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 …
Surface renderings of a micro-CT image of a filter sheet sample showing the fibres in red and the outline of the calculated sheet in transparent blue (box size = 4.0mmx2.5mmx0.4mm).

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 …
Imaging food freezing using X‐ray microtomography ABSTRACT This study evaluates the effectiveness of micro-CT for visualizing ice crystal structures formed during freezing of a number of foods. The study looked at various frozen materials, including meat, fish, chicken, potato, cheese, and carrot. The food materials were freeze-dried to remove the ice crystal …
