High impact information on Differential Thermal Analysis

• Mixtures of dipalmitoylphosphatidylcholine (DPPC) with palmitic, stearic, and myristic acids and the sodium salts of these acids were analyzed by differential thermal analysis (DTA) over a wide range of lipid compositions, all in excess water [1].
• Simultaneous thermogravimetric and differential thermal analysis (TGA/DTA) of the serpentine mineral lizardite was used to isolate a series of heat-activated materials as a function of residual hydroxide content at progressively higher temperatures [2].
• Measured enthalpy values for successive removal of water molecules at 31.7 +/- 1.0, 91.3 +/- 0.8, and 193 +/- 0.6 degrees C are the same, within experimental error, at 21.6 +/- 2.6 kJ (mol H(2)O)(-1), as determined from differential thermal analysis traces [3].
• Differential thermal analyses were performed on the powdered glasses at a heating rate of 20 degrees C/minute up to 1400 degrees C. Bars (4 x 8 x 25 mm) were cut from the ingots with a low-speed diamond saw, nucleated in the temperature range 600-650 degrees C for 1-2 h and crystallized in the temperature range 900-1000 degrees C for 4-6 h [4].
• The differential thermal analysis (DTA) profiles showed that both form I and form II have an endothermic peak which would relate to the release of hydrochloric acid [5].

Associations of Differential Thermal Analysis with chemical compounds

• Pressure study on thermal transitions of oleic acid polymorphs by high-pressure differential thermal analysis [6].
• Differential thermal analysis of aluminum hydroxide gel [7].
• Evidence that (+)-bupranolol interacts directly with myocardial beta-adrenoceptors. Control of optical purity with differential thermal analysis [8].
• The hydration characteristics of phosphatidylcholines and the effect of cholesterol on these were studied with differential thermal analysis and water vapour adsorption experiments [9].
• Propranolol: methacrylic acid copolymer complex is characterized by differential thermal analysis, and IR and UV spectroscopic methods [10].

Gene context of Differential Thermal Analysis

• According to the thermogravimetric analysis/differential thermal analysis (TGA/DTA) results, the title compound is thermally stable up to ca. 200 degrees C [11].
• Differential thermal analysis (DSC) was performed in order to determine heats of fusion, melting points, and relative thermodynamic activities [12].

Analytical, diagnostic and therapeutic context of Differential Thermal Analysis

• A new Naringenin Schiff-base ligand (H3L) and its complex, [La(H2L)2(NO3).3H2O], have been synthesized and characterized on the basis of elemental analyses, molar conductivities, mass spectra, 1H NMR, thermogravimetry/differential thermal analysis (TG-DTA), UV spectra, and IR spectra [13].
• Using infrared spectroscopy, X-ray diffractometry, differential thermal analysis, scanning electron microscopy, solubility and dissolution rate measurements, it was demonstrated that the comminution of digoxin results in the appearance of an amorphous phase [14].
• Other methods for characterizing ACC include infrared spectroscopy, thermogravimetric analysis and differential thermal analysis (TGA and DTA), transmission electron microscopy (TEM), and electron and X-ray diffraction [15].
