Study on physical and chemical properties of fly ash from different area in Malaysia
(Trans Tech Publications, 2013-12)
Fly ash is residue from the combustion of coal which widely available in worldwide and lead to waste management proposal. Moreover, the use of fly ash is more environmental friendly and save cost compared to OPC. Fly ash ...
Structural and optical studies of Eu³⁺ doped nanocrystalline tellurite glass
(Universiti Malaysia Perlis, 2014)
A series of transparent glasses with composition (80-x) TeO2 - 15 MgO - (x) Eu2O3, over the concentration region of 0 - 2.5 mol% were obtained using conventional melt-quenching technique. The nanocrystalline glass samples ...
The influence of aluminium doping and oxygenation on the porperties of YBa₂Cu₃-ₓAlₓO₆.₅+δ (0≤x≥0.045) HTSC
(Universiti Malaysia Perlis, 2013)
The effect of Al₂O₃ particle addition on the crystal structure and superconducting properties of YBa₂Cu₃O₆.₅+δ (YBCO) ceramics is systematically studies. Samples were synthesized using a solid reaction to prepare YBa₂Cu₃O7-δ ...
Synthesis, structural, surface morphology, optical and electrical properties of silver oxide nanoparticles
(Universiti Malaysia Perlis, 2016)
Silver oxide (Ag₂O) nanoparticles were synthesized using a wet chemical technique. The synthesized nanoparticles were investigated by X-ray diffraction analysis (XRD), scanning electron microscopy (SEM), transmission ...
Microstructure study on volcano ash geopolymer aggregate at different sintering temperature
(Trans Tech Publications, 2014)
Recent research shows that the by-product materials such as fly ash can be used as raw material in producing aggregates and lightweight aggregates. The usage of this material can improve the quality of the aggregates ...
Comparison of original and sintered LUSI mud from East Java, Indonesia as raw material for making a geopolymer
(American Scientific Publishers, 2013-01)
This paper presents the characterization of LUSI mud from East Java, Indonesia, as a potential raw material for making a geopolymer. Two types of LUSI mud were analyzed, i.e., original LUSI mud and LUSI mud that had been ...
Characterization of LUSI mud volcano as geopolymer raw material
(Trans Tech Publications, 2012)
The mud of mud volcano samples were collected from an eruption site named 'LUSI' (Lumpur "mud" -Sidoarjo), East Java, Indonesia for characterization. Analysis showed that, the major constituents of mud are SiO 2 and Al 2O ...
A preliminary study on structural and optical properties of heat treated NB2O5 nanostructure
(Universiti Malaysia Perlis (UniMAP), 2023-01)
Annealing is a heat treatment that alters the physical and sometimes chemical properties of
a material to improve their crystalline structure and other important properties. This work
presents the effect of post heat ...
