The Testbed for Analysis of Permeation of Atoms in Samples (TAPAS) is an experimental setup for ion-driven permeation studies with a focus on investigating wall materials for nuclear fusion devices. A monoenergetic, mass-filtered high-intensity keV ion beam is focused and directed onto the permeation sample by electrostatic ion optics and decelerated ...

Gas phase hydrogen permeation in palladium-25%Ag

, 2005
The results have shown an unexpected through-thickness texture gradient in the as-received Pd alloy. With the exception of a minor stabilization effect for one specific texture component, gas phase hydrogen permeation for up to 48 hours at 350°C has no ...

Structural and Compositional Effects on the Scintillation Properties of Fast Emitting Metal‐Organic Frameworks

Advanced Science, EarlyView.
The crystalline structure, the atomic numbers of the constituent elementsand the size of MOF crystals each influence their photoluminescence and scintillation properties in distinct ways. Together, these factors provide valuable guidelines for designing systems with optimized performance and tunable timing characteristics, arising from the synergistic ...

Hydrogen permeation through a slab sample in the case of high hydrogen concentration

, 2006
Hydrogen trapping sites have a great influence on the hydrogen permeation through a slab sample. The diffusion of the hydrogen in a crystal is generally governed by a parabolic partial differential equation: a numerical simulation code, realized for the ...

Autonomous and Continuous Atmospheric Water Harvesting Using Modified Wood

Advanced Science, EarlyView.
A rigid, hydroxyl‐rich wood skeleton with graded channels is used as a multifunctional host to co‐incorporate a PNipam/PAA network and LiCl, creating a high‐performance sorbent for atmospheric water harvesting. The composite achieves rapid sorption, efficient low‐temperature desorption, and stable cycling, enabling a solar‐powered device with a high ...

Adhesion‐Driven Removal of Microplastics From Aquatic Systems by Using Microgel Glues

Advanced Science, EarlyView.
Soft polymeric microgels function as “glues” that aggregate diverse microplastics through multivalent adhesion, promoting their interfacial deposition and co‐precipitation for efficient removal from water. Remarkably, this approach remains effective even for nanoscale plastic particles as small as 50 nm.
