TL;DR: In this article, the thermal properties, crystallization behavior, glass forming ability and mechanical properties of Ti-based amorphous alloys were studied by using differential scanning calorimetry (DSC), X-ray diffractometry, transmission electron microscopy and compressive test.
Abstract: The thermal property, crystallization behavior, glass forming ability (GFA) and mechanical properties of Ti-based amorphous alloys were studied by using differential scanning calorimetry (DSC), X-ray diffractometry, transmission electron microscopy and compressive test. These alloys were developed systematically by considering atomic size and interaction parameters between constituting elements. Partial replacement of Cu by Be and Ti by Zr in Ti–Cu–Ni–Sn alloy improved the GFA. Fully amorphous rods, of diameter 2, 5 and 8 mm, could be fabricated by injection casting Ti 50 Cu 25 Ni 15 Sn 3 Be 7 , Ti 45 Cu 25 Ni 15 Sn 3 Be 7 Zr 5 and Ti 40 Zr 25 Ni 8 Cu 9 Be 18 alloys, respectively. The T rg (= T g / T l ) and γ (= T x /( T g + T l )) parameter shows a relatively good agreement with the maximum diameter of bulk glass, while Δ T x has poor relationship with the GFA of alloys. The bulk amorphous alloys exhibit high compressive strength of approximately 2500 MPa with good ductility.

TL;DR: Immediate and complete release of ibuprofen from SDs might be because of the reduction in the drug crystalline due to eutectic formation, and their dosing to fasted rats resulted in a significant increase in the area under curve (AUC) of the plasma concentration versus time curve and the maximum plasma concentration (Cmax), and a significant decrease in the time to reach Cmax over ib uprofen and physical mixtures.

TL;DR: Spectroscopic investigation for the presence of interaction between the drugs and PVP proved to be extremely predictive of the plasticizing effect of various drugs, and solubility parameters appeared to be far less sensitive indicators of drug-PVP miscibility.

TL;DR: In this paper, the thermal stability of electroplated nanocrystalline Ni of 10 and 20 nm grain size was investigated by differential scanning calorimetry (DSC).
Abstract: Thermal stability of electroplated nanocrystalline Ni of 10 and 20 nm grain size was investigated by differential scanning calorimetry (DSC). The temperature dependence and heat release ΔH during grain growth have been determined by linear anisothermal measurements (linear heating at 10 K min −1 ). The corresponding change in microstructure has been monitored in the temperature range between 373 K and 693 K using transmission electron microscopy (TEM). The TEM and DSC studies identified three exothermic reactions: “nucleation” and abnormal grain growth (353–562 K), normal grain growth (562–593 K) and growth towards equilibrium (643–773 K). The grain growth behaviour, and the similar heat releases ΔH = 18 J g −1 , and 16 J g −1 measured for the 10 nm and 20 nm Ni nanocrystals respectively in the DSC experiments may be related to the observed sulphur segregation at grain boundaries and triple junctions.
