Biohydrogen production in a continuous stirred tank bioreactor from synthesis gas by anaerobic photosynthetic bacterium: Rhodopirillum rubrum
(Elsevier Ltd., 2007-05)Hydrogen may be considered a potential fuel for the future since it is carbon-free and oxidized to water as a combustion product. Bioconversion of synthesis gas (syngas) to hydrogen was demonstrated in continuous stirred ... -
Bioinformatics: prospect, application and the way forward
(Universiti Malaysia Perlis, 2008)The world of bioinformatics is fast expanding into the mainstream of both molecular and computational biology. Bioinformatics is a new discipline that can be described as the science of collecting, modelling, storing, ... -
Biological hydrogen production from CO: Bioreactor performance
(Elsevier B.V., 2008-05-01)This paper presents an alternative solution to the current problem faced by the world; diminishing of fossil fuel. Bioconversion of synthesis gas to hydrogen as clean fuel was catalyzed by a photosynthetic bacterium, ... -
A biologically inspired hydrophobic membrane for application in pervaporation
(American Chemical Society, 2013-02)An artificial polydimethylsiloxane/polyphenylsulfone (PDMS/PPSU) membrane, which emulates the hydrophobic behavior of natural membranes, was synthesized. Hydrophobicity was achieved by coating the membrane surface sublayer ... -
A cascaded pervaporation process for dehydration of acetic acid
(Elsevier, 2014-02)Pervaporation is advantageous in separating close-boiling point mixtures, azeotropes, thermally sensitive compounds and purification of chemicals. However, one pervaporation unit may not be economically feasible to ... -
Catalytic dehydrogenation of methylcyclohexane (MCH) to toluene in a palladium/alumina hollow fibre membrane reactor
(Elsevier Ltd., 2013)A compact multifunctional Pd/alumina hollow fibre membrane reactor (HFMR) has been developed and used for the catalytic dehydrogenation of methylcyclohexane to toluene. The developed HFMR consists of a thin and defect-free ... -
Catalytic hydrogenation of carbon dioxide by platinum doped nickel oxide catalyst
(IDOSI Publications, 2010)The abundant amount of carbon dioxide gas from unwarranted activities into the atmosphere creating environmental pollution which leads to green house gas effect as well as global warming. However, carbon dioxide can utilized ... -
Characterizations of biocompatible and bioactive hydroxyapatite particles
(Elsevier B.V., 2013)The most common gene vectors used are virus based (viral gene vectors). These possess high immunological risk, so a non-viral gene vector maybe preferable. Nanocrystalline hydroxyapatite, HAp [Ca10(PO 4)6(OH)2] is an example ... -
Characterizations of hydroxyapatite (HAp) nanoparticles produced by sol-gel method
(AENSI Publisher All rights reserved, 2013-10)A pure ceramic powder of hydroxyapatite, Hap [Ca10(PO4)6(OH)2] can be produced by low temperature method namely sol-gel route. The sol-gel route is one of wet chemical synthesis techniques which produce the useful biomaterial ... -
Characterizations on the effect of processing of polymers blend with petroleum coke (part I)
(Trans Tech Publications, 2013)Global demand for plastics has grown significantly over the past decades, and will continue to expand with rising income levels in emerging economies; a number of approaches have been used to recycle polymer waste. While ... -
Chemically modified sugarcane bagasse as a potentially low-cost biosorbent for dye removal
(Elsevier B. V., 2010-12-15)The use of adsorbent prepared from sugarcane bagasse, an agro waste from sugar industries has been studied as an alternative substitute for activated carbon for the removal of dyes from wastewater. Adsorbents prepared from ... -
