A comparative study of complexation behaviour of three tetracycline derivatives viz. doxycycline hydrochloride, oxytetracycline hydrochloride and minocycline hydrochloride with β-cyclodextrin (β-CD) has been done with the help of various thermodynamic and spectroscopic methods. Density (ρ) and conductivity measurements have been carried out for binary drug/water and ternary drug/water/(β-CD) systems at three different temperature viz. 305.15, 310.15 and 315.15 K. The interactions of these tetracycline derivatives with β-cyclodextrin in aqueous solutions are further studied by means of fluorescence spectroscopy and UV-visible spectroscopy. From the measured density (ρ) data, partial molar volume (Φ°ν), partial molar volume expansibility (ϕ°e), Hepler′s constant (∂2ϕ°ν / ∂T2)P and partial molar volume of transfer (Δϕ°ν) have been obtained. From the conductance studies, the energetically favourable interactions are interpreted in the form of free energy change (ΔG) and the apparent association constant (Ka) was estimated from the fluorescence data.

Nanostructures of iron oxide and doped iron oxide with cobalt (Co), nickel (Ni) and zinc (Zn) have been prepared by wet chemical methods using sodium dodecyl sulphate (SDS) as capping agent. X-ray diffraction (XRD) and high resolution transmission electron microscopy (HRTEM) results showed that the nanostructures were crystalline with average crystallite size around 20 nm. The scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images confirmed the granular shape of the nanostructures with ultra small size. The doping was confirmed in the XRD patterns and was well supported by Fourier transform infrared spectroscopy (FTIR). Band gap for iron oxide nanoparticles was found to be 2.2 eV and on doping the band gap found to be increased up to 2.5 eV. Ultra violet-visible (UV-Vis) measurements and blue shift of the optical band gap compliments the ultra small size of nanostructures as suggested by XRD, SEM and TEM studies. Interestingly, few of the compounds showed promising antifungal activity and might be used for antifungal treatment against fungal infection in future. ARTICLE HISTORY

“…Limiting molar conductance, association constant and distances of closest approach of ions in the mixed solvents have been calculated by using the conductance data in low concentration chemical model (lcCM) [20]. Ionic conductivity values for K + , Li + , Ag + [21]. It was observed that limiting molar conductance values increase with increasing temperature which may be attributed to the increasing ionic mobility at higher temperatures.…”

The study of ion- solvent interaction is of much importance to investigate the nature of different solutions. Measurement of electrical conductivity and evaluation of physico-chemical properties, such as molar conductance, limiting molar conductance, ion-pair association, Walden product etc. shade light on different intermolecular interactions present in electrolyte solutions. Solvation properties can be varied by mixing two or more solvents. An extensive literature survey on conductometric studies has been carried out on different electrolytes dissolved in a wide range of mixed solvent systems. The reported results show that strong solute-solute, solute-solvent and solvent-solvent interactions are responsible for the physico- chemical behavior of a solution in mixed solvents.
