Thermodynamic length is a metric distance between equilibrium thermodynamic states that asymptotically bounds the dissipation induced by finite time transformation of system. By means length, we first evaluate departures from ideal to real gases in geometric thermodynamics with and without Legendre invariance. In particular, investigate Ruppeiner geometrothermodynamic formalisms. Afterwards, fo...

In this study, the ion association phenomenon in the saturated solution of KCl in the mixed solvent(methanol+water) was studied. The solubility of this compound in the mixed solvent (methanol+water by value percent of methanol = 60%), and in the presence of various molarities of NaNO3 wasdetermined by the solvent evaporation method at 25.0°C. The results enable us to estimate the valueof thermo...

Molecular weights (molar masses), molecular weight distributions, dissociation constants and other interaction parameters are fundamental characteristics of proteins, nucleic acids, polysaccharides and glycoconjugates in solution. Sedimentation equilibrium analytical ultracentrifugation provides a powerful method with no supplementary immobilization, columns or membranes required. It is a parti...

In this paper, we present a physics-based analytical model of GNR FET, which allows for the evaluation of GNR FET performance including the effects of line-edge roughness as its practical specific non-ideality. The line-edge roughness is modeled in edge-enhanced band-to-band-tunneling and localization regimes, and then verified for various roughness amplitudes. Corresponding to these two regime...

Analytical ultracentrifugation is a free solution technique with no supplementary immobilization, columns or membranes required, and can be used to study self-association and hetero-interactions, stoichiometry, reversibility and interaction strength across a very large dynamic range (dissociation constants from 10(-12) M to 10(-1) M). In the present paper, we review some of the advances that ha...
