Mirror symmetry breaking with limited enantioselective autocatalysis and temperature gradients: a stability survey

, 2012
We analyze limited enantioselective (LES) autocatalysis in a temperature gradient and with internal flow/recycling of hot and cold material. Microreversibility forbids broken mirror symmetry for LES in the presence of a temperature gradient alone.

Structural Changes of Mo/ZSM-5 Catalysts During the Methane Dehydroaromatization

Eurasian Chemico-Technological Journal, 2010
The structure changes of Mo/ZSM-5 catalysts with different Mo content (2 and 10 wt. % Mo) and Si/Al atomic ratio (17, 30 and 45) during the methane dehydroaromatization have been investigated by X-ray powder diffractometry, N2 adsorption and transmission

Tuning graphitic oxide for initiator- and metal-free aerobic epoxidation of linear alkenes

Nature Communications, 2016
Graphitic oxide is readily produced by the oxidation of graphite. Here the authors show that the amount and nature of the oxidant can be used to tune the properties of graphitic oxide, and furthermore report a carbocatalyst for alkene epoxidation without

Nitrogen Doped Carbon Nanotubes and Nanofibers for Green Hydrogen Production: Similarities in the Nature of Nitrogen Species, Metal–Nitrogen Interaction, and Catalytic Properties

Energies, 2019
The effect of nitrogen doped bamboo-like carbon nanotubes (N−CNTs) on the properties of supported platinum (0.2 and 1 wt %) catalysts in formic acid decomposition for hydrogen production was studied.

Magnetic catalysis and inverse magnetic catalysis in QCD [PDF]

arXiv, 2015
We investigate the effects of strong magnetic fields on the QCD phase structure at vanishing density by solving the gluon and quark gap equations, and by studying the dynamics of the quark scattering with the four-fermi coupling. The chiral crossover temperature as well as the chiral condensate are computed.

Inverse magnetic catalysis in field theory and gauge-gravity duality

, 2012
We investigate the surface of the chiral phase transition in the three-dimensional parameter space of temperature, baryon chemical potential and magnetic field in two different approaches, the field-theoretical Nambu-Jona-Lasinio (NJL) model and the ...

Methane dry reforming over Ni catalysts supported on Ce–Zr oxides prepared by a route involving supercritical fluids

Open Chemistry, 2017
Ce0.5Zr0.5O2 mixed oxides were prepared in a flow reactor in supercritical isopropanol with acetylacetone as a complexing agent. Variation of the nature of the Zr salt and the temperature of synthesis affected the phase composition, morphology and ...

Laguerre polynomial excited coherent states generated by multiphoton catalysis: Nonclassicality and Decoherence [PDF]

arXiv, 2015
We theoretically introduce a new kind of non-Gaussian state-----Laguerre polynomial excited coherent states by using the multiphoton catalysis which actually can be considered as a block comprising photon number operator. It is found that the normalized factor is related to the two-variable Hermite polynomials.
