edfas.org ELECTRONIC DEV ICE FA I LURE ANALYSIS | VOLUME 23 NO . 2 50 ABRASIMET M BENCHTOP MANUAL CUTTER FOR QUICK AND EASY SECTIONING The AbrasiMet M from Buehler provides consistent and repeatable cut quality for medium-sized samples. The ease of use, robust design, and expanded chamber make this machine ideal for quick and easy sectioning in demanding environments. TheAbrasiMetM is abenchtopmanual cuttingmachine that provides consistent sectioning results using 10 in. and 12 in. blades. The sliding door allows easy access to the 635mmwide cutting chamber toquickly position samples for cutting. A powerful 4 kWmotor and ergonomic cutting arm provide a smooth and efficient cutting motion. The AbrasiMet M is a durablemachine that provides userswith a quick, clean, and simple solution for their cutting needs. The design features amotor that is separated from the cutting armwhich reduces the force required to cut. This also allows the user to better feel the resistance andmore accurately gauge the correct force to apply. MXENE-COATED FABRIC COULD CONTAIN ELECTRONIC INTERFERENCE IN WEARABLE DEVICES Researchers at Drexel University’s Col lege of Engineering have reported that fabric coated with a conductive, two-dimensional material called MXene, is highly effective at blocking electromagnetic waves and potentially harmful radiation. The discovery is a key devel- opment for efforts toweave technological capabilities into clothing and accessories. Materials that block electromagnetic waves had a commercial moment a handful of years ago when fears that high-tech thieves could scan or copy credit cards, passports, or hack into laptops and contactless car keys had people putting them in special wallets, bags, and protected pockets. While reporting suggests these fears were overblown, the demand for this sort of textile is likely to grow as more manufacturers incorporate sensing and communication technologies into fabrics. They could also be deployed in national defense orga- nizations to shielddevices fromtracing andhacking and to protect people fromstrongmicrowave radiation; the kind that might have been used against diplomats according to recent reports. “Wearable devices will need shielding from the elec- tromagnetic interference (EMI) regularly produced by mobile devices, and that shielding should be integrated as part of the garment,” says Yury Gogotsi, Distinguished University and Bach professor at Drexel, who led research recently published in thematerials science journal Carbon . “We have known for some time that MXene has the ability to block electromagnetic interference better than other materials, but this discovery shows that it can effec- tively adhere to fabrics and maintain its unique shielding capabilities.” “MXenes are well-suited for use as shielding because they can be stably produced as a spray coating, an ink, or a paint, so they can be applied to textiles without adding much weight or taking up more room,” Gogotsi says. “We have alsodiscovered that MXene shielding can absorb and reflect electromagnetic waves, so it not only protects the wearable devices and electronic gadgets, but alsoprotects people from strong electromagnetic fields.” The researchers’ most recent finding shows that dip- coating regular cotton or linen fabric in anMXene solution will turn it into an equally formidable shieldingmaterial— blocking EMI at greater than 99.9% effectiveness.

Save time preparing the cut and reduce the risk of injury when changing blades. Quickly adjust the cutting handle height, angle, and length to optimize themachine for any user. Better ergonomics allowusers to perform the sectioning process with ease and the simple design makes it quick to adjust for different users. The high-capacity tank (30 gal, 110 L) features a nested tank designwhich filters debris fromcoolant. By regularly cleaning out the inner tank, which traps large debris, users can extend the lifetime of their coolant. This allows users to spend less time cleaning the full systemand spendmore time cutting samples or on other processes. For more information, visit www.buehler.com.
