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

   Författare :Mylene Trublet; Oleg Antzutkin; Anna-Carin Larsson; Marina Maslova; Nigel Clayden; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

   Sammanfattning : Treatment of industrial waters containing heavy metal ions is essential before being discharged into the environment. Consequently, European regulations have been established to control and limit the amount of heavy metals released. LÄS MER

3. 2. Complexation of Thorium with Phosphates and Silicates under Repository Conditions

   Författare :Andreas Knutsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; AKUFVE; Liquid-liquid extraction; Silicates; Complexation; Stability Constants; Thorium; Phosphates;

   Sammanfattning : In order to make reliable performance assessments of the safety for planed underground repositories for spent nuclear fuel large amounts of chemical thermodynamical data is needed. In some cases the databases used for modeling the migration behavior of radionuclides in groundwater is missing data. LÄS MER

4. 3. Narrow-pore zeolites and zeolite-like adsorbents for CO2 separation

   Författare :Ocean Cheung; Niklas Hedin; Paul A. Wright; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CO2 separation; zeolites; phosphates; titanium silicates; ion exchange; flue gas CO2 capture; biogas upgrading; Materials Chemistry; materialkemi;

   Sammanfattning : A range of porous solid adsorbents were synthesised and their ability to separate and capture carbon dioxide (CO2) from gas mixtures was examined. CO2 separation from flue gas – a type of exhaust gas from fossil fuel combustion that consists of CO2 mixed with mainly nitrogen and biogas (consists of CO2 mixed with mainly methane) were explicitly considered.

5. 4. Biomimetic surfaces : Preparation, characterization and application

   Författare :Annika Borgh; Bo Liedberg; Fredrik Höök; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Self-assembled monolayers; biomimetic surfaces; phosphates; antifreeze; surface spectroscopy; Molecular physics; Molekylfysik;

   Sammanfattning : I denna avhandling beskrivs tillverkning, karaktärisering och tillämpning av ett antal biomimetiska ytor. Biomimetik är att härma naturen och grundtanken är att titta på hur naturen löst liknande problemställningar. LÄS MER

7. 5. The evolution of lunar breccias : U-Pb geochronology of Ca-phosphates and zircon using Secondary Ion Mass Spectrometry

   Författare :Fiona Karen Thiessen; Martin Whitehouse; Alexander Nemchin; Victoria Pease; Barbara Cohen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Moon; impact breccias; Apollo missions; impact event; Late Heavy Bombardment; zircon; Ca-phosphates; U-Pb; SIMS; geochronology; Geology; geologi;

   Sammanfattning : Planetary bodies in our Solar System, including the Moon, were exposed to an intense asteroid bombardment between ~4.5-3.8 Ga, shaping their surfaces and leaving visible “footprints” in the form of large impact basins. The end of this period (~4. LÄS MER
