  2. 11. Advancing Bioenergy in Europe: Exploring bioenergy systems and socio-political issues

    Author : Kes McCormick; Internationella miljöinstitutet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Bioenergy; Sustainable Development; Political and administrative sciences; Biomass; Renewable Energy; förvaltningskunskap; Statsvetenskap; Energy Policy; Social sciences; Samhällsvetenskaper;

    Abstract : This thesis concentrates on bioenergy (or biomass utilised for heat, electricity and fuels for transport) as a renewable energy with significant potentials and options. Biomass can be considered as 'stored' solar energy because the process of photosynthesis 'captures' energy from the sun in growing plants. READ MORE

  4. 12. Stress responses of Arabidopsis plants with a varying level of non-photochemical quenching

    Author : Hanna Johansson Jänkänpää; Stefan Jansson; Barbara Demmig-Adams; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis; NPQ; PsbS; photosynthesis; field experiment; metabolomics; Physiological Botany; fysiologisk botanik; molekylärbiologi; Molecular Biology;

    Abstract : When light energy input exceeds the capacity for photosynthesis the plant need to dissipate the excess energy and this is done through non-photo-chemical quenching (NPQ). Photochemical quenching (photosynthesis), NPQ and fluorescence are three alternative faiths of excited chlorophylls. PsbS associates to photosystem II and is involved in NPQ. READ MORE

  5. 13. Surface Engineering of BiVO4-based Photoelectrochemical Cells for Water Splitting

    Author : Qijun Meng; Licheng Sun; Jae Sung Lee; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; photoelectrochemical water splitting; photoanodes; bismuth vanadate; surface engineering; Kemi; Chemistry;

    Abstract : Photoelectrochemical (PEC) water splitting is a promising technology for converting solar energy into green hydrogen. The development of highly efficient, robust and cost-effective photoanodes has been established to be of essential importance for PEC water oxidation. READ MORE

  6. 14. Spectroscopy on the Dot : Photoelectron Spectroscopy and Time-Resolved Studies of Lead Sulfide Quantum Dots for Solar Cells

    Author : Tamara Sloboda; Ute B. Cappel; Andreas Lindblad; Lars Kloo; Regan Wilks; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry;

    Abstract : Renewable energy is an important topic as global energy consumption continues to rise. Because the sun emits an enormous amount of energy, solar energy is a promising source. However, most of the commercial solar cell technology is manufactured in an energy demanding process and there is a need for new, easily processed materials. READ MORE

  7. 15. Composite Nanostructured Materials for Renewable Energy Applications

    Author : Elfatih Mohammed Mustafa; Omer Nur; Magnus Willander; Malik Maaza; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar energy; Photocatalysis; Solar cells; Nanostructured materials; ZnO; CuO; Ta2O5; GaAs;

    Abstract : Diverse sources of energy are becoming increasingly significant in today's world. The most common source of energy today is fossil fuels, such as coal, oil, and gas. While this energy source has many advantages, it also comes with many problems. READ MORE
