  1. 1. Applications of Microwave Heating of Foods

    Author : Birgitta Wäppling-Raaholt; Birgitta Raaholt; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; modelling of microwave heating; microwave-assisted HTST processing; product quality.; heat transfer; microwave heating; microwave oven; heating uniformity; microwave cavity; tubular microwave in-flow processing;

    Abstract : AbstractMicrowave heating of foods offers rapid and flexible heating both for consumer and industrial applications, with several advantages, such as reduced processing time (due to volumetric heating and reduced coming-up times (heating time required to reach the desired target temperature), selective heating, increased process flexibility and efficient heating (volumetric heating of the food does not require heating of a surrounding medium or package). However, successful installations requireknowledge in process design. READ MORE

  4. 4. Microwave power device characterization

    Author : Kristoffer Andersson; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; statistical estimation; self-heating; Silicon Carbide; Gallium Nitride; mixer; thermal resistance; wide bandgap; microwave; error-correction; small-signalmodel;

    Abstract : The first part of the thesis covers work done on device characterizationmethods. A statistical method for estimating small-signal model parametersin FET-models was proposed. A maximum likelihood estimator wasderived and the new method was compared to a standard direct extractiontechnique. READ MORE

  5. 5. Fast Chemistry by Microwave Heating : First Descriptions of Highly Enantioselective Microwave Protocols for Metal Catalysis; First Descriptions of in-situ Gas Generation for Fast Combinatorial Microwave Chemistry

    Author : Nils-Fredrik K. Kaiser; C. O.; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; Organic Pharmaceutical Chemistry; organisk farmaceutisk kemi;

    Abstract : Microwave heating was applied to different palladium-catalyzed allylic substitution reactions. The use of various nucleophiles demonstrated C-, N-, O- and S- nucleophilicity. High yields and stereopurities of the corresponding alkyls, amides, ethers and sulfones were afforded after only 30 – 120 s of heating. READ MORE
