A study of ordered mesoporous carbon doped with Co and Ni as a catalyst of oxygen reduction reaction in both alkaline and acidic media
(Surface and Coatings Technology, 2018)
The incorporation of trace amounts (<0.2%) of Co and Ni noticeably enhanced the catalytic activity of nitrogen-free ordered mesoporous carbon (OMC) towards oxygen reduction reaction (ORR). (Co,Ni)-doped OMCs were characterized ...
Pt/C catalyst impregnated with tungsten-oxide – Hydrogen oxidation reaction vs. CO tolerance
(International Journal of Hydrogen Energy, 2019)
Hydrogen Oxidation Reaction (HOR) is anode reaction in Proton exchange membrane fuel cells (PEMFCs) and it has very fast kinetics. However, the purity of fuel (H 2 ) is very important and can slow down HOR kinetics, affecting ...
MicroRNA meta-signature of oral cancer: evidence from a meta-analysis
(Upsala Journal of Medical Sciences, 2018)
Aim: It was the aim of the study to identify commonly deregulated miRNAs in oral cancer patients by performing a meta-analysis of previously published miRNA expression profiles in cancer and matched normal non-cancerous ...
Hydrogen evolution reaction on bimetallic Ir/Pt(poly) electrodes in alkaline solution
(Electrochimica Acta, 2019)
Hydrogen evolution reaction (HER) was studied in alkaline solution on Pt(poly) electrode modified by spontaneously deposited Ir nanoislands. Comprehensive insight into the characteristics of the bimetallic Ir/Pt(poly) ...
Tailoring the structural and magnetic properties of Ni zigzag nanostructures using different deposition angles
(Materials Research Bulletin, 2019)
In this work we investigated the influence of different deposition angles on the structural and magnetic properties of nickel thin films obtained by Glancing Angle Deposition. The films were deposited onto glass substrates ...
Influence of laser-induced heating on MnO nanoparticles
(Journal of Raman Spectroscopy, 2018)
The phase changes of MnO nanoparticles under laser-induced heating have been studied. Previous confirmation of the existence of MnO phase was based on the X-ray diffraction measurements. Here, we report the experimental ...
Point-of-care amperometric determination of L-dopa using an inkjet-printed carbon nanotube electrode modified with dandelion-like MnO2 microspheres
(Microchimica Acta, 2019)
An electrochemical sensor is described for the determination of L-dopa (levodopa; 3,4-dihydroxyphenylalanine). An inkjet-printed carbon nanotube (IJPCNT) electrode was modified with manganese dioxide microspheres by ...
Differently shaped nanocrystalline (Fe, Y)3O4 and its adsorption efficiency toward inorganic arsenic species
(Nanotechnology, 2019)
Herein we report effects of partial substitution of Fe3+ by Y3+ in magnetite (Fe3O4) on morphology and inorganic arsenic species adsorption efficiency of the Fe3-xYxO4 nanoparticles formed. The series of Fe3-xYxO4 (x = ...
Formation of Ag nanoparticles in Si (100) wafers by single and multiple low energy Ag ions implantation
(Surface and Coatings Technology, 2019)
We investigated the structural and optical changes of Si (100) induced by single or multiple low energy silver ion irradiation with fluences up to 1016 ions/cm2. The irradiated samples were analyzed by the means of Rutherford ...
Anomalous magnetic properties of CaRuO3 probed by AC and DC magnetic measurements and by low Ti impurity doping
(Physical Review B, 2018)
Calcium ruthenate (CaRuO3) is widely believed to be located close to a quantum critical point due to the strong non-Fermi-liquid behavior expressed in the temperature dependence of electronic transport, specific heat, ...
