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, …
Fiber characterization and orientation analysis Fibrous structures occur frequently in both natural and synthetic materials. With micro-CT, it is possible to analyze individual fiber properties (such as diameter), and orientation distribution. With several software tools, in-depth geometric characterization of fibers is possible. “The interface between fiber and matrix material in composites and …
Fiber-reinforced plastics (or polymers) are composite materials made of a polymer matrix that is reinforced with fibers. Typically, most of these composites have strong, stiff fibers in a matrix, which produces a component that often has a low density yet is strong and stiff. Fibers, such as glass (as in fiberglass), carbon, …
Closure systems for glass vials containing parenteral pharmaceuticals are critical for protecting the contents against microbial or other environmental contamination. The most common closure system consists of an elastomer stopper held in place by a crimped aluminum band. Compression is applied during the sealing process, which can affect the closure integrity. We …
One of the most intriguing and historic forensic examinations of a human skull was that of King Richard III’s, the last king of the House of York and the last of the Plantagenet dynasty. King Richard III’s death in the final battle of the Wars of the Roses marked the end of …
Examining the internal structure of archaeological artifacts can provide unique insights that can help us understand the people who made them, their culture, and the technology they developed to shape the world around them. Archaeometry, or the application of scientific techniques to the analysis of archaeological artifacts, is transforming modern archaeology and …
Corrosion in metals can affect a wide array of man-made materials, from reinforced steel in concrete to historic monuments and implanted medical devices. Corrosion causes a loss of strength that can lead to safety hazards in bridges, buildings, and pipelines, as well as in medical devices. The annual direct cost of metallic …
Precious artifacts and historical art objects are often affected by decay, environmental pollution, vandalism, or just simple age and neglect. Micro-CT is well suited to analyze historical artifacts for restoration and preservation, allowing conservators to inspect the exterior surfaces and interior structures without destroying the original objects. Unlike ordinary 2D radiography, …
New High-Capacity 3D X-ray Microscopy Generates Excellent Image Quality in Just Seconds Now it is possible to scan larger, dense objects with a desktop micro-CT instrument, obtaining excellent image quality in as little as 12 seconds. Bruker’s new SkyScan 1273 handles objects up to 500 mm length, 300 mm diameter, and a …
