Europe’s Smart Highway Will Shepherd Cars From Rotterdam to Vienna

Seeing taillights flash up ahead, you slam on the brakes, thus sending the signal you’ve just received to the car behind, with a lag. That car relays the same information with a lag of its own, creating a monstrous traffic jam kilometers down the line.

That’s the sorry state of car-to-car communication today. Drivers must be totally alert; yet even so, they can’t help triggering perverse results. This problem will start to end this decade, as cars begin to communicate with one another in a way that allows each to see through the eyes of those that have gone before. The roads will be safer, traffic jams fewer, and cars more autonomous.

New Filter Doubles Nuclear Fuel Extractable from Seawater

It pulls uranium out at record rates—but real-world tests are still to come

The International Atomic Energy Agency expects nuclear power to grow significantly in the coming decades, by up to 82 percent by the year 2050. That would create an increase in demand for uranium that reserves on land may not be able to meet.

But the world’s oceans, according to the U.S. Department of Energy, contain at least 500 times more uranium than in all known terrestrial reserves. That equates to more than 4.5 billion metric tons of the element in seawater, albeit present at an extremely dilute concentration of 3.3 parts per billion, and scientists have been trying to find efficient ways to extract it.

EP29LPSP: Applications in Plasma Physics, Astronomy, and Highway Engineering

Ideal for demanding cryogenic environments, two-part EP29LPSP can withstand temperatures as low as 4K

3 min read

Since its introduction in 1978, Master Bond EP29LPSP has been the epoxy compound of choice in a variety of challenging applications. Ideal for demanding cryogenic environments, two-part EP29LPSP can withstand temperatures as low as 4K and can resist cryogenic shock when, for instance, it is cooled from room temperature to cryogenic temperatures within a 5-10 minute window. Optically clear EP29LPSP has superior physical strength, electrical insulation, and chemical resistance properties. It also meets NASA low outgassing requirements and exhibits a low exotherm during cure. This low viscosity compound is easy to apply and bonds well to metals, glass, ceramics, and many different plastics. Curable at room temperature, EP29LPSP attains its best results when cured at 130-165°F for 6-8 hours.

In over a dozen published research articles, patents, and manufacturers' specifications, scientists and engineers have identified EP29LPSP for use in their applications due to its unparalleled performance in one or more areas. Table 1 highlights several commercial and research applications that use Master Bond EP29LPSP. Table 2 summarizes several patents that reference EP29LPSP. Following each table are brief descriptions of the role Master Bond EP29LPSP plays in each application or invention.
