WHY IS SEM IMAGING USED TO STUDY STYROFOAM? SEM imaging is an ideal tool to check the size and homogeneity of the cells in the polymer foam structure, and if the material has a closed or open cell structure. Other elements that can be studied are the foaming and cell formation efficiency, and how different agents influence these processes. Chemical...

WHY IS SEM IMAGING USED TO STUDY GLASS FIBRES? SEM imaging is an ideal tool to check the homogeneity, compactness aof glass fibres in a polymer matrix. Other defects such as poor adhesion of the fibres to the polymer matrix (shown as clean fibres) can also easily be detected. Chemical microanalysis techniques (EDS) used in conjunction with scanning electron microscopy...

WHY IS SEM IMAGING USED TO STUDY NANOFIBRES? SEM imaging is an ideal tool to check the homogeneity and diameter of nanofibres. SEM manufacturers have developed specific software applications for a fully automatic fibre diameter distribution measurement. Nanofibres are also used in air filtration applications for antibacterial and nanoparticle applications. SEM imaging (eventually combined with EDS chemical microanalysis techniques) to...

WHY IS SEM IMAGING USED TO STUDY FACE MASKS? SEM imaging is an ideal tool to check the homogeneity, compactness and average diameter of fibres in the different face mask layers. The SEM image show a 10nm gold coated non-woven polypropylene filtration layer at 1400x magnification. Some SEM manufacturers have developed specific software applications for a fully automatic fibre diameter...

WHY IS SEM IMAGING USED TO STUDY NANOFIBRES? SEM imaging is an ideal tool to check the fibre surface properties and the structure of collagen networks. In general, a lot of organic and biological samples such as tissue, blood vessels and cartilage provide very interesting information when imaged by SEM. Such materials however are very poor electrical and thermal conductors...

WHY IS SEM IMAGING USED TO STUDY DIATOMS? Diatoms are used to help determine the origin of materials containing them. One important field of use is forensics. A typical application is to differentiate a death by submersion form a post-mortem immersion of a body in water. Because the composition of diatoms is specific for a specific location, a sample of...

Ford Motor Company is an American multi-national automaker that recently announced a plan to invest US$22 billion through 2025 in the electrification of their mobility products. The ChallengeIn electric vehicles (EVs), new processing methods for gears must convert the high-force torque from electric motors to the RPMs at the wheel. This much be achieved while also reaching the consumer's intended...

As a lab operator, the relentless time pressure and the quest for swift, high-quality output are all too familiar challenges. But what if there were a solution that could revolutionize your workflow and save you valuable time? The Power of SEM TechnologyYou're likely accustomed to working with optical microscopes or SEMs for their superior imaging capabilities. SEM, with its electron...

https://www.youtube.com/embed/ZsC-wJoCY-w SmartSetup is a feature implemented on Zygo’s latest generation of 3D optical profilers to address four important setup tasks:  1. Find the part2. Set the appropriate light level3. Set the appropriate scan range4. Get the first measurement Finding the part (i.e. fringes) can be time-consuming for experienced as well as new users. It is often relatively easy to find fringes at higher magnifications like 10x on a rough surface, but it...

Mark Elo, US National Sales Manager, Tabor Electronics RF and Microwave theory sits on the shoulders of Maxwell, and Hertz with the theoretical development of the connection between electricity and magnetism that started in the early 1800s. Today the use of RF and Microwave radios are ubiquitous, used by everyone every day, but still, the subject remains complex and takes...
