Microstructures Explain Beetle Exoskeleton Strength
Using microtomography and other techniques, researchers identified the exoskeletal toughening mechanisms that explain the crush resistance of the aptly named diabolical ironclad beetle. The observations could be applied in developing tough, impact- and crush-resistant materials for joining dissimilar materials. Read more »
X-Rays Reveal Architectural Clues to the Crush-Resistance of Diabolical Ironclad Beetles
The appropriately named diabolical ironclad beetle has an incredibly crush-resistant exoskeleton, which could serve as a blueprint for tougher materials. To see, in microscopic detail, what makes the beetle so uniquely ironclad, researchers used the ALS to explore a protective covering known as the “elytra,” its abdomen, and other parts. Read more »
Design and synthesis of high performance flexible and green supercapacitors made of manganese‐dioxide‐decorated alkali lignin
Researchers synthesized a plant‐based composite electrode for use in flexible supercapacitors and used synchrotron x‐ray microtomography to better understand the impact of microstructure and morphology on electrode porosity and electrical conductance. Read more »
Battery Breakthrough Gives Boost to Electric Flight and Long-Range Electric Cars
While lithium metal extends an EV’s driving range, it also shortens the battery’s useful life due to lithium dendrites that can cause short circuits. Researchers report a new class of soft, solid electrolytes—made from both polymers and ceramics—that suppress dendrites, before they can propagate and cause the battery to fail. Read more »
Porous Electrolyte Frameworks for All-Solid-State Batteries
With the help of microtomography at the ALS, researchers developed a method to produce a porous electrolyte framework that they used to construct a working all-solid-state battery. Such batteries potentially offer a higher energy density, longer cycle life, and better inherent safety than state-of-the-art lithium-ion batteries. Read more »
Direct Imaging of Fracture Closure in Reservoir Shales
Using x-ray microtomography at the ALS, researchers identified and characterized the microscale factors affecting fluid flow through shale fractures propped open with sand or ceramic spheres. A better understanding of propped fractures can lead to safer and more efficient recovery of hard-to-reach oil and gas resources. Read more »
The Chemistry of Art
To learn more about the chemical processes involved in aging oil paints in microscopic and nanoscale detail, researchers conducted a range of studies that included 3D x-ray imaging of a paint sample. The study could have broader implications for conservation based on the observed chemistry of oil paints. Read more »
The Stomatopod Telson: Convergent Evolution in the Development of a Biological Shield
In this article, researchers identify multiscale structure‐mechanical property relationships within the shield-like exoskeletal telson structure of the mantis shrimp, used for defense and protection. Comparison of telsons from two evolutionarily divergent species reveal differences in macromorphology, cuticle thickness, and mineralization, imparting compressive stiffness as well as compliance for energy absorption.
