Small fuel cell system with cartridges for controlled hydrogen generation [PDF]
, 2022 S.5340-5345Galvanic cells are investigated which can be used as a hydrogen source for small fuel cell systems. Hydrogen is produced by the reaction of zinc and water in a cell which consist of zinc powder as negative electrode and a hydrogen evolution ...

FEBS Letters, EarlyView.Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

PetroleumIn-situ combustion gasification (ISCG) is a technology in the field pilot stage used for hydrogen generation from oil reservoirs. ISCG is implemented by injecting an oxidant (pure oxygen, air, …) into the reservoir to trigger in-situ chemical reactions ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Silicon as an intermediary between renewable energy and hydrogen [PDF]
, 2004 Weltweit nehmen Kohle-, Öl- und Erdgasvorräte ab, der Energiebedarf dagegen steigt dramatisch an. Regenerative Energien mindern zwar die steigenden Klimagefahren, können aber unseren zukünftigen Energiebedarf in Ballungszentren kaum decken.

Molecular Oncology, EarlyView.Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...
