  1. 1. Biocomposites Based on Core-Shell Cellulose Nanofibers : Preparation, Structure, and Properties

    Författare :Kasinee Prakobna; Lars Berglund; David Plackett; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biocomposites; cellulose nanofibers; polysaccharides; holocellulose; nanostructure; dispersion; mechanical properties; hygromechanical properties; moisture stability; film; porous material; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Cellulose nanofibers (CNFs) are of interest as load-bearing components for polymer matrix nanocomposites. A wide range of nanostructured materials including nanopaper/films, foams, aerogels, and hydrogels can be prepared from CNFs. The material performance can be fine-tuned when CNFs are combined with different polymer matrices. LÄS MER

  3. 2. Study on the structure and properties of xylan extracted from eucalyptus, sugarcane bagasse and sugarcane straw

    Författare :Danila Carvalho; Mikael Lindström; Åsa Emmer; Sverker Danielsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Lignocellulosic biomasses are an important source of chemical components such as cellulose, lignin and hemicelluloses, and can be used for a variety of purposes in both the pulp and paper and chemical conversion industries. Xylan, the main hemicellulose found in hardwood and grass plants, plays an important role during the pulping/pretreatment process reactions, including those used in 2nd generation bioethanol production.

  4. 3. Development and Application of Methods based on DOAS and FTIR Absorption Spectroscopy for Atmospheric Research

    Författare :Bo Galle; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; open-path; nitrous oxide; DOAS; long-path absorption; landfill; methane; climate gases; ozone depletion; biogenic emissions; fugitive emissions; FTIR; ammonia;

    Sammanfattning : Over the past decades concern about the environmental impact on our atmosphere from human activities has been constantly increasing. From the recognition of local industrial pollution in the first part of this century, over regional scale problems related to urbanisation and growth of traffic systems to global environmental problems such as climate change and stratospheric ozone depletion.

  5. 4. Application of chemical oxidation processes for the removal of pharmaceuticals in biologically treated wastewater

    Författare :Gerly Hey; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The discharge of effluents from wastewater treatment plants (WWTPs) is considered to be the major source of residual pharmaceuticals frequently found in aquatic environments. The complex nature of such compounds tends to make conventional biological treatments aimed at their removal ineffective. LÄS MER
