Transparent conductive glasses such as thin film transistor (TFT) array and colour filter glasses were recovered from the TFT-liquid crystal display panel wastes by dismantling and sonic cleaning. Noble metals (i.e. platinum (Pt)) and indium tin oxide (ITO) are generally used in the cathode of a dye-sensitized solar cell (DSSC). To reduce the DSSC cost, Pt was replaced with nano nickel-encapsulated carbon-shell (Ni@C) nanoparticles, which were prepared by carbonization of Ni²⁺-β-cyclodextrin at 673 K for 2 h. The recovered conductive glasses were used in the DSSC electrodes in the substitution of relatively expensive ITO. Interestingly, the efficiency of the DSSC having the Ni@C-coated cathode is as high as 2.54%. Moreover, the cost of the DSSC using the recovered materials can be reduced by at least 24%.
ABSTRACT:The key contribution to the legislation of heritage preservation in Taiwan primarily derived from the historical monument movements in the 1970s. Specific legislation results include the establishment of Council for Cultural Affairs and the implementation of the Cultural Heritage Preservation Act in 1982. Although the Cultural Heritage Preservation Act is the first subjective cultural act, its lack of structure during the initial commencement stages made it un-conducive to heritage preservation and thus unable to meet the people's expectations. Therefore, throughout the 33 years after the implementation of the Cultural Heritage Preservation Act, the Act has been amended 6 times. These amendments reflect the degree of importance that the society has attached to heritage preservation, and the innovative system also showcases the progress in preservation concepts and methods. These innovative orientations, such as emphasizing on the authenticity and integrity of heritage preservation, intangible cultural heritage, and cultural diversity, conform to the international preservation trends. They are also local trends such as encouraging community participation, adaptive-reuse, or enhancing the local governments' powers to implement local cultural governance. This is particularly true for the fifth comprehensive revision in 2005, which has symbolic significance because its contents epitomized the heritage preservation work while moving Taiwan's heritage preservation system towards globalization and localization. Therefore, we analyzed the Cultural Heritage Preservation Act amendment and revision processes over the past 33 years to highlight the innovations in Taiwan's cultural heritage work and illustrate their globalization and localization features. Finally, we proposed recommendations for Taiwan's preservation work in the future as the Cultural Heritage Preservation Act is about to undergo its seventh amendment in 2015.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
