Improving the optical properties of porphyrin ring with different substitutions: As candidate using in photosensitizer
(Universiti Malaysia Perlis (UniMAP), 2020-07)
In this research, different donor and acceptor substitutions were employed in attachment with porphyrin molecule and the optical properties improvement of it was studied. It was shown that the substituted porphyrin formation ...
Microstructure studies on the effect of the alkaline activators of fly ash-based geopolymer at elevated heat treatment temperature
(Trans Tech Publications, 2013)
Fly ash-based geopolymers are new binding materials produced to replace the ordinary Portland cement (OPC) used in concrete. In this research, the effect of alkaline activators on the compressive strength and the microstructure ...
Study on radioactivity components, water quality and microstructure characteristic of volcano ash as geopolymer artificial aggregate
(SYSCOM 18, 2013-06)
The assessments of radioactivity, water qualitytesting and microstructure characteristic of volcano ash have been examined. The measurement of the 226Ra, 232Th, 40K, and 238U were carried out using radioactive concentration ...
Feasibility of producing wood fibre-reinforced geopolymer composites (WFRGC)
(Trans Tech Publications, 2013)
Wood fibres have long been known as a fibre reinforcement for concrete. Due to its availability and low production cost, this natural fibre has been used in less developed country where conventional construction materials ...
Strength, density and water absoprtion of Palm oil boiler ash (POBA) geopolymer brick/IBS brick
(Trans Tech Publications Ltd., 2016-01)
Geopolymer or alkali-activated binder is produced by synthesizing aluminosilicate source materials with an alkaline activator solution. This study has been conducted to produce palm oil boiler ash (POBA) geopolymer brick/IBS ...
Correlation between Na 2SiO 3/NaOH ratio and fly ash/alkaline activator ratio to the strength of geopolymer
(Trans Tech Publications, 2012)
Geopolymer requires an alkaline activator to induce it pozzolanic property and to accelerate the geopolymerisation process. The geopolymerisation process occurs due to the mixing of fly ash, sodium silicate and sodium ...
Malaysian Foxtail grass - A potential source of natural/agro fibre for polymer composite panel
(Trans Tech Publications, 2013)
Foxtail grass, also known as 'rumput bulu' by the local people, is one of the fast growing grasses abundantly available all over Malaysia. A full grown Foxtail grass attains a height of about 0.5 - 1.5 meters. The fibres ...
Review on the various ash from palm oil waste as geopolymer material
(Advanced Study Center Co. Ltd., 2013)
The solid waste from palm oil mill industry has been increasing annually where it has been reported that the palm oil waste was produced 4 million tons/years in Malaysia only. Hence, the solution to overcome the problems ...
Orientation-based pairwise coarse registration with markerless terrestrial laser scans
(Copernicus Publications, 2019)
In this paper, pairwise coarse registration is presented using real world point cloud data obtained by terrestrial laser scanner and without information on reference marker on the scene. The challenge in the data is because ...
