Journal ArticleDOI
Water desalination using nanoporous single-layer graphene
Sumedh P. Surwade,Sergei N. Smirnov,Ivan Vlassiouk,Raymond R. Unocic,Gabriel M. Veith,Sheng Dai,Shannon M. Mahurin +6 more
TL;DR: It is shown that single-layer porous graphene can be used as a desalination membrane using an oxygen plasma etching process and exhibits a salt rejection rate of nearly 100% and rapid water transport.
Journal ArticleDOI
All‐Organic Vapor Sensor Using Inkjet‐Printed Reduced Graphene Oxide
Vineet Dua,Sumedh P. Surwade,Srikanth Ammu,Srikanth Rao Agnihotra,Sujit Jain,Kyle E. Roberts,Sungjin Park,Rodney S. Ruoff,Sanjeev K. Manohar +8 more
TL;DR: Flexible and lightweight chemiresistormade of a thin film composed of overlapped and reduced graphene oxide platelets (RGO film) that can reversibly and selectively detect chemicallyaggressive vapors such asNO.
Journal ArticleDOI
Effect of airborne contaminants on the wettability of supported graphene and graphite
Zhiting Li,Yongjin Wang,Andrew Kozbial,Ganesh Shenoy,Feng Zhou,Rebecca McGinley,Patrick Ireland,Brittni Morganstein,Alyssa Kunkel,Sumedh P. Surwade,Lei Li,Haitao Liu +11 more
TL;DR: It is demonstrated that airborne hydrocarbons adsorb on graphitic surfaces, and that a concurrent decrease in the water contact angle occurs when these contaminants are partially removed by both thermal annealing and controlled ultraviolet-O3 treatment.
Journal ArticleDOI
Graphene Nucleation Density on Copper: Fundamental Role of Background Pressure
Ivan Vlassiouk,Sergei N. Smirnov,Murari Regmi,Sumedh P. Surwade,Nishtha Srivastava,Randall M. Feenstra,Gyula Eres,Chad M. Parish,Nick Lavrik,Panos G. Datskos,Sheng Dai,Pasquale F. Fulvio +11 more
TL;DR: In this paper, the effect of background pressure and synthesis temperature on the graphene crystal sizes in chemical vapor deposition (CVD) on copper catalyst was quantitatively demonstrated and provided the activation energy for graphene nucleation in atmospheric pressure CVD (9 eV).
Journal ArticleDOI
Flexible, All-Organic Chemiresistor for Detecting Chemically Aggressive Vapors
Srikanth Ammu,Vineet Dua,Srikanth Rao Agnihotra,Sumedh P. Surwade,Akshay M. Phulgirkar,Sanjaykumar Patel,Sanjeev K. Manohar +6 more
TL;DR: Inkjet-printed films of CNTs on 100% acid-free paper are significantly more robust than dip-coated films on plastic substrates, and performance attributes include low sensor-to-sensor variation, spontaneous signal recovery, negligible baseline drift, and the ability to bend the sensors to a crease without loss of sensor performance.
