  1. 1. Engineering of Native Cellulose Structure for Pharmaceutical Applications : Influence of Cellulose Crystallinity Index, Surface Area and Pore Volume on Sorption Phenomena

    Author : Albert Mihranyan; Ragnar Ek; Maria Strømme; Hans Leuenberger; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; microcrystalline cellulose; Cladophora sp. algae; crystallinity index; surface area and pore volume; fractals; stability; Galenisk farmaci; Pharmaceutics; Galenisk farmaci;

    Abstract : Cellulose powders from various sources were manufactured and characterized to investigate the influence of their crystallinity index, surface area, and pore volume on sorption phenomena and the relevant pharmaceutical functionality. The influence of the cellulose crystallinity index on moisture sorption was important at low and intermediate relative humidities. READ MORE

  2. 2. Nanocomposites of Cellulose and Conducting Polymer for Electrical Energy Storage

    Author : Henrik Olsson; Leif Nyholm; Maria Strømme; Martin Sjödin; Johan Bobacka; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polypyrrole; Nanocomposites; Energy storage; Conducting polymers; Cellulose; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Abstract : The world’s increased energy storage demand, as well as the environmental concerns related to the combustion of fossil fuels, has triggered a transition to intermittent renewable energy sources as well as to electrical and hybrid vehicles. Current day rechargeable batteries are, due to the invention and development of lithium ion batteries, technologically well positioned to answer to some of these demands. READ MORE

  3. 3. On the electrochemical performance of energy storage devices composed of cellulose and conducting polymers

    Author : Petter Tammela; Leif Nyholm; Maria Strømme; Martin Sjödin; A Robert Hillman; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polypyrrole; supercapacitors; self-discharge; Teknisk fysik med inriktning mot nanoteknologi och funktionella material; Engineering Science with specialization in Nanotechnology and Functional Materials;

    Abstract : Applications that require electrical energy storage are becoming increasingly diverse. This development is caused by a number of factors, such as an increasing global energy demand, the advent of electric vehicles, the utilization of intermittent renewable energy sources, and advances in disposable and organic electronics.
