Journal ArticleDOI
Reduced graphene oxide-based hydrogels for the efficient capture of dye pollutants from aqueous solutions
Jitendra N. Tiwari,Kandula Mahesh,Nhien H. Le,K. Christian Kemp,Rupak Timilsina,Rajanish N. Tiwari,Kwang S. Kim +6 more
TL;DR: In this paper, a 3D reduced graphene oxide (RGO)-based hydrogels were synthesized by the reduction of graphene oxide using sodium ascorbate and showed a large surface area, and a uniform pore size distribution.
Journal ArticleDOI
Engineered Carbon-Nanomaterial-Based Electrochemical Sensors for Biomolecules
TL;DR: This review article gives a brief overview of voltammetric techniques and how these techniques are applied in biosensing, as well as the details surrounding important biosensing concepts of sensitivity and limits of detection.
Journal ArticleDOI
Enhanced Cr(VI) removal using iron nanoparticle decorated graphene
TL;DR: Nanoscale iron particles decorated graphene sheets synthesized via sodium borohydride reduction of graphene oxide, showed enhanced magnetic property, surface area and Cr(vi) adsorption capacity compared to bare iron nanoparticles.
Journal ArticleDOI
Near-field focusing and magnification through self-assembled nanoscale spherical lenses
Ju Young Lee,Byung Hee Hong,Byung Hee Hong,Woo Youn Kim,Seung Kyu Min,Yukyung Kim,Mikhail V. Jouravlev,Ranojoy Bose,Keun Soo Kim,In-Chul Hwang,Laura J. Kaufman,Chee Wei Wong,Philip Kim,Kwang S. Kim +13 more
TL;DR: Lee et al. as mentioned in this paper used nanoscale spherical lenses that self-assemble by bottom-up integration of cup-shaped organic molecules called calixarenes to obtain near-field features of the order of 200 nm.
Journal ArticleDOI
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.
