The properties and cost have made the Nickel-Titanium (NiTi) shape memory alloys (SMA) attractive for a variety of applications wherein shape memory effect (SME) / superelasticity (SE) and biocompatibility are important. Anisotropy of the shape recovery associated with shape memory effect strongly depends on the type of r 30 minutes in air) Ti-Rich Ni-Ti SMA (Ni51at%Ti) when subjected to cold r...

3,4-Bis(1H-5-tetrazolyl)furoxan (H(2)BTF, 2) and its monoanionic salts that contain nitrogen-rich cations were readily synthesized and fully characterized by multinuclear NMR ((1)H, (13)C) and IR spectroscopy, differential scanning calorimetry (DSC), and elemental analyses. Hydrazinium (3) and 4-amino-1,2,4-triazolium (7) salts crystallized in the monoclinic space group P2(1)/n and have calcula...

The number of water molecules bound (unfreezable) by a molecule of dipalmitoyl phosphatidylserine (DPPS) or by a molecule of dipalmitoyl phosphatidylcholine (DPPC) alone or in mixtures with cholesterol was determined by differential scanning calorimetry (DSC). When the phospholipids are in the gel state and in the absence of cholesterol, molecule of DPPS binds about 3.5 molecules of water and m...

Effect of aging on successive martensitic transformation in a Ti–47 at%Pd shape memory alloy has been studied by means of differential scanning calorimetry (DSC) and transmission electron microscopy (TEM). After short time aging successive transformation takes place in Ti–47 at%Pd alloy irrespective of aging temperature. On the other hand, after relatively prolonged period only the specimen age...

We present the spatial architecture of a new anhydrous polymorph of Acyclovir, obtained by rapid evaporation of a solution composed of Acyclovir and methanol. X-ray powder diffraction (XRPD), solid-state NMR (SSNMR), differential scanning calorimetry (DSC), and FTIR spectroscopy have been used as experimental tools to prove the formation of this new solid form and to characterize its crystallin...

Films of EVOH copolymers, processed three times by twin-screw extrusion were prepared using a cast-film line. The variation on the melt flow rate (MFR) and rheological behaviour of the films were determined, as well as the thermal properties assessed by differential scanning calorimetry (DSC) and dynamic-mechanical thermal analysis (DMTA). As the results showed that the reprocessing induced an ...

The objective of this study is to use differential scanning calorimetry (DSC) to characterize the curing kinetics of Al2O3 and hydroxyapatite suspensions in acrylates. The heat evolution of the acrylate premix and ceramic suspensions in dynamic and isothermal curing was measured. The calculated activation energies for the acrylate premix and the two ceramic suspensions were 133, 74, and 78 kJ/m...

Thiol-capped silver nanoparticles were prepared by in situ thermal decomposition of different silver(I)-thiolates precursors in a polymeric matrix. Depending on the structure of the organic coating, contact-free distribution of metal nanoparticles or nanoparticles aggregates were achieved. The structure and morphology of nanocomposites was analyzed by Transmission Electron Microscopy (TEM), and...

Polymerization of β-phenyl glutaconic diethyl ester (GE) with various diamines (DA) at 1:2 molar ratios in 1,4dioxane solvent was carried out at reflux temperature. The resultant amino terminated unsaturated oligomers (ATUP) were characterized by elemental analysis, number of terminal amino groups, IR spectral studies, number average molecular weight estimated by non-aqueous conductometric titr...

The Chalcogenide glasses were fabricated by melting and quenching techniques in the Se-Ge system at the presence of 1mol% Ga and 3, 5, and 7mol% Sn. Differential Scanning Calorimetry (DSC) analysis was conducted to extract the heat treatment of the samples. Fourier Transform Infrared (FTIR) spectroscopy analysis was also performed in a range of 2-16µm. The Glass samples were heat-treated at 450...
