Avoiding Common Mistakes in Extractables/Leachables Program Design

Mistakes in program design for extractables/leachables testing can lead to significant delays, rounds of questions, and the need for additional testing. And, in some cases, all of the extractables/leachables testing may need to be repeated. To avoid these costly mistakes, it is important to understand the current standards as well as the current interpretations and opinions from regulators interpreting these standards. In this whitepaper the experts from WuXi AppTec discuss the current standards, interpretations and will provide you with tips to avoid common mistakes when designing your program.

Visual Microphone Identifies Structural Defects

A new technique from Massachusetts Institute of Technology researchers estimates material properties of physical objects, such as stiffness and weight, from video.The method could have application in the field of nondestructive testing, determining materials’ physical properties without extracting samples from them or subjecting them to damaging physical tests. Structural defects, for example, could be found in an airplane’s wing by analyzing video of its vibration during flight.A given object’s preferred frequencies, and the varying strength of its vibrations at those frequencies, produce a unique pattern, which a variation on the visual-microphone algorithm was able to extract.The MIT researchers then used machine learning to find correlations between those vibrational patterns and measurements of the objects’ material properties. The correlations they found provided estimates of the elasticity of the bars and of the stiffness and weight per unit area of the analyzed fabrics. Moreover, aberrations or discontinuities in an object’s typical vibrational patterns could indicate a defect in its structure.SourceAlso: Read a Q&A with a NASA Lead Non-Destructive Evaluation Engineer.

Will iris detection become a mainstream smartphone feature?

This week's Question: The Fujitsu Arrows NX F-04G, a new smartphone set for release in Japan, comes with a built-in retinal scanner that can be used for a variety of different functions, including unlocking the device, accessing apps, and making mobile payments. A front-facing infrared camera and an infrared LED light illuminate the user's eyes, verifying his or her unique iris pattern. Although the technology is currently only available in Japan, bigger companies like Samsung are also working on iris-detecting smartphones. What do you think? Will iris detection become a mainstream smartphone feature?

Bonded Magnets: A Versatile Class of Permanent Magnets

Permanent magnets are ubiquitous in modern societies. Devices which use permanent magnets include motors, sensors, actuators, acoustic transducers, etc. These are used in home appliances, speakers, office automation equipment, aerospace, wind turbine generators, medical laboratory diagnostic test equipment, and more. It is estimated, for example, that a typical automobile uses up to 120 permanent magnets in windshield wipers, starter motors, seat adjusters, door lock actuators, fuel pumps, sensors, gauges, etc. The development of Hybrid Electric Vehicle and Electric Vehicle drive technologies has been greatly enhanced by the availability of high performance magnetic materials.

Researchers Create Shape-Shifting Plastic

Researchers from Washington State University and the Department of Energy's Oak Ridge Laboratory have created a tunable shape-memory polymer. The shape-shifting plastic can “remember” its original shape and return to it after being deformed with heat or other forces. The materials exhibit triple-shape memory behavior; the polymers can transform from one temporary shape to another temporary shape at one temperature, and then back to a permanent shape at another temperature. Changing the ratio of ingredients allows the researchers to control the overall properties of the material. The team’s method also uses off-the-shelf chemicals that can be easily scaled up to manufacture the material in bulk.Mixing the shape-memory polymers with other materials could produce stronger and stiffer composite parts that can later be recycled or reprocessed. Recyclable carbon fiber and glass fiber composites, for instance, are in high demand in the automotive industry.The material could also be used as binding glue for new types of rare earth-free magnets made from powders. The team is already experimenting with 3-D printing powder-based magnets with shape-memory polymers. Source Read other Materials & Coatings tech briefs.
