Jumpy electrons make chromophores semiconductors suitable for nanoscale electronics from PhysOrg.com

The future of high-speed electronics might very well be defined by linking together small, "electrically jumpy" molecules called chromophores. According to researchers at the University of Pennsylvania and St. Joseph's University, electrical charges can zip along chains of linked chromophores faster than any electrical charge yet observed in organic semiconductors, beating the previous benchmark in this regard by a factor of three.

Am I a bad Friend

As I began the Portrait of Friends project, not to be confused with the failed enemies of Batman project, I realized I don't have many if any photos of my friends.
In fact most of the drawing are from myspace photos. So am I a bad friend, the answer is yes!

Nanoparticles and Lasers Create Cancer-Killing Microbubbles from PhysOrg.com

One promising use of gold nanoparticles is to use them to convert laser energy into heat that can kill malignant cells. Now, in a promising twist on this approach to anticancer therapy, an international team of investigators has developed a method that uses clusters of gold nanoparticles to create vapor microbubbles that can kill targeted cells.

Sticky Surfaces Turn Slippery With the Flip of a Molecular Light Switch from PhysOrg.com

Changing a surface from sticky to slippery could now be as easy as flipping a molecular light switch. Researchers at Rensselaer Polytechnic Institute have created an “optically switchable” material that alters its surface characteristics when exposed to ultraviolet (UV) light. The new material, which is described in the June 19 issue of the journal Angewandte Chemie International Edition, could have a wide variety of applications, from a protein filter for biological mixtures to a tiny valve on a “lab-on-a-chip.”

Painting by numbers part deux

Next I do a quick underpainting in one dark and one light color.
I like to use disposable brushes for this and save the more expensive brushes for detailed work.

Painting by numbers

1) O.K. first I strech the canvas then prime the canvas.
2) Now I cover the canvas with light green spray-paint.



3) A sketch of the painting is done in red marker.
