1. 1. Electronic Structure of π-Conjugated Materials and Their Effect on Organic Photovoltaics

   Författare :Chuanfei Wang; Mats Fahlman; Xianjie Liu; Ergang Wang; Zong-Xiang Xu; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The great tunability of structure and electronic properties of π-conjugated organic molecules/polymers combined with other advantages such as light weight and flexibility etc., have made organic-based electronics the focus of an exciting still-growing field of physics and chemistry for more than half a century.

3. 2. Performance Aspects in Millimeter-Wave Wireless  Networks

   Författare :Cristian Tatino; Di Yuan; Nikolaos Pappas; Ilaria Malanchini; Ewe Lutz; Marian Codreanu; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The ever-growing data rate and comunications demand pose more challenges for the upcoming generations of mobile communications, i.e., fifth generation (5G) and beyond. To deal with these challenges, several solutions can be deployed, e. LÄS MER

4. 3. Creep aspects of softwood from the cell-wall level to structures

   Författare :Rhodel Bengtsson; E. Kristofer Gamstedt; Mahmoud Mousavi; Reza Afshar; Falk Wittel; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Creep; Solid Mechanics; Wooden Materials; Linear Viscoelasticity; Experiments; Materialvetenskap; Materials Science;

   Sammanfattning : This thesis addresses the intricate mechanical behaviour of natural materials, with a particular focus on wood. Despite millennia of use, understanding the mechanical behaviour of wood materials remains challenging due to their complex microstructures. LÄS MER

5. 4. From meteors to space safety : dynamical models and radar measurements of space objects

   Författare :Daniel Kastinen; Johan Kero; Asta Pellinen-Wannberg; Mats Holmström; Detlef Koschny; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Meteors; meteor shower; atmosphere; meteoroids; meteoroid stream; small-body dynamics; solar system; comets; asteroids; near-Earth objects; space safety; space debris; radar; MU; EISCAT;

   Sammanfattning : Every day the Earth's atmosphere is bombarded by 10-200 metric tons of dust-sized particles and larger pieces of material from space called meteoroids. Dust and meteoroids come from parent bodies such as comets and asteroids, which are remnants from the formation of the solar system. LÄS MER

7. 5. Nano- and mesoscale morphology evolution of metal films on weakly-interacting surfaces

   Författare :Bo Lü; Kostas Sarakinos; Peter Münger; Thomas Michely; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Thin films are structures consisting of one or several nanoscale atomic layers of material that are used to either functionalize a surface or constitute components in more complex devices. Many properties of a film are closely related to its microstructure, which allows films to be tailored to meet specific technological requirements. LÄS MER
