TL;DR: By combining the attributes of photosensitive ZnO nanorods and highly conductive graphene, this work demonstrates a highly sensitive visible-blind ultraviolet (UV) sensor based on graphene related heterostructure for the first time.
Abstract: The weak photon absorption and fast carrier kinetics of graphene limit its application in photodetection. This limitation can be overcome by introducing photosensitive nanostructures to graphene. Herein we report the synthesis of a ZnO nanorod/graphene heterostructure by a facile in situ solution growth method. By combining the attributes of photosensitive ZnO nanorods and highly conductive graphene, we for the first time demonstrate a highly sensitive visible-blind ultraviolet (UV) sensor based on graphene related heterostructure. The photoresponsibility of the UV sensor can reach 22.7 A W(-1), which is over 45,000 fold higher than that of single graphene sheet based photodetectors.

TL;DR: A detailed investigation on the performance of three advanced modulation formats for 100 Gb/s short reach transmission system, PAM-4, CAP-16 and DMT, and a comparison of computational complexity of DSP for the three formats is presented.
Abstract: Advanced modulation formats combined with digital signal processing and direct detection is a promising way to realize high capacity, low cost and power efficient short reach optical transmission system. In this paper, we present a detailed investigation on the performance of three advanced modulation formats for 100 Gb/s short reach transmission system. They are PAM-4, CAP-16 and DMT. The detailed digital signal processing required for each modulation format is presented. Comprehensive simulations are carried out to evaluate the performance of each modulation format in terms of received optical power, transmitter bandwidth, relative intensity noise and thermal noise. The performance of each modulation format is also experimentally studied. To the best of our knowledge, we report the first demonstration of a 112 Gb/s transmission over 10km of SSMF employing single band CAP-16 with EML. Finally, a comparison of computational complexity of DSP for the three formats is presented.

TL;DR: A PCA/APCS model was applied to the data on non-methane hydrocarbons measured from January to December 2001 at two sampling sites in Hong Kong and found that vehicle emissions and LPG or natural gas leakage were the main sources of C(3)-C(5) alkanes and C( 3-C( 5) alkenes while aromatics were predominantly released from paints.
