Fabrication of Amorphous silicon Microgap Structure for Energy Saving Devices
(Universiti Kebangsaan Malaysia, 2011-11-18)
We report here the fabrication of microgaps electrodes on amorphous silicon using low cost techniques such as vacuum deposition and conventional lithography. Amorphous silicon is a low cost material and has desirable ...
Preliminary Studies on Antimicrobial Activity of Extracts from Aloe Vera Leaf, Citrus Hystrix Leaf, Zingiber Officinale and Sabah Snake Grass Against Bacillus Subtilis
(EDP Sciences, 2018)
Herbal plants have several potential antimicrobial activities either as antifungal or antibacterial to fight against the disease and pathogen that attack the plants. The extractions of the Aloe vera leaf, Citrus hystrix ...
Effect of kenaf fibre Mat layers and Zinc Oxide Nanoparticle Concentration on the Mechanical and Thermal Properties of ZnONPs/kenaf/polyester Composites
(IOP Publishing, 2018)
Zinc oxide nanoparticle kenaf polyester composite (ZnONPs/kenaf/polyester)
containing 1, 2, 3 and 4 layers of kenaf fibre treated with 40nm 2% (w/w) and 5 % (w/w ) of
ZnONPs were prepared and characterised to evaluate ...
Amino-propyltriethoxysilane Modified Heavy Metal Sensor Based on Silicon Nanowire Arrays
(IOP Publishing, 2018)
Safety of consuming water from various resources can be questioned nowadays due to high content of material that is highly possible to have toxic content and cause permanent damage to human itself. Possible toxic content ...
Effect of Kenaf Fibre Layers on Mechanical and Thermal Properties of Kenaf/Unsaturated Polyester Composites
(IOP Publishing, 2018)
Composites of kenaf/unsaturated polyester containing 1layer up to 4 layers of kenaf fibre were studied to evaluate the mechanical and thermal properties. These composites were compared with a control system containing ...
Modelling Simulation of Organic and Inorganic Interaction Based on First Principle Calculation
(IOP Publishing, 2018)
The student presented theoretically interaction of organic and inorganic based on the electrostatic interaction created by the ssDNA interaction with sensor active surface, the ssDNA strand was immobilised on silicon-based ...
Structural, Optical, Electrical, and Photoresponse Properties of Postannealed Sn-Doped ZnO Nanorods
(Hindawi Limited, 2013)
Tin (Sn) doped ZnO nanorods were synthesized on glass substrate using a sol-gel method. The synthesized nanorods were
postannealed at 150, 350, and 500∘ C. The surface morphologies of Sn-doped ZnO nanorods at different ...
Functionalization of Si Nanowire Surfaces to Create Interactive Mechanism for Heavy Metals Detection Application
(IOP Publishing, 2018)
Silicon (Si) nanostructure was prepared using a cheap and in-house technique. The device was fabricated via dry oxide etching approach with a controlled oxygen flow rate in an oxidation furnace, a network of uniform Si ...
Arsenic ion Detection via Electron Chemical Reaction Mechanism Based on Interdigitated Electrode (IDE)
(IOP Publishing, 2018)
In recent days, both raw and treated water being consumed by human and animal posed serious threat to the consumer. Due to heavy industrialization water easily carries heavy metals that are harmful to consumers. Heavy metal ...
Mercaptopropyltriethoxysilane (MPTES) Concentration Effect on Selectivity and Electrical Response of Nanostructure
(IOP Publishing, 2018)
The surface modification by on Mercaptopropyltriethoxysilane (MPTES) done to enhance electrical behavior of nano-IDE -based sensor, silicon based active area was coated with MPTES. The electrical properties of modified ...
