132kV oil impregnated paper bushing transformer - design by CAD, analysed by FEM
(Horizon Research Publishing, 2019)
The Electric Field and Voltage Distribution (EFVD) are an important parameter for assessing high voltage bushing transformer performance. However, conducting laboratories experiment is dangerous, difficult and expensive ...
Microstructural studies of doped PEG Ag/TiO₂ thin film
(IOP Publishing Ltd, 2019-12)
Ag/TiO₂ thin film was prepared by the sol-gel method through the hydrolysis of titanium tetraisopropoxide and silver nitrate solution. Various amount of PEG was doped into the solution preparation to study the effect on ...
Seawater exposure effect on fly ash based geopolymer concrete with inclusion of steel fiber
(IOP Publishing Ltd, 2020-02)
Concrete is widely used in construction offshore such as concrete floating bridges and sea tank. This research is providing an alternative construction material to replace ordinary Portland cement (OPC) concrete known as ...
A review of geopolymer ceramic as a potential reinforcement material in solder alloys
(IOP Publishing Ltd, 2019-12)
Nowadays, lead-free solder has been currently used in electronic packaging technology as part of soldering material. Since SnPb was detected to produce toxicity and might harm the consumers, the usage of Pb solder has been ...
Effect of different ratio of geopolymer paste based fly ash-metakaolin on compressive strength and water absorption
(IOP Publishing Ltd, 2019-12)
This paper presents the effect of different solid to solid (S/S) ratio by mixing the fly ash and metakaolin as geopolymer paste on the compressive strength and water absorption. Fly ash is a waste materials produced by ...
Performance and characterization of geopolymer concrete reinforced with short steel fiber
(IOP Publishing Ltd, 2017-06)
In the recent years, geopolymer concrete are reporting as the greener construction technology compared to conventional concrete that made up of ordinary Portland cement. Geopolymer concrete is an innovative construction ...
Synthesis and characterization of TiO₂/SiO₂ thin film via SolGel method
(IOP Publishing Ltd, 2017-06)
TiO₂/SiO₂ thin films were prepared by sol-gel spin coating method. Structural, surface morphology and optical properties were investigated for different annealing temperatures at 300°C, 400°C and 500°C. X-ray diffraction ...
Study on fired clay bricks by replacing clay with palm oil waste: effects on physical and mechanical properties
(IOP Publishing Ltd, 2017-06)
Palm oil is one of the major agricultural industries in Malaysia. Due to the poor management system, the discarded palm oil waste has always been linked to the environment issues. During processing of palm oil, a considerable ...
Fabrication of porous ceramic-geopolymer based material to improve water absorption and retention in construction materials: a review
(IOP Publishing Ltd, 2017-06)
Porous ceramic nowadays has been investigated for a variety of its application such as filters, lightweight structural component and others due to their specific properties such as high surface area, stability and permeability. ...
Surface topographical modification of coronary stent: a review
(IOP Publishing Ltd, 2017-06)
Driven by the urge of mediating the inflammatory response from coronary stent implant to improve patency rates of the current coronary stent, concern has been focusing on reducing the risk of in-stent restenosis and ...
