Figure 1: Photograph of 3D printed shark denticles extracted from micro-CT imaging data Biomimicry of Shark Denticles Although it is commonly known that most fish species have scales, it may be less widely known that shark skin goes one step further with the presence of denticles more like teeth than traditional scales. While …
Figure 1: Photograph of beans moving from unroasted, to medium roast, to dark roast Roasting coffee beans causes meaningful changes in their microstructure, such as the increase in total pore volume, porosity, and density due to the rupture of bonds in the internal structure of the coffee beans during roasting. These changes …
Figure 1: Clipped rendering of sandwich cookie with three individual filling layers Utilizing our SkyScan 1275 desktop micro-CT, we were able to quickly image a multilayered sandwich cookie, taking a virtual look within to investigate the distribution of the three filling layers and inclusions while resolving the fine structures and porosity of …
Figure 1: Volumetric rendering of e-cigarette device E-cigarettes are battery-operated devices that heat a special liquid to produce an aerosol that users inhale. They come in a range of shapes, with some looking like USB drives and others looking like pens. Marketed as tools for quitting or cutting down on smoking, the …
Figure 1: Volumetric rendering of yeast dough sample Density in bread and other porous foods is difficult to measure accurately, with true, apparent, and bulk being different types of densities based on how volume is measured. Predicting food density based on composition and processing conditions allows researchers to fill gaps in nutrient …
Micro-CT imaging is used to assess trabecular and cortical bone morphology, allowing researchers to measure bone microarchitecture without relying on stereologic models. Researchers can non-destructively acquire the three-dimensional architecture of bone from any site within a small animal. The sample remains intact, allowing researchers to follow up with genetic and histological analysis. …
Figure 1: Photograph of known (left) and questioned (right) capsules Pharmaceutical counterfeits impact the intellectual property of the originator of the drug but also undermine the safety of the public. Because counterfeit drugs often contain only small amounts of the active ingredient, they can abate some symptoms but not fully cure or …
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 …
