Journal ArticleDOI
Roll-to-roll production of 30-inch graphene films for transparent electrodes
Sukang Bae,Hyeongkeun Kim,Youngbin Lee,Xiangfan Xu,Jaesung Park,Yi Zheng,Jayakumar Balakrishnan,Tian Lei,Hye Ri Kim,Young Il Song,Young Jin Kim,Kwang S. Kim,Barbaros Özyilmaz,Jong Hyun Ahn,Byung Hee Hong,Sumio Iijima,Sumio Iijima +16 more
TL;DR: The roll-to-roll production and wet-chemical doping of predominantly monolayer 30-inch graphene films grown by chemical vapour deposition onto flexible copper substrates are reported, showing high quality and sheet resistances superior to commercial transparent electrodes such as indium tin oxides.
Journal ArticleDOI
Graphene for Controlled and Accelerated Osteogenic Differentiation of Human Mesenchymal Stem Cells
Tapas R. Nayak,Henrik Andersen,Venkata S. Makam,Clement Khaw,Sukang Bae,Xiangfan Xu,Pui Lai Rachel Ee,Jong Hyun Ahn,Byung Hee Hong,Giorgia Pastorin,Giorgia Pastorin,Barbaros Özyilmaz,Barbaros Özyilmaz +12 more
TL;DR: It is shown that graphene provides a promising biocompatible scaffold that does not hamper the proliferation of human mesenchymal stem cells and accelerates their specific differentiation into bone cells, demonstrating graphene's potential for stem cell research.
Journal ArticleDOI
Length-dependent thermal conductivity in suspended single-layer graphene.
Xiangfan Xu,Luiz Felipe C. Pereira,Yu Wang,Jing Wu,Kaiwen Zhang,Xiangming Zhao,Sukang Bae,Cong Tinh Bui,Rongguo Xie,John T. L. Thong,Byung Hee Hong,Kian Ping Loh,Davide Donadio,Baowen Li,Barbaros Özyilmaz +14 more
TL;DR: Interestingly and in contrast to bulk materials, at 300 K, thermal conductivity keeps increasing and remains logarithmically divergent with sample length even for sample lengths much larger than the average phonon mean free path, which provides fundamental understanding of thermal transport in two-dimensional materials.
Journal ArticleDOI
Electrochemical Delamination of CVD-Grown Graphene Film: Toward the Recyclable Use of Copper Catalyst
TL;DR: This work demonstrates a highly efficient, nondestructive electrochemical route for the delamination of CVD graphene film from metal surfaces, which affords the advantages of high efficiency, low-cost recyclability, and minimal use of etching chemicals.
Journal ArticleDOI
Thorium-doping–induced superconductivity up to 56 K in Gd1−xThxFeAsO
Cao Wang,Linjun Li,Shun Chi,Zengwei Zhu,Zhi Ren,Yuke Li,Yuetao Wang,Xiao Lin,Yongkang Luo,Shuai Jiang,Xiangfan Xu,Guanghan Cao,Zhu-An Xu +12 more
TL;DR: In this article, instead of F- substitution for O2-, the authors employed Th4+ doping in GdFeAsO with the consideration of "lattice match" between Gd2O2 layers and Fe2As2 ones.
