- Spatially Controlled Graphitization of Reduced Graphene Oxide Films via a Green Mechanical Approach
Jin-Yong Hong, Jing Kong and Sung Hyun Kim
Article first published online: 28 JUL 2014 | DOI: 10.1002/smll.201401185
An effective approach to fabricate micropatterned reduced graphene oxide sheets is explored on the basis of the pressure-assisted thermal graphitization as a concept of eco-friendly method. The high pressure can considerably reduce the graphitization temperature and substantially accelerate the kinetics of phase transformation of non-crystalline graphene domain, leading to enhance the degree of graphitization.

A simple and robust method termed “fiber-assisted molding (FAM)” is presented to create biomimetic three-dimensional surfaces with controllable curvature and helical twist. The alignment of muscle fibrils and the assembly of helically patterned extracellular matrix by cells demonstrate the potential of this method for tissue engineering and other materials science applications.
- Gold Nanorods with Sub-Nanometer Separation using Cucurbit[n]uril for SERS Applications
Samuel T. Jones, Richard W. Taylor, Rubén Esteban, Enass K. Abo-Hamed, Paul H. H. Bomans, Nico A. J. M. Sommerdijk, Javier Aizpurua, Jeremy J. Baumberg and Oren A. Scherman
Article first published online: 28 JUL 2014 | DOI: 10.1002/smll.201401063
The capability of cucurbit[n]uril to align gold nanorods, leading to optical coupling into the infrared region, is shown. Cryo-TEM and tomographic imaging confirm the presence of aligned Au nanorods. Full electromagnetic simulations, which support the observed plasmonic modes and predict large enhancements in the inter-particle junction, are performed. This construct is then further utilized for surface enhanced Raman spectroscopy.
- Multifunctional Superamphiphobic TiO2 Nanostructure Surfaces with Facile Wettability and Adhesion Engineering
Jian-Ying Huang, Yue-Kun Lai, Fei Pan, Lei Yang, Hui Wang, Ke-Qin Zhang, Harald Fuchs and Li-Feng Chi
Article first published online: 28 JUL 2014 | DOI: 10.1002/smll.201401024
Liquid adhesion on superamphiphobic surface can be simply and in-situ achieved with a novel “combination method”. These functional patterning surfaces would be versatile platforms for microfluidic devices, biomedical scaffolds, or molecular sensing. In a proof-of-concept study, microdroplet manipulation, gas sensing, ZnO patterning, and site-selective cell immobilization are demonstrated.
- Inkjet Printed Bilayer Light-Emitting Electrochemical Cells for Display and Lighting Applications
E. Mattias Lindh, Andreas Sandström and Ludvig Edman
Article first published online: 28 JUL 2014 | DOI: 10.1002/smll.201400840
A novel inkjet-printed light-emitting electrochemical cell (LEC), which allows for well-defined and patterned light emission through an easily adjustable, mask-free, and additive fabrication process, is reported. Inkjet-printed bilayer LEC devices that feature uniform yellow-green light emission to the naked eye, and static displays that deliver well-defined and high-contrast messages with a pixel density of 170 PPI, are presented.
