THE PHYSICS DREAM

Khairol Annuar Bin Zaini

I am a PhD student (Photonics Engineering) in the
department of Physics, Faculty of Science, Universiti
Malaya. I am under the supervision of Ir. Dr. Lim Kok
Sing and Distinguished Prof. Datuk Dr. Harith
Ahmad. Due to their expertise in this field, I am
proud and grateful to be a student under their
guidance. Our lab is mainly focused on signal
processing and fibre Bragg grating (FBG) sensor
under Photonics Research Centre. I am working on
the application of FBG towards sensing application
and optical communication system. FBG technology
is among the popular choices for optical fibre
sensors especially for strain and temperature
measurements because of its compact size,
immunity to interference from electrostatic and SILVER MEDAL: International Research Innovation

many advantages compared to conventional (International)
electrical sensors.

Surender Gunalan
I am a postgraduate student (MSc. Material Science) in the
department of Physics, Faculty of Science, Universiti Malaya. I am
glad to have supervisors like Professor Dr. Ramesh T Subramaniam
and Associate Professor Dr. Ramesh Kasi. Our lab is called the
Materials for Energy Applications Laboratory (M.E.A.L) under the
Centre for Ionics-University of Malaya (C.I.U.M). I am working on
energy storage devices specifically on supercapattery. This is an
energy storage device with the combination of battery type and
capacitive electrodes. Since the device has two different electrodes,
it will show two different properties during applications. Redox and
electrostatic reactions occur simultaneously in a single device. The
supercapattery has better energy and power densities as well as
prolonged lifecycle compared to either supercapacitor or battery. It
may be applied in flexible electronics and smart vehicles in the
future. Our team works on energy storage devices (supercapattery
& supercapacitors), energy conversion devices (dye sensitized solar
cell) and electrolytes (hydrogel & polymer electrolytes).
