Thermally Induced Structural Changes in Immunoglobulin E

Thermally induced structural changes in immunoglobulin E.

The ability of immunoglobulin E (IgE) to bind to the cell membrane of basophiles and mast cells is progressively lost when the molecule is heated at 56”. In the present study, we have investigated the structural changes induced by heating under conditions known to destroy this biological function, although direct measurements of cytotropic activity were not made. After 30 min at 56” circular di...

Thermally Induced Structural Changes in Coal Combustion

It has been observed that certain char particles shrink when oxidized under kinetically limited conditions, instead of reacting at constant diameter, as expected. This study was perfonned to determine whether or not char from PSOC 1451 coal, prepared at different temperatures would also shrink during low temperature gasification. Coal chars, formed at l 200K and 1600K, were levitated in the ele...

Thermally induced structural and morphological changes of CdSe/CdS octapods.

Branched nanostructures are of great interest because of their promising optical and electronic properties. For successful and reliable integration in applications such as photovoltaic devices, the thermal stability of the nanostructures is of major importance. Here the different domains (CdSe cores, CdS pods) of the heterogeneous octapods are shown to have different thermal stabilities, and he...

Thermally induced structural transformations on polymorphous silicon

Polymorphous Si is a nanostructured form of hydrogenated amorphous Si that contains a small fraction of Si nanocrystals or clusters. Its thermally induced transformations such as relaxation, dehydrogenation, and crystallization have been studied by calorimetry and evolved gas analysis as a complementary technique. The observed behavior has been compared to that of conventional hydrogenated amor...
