  1. 21. Peasant proudction and limits to labour Thyolo and Mzimba Districts in Malawi, mid-1930s to late-1970s

    Author : Erik Green; Ekonomisk-historiska institutionen; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social and economic history; production; peasant; Malawi; Africa; accumulation; agriculture; Ekonomisk och social historia;

    Abstract : The persistence of a low productive peasant sector in sub-Saharan Africa is one of the enigmas of development research. This study approaches the question from a historical perspective by analysing the paths of agrarian change in two contrasting cases in Malawi from the mid-1930s to the late 1970s. READ MORE

  2. 22. N-Heterocyclic Carbene Catalysis in Organic Synthesis - A Green Chemistry Approach

    Author : Linda Ta; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; aerobic oxidation; ionic liquid; sustainability; NHC catalysis; oxidative NHC catalysis; green chemistry; OTHO; Organocatalysis;

    Abstract : The twelve principles of green chemistry were created as a response to the multiple environmental issues caused by the release of waste from the chemical industry. The principles acts as a guide in the development of sustainable chemical processes for the syntheses of important molecules needed to sustain our living standards. READ MORE

  3. 23. Electrocatalyst materials for low-temperature hydrogen fuel cells

    Author : Gerard Montserrat Siso; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Catalyst; Alloys.; Oxygen Reduction; Nanofabrication; Electrode; Fuel Cell; PEMFC; Hydrogen Oxidation; Model System; Thin Film; AEMFC;

    Abstract : Fuel cells have emerged as an alternative to satisfy the need of energy systems with net-zero emissions. Although fuel cells date back to the 1800s, it is only during the last decades that research and development has enabled true commercialization. READ MORE

  4. 24. Nanocellulose and Metal-Organic Framework-Based Composites : Synthesis, Characterization, and Applications

    Author : Shengyang Zhou; Chao Xu; Maria Strömme; Lars Wågberg; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanocellulose; Metal–organic frameworks; Nanocomposites; Interfacial synthesis; Porous materials; Energy storage; Water purification;

    Abstract : Nanocellulose is one of the most promising of the green materials available for use in a sustainable economy because of its natural abundance and renewability. Compared to petroleum‒derived synthetic polymers, nanocellulose has many unparalleled advantages such as its unique nanofibrous structure, high thermal stability, mechanical flexibility, rich surface chemistry, biocompatibility, and biodegradability.
