2030 Ambitions for Hydrogen, Clean Hydrogen, and Green Hydrogen

ASEC 2023, 2023
Hydrogen production has been dominated by gray hydrogen (hydrogen produced from fossil fuels without carbon capture). Historical data for 2019–2021 show nearly steady global production of and demand for hydrogen, with an annual average of 92 Mt (million tonnes) for each.

Relativistic and retardation effects in the two--photon ionization of hydrogen--like ions

, 2003
The non-resonant two-photon ionization of hydrogen-like ions is studied in second-order perturbation theory, based on the Dirac equation. To carry out the summation over the complete Coulomb spectrum, a Green function approach has been applied to the ...

The mean free path of hydrogen ionizing photons during the epoch of reionization [PDF]

, 2017
We use the Aurora radiation-hydrodynamical simulations to study the mean free path (MFP) for hydrogen ionizing photons during the epoch of reionization. We directly measure the MFP by averaging the distance 1 Ry photons travel before reaching an optical ...

Exploiting metabolic adaptations to overcome dabrafenib treatment resistance in melanoma cells

Molecular Oncology, EarlyView.
We show that dabrafenib‐resistant melanoma cells undergo mitochondrial remodeling, leading to elevated respiration and ROS production balanced by stronger antioxidant defenses. This altered redox state promotes survival despite mitochondrial damage but renders resistant cells highly vulnerable to ROS‐inducing compounds such as PEITC, highlighting redox

Urea electrooxidation coupled with energy-saving H2 production using bimetallic sulfide heterojunctions

Electrochemistry Communications
The theoretical electrocatalytic potential for the urea oxidation reaction (UOR) is notably low at 0.37 V, positioning it as a promising alternative to hydrogen evolution reaction for traditional water electrolysis.

A study on a political system for the advance in green hydrogen technology: a South Korea case study

Energy, Sustainability and Society, 2023
Background Hydrogen energy, a type of renewable energy if produced without fossil fuel, has a critical issue in that most of it is still produced from carbon footprint heavy industries such as the fossil fuel industry.

Role of Hydrogen Bonding in Green Fluorescent Protein-like Chromophore Emission. [PDF]

, 2019
The fluorescence emission from green fluorescent protein (GFP) is known to be heavily influenced by hydrogen bonding between the core fluorophore and the surrounding side chains or water molecules.

Cell surface interactome analysis identifies TSPAN4 as a negative regulator of PD‐L1 in melanoma

Molecular Oncology, EarlyView.
Using cell surface proximity biotinylation, we identified tetraspanin TSPAN4 within the PD‐L1 interactome of melanoma cells. TSPAN4 negatively regulates PD‐L1 expression and lateral mobility by limiting its interaction with CMTM6 and promoting PD‐L1 degradation.
