    Electrochemically deposited nanocrystalline InSb thin films and their electrical properties
    (Cambridge : Royal Society of Chemistry, 2016) Hnida, K.E.; Bäßler, S.; Mech, J.; Szaciłowski, K.; Socha, R.P.; Gajewska, M.; Nielsch, K.; Przybylski, M.; Sulka, G.D.
    We present an electrochemical route to prepare nanocrystalline InSb thin films that can be transferred to an industrial scale. The morphology, composition, and crystallinity of the prepared uniform and compact thin films with a surface area of around 1 cm2 were investigated. The essential electrical characteristics such as conductivity, Seebeck coefficient, the type, concentration and mobility of charge carriers have been examined and compared with InSb nanowires obtained in the same system for electrochemical deposition (fixed pulse sequence, temperature, electrolyte composition, and system geometry). Moreover, obtained thin films show much higher band gap energy (0.53 eV) compared to the bulk material (0.17 eV) and InSb nanowires (0.195 eV).

    PTFEP-Al2O3 hybrid nanowires reducing thrombosis and biofouling
    (Cambridge : Royal Society of Chemistry, 2019) Haidar, Ayman; Ali, Awadelkareem A.; Veziroglu, Salih; Fiutowski, Jacek; Eichler, Hermann; Müller, Isabelle; Kiefer, Karin; Faupel, Franz; Bischoff, Markus; Veith, Michael; Aktas, Oral Cenk; Abdul-Khaliq, Hashim
    Thrombosis and bacterial infection are major problems in cardiovascular implants. Here we demonstrated that a superhydrophobic surface composed of poly(bis(2,2,2-trifluoroethoxy)phosphazene) (PTFEP)-Al2O3 hybrid nanowires (NWs) is effective to reduce both platelet adhesion/activation and bacterial adherence/colonization. The proposed approach allows surface modification of cardiovascular implants which have 3D complex geometries. © 2019 The Royal Society of Chemistry.
