  1. 21. Valorization of Kraft Lignin by Fractionation and Chemical Modifications for Different Applications

    Författare :Selda Aminzadeh; Mikael Lindström; Hasan Jameel; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lignin Valorization- LignoBoost Lignin-Clean Flow Black Lignin- Characterization-Chemical modifications-Fractionation-applications; Chemical Engineering; Kemiteknik;

    Sammanfattning : AbstractLignin is one of the most abundant biopolymers. Approximately 70 million tons of technical lignin is generated annually, but only little is used for products other than energy. The complexity of lignin hinders full utilization in high-value products and materials. LÄS MER

  3. 22. Enhancing the stability of probiotics: Freeze-drying and encapsulation

    Författare :Shuai Bai; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; freeze-drying; lyophilization; L.ruteri; Probiotics; Lyoprotectant; Structure; Encapsulating material; Pore size; Material thickness; SEM; Tomography; Storage stability; Amorphous sugars; Glass transition temperature; DSC;

    Sammanfattning : This research dives into the intricate world of freeze-drying, an essential process in pharmaceutical and probiotic industries, to better understand the factors affecting probiotic stability during storage. The process of freeze-drying and the composition of freeze-dried products significantly affect the stability of probiotics, yet factors such as the material’s encapsulation properties remain relatively unexplored, demanding further research.

    Sammanfattning : This thesis is about the social body in sociology, represented by the classical sociologist Max Weber. Traditional sociology has not taken the body into account. The body has been considered to belong to the realm of the natural sciences. Sociology has seen the body merely as an instrument or a tool for social action. LÄS MER

    Sammanfattning : Climate change and densification of cities are two major global challenges. Inthe building and construction industry, there are great expectations that tall timberbuildings will constitute one of the most sustainable solutions. First, verticalurban growth is energy and resource-efficient. LÄS MER
