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.

Absorber Captures Excess Chemotherapy Drugs
Researchers have designed a biomedical device for absorbing excess chemotherapy drugs during cancer treatment, characterizing the active surface layer using x-ray microtomography. The work opens up a new route to fighting cancer that minimizes drug toxicity and enables personalized, targeted, high-dose chemotherapy. Read more » 
Comparative morphology of cheliceral muscles using high‐resolution X‐ray microcomputed‐tomography in palpimanoid spiders
Spiders are important predators in terrestrial ecosystems, yet we know very little about their principal feeding structures—the chelicerae—an extremely important aspect of spider biology. Here, using micro‐Computed‐Tomography scanning techniques, researchers perform a comparative study to examine cheliceral muscle morphology in six different spider specimens. Read more »
TE Connectivity Uses ALS to Improve Conductive Plastics
TE Connectivity used ALS microtomography capabilities to optimize the material and manufacturing parameters of their conductive plastics to impart good electrical conductivity. Conductive plastics with good electrical properties offer processing and cost benefits over metal alternatives, with applications ranging from automotive to data communications. Read more »
The Microstructure of a Parrotfish Tooth Contributes to Its Toughness
Parrotfish chew on coral, producing hundreds of pounds of sand each year. Mapping the microstructure of parrotfish teeth, scientists found bundles of crystals interwoven like chain mail. The results provide a blueprint for creating ultra-durable materials for mechanical components that undergo repetitive contact, movement, and abrasion. Read more »
