In the present work, kinetic and thermodynamic analysis of ficus wood was carried out using thermogravimetric (TGA). Thermal degradation has been evaluated under dynamic conditions from 373 K to 1173 at heating rates 5, 10, 20, 50 K.min?1. The performed isoconversional methods (Friedman (FR), Flynn-Wall-Ozawa (FWO) Vyazovkin (VYA)) integral master-plots method estimate triplets. data were used ...

in this study, the adsorption of 4-hydroxy phenyl-azobenzene on the surface of (4, 0) zigzag open-end boron nitride nanotube (bnnt) has been investigated by quantum calculations. in order to find the preferred adsorption site, different positions and orientations were considered. the impacts of donor-acceptor electron delocalization on the structural and electronic properties and reactivity of ...

In this study, aggregation behavior of a water soluble cationic metalloporphyrin, meso-tetrakis (2,3,5,6-tetrafluoro-N,N´,N´´-trimethyl ammonium phenyl) porphyrin nickel(II) [Ni(II)(TF4TMAPP)]4+ is investigated in 5 mM aqueous phosphate buffer of pH 7.0 at 25.0 °C and various ionic strengths using optical absorption and resonance light scattering spectroscopic methods. The...

Porophyrins and their metal derivatives are strong DNA binders with association constant of  to  . Some of these compounds have been used for the radiations sensitization therapy of cancer and are targeted to interact with cellular DNA. Binding of porphyrins to DNA changes the expectral and other physic chemical characteristic of porphyrins, The mode of binding can be extracted from inspection ...

The judicious tuning of simple thermodynamic parameters controlling dimerization processes in solution induces a rational switch between smectic and nematic organizations in thermotropic lanthanide-containing liquid crystals.

Monovalent ligand and divalent ligand have been synthesized, and their thermodynamic parameters of complexation to avidin and streptavidin have been analyzed in terms of multivalent binding.

The solution of the associative mean-spherical approximation for iondipolar system is reinvestigated and expressed in terms of only five parameters. Three of them have counterparts in the case without association, and the other two are the monomer fractions of ions and dipoles. The explicit expressions for the thermodynamic quantities are represented in a simpler form. Numerical results for the...

Introduction Glycine having three polymorphs (α, β and γ) at ambient conditions differs in the arrangement of zwitterions in the hydrogen-bonding network and the physical and chemical properties. For insight into the differences in the relative thermodynamic stability of the glycine polymorphs, we apply a novel method of concurrent analysis of multi-temperature atomic displacement parameters (A...
