## Abstract Nickel catalysts supported on rice husk ashβalumina (Ni/RHAβAl~2~O~3~) were prepared by an incipient wetness impregnation method. Characterization included TGA, DSC, TPR, XRD, and BET. Results show that the decomposition of the nickel compound to nickel oxide was complete above 500 Β°C.
Nanocrystalline silicon carbide (nc-SiC) thin films have been grown on silicon (1 0 0) substrates by helicon wave plasma enhanced chemical vapor deposition technique and the photoluminescence of the films has been tuned from yellow to blue by changing the substrate temperatures (T s ). The resulting
