  2. 1. Sustainable porous organic materials : Synthesis, sorption properties and characterization

    Author : Fredrik Björnerbäck; Niklas Hedin; Knut Irgum; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; porous materials; sorbents; microporous; CO2 capture and separation; gas adsorption; activated carbon; humins; hypercrosslinked polymers; sustainable; Materials Chemistry; materialkemi;

    Abstract : The resources available to us humans, including metals, minerals, biomass, air, water, and anything else on the planet, are being used at an increasing rate. This anthropogenic use of resources both depletes the resources and has negative impacts on other resources, e.g. the biosphere. READ MORE

  4. 2. From hydrothermal carbonization to blue hydrochars and activated carbons : Adsorption of volatile organic compounds and heavy metals

    Author : Vahid Saadattalab; Niklas Hedin; Satu Ojala; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrothermal carbonization; hydrochars; activated carbon; volatile organic compounds; heavy metals; materialkemi; Materials Chemistry;

    Abstract : Hydrothermal carbonization of carbohydrate and biomass is a straightforward method for preparing hydrochars at low temperature. Hydrochars are more carbonized than their precursors. Hydrochars themselves are carbon precursors for preparing activated carbons. Activated carbons are porous materials that can be used for water and air purification. READ MORE

  5. 3. Investigation of corrosion properties of metals for degradable implant applications

    Author : Karin Beaussant Törne; Jonas Weissenrieder; Wolf-Dieter Mueller; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biodegradable; metal; zinc; magnesium; corrosion; electrochemistry; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : Nedbrytbara metaller utgör en ny klass av biomaterial med potential attersätta permanenta material i tillfälliga applikationer. Detta för att minskarisken för långvariga biverkningar. READ MORE

  6. 4. Transition metal ion-chelating ordered mesoporous carbons as noble metal-free fuel cell catalysts

    Author : Johanna Dombrovskis; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mesoporous materials; electrocatalysis; EXAFS spectroscopy; fuel cell; transition metals; carbon;

    Abstract : Polymer electrolyte membrane fuel cells offer promising possibilities for clean and efficient chemical to electrical energy conversion, though their high price makes them financially unappealing. This is to a large part due to the high cost of the noble metal catalyst used in fuel cells, which makes development of new, cheap and active catalyst materials necessary. READ MORE

  7. 5. Functionalized Porous Carbon Fiber Electrodes for Applications in Electrochemical Flow Cells

    Author : Arman Molaei; Xavier Crispin; Magda Titirici; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Carbon-based devices; Supercapacitor; Deoxygenation electrolyser; BBL polymer;

    Abstract : Corrosion of metals in close-loop cooling or heating systems originates from tiny leakages at joints releasing oxygen into the thermal fluids. The presence of dissolved oxygen (DO) in thermal fluids, such as water with various additives forms a rust coating and some rust particles are released in the fluids and accumulate in an undesired place.
