    University essay from Göteborgs universitet / Institutionen för fysik

    Author : Giannis Kostaras; [2021-01-26]
    Keywords : ;

    Abstract : Molecular solar thermal storage materials are proposed as a clean, renewable energysolution for a world with ever increasing energy needs. Norbornadiene is anorganic compound suitable for molecular solar thermal storage systems. READ MORE

  2. 2. Corrosion protection of aluminum coated with a polymer matrix in presence and absence of conductive polymer

    University essay from KTH/Ytbehandlingsteknik

    Author : Mohamed Hassan Abdi; [2021]
    Keywords : Corrosion protection; Barrier coating; Conductive polymer; Electrochemical impedance spectroscopy; Atomic force microscopy; Korrosionsskydd; Barriär beläggning; Ledande polymer; Elektrokemisk impedans spektroskopi; Atomkraftmikroskopi;

    Abstract : Aluminium och aluminiumlegeringar har ganska bra korrosionsbeständighet, men dessa material kan fortfarande korrodera. Metallkorrosion är aldrig önskvärt och det kan leda till katastrofala resultat i olika branscher och applikationer. READ MORE

  3. 3. Synthesis of Graphene - Carbon Nanotube Hybrid Structures

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Aniruddha Paul; [2021]
    Keywords : Graphene; Carbon nanotubes; Graphene-CNT hybrid structures; Chemical Vapor Deposition CVD ; Grafen; Kolnanorör; Grafen-CNT-hybridstrukturer; Kemisk ångdeposition CVD ;

    Abstract : Graphene and Carbon nanotubes (CNTs) have been researched for more than a decade due to their extraordinary properties and advantages towards applications like electronics, structural re-enforcements, thermal management and energy storage. Graphene-CNT hybrid structures have been predicted to further enhance the exceptional properties and overcome some of the shortcomings of the individual materials. READ MORE

  4. 4. X-ray Photoelectron Spectroscopy on Clusters: From Water Clusters to Metal & Metal-Oxide Nanoparticles

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Keywords : Nanoscience; Nanoparticles; Clusters; Synchrotron Radiation; Water Particles; Silver Particles; Silver Oxides; Ethylene Epoxidation; Radiotherapy; PES; XPS; Lund University; FlexPES; MAX IV; Physics and Astronomy;

    Abstract : In the present work, two experimental setups aimed at the production of (1) water clusters and (2) metal-oxide nanoparticles were assembled and commissioned. The experiments on the cluster/nanoparticle beams were set up and performed at the FlexPES beamline of the MAX-IV synchrotron facility. READ MORE

  5. 5. Study of the vibronic mixing in chlorophylls with multidimensional spectroscopy

    University essay from Lunds universitet/Kemiska institutionen

    Author : Ignacio Martínez Casasús; [2021]
    Keywords : Two-dimensional spectroscopy; Ultrafast spectroscopy; Chlorophyll a; Chlorophylls; Photosynthesis; Light harvesting; Vibronic mixing; Quantum coherence; Chemical physics; Chemistry;

    Abstract : Chlorophylls comprise one of the most important families of molecules for the photosynthetic process. Chlorophyll-like molecules have been classically interpreted under the Gouterman model, being thought to feature two independent transitions, Qy(S1) and Qx(S2). READ MORE
