Structure and weak hydrogen bonds in liquid acetaldehyde
(2004-08-30)
Monte Carlo simulations have been performed to investigate the structure and hydrogen bonds formation in liquid acetaldehyde. An all atom model for the acetaldehyde have been optimized in the present work. Theoretical ...

Lichen metabolites modulate hydrogen peroxide and nitric oxide in mouse macrophages
(2009-11-20)
The activities of perlatolic acid (1), atranorin (2), and lecanoric acid (3) and their derivatives, such as orsellinates and β-methyl orsellinates obtained by alcoholysis, were assessed for stimulation of the release of ...
Hydrogen oxidation on ordered intermetallic phases of platinum and tin - A combined experimental and theoretical study
(2013-03-15)
Hydrogen oxidation on the surfaces of the intermetallic compounds Pt 3Sn, PtSn and PtSn2 has been studied by the rotating disc electrode technique. Pt3Sn and PtSn were found to be good catalysts, about as good as Pt, while ...
Changes on iron electrode surface during hydrogen permeation in borate buffer solution
(Pergamon-Elsevier B.V. Ltd, 2008-04-01)
Hydrogen interaction with oxide films grown on iron electrodes at open circuit potential (E-oc) and in the passive region (+0.30 V-ECS) was studied by chronopotentiometry, chronoamperometry and electrochemical impedance ...
A comparative study of hydrogen-induced crackingresistances of API 5L B and X52MS carbon steels
(2019-01-01)
Susceptibility to hydrogen-induced cracking of API 5L B and X52MS low-carbon steels inNACE 177-A, 177-B and 284-B solutions has been investigated by the present work. A met-allographic analysis of these steels was performed ...
The role of the titania and silica supports in Ru-Fe catalysts to partial hydrogenation of benzene
(Elsevier Science BvAmsterdamHolanda, 2003)
Quantum confinement in hydrogen bond
(Wiley-Blackwell, 2015-06-15)
In this work, the quantum confinement effect is proposed as the cause of the displacement of the vibrational spectrum of molecular groups that involve hydrogen bonds. In this approach, the hydrogen bond imposes a space ...
Niobium hydrogenation process Effect of temperature and cooling rate from the hydrogenation temperature
(ELSEVIER SCI LTD, 2011)
High-purity niobium powder can be produced via the hydrogenation and dehydrogenation processes The present work aimed at the effect of temperature and cooling rate conditions on the niobium hydrogenation process using ...
