The effect of space holder content and decomposition methods in fabrication of aluminum foams by powder metallurgy method using carbamide space holder/A. H. Amirah, M. S. Nurulakmal, And A. S. Anasyida The effect of space holder amount and decomposition methods on the morphology, density and porosity and compressive properties of aluminum foams were investigated. Aluminum foam was fabricated by powder metallurgy method using spherical carbamide as space holder using three different decomposition method of carbamide includes; dissolution process, ... | 3/5/2020 | 1/1/2016 | Amirah A.

The effect of space holder content and sintering temperature of magnesium foam on microstructural and properties prepared by sintering dissolution process (sdp) using carbamide space holder/S.F. Aida , H. Zuhailawati , A.S. Anasyida Magnesium foam has gained a significant interest in structural application due to low density and greater strength than aluminium foam. In this study, magnesium foam was produced by sintering dissolution process (SDP) using spherical carbamide as the space holder. Magnesium foam was prepared using SDP at sintering temperatures (600 'C, 630 0 C, 650... | 3/5/2020 | 1/1/2017 | Aida S.F. - Author Zuhailawati H. - Author Anasyida A.S. - Author | |
The study of direct thermal-to-electricity conversion using thermionic heat cell device/ Assoc Prof. Dr. Khairudin Mohamed Thermionic energy conversion (TEC) is the direct conversion of heat into electricity by the mechanism of thermionic emission, the spontaneous ejection of hot electrons from a surface in vacuum environment. There are two major obstacles for achieving highly efficient TECs; the strict need for low emitter and collector work functions, and the mutual ... | 9/24/2020 | 11/1/2015 | Assoc Prof. Dr. Khairudin Mohamed - Author | |

The study of the catalytic activity for graphene formation under atmospheric pressure chemical vapor deposition/ Prof. Ir. Dr. Abdul Rahman Mohamed Large area graphene (LAG) were synthesized and grown on copper (Cu) foil and nickel (Ni) foil. The synthesis were carried out using atmospheric pressure chemical vapor deposition and methane
decomposition. The highly uniform and i-•' of high quality LAG was produced and was evaluated by Raman spectroscopy mapping, electron diffraction and. trans.m... | 6/18/2019 | 6/12/2019 | Prof. Ir. Dr. Abdul Rahman Mohamed - Author | |
Time-dependency behavior of steel fiber reinforced shotcrete lining under rock overstressing using shotcrete model / Heyam Shaalan A numerical analysis is implemented to estimate the time-dependent behavior of the steel fiber reinforced shotcrete lining (SFRS) using the constitutive model of shotcrete. Based on the concept of elasto—plastic strain hardening/softening plasticity, a new model of shotcrete is formulated, in which the time dependent strength, stiffness, creep and ... | 3/9/2020 | 1/1/2016 | Heyam Shaalan - Author |
