5,10,15,20-Tetrakis(pentafluorophenyl) [22]pentaphyrin(1.1.1.1.1) 7 was synthesised and its bis-rhodium(I) complex 12 has been revealed to be a non-fused, yet planar pentaphyrin with an inverted pyrrole. Both 7 and 12 are aromatic, showing sharp Soret-like bands and diatropic ring currents.

For an ionic melt consisting of two components and of three ion constituents, we derive the interrelation between the Soret coefficient and the initial and final values of the thermoelectric power of a thermocell containing the melt considered. We only use the general formulas of Thermodynamics of Irreversible Processes and there is no restriction with respect to the valency types of the electr...

Novel ionic water-soluble tetrabenzoporphyrins have been successfully synthesized via a cascade reaction based on the Heck reaction. The UV-Vis spectra of these porphyrins displayed red-shifted and broadened Soret bands, and significantly enhanced Q bands. These porphyrins are highly water soluble.

Abstract In this short paper, some analytical results found in “Double-diffusive Soret convection phenomenon porous media: effect of Vadasz inertia term” by F. Capone, R. De Luca, M. Vitiello, Ricerche Mat. 68, 581–595 (2019), are recalled order to better explore the dynamic thermosolutal a horizontal layer with influence and terms.

T he Soret effect, also known as thermodiffusion, is a classic example of coupled transport (1) in which directed motion of a particle or macromolecule is driven by f low of heat down a thermal gradient. Generally, a particle moves from hot to cold, but the reverse is also seen under some conditions. Although it has been known for 150 years, the microscopic explanation of the Soret effect has r...

Unsteady viscous two-dimensional magnetohydrodynamic micropolar flow, heat and mass transfer from an infinite vertical surface with Hall Ion-slip currents is investigated theoretically numerically. The simulation presented motivated by electro-conductive polymer (ECP) materials processing in which multiple electromagnetic effects arise. primitive boundary layer conservation equations are transf...

We set up a discrete space-time dynamical model of molecules with thermalised kinetic energy and repulsive cores, in an external potential. The model obeys the first and second laws of thermodynamics. The continuum limit, obtained using a MAPLE program, gives rise to coupled reaction-diffusion equations for the density and temperature fields. The system obeys Onsager symmetry and exhibits the S...

The motion of non-Newtonian fluid with heat and mass transfer through porous medium past a shrinking plate is discussed. obeys Casson model, generation, viscous dissipation, thermal diffusion, chemical reaction are taken in our considered. modulated mathematically by system non-linear PDE which describe the continuity, momentum, heat, equations. These equations transformed into ODE using suitab...
