3. 2. Ruthenium-catalyzed redox reactions and lipase-catalyzed asymmetric transformations of alcohols

   Författare :Michaela Edin; Jan-E. Bäckvall; Manfred T. Reetz; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ruthenium; lipase; catalysis; alcohols; diols; Chemistry; Kemi;

   Sammanfattning : The major part of this thesis describes the synthesis of enantiopure alcohols and diols by combining ruthenium-catalyzed redox reactions that lead to racemization or epimerization and lipase-catalyzed asymmetric trans-formations in one-pot.A mechanistic study of the unexpected facile formation of meso-diacetate products found in enzyme-catalyzed acetylations of alkanediols with Candida antarctica lipase B (CALB) was first performed.

4. 3. From Peak to Peak: Exploring Electron Hopping and Mass Transport in Metal-Organic Frameworks

   Författare :Ashleigh T. Castner; Sascha Ott; Deanna M. D'Alessandro; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; charge transport; mass transport; metal-organic frameworks; electrocatalytic materials; electrochemistry; Kemi; Chemistry;

   Sammanfattning : Incorporating molecular electrocatalysts into solid support structures combines the best of two worlds: their molecular nature allows precise structural tunability for selective and efficient conversion of small molecule substrates, while their structural integrity is greatly improved by the heterogeneous support matrix to allow for long-term stability and potentially industrial-scale applications. Metal-organic frameworks (MOFs) represent a potential class of materials to act as viable support scaffolds for hosting molecular catalysts for sustainable energy conversion, exhibiting well-ordered porous structures that can support high loading densities of catalyst species.

7. 5. Vid existensens gräns : Etiskt vårdande och professionellt ansvar vid hjärtstopp utanför sjukhus

   Författare :Anders Bremer; Lars Sandman; Karin Dahlberg; Anna T. Höglund; Högskolan i Borås; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; emergency medical services; ethical competence; ethics; out-of hospital cardiac arrest; lifeworld; phenomenology; professional responsibility; sudden cardiac death; Vårdvetenskap; Caring Science; Integrated Caring Science;

   Sammanfattning : Aim: To describe and interpret patients’, family members’ and ambulance personnel’s experiences with regard to survival, attendance, and caring at cardiac arrests and deaths, and to analyze ethical conflicts that arise in relation to families and how the personnel’s ethical competence can affect caring and the ability to handle ethical problems.Method: The three interview studies were guided by a reflective lifeworld approach grounded in phenomenology and analyzed by searching for the essence of the phenomenon in two studies and by attaining a main interpretation in one study.
