Oxygen is then added to the system. Any oxidation that occurs is observed as a deviation in the baseline. Such analysis can be used to determine the stability and optimum storage conditions for a material or compound. [15] DSC equipment can also be used to determine the Oxidative-Onset Temperature (OOT) of a material.
Polymers represent another large area in which thermal analysis finds strong applications. Thermoplastic polymers are commonly found in everyday packaging and household items, but for the analysis of the raw materials, effects of the many additive used (including stabilisers and colours) and fine-tuning of the moulding or extrusion processing used can be achieved by using differential scanning ...
Thermomechanical analysis (TMA) is a technique used in thermal analysis, a branch of materials science which studies the properties of materials as they change with temperature. Thermomechanical analysis is a subdiscipline of the thermomechanometry (TM) technique.
Characteristic DSC curve for a polyethylene, the OIT is measured. Oxidation induction time or OIT is a standardized test performed in a DSC which measures the level of thermal stabilization of the material tested. The time between melting and the onset of decomposition in isothermal conditions is measured.
I think on the DSC graph the peaks and valley which correspond to crystallization and melting are switched. THe peak should be melting and the valley be crystallization. 130.49.144.110 21:27, 26 October 2010 (UTC) I was just going to make that observation ... Abtract 16:52, 21 January 2012 (UTC)
Microsoft Graph supports many different types of charts, but its output is dated. Office 2003 was the last version to use Microsoft Graph for hosting charts inside Office applications as OLE objects. Office 2007 – specifically, Excel 2007 – includes a new integrated charting engine, and the charts are native to the applications. The new ...
A bond graph is a graphical representation of a physical dynamic system. It allows the conversion of the system into a state-space representation . It is similar to a block diagram or signal-flow graph , with the major difference that the arcs in bond graphs represent bi-directional exchange of physical energy , while those in block diagrams ...
In mathematics, the concept of graph dynamical systems can be used to capture a wide range of processes taking place on graphs or networks. A major theme in the mathematical and computational analysis of GDSs is to relate their structural properties (e.g. the network connectivity) and the global dynamics that result.
