Various types of semiconductor photocatalysts modified by CdTe QDs and Pt NPs for toluene photooxidation in the gas phase under visible light
PublicationA novel synthesis process was used to prepare TiO2 microspheres, TiO2 P-25, SrTiO3 and KTaO3 decorated by CdTe QDs and/or Pt NPs. The effect of semiconductor matrix, presence of CdTe QDs and/or Pt NPs on the semiconductor surface as well as deposition technique of Pt NPs (photodeposition or radiolysis) on the photocatalytic activity were investigated. The as-prepared samples were characterized by X-ray powder diffractometry (XRD),...

Local structural and chemical ordering of nanosized Pt(3±δ)Co probed by multiple-scattering x-ray absorption spectroscopy
PublicationThis work reports a detailed investigation of the local structure and chemical disorder of a Pt(3±δ)Co thin film and Pt(3±δ)Co nanoparticles. We have used a combination of techniques including x-ray absorption spectroscopy (XAS), x-ray diffraction (XRD), and high-resolution transmission electron microscopy (TEM). The important effect of chemical ordering on pair and three-atom configurations has been studied using computer simulations...

Nanocrystalline Polymer Impregnated [Fe(pz)Pt(CN)4] Thin Films Prepared by Matrix-Assisted Pulsed Laser Evaporation
PublicationIn this work, the fabrication of [Fe(pz)Pt(CN)4] (pz = pyrazine) thin films by means of matrix-assisted pulsed laser evaporation (MAPLE) was investigated. As starting material, a cryogenically cooled suspension of anocrystalline [Fe(pz)Pt- (CN)4] (0.35wt.-%) in a mixture of 1,1-dichloroethane and polyethylene glycol (PEG) was used. Films of a thickness up to 150–200 nm were deposited on Si substrates by laser ablation at λ = 1064...

Mono- and bimetallic (Pt/Cu) titanium(IV) oxide core–shell photocatalysts with UV/Vis light activity and magnetic separability
PublicationTitanium(IV) oxide is one of the most widely investigated photocatalysts. However, separation of nano-sized particulate titania might result in profitless technologies for commercial applications. Additionally, bare titania is almost inactive under the Vis range of solar spectrum due to its wide bandgap. Therefore, the present study aims to prepare novel coreinterlayer- shell TiO2 magnetic photocatalysts modified with metal nanoparticles...

The phenomenon of increasing capacitance induced by 1T/2H-MoS2 surface modification with Pt particles – Influence on composition and energy storage mechanism
PublicationIn this paper, several approaches to the synthesis of molybdenum-based electrode materials for supercapacitors are presented, including anodization, hydrothermal process and annealing. For the material prepared via anodization of a molybdenum plate, followed by a hydrothermal process in thiourea aqueous solution, a thorough study of the Pt-surface modification through repetitive cycling in 1 M sulfuric acid with Pt acting as a...

Segmentacja obrazów medycznych przy ograniczonej liczbie adnotacji
PublicationW dziedzinie badań klinicznych i opieki zdrowotnej tradycyjne podejście w uczeniu głębokim polegające na wykorzystaniu dużych zbiorów danych jest trudne w realizacji. Przyczyną takiego stanu rzeczy są koszty znakowania obrazów medycznych, zwłaszcza w przypadku segmentacji obrazów medycznych. Jest to żmudna operacja, która zazwyczaj wymaga intensywnego znakowania pikseli wykonanego przez ekspertów – lekarzy. W tym rozdziale zaprezentowano...

Hearing aid operating in acoustical free field
PublicationAparatowanie bardzo małych dzieci (od 5 miesiąca życia) za pomocą standardowych protez słuchu natrafia na wiele trudności natury praktycznej. Dotyczy to procesu dopasowania aparatu słuchowego, czyli doboru jego ustawień stosownie do aktualnych charakterystyk ubytku słuchu dzieci. Tymczasem wczesne aparatowanie jest zagadnieniem o ogromnym zanczeniu dla rozwoju słuchu, mowy i ogólnej inteligencji dziecka. Referat prezentuje uzyskane...

Ocena zużycia energii i emisji szkodliwych związków chemicznych do środowiska w procesie wytwarzania pojemników przeznaczonych do przechowywania spożywczych napojów gazowanych i niegazowanych
PublicationW niniejszym artykule przedstawiono ocenę zużycia energii i emisji szkodliwych substancji związków chemicznych do środowiska w procesie wytwarzania pojemników przeznaczonych do przechowywania spożywczych napojów gazowanych i niegazowanych. W ocenie brano pod uwagę puszki aluminiowe, butelki szklane i butelki PET. Z przeprowadzonej analizy wynika, że najmniejszym zużyciem energii w procesie wytwarzania cechują się butelki PET, natomiast...
