Initial growth phase of W-fuzz formation in ultra-long pulse helium discharge in LHD

Nuclear Materials and Energy, 2017
In order to confirm the formation of a tungsten fiberform nanostructure (W-fuzz) by helium plasma exposure in the large-sized plasma confinement device, the bulk tungsten with the size of 80 × 20 × 1.5 mm3 was inserted into the divertor leg position in ...

Deuterium retention in tungsten and tungsten alloys exposed to pure and impurities seeding deuterium plasma

Nuclear Materials and Energy, 2020
Polycrystalline tungsten (W) and four kinds of tungsten alloys were exposed to pure and impurities seeding deuterium (D) plasma to investigate the deuterium retention behaviour. The results show that D retention in W increases with the increasing fluence

Supernova Type Ia progenitors from merging double white dwarfs: Using a new population synthesis model [PDF]

, 2012
The study of Type Ia supernovae (SNIa) has lead to greatly improved insights into many fields in astrophysics, however a theoretical explanation of the origin of these events is still lacking.

Effect of surface quality on hydrogen/helium irradiation behavior in tungsten

Nuclear Engineering and Technology, 2022
As the plasma facing material in the nuclear fusion reactor, tungsten has to bear the irradiation impact of high energy particles. The surface quality of tungsten may affect its irradiation resistance, and even affect the service life of fusion reactor ...

Carbon Shell or Core Ignitions in White Dwarfs Accreting from Helium Stars

, 2016
White dwarfs accreting from helium stars can stably burn at the accreted rate and avoid the challenge of mass loss associated with unstable Helium burning that is a concern for many Type Ia supernovae scenarios.

Detection of adulterated drugs in traditional Chinese medicine and dietary supplements using hydrogen as a carrier gas. [PDF]

PLoS ONE, 2018
Helium, a minor component of natural gas and radioactive minerals, is most commonly used as a carrier in gas chromatography-mass spectrometry (GC-MS). Its scarcity leads to limited availability and higher costs.

Quantitative characterization of helium in the ITER-like co-deposition layer by laser-induced breakdown spectroscopy

Nuclear Materials and Energy, 2023
As a product of the D-T burning plasma in tokamak fusion reactors, helium (He) ash would be retained in plasma-facing components like the first wall and divertor, harming the stable operation of burning plasma. The quantitative monitoring of He retention

Comparative study of surface modification and D retention between beryllium and beryllides under high flux plasma exposure

Nuclear Materials and Energy, 2021
The microstructures and deuterium (D) retention properties were investigated for beryllium intermetallic compounds (beryllides), such as Be12Ti and Be12V, compared to pure beryllium (Be), exposed to high density pure D and helium (He) mixed plasmas.

Influence of extraction methods on the composition of essential oils of Achillea millefolium L. from Lithuania [PDF]

, 2014
In this study, flowering aerial parts of Achillea millefolium were used as a matrix for supercritical CO2 extraction (SFE) of volatile oil. The collected extracts were analyzed by GC-FID and GC-MS methods and their composition were compared with that of ...
