2. 1. Toward Safer Energy Storage Solution by Development of Fluorine-Free Battery Electrolyte

   Author : Elham Hosseini Bab Anari; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; sodium-ion batteries SIBs ; aqueous electrolyte; lithium-ion batteries LIBs ; safer electrolyte; fluorine-free salt;

   Abstract : Portable electronic devices such as mobile phones, laptops, cameras and electronic vehicles (EVs) which contain lithium-ion batteries (LIBs), are indispensable part of our modern society. The safety of conventional electrolytes of LIBs, composed of fluorinated lithium salts and organic solvents is the source of some concerns. READ MORE

4. 2. Synthesis of Novel Fluorine-Free Salts for Battery Electrolytes

   Author : Elham Hosseini Bab Anari; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; solid state electrolyte; aqueous electrolyte; lithium-ion batteries LIBs ; safer electrolyte; ionic liquid based electrolyte; water-in-bisalt WiBS electrolyte.; sodium-ion batteries SIBs ; fluorine-free salt;

   Abstract : Nowadays lithium-ion batteries (LIBs) are the dominant power sources of portable electronic devices such as mobile phones, laptops and cameras. Although recently their applications have extended to areas of electromobility and hybridization of vehicle, cost and safety issues remain as big obstacles for a smoother implementation. READ MORE

5. 3. Synthesis and applications of low silica zeolites from Bolivian clay and diatomaceous earth

   Author : Javier Gustavo Garcia Mendoza; Johanne Mouzon; Niklas Hedin; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Zeolites; Synthesis; clay; diatomite; adsorption; ion exchange; Chemical Technology; Kemisk teknologi;

   Abstract : The aim of the present work was to develop synthesis routes to produce synthetic zeolites with industrial attractiveness from non-expensive Bolivian raw materials, such as clays and diatomite. In particular, the work was focused on the synthesis of low-silica zeolites with the LTA and FAU structures. READ MORE

6. 4. Synthesis and functionalization of zeolites for NH3-SCR applications

   Author : Alexander Shishkin; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NH3-SCR; NOx reduction; Environmental catalysis; hydrothermal synthesis.; exhaust aftertreatment; zeolite functionalization;

   Abstract : In the strive towards decreasing carbon dioxide emissions from the growing transport sector, the interest for more fuel-efficient combustion engines operating under lean (oxygen excess) conditions has increased. The combustion products, however, formed in such engines contribute considerably to air pollution. READ MORE

7. 5. Titanium(IV) Phosphates : The Next Generation of Wastewater Sorbents
