When you use a membrane for water treatment, junk builds up on the membrane surface—a process called fouling—which makes the treatment less efficient. In this work, researchers studied how membranes are fouled by interactions between natural organic matter and positively charged ions commonly found in water. Read more »

Coaxing Molecules to Stand Tall for Better Solar Cells
Multimodal probes revealed a way to prevent the formation of undesirable phases in a perovskite-type compound that shows promise for the efficient harvesting of light for solar cells. The work led to new fabrication protocols that resulted in devices with improved power-conversion efficiencies and operational stability. Read more »
Beamline Optics and Modeling School (BLOMS) 2023
The ALS hosted its first Beamline Optics and Modeling School (BLOMS 2023), a three-day, hands-on workshop to teach the theory, methods, strategy, and tools used to design and model x-ray beamlines. Experts from four other light sources and one private company showed students the capabilities of modern, freely available tools for x-ray source and beamline modeling. Read more »
Breaking Barriers in Drug Delivery with Better Lipid Nanoparticles
A collaboration between Berkeley Lab and Genentech, a member of the Roche Group, is working to break through some of the drug delivery bottlenecks by designing the most effective lipid nanoparticles (LNPs)—tiny spherical pouches made of fatty molecules that encapsulate therapeutic agents until they dock with cell membranes and release their contents.

Toward High Efficiency Water Processed Organic Photovoltaics: Controlling the Nanoparticle Morphology with Surface Energies
Researchers achieve power conversion efficiencies approaching 10% by careful control of the nanoparticle and thin film morphologies thanks to surface energy considerations. This approach opens the route to low environmental footprint photovoltaics. Representing the promise of this sustainable direction in organic photovoltaics, the image shows the deposition of the active layer from water-based nanoparticles inks. Read more »
Allosteric Tuning of Caspase-7: Establishing the Nexus of Structure and Catalytic Power
How can allosteric sites be more effectively targeted by small-molecule drugs? Using an integrated in vitro/in silico experimental workflow; we discovered novel allosteric inhibitors of caspase-7 and revealed new connections between the active site and the remote allosteric site (i. e., allosteric structure–activity relationships, ASARs) for this valuable disease target.

A Molecular-Scale Understanding of Misorientation Toughening in Corals and Seashells
Researchers reveal that the toughness of polycrystalline seashells and coral skeletons is increased by small misorientation of adjacent crystals. The findings pave the way toward bioinspired materials with tunable toughness. Read more »
