Inverse magnetic catalysis induced by sphalerons

, 2013
The recently discovered inverse magnetic catalysis around the critical temperature indicates that some important information is missing in our current understanding of conventional chiral dynamics of QCD, which is enhanced by the magnetic field.

Oxidative coupling of methane in a mixed-conducting perovskite membrane reactor [PDF]

, 1995
Ionic-electronic mixed-conducting perovskite-type oxide La0.6Sr0.4Co0.8Fe0.2O3 was applied as a dense membrane for oxygen supply in a reactor for methane coupling.

Highly selective hydrogenation of arenes using nanostructured ruthenium catalysts modified with a carbon–nitrogen matrix

Nature Communications, 2016
The selective reduction of arenes is important in organic synthesis and also valorization of biomass. Here, the authors report the use of ruthenium-based nanoparticles, which display high activity in arene reduction and preferentially hydrogenate ...

Simulation of Steam Reforming Tube with Shaped Particles

Eurasian Chemico-Technological Journal, 2005
Shaped catalysts are widely used in steam reforming. A comprehensive mathematical model able to predict and compare performance of different shaped catalysts is developed.

Magnetic Catalysis in AdS4

, 2012
We study the formation of fermion condensates in Anti de Sitter space. In particular, we describe a novel version of magnetic catalysis that arises for fermions in asymptotically AdS4 geometries which cap off in the infra-red with a hard wall.

Kinetics of catalysis with surface disorder [PDF]

, 1996
We study the effects of generalised surface disorder on the monomer-monomer model of heterogeneous catalysis, where disorder is implemented by allowing different adsorption rates for each lattice site.

Deactivation and Regeneration of Mo/ZSM-5 Catalysts for Methane Dehydroaromatization

Eurasian Chemico-Technological Journal, 2010
The methane dehydroaromatization (DHA) was studied over a series of impregnated Mo/ZSM-5 catalysts with different molybdenum contents (1-10 wt.%). It was shown that total methane conversion was decreased by 30% during 12 h of DHA reaction.

Holographic Monopole Catalysis of Baryon Decay

, 2008
We study how monopole catalysis of baryon decay is realized in holographic QCD. Physics of monopole catalysis becomes much simpler in holographic description as it occurs due to the violation of the Bianchi identity for the 5D gauge symmetry when ...

Influence of feedstock composition on the pressure drop buildup in gas oil hydrotreater

Chimica Techno Acta
In this work two samples of solid particulates obtained from the intergranular space of the guard beds catalyst of industrial gas oil hydrotreating reactors were investigated. The hydrotreating reactors were operated on feedstock of different composition.
