DSC is one of .In this work the microstructure of a commercial Al-Cu alloy (2 0 1 1) in several metallurgical states has been studied by means of differential scanning calorimetry (DSC). The metallurgical states were chosen in such a way that the alloy contained predominantly one of the four possible phases in these alloys (i.e. GP zones andθ″,θ′ andθ phases). The commercial tempers T3 . Differential scanning calorimetry was also tested as a potential tool for discriminating five olive oil commercial categories i.e. extra virgin olive oil (EVOO), refined olive oil (ROO), olive oil . Differential scanning calorimetry thermograms of five commercial categories of olive oils (extra virgin olive oil, olive oil, refined olive oil, olive-pomace oil and refined olive-pomace oil) were performed in both cooling and heating regimes. Overlapping transitions were resolved by deconvolution a .

A method for rapid quantitative analysis of the content and distribution of short chain branching (SCB) for α-olefin/ethylene copolymers based on thermally fractionated DSC is presented. Eight commercial polyethylenes, four made with conventional Ziegler-Natta catalysts and four made with metallocene catalysts, were analyzed by differential .Abstract. Chip-based fast scanning calorimetry (FSC) or chip-calorimetry based on MEMS-sensor technology nowadays enables constant heating and cooling rates from 10 2 up to more than 10 9 K/min on micro- to nanogram samples, respectively, as measured between − 150 and 1000 °C. Evidently, fast processes – like applied in production during cooling – can now be .
Differential scanning calorimetry (DSC) is often used as a quality control tool to characterize MgSt, but little data is available regarding the physicochemical relevance for the DSC thermograms. A method for rapid quantitative analysis of the content and distribution of short chain branching (SCB) for α-olefin/ethylene copolymers based on thermally fractionated DSC is presented. Eight commercial polyethylenes, four made with conventional Ziegler-Natta catalysts and four made with metallocene catalysts, were analyzed by differential .
