Three research papers contributed by the Department of Applied Physics of PolyU were recently published in the Nature series journals:

(a) Optoelectronic resistive random-access memory (ORRAM) for neuromorphic vision sensors – “Nature Nanotechnology”

 Dr Chai Yang, Associate Professor, and his team developed an optoelectronic device that mimics the functions of human retina in image sensing, memorisation, and pre-processing, with image recognition rate and efficiency exceeding existing artificial visual systems. It offers promising contribution towards the development of applications in edge computing and Internet of Things.


(b) Continuous artificial synthesis of glucose precursor using enzyme-immobilised microfluidic reactors – “Nature Communications”

Dr Zhang Xuming, Associate Professor, and his team discovered technology to replicate the opto-fluidic system of leave vein to create micro-reactors for conducting the first phase reaction of CO2 fixation in natural photosynthesis. The innovation contributes to artificial photosynthesis developments and will help relieve food crisis and produce biofuel.


(c) Enhanced sieving from exfoliated MoS2 membranes via covalent funcationalisation – “Nature Materials”

Dr Nicolas Onofrio, Assistant Professor, and his team developed a nanolaminate membrane based on covalently functionalised molybdenum disulfide (MoS2) nanosheets. The control of the surface chemistry of exfoliated 2-dimensional (2D) materials allows further exploration of the nanofluidic phenomena inside nanolaminate membranes at fundamental and practical levels for water purification or osmotic energy.

Prof Daniel Lau, Head of the Department of Applied Physics, takes pride in the contributions of the three researchers and said, “the Department will continue to devote its efforts in the pursuit of excellence in teaching and research”.

Prof. Alex Wai, Vice President (Research Development) of PolyU, said, “PolyU has been undertaking cutting-edge research that delivers real impact to academia and to the world. We are committed to nurturing our academics and researchers to collaborate locally and internationally in fundamental and translational research. We are very pleased that their research findings were published in prestigious and world-renowned journals.” (Sing Tao Daily F01, Sky Post P16)
