Designing Selective Membranes for Batteries Using a Drug Discovery Toolbox

Researchers designed a polymer membrane with molecular cages built into its pores that hold positively charged ions from a lithium salt. These “solvation cages” increased lithium-ion flow by an order of magnitude and could allow high-voltage battery cells to operate at higher power and more efficiently, important for both electric vehicles and aircraft.

Coral Skeleton Reveals Hidden Structures under Multimodal Scrutiny

A powerful new microscope combining ptychography with x-ray linear dichroism provides nanoscale insight into the biomineral strength and resilience of a coral skeleton. The technique’s previously unachievable spatial resolution and contrast will open up new lines of research for users of x-ray microscopy at the ALS. Read more »

To Speed Discovery, Infrared Microscopy Goes “Off the Grid”

Researchers developed a highly efficient way to collect infrared microscopy data that avoids the use of slow, grid-based raster scans. The method substantially reduces image-acquisition times by autonomously increasing sampling density in regions of interest, facilitating infrared spectromicroscopy of biochemical processes in real time.

Stacking the Deck for Custom-Built Hybrid Materials

Researchers fabricated an electronically coupled heterostructure from a novel semiconducting 2D polymer and a 2D transition metal dichalcogenide. Dramatic optical and electronic changes emerged as polymer thickness decreased, underscoring the potential for the discovery of emergent phenomena in studies of hybrid heterostructures. Read more »

Molecular Complex Removes Copper Ions from Water

X-ray analyses provided key insights into the copper uptake mechanisms in a new organic-inorganic hybrid material that quickly and selectively removes copper ions from water. The material provides an efficient tool for copper remediation as well as a blueprint for creating other hybrid materials for removing toxic metals from water. Read more »PPT-icon-35 PDF-icon-35

Speeding Toward Improved Hydrogen Fuel Production

Researchers synthesized a material that speeds up one of the limiting steps in extracting hydrogen from alcohols. The catalyst cleanly and efficiently accelerates the removal of hydrogen atoms from a liquid chemical carrier. The material is robust, made from earth-abundant metals, and will help make hydrogen a viable energy source for a wide range of applications. Read more »

Super-Resolution Measurement of X-Ray Mirrors

ALS researchers, in collaboration with software and nanofabrication small businesses, developed a way to improve the accuracy of instruments that measure the surfaces of x-ray mirrors. The work significantly improves the quality of the data needed for the fabrication and optimal performance of advanced x-ray beamlines and space telescopes. Read more »PPT-icon-35 PDF-icon-35

Scientists Design New Framework for Clean Water

A promising solution to water pollution from abandoned copper mines relies on materials that adsorb copper ions from wastewater, but commercially available products lack the required chemical specificity and load capacity. A team of scientists has designed a new crystalline material that targets and traps copper ions from wastewater with unprecedented precision and speed. Read more »

Coming Down the Pike: Long-Haul Trucks Powered by Hydrogen Fuel Cells

DOE has announced several major investments to take hydrogen fuel cells to the next level, and Berkeley Lab is set to play a leading role. Ten DOE national labs have been selected to participate in two new consortia and a third continuing one to improve the durability, lifetime, and efficiency of fuel cells. Read more »
