‏‎suppression of coke formation in thermal cracking by coke inhibitors‎‏

‏‎the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...

Submicron Spatial Resolution in Thermal Desorption Mass Spectrometry via Rapid Heating Functions using Thermal AFM Probes

Atomic Force Microscopy (AFM) combined with Mass Spectrometry (MS) can provide the ability to map and correlate the molecular and physical properties of samples [1, 2] at sub-micron resolutions. Our group has demonstrated such a platform using heated AFM probes [3] for the thermal desorption (TD) of molecules. Current heating techniques typically result in a minimum desorption crater diameter o...

Thermal conductivity of neutrons in neutron star cores

The diffusive thermal conductivity of neutrons in dense matter [ρ ∼ (1−8)×10 g cm] of neutron star cores is calculated. The contribution from neutron–neutron and neutron–proton collisions is taken into account. We use the transition probabilities calculated for symmetric dense nucleon matter on the basis of the Dirac– Brueckner approach to the in-medium effects and the Bonn model of bare nucleo...
