• Selective recovery of phosphorus as AlPO4 from silicon-free CFB-derived fly ash leachate 

  Budhathoki, Roshan; Väisänen, Ari; Lahtinen, Manu (Elsevier BV, 2018)

  The prospect of phosphorus (P) recovery from siliceous fly ash was investigated. The phosphorus content in the pristine fly ash was 1.21%. Obtaining pure phosphorus products from fly ash is very challenging because of high ...

• Laser spectroscopy with an electrostatic ConeTrap 

  Kelly, S.; Campbell, P.; Cheal, B.; Eronen, Tommi; Geldhof, Sarina; Jokinen, Ari; Moore, Iain; Penttilä, Heikki; Pohjalainen, Ilkka; Rinta-Antila, Sami; Sonnenschein, Volker; Voss, Annika (Springer, 2017)

  A compact electrostatic trap has been designed and installed as part of the recent upgrades to the IGISOL IV facility. The ConeTrap provides an in vacuo optical pumping site for low energy (800 eV) ionic ensembles available ...

• Attributions and paradoxes of agency in socially sustainable development : perspectives from small-scale NGOs in Jinja, Uganda 

  Kärkkäinen, Anna (2014)

  During the past decades, sustainable development has become an important phenomenon in the global development discourse. The concept has been widely used by both large international bodies such as the United Nations as ...

• Experimental evidence on photo-assisted O− ion production from Al2O3 cathode in cesium sputter negative ion source 

  Tarvainen, O.; Kronholm, R.; Laitinen, M.; Reponen, M.; Julin, J.; Toivanen, V.; Napari, M.; Marttinen, M.; Faircloth, D.; Koivisto, H.; Sajavaara, T. (AIP Publishing, 2020)

  The production of negative ions in cesium sputter ion sources is generally considered to be a pure surface process. It has been recently proposed that ion pair production could explain the higher-than-expected beam currents ...

• Nanodevices by DNA based gold nanostructures 

  Tapio, Kosti (University of Jyväskylä, 2017)

  In this thesis DNA based structures were utilized to create gold nanostructures for nanosensing and nanoelectronic applications. In the past, both of these fields have been dominated by the conventional lithography methods, ...
