1. 11. Flexible and Cellulose-based Organic Electronics

   Författare :Jesper Edberg; Magnus Berggren; Isak Engquist; Leif Nyholm; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic electronics; conductive polymers; nanocellulose; nanofibrillated cellulose; composite materials; paper electronics; flexible electronics;

   Sammanfattning : Organic electronics is the study of organic materials with electronic functionality and the applications of such materials. In the 1970s, the discovery that polymers can be made electrically conductive led to an explosion within this field which has continued to grow year by year. LÄS MER

3. 12. Dynamic and quasi-stationary electrochromic response of amorphous tungsten oxide thin films : In situ combined electrochemical and optical measurements during lithium intercalation

   Författare :Edgar Alonso Rojas González; Gunnar Niklasson; Aline Rougier; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electrochromism; Optical absorption; Amorphous materials; Tungsten oxide; Electrochemical impedance spectroscopy; Color impedance spectroscopy; Intercalation; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

   Sammanfattning : Electrochromic (EC) materials can adjust their optical properties, reversibly, by means of an external electrical stimulus. They have relevant technological applications; for example, energy-efficient smart windows, which can adapt dynamically—according to the given environmental conditions—to control the heat and visible light fluxes between the interior and exterior of a building.

4. 13. Atomic short-range order, optical and electronic properties of amorphous transition metal oxides : An experimental and theoretical study of amorphous titanium aTiO2 and tungsten aWO3 solid thin-film oxides

   Författare :Carlos A Triana; Tomas Edvinsson; Petter Persson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; X-ray-Absorption; Reverse Monte Carlo; Molecular dynamics; Electronic structure;

   Sammanfattning : Amorphous transition metal oxides [aTMOs], have emerged as innovative functional materials for wide-ranging electronic, optical and energy-related applications. However, no systematic and broadly applicable method exists to assess their atomic-scale correlations, and since the optical and electronic processes are local structure-dependent, still there are not well-stablished mechanisms that suitably explain the physical properties of aTMOs.

5. 14. Deterministic Silicon Pillar Assemblies and their Photonic Applications

   Författare :Bikash Dev Choudhury; Anand Srinivasan; Harish Bhaskaran; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanopillar; nanowires; nanophotonics; nanofabrication; silicon; photovoltaics; second-harmonic generation; top-down approach; colloidal lithography; color filter; biosensor; Fysik; Physics; Teknisk materialvetenskap; Materials Science and Engineering;

   Sammanfattning : It is of paramount importance to our society that the environment, life style, science and amusement flourish together in a balanced way. Some trends in this direction are the increased utilization of renewable energy, like solar photovoltaics; better health care products, for example advanced biosensors; high definition TV or high resolution cameras; and novel scientific tools for better understanding of scientific observations.

7. 15. Massive MIMO: Prototyping, Proof-of-Concept and Implementation

   Författare :Steffen Malkowsky; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Massive MIMO; Testbed Design; Prototyping; ASIP; Processor;

   Sammanfattning : Wireless communication is evolving rapidly with ever more connected devicesand significantly increasing data rates. Since the invention of the smartphoneand the mass introduction of mobile apps, users demand more andmore traffic to stream music, watch high-definition video or to simply browsethe internet. LÄS MER
