Ventilated brake discs are used in high speed automobiles. The brake disc is an important component in the braking system which is expected to withstand and dissipate the heat generated during the braking event. In the present work, an attempt is made to study the effect of vane-shape rotor on the flow-field and heat transfer characteristics for different configurations of vanes for different r...

Pillared carbon thin films were prepared from the thermal reduction of graphite oxide silylated with octyltrichlorosilane and then dimethyldichlorosilane. The interlayer spacing of the resulting pillared carbon thin film was 1.29 nm, and it contained hydrophobic Si–CH3 groups, excluding Si–OH ones. The resistance of it increased during the exposure to acetone vapor, while it was unchanged when ...

Kelantan and Terengganu are rich with beautiful carvings and distinctive motifs. Typically, they use motifs of flora, geometry and calligraphy rather than other motifs and also use as a benchmark of local architecture identity in Peninsular Malaysia. This study will present design analysis of carvings and motifs used on twelve pillared house in Kelantan and Terengganu. Carving in twelve pillare...

The layered structure of two smectites (montmorillonite and saponite) are modified by the insertion SiO2–ZrO2 nanoparticles, with a Si/Zr molar ratio 5, to form porous clay heterostructures (PCHs). These PCHs exhibit clear improvement textural acid properties in comparison starting clays, due formation pillared presence Zr species, which provide an increase amount Lewis sites. materials studied...

In this work, pillared bentonite with Al−Fe (Al−Fe−PILC) was synthesized and used as a heterogeneous Fenton-like catalyst in the oxidation of tartrazine azo-dye an aqueous solution. The modification Al-Fe mixed system concentrated medium, ultrasound assisted intercalation carried out, obtained characterized by XRF, XRD, N2 adsorption at 77 K. Al−Fe−PILC, using different amounts H2O2, expressed ...
