    Abstract : Deep Learning models have seen great application in demanding tasks such as machine translation and autonomous driving. However, building such models has proved challenging, both from a computational perspective and due to the requirement of a plethora of annotated data. READ MORE

  3. 12. Analytical Methods for High Molecular Weight UV Stabilizers

    University essay from KTH/Kemi

    Author : Elin Ljungström; [2022]
    Keywords : hindered amine light stabilizers; light stabilizers; polyolefins; LC-MS; HPLC; hindrade aminljusstabilisatorer; ljusstabilisatorer; polyolefiner; LC-MS; HPLC;

    Abstract : Utomhusprodukter gjorda i plast är sårbara för nedbrytning på grund av UV-energi från solljus. För att stoppa denna fotonedbrytning används UV-stabilisatorer i plastmaterial; en av huvudkategorierna är hindrade aminljusstabilisatorer (HALS, hindered amine light stabilizers). READ MORE

  4. 13. A photodegradation study of conjugated polymers for organic solar cells by absorption spectroscopy and atomic force microscopy

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Johansson André; [2021]
    Keywords : OSC; solar cells; active layer; polymer; degradation;

    Abstract : The effect of light exposure in ambient air on thin films made from an electron acceptor polymer poly{[N,N'-bis(2-octyldodecyl)naphthalene-1,4,5,8-bis(dicarboximide)-2,6-diyl]-alt-5,5'-(2,2'-bithiophene)} (N2200), an electron donor polymer Poly[[2,3-bis(3-octyloxyphenyl)-5,8-quinoxalinediyl]-2,5-thiophenediyl] (TQ1) and their blends, has been studied using UV-vis spectroscopy and Atomic Force Microscopy (AFM). For solutions of TQ1, N2200 and blends, the linearity of the Beer-Lambert law for absorption spectroscopy has been verified. READ MORE
