Cutting Tests of the Outer Layer of Material Using Onion as an Example.

This paper describes experimental research on cutting the outer layer of onions in the machine peeling process. The authors' own globally innovative modular machine construction was used for this purpose. The onion peeling machine was constructed on a real scale.

Collective and local molecular dynamics in the lyotropic mesophases of decylammonium chloride: 1H and 2H NMR study.

The collective and individual dynamics of decylammonium chloride (DACl) molecules in water environment were investigated as a function of surfactant concentration and temperature. In the presence of water the DACl forms a variety of self-assembled structures, ranging from isotropic micellar systems to lyotropic liquid crystalline phases of hexagonal, nematic, and lamellar types. In order to characterize the complex molecular dynamics that occur in the DACl-water system, we applied 1H and 2H NMR techniques that cover the whole frequency range between 1 kHz and 30 MHz.
