Geopolymers are known for its high compressive but low tensile strength due to its brittle nature, which restricts the use of geopolymers as structural material. It is important to enhance their mechanical performance by...

The morphology of titanium, zirconium, and hafnium nanofilms deposited onto zirconia after annealing in vacuum at 1400, 1500, and 1600°C was studied. Nanofilms show a tendency to fragmentation; for titanium it begins at...

The kinetics of dispersion of thin niobium-copper films deposited onto leucosapphire, alumina and zirconia ceramics and annealed in vacuum at temperatures up to 1100 °C with different exposition times at each temperatur...
