  • The importance of observation of structural changes of lead acid battery active mass in special applications in the mining industry 

    Zimáková, Jana; Vaculík, Sebastian; Fryda, Daniel; Bača, Petr (Faculty of Mining, Ecology, Process Control and Geotechnologies (FBERG), Technical University of Kosice, 2015-10-26)
    Aby bylo možné používat olověných akumulátorů v mimořádně obtížných podmínkách v těžebním průmyslu, je velmi důležité pochopit děje, ke kterým dochází při trakčním provozu těžebních vozíků nebo při používání pomocného ...
  • A New Method for 2D Materials Properties Modulation by Controlled Induced Mechanical Strain 

    Gablech, Imrich; Pekárek, Jan; Klempa, Jaroslav; Vyroubal, Petr; Svatoš, Vojtěch; Neužil, Pavel (MDPI, 2018-12-07)
    This paper proposes a new method for characterization of 2D materials under the precisely specified conditions. It is achieved by integration of a 2D material as a field effect transistors structures with a piezoelectric ...
  • Simple and efficient AlN-based piezoelectric energy harvesters 

    Gablech, Imrich; Klempa, Jaroslav; Pekárek, Jan; Vyroubal, Petr; Hrabina, Jan; Holá, Miroslava; Kunz, Jan; Brodský, Jan; Neužil, Pavel (MDPI, 2020-01-28)
    In this work, we demonstrate the simple fabrication process of AlN-based piezoelectric energy harvesters (PEH), which are made of cantilevers consisting of a multilayer ion beam-assisted deposition. The preferentially (001) ...
  • Sodno-iontové akumulátory - budoucnost a aktuální vývoj 

    Libich, Jiří; Sedlaříková, Marie; Vondrák, Jiří; Máca, Josef; Čech, Ondřej; Fíbek, Michal; Čudek, Pavel; Chekannikov, Andrey; Fafilek, Günter (NZEE, 2019-05-15)
    The lithium-ion technology is widely known and spread technology. The based of this technology lies on transport of lithium ions during charging or discharging from one electrode to the other, this principle is call “rocking ...
  • Synthesis and Characterization of Porous Sulfur/MWCNTs Composites with Improved Performance and Safety as Cathodes for Li-S Batterie 

    Straková Fedorková, Andrea; Kazda, Tomáš; Gavalierova, Katarina; Gómez-Romero, Pedro; Shambel, Elena (ESG, 2018-01-01)
    Sulfur-carbon (S-C-MWCNTs) composites and sulfur-LiFePO4 (S-LFP-MWCNTs) composites were synthesised with MWCNTs additive by sulfur sublimation and solid state reaction. As prepared materials are characterized with scanning ...
  • The use of numerical simulation for the evaluation of special transparent glass resistance 

    Binar, Tomáš; Švarc, Jiří; Vyroubal, Petr; Kazda, Tomáš; Rolc, Stanislav; Dvořák, Aleš; Dostál, Petr (Elsevier, 2018-04-14)
    The paper is concerned with the use of numerical simulation for the evaluation of projectile interaction with an assembly composed of multiple materials (transparent armour). For the purpose of assessing the reliability ...
