To improve the understanding of the relation between composition, precipitation and the balance of strength and electrical conductivity (as a measure of the stress-corrosion resistance), a number of Al-Zn-Mg-Cu-Zr aluminium alloy plates with different Zn, Mg and Cu contents were produced and studied by Differential Scanning Calorimetry (DSC). It is shown that detailed analysis of the DSC data p...

The differential scanning calorimetry (DSC) behavior of a number of alkyne-rich compounds is described. The DSC trace for each compound exhibits an exothermic event at a characteristic onset temperature. For the tri- and tetraynes whose [4 + 2] HDDA reactivity in solution has been determined, these onset temperatures show a strong correlation with the cyclization activation energy. The studies ...

Figure 1: Raw data with calculation Differential Scanning Calorimetry (DSC) is used to measure heat flow into or out of a sample as it is exposed to a controlled thermal profile. DSC provides both qualitative and quantitative information about material transitions such as the glass transition, crystallization, curing, melting, and decomposition. For some of these transitions, DSC can provide no...

Palladium nanoparticles encapsulated into graphite (Pd–graphite intercalation compound: Pd–GIC) were produced from two kinds of graphite, natural graphite (average flake size: 270 mm) and kish graphite (average flake size: 15 mm). Hydrogen storage properties of Pd– GIC have been investigated by means of differential scanning calorimetry (DSC) between 473 and 573 K at 1.0 MPa hydrogen pressure. ...

Differential Scanning Calorimetry (DSC) is used to measure heat flow into or out of a sample as it is exposed to a controlled thermal profile. DSC provides both qualitative and quantitative information about material transitions such as the glass transition, crystallization, curing, melting, and decomposition. For some of these transitions, DSC can provide not only the temperature at which the ...

A composite of cellulose extracted from bagasse with Nb2O5·nH2O in three different proportions (16.67, 37.5 and 50.0 wt%) was prepared using the co-precipitation method. The materials were characterized by X-ray diffractometry (XRD), Fourier transform infra-red spectroscopy (FTIR), thermogravimetric analysis (TG/DTG), differential scanning calorimetry (DSC) and scanning electron microscopy (SEM...

in this study, confined impinging liquid jets are used to produce nanoparticles of carbamazepine (cbz). the effect of operating parameters, such as the kind of solvent,cbz concentration, flow rate of solution and antisolvent on particle size, are experimentally investigated. the scanning electron micrograph (sem) photomicrographs show that nanodrug with smaller particle is achievable by using s...

M. Torres-Lopez, L. Guerra-Fuentes, L. Y. Gomez-Zamorano, M. A. L. Hernandez-Rodriguez, E. Garcia-Sanchez. University Autonomous of Nuevo Leon. Thermal analysis in a PREMOMET® steel has been performed by differential scanning calorimetry (DSC) and highresolution dilatometry. The phase transformation temperatures (Ac1, Ac3, Ms and Mf) of this steel were obtained by the two methods at different h...
