Nondestructive evaluation of the interface between ceramic coating and stainless steel by electromagnetic method
(IOP Conference Series, 2016-09-02)
Protecting coatings as thermal barrier coating (TBC) are used for yield improvement of equipment working at high temperature. Zirconia doped with yttria ceramics are considered a good TBC material due of its low thermal ...
Tobermorite synthesis under hydrothermal conditions
The influence of different hydrothermal conditions and starting materials on a preparation of tobermorite was examined. Tobermorite is a mineral, which, thanks to its composition and properties, is an important phase in ...
Inhibition of Hydrogen Evolution in Aluminium-phosphate Refractory Binders
The study deals with the possibilities of inhibition of the reaction of aluminium-phosphate binders with iron scale, which is contained in bauxite. This material is mixed with phosphate binders to form refractories. The ...
Effect of the Side Chains and Anode Material on Thermal Stability and Performance of Bulk-Heterojunction Solar Cells Using DPP(TBFu) 2 Derivatives as Donor Materials
An optimized fabrication of bulk-heterojunction solar cells (BHJ SCs) based on previously reported diketopyrrolopyrrole donor,ethyl-hexylated DPP(TBFu)2,aswellastwonewDPP(TBFu)2derivatives with ethyl-hexyl acetate and ...
Morphology versus Vertical Phase Segregation in Solvent Annealed Small Molecule Bulk Heterojunction Organic Solar Cells
The deep study of solvent annealed small molecules bulk heterojunction organic solar cells based on DPP(TBFu)2 : PC60BM blend is carried out. To reveal the reason of the solvent annealing advantage over the thermal one, ...
