The density of fluids is easier to be measured compared to solids where the density measurement of solids was lagging behind because of their difficulties in measuring the volume especially in a porous and shapeless material. The density of a solid material can be ambiguous, depending on exactly how its volume is defined. The aim of this research is to develop a simple technique to measure the density of solid materials which consist of shapeless m aterial by using vacuum system. In this study, steel, rice and sweets (Clorets) were used as the shapeless materials. The density of steel is 7.61 g/mL, rice is 1.60 g/mL and for Clorets is 1.2 g/mL. The development of simple technique for measuring the density of solid materials has been succeeded by using vacuum system and the density of shapeless material can be measured. 160 3rd ICYC 2010 Universiti Sains Malaysia MAT-P14 23rd-25th June 2010 STUDY THE STRUCTURE OF MOLYBDENUM OXIDE-ZIRCONIA CATALYST BY FTIR SPECTROSCOPY 1* Sugeng Triwahyono, Aishah Abdul Jalil, Nurun Najwa Ruslan, Sharifah Najiha Timmiati, Ainul 1 Hakimah Karim and Nurrulhidayah Ahmad Fadzlillah 2 1 2 1 Ibnu Sina Institute for Fundamental Science Studies, Universiti Teknologi Malaysia, 81310 UTM Skudai, Johor, Malaysia 2 Faculty of Chemical & Natural Resources Engineering,Universiti Teknologi Malaysia, 81310 UTM Skudai, Johor, Malaysia E-mail: [email protected] The mechanism of the generation of protonic acid sites from molecular hydrogen on MoO 3-ZrO2 was studied by IR spectroscopy. The spectral changes in the Mo=O stretching and the OH stretching regions were observed in response to the exposure to hydrogen. By heating in the presence of hydrogen, the -1 -1 Mo=O stretching bands at 1000 cm eroded and a new peak around 990 cm was developed after -1 exposing to H2 for 2 hours. A broad OH stretc...
