A Conceptual Approach to Reduce the Product Gas Crossover in Alkaline Electrolyzers

Membranes
The crossover of the product gases hydrogen and oxygen in alkaline electrolyzer operation is a critical factor, severely limiting the operational window in terms of current density and pressure.

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Green hydrogen as a fuel

, 2022
Keys for its contribution to a decarbonised economy Hydrogen produced using renewable energies is expected to play an essential role in the energy transition towards a decarbonised economy by 2050. Although its current main use is as a raw material in industry, hydrogen is a highly versatile fuel, which opens the door to a wide range of new ...

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.

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Effects of a perpendicular ultrasonic field on planar and porous electrodes for hydrogen production in alkaline conditions

Ultrasonics Sonochemistry
Among water electrolysis systems, alkaline water electrolysers (AWE) are promising for large-scale hydrogen production due to their cost-effective nickel (Ni) electrodes.

Green Energy or Green Colonialism? The Case of Green Hydrogen in Namibia

Green hydrogen, promoted by institutions like the International Renewable Energy Agency and the European Union as pivotal to decarbonization, faces criticism through the lens of green colonialism. This paper argues that the energy transition often replicates neo-colonial resource extraction, particularly in Global South nations such as Namibia, where ...

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

FEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

Malformin A1–mediated cytotoxicity in ovarian cancer cells occurs through pyroptosis and autophagy

FEBS Open Bio, EarlyView.
This study investigated the effects of the natural compound Malformin A1 (MA1) on the cytoskeleton that regulates cell proliferation and migration. Disruption of the cytoskeleton can impair these processes and promote cancer cell death. MA1 disrupted cytoskeletal organization, induced DNA damage, inflammation, activated autophagy, and pyroptosis ...
