    • Electro-catalytic and photo-catalytic reformation of CO2–reactions and efficiencies processes (Review) 

      Knoks, Ainars; Lesnicenoks, Peteris; Kleperis, Janis; Grinberga, Liga; Hodakovska, Julia; Klavins, Janis; Cikvaidze, Georgijs; Lukosevics, Ingars (Institute of Physics Publishing, 2019)
      Energy harvesting with lowest environmental impact is one of key elements for cleaner future. Photocatalytic as well as electrocatalytic CO2 reformation processes are considered as prominent methods. Thus, extensive research ...

    • Mass recovery of carbonated fabrics of glass fibres after isothermal heating 

      Pentjuss, E.; Balodis, J.; Vdovicenko, M.; Gabrusenoks, Jevgenijs; Bajars, Gunars; Petersone, L.; Kleperis, Janis (Institute of Physics Publishing, 2019)
      Leaching of Na+ ions in sodium oxide (Na2O) and silica (SiO2) containing glass is well investigated mainly due to its weak weathering. The object of this study was naturally (at room conditions) leached, steady state product ...

    • Nafion® and polyaniline composite modification with Li and Mg ions 

      Lozkins, Stanislavs; Hodakovska, Julija; Kleperis, Janis; Merijs - Meri, Remo (Institute of Physics Publishing, 2019)
      Modification of Nafion®-based samples with polyaniline (PANI) and positive charged ions could potentially allow achieving good proton conductivity at higher working temperatures what is observed in typical polymer electrolyte ...

    • Synthesis and studying of reduced few-layered graphene coatings in gas sensor applications 

      Lukosevics, Ingars; Lesnicenoks, Peteris; Kleperis, Janis (Institute of Physics Publishing, 2019)
      In this work reduced few-layered graphene (rFLG) nanoparticles were synthesized using electrochemical pulse exfoliation method from waste graphite crucibles. The regular change in voltage polarity in the synthesis process ...
