One-part epoxy changes from red to clear under UV

Master Bond UV15RCL is a low-viscosity, cationic-type UV-curing system with a special color-changing feature. The red material changes to clear once exposed to UV light, indicating that there is UV light access across the adhesive material. Although this change in color from red to clear does not indicate a full cure, it does confirm that the UV light has reached the polymer. This epoxy is an excellent electrical insulator. UV15RCL adheres well to metals, glass, ceramics, and many plastics, including acrylics and polycarbonates.

Load fasteners with integrated RFID

A crane, rope, or chain may be required when something needs lifting -- plus anchoring points on the load. JW Winco offers a wide range of solutions to fasten the load securely, including: lifting eye bolts and rings (with or without rotation), eye rings with ball bearings, threaded lifting pins, shackles, lifting points for welding, and more. Some, such as the GN 581 Safety Swivel Lifting Eye Bolts, even have integrated RFID tags to clearly identify specific lifting points during wear and safety inspections and manage them digitally and without system interruption.

Couplings solve misalignments more precisely with targeted center designs

ALS Couplings from Miki Pulley feature a simplistic, three-piece construction and are available in three different types for more precisely handling parallel, angular, or axial misalignment applications. The key feature of this coupling design is its center element. Each of the three models has a center member that has a unique and durable material and shape. Also called a "spider," the center is designed to address and resolve the type of misalignment targeted. Ideal for unidirectional continuous movement or rapid bidirectional motion.

What is 3D-MID? Molded parts with integrated electronics from HARTING

3D-MID (three-dimensional mechatronic integrated devices) technology combines electronic and mechanical functionalities into a single, 3D component.

Researchers create the densest object on Earth by compressing copper

If copper was found in the core of Saturn it would have the same crystalline structure as the copper pipes found in many homes, according to new research from Lawrence Livermore National Laboratory (LLNL) and Johns Hopkins University.

In a paper published Jan. 9, 2020, by Physical Review Letters, the research team reveals that copper maintains its crystalline structure at pressures ranging from one atmosphere (room pressure) to more than 30 million atmospheres.

Using LLNL's National Ignition Facility, the team compressed microscopic copper samples -- thinner than a human hair -- to pressures of 30 million atmospheres in less than a billionth of a second. These extreme conditions tripled the sample's density, creating the densest object on the planet for a brief moment in time.

In the center of the National Ignition Facility's Target Chamber, researchers created the densest object on the planet for a brief moment in time by compressing microscopic copper samples to pressures of 30 million atmospheres in less than a billionth of a second.

 

 

 

 

"Achieving this microscopic size and these short-lived conditions was a feat unimaginable before the advent of modern engineering," said Dayne Fratanduono, LLNL physicist and lead author of the paper. "Today, experimental physicists can generate and probe the complex behavior of materials at pressures surpassing the conditions found deep within the cores of Saturn and Jupiter. Generating such extreme states of matter requires confining large amounts of energy into extremely tiny volumes, which we accomplished using NIF, the largest and most energetic laser facility in the world."

Preparing the samples and obtaining measurements for this study required leading-edge equipment and diagnostics. The researchers used diamond turning machines to generate microscopic copper "stair steps," whose surface roughness surpassed optical qualities, and precision metrology to measure sample thickness to 1 billionth of a meter. During the experiment, they tracked the copper sample traveling at 50,000 miles per hour using a velocity interferometer -- the world's most sophisticated radar gun.

"Producing high-energy-density states of matter is easy to achieve in practice, but extremely difficult to accurately measure, and NIF is one of the few facilities in the world currently capable of performing such measurements," Fratanduono said. "These unique, precision capabilities enable us to benchmark the compressibility of copper to extreme conditions, so that other scientists in high-energy-density physics may utilize copper as a high-precision standard, much like the National Institute of Standards and Technology provides well-calibrated standards to industry, academia, and government."

To determine how copper stiffness responded to increasing pressure, the research team took a series of X-ray images to monitor the crystalline structure as the copper compressed. They also measured how the speed of sound waves changed as the copper was squeezed. From these measurements, the team benchmarked the behavior of copper at extreme conditions and developed a microscopic interpretation of its quantum behavior.

"Our experiments have shown that we are able to accurately predict the behavior of copper to extreme conditions, and we suspect that this behavior may be common amongst the other noble metals -- metals that possess nearly spherical electron orbitals with one conduction electron per atom," Fratanduono said. "Future work will test our understanding of the quantum behavior of materials at extremes and examine the behavior of more exotic materials."

Co-authors on the paper include Ray Smith, Suzanne Ali, Dave Braun, Amalia Fernandez-Panella, Shuai Zhang, Richard Kraus, Federica Coppari, James McNaney, Michelle Marshall, Leo Kirch, Damian Swift, Marius Millot, and Jon Eggert from LLNL and June Wicks from Johns Hopkins University.
