  2. 21. Assessing the sustainability of bioethanol production in Nepal

    Author : Dilip Khatiwada; Semida Silveira; Andrew Martin; Björn Karlsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Bioethanol; sustainability; life cycle assessment; net energy values; greenhouse gas GHG balances; sustainable development; least developed countries LDCs ; Nepal; Mechanical and thermal engineering; Mekanisk och termisk energiteknik; Climatology; Klimatologi;

    Abstract : Access to modern energy services derived from renewable sources is a prerequisite, not only for economic growth, rural development and sustainable development, but also for energy security and climate change mitigation. The least developed countries (LDCs) primarily use traditional biomass and have little access to commercial energy sources. READ MORE

  4. 22. The use of air pollution control residues in landfill covers and for soil stabilization

    Author : Igor Travar; Richard Beaven; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

    Abstract : About 66% of all heat energy generated in Sweden originates from the incineration of municipal solid waste and biofuels such as wood, cardboard and peat. In addition to heat energy, incinerators generate about 1.7 Mt of ashes each year, of which 500 000 t are air pollution control (APC) residues. READ MORE

  5. 23. Polysaccharides from red and green seaweed : Extraction, characterisation and applications

    Author : Niklas Wahlström; Ulrica Edlund; Fredrik Gröndahl; Federica Chiellini; KTH; []
    Keywords : biorefinery; seaweed; macroalgae; Ulva; Porphyra; ulvan; porphyran; cellulose; gelatin; hydrogel; heavy metal; methylene blue; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Cultivation of seaweed has been conducted for centuries in Asia, but is largely undeveloped in Sweden even though there is potential for this industry. Seaweed offers benefits compared with land-based biomass cultivation. READ MORE

  6. 24. Pre-harvest factors affecting quality and shelf-life in raspberries and blackberries (Rubus spp. L.)

    Author : Liaqat Ali; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Fruit including berries have been demonstrated to exhibit a broad spectrum of benefits including protection against cardiovascular, neurological, and lung diseases, as well as having antioxidant, antimicrobial, anti-inflammatory, anti- diabetic and anti-aging properties. These protective effects are reported to be due to their high content of bioactive compounds, such as vitamin C, vitamin E, phenolic acids, ellagitannins, flavonoids and carotenoids. READ MORE

  7. 25. Probing Atomic Scale Structure and Catalytic Properties of Cobalt Oxide Model Catalysts

    Author : Alif Arman; Synkrotronljusfysik; []
    Keywords : catalysis; model systems; Co3O4 111 ; Co3O4 100 ; CoO 111 ; X-ray photoelectron spectroscopy; Scanning tunneling microscopy; Fysicumarkivet A:2017:Arman;

    Abstract : Cobalt oxides are known to be active catalysts for a number of chemical reactions, but very little is known about the atomic scale processesresponsible for the activity. The research presented in this thesis is focused on obtaining an atomic scale understanding of the chemistry of wellcharacterizedcobalt oxide model catalyst surfaces consisting of pristine and defective CoO and Co3O4 thin films with the (111) and (100)terminations supported by Ag(100), Ir(100), and Au(111) single crystal surfaces.
