  2. 1. Decision Support for Energy Transition : Application of Multi-criteria Decision Making on Danish Residential Heating

    Author : Qianyun Wen; Yang Liu; Olof Hjelm; Xiufeng Liu; Pascale Zarate; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : With the increasing awareness of the impact of climate change, there has been more intention to reduce greenhouse gas emissions and achieve carbon neutrality targets. However, as one essential element for human well-being, residential heating remains a major contributor to global greenhouse gas emissions. READ MORE

  4. 2. Design, Fabrication, and Characterization of Nano-Photonic Components Based on Silicon and Plasmonic Material

    Author : Liu Liu; Lars Thylén; Roe Baets; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nano-photonics; finite-difference time-domain method; finite-difference mode solver; amorphous silicon; silicon nanowire; arrayed waveguide grating; photonic crystal; Photonics; Fotonik;

    Abstract : Size reduction is a key issue in the development of contemporary integrated photonics. This thesis is mainly devoted to study some integrated photonic components in sub-wavelength or nanometric scales, both theoretically and experimentally. READ MORE

    Abstract : YTTERBY, a small village very close to Stockholm where I live, is the place in the world which has lent its name to the largest number of elements in the periodic table, namely four - YTTRIUM, YTTERBIUM, ERBIUM and TERBIUM. Three more lanthanide elements were discovered from the now empty quarry located in this village. READ MORE

  6. 4. Theoretical Studies of Natural Gas Hydrates and H-bonded Clusters and Crystals

    Author : Yuan Liu; Lars Ojamäe; Per-Olov Käll; Ben Slater; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this thesis H-bonded systems (natural gas hydrates, water clusters, and crystal ice) are studied by density functional theory (DFT) computations.Natural gas hydrates (NGHs) play an important role in energy and environmental fields: NGHs are considered as a promising backup energy resource in the near-future due to their tremendous carbon content; improper exploration of NGHs could induce geological disasters and aggravate the greenhouse effect.

  7. 5. Light-Emitting Electrochemical Transistors

    Author : Jiang Liu; Magnus Berggren; Isak Engquist; Qibing Pei; Linköpings universitet; []
    Keywords : ;

    Abstract : Since the discovery of conductive polymers in 1977, the implementation of organic conjugated materials in electronic applications has been of great interest in both industry and academia. The goal of organic electronics is to realize large-area, inexpensive and mechanically-flexible electronic applications. READ MORE
