UV/Ozone-Oxidized Large-Scale Graphene Platform with Large Chemical Enhancement in Surface-Enhanced Raman Scattering
TL;DR: The enhancement factors were increased from ∼10(3) before ozone treatment to 10(4), which is the largest chemical enhancement factor ever on graphene, after 5 min ozone treatment due to both high oxidation and p-doping effects on graphene surface.
Journal ArticleDOI
Single-Gate Bandgap Opening of Bilayer Graphene by Dual Molecular Doping
Jaesung Park,Sae Byeok Jo,Young-Jun Yu,Young-Jun Yu,Youngsoo Kim,Jae Won Yang,Wi Hyoung Lee,Hyun Ho Kim,Byung Hee Hong,Byung Hee Hong,Philip Kim,Kilwon Cho,Kwang S. Kim +12 more
TL;DR: This work unambiguously proves that it is possible to open a bandgap with two molecular dopants (F4-TCNQ and NH2 -functionalized self-assembled monolayers (SAMs) even in a single-gate device structure.
Journal ArticleDOI
Piezoelectric-Driven Self-Charging Supercapacitor Power Cell
Ananthakumar Ramadoss,Balasubramaniam Saravanakumar,Seung Woo Lee,Youngsoo Kim,Sang-Jae Kim,Zhong Lin Wang +5 more
TL;DR: This work fabricated a piezoelectric-driven self-charging supercapacitor power cell (SCSPC) using MnO2 nanowires as positive and negative electrodes and a polyvinylidene difluoride-ZnO film as a separator, which directly converts mechanical energy into electrochemical energy.
Journal ArticleDOI
Fast synthesis of high-performance graphene films by hydrogen-free rapid thermal chemical vapor deposition.
Jaechul Ryu,Youngsoo Kim,Dong-kwan Won,Nayoung Kim,Jin-Sung Park,Eun-Kyu Lee,Don-Yeop Cho,Sung-Pyo Cho,Sang Jin Kim,Gyeong Hee Ryu,Hae A. Seul Shin,Zonghoon Lee,Byung Hee Hong,Seungmin Cho +13 more
TL;DR: In this article, mass-produced graphene films synthesized by hydrogen-free rapid thermal chemical vapor deposition (RT-CVD), roll-to-roll etching, and transfer methods were reported.
Journal ArticleDOI
In vitro trans-differentiation of rat mesenchymal cells into insulin-producing cells by rat pancreatic extract.
TL;DR: It is demonstrated that the treatment of RPE can differentiate rat mesenchymal cells into IPCs which can be a potential source for the therapy of diabetes.
