Nanomagnetic Materials: A review

Gupta T.K.S.P., Verma S.S., Sant Longowal Institute of Engineering and Technology, IN

Nanotechnology and nanostructured materials have the potential to significantly impact energy efficiency, storage, and production. Such applications can be used to monitor and remediate environmental problems, curb emissions from a wide range of sources, and [...]

Sidewall Functionalization of Single-Walled Carbon Nanotubes through C-N Bond Forming Substitution Reactions of Fluoronanotubes

Stevens J., Kini V.U., Huang A., Chiang I.W., Derrien G.A., Khabashesku V.N., Margrave J.L., Rice University, US

Because of the high reactivity of C-F bonds on the sidewalls of single-wall carbon nanotubes, fluorinated SWNTs (fluoronanotubes) can be used as precursors for further derivatization. One such reaction is to replace the fluorine with [...]

DNA Machines for Molecular Self-Assembly

Simmel F.C., Yurke B., Bell Laboratories, Lucent Technologies, US

The molecular recognition properties of DNA are used to construct and power two prototype nanomachines, a pair of molecular tweezers and a nanoactuator. The motion of these machines is driven by hybridization with DNA "fuel" [...]

Three-Dimensional Continuum Simulation of Biological Ion Channels

van der Straaten T.A., Tang J., Eisenberg R.S., Ravaioli U., Aluru N., Rush Medical College, US

We present a self-consistent continuum 3-D simulation of ion permeation through the ompF porin channel, a protein found in the membrane of the e-coli bacterium. The model is based on the simultaneous solution of Poisson's [...]
