ALS Work Using Microscopy/Imaging

These techniques use the light-source beam to obtain pictures with fine spatial resolution of the samples under study and are used in diverse research areas such as cell biology, lithography, infrared microscopy, radiology, and x-ray tomography.

 

Removing Nitrogen from Wastewater using Horizontal Levees

Treated municipal wastewater often contains nitrogen, which has been linked to algal blooms that can devastate coastal ecosystems. In a recent study, researchers characterized the primary nitrogen-removal pathways in a horizontal levee, an engineered subsurface water-treatment system consisting of a gently sloping strip of land adjacent to storm-control levees.

A Machine-Learning Approach to Better Batteries

Researchers extracted the relationship between strain and composition in a battery material by applying machine-learning methods to atomic-scale images. The work could lead to more durable batteries and also highlights the potential of integrating microscopy techniques with machine learning to gain insights into complex materials.

Key to Coral Resilience Is Faster Skeletal Crystallization

In a new study, researchers show that the crystallization rate of coral skeletons differs across species and is correlated with their resilience to ocean acidification. The results have implications for predicting coral reef survival and developing mitigation strategies against having their bony skeletons weakened by ocean acidification. Read more »

Structural organization of the spongy mesophyll

Many leaves have two layers of photosynthetic tissue: the palisade and spongy mesophyll. The latter is not well characterized and often treated as a random assemblage of irregularly shaped cells. These results show that simple principles may govern the organization and scaling of the spongy mesophyll in many plants and demonstrate the presence of structural patterns associated with leaf function.

How X-Rays Can Make Better Batteries

In order to help our nation meet its goal of net-zero carbon emissions by 2050, scientists like William Chueh and David Shapiro are working together to come up with new strategies to design safer, long-distance batteries made from sustainable, Earth-abundant materials. They discuss their pioneering work in this Q&A. Read more »

Safely Studying Dangerous Infections Just Got a Lot Easier

Researchers have cranked up the speed of imaging infected cells using soft x-ray tomography, a technique that can generate incredibly detailed, three-dimensional scans. The approach gives an easy way to quickly examine how cells’ internal machinery responds to SARS-CoV-2, or other pathogens, as well as how the cells respond to drugs designed to treat the infection.

Rapid 3D Visualization of Lung Cells Altered by SARS-CoV-2

In this work, researchers illustrated the potential of soft x-ray tomography to rapidly characterize and quantify the structural changes induced in cells infected by SARS-CoV-2, revealing profound alterations of the subcellular architecture induced by viral infection over time. Read more »
