Abstract In this paper, a new theoretical two-phase (solid–liquid) type model of melting temperature has developed based on the modified Gibbs–Thomson equation. Further, it is extended to derive other different size-dependent thermodynamic properties such as cohesive energy, Debye temperature, specific heat capacity, thermal and electrical conductivity metallic nanoparticles. Quantitative calcu...

the formation constants of the species formed in the systems h+ + cytidine 5
-monophosphate (cmp)and h+ + cytidine 5
-monophosphate + tl (i) ion have been determined in aqueous solution in a wideph range of 1.5 to 10.5 at 25 °c and different ionic strengths ranging from 0.1 to 1.5 moldm-3naclo4, nano3, and nacl using potentiometric-spectrophotometric technique. the composition ofthe complexes w...

It has been shown that the enzymic addition of valine to valine transfer ribonucleic acid (tRNA) of Escherichia co2i is exceedingly sensitive to alcohol or salt concentrations and that the rate of the reaction is predictable from the Debye-Htickel equations, if it is assumed that there are somewhat more than 4 positive charges and 4 negative charges involved in the rate-determining step. (For i...

Shear-mechanical and dielectric measurements on the two monohydroxy (monoalcohol) molecular glass formers 2-ethyl-1-hexanol and 2-butanol close to the glass-transition temperature are presented. The shear-mechanical data are obtained using the piezoelectric shear-modulus gauge method covering frequencies from 1 mHz to 10 kHz. The shear-mechanical relaxation spectra show two processes, which fol...

Electro-kinetic fluids can be modeled by hydrodynamic systems describing the coupling between fluids and electric charges. The system consists of a momentum equation together with transport equations of charges. In the dynamics, the special coupling between the Lorentz force in the velocity equation and the material transport in the charge equation gives an energy dissipation law. In stationary...

Recently an improved long-range model for electrolyte solutions was developed that is applicable from infinite dilution to pure salt. This paper tests this claim the first time applying it calculation of liquid-liquid equilibria mixtures different ionic liquids (ILs) and water. The conventional Pitzer-Debye-Hückel (PDH) equation compared two its new, thermodynamically consistent extensions. Bot...

Motivated by our recent proposition on the possibility of using dielectric continuum models to interpret experimental measurements of solvation dynamics in room temperature ionic liquids [J. Phys. Chem. A 110, 8623 (2006)], some detailed simulation studies are performed to test the validity of our proposition. From these simulation studies, it seems to be justified that an extended Debye-Hückel...
