Cooper-Carbon Nanostructured Composite Coatings with Controlled Structure

Electrodeposition of Nanostructured Magnesium Coatings

In this work, we report on the electroplating of ultrafine and uniform magnesium (Mg) films on copper (Cu) and carbon nanotube (CNT) paper substrates. By controlling the process parameters and utilizing the pulsed deposition method, the average grain size of Mg was reduced to nanodimensions. Surface pretreatment of the substrates by depositing a seed layer was found to be an efficient strategy ...

Polymeric nanostructured composite films*

This research news describes the construction of polymeric nanostructured composite film based on a variety of interactions, such as hydrophobic–hydrophilic effect, electrostatic interaction, hydrogen bonding, etc. The work focused on developing strategies to solve the basic problems in the area of ultrathin film research, such as stability, improving the interface quality, creating patterned i...

Nanostructured composite coatings to reduce bacterial infection on titanium orthopedic implants

Enhanced resonator sensitivity with nanostructured porous silica coatings.

We present a strategy to increase the sensitivity of resonators to the presence of specific molecules in the gas phase, measured by the change in resonant frequency as the partial pressure of the molecule changes. We used quartz crystals as the resonators and coated them with three different thin films (<1 microm thick) of porous silica: silica xerogel, silica templated by an ordered hexagonal ...

0 Cooper Instability of Composite Fermions

When confined to two dimensions and exposed to a strong magnetic field, electrons screen the Coulomb interaction in a topological fashion; they capture and even number of quantum vortices and transform into particles called 'com-posite fermions' [1–3]. The fractional quantum Hall effect [4] occurs in such a system when the ratio (or 'filling factor', ν) of the number of electrons and the degene...
