Modeling the pulsed neutron response for natural hydrogen detection

Frontiers in Earth Science
Hydrogen gas is a promising clean-energy vector that can alleviate the current imbalance between energy supply and demand, diversify the energy portfolio, and underpin the sustainable development of oil and gas resources. This study pinpoints the factors

Determination of Gas Permeation Properties in Polymer Using Capacitive Electrode Sensors

Sensors, 2022
The objective of this work was to develop an effective technique for characterizing the permeation properties of various gases, including H2, He, N2, and Ar, that are absorbed in polymers. Simultaneous three-channel real-time techniques for measuring the

On the nature of hydrogen-rich superluminous supernovae [PDF]

Monthly Notices of the Royal Astronomical Society, 2018
We present two hydrogen-rich superluminous supernovae (SLSNe), namely SN2013hx and PS15br. These objects, together with SN2008es are the only SLSNe showing a distinct, broad Halpha feature during the photospheric phase and also do not show any sign of strong interaction between fast-moving ejecta and circumstellar shells in their early spectra. Despite

Sonoactivated polycrystalline Ni electrodes for alkaline oxygen evolution reaction

Ultrasonics Sonochemistry, 2022
The development of cost-effective and active water-splitting electrocatalysts is an essential step toward the realization of sustainable energy. Its success requires an intensive improvement in the kinetics of the anodic half-reaction of the oxygen ...

Natural H₂ Emanations in the Rio de la Plata Craton, First Data

Geosciences
This study presents the first comprehensive soil gas survey across southern Uruguay’s H2 prospective terranes. A pre-field trip selection was done on the basement rock nature, as well as vegetation anomalies in subcircular depressions and fault presence.

Origin, discovery, exploration and development status and prospect of global natural hydrogen under the background of “carbon neutrality”

China Geology, 2022
Global energy structure is experiencing the third transition from fossil energy to non-fossil energy, to solve future energy problems, cope with climate change, and achieve net-zero emissions targets by 2050.

Vaux-en-Bugey (Ain, France): the first gas field produced in France, providing learning lessons for natural hydrogen in the sub-surface?

BSGF - Earth Sciences Bulletin, 2020
The former Vaux-en-Bugey field, first French methane production from early 20th century, is revisited as a case study to address the present generation and accumulation theories for gases like hydrogen and helium.

Phosphoinositides and inositol phosphates as molecular glues

FEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Water budget in flat vs. steep subduction: implication for volcanism and potential for H2 production

BSGF - Earth Sciences Bulletin
In this study, we model the processes of (de)hydration and melting within subduction zones using a thermo-mechanical modeling approach. Multiple 2D simulations are conducted to investigate how the subduction angle influences the water budget in oceanic ...
