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

Chimica 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.

Inverse Magnetic Catalysis in Bottom-Up Holographic QCD

, 2016
We explore the effect of magnetic field on chiral condensation in QCD via a simple bottom up holographic model which inputs QCD dynamics through the running of the anomalous dimension of the quark bilinear.

Vinylic Addition Polynorbornene in Catalysis [PDF]

, 2019
Vinylic addition polynorbornenes (VA-PNB) result from the insertion polymerization of norbornene or specific norbornene derivatives catalyzed by transition metal com- plexes. The VA-PNB skeleton is completely aliphatic and keeps the bicyclic structure of

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.
