  2. 1. Cellulose solutions in aqueous hydroxide bases

    Author : Beatrice Swensson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose; dissolution; NaOH; aqueous; solvent; quaternary ammonium hydroxide;

    Abstract : Cellulose is a renewable and widely available carbohydrate polymer whose utility for mankind only increases as we move towards a circular bioeconomy. Unlike most plastics or metals, it cannot be melted, and therefore, solution processing is important. READ MORE

  4. 2. Dissolution of cellulose in aqueous hydroxide base solvents

    Author : Beatrice Swensson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; aqueous; NaOH; quaternary ammonium hydroxide; solvent; cellulose; dissolution;

    Abstract : As we move towards a circular bioeconomy, new and advanced materials based on cellulose are constantly developed. Unlike most plastics or metals, cellulose cannot be melted, and therefore dissolution is an important tool for processing of cellulose but also for analytical purposes. READ MORE

  5. 3. Surface Modifications and Applications of Aqueous Silica Sols

    Author : Peter Greenwood; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; applications; Surface modification; aqueous; silica sol; silane; colloidal silica; titania;

    Abstract : Methods of modifying the surface of the particles of colloidal silica were developed and the effects of surface modification on the properties of colloidal silica were studied.Gamma-glycidoxypropyltrimethoxysilane (GPTMS) readily reacts with water to yield a hydrolysed silane that reacts readily with the silica surface.

  7. 5. Rechargeable Aqueous Batteries Based on Available Resources : Investigation and Development towards Efficient Battery Performance

    Author : Mylad Chamoun; Dag Noréus; Gunnar Svensson; Jekabs Grins; Ann Mari Svensson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; rechargeable aqueous batteries; alkaline electrolytes; aqueous sulfate electrolytes; zinc electrodes; manganese dioxide electrodes; iron electrodes; air electrodes; oxygen electrocatalysts; Inorganic Chemistry; oorganisk kemi;

    Abstract : Batteries employing water based electrolytes enable extremely low manufacturing costs and are inherently safer than Li-ion batteries. Batteries based on zinc, manganese dioxide, iron, and air have high energy relevancy, are not resource restricted, and can contribute to large scale energy storage solutions. READ MORE
