Evaluation of hydrogen retention behavior in tungsten exposed to hydrogen plasma in QUEST
The W (tungsten) samples were placed at Top, Equator and Bottom plasma facing walls of QUEST (Q-shu University Experiment with Steady-State-Spherical Tokamak) device and exposed to 754 shots of hydrogen plasma during 2017A/W (Autumn/Winter) campaign ...

Laser heating of scanning probe tips for thermal near-field spectroscopy and imaging
Spectroscopy and microscopy of the thermal near-field yield valuable insight into the mechanisms of resonant near-field heat transfer and Casimir and Casimir-Polder forces, as well as providing nanoscale spatial resolution for infrared vibrational ...

Hydration-Induced Local Molecular Structures in Nano-Layered Clay Particles [PDF]
Positronium (Ps) annihilation spectroscopy and thermogravimetry and differential thermal analysis (TG-DTA) were conducted for synthetic smectite clay minerals to investigate local molecular structures induced by water adsorption and desorption.

Microwave radiation influence on the thermal and spectroscopic properties of Na-birnessite-type material [PDF]
The aim of this work was to study the effect of the microwave radiation on the thermal and spectroscopic features, as well as about arrangement (order-disorder) and morphological properties, of the layered manganese oxide with birnessite-type structure ...

In-situ water signal calibration method for thermal desorption spectroscopy
A method is presented that allows to quantify water desorption in a thermal desorption spectroscopy (TDS) setup in-situ. It is based on deuterium (D) desorption from D-containing tungsten covered with a thin, electro-chemically grown tungsten oxide layer.

We present a reaction–diffusion model of hydrogen (H) trapping and release from a metal containing an array of cavities. The model is based on a kinetic description of H trapping in chemisorption sites at the cavity surface and H2 gas precipitation in ...

Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films
Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...
