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.

FEBS Letters, EarlyView.An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Hydrogenation of Aromatic Nitrocompounds on Supported Mono- and Bimetallic Catalysts
Eurasian Chemico-Technological Journal, 2000 Catalytic hydrogenation of substituted aromatic nitrocompounds and hydrocarbons has been studied. It was established that monometallic Pd-catalysts were suitable for reduction of nitrogroups.

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 ...

Study of Solvent and Catalyst in Diimide Biphasic Hydrogenation System of Natural Rubber
International Journal of TechnologyIn Indonesia, solid rubber is the most common form of natural rubber (NR) intermediates because it is easy to store and transport. However, hydrogenation, a process aimed at improving the quality of NR by addressing its vulnerability to environmental ...

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 ...

Mechanism of Semi-Hydrogenation of Trace Acetylene in Ethylene by [MB12Hx]2-
Taiyuan Ligong Daxue xuebao[Purposes] The main problem of semi-hydrogenation of trace acetylene in ethylene is excessive hydrogenation. High concentration of ethylene is the main cause of excessive hydrogenation, so it is important to design a catalyst with acetylene enrichment ...
