Physicists develop ultrathin superconducting film
Experimental physicists in the research group led by Professor Uwe Hartmann at Saarland University have developed a thin nanomaterial with superconducting properties. Below about -200 °C these materials conduct electricity without loss, levitate magnets and can screen magnetic fields.

Guides To Vacuum Technology: Leak free? It depends
Vacuum Technology & Coating
One of my favorite vacuum quotes is from Norman Milleron: “One man’s vacuum is another man’s sewer.” The vacuum systems we use range from ones using relatively crude vacuum (e.g. for the de-airing transformer oil) to more refined (e.g. LPCVD) to much better (PVD) and then the ultimate (e.g. UHV analytical tools). Simply put, the degree of needed vacuum quality is dependent upon the application. Best practice in one application might be a sin in another.

How much gold is in the James Webb Space Telescope?
The James Webb Space Telescope needs to reflect and focus as close to 100% of the light gathered into the instruments, where it can become useful data. And, it needs to be sensitive to light of the right wavelengths to see the most distant objects ever. That's what makes gold such a perfect material to coat it in.

Scientists further understanding of a process that causes heat loss in fusion devices
Scientists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have been studying SEE for decades, and in the past year have made important advances that further their understanding.

A self-healing, water-repellant coating that's ultra durable
A self-healing, water-repellent, spray-on coating developed at the University of Michigan is hundreds of times more durable than its counterparts. It could enable waterproofing of vehicles, clothing, rooftops and countless other surfaces for which current waterproofing treatments are too fragile.


Gold And Aluminum Evaporation Tips
Be sure to read ahead for tips on gold and aluminum evaporation. Gold can be successfully evaporated by a variety of methods. Boats, Baskets, crucibles, and filaments are the most common types of sources used. However, gold, when molten, has 2 issues. Aluminum is a very popular material for evaporation. We have many different sources that can be used to successfully evaporate aluminum. However, there are a few common problems that occur when evaporating this material.
