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 »
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 »
June 2023 Message from the UEC
UEC Chair Inna Vishik discusses the format for this year’s User Meeting, which will include tutorials, plenary and poster sessions, and workshops focused on long-term scientific visioning.

Excitons Dance the Two-Step in a 2D Material
Excitonic insulators are a rare form of macroscopic quantum state that can be realized at a high temperature, which can be useful for quantum information science. At the ALS, researchers found that in a 2D material, a novel two-step “folding” behavior in the ARPES data signals the existence of an intermediate exciton gas state. Read more »
Surface Engineering Boosts Water-Splitting Efficiency
Researchers modified the surface of an electrocatalyst to maximize its efficiency at splitting water. The optimized material is approximately 40 times more efficient than similar commercial electrocatalysts and could help make the production of clean hydrogen fuel more sustainable and economical.

Congratulations to Our 2023 Retirees
Gary Giangrasso, David Malone, and Troy Stevens Sr. are retiring after a combined 94.25 years of service. Thank you all for your contributions to the ALS, and congratulations on your retirement! Read more »
Chiral Twists and Turns Lead Way to New Materials
Researchers found that, in crystals with structural chirality (left- or right-handedness), tuning the electronic behavior reveals hidden chiral phases and singularities. The results provide a new way to predict, test, and manipulate novel materials that exhibit desirable properties for next-generation electronic and spintronic devices. Read more »
