  1. 1. Green Public Procurement : Legal Instruments for Promoting Environmental Interests in the United States and European Union

    Författare :Jason J. Czarnezki; Jan Darpö; Roberto Caranta; Katerina Mitkidis; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; environmental law; procurement law; green public procurement; sustainable public procurement; eco-labels; life-cycle costing; comparative law; Public Sector Directive 2014 24 EU; neoliberal regulation; sustainability; private environmental governance; public procurement; market participant exception; commerce clause; dormant commerce clause;

    Sammanfattning : While public environmental law, regulation and governance have paved the traditional road towards environmental and natural resource protection, the pathway has been expanded to include a broader orbit of interest areas and regulatory tools in an effort to achieve sustainability. Through the lens of comparative law and policy, this thesis evaluates one such expansion of environmental law—attempts to further environmental interests through public procurement in the European Union (EU) and United States (U.

    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Lignin Carbohydrates Complexes; Phenyl Glycosides; Benzyl Ethers; Benzyl and γ-esters; Universal Mild Quantitative fractionation; LCC mechanism formation; Extracellular lignin; Dehydogenation polymer; Autohydrolysis; Recalcitrance; Acetylation role; HSQC; HMBC; HSQC-TOCSY; 13C; 31P NMR; Thioacidolysis-GC; SEC; Green; Biomimetic; One-pot-lignin functionalization; Lignin platform material.; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Covalent bonds between lignin and carbohydrates, forming a matrix referred to as lignin carbohydrate complexes (LCC), remain one of the most controversial topics in wood chemistry. A key issue is whether they are formed during chemical and mechanical pretreatments of the compact wood structure or actually present in wood prior to isolation. LÄS MER

  5. 4. Stable isotope studies of contaminant and material transport in Baltic pelagic food-webs

    Författare :Carl Rolff; Nicholas J.P Owen; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; zoologi; Zoology;

    Sammanfattning : Both carbon and nitrogen appear in nature as different stable isotopes. Many natural processes affect the relative proportions of heavy and light isotopes in predictable ways. The isotopic composition of organisms and other organic materials can therefore serve as records of the processes involved in their formation. LÄS MER

  7. 5. Studying Morphology Formation and Charge Separation in Organic Solar Cells

    Författare :Yanfeng Liu; Fengling Zhang; Olle Inganäs; Jonas Bergqvist; Christoph J. Brabec; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : We are currently living in the era of automation and artificial intelligence, which requires more energy than ever before. Meanwhile, the reduction of carbon footprint is needed for keeping the environment sustainable. Exploring green energy is crucial. Solar power is one of the green energy sources. LÄS MER
