Methodological Investigation for Hydrogen Addition to Small Cage Carbon Fullerenes

open access: yesCrystals, 2021
Hydrogenated small fullerenes (Cn, n < 60) are of interest as potential astrochemical species, and as intermediates in hydrogen-catalysed fullerene growth.

Effects of hydrogen addition on soot formation in iso-octane pyrolysis behind a reflected shock wave

open access: yesJournal of Thermal Science and Technology, 2016
In the present paper, soot formation process was studied in pyrolysis of iso-octane added hydrogen highly diluted with argon in the temperature range of 1800-2600 K and in the pressure of 1.2 ± 0.1 MPa behind a reflected shock wave. As a test gas, 1% iso-

Theoretical study on interaction of hydrogen with single-walled boron nitride nanotubes. II. Collision, storage, and adsorption [PDF]

open access: yes, 2005
Collision and adsorption of hydrogen with high incident kinetic energies on a single-walled boron nitride (BN) nanotube have been investigated. Molecular-dynamics (MD) simulations indicate that at incident energies below 14 eV hydrogen bounces off the BN

Effect of hydrogen blending on the combustion performance, emission, and cycle-to-cycle variation characteristics of a single-cylinder GDI spark ignition dual-fuel engine

open access: yesInternational Journal of Thermofluids, 2023
The effect of hydrogen addition on combustion, performance, emission and cyclic variation under different hydrogen flow rates (2, 5, 8, 11, and 14 LPM) were investigated based on a SI engine with hydrogen port induction and gasoline direct injection. The

Effect of Zr3Fe addition on hydrogen storage behaviour of Ti2CrV alloys

open access: yesHeliyon, 2023
In this work, the hydrogen storage behavior of Ti2CrV + X wt.% Zr3Fe, where X = 2, 4, 6, 8 and 10 was investigated. The synthesis of all samples was carried out through arc-melting, followed by comprehensive characterization using X-ray diffraction ...
