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.

SPIROL Press-N-Lok™ Pin for plastic housings

The Press-N-Lok™ Pin was designed to permanently retain two plastic components to each other. As the pin is inserted, the plastic backfills into the area around the two opposing barbs, resulting in maximum retention. Assembly time is quicker, and it requires lower assembly equipment costs compared to screws and adhesives -- just Press-N-Lok™!

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. It replaces the traditional printed circuit board and opens up many new opportunities. It takes injection-molded parts and uses laser-direct structuring to etch areas of conductor structures, which are filled with a copper plating process to create very precise electronic circuits. HARTING, the technology's developer, says it's "Like a PCB, but 3D." Tons of possibilities.

New super-tough-to-mimic chemical fingerprint aims to combat counterfeit goods, can be verified on smartphone

Many of us have come home with a new designer bag, watch, or other merchandise only to suspect or discover that it was a fake. More ominously, people die from counterfeit drugs on a daily basis. Globally, consumer counterfeit imports are worth just short of a half-a-trillion dollars annually. The trade is growing, has spread to most industries, and counterfeiters always seem to be at least one step ahead of manufacturers. As such, it is tough for consumers to feel entirely secure about their purchases.

In response, two researchers from the University of Copenhagen's Nano-Science Center have developed what they are deeming a 100 percent pirate-safe labelling system, where individual items receive a label, a so-called "tag," that corresponds with a unique fingerprint. After nearly 10,000 tests, the researchers have proved that their method works.

"You can put it on a wine bottle, a gold watch, a painting -- whatever. The label needn't be larger than a comma. And, it is impossible to copy because the probability that two items share the same fingerprint is nil," says UCPH researcher and associate professor Thomas Just Sørensen, who along with fellow researcher Riikka Arppe-Tabbara has developed the anti-counterfeiting system that they are able to confidently refer to as "the world's safest."

Transparent ink as a fingerprint
The fingerprint, or "tag," consists of a bit of transparent ink containing various microparticles, sprayed upon a bar code on paper, for example. Just as a handful of sand thrown over a surface would, the particles form a random, completely unique pattern of tiny white dots when applied. As there is no chance of creating identical patterns using this method, it is impossible to copy.

Because the ink can be sprayed over any type of bar code and onto many types of materials, the tags are inexpensive to mass-produce. The system works in such a way that each product leaving a factory receives its own fingerprint, which is then registered in a database.

Consumers can check using their phones
Counterfeit safety isn't the only smart thing about this system. Purchasers can validate their product using an ordinary smartphone that, by way of an app, scans an item's fingerprint and checks for a matching database image.

"When purchasing pharmaceuticals online, you have no way of knowing whether what you bought might have been produced in a Ghanaian sweatshop. Today, consumers are not able to check for themselves whether an item is genuine or not. They must trust every step of the production and supply chain. Our system provides every step in this process with equal access to the system," says Sørensen.

During their nearly 10,000 tests, which included various types of mobile phones handled by a variety of users, the researchers encountered zero false positives. The researchers also tested the system together with companies that produce packaging and labels for everything from pain relievers and bottles of wine, to sneakers and tins of biscuits.

The researchers tested the system, based on PUF technology (physical unclonable function), by producing 9,720 tags consisting of QR codes printed on plain paper and sprayed with transparent ink. Each tag was photographed with a mobile phone to create an image database. The images were then scanned with other mobile phones to see if they matched. The results:

  • There was a false match in 0 percent of cases.
  • There was a positive match in 76 percent of cases.
  • In the remaining cases, the photo was either out of focus or the tag was dirty, thus requiring a new image before a match could be made. The researchers say this error will be remediated by software.

The University of Copenhagen has taken out a patent on the system, which is now only missing the software component. The researchers expect the app to be completed over the course of the year. The result has been published in the journal ACS Applied Materials & Interfaces.
