#Plasmons Influence Carbon-Based Nanoparticles for Sensitizing Cancerous Tumors In a study published in EPJ D,

For the first time, Harvard researchers have created similar wakes of light-like waves moving on a metallic surface, called surface plasmons,
"The creation and control of surface plasmon wakes could lead to new types of plasmonic couplers
Surface plasmons are confined to the surface of a metal. In order to create wakes through them, Capasso's team designed a faster-than-light running wave of charge along a one-dimensional metamaterial--like a powerboat speeding across a lake.
The metamaterial, a nanostructure of rotated slits etched into a gold film, changes the phase of the surface plasmons generated at each slit relative to each other
increasing the velocity of the running wave. The nanostructure also acts like the boat's rudder, allowing the wakes to be steered by controlling the speed of the running wave.
The team discovered that the angle of incidence of the light shining onto the metamaterial provides an additional measure of control

the light is turned first into so-called surface-plasmon-polaritons. Plasmon-polaritons are a combination of electromagnetic fields
and electrons that propagate along a surface of a metal strip. At the end of the strip they are converted back to light once again.
The advantage of this detour is that plasmon-polaritons can be confined in a much smaller space than the light they originated from.
but rather plasmon-polaritons that are sent through an interferometer that is only half a micrometer wide.
and hence the velocity of the plasmons in one arm of the interferometer can be varied,
After that, the plasmons are reconverted into light, which is fed into a fibre optic cable for further transmission.
and that thus modulates the plasmons inside the interferometer. As such a modulator is much smaller than conventional devices it consumes very little energy-only a few thousandth of Watts at a data transmission rate of 70 Gigabits per second.

To solve this problem the Japanese researchers created plasma voxels using femtosecond lasers instead. A femtosecond is a quadrillionth of a second

#XEI Scientific and University of Southern California announce a publication in Advanced Materials on the use of downstream plasma cleaning The research team of Associate professor Stephen Cronin is located in the Ming Hseih Department of Electrical engineering
The paper describes how gentle oxygen plasma treatment produces direct bandgap transition in many-layer Mos2.*
*The authors (Rohan Dhall et al) chose to use the XEI Evactron Soft Clean plasma cleaner for the process.
Here, the plasma is generated by flowing room air past an electrode supplied with 20 W of RF power at 200 mtorr.
Samples are placed 6-10 cm away from the plasma source. Ionized oxygen atoms diffuse towards the sample chamber with low kinetic energies.
Samples were exposed to the O2 plasma for about three minutes. While typical plasma cleaners used in semiconductor fabrication operate using a"sputtering"mechanism where the sample is bombarded with ions carrying significant kinetic energy
remote plasma cleaners rely mainly on the chemical reactivity of the ionized oxygen to remove surface contaminants.
Analytical techniques including photoluminescence spectroscopy (PL), Raman spectroscopy, atomic force microscopy (AFM), and electron energy loss spectroscopy (EELS) are used to follow the effects of the plasma treatments on a range of samples having different numbers of layers.
The authors successfully demonstrate the generation of an indirect-to-direct bandgap transition in many-layer Mos2 through the use of an easy to use, scalable oxygen induced plasma process.
