Insights into the hydrogen dissociation mechanism on lithium edge-decorated carbon rings and graphene nanoribbon
(Elsevier, 2016)
The purpose of this study is to show that H-2 is easily dissociated on lithium edge decorated carbon systems to form strong C-H and Li-H bonds. This mechanism has not been considered in previous studies where these kinds ...
Catalytic hydrogenation of N-benzylideneaniline using a new complex of ruthenium(II) derived from 2-ferrocenyl-1,8-naphthyridine

2-Ferrocenyl-1,8-naphthyridine (1) and cis,cis,cis-dicarbonyl-dichloro-bis (2-ferrocenyl-1,8-naphthyridine) ruthenium(II) complex (2) have been synthesized and characterized by IR, 1H-NMR spectroscopy and elemental analysis. ...
Ultracytochemical localization of hydrogen peroxide production by dental plaque bacteria
(1998)
This study looked for evidence of in vitro hydrogen peroxide (HP) synthesis in human dental plaque, using an ultracytochemical technique that included incubation in a CeCl3-rich medium. Supragingival dental plaque was ...

The structure of the complex (PHL)2S. HN(C6H5)2 has been determined by single-crystal X-ray diffraction methods. The compound crystallizes in the triclinic system, space group P 1, with unit cell dimensions a = 896. 1, b ...
Co2SnO4/Carbon nanotubes composites: A novel approach for electrochemical sensing of Hydrogen Peroxide
(Wiley-V C H Verlag GMBH, 2018)
For the first time Co2SnO4 (CTO)/Carbon nanotubes (CNT) composites were prepared and used to modify glassy carbon electrodes for the amperometric determination of hydrogen peroxide. The catalytic activity of composites ...
Hydrogenation of N-benzylideneaniline by palladium (II) catalysts with phosphorus-nitrogen ligands using formic acid as a renewable hydrogen source
(Elsevier B.V., 2019)
This paper reports the hydrogenation of N-benzylideneaniline catalysed by Pd(II) compounds containing heterobidentated phosphorus-nitrogen (PN) ligands. The general formulas of the catalysts are cis-[PdCl2(L1)] and ...
Hydrogen bonds and heat diffusion in α‑helices: a computational study
(American Chemical Society, 2014)
Recent evidence has shown a correlation between the heat
diffusion pathways and the known allosteric communication pathways in
proteins. Allosteric communication in proteins is a central, yet unsolved,
problem in ...
