Vasylyev OD1*, Brodnikovskyi YM1, Brychevskyi MM1, Polishko IO1, Ivanchenko SE2 and Vereshchak VG3
The paper is a short surwey of the R&D activity of Laboratory for Ceramic Fuel Cells at Frantcevych Institute for Problems of Materials Science, Ukraine, on their way from cubic zirconia powder development to creation and elaboration of Ceramic (Solid Oxide) Fuel Cells. Such the research topics, which are important for the further development of Ceramic Fuel Cells, like 1Ce10ScSZ zirconia powders, formation...
Development of Robust Tri-Bore Hollow Fiber Membranes for the Control of Dissolved Oxygen in Water
Tri-bore hollow fiber (HF) membranes with a triangular outer geometry were fabricated from polyvinylidene fluoride (PVDF) and explored for water deoxygenation. The representative membranes were hydrophobic and porous as seen from the contact angle of 94o and the porosity of 75%. The maximum load, elongation at break and the tensile stress of the tri-bore HF membranes were 3.90 N, 37.81% and 1.27 MPa...

Xia Y*, Sun S*, Meng L, Zhao Z, Zhu X, Xiao Z and Tu Y
Ag-C nanofibers membranes were fabricated using electrospinning method by combing with preoxidation and carbonization processes, the structures, morphologies and electrical performances,were characterized by X-ray diffraction, scanning electron microscopy and four probe instrument. And the influence of carbonization process with different carbonized temperatures on the structures, morphologies and...
Overview on Transparent Conducting Oxides and State of the Art of Low-cost Doped ZnO Systems
Jayathilake DSY* and Nirmal Peiris TA
Transparent conducting oxides (TCOs) have become an integral part of modern life through their essential role in touch screen technology. The growing demand for cheap and superior transparent conducting layers, primarily driven by the smart phone market, has led to renewed efforts to develop novel TCOs. Currently, the most widely used material for transparent conducting applications is Sn-doped indium oxide(ITO)...
New Strategies and Attempts to Improve Glass Ionomer Dental Cements
Glass ionomer dental cements are widely used in dentistry due to the high adhesion to the teeth, low contraction during the setting reaction, continuous release of fluoride ions and biocompatibility. The cements are made of an inorganic polymeric oxide mixed with a mixture of organic acids, i.e.,...
