This paper aims to analyze the thermal performance of four different heat transfer fluids in a hot oil system located paraffin hydrotreatment and fractionation plant petroleum refinery. The software Petro-SIM? (KBC- -Yokogawa) was employed elaborate steady-state simulations intended compare fluid currently used (eutectic biphenyl diphenyl oxide) three proposed as substitutes: (namely n-C13 +) p...

The exchange interaction, J, between two spin centres is a convenient measure of through bond electronic communication. Here, we investigate quantum interference phenomena in a bis-copper six-porphyrin nanoring by electron paramagnetic resonance spectroscopy via measurement of the exchange coupling between the copper centres. Using an analytical expression accounting for both dipolar and exchan...

New donor building blocks, i.e., triarylamino derivatives, are of great interest for the production organic photovoltaic materials. In this communication, bis(4′-(hexyloxy)-[1,1′-biphenyl]-4-yl)amine was synthesized in a two-step process via hydrolysis its tert-butyl carbamate derivative. tert-Butyl bis(4′-(hexyloxy)-[1,1′-biphenyl]-4-yl)carbamate obtained by Suzuki cross-coupling reaction bis(...
