Research Interest: Although my UG background is in civil engineering, I was always interested in applying a civil engineering related research topic to environmental solutions. My project here involves development of an anti-fouling, anti-biofouling coating for marine structures. Antifouling has been an issue since the first boats were launched over several thousands of years ago. It is still an issue. Superhydrophobic surfaces in particular has been a hot area recently and we are exploring several novel applications of them.

Research Interest: My thesis work centered on developing a slab waveguide with porous silicon substrate coated with zinc oxide. The first part of the research involved fabrication and characterization of the porous silicon substrate by anodizing in hydrofluoric acid. Correlations were made between the porosity of the silicon surface and its refractive index. The Bruggeman Effective Medium Theory was used to simulate the refractive index of the porous layers. As expected, refractive index decreased with increased porosity. Patterned color bands corresponding to variable porosity due to synthesis conditions within the electrolytic cell proved to be an interesting phenomenon that warrants further study.

Hazil Rafis Bin Abdul Rahim
Country of Origin: Malaysia.


Affiliation :Department of Electrical Engineering, Faculty of Engineering and Photonics Research Centre, University of Malaya, Kual Lumpur, Malaysia. Visiting AIT from the University of Malaysia through Bangkok University in Thailand
Length of Stay :July 2015 through February 2016
Research Interest: Light side coupling of ZnO nanorod coatings with plastic optical fibers (POFs) for sensing humidity and alcohol vapors. ZnO micro-nanorods grown on spiral patterned POFs to eliminate backscattering and leakage showed enhanced output voltage than bare fibers or fibers coated with ZnO without the helical pattern. They, along with Dr. Waleed S. Mohammed of Bangkok University, were the first to demonstrate side coupling of light for the purposes of creating an inexpensive detector that utilizes broadband light sources. Summary: Rafis is a Ph.D. student at the University of Malaya. Rafis has been incredibly productive by submitting three papers. He and his family enjoyed life in Thailand while contributing his research efforts to both Bangkok University and AIT.

Muhammad Q. Lokman
Country of Origin: Malaysia.


Affiliation :Department of Electrical Engineering, Faculty of Engineering and Photonics Research Centre, University of Malaya, Kuala Lumpur, Malaysia. Visiting AIT from the University of Malaysia through Bangkok University in Thailand
Length of Stay : 6+ months
Research Interest: Light backscattering (e.g. reflectance) by zinc oxide micro-nanorods on tips of plastic optical fibers with application for humidity and alcohol vapor sensing. Relative humidity and alcohol vapor sensing by light backscattering was demonstrated using ZnO micro-nanorods grown on the tips of plastic optical fiber (POF). Synthesis of ZnO micro-nanostructures was accomplished by the hydrothermal method. A novel technique is proposed herein to extract the backscattered light by ZnO micro-nanostructures. The system was shown experimentally to sense moisture and alcohol vapors. Three ranges of the visible spectrum - blue (400 - 450 nm), green (500 - 570 nm) and red (610 - 700 nm) - were studied in experiments. Spectral reflectance based on backscattering from ZnO surface structures was used to measure the amount of light backscattered by ZnO nanorods. Results showed that light in the red visible range of the spectrum had higher sensitivity and reflectivity compared to blue and green spectral ranges.

Research Interest: Adaptation of silica nanoparticles as vehicles for NPK fertilizer delivery. Silica nanoparticles of size ranging form 30 nm to greater than 100 nm were coated with chitsan glucosamine porous layers. Following coating, NPK commercially available fertilizers were allowed to impregnate the layers. We hope to adapt this method in filed studies later on. Nanoscale vehicles for fertilizer deliver offer an efficient and time released method of providing fertilizer for regions in which harsh conditions exist.

Testimonial: I am very grateful for COEN for allowing me to work in their laboratory as a visiting scholar. All my needs were taken care of including chemicals required, equipment and facilities. The accommodations at AIT were very confortable and convenient. I recommend other students to join this laboratory - even if for a short time.

Advisor: S. Manjunath
Lenght of stay: December 2014 - July 2015
Research Interest: We present an investigation of ZnO nanorods for their light guiding ability. ZnO nanorod waveguides (100 µm w x 2.5 µm h x 1mm l) were grown on a seeded glass substrate template using hydrothermal process at 90°C. Modification of the substrate surface in order to obtain densely ordered nanorods induced selective growth. ZnO nanorods were characterized by scanning electron microscopy (SEM). The guiding property, i.e. locally excited photoluminescence propagation along the length of the waveguide, was analyzed with an image-processing program. Following application of a fiber optic white light source on the ZnO nanostructure, we found that light propagation occurred within the glass substrate. No such propagation occurred if light was applied on uncoated areas of the glass. Modeling of waveguide behavior to determine the number of transverse electric (TE) and transverse magnetic (TM) modes was exercised using a finite element method (FEM) solver.

Research Interest: The topic was centered on mathematical modeling and study of nonlinear switching in optical fiber Bragg gratings (FBG) by a transfer matrix method. Critical parameters contributing to high performance nonlinear fiber Bragg grating were studied. The transmission spectrum centered at 1550 nm was analyzed with varying number of layers and refractive-indices. The study showed that by proper modification in grating length of the FBG, we were able to optimize transmission spectrum for required application. The nonlinear behavior of FBGs can be further applied in optical switching applications (all-optical logic gates).

Research Interest: Comparison of different zinc stannate structures synthesized at room temperature for photodegradation of dyes and phenol. Aqueous synthesis was used to obtain zinc stannate (ZTO) nanoparticles by precipitation at room temperature. Pourbaix diagrams were employed to formulate the precipitation reactions and synthesis process. Solution pH was controlled during the synthesis process as a major variable. The synthesized ZTO particles showed good photocatalytic activity under UV light irradiation. In order to improve visible light photocatalytic activity of ZTO nanoparticles, mixed phase zinc stannate/zinc oxide (ZnO) composites were prepared by co-precipitation at room temperature. Effects of precursor concentrations on the size and morphology of the obtained particles are reported. The composite ZTO/ZnO showed better photodegradation under visible light irradiation compared to ZTO and ZnO nanoparticles with methylene blue (MB) as a test chemical contaminant. Experiments were designed to elaborate on the active species for photocatalytic degradation of the dye and are reported here. Benzoquinone (BQ) was found to be the most effective scavenger, reducing the photodegradation considerably, indicating that O2 -- plays a major role in MB degradation since 50% reduction in photocatalytic activity was observed.

Testimonial: After completing my Ph.D. from the Asian Institute of Technology, I have rejoined my parent institute in Quetta, Pakistan where I am an assistant professor in chemical engineering. I have made many friends in our nano family. It was my home away from home for many years.

Research Interest : Gas sensors have been widely used in many applications including environmental monitoring, industrial control, and detection in warfare or for averting security threats. High sensitivity, selectivity, and fast response time are required for application in real-time monitoring and detection of toxic gases. Single-walled carbon nanotubes (SWCNTs) provide large specific surface area beneficial for gas adsorption thereby increasing sensor sensitivity. In this paper, ammonia (NH3 ) gas sensors based on SWCNTs were developed using interdigitated silver electrodes printed with nanoparticulate ink on alumina substrates. Simple and inexpensive methods including shaking and dispersion in appropriate solvents were used to debundle SWCNTs for improving sensor response. The fabricated sensors showed a maximum response of 27.3% for 500 ppm NH3 at room temperature. Detection limit of the sensor devices at room temperature were estimated to be - 3 ppm.

Testimonial :
: I started the Master’s program in Nanotechnology at the Asian Institute of Technology (AIT), Bangkok in 2009. My thesis involved the fabrication of carbon nanotube based ammonia gas sensors. I completed my Master's degree in 2011 and received the Franco-Thai scholarship program to pursue my PhD in the same year. I did my PhD in the NanoBioSystems (NBS) group at the Laboratoire d'Analyse et d'Architecture des Systèmes (LAAS-CNRS), Toulouse. My PhD research was focused on the development of fluorescence-based nanofluidic biosensor platform for real-time measurements of protein binding kinetics. I completed my PhD in 2015 from the Université; Toulouse III - Paul Sabatier with two patents (filed in US and France). My research interests include chemical and biological sensors, micro/nanofluidics and lab-on-a-chip based technology. I am currently seeking employment opportunities in the field of nano and microtechnology in industry.
