Journal ArticleDOI
Multifunctional composites using reinforced laminae with carbon-nanotube forests
Vinod P. Veedu,Anyuan Cao,Xuesong Li,Kougen Ma,Caterina Soldano,Swastik Kar,Pulickel M. Ajayan,Mehrdad N. Ghasemi-Nejhad +7 more
TL;DR: In this article, a 3D composite with carbon-nanotube forests is proposed to improve the in-plane fracture toughness, hardness, delamination resistance, inplane mechanical properties, damping, thermo-elastic behavior, and thermal and electrical conductivities.
Journal ArticleDOI
Tunable Graphene–Silicon Heterojunctions for Ultrasensitive Photodetection
TL;DR: Graphene/Si heterojunctions are found to be excellent weak-signal detectors with photovoltage responsivity exceeding 10(7) V/W and with noise-equivalent-power reaching ∼1 pW/Hz(1/2), potentially capable of distinguishing materials with transmittance.
Journal ArticleDOI
Inkjet Printing of Electrically Conductive Patterns of Carbon Nanotubes
Krisztian Kordas,Tero Mustonen,Geza Toth,Heli Jantunen,Marja Lajunen,Caterina Soldano,Saikat Talapatra,Swastik Kar,Robert Vajtai,Pulickel M. Ajayan +9 more
TL;DR: These results suggest new alternatives for fabricating CNT patterns by simply dispensing/printing the dissolved/dispersed particles on substrates and a cost-effective and scaleable deposition method for generating conductive multi-walled carbon nanotube patterns on paper and polymer surfaces is presented.
Journal ArticleDOI
Stable Aqueous Dispersions of Noncovalently Functionalized Graphene from Graphite and their Multifunctional High-Performance Applications
Xiaohong An,Trevor J. Simmons,Rakesh Shah,Christopher Wolfe,Kim M. Lewis,Morris Washington,Saroj K. Nayak,Saikat Talapatra,Swastik Kar +8 more
TL;DR: A scalable and facile technique for noncovalent functionalization of graphene with 1-pyrenecarboxylic acid that exfoliates single-, few-, and multilayered graphene flakes into stable aqueous dispersions is presented.
Journal ArticleDOI
Direct growth of aligned carbon nanotubes on bulk metals
Saikat Talapatra,Swastik Kar,Sunil K. Pal,Robert Vajtai,Lijie Ci,P. Victor,Manikoth M. Shaijumon,Sumanjeet Kaur,Omkaram Nalamasu,Pulickel M. Ajayan +9 more
TL;DR: The growth of aligned multiwalled CNTs on a metallic alloy, Inconel 600 (Inconel), using vapour-phase catalyst delivery overcomes the substrate limitation for nanotube growth which should assist the development of future CNT-related technologies.
