    DSC of etched aluminum foils for use in electrolytic capacitors (1997)
    Springer
    Journal of thermal analysis and calorimetry 49 (1997), S. 1305-1314 
    Details
    ISSN: 1572-8943
    Keywords: DSC ; electrolytic capacitors ; etched Al foils ; thermal resistance ; transient state
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract A DSC method for evaluating the surface area of etched Al foils for use in high performance electrolytic capacitors is presented. A linear relationship between the etching degree (effective surface area) and the thermal resistance of the sample is obtained by means of DSC, based on the transient phenomenon. This method using the transient state in DSC measurement is not only novel, but also rapid and simple in evaluating the surface area of an etched aluminum foil. The method is effective even when the Al foil has a naturally oxidized surface.

    Transient DSC, a Novel and Rapid Method for Assessing Pharmaceutical Powder Compacts (1999)
    Springer
    Journal of thermal analysis and calorimetry 56 (1999), S. 1311-1316 
    Details
    ISSN: 1572-8943
    Keywords: alumina ; aluminum oxide ; compact ; DSC ; particles ; pentaerythritol tetraacetate ; pharmaceuticals ; powder ; thermal resistance ; transient state
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract The previously described method involving the use of transient DSC was applied to pharmaceutical powder compacts and to ceramic powder compacts. The samples were prepared by compressing powders of pentaerythritol tetraacetate and two kinds of alumina powder (differing in particle size distribution) up to a pressure of 20 MPa by using a jig. For pentaerythritol tetraacetate, a linear relationship was obtained between the parameter obtained by DSC and the compaction pressure.

    Thermal analysis of powdered alumina materials (1997)
    Springer
    Journal of thermal analysis and calorimetry 49 (1997), S. 961-970 
    Details
    ISSN: 1572-8943
    Keywords: distribution constant ; DSC ; powder compact ; Rosin-Rammler particle size distribution ; thermal resistance
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract How a DSC result is influenced by the particle size distribution of a powder sample is shown, and a simple and optimal method to be included in a routine DSC analysis (e.g., purity determination) to improve the reliability of the analysis is proposed. In case ofα-Al2O3 powder, most reliable heat capacity data can be obtained by preparing a powder with a self-similar particle size distribution with a distribution constant of 0.7, and by compressing it under a pressure of 1.5 MPa for a duration of 5 min or longer.
