Room temperature dielectric and antibacterial behavior of thiosemicarbazide capped low dimension Silver and Gold nanoparticles were studied. The effect of size on the properties, by capping silver (Ag) and gold (Au) nanoparticles by thiosemicarbazide (TSC) was investigated. The nanoparticles were synthesized by chemical reduction method. The structural formation, surface morphology, phase stabi...

The effects of ultraviolet (254 nm) radiation on a hydrated gelatin-glucose matrix were investigated for the development of a physiologically thermostable substrate for potential use in cell scaffold production. Experiments conducted with a differential scanning calorimeter indicate that ultraviolet irradiation of gelatin-glucose hydrogels dramatically increases thermal stability such that no m...

The kinetics of the solution polymerization of methyl-methacrylate is characterized by a strong increase of viscosity up to 6 orders of magnitude and auto-acceleration of the reaction rate due to the gel-effect. This can lead to thermal and kinetic reactor instabilities. The kinetics were determined separately using a differential scanning calorimeter and described with a modified published mod...

Cellulose hydrogels with quaternary ammonium (QA) groups were prepared via the etherification and cross-linking reaction. The structure of the functional hydrogels with QA groups was confirmed with FT-IR. Differential scanning calorimeter (DSC) analysis indicated that there was a large amount of free water in the hydrogels. The hydrogels showed salt-sensitivity behavior, and they also exhibited...

poly(ethylene adipte) and poly(ethylene adipate)/silica nanocomposite (pead/sio2) containing 3 wt. % sio2  were prepared by an in situ method. the examinations on the non-isothermal crystallization kinetic behavior have been conducted by means of differential scanning calorimeter (dsc). the avrami, ozawa, and combined avrami and ozawa equations were applied to describe the crystallization kinet...

We have developed a new thin-film differential scanning calorimetry technique that has extremely high sensitivity of 0.2 nJ. By combining two calorimeters in a differential measurement configuration, we have measured the heat capacity and melting process of Sn nanostructures formed via thermal evaporation with deposition thickness down to 1 Å. The equivalent resolution of the calorimeter is 1 n...
