Low-temperature processing of thin-film electrolyte for electrochemical devices.
PublicationPrzygowanie filmów elektrolitu jest jednym z najbardziej istotnych procesów technologicznych wytworzenia urządzeń elektrochemicznych takich jak ogniwa paliwowe. Zmniejszenie grubości filmu jest powiązane ze zmniejszeniem rezystancji elektrolitu, co bardzo korzystnie wpływa na wydajność ogniw paliwowych. W pracy tej przedstawiono niskotemperaturową (<1000C) metodę wytwarzenia filmów elektrolitu z tlenku cyrkonu stabilizowanego itrem...

Electrical conductivity of nanocrystalline Sm-doped CeO2 thin film.
PublicationGęste i nanokrystaliczne filmy tlenku ceru domieszkowane 20% samarem przygotowane na szafirze oraz próbki ceramiczne zostały przygotowane z prekursorów polimerowych. Ich konduktacja elektryczna była badana w funkcji temperatury i skorelowana z wielkością krystalitów. Model blokowo-warstwowy przewiduje mniejszą konduktacje próbki gdy wielkości krystalitów są mniejsze, w przypadku gdy rezystancja obszarów międzyziarnowych jest większa...

Synthesis of eosin modified TiO2 film with co-exposed {001} and {101} facets for photocatalytic degradation of para-aminobenzoic acid and solar H2 production
PublicationOwing to the increasing photosensitivity and DNA damage properties of para-aminobenzoic acid (PABA), concerns have been raised over the exposure of humans to PABA. Solar light-driven photocatalysis (SPC) provides a promising solution for the effective removal of organic pollutants especially when directed towards sulfate radical (SO4−) production. Herein, we have developed a sulfite-enhanced SPC using Eosin-Y sensitized TiO2/Ti...

EFFECT OF ANTIOXIDANTS ON THE STABILITY OF PITCH- BASED POLYMER TO THERMO-OXIDATIVE ACTION
PublicationThe influence of stabilizers – hydrogen donors – on the processes of thermooxidative destruction of pitch-based polymer has been investigated. It is shown that Irganox has not stabilizing effect on pitch-based polymer and melamine slightly retards the destructive process. A mixture of melamine and Irganox exhibits synergetic stabilizing effect and at the optimum ratio it can be used to prevent unwanted thermooxidative processes...

In situ spectroelectrochemical and theoretical study on the oxidation of a 4H-imidazole-ruthenium dye adsorbed on nanocrystalline TiO2thin film electrodes
PublicationTerpyridine 4H-imidazole-ruthenium(ii) complexes are considered promising candidates for use as sensitizers in dye sensitized solar cells (DSSCs) by displaying broad absorption in the visible range, where the dominant absorption features are due to metal-to-ligand charge transfer (MLCT) transitions. The ruthenium(iii) intermediates resulting from photoinduced MLCT transitions are essential intermediates in the photoredox-cycle...

Turbulent flow and heat transfer of a liquid film formed by impinging jet.
PublicationZaproponowano prosty model wymiany ciepła w turbulentnym filmie cieczowym utworzonym przez uderzająca strugę. Rozpatrzono dwa przypadki: przepływ rozwijający się i w pełni rozwinięty filmu cieczowego. W obu przypadkach model wyprowadzono na podstawie zmiany grubości filmu w wyniku działania sił bezwładności i sił tarcia. Wyznaczono profile prędkości w obu zakresach co umożliwia wyznaczenie współczynników wymiany ciepła.

Resistance noise in tio2-based thin film gas sensors underultraviolet irradiation
PublicationBadano możliwości wykorzystania fluktuacji rezystancji w cienkich warstwach TiO2 do wykrywania gazów. Pomiary przeprowadzono, gdy próbka była oświetlona promieniowaniem ultrafioletowym o długości 370nm, w obecności gazu H2S. Stwierdzono, że fluktuacje rezystancji są indukowane promieniowaniem ultrafioletowym i pozwalają na wykrycie obecności H2S w stężeniu do 1.5 ppm.
