Free-energy profiles along reduction pathways of MoS2 M-edge and S-edge by dihydrogen: a first-principles study

open access: yes, 2011
We present the results of DFT calculations of free energy profiles along the reaction pathways starting from 50% coverage of MoS2 M-edge and 100% coverage of S-edge by sulfur, and leading to 37% coverage, i.e.

Lipids to biojet and sustainable aviation fuel: uses and competing demands for lipid feedstocks

open access: yesBiofuels, Bioproducts and Biorefining, Volume 20, Issue 1, Page 9-19, January/February 2026.
Abstract The use of biojet and sustainable aviation fuels (SAF) as low carbon‐intensity (CI) fuels is likely to be the primary pathway to decarbonize aviation. ‘Waste lipids’, such as fats, oils, and greases (FOGs), are preferred feedstocks due to their lower CI. However, they are mainly used to make biodiesel or renewable diesel.

DEVELOPMENT OF A DISCRETE MATHEMATICAL MODEL OF THE HYDROTREATING DIESEL FUEL REACTOR

open access: yesСовременная наука и инновации, 2022
The article gives an example of the transformation of the initial mathematical model of the hydrotreating diesel fuel reactor which is a system of algebraic equations into its discrete analogue, using the method of "nets" (finite difference method).

Unsupported trimetallic Ni(Co)-Mo-W sulphide catalysts prepared from mixed oxides: characterisation and catalytic tests for simultaneous tetralin HDA and dibenzothiophene HDS reactions [PDF]

open access: yes, 2017
Unsupported A-Mo-W (A = Ni or Co) sulphide catalysts were obtained from mixed oxides containing different W:Mo ratios. An in situ liquid-phase sulphidation of the mixed oxides in a batch reactor was followed by catalytic tests in a liquid-phase reaction (

Cryo Electron Tomography Reveals the Three‐Dimensional Structure of Disordered γ‐Al2O3 in Its Bare, Liquid‐Impregnated, and Freeze‐Dried Status

open access: yesChemistry–Methods, Volume 6, Issue 1, January 2026.
This “dry” cryo‐ET workflow enables 3D visualization of water‐ and metal‐salt solution in a disordered mesoporous γ‐Al2O3 support. Quantification of the bare and liquid‐impregnated γ‐Al2O3 support reveals intrinsic surface and mesopore heterogeneity.
