SELF-ASSEMBLY OF GOLD NANORODS ON WRINKLED TEMPLATE
YUJIA LIANG,QIAN LIU,YONG XIE,ZHENING ZHU,YINGLU JI,XIAOCHUN WU 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2014 NANO Vol.9 No.7
Self-assembly of nanoparticles has attracted more attention in the last decade due to theirpotential applications in many ¯elds, such as sensors, surface-enhanced Raman scattering (SERS)substrate and optical/plasmonic components. Wrinkles, as one kind of common natural surface,are used to be a template/substrate in micro°uidic sieves and solar cells. In this work, a wrinkledtemplate with depth of about 200 nm and period of 1.64 ? m is used for modulating the self-assemblyprocess of gold nanorods (GNRs) to obtain patterned self-assemblies for potential application. Inorder to fully re°ect the role of the wrinkled template in the self-assembly, the templates are placeduprightly in the GNRs solution to intensify the interplay between the wrinkled surface andnanorods. The self-assembly process is carried out in a climate chamber, where the temperatureand humidity can be controlled programmingly to modulate the self-assembly conditions. Theexperimental results show that for the ¯xed wrinkled template, an obvious e®ect on the self-assembly is at the temperature range from 30?C to 50?C. Nematic, curved (mostly are end-to-end)and transition mode can be obtained. According to humidity, GNRs tend to form the nematicfashion in humidity lower than 60%, and the curved fashion in a higher humidity.

Recyclable One-Step Extraction and Characterization of Intact Melanin from Alpaca Fibers
Yujia Liang,Qi Han,Nolene Byrne,Lu Sun,Xungai Wang 한국섬유공학회 2018 Fibers and polymers Vol.19 No.8
Melanin, a ubiquitous natural pigment, has attracted much attention in energy and nanotechnology areas in recent years. With the increasing demand for high-quality melanin materials and sustainable experimental environment, this study was conducted to achieve melanin with intact structure through recyclable extraction method using ionic liquid (IL). Melanin extracted from base dissolution and acid isolation (BA) method and acid hydrolysis (AH) method were also used for comparison. SEM and 13C-NMR characterizations indicated that IL treatment has retained the original structure of melanin while other methods caused particle damage to various degrees. In addition, the recycled IL (up to five times) showed good reproducibility, and the performance of extracted melanin at the 5th cycle was well-maintained.
