Thermal stability of the martensitic transformation of Cu-Al-Ni-Mn-Ti
(Elsevier B.V., 2006-12-25)
The development of new shape memory alloys with high martensitic transformation temperature increases the potential for applications. The development and use of these new alloys depends on the stability of the structure ...
Peroxidase from peach fruit: Thermal stability
(Inst Tecnologia Parana, 1998-01-01)
Peroxidase from peach fruit was purified 28.9-fold by DEAE-cellulose, Sephadex G-100 and hydroxylapatite chromatography. The purified enzyme showed only one peak of activity with an optimum pH of 5.0 and temperature of 40 ...

Influence of Chromium (III) Insertion on the Thermal Stability of Carbonated Magnesium and Aluminum Hydrotalcites Synthesized by the Hydroxide Coprecipitation Method
(Univ Federal Mato Grosso Sul, Dept Quimica, 2018-01-01)
Anionic clays are structures capable of adsorbing large quantities of water and other polar molecules in aqueous medium due to an ordered lamellar arrangement. Generally, the most stable composition contains magnesium and ...
Evaluation of thermal stability and sun protector factor values in vitro in O/W emulsions containing Benzophenone-3 and Avobenzone
(Colegio de Farmacéuticos de la Provincia de Buenos Aires, 2013-12)
The purpose of this work is to study the thermal stability of benzophenone-3 and avobenzone in the presence and in the absence of TiO2, in O/W emulsions for sunscreens products. The emulsions were stored in glass containers ...
Thermal and structural investigation of Er:YAl(3)(BO(3))(4) nanocrystalline powders
(SPRINGER, 2009)
Pure Er:YAB (Er:YAl(3)(BO(3))(4)) nanometer-sized crystalline powder was produced from low cost chemical route, the polymeric precursor method. The initial homogeneous solutions were heat treated from 200 to 700A degrees ...
Thermal behaviour of α-hydroxyisobutyric acid, sodium α-hydroxyisobutyrate and its compounds with some bivalent transition metal ions

Synthesis, characterization and thermal decomposition of bivalent transition metal α-hydroxyisobutyrates, M(C4H7O 3)2·nH2O (M = Mn(II), Fe(II), Co(II), Ni(II), Cu(II), Zn(II)), as well as the thermal behaviour of ...
Cetyltrimethylammonium chloride (CTAC) effect on the thermal stability of oxy-HbGp: Dynamic light scattering (DLS) and small angle X-ray scattering (SAXS) studies
(Elsevier B.V., 2014-06-01)
Glossoscolex paulistus (HbGp) hemoglobin is an oligomeric protein, displaying a quaternary structure constituted by 144 globin and 36 non-globin chains (named linkers) with a total molecular mass of 3.6 MDa. CTAC effects ...
Thermal behavior of some antihistamines
(2013-03-01)
Thermogravimetry (TG), differential scanning calorimetry (DSC), polarized light thermal microscopy (PLTM), as well as X-ray powder diffraction (XRD) and Fourier transformed infrared spectroscopy (FTIR) were used to study ...
Bioactive constituents in liposomes incorporated in orange juice as new functional food: thermal stability, rheological and organoleptic properties
(Association of Food Scientists and Technologists of India, 2015-12)
Liposomes were developed with bioactive constituents (omega-3, omega-6, tocopherol) incorporated in acid food. They were made of soy phosphatidylcholine (SPC) allowing the encapsulation of antioxidant vitamin C (VC) and ...
