  2. 1. Quantitative Surface Enhanced Raman Spectroscopy

    Author : Anders Lorén; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gold colloids; internal standard; surface enhanced Raman spectroscopy; SERS; PLS; PCA; SAM; quantitative;

    Abstract : Surface enhanced Raman spectroscopy (SERS) is a very attractive technique for detection of various organic and inorganic molecules due to its sensitivity and selectivity. The surface enhancement is achieved when the molecules of interest are on or in the vicinity of a metal surface, usually gold and silver. READ MORE

  4. 2. The bentonite barrier : microstructural aspects on colloid filtration and radiation effects on bentonite colloid stability

    Author : Michael Holmboe; Mats Jonsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chemistry;

    Abstract : In many countries a multi-barrier concept in a deep geological repository is planned for final disposal of nuclear waste. Many of these different concepts, for example the Swedish KBS-3 model, include an engineered barrier consisting of compacted bentonite. READ MORE

  6. 4. Nano- and Micro-sized Molecularly Imprinted Polymer Particles on Solid Surfaces

    Author : Tripta Kamra; Synkrotronljusfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Molecularly imprinted polymers (MIPs) are artificial receptors made by imprinting template molecules in a polymer matrix followed by their removal through washing to obtain a specific and selective template cavities. This property of the MIPs have made them a very efficient material for diverse applications such as chromatography, purification, drug sensing, etc. READ MORE
