    Nečas, David; Yacoot, Andrew; Valtr, Miroslav; Klapetek, Petr (IOP Publishing, 2023-05-01)
    Periodic structures are often found in various areas of nanoscience and nanotechnology with many of them being used for metrological purposes either to calibrate instruments, or forming the basis of measuring devices such ...

  • Enhanced Adhesion of Electrospun Polycaprolactone Nanofibers to Plasma-Modified Polypropylene Fabric 

    Janů, Lucie; Dvořáková, Eva; Polášková, Kateřina; Buchtelová, Martina; Ryšánek, Petr; Chlup, Zdeněk; Kruml, Tomáš; Galmiz, Oleksandr; Nečas, David; Zajíčková, Lenka (MDPI, 2023-03-28)
    Excellent adhesion of electrospun nanofiber (NF) to textile support is crucial for a broad range of their bioapplications, e.g., wound dressing development. We compared the effect of several low- and atmospheric pressure ...

  • Interplay between multipole expansion of exchange interaction and Coulomb correlation of exciton in colloidal II-VI quantum dots 

    Klenovský, Petr; Valdhans, Jakub; Krejčí, Lucie; Valtr, Miroslav; Klapetek, Petr; Fedotova, Olga (IOP Publishing Ltd, 2022-03-01)
    We study the effect of Coulomb correlation on the emission properties of the ground state exciton in zincblende CdSe/ZnS core-shell and in wurtzite ZnO quantum dots (QDs). We validate our theory model by comparing results ...

  • Optical characterization of inhomogeneous thin films with randomly rough boundaries 

    Vohánka, Jíří; Ohlídal, Ivan; Buršíková, Vilma; Klapetek, Petr; Kaur, Nupinder Jeet (Optica Publishing Group, 2022-01-17)
    An inhomogeneous polymer-like thin film was deposited by the plasma enhanced chemical vapor deposition onto silicon single-crystal substrate whose surface was roughened by anodic oxidation. The inhomogeneous thin film with ...

  • Amine modification of calcium phosphate by low-pressure plasma for bone regeneration 

    Kodama, Joe; Harumningtyas, Anjar Anggraini; Ito, Tomoko; Michlíček, Miroslav; Sugimoto, Satoshi; Kita, Hidekazu; Chijimatsu, Ryota; Ukon, Yuichiro; Kushioka, Junichi; Okada, Rintaro; Kamatani, Takashi; Hashimoto, Kunihiko; Tateiwa, Daisuke; Tsukazaki, Hiroyuki; Nakagawa, Shinichi; Takenaka, Shota; Makino, Takahiro; Sakai, Yusuke; Nečas, David; Zajíčková, Lenka; Hamaguchi, Satoshi; Kaito, Takashi (Nature Portfolio, 2021-09-01)
    Regeneration of large bone defects caused by trauma or tumor resection remains one of the biggest challenges in orthopedic surgery. Because of the limited availability of autograft material, the use of artificial bone is ...

  • Deposition penetration depth and sticking probability in plasma polymerization of cyclopropylamine 

    Michlíček, Miroslav; Blahová, Lucie; Dvořáková, Eva; Nečas, David; Zajíčková, Lenka (Elsevier, 2021-02-02)
    Understanding the role of substrate geometry is vital for a successful optimization of low-pressure plasma polymerization on non-planar substrates used in bioapplications, such as porous materials or well plates. We ...
