Construct graphene into porous three-dimensional structures

Kyoto, Japan -- Researchers in Japan have developed a novel yet simple technique, called "diffusion driven layer-by-layer assembly," to construct graphene into porous three-dimensional (3D) structures for applications in devices such as batteries and supercapacitors. Their study was recently published in the journal Nature Communications. 

The resulting products display a foam-like porous structure, ideal for maximizing the benefits of graphene, with the porosity tunable from ultra-light to highly dense through simple changes in experimental conditions. Furthermore, the process is easily scalable for creating large-area films which will be highly useful as electrodes and membranes for energy generation or storage. 

"While we have only demonstrated the construction of graphene-based structures in this study, we strongly believe that the new technique will be able to serve as a general method for the assembly of a much wider range of nanomaterials," concluded Franklin Kim, the principal investigator of the study.

Graphene enable Italy's Vittoria to launch the world's fastest bicycle wheels

International wheel producer Vittoria released a new range of bicycle race wheels that are built from graphene-enhanced composite materials. The new wheels (called Qurano) are the best wheels offered by Vittoria, and they say these are the fastest wheels in the world - all thanks to graphene.

The company explains that adding graphene to their carbon-fiber matrix built wheel rim improved the material properties by 10-30%. The graphene reduces temperature build-up, it increases spoke-hole strength and improves the lateral stiffness. Vittoria tells us that even though the Qurano wheels outperform their previous carbon-fiber wheels, they are priced the same.

Ultra-thin diamond nanothreads

UNIVERSITY PARK, Pa. -- For the first time, scientists have discovered how to produce ultra-thin "diamond nanothreads" that promise extraordinary properties, including strength and stiffness greater than that of today's strongest nanotubes and polymers. A paper describing this discovery by a research team led by John V. Badding, a professor of chemistry at Penn State, was published in the Sept. 21 issue of the journal Nature Materials.

Carbon-Based Nano-Materials and Devices

An ECI Conference
November 3-8, 2013
Promised Land Resort & Lagoon, Hualien, TaiwanTaiwan_Promised-Land-Resort-Lagoon-Hotel_Hualien
This conference aims to provide a forum for researchers, scientists and engineers from different countries worldwide, who are actively involved in the research on nanoscience and nanotechnology, in particular on carbon-based nanomaterials and their device applications such as biological and chemical sensing, energy conversion and harvesting, electronic and photonic applications, catalysis, electrochemistry, and simulations, to disseminate their latest research results and development achievements. In addition to the exciting scientific and technological themes, the conference offers a platform to promote and encourage interaction among researchers for cross-fertilization of ideas and collaboration. The program will consist of a series of invited, contributed oral, and poster presentations. To enhance the interaction with poster presenters, they will also give a short introduction (3 min) to advertise their work. In addition, a panel discussion will be held to promote the interaction among scientists and researchers, including discussions on new research directions for carbon-based nano-materials and devices, summary of the current state of the art and future barriers, and projections of future frontiers.

Future looks bright for carbon nanotube solar cells

Light from the sun creates charges in an ultrathinfilm of carbon nanotubes (blue), which are extracted by fullerene C60 (brown) in this schematic of the groundbreaking proof-of-concept solar cell with greater than 1 percent efficiency.
In an approach that could challenge silicon as the predominant photovoltaic cell material, University of Wisconsin-Madison materials engineers have developed an inexpensive solar cell that exploits carbon nanotubes to absorb and convert energy from the sun.
