    Eine neue Synthese wichtiger Pyrrolderivate (1968)
    Weinheim : Wiley-Blackwell
    Berichte der deutschen chemischen Gesellschaft 101 (1968), S. 240-243

    Notes: Es wird eine einfache Darstellung für 2.3-Dimethyl-pyrrol-propionsäure-(4)-carbonsäure-(5)-diäthylester (3) und für 2-Methyl-pyrrol-essigsäure-(3)-propionsäure-(4)-carbonsäure-(5)- triäthylester (4) beschrieben. Da man aus 4 Porphobilinogen gewinnen kann, ist damit auch die Synthese dieses Naturstoffs wesentlich vereinfacht worden.

    A Completely New Type of Actuator -or- This Ain't Your Grandfather's Internal Combustion Engine (2010)
    In:  CASI
    Details
    Publication Date: 2018-06-11
    Description: A completely new type of actuator - one that is proposed for use in a variety of environments from sea to land to air to space - has been designed, patented, built, and tested. The actuator is loosely based on the principle of the internal combustion engine, except that it is a completely closed system, only requiring electrical input, and the working fuel is water. This paper outlines the theory behind the electrolysis- and ignition-based cycle upon which the actuator operates and describes the performance capability test apparatus and results for the actuator. A mechanism application that harnessed the unit s power to twist a scaled rotor blade is also highlighted.
