    Abstract : In the field of sensing in general and biosensing in particular, there is a growing need for integratingminiaturised senor elements in microfluidic systems. The advantages are several, some of which being that the consumption of, often very expensive, sample material can be reduced; sampleexchange can be optimized; sensor performance in terms of detection limits can be improved and phenomena occurring on a very small, and even single-molecule, scale can be studied.

  6. 14. Structures and Properties of the Chiral Smectic C Liquid Crystal Phases Ferro- and Antiferroelectricity in Soft Matter

    Author : Jan Lagerwall; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ferroelectric liquid crystals; orientational order; smectic layer shrinkage; antiferroelectric liquid crystals; subphase suppression; confinement;

    Abstract : Liquid crystals constitute a form of soft matter possessing lower symmetry than isotropic liquids but higher symmetry than solid crystals. In smectic A and C liquid crystals, the rodlike molecules are arranged in layers and the medium has crystal order in one dimension and liquid order in the other two. READ MORE
