Characteristics of developed granules containing phototrophic aerobic bacteria for minimizing carbon dioxide emission
(Elsevier Limited, 2015-08-01)
Photosynthetic process compromises the most effective and natural way for carbon recycling, in which photosynthetic bacteria utilized carbon dioxide (CO2) during the wastewater treatment processes. The aim of this study ...
Variation of air pollutant (particulate matter - PM10) in peninsular Malaysia: study in the southwest coast of peninsular Malaysia
(SYSCOM 18 SRL, 2015-09)
Particulate matter (PM10) received great attention due to its potential to cause adverse health effects. In this study, the variation of tne long-term PM10 concentration from monitoring records in the southwest coast of ...
Optimization of silver-assisted nano-pillar etching process in silicon
(Elsevier, 2015-12-01)
In this study, a respond surface methodology (RSM) model is developed using three-level Box-Behnken experimental design (BBD) technique. This model is developed to investigate the influence of metal-assisted chemical etching ...
Simultaneous wastewater treatment and power generation with innovative design of an upflow membrane-less microbial fuel cell
(Springer International Publishing, 2015-05-01)
Abstract The objective of this study was to evaluate the performance of an upflow membrane-less microbial fuel cell (UFML MFC) with various types of carbon material as cathodes in power output and chemical oxygen demand ...
Effect of frying on the rheological and chemical properties of palm oil and its blends
(Springer India, 2015-03)
The aim of this research was to determine the changes in the physicochemical properties of palm oil and its blends by FTIR and rheological measurements. Application of heat produces some chemical compounds as impurities ...
Heteroepitaxial growth of vacuum-evaporated Si-Ge films on nanostructured silicon substrates
(Faculty of Science and Technology, Universiti Kebangsaan Malaysia, 2015)
In this study, a low-cost vacuum-evaporated technique is used in the heteroepitaxial growth of Si-Ge films. Three different surface variations are employed: i.e. polished Si, Si micropyramids and Si nanopillars profiles. ...
Evaluation on the molecular structure of azo dye in photocatalytic mineralization under solar light irradiation
(Taylor and Francis Ltd., 2015-08-21)
The aim of this study was to investigate the effects of number of sulphonic groups on solar photocatalytic degradation of Acid Orange 7 (AO7), Orange G (OG), New Coccine (NC), Reactive Black 5 (RB5) and Reactive Green 19 ...
Novel approach for assessing psychomotor domain in engineering technology courses
(Universiti Tun Hussein Onn (UTHM), 2015-10)
Evaluation of laboratory experiences of engineering technology students do not include the assessment of psychomotor domain due to lack of suitable measuring tool. This is despite the importance of this domain in engineering ...
Kinetic removal of Cr⁶⁺ in aqueous solution by carboxymethyl cellulose-stabilized nano zero-valent iron particles
(Society of Chemists and Technologists of Macedonia, 2015)
Carboxymethyl cellulose (CMC) was used in the chemical reduction method for producing dispersible nano zero-valent iron (nZVI) particles served as reactive, mobile and convenient adsorbent. CMC-stabilized nZVI particles ...
Effect of NaOH concentration on microstructure of boiler ash based geopolymer
(Trans Tech Publications Ltd., 2015)
Boiler ash is one of the waste material from palm oil processing industry and it was widely available. The role of alkaline activator in geopolymer is important for its mechanical properties. NaOH and sodium silicate ...
