Study reveals new structure of gold at extremes

Three of the images taken in the Argonne National Laboratory's Dynamic Compression Sector highlight diffraction signals recorded on the X-ray detector. Section 1 shows the cubic face-centered initial structure; Section 2 shows the new cubic body-centered structure at 220 GPa; and section 3 shows the liquid gold at 330 GPa. Picture credits: Lawrence Livermore National Laboratory Gold is an extremely …

Air Force Experimental Satellite is referred to as the "largest unmanned structure in space"

The DSX satellite collects data used to study the radiation environment in space. WASHINGTON – An air force satellite spanning nearly the length of a football field was successfully deployed at the Air Force Research Laboratory on July 12 AFRL's Demonstration and Science Experiments (DSX) will gather data to study the radiation environment used in space. DSX was the largest …

Federal law would allow clean energy companies to structure themselves like oil companies

Enlarge / Wind turbines near Palm Springs, California. Last week, US Senators and Representatives introduced Senate and House Bill to a corporate structure originally reserved for oil, gas and coal companies to clean energy companies. This structure, known as the Master Limited Partnership (MLP), allows fossil-fueled companies to use lower taxes on limited partnerships while allowing them to issue publicly …

Scientists discover an ancient rock structure that hides under the Antarctic and moves the ice

Deep beneath the frozen wastelands of Antarctica, scientists have discovered ancient tectonic plate structures that have a major impact on the melting patterns in the continental largest ice shelf. The Hidden Rock, which has been around for hundreds of millions of years, controls the flow of water around the gigantic Ross Ice Shelf. This shelf is currently acting as a …

Notre-Dame Cathedral: This art historian used lasers to digitally map the structure. Now he could help save it

Andrew Tallon, art professor at Vassar College, used lasers to painstakingly scan the Cathedral in 2015, giving us an almost perfect digital replica of the gothic structure. His work could help architects and engineers rebuild after the fire on Monday. Tallon studied Gothic architecture and tried to understand how medieval construction workers built some of Europe's great cathedrals. So he …

Researchers create first carbon fibers with uniformly porous structure

Conventional (A, B) and new (C) methods for synthesizing carbon fibers from various polymer precursors. (A) Pure PAN is electrospun into a fiber, oxidized at 280 ° C in air to crosslink PAN (blue), and then pyrolyzed at 800 ° C in N2 to generate carbon fibers (gray). An individual polymer fiber (purple) is magnified for illustration. (B) PAN is …

For once, the 49er leadership structure is holding together – now they need some winnings in 2019 – The Athletic

Kyle Shanahan is not afraid of training, although many others in his current position would probably be quite nervous at the moment. John Lynch is not afraid of anything. Jed York is not afraid. Give them all the credit. Comprehensive security and comprehensive support is not always easy to achieve, after an NFL regime has gone in two seasons 10-22 …

From the cup to the dissolved 3D structure in minutes – ScienceDaily

A joint study by UCLA / Caltech has shown that it is possible to preserve the structure of small molecules such as certain hormones and drugs in just 30 minutes. That's hours and even days less than before. The team used a technique called MicroED (MicroED), which was previously used to learn the 3D structures of larger molecules, especially proteins. …
