A simple electric field assisted procedure for depositing materials onto the walls of pores of alumina templates shows promise for producing arrays of high purity nanotubes of a wide range of metals and even semiconductors.
New simulations predict that doping silicon nanowires with heavier silicon isotopes can dramatically lower their thermal conductivity-an important step towards the realization of high efficiency thermoelectric nanowire devices.
Magnetic hyperthermia: Heat generated by magnetic particles in liquid suspensions when exposed to alternating magnetic fields is used to kill cancer cells.
