DFT study of thermoelectric performance of SrTiO3 doped by tantalum
Akeem Adekunle Adewale; Abdullah, Chik; Ruhiyuddin, Mohd Zaki; Faizul, Che Pa; Yeoh, Cheow Keat; Noorina Hidayu, Jamil (Universiti Malaysia Perlis (UniMAP), 2019-10)This paper deals with enhancement of thermoelectric performance of SrTiO3 - a perovskite-based material by doping Ti-site with Ta. The electronic and the thermoelectric transport properties of doped SrTiO3 were studied ... -
Effect of pyrolysis temperature on the synthesis of carbon fiber from natural organic waste
Shahrizam, Saad; Faizul, Che Pa; Mohd Mustafa Al-Bakri, Abdullah; Ruhiyuddin, Mohd Zaki; Murizam, Darus (Trans Tech Publications, 2014)Carbon fibers are produced from natural sources of water hyacinth plants that have been dried, ground and sieved to three different particle sizes of 600 μm, 300 μm and less than 300 μm. Through the analysis of data obtained ... -
Potential application of palm ash as a raw materials in production of green glass
Noorina Hidayu, Jamil; Mohd Mustafa Al Bakri, Abdullah; Faizul, Che Pa; Ruhiyuddin, Mohd Zaki; Murizam, Darus; Che Mohd Ruzaidi, Ghazali, Prof. Madya; Mohamed Faisol, Mohamed Nor (Scientific.Net/Trans Tech Publications, 2012-12)Oil Palm Ash is one of the abundance agricultural wastes found in Malaysia. This wastes need to be disposed properly. Oil palm ash contains compounds needed to produce glass. Most of raw materials (especially silica) used ... -

Noorina Hidayu, Jamil; Xian, W. Hui; Wan Mohd Arif, Wan Ibrahim; Faizul, Che Pa; Ruhiyuddin, Mohd Zaki (Trans Tech Publications, 2014)This study is to determine the properties and characterization of silicon carbide via grinding and heat treatment process. In this study, the raw materials used were waste glass and graphite powder. Silicon carbide was ... -
Study on milling periods on the iron mill scale particle size and properties
Ruhiyuddin, Mohd Zaki; Faizul, Che Pa; Murizam, Darus; A. R. M., Nazri (Trans Tech Publications, 2013)The relations between the milling periods with the iron mill scale particle size have been studied. Iron mill scale has been chosen for this research due to the nature of itself, as a by-product. From this research, the ... -
Synthesis and characterization of iron produced from iron mill scale
Ruhiyuddin, Mohd Zaki; Murizam, Darus; Khairel Rafezi, Ahmad, Dr. (Trans Tech Publications, 2014-01)In this project, iron mill scale has been used to produce iron powder that can be used within the Powder Metallurgy process. To achieve this objective, the iron mill scale needs to be refined. This involve the work of ...
