The large availability of cellulose in nature and the low cost of cellulose derivatives make the cellulosebased hydrogels particularly attractive. New hydrogels were obtained by chemical cross-linking of different cellulose allomorphs (cellulose I, cellulose II and cellulose III) and xanthan with epichlorohydrin. The preparation conditions of the transparent cellulose hydrogels were established...

introduction: the aim of this study was to compare several metallurgic properties of neoniti instrument with four other commonly used endodontic rotary files. methods and materials: neoniti a1 (25/0.08), race (25/0.06), mtwo (25/0.06), twisted file (25/0.06) and protaper next x2 (25/0.06) were examined by differential scanning calorimetry (dsc) before and after heat treatment at 500 ° c. x-ray ...

Crystallization and morphological features of syndiotactic-b-atactic polystyrene stereodiblock copolymers (sPS-b-aPS), atactic/syndiotactic polystyrene blends (aPS/sPS), and aPS/sPS blends modified with sPS-b-aPS, with different compositions in aPS and sPS, have been investigated using differential scanning calorimetry (DSC), polarized light optical microscopy (POM) and wide angle X-ray diffrac...

Phase behavior and its effects on crystallization in an extruded poly(trimethylene terephthalate) (PTT)/phenoxy resin blend were studied with time-resolved light scattering (TRLS), optical microscopy (OM), differential scanning calorimetry (DSC), and small-angle X-ray scattering (SAXS). During annealing in the molten state, a two-phase structure with unique periodicity and phase connectivity wa...

The stability and thermal behaviour of two anhydrate phases and a new mixed water:DMSO solvate of Olanzapine (2-methyl-4-(4-methyl-1-piperazinyl)-10H-thieno-[2,3-b][1,5]benzodiazepine) are studied by different methods: differential scanning calorimetry (DSC), X-ray powder diffraction (XRPD) and Raman scattering (RS). Single crystal structural data for the latter phase are presented, confirming ...

Pharmaceutical availability of diazepam, oxazepam and nitrazepam from solid dispersions of PVP have been studied in comparison to those of the corresponding physical mixtures and pure benzodiazepines. The derivatives of 1,4-benzodiazepin-2-one are poorly water soluble drugs. The properties of diazepam-, oxazepam- and nitrazepam-PVP solid dispersions have been determined by the methods of differ...

The paper evidences changes of thermal properties of poly(methyl methacrylate) as well as methyl methacrylate copolymers with glycidyl methacrylate (GMA) polymers synthesized classic and comparatively in a magnetic field. Samples of poly(methyl methacrylate) and methyl methacrylate copolymers with different amounts of GMA synthesized by radical emulsion polymerization with or without the presen...

The thermoluminescence (TL) glow curves of UV irradiated PAAm-PVA polyblend have been studied. The experimental glow curves show the presence of two peaks with glow peak temperatures at 373K and 479K. The values of activation energy and frequency factors are determined by employing computer simulation. Most of the TL glow curves obey non first order kinetics. The results obtained by using TL ex...

In this study, we attempted to prepare carbamazepine (CBZ) cocrystal through the solution method in ethanol-water solvent mixture (volume ratio 1:1) and polyvinyl pyrrolidone (PVP) solution. Nicotinamide (NIC) and saccharin (SAC) were selected as cocrystal coformers. Cocrystal screening products were characterized by Fourier Transform Infrared Spectroscopy (FTIR), Differential Scanning Calorime...
