Scientists have designed a new material system to overcome one of the biggest challenges in recycling consumer products: mixed-plastic recycling. Their achievement will help enable a much broader range of fully recyclable plastic products and brings into reach an efficient circular economy for durable goods like automobiles. Read more »
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 »
Biomineralization: Integrating mechanism and evolutionary history
In this review, Gilbert et al. develop a model for calcium carbonate biomineralization applicable to all phyla. Their model may help elucidate the key genetic components that drive biomineralization and offers insight into the consequences of global climate change on marine organisms. Read more »
Loss of biological control of enamel mineralization in amelogenin-phosphorylation-deficient mice
Amelogenin phosphorylation plays crucial roles in controlling structural, crystallographic, mechanical, and compositional characteristics of dental enamel. Thus, loss of amelogenin phosphorylation leads to a reduction in the biological control over the enamel mineralization process. Read more »
New Device Advances Commercial Viability of Solar Fuels
A Berkeley Lab research team developed a new artificial photosynthesis device component that exhibits remarkable stability and longevity as it selectively converts sunlight and carbon dioxide into two promising sources of renewable fuels—ethylene and hydrogen. Read more »
A Split-Screen View of Solar-Cell Crystallization
Researchers simultaneously monitored both the structure and function of a photovoltaic material as it crystallized from solution. The work raises the prospect of rationally tuning materials for optimal performance in photovoltaics and other light-manipulating devices, including light-emitting diodes, detectors, and lasers.

New Technique Paves the Way for Perfect Perovskites
A new solar material, organic-inorganic halide perovskites, could one day help the U.S. achieve its solar ambitions and decarbonize the power grid. A recent study reports that manufacturing could be aided by a new instrument that uses invisible x-ray light and visible laser light to probe a perovskite material’s crystal structure and optical properties as it is synthesized.

When Timing Isn’t Everything: Spontaneous Chemical Dynamics
Researchers combined aspects of x-ray photoelectron spectroscopy (XPS) with correlation spectroscopy—a statistical method capable of detecting patterns in microscopic fluctuations across space and time. The new technique, called time-correlation XPS, allows researchers to monitor dynamics without the need for a timed trigger. Read more »
Exquisitely Selective CO2 Reduction on Silver
Researchers electrochemically reduced CO2 to CO with nearly perfect selectivity over other products by adding an organic compound to the surface of a silver electrode. With theoretical analyses and ALS data, the work revealed the key role of the microenvironment in promoting the conversion of CO2, a greenhouse gas, into useful products. Read more »
Chemical (and Strategic) Transformations at Beamline 9.0
The Chemical Dynamics beamline, used for gas-phase vacuum ultraviolet (VUV) experiments, was one of the first beamlines built at the ALS. Since then, the program has undergone several strategic transformations, enabling the study of complexity in clusters, aerosols, and nanoparticles using both VUV and soft x-ray radiation. Read more »
