  1. 16. Utilization of cellulosic biomass towards sustainable chemicals and novel biomaterials

    Författare :Jiayi Yang; Magnus Norgren; Håkan Edlund; Fardim Pedro; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : It is predicted by the United Nations that by year 2030 the world will need at least 50 percent more food, 45 percent more energy and 30 percent more water. The emissions of carbon dioxide from combustion of fossil fuels and waste are also increasing. LÄS MER

  3. 17. Development of Constituents for Multi-functional Composites Reinforced with Cellulosic Fibers

    Författare :Zainab Al-Maqdasi; Roberts Joffe; Nazanin Emami; Liva Pupure; Yvonne Aitomäki; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose fibers; multi-functional; composites; nano-reinforcement; thermoplastics; development; Polymeric Composite Materials; Polymera kompositmaterial;

    Sammanfattning : Bio-basedcomposites are being increasingly used in applications where weight saving,and environmental friendliness is as important as structural performance. Obviously, bio-based materials have their limitations regarding durability and stability of the properties,but their potential in use for advanced applications can be expanded if they were functionalized and considered beyond their structural performance.

  5. 19. Insights into the metabolism of Clostridium thermocellum for cellulosic ethanol production

    Författare :Johannes Yayo; Antonius J. A. van Maris; Richard Sparling; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Clostridium thermocellum; ethanol; glucose; fructose; amino acids; pyrophosphate; chaotropicity; thermodynamic driving force; laboratory evolution; chemostats; metabolic engineering; Biotechnology; Bioteknologi;

    Sammanfattning : The societal goal of reaching net-zero CO2 emissions requires development of integrated biorefineries to produce biomass-derived fuels and chemicals. For sustainable second-generation bioethanol production, consolidated bioprocessing with the thermophile Clostridium thermocellum is regarded as a promising concept in view of the microorganism’s native ability to efficiently degrade plant cell wall material.

  7. 20. Filtration of Cellulosic material - the impact of ionic strength and electric field

    Författare :Anna Lidén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electro-assisted; microfibrillated cellulose; ionic strength; microcrystalline cellulose; dead-end filtration;

    Sammanfattning : It is crucial that dewatering technology is considered if an economically feasible production of cellulosic materials is to be achieved. Cellulosic materials are often produced in dilute streams and therefore require great amounts of water to be removed to allow for reasonable transportation costs and/or further modifications. LÄS MER
