  1. 1. Functionalization of polymer electrolytes for electrochromic windows

    Author : İlknur Bayrak Pehlivan; Gunnar A. Niklasson; Claes-Göran Granqvist; Michel Aegerter; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrochromism; Polymer electrolytes; PEI; LiTFSI; Nanoparticles; Ionic conductivity; Ion-pair relaxation; Near-infrared absorption; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

    Abstract : Saving energy in buildings is of great importance because about 30 to 40 % of the energy in the world is used in buildings. An electrochromic window (ECW), which makes it possible to regulate the inflow of visible light and solar energy into buildings, is a promising technology providing a reduction in energy consumption in buildings along with indoor comfort.

  2. 2. Trapping Tyrosine Z : Exploring the Relay between Photochemistry and Water Oxidation in Photosystem II

    Author : Johannes Sjöholm; Stenbjörn Styring; Fikret Mamedov; A. William Rutherford; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Photosystem II; Tyrosine Z; EPR; proton-coupled electron transfer; hydrogen bond; pH;

    Abstract : Photosystem II is unique! It remains the only enzyme that can oxidize water using light as energy input. Water oxidation in photosystem II is catalyzed by the CaMn4 cluster. The electrons extracted from the CaMn4 cluster are transferred to P680+ via the tyrosine residue D1-Tyr161 (YZ). READ MORE

  3. 3. Electron impact dissociation of molecular ions at CRYRING

    Author : Ahmed Al-Khalili; Ronald A Phaneuf; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Physics; fysik;

    Abstract : In this thesis, the electron impact dissociation of molecular ions has been studied using the ion storage ring CRYRING at Manne Siegbahn Laboratory in Stockholm, Sweden. The electron impact dissociation of molecular ions occurs via many processes, which lead to different charge states of the product fragments. READ MORE

  4. 4. A new synthetic strategy for low-dimensional compounds : Lone pair cations and alkaline earth spacers

    Author : Rie Takagi Fredrickson; Mats Johnsson; Sven Lidin; Lars Kloo; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Alkaline earth; Lone pair elements; Low-dimensional compounds; Inorganic chemistry; Oorganisk kemi; oorganisk kemi; Inorganic Chemistry;

    Abstract : Complex transition metals oxyhalides containing a lone pair element, such as tellurium (IV), form an attractive research field because there is a high probability of finding new low-dimensionally arranged compounds and, particularly, a low-dimensionally arranged transition metals substructures, leading to interesting physical properties. Tellurium (IV) can drive the formation of many unusual structures because of its stereochemically active lone pair electrons, E. READ MORE

  5. 5. Signaling via Orexin Receptors : A Pharmacological Study

    Author : Tomas Holmqvist; Jyrki Kukkonen; Karl Åkerman; Gunnar Flemström; Per Svenningsson; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; orexin; receptors; calcium; cAMP; adenylyl cyclases; Fysiologi; Physiology; Fysiologi;

    Abstract : The orexin receptors are a pair of newly discovered G-protein coupled receptors which are activated by the neuropeptides orexins and play a role in sleep/vigilance, apetite/metabolism and neuroendocrine regulation. On a cellular level receptor activation results in, to name but a few effects, elevation of intracellular calcium and depolarisation. READ MORE
