Environmental and awareness: single axis solar tracking system / Muhammad Emi Azmel Shohini and Azri Ayoub Izaruddin
No full textPhotovoltaic panel is suitable alternative way to generate electricity is Malaysia because most of its location receives large number of solar radiation throughoift the year. However the regular PV panel is implemented on a fix place bitt the poshion of sun in the sky changes with the seasons and time of the day . Since the maximum point of received energy is reached when the directions of solar radiation is directly perpendicular on the panel surface, therefore the conversion energy on the PV panel does not efficient. Thus an increase of the output energy of a given PV panel can be obtained by mounting the panel on a solar tracking device that follows the sunlight direction. The objective of this pngect is to develop automatic solar tracking system whereby the system will caused PV panel keep align with the direction of sunlight from sun rise until sunset in order to maximize energy conversion. The system focuses on the controller circuit in which it will caused the system is able to track the maximum intensity of sunligh
Silicon Nanowires Based DNA Biosensor
No full textProf. Dr. Uda Hashim and his team won bronze at Malaysia Technology Expo 2010 (MTE 2010), 4th - 6th February 2010 at Putra World Trade Centre (PWTC), Kuala Lumpur. MTE 2010 organized by MARS and PROTEMP Exhibitions Sdn. Bhd.This research describes the fabrication of silicon nanowire for DNA hybridization detection in biosensor application. The SiNWs are fabricated by electron beam lithography and followed by deposition of contact metals. Aurum is a suitable metal to make Ohmic contact with SiNWs and its exhibit electrical transport measurements of the devices. The presence of the hybridization DNA will induce electronic charge and changed the electronic properties of the devices from which detectable electronic signals are generated
Nanogap Dielectric Capacitor for Label Free Bio-Molecules Detection
No full textProf. Dr. Uda Hashim and his team won silver at 21st International Invention, Innovation and Technology Exhibition (ITEX) 2010, 14th - 16th May 2010 at Kuala Lumpur Convention Centre (KLCC), Kuala Lumpur, Malaysia.This research demonstrating that nanogap biosensor was fabricated by standard CMOS technologies function as extremely sensitive and selective biosensor for biomolecular detection and medical diagnostic application using label-free detection technique. The difference in dielectric properties between single-stranded DNA (ssDNA) and double-stranded DNA (dsDNA) permits use of capacitance measurements to detect DNA hybridization which is time saving and cost effective
