Magnetic catalysis and inverse catalysis for heavy pions [PDF]

open access: yesJournal of High Energy Physics, 2019
Abstract We investigate the QCD phase diagram for nonzero background magnetic fields using first-principles lattice simulations. At the physical point (in terms of quark masses), the thermodynamics of this system is controlled by two opposing effects: magnetic catalysis (enhancement of the quark condensate) at low temperature and ...

High-entropy intermetallics on ceria as efficient catalysts for the oxidative dehydrogenation of propane using CO2

open access: yesNature Communications, 2022
The oxidative dehydrogenation of propane using CO2 is a promising technique for high-yield propylene production and CO2 utilization. Here the authors report a unique catalyst material and design concept based on high-entropy intermetallics for this ...

Reversible catalysis [PDF]

open access: yesNature Reviews Chemistry, 2021
We describe as 'reversible' a bidirectional catalyst that allows a reaction to proceed at a significant rate in response to even a small departure from equilibrium, resulting in fast and energy-efficient chemical transformation. Examining the relation between reaction rate and thermodynamic driving force is the basis of electrochemical investigations ...

Psychrophily and Catalysis [PDF]

open access: yesBiology, 2013
Polar and other low temperature environments are characterized by a low content in energy and this factor has a strong incidence on living organisms which populate these rather common habitats. Indeed, low temperatures have a negative effect on ectothermic populations since they can affect their growth, reaction rates of biochemical reactions, membrane

Investigation of the possibility to combine bulk and supported catalysts to increase the efficiency of hydrotreating process

open access: yesChimica Techno Acta
Hydrotreating catalysts are of great interest for researchers in oil refining. Nowadays, bulk NiMoW catalysts attract significant attention due to much higher activity in target hydrotreating reactions.

Single-Atom Alloy Catalysis.

open access: yesChemical Reviews, 2020
Single-atom alloys (SAAs) play an increasingly significant role in the field of single-site catalysis and are typically composed of catalytically active elements atomically dispersed in more inert and catalytically selective host metals.

Comparison of the HDS DBT reaction using bulk and supported catalysts

open access: yesChimica Techno Acta
The paper describes in detail the procedure for the preparation of a granular bulk NiMoW catalyst and a supported reference NiMo/Al2O3 catalyst. Mention is made of investigations of the supported and bulk catalysts by various physico-chemical methods ...
