Figure 1: Clipped 3D Volumetric rendering of concrete sample While the words concrete and cement are often used interchangeably in everyday conversation, concrete is actually a mixture of aggregate material (rocks, other filler) and cement. X-ray microscopy permits non-destructive examination of geological samples and construction materials, such as cement and concrete, for …
With the global COVID-19 pandemic and the recent focus on preventing and limiting the spread of respiratory diseases, we chose to focus this month on the examination of multilayered air filtration media. The filter studied in this work is intended as a home HEPA filter capable of reducing contaminants in small rooms. …
(Above:) A neuropteran insect (genus Sisyra) showing musculature and general soft tissue morphology. Fixed in Bouin’s fluid and stained with I2E, scanned in ethanol. Virtual horizontal sections one voxel thick (top), and cutaway volume renderings (bottom). Muscles are especially clearly defined, and the complete penetration of iodine makes it more suitable than …
Micro-CT imaging allows researchers to visualize both the internal and external features of an object without destroying the specimen, which makes this technique ideal for digitizing chemically-dried insect specimens. With micro-CT, valuable natural history collections can now be digitized while preserving the original objects. Micro-CT allows for high resolution examination of insect …
Micro-CT has been found to be an effective tool for studying and contributing to improvements of consumer hygiene products such as tampons. Tampons are typically made up of fibrous materials, including rayon and other natural and/or polymeric fibers, and are a key product in the world of women’s health and hygiene. The …
Polypores are a group of fleshy fungi with pores or tubes underneath. Taxonomically, the polypores are complicated and not completely understood, with an amazing amount of morphological diversity. While many can be identified by their macro features and the host tree they are attached to, if a mushroom grows on a large …
As Economic Impact Payments released by Congress in response to the current global pandemic begin rolling out across the country, we focused our imaging on paper currency and the many layers of security built into our paper notes. From special inks, textures, materials, and embedded components, the Treasury Department incorporates many security …
The food processing and manufacturing industry utilizes micro-CT analysis in several ways, from studying the distribution of ingredients within products to inspecting finished packaging for foreign materials and checking product distribution within the packaging. Further, micro-CT allows researchers to study intact internal microstructure data non-invasively, as we were able to demonstrate with …
Micro-CT examination of the primate cranial morphospace allows scientists to explore developmental, evolutionary, and functional influences that have contributed to primate cranial diversity. The primate cranium is quite complex, supporting vital functions such as respiration, olfaction, food acquisition and mastication, communication, and protection of the brain and eyes. Natural selection within different …
Micro-CT has become widely used to analyze and test additively manufactured parts, particularly for porosity analysis and dimensional measurement. In conventional manufacturing, a weld would always be inspected for voids and inclusions, but in additive manufacturing the entire sample is essentially one large weld. Therefore, to qualify and verify safety-critical aerospace, automotive, …
