  1. 21. Selective laser sintering for 3D printing of medications

    Författare :Evgenii Tikhomirov; Jonas Lindh; Julian Quodbach; Maria Strömme; Ocean Cheung; Jarkko Ketolainen; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; 3D printing; Selective laser sintering; Personalized medicines; Drug manufacturing; Teknisk fysik med inriktning mot nanoteknologi och funktionella material; Engineering Science with specialization in Nanotechnology and Functional Materials;

    Sammanfattning : Suboptimal treatment caused by inaccurate dosing of prescribed medications is a challenging issue for the pharmaceutical industry. As a result, certain groups of patients, especially pediatric patients, may suffer from a lack of specific dosage forms, leading to potential side effects. LÄS MER

  3. 22. SiGeC Heterojunction Bipolar Transistors

    Författare :Erdal Suvar; KTH; []
    Nyckelord :Silicon-Germanium-Carbon SiGeC ; Heterojunction bipolar transistor HBT ; chemical vapor deposition CVD ; selective epitaxy; non-selective epitaxy; collector design; high-frequency measurement; dopant segregation; thermal stability;

    Sammanfattning : Heterojunction bipolar transistors (HBT) based on SiGeC havebeen investigated. Two high-frequency architectures have beendesigned, fabricated and characterized. Different collectordesigns were applied either by using selective epitaxial growthdoped with phosphorous or by non-selective epitaxial growthdoped with arsenic. LÄS MER

    Författare :Angela van der Werf; Nicklas Selander; Gary A. Molander; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; alkynyl enones; catalysis; copper; halogenation; heterocycles; nitrosoarenes; perfluoroalkylation; trifluoromethylation; organisk kemi; Organic Chemistry;

    Sammanfattning : The nitrogen atom plays a unique role in organic chemistry. It is abundantly found in organic materials and is responsible for the activity of many biologically relevant compounds. LÄS MER

  5. 24. The Role of Cyclooxygenase-2 in Models of Epilepsy and Traumatic Brain Injury : Effects of Selective Cyclooxygenase-2 Inhibitors

    Författare :Tina Kunz; Tadeusz Wieloch; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Controlled cortical contusion injury; fluid percussion injury; limbic seizures; nuclear factor-kappa B; prostaglandin metabolism; TUNEL staining; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; farmaceutisk farmakologi; Pharmaceutical Pharmacology;

    Sammanfattning : Cyclooxygenase-2 (COX-2) catalyses prostaglandin synthesis from arachidonic acid during inflammation. COX-2 is expressed in the normal brain and is induced in neurological disorders. There is evidence that COX-2 is involved in secondary events leading to cell death in the brain. LÄS MER

  7. 25. Spectrally Selective Solar Absorbing Coatings Prepared by dc Magnetron Sputtering

    Författare :Shuxi Zhao; Ewa Wäckelgård; Carl-Gustaf Ribbing; Volker Wittwer; Uppsala universitet; []
    Nyckelord :Materials science; spectrally selective surface; solar energy; magnetron sputtering; thin film; Materialvetenskap;

    Sammanfattning : Spectrally selective solar absorber using composite Ni-NiO as coating materials was studied. Samples were prepared by dc magnetron sputtering unit named Rulle, which is a miniature copy of an industrial roll-coater unit. LÄS MER
