Problematising the genesis of the Korean Wave in Taiwan, the paper proposes to see it as the product of social and political forces pertaining to a specific moment of history of Taiwan. Other than deeming the genesis categorically as a cultural instance, it argues that the Wave is in effect the production manufactured at the convergence of social political changes at a historical moment unprecedented in Taiwan history. To respond to the new social and political conditions, the Korean Wave is deliberately appropriated as the extension of social institution and political control for the purpose of prolonging class interests of the traditional rulers. By means of mammoth circulation and transmission of print media and television broadcast, the Wave is immediately called into being and captivates a throng of Taiwan Residents audience. In return, the overwhelming popularity of Korean TV dramas is capitalized on politically besides socially and culturally in order to meet new needs. Resiting the Korean Wave in Taiwan in the social and political processes at the specific moment of Taiwan history, its genesis is thereby complicated and overdetermined on top of the advanced and promised drama qualities and productions. Inevitably a limited view, however, the paper is hoped to provide an alternative aspect to the studies of the Korean Wave either in Taiwan or other regions.展开更多

In this work the disk-structured triboelectric nanogenerator （TENG） was prepared based on the mature printed drcuit board （PCB） technology and the composite structure for effectively improving the utilization in space. A narrow grating of 1~ was designed to produce high output. Operated at a rotation rate of 1,000 rpm, the TENG produces a high output power density of 267 mW/cm2 （total power output of 25.7 W） at a matched load of 0.93 MfZ After introducing a transformer, the output power can be managed so that it can be directly used to charge a battery for a smart phone. With the PCB production technology, fabrication of high performance TENG at low cost and large-scale becomes feasible.展开更多

In terms of scalability and cost efficiency, inkjet printing is very competitive over other existing direct- writing methods. However, it has been challenging to obtain highly stable and clog-free graphene-based ink. Here, we report an alternative and highly efficient technique to directly print a reducing reagent on graphene oxide film to form conductive graphene patterns. By this ＂inkjet reduction＂ method, without using any other microfabrication technique, conductive graphene patterns and devices for various applications are obtained. The ionic nature of the reductant ink makes it clog-free and stable for continuous and large-area printing. The method shows self-limited reduction feature, which enables electrical conductivity of graphene patterns to be tuned within 5 orders of magnitude, reaching as high as 8,000 S.m-1. Furthermore, this method can be extended to produce noble metal/graphene composite patterns. The devices, including transistors, biosensors, and surface- enhanced Raman scattering substrates, demonstrate excellent functionalities. This work provides a new strategy to prepare large-area graphene-based devices that is low-cost and highly efficient, promising to advance research on graphene- based flexible electronics.展开更多
