  1. 1. Signal Separation - II

    Författare :Ulf Lindgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; local convergence; mutual information; chi square test; signal enhancement; parameter identifiability; source separation; signal separation; algorithms;

    Sammanfattning : Signal separation is a signal processing technique which enables the separation of superimposed signals. There are several practical situations were signal separation can be used, for example in noise reduction for cellular phones subject to background noise. LÄS MER

  5. 4. Enantiomeric separation by capillary electrophoresis : With special emphasis on the partial filling technique

    Författare :Ahmad Amini; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; analytisk farmaceutisk kemi; Analytical Pharmaceutical Chemistry;

    Sammanfattning : Capillary electrophoresis as a powerful separation technique was employed for resolution of racemic drugs. Taurodeoxycholate (TDC), different cyclodextrins and α1- acid glycoprotein (AGP) were dissolved in the background electrolyte at low pH (3.0 to 4.0 ) as chiral selectors. LÄS MER

  7. 5. Cellulose Nanofibril-based Hybrid Materials : Eco-friendly design towards separation and packaging applications

    Författare :Luis Valencia; Aji Mathew; Olli Ikkala; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cellulose nanofibrils; hybrid materials; membranes; aerogels; separation; food packaging; Materials Chemistry; materialkemi;

    Sammanfattning : Nanocellulose has been lately considered as the “Holy-Grail” in the design of sustainable materials due to its bio-origin and an unprecedented combination of prominent features, including good mechanical properties, anisotropy and versatile surface chemistry. In addition, nanocellulose in the form of cellulose nanofibrils, can adopt variable structures and morphologies depending on the processing technique, such as aerogels, films and monoliths. LÄS MER
