Several papers have been described on the thermal stability of the sweetener, C12H19Cl3O8 (Sucralose). Nevertheless no study using thermoanalytical techniques was found in the literature. Simultaneous thermogravimetry and differential thermal analysis (TG-DTA), differential scanning calorimetry (DSC) and infrared spectroscopy, have been used to study the thermal stability and thermal decomposit...

Background: Thermal stability (TS) is a part of the BCG vaccine characterization by which the consistency of process in BCG vaccine production could be confirmed. To enhance the TS of the vaccine, some prevalent stabilizers in different concentrations were added to the final formulation of BCG bulk prior to Freeze-drying process. We found a formulation more effective than the current stabilizer...

background: enzymes are well known as sensitive catalysts in the laboratory and industrial scale. to improve their properties and for using their significant potential in various reactions as a useful catalyst the stability of enzymes can often require improvement. enzymes immobilization on solid supports such as epoxy- functionalized ferric silica nanocomposite can be effective way to improve ...

A 0-dimensional model with parabolic profiles is employed to assess the use of the combination of enhanced thermal conduction loss and radial motion for passive thermal stability control of an ignited tokamak plasma. The increases in ignition requirements needed for the achievement of passive stability are determined. Both the independent thermal stabilization effects of radial motion and enhan...

Tij and Delta Hij for stacking of pair i upon j in DNA have been obtained over the range 0.034-0.114 M Na+from high-resolution melting curves of well-behaved synthetic tandemly repeating inserts in recombinant pN/MCS plasmids. Results are consistent with neighbor-pair thermodynamic additivity, where the stability constant, sij , for different domains of length N depend quantitatively on the pro...

Abstract: The investigation is carried out to characterize welding of AISI 310 austenitic stainless steel to Inconel 657 nickel-chromium superalloy. The welds were produced using four types of filler materials: the nickel-based corresponding to Inconel 82, Inconel A, Inconel 617 and austenitic stainless steel 310. This paper describes the effects of aging treatment on the joint. The compara...

Background and Aims: The safe, potent and effective live vaccines against Measles, Mumps and Rubella as important childhood diseases have been available for several decades. Several factors can affect the thermal stability of lyophilized vaccine. Methods: In this study, the effect of residual moisture on thermal stability of 61 batches of MMR vaccine was investigated using an accelerated ...
