Bismuth Sulfide Nanoflowers for Detection of X-rays in the Mammographic Energy Range
Yeow, John; Osei, Ernest K; Nambiar, Shruti (Nature, 2015-03-24)The increased use of diagnostic x-rays, especially in the field of medical radiology, has necessitated a significant demand for high resolution, real-time radiation detectors. In this regard, the photoresponse of bismuth ... -
A flexible, scalable, and self-powered mid-infrared detector based on transparent PEDOT: PSS/graphene composite
Zhang, Mingyu; Yeow, John (Elsevier, 2020-01)A flexible, self-powered and semi-transparent mid-infrared photodetector is demonstrated with graphene and poly(3,4-ethylenedioxythiophene): poly(4-styrenesulfonate) (PEDOT: PSS) composite on poly vinyl alcohol (PVA) ... -
Self-powered on-line ion concentration monitor in water transportation driven by triboelectric nanogenerator
Chen, Chen; Wen, Zhen; Wei, Aimin; Xie, Xinkai; Zhai, Ningning; Wei, Xuelian; Peng, Mingfa; Liu, Yina; Sun, Xuhui; Yeow, John (Elsevier, 2019-08)Ion concentration in water is a key criterion for evaluating water quality. In this work, we developed a self-powered on-line ion concentration monitor in water transportation based on impedance matching effect of triboelectric ...
