By noreply@blogger.com (bw) Superlattices are nanometer-scale structures made up of two materials layered on top of each other, like the alternating bread and meat in a club sandwich. A nanometer - visible only with the aid of a high-power electron microscope - is one billionth of a meter, and some nanomaterials are...

By Yong Zhu Welcome to the January 2010 issue! In the issue of May 2007 , Prof. Xiaodong Li outlined the existing experimental methods for mechanical characterization of 1D nanostructures. In this issue, I will follow along the same line but focus on experimental methods enabled by microelectromec...

PhysOrg.com) -- Scientists at the U.S. Department of Energy`s Brookhaven National Laboratory have found a new way to use a synthetic form of DNA to control the assembly of nanoparticles - this time resulting in switchable, three-dimensional and small-cluster structures that might be us...

In their previous studies, the scientists used single strands of DNA attached to individual nanoparticles as linker molecules. When the free ends of these ... and more »

Graphene -- a single-atom-thick sheet of carbon, like those seen in pencil marks -- offers great potential for new types of nanoscale devices, if a good way can be found to mold the material into desi...

Methods for selectively depositing nanostructures on a support layer include contacting the support layer with functionalized catalyst particles. The functionalized catalyst particles can form a self-assembled monolayer of catalyst particles on the support layer and the functi...

The invention is directed to carbon nanostructure composite systems which may be useful for various applications, including as dry adhesives, self-cleaning applications, electronics and display technologies, or in a wide variety of other areas where organized nanostructures ma...

Provided are novel nanostructures comprising hollow nanospheres and nanotubes for use as chemical sensors and molecular specific photothermal coupling agents. The nanostructures can be used in laser-induced phototherapy for treatment of cancer and other disorders. The nanostruc...

By K Dayal We describe a method of constructing exact solutions of the equations of molecular dynamics in settings out of equilibrium. These solutions correspond to some viscometric flows, and to certain analogs of viscometric flows for fibers and membranes that have one or more dimensions of atomi...

By Jianyu Huang “fractional nanotubes.” We demonstrate that these curved carbon nanostructures possess a number of interesting dipoles of 0.87 and 1.14 debye/Å for zigzag and armchair inclinations, respectively. An unusual, weak AA This entails a type of quantum Hall behavior markedly different from...

A process for growth of boron-based nanostructures, such as nanotubes and nanowires, with a controlled diameter and with controlled chemical (such as composition, doping) as well as physical (such as electrical and superconducting) properties is described. The boron nanostructur...

By Michael The Brookhaven team has previously used DNA, the molecule that carries life’s genetic code, to link up nanoparticles in various arrangements, including 3-D nano-crystals. The idea is that nanoparticles coated with complementary strands of DNA — segments of genetic code sequence tha...
