Abstract:
System for the electrochemical cleavage of compounds which includes a mediator which has no metals or heavy metals and at least two electrodes for the electrochemical activation of the mediator.
Abstract:
Process for the preparation of heteroaryl aldehydes or heteroaryl ketones by reaction with heteroarylmethanols with the aid of a mediator and an oxidant, wherein the mediator is selected from the group of the aliphatic, cycloaliphatic, heterocyclic or aromatic NO, and NOH containing compounds.
Abstract:
In processes of holography using bacteriorhodopsin-based recording media, it is essential to design the signal-to-noise ratio to be as favorable as possible. This is achieved by recording the hologram using circularly polarized light and reconstructing the hologram by using linearly polarized light, specific beam components being selected as a function of polarization in the beam path of the reconstructed hologram. The process is suitable both for purely holographic applications and also for other processes which include one or more intermediate or partial steps involving holography.
Abstract:
A chemically sensitive transducer for selectively determining a chemical property of a fluid and providing a measurement signal to an amplifying circuit. The transducer has a measuring electrode coupled to the amplifying circuit and provides a measurement signal to the amplifying circuit. A membrance covers the measuring electrode, this membrane being sensitive to a specified chemical property. A carrier plate, with first and second sides, has the measuring electrode arranged on its first side and the amplifying circuit on its second side. The carrier plate has a conductor extending between the first and second sides which electrically couples the measuring electrode and the amplifying circuit.
