A series of Ru–protein–Co biohybrids have been prepared using the electron transfer proteins ferredoxin (Fd) and flavodoxin (Fld) as scaffolds for photocatalytic hydrogen production. The light-generated charge separation within these hybrids has been monitored by transient optical and electron paramagnetic resonance spectroscopies. Two distinct electron transfer pathways are observed. The Ru–Fd...

Most luminous infrared galaxies (LIGs) are closely interacting/merging systems rich in molecular gas. We study here the relationship between the stage of the galaxy-galaxy interactions, the molecular gas mass, and the star formation rate as deduced from the infrared luminosity LIR in LIGs. We find a correlation between the CO(1-0) luminosity (a measure of molecular mass M(H2)) and the projected...

Ta3N5 is one of the most promising photocatalyst candidates for solar water splitting, but it still remains challenging to achieve overall water splitting via Ta3N5-based photocatalysts regardless of whether it uses a one step or two step method. Here we will address the relatively poor photocatalytic proton reduction of Ta3N5 with an effort for the promotion of charge separation via barium mod...

Clean methanol can play an important role in achieving net zero emission targets by decarbonizing the energy and chemical sectors. Conventionally, is produced using fossil fuel as raw material, which releases a significant amount of greenhouse gases (GHGs) into environment. methanol, hydrogen (H2) from renewable sources (green H2) captured carbon dioxide (CO2), totally free influence fuel. Due ...

Nowadays, we face a series of global challenges, including the growing depletion fossil energy, environmental pollution, and warming. The replacement coal, petroleum, natural gas by secondary energy resources is vital for sustainable development. Hydrogen (H2) considered ultimate in 21st century because its diverse sources, cleanliness, low carbon emission, flexibility, high efficiency. H2 fuel...

The HelixJet, a plasma source operating under atmospheric pressure with RF power, was used for the synthesis of silicon nanoparticles (Si-NPs) in context relevance nanomedicine, sensor technology, and nanotechnology. HelixJet operated variety He/Ar/H2/SiH4 gas mixtures to characterize Si-NPs regard their size, crystallinity, structure, photoluminescence. Distinct varieties nanomaterials size ra...

Work in 2012-2013 focused on studying gas permeability, diffusivity and solubility of polyimides and thermally rearranged (TR) polymers based on 3,3’-dihydroxy-4,4’diaminobiphenyl (HAB) and 2,2’-bis-(3,4-dicarboxyphenyl) hexafluoropropane dianhydride (6FDA). To determine the effect of temperature on gas sorption, we studied H2 sorption in the HAB-6FDA polyimide and 3 partially converted HAB-6FD...
