Electrical Power Determination of the diameter of carbon steel pipes which will provide a safe clearance (point of no eddy current) around electricity carrying cables suspended within them with spaced insulators The overall aim of this research is to eventually enable electric power transmission from Sarawak to Semanjung Malaysia.  630 km separates Sarawak with her vast hydroelectric potential and Semanjung Malaysia which depends mostly on gas for electric power. Undersea XLPE (cross linked polyurethane) cables have been deemed impossible after a study by Sarawak Energy Berhad (SEB) because of the large capacitance loss.  Also the cost of the previously proposed undersea cable between Sarawak and Semanjung Malaysia was equivalent to the cost of a Bakun dam. As a comparison of current carrying capacity of undersea cables versus bare overhead cables, the longest undersea power cable in the world so far is 580 km, 450kV, 700MW XLPE HVDC cable between Norway and Netherlands.  While the longest bare overhead line is the 2,385 km, 600kV, 7.1GW HVDC Rio Madeira transmission link in Brazil.  A close second is the 2,090 km, 800kV, 7.2GW HVDC Jinping-Sunan transmission link in China. Therefore cables with insulation surrounding them are far less capable than bare overhead cables.  Thus if cables can be laid undersea just like bare overhead lines, the furthest points in Malaysia, that is  Lahad Datu to Pulau Langkawi (a distance of 2,219 km) can be connected.  Added to the above statistics, underground cables fail much more often than overhead cables and the overall cost of underground cables is up to 400% higher than bare overhead cables.This research envisages HV (High Voltage) cables straddled with spaced ceramic or plastic insulators at the center of pipes from Lundu, Sarawak all the way to Johor.  But pipes around conductors will generate eddy currents and thereby waste energy as heat.  This research will study the safe clearance between bare copper electric cables and carbon steel pipes such that there is no eddy current loss.  GIL(Gas Insulated Lines) which was developed by Siemens is a similar idea but with a focus to achieve maximum transfer of electric power.  GIL uses SF6 (Sulfur Hexafluoride) which is ranked as the most potent Greenhouse gases.  GIL uses aluminum while this research proposes carbon steel pipes which the oil and gas industry of Malaysia already has an expertise in.

Electrical Power Switch gear switching safety device There have been many fatalities for people performing switching of high voltage switchgears.  Therefore there is a need for an automation which is easily transported and moved to site to enable switching personnel perform switching from a distance away from the switchgear. Most fatalities upon investigation are caused by gross neglect by the switching personnel or by the last person who handled the switchgears.  For the former case there was one incident in SEB (Sarawak Energy Berhad) in 2014 where a SEB staff saw that the oil level in the switchgear was low but presumed that it was enough to switch the switchgear safely.  The switchgear exploded and the personnel had second degree burns.  For the latter case in Semanjung Malaysia, four staff of TNB (Tenaga National Berhad) were killed as an 11kV switchgear exploded; the root cause was discovered to be a fuse jumped with a copper wire by the last switching personnel.

NanoICs Synthesis of Ultra Low Power Fast Adders Using Reversible Logic. This research takes on a formidable question as to what is the next generation of digital systems as technology shrinks to nanoscale. Obviously the most anticipated area of discussion is ultra-low power devices that could function at very low power and could sustain with the energy harvested from RF and other sources. In view of these requirements, this project aims in designing high speed ultra low power arithmetic circuits using reversible logic to be used in DSP and multimedia processors.

Nanomaterials Fabrication and Characterization of nanostructured CdTe/CdS Thin-Film Solar Photovoltas (PV) Photovoltaic (PV) solar energy conversion is an attractive method for clean energy generation. PV technology comes at the top of the renewable energy as a whole and therefore worldwide research is continuing to develop low-cost high-efficiency solar panels. The biggest challenge posed in any form of solar cells if the efficiency of energy conversion. Due to involvement of industry, lab-scale efficiency has rapidly improved from 16.5% in 2001 to 20.4% within the last few years. The aim of this research is to fabricate and characterize the electrodeposition of CdTe/CdS on FTO/ITO substrate and to analyze the morphological, structural, optical and the electrical characterization of the CdTe/CdS structure and the effect of molar concentration of CdSO4 and TeO2 solutions on CdTe thin film with the intension of improving the optical absorption efficiency further.

Low Power Embedded Systems Ultra Low-Power FPGA based wireless sensor node with customized event-based Architecture for Biomedical Applications. Wireless sensor network (WSN) have been emerging rapidly in recent times. WSN could monitor cardio-respitory rhythm,, pulse oximetry, body temperature, arterial pressure, ECG or EEG, depending on the clinical scenario. Ultra-low power Wireless Sensors (WS) typically consists of (i) sensors, (ii) energy harvesting transducers, (iii) a radio link and a microcontroller. To, minimize the power wastage , the microcontroller is designed as event based which means, the processor starts its data processing and driving its output only at desired time and hibernates when there is no event.

Functional Nanomaterials Synthesis of different functional nanomaterials, such as metal nanoparticles, metal oxide nanowires and carbon nanotubes for a range of applications including physical, chemical and environmental sensors, energy scavenging materials, low-cost transparent conductors and optoelectronic devices Materials with physical dimensions reduced to the nanoscale (less than 100 nm) can exhibit markedly different properties compared to those on larger length-scales. This is mainly a result of the massively increased fraction of atoms that are at the surface of the material or the confinement of charge carriers on length scales similar to their quantum mechanical wavelength.  
Much of the interest in nanotechnology stems from these unique quantum and surface phenomena that matter exhibits at the nanoscale. As the majority of the atoms in these nanostructures are a short distance from the surface, the optical and electrical properties of these systems can be strongly modified by changes in their environment, allowing a host of applications particularly in sensing.
    In recent years the techniques for growing and fabricating nanoscale materials have matured significantly, to the point where researchers are able to tailor their properties toward particular applications, allowing the production of truly functional nanomaterials, which utilize these properties and allow the fabrication of range of new and exciting technologies.
