1. 21. Catalytic Functionalization of Allylic Substrates by Palladium Pincer Complexes

   Författare :Nicklas Selander; Kálmán Szabó; David Milstein; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Catalysis; Palladium; Pincer Complex; Boron; Multicomponent Reaction; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

   Sammanfattning : This thesis is based on the development of novel catalytic reactions for the synthesis and application of organometallic reagents. The main focus is directed towards organoboronate derivatives. We developed an efficient procedure for converting allylic alcohols to the corresponding allylboronates using palladium pincer complexes as catalysts. LÄS MER

3. 22. Copper and Palladium-Mediated Transformationsof Allylic and Propargylic Substrates

   Författare :Tony S. N. Zhao; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This thesis is focused on the development of new palladium and copper-mediated reactions for functionalization of alkenes and propargylic alcohol derivatives. We have developed an efficient procedure for the synthesis of allenyl and propargyl boronate from propargylic carbonates and acetates. LÄS MER

4. 23. Hollow Cathode Deposition of Thin Films

   Författare :Lars-Erik Gustavsson; Ladislav Bárdoš; Hana Baránková; Claes Nender; Uppsala universitet; []
   Nyckelord :Electronics; Hollow cathode; Hybrid plasma; PVD; TiN films; Ferromagnetic substrates; Magnetized plasma; CrN films; Elektronik;

   Sammanfattning : Thin films of metals and compounds have a very wide range of applications today. Many of the deposition methods used for the production of such films utilize plasma to support the growth the film, e.g. by the supply of energy and the enhancement of reactivity. LÄS MER

5. 24. Coated Surfaces for Inkjet-Printed Conductors

   Författare :Thomas Öhlund; Hans-Erik Nilsson; Jonas Örtegren; Jouko Peltonen; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inkjet; Nanoparticles; Paper; Flexible substrates; Sintering; Printed Electronics; Functional Printing;

   Sammanfattning : In this thesis, a number of commercially available paper substrates of various types are characterized and their characteristics related to the performance of inkjet-printed conductors using silver nanoparticle ink. The evaluated performance variables are electrical conductivity as well as the minimum achievable conductor width and the edge raggedness. LÄS MER

7. 25. Metal Films for Printed Electronics : Ink-substrate Interactions and Sintering

   Författare :Thomas Öhlund; Håkan Olin; Hans-Erik Nilsson; Mattias Andersson; Patrick Gane; Mittuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; inkjet printing; silver nanoparticles; paper; flexible substrates; sintering; printed electronics; IPL sintering; flash sintering; copper films; coatings; thin films; AgNP; conductive films; metal films;

   Sammanfattning : A new manufacturing paradigm may lower the cost and environmental impact of existing products, as well as enable completely new products. Large scale, roll-to-roll manufacturing of flexible electronics and other functionality has great potential. LÄS MER
