Label-Free Characterization of Organic Nanocarriers

A technique developed at the ALS enables accurate characterization of organic nanocarriers (molecules that encapsulate other molecules) without the need for disruptive labeling. The method will enable faster, more precise development of exciting new technologies, ranging from targeted drug delivery to oil-spill remediation. Read more »PPT-icon-35 PDF-icon-35

Tuning Semimetallicity Using Thin Films and Interfaces

With support from ALS data, scientists gained new insight into a semimetal’s unusual electronic behavior. The work lays out a basic strategy for engineering the band structures of semimetallic compounds using dimensional confinement and reveals a new way of creating two-dimensional electron/hole gases by exploiting interfacial bonding.

Mineral Microstructures Shed Light on Planet-Scale Dynamics

To explore what happens to minerals under the extreme conditions in Earth’s mantle, researchers developed an x-ray technique that bridges the gap between methods that reveal bulk properties and those that focus on individual crystals. Use of the technique has shed light on the dynamics of tectonic-plate subduction in Earth’s lower mantle. Read more »

Researchers Set Sights on Another COVID-19 Target

Early in the COVID-19 pandemic, it was quickly established that the receptor binding domain (RBD) of the SARS-CoV-2 spike protein is a prime target for neutralizing antibodies. Now, scientists have found a second region of the spike protein that is targeted by dozens of antibodies, some of which exhibit ultrapotent neutralizing activity. Read more »

Alpha N’Diaye, Research Scientist

Alpha N’Diaye first came to Berkeley Lab as a postdoc, but his interest in Berkeley was piqued far earlier. Find out what inspired teenage Alpha, and what keeps him here to this day. Read more »

Survey on Remote Access

The ALS and the Users’ Executive Committee would like to better understand the impact this past year’s restrictions had on the user community as well as seek suggestions on possible improvements that would facilitate future beamtime. We request your input on this remote access survey by July 30. Read more »

Register for the 2021 User Meeting (August 10–13)

This year’s User Meeting features, for the first time, a Nobel panel (and Q&A) with Ada Yonath and Stanley Whittingham. Bookmark workshops and tutorials that interest you so that the organizers know how many participants to expect. Remember: the student poster competition and general poster session are first come, first served! Read more »
