//Greetings everyone, my name is Beh Khi Poay, a senior lecturer in School of Physics, USM. // This is the second time i revisit this site to update my profile, so stay tune for more! [UNDER CONSTRUCTION, apologies if some words or phrase you find inappropriate, do let me know, thanks] Greetings everyone, my name is Beh Khi Poay, name (名): 马棋培. Some history about myself: BSc (2006 - 209); PhD (2010 - 2015), at School of Physics, Universiti Sains Malaysia I'm formerly a USM student, did both my BSc and PhD here (I skipped MSc, not trying to flex but this did happened). During my undergraduate years, I'm from the Engineering Physics Programme, now rebranded as "Optics and Photonics Track". I did not take minor hence, I have to go with the elective courses. During my PhD years, my field of research is Solid State Physics, and my thesis title was "Fabrication and Investigation of GaN Nanostructures and Their Applications in Ammonia Gas Sensing". Secondary School: SMJK (C) Chung Ling Believe it or not, my secondary school is CLHS. I did my Form 1 to Form 6 there. Where am I? I'm working as a lecturer in School of Physics, Universiti Sains Malaysia. Research Areas (TLDR version) My research is more on nanomaterials synthesis. What kind of nanomaterials? I've work on Gallium Nitride (GaN) nanowires, porous GaN (my main PhD work), porous alumina (Al2O3), titanium dioxide (TiO2) nanotubes. In recent years I'm moving towards graphene materials (which includes graphene oxide and reduced graphene oxide) synthesis. Due to application interest, I learn some nanoparticles (silver and copper) synthesis. So I do have some nanomaterials there, but what about applications? For applications, the typical ones would be sensors, e.g. UV photo detectors (GaN, TiO2), gas sensors. I'm currently attempting to go for electrochemical sensors that can sense change in pH, heavy metal ions, and glucose. There maybe other things to sense once I get to know more about the sensors. Other skills (some are learnt to support my research work; TLDR) operating FESEM - learnt to operate, not to fix. Electronics - building tools such as power supplies (with Arduino integration) for electrochemical based experiments. I'm still learning every now and then, and my "creations" is akin to a reflection of what I have learn. So dont expect high tech stuff that rival the market. Learning to build is important as some tools are very niche until is not worth spending much to get them. Additionally, expanding your knowledge is key to life-long learning. 3D drawing, printing - what would you do when you own a 3D printer, and what makes you desire to have a 3D printer? I'm still learning about 3D drawing (aside using Tinkercad, I've invested my time on FreeCaD. The latter would be more dynamic and accessible by all people, including our students, as it is "Free"). Currently I did 3D printing was to improve my experiment setup so that it will be more user friendly (can you imaging wanted to have a floting pairs of crocodile clips as drawn in diagrams but only to realize gravity is slapping you back to reality?). For now i can design simple enclosures, but I do interested in making hinges (some movable parts) and other interesting mechanisms. Profile
