1. 16. Theoretical Routes for c-BN Thin Film Growth

   Författare :Johan Karlsson; Karin Larsson; Sven Ulrich; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cubic boron nitride; chemical vapor deposition; density functional theory; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

   Sammanfattning : Cubic boron nitride (c-BN) has been in focus for several years due to its interesting properties. The possibility for large area chemical vapor deposition (CVD) is a requirement for the realization of these different properties in various applications. Unfortunately, there are at present severe problems in the CVD growth of c-BN. LÄS MER

   Sammanfattning : The potentially most important challenges today are related to energy and the environment. New materials and methods are needed in order to, in a sustainable way, convert and store energy, reduce pollution, and clean the air and water from contaminations. LÄS MER

4. 18. Insights into Electrochemical Energy Storage by use of Nanostructured Electrodes

   Författare :David Rehnlund; Leif Nyholm; Kristina Edström; Fredrik Björefors; Emanuel Peled; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi med inriktning mot oorganisk kemi; Chemistry with specialization in Inorganic Chemistry;

   Sammanfattning : Template-assisted electrodeposition is a powerful technique for fabricating complex nanostructured electrodes. Through the use of pulsed-electrodeposition nanostructured electrodes of Al, Cu and Sn have been realised and subsequently coated electrochemically with V2O5, MnxO, Li, Cu2O and a polymer electrolyte.
