Humans have drawn technological inspiration from fish scales going back to ancient times: Romans, Egyptians, and other civilizations would dress their warriors in scale armor, providing both protection and mobility. Now, scientists have characterized carp scales down to the nanoscale, enabling them to understand how the material is resistant to penetration while retaining flexibility. Read more »

On-Off Switch for Regulating Tumor-Cell Growth
The mechanisms that affect the regulation of cell growth in certain tumor cells were revealed by a Genentech study of enzyme structures, conducted in part at the ALS. The work establishes a framework for the rational discovery of new therapeutics to improve upon currently existing treatments for certain cancers. Read more »
Energetics and Energy Loss in 2D Ruddlesden–Popper Perovskite Solar Cells
Qinye Bao and co‐workers systematically investigate the energetics and energy loss in 2D Ruddlesden‐Popper perovskite (RPP) solar cells. The crucial scenario found at the 2D RPP/electron transport layer interface is that the potential gradient across ligands promotes separation of the photogenerated carrier, with electrons transferring from the perovskite crystal to the electron transport layer.

How a Cancer Drug Targets Proteins for Degradation
Protein structures obtained by Novartis researchers helped reveal how a cancer drug promotes the degradation of proteins essential to cell proliferation. A detailed understanding of the drug’s mechanism of action is key to determining whether the protein-degradation system can be reprogrammed to degrade different targets. Read more »
The Bottleneck Step of a Complex Catalytic Reaction
The rate-limiting step in catalysis involving oxygen uptake was identified through analysis of the reaction pathways and observations performed under operating conditions. The work lays the foundation for improving the efficiency of energy conversion and storage devices such as fuel cells, catalytic reactors, and batteries. Read more »
Controlling antiferromagnetic domains in patterned La0.7Sr0.3FeO3 thin films
Antiferromagnetic spintronics have gained interest because they can be controlled at terahertz frequencies and are insensitive to external magnetic fields. Due to dimensional confinement as well as microstructuring by ion implantation, the spin axis of an antiferromagnetic oxide can be robustly controlled in a deterministic way up to room temperature.

Jin Qian, Theoretical and Computational Chemistry Postdoc
As a theoretical chemist, Jin Qian builds “virtual universes” that help predict what experimental chemists will see in their research. She focuses on water formation, a theme that carries through to one of her hobbies, which she is sharing with us in this month’s postdoc profile. Read more »
May 2020 Message from the User Office
Berkeley Lab is planning to gradually bring staff back onsite, consistent with federal, state, and local guidance. These plans will begin on June 1 with a small on-site pilot group. We expect a few limited activities at the ALS to be part of this pilot. Once the ALS schedule for the 2020-2 cycle has been published, we will develop a detailed plan for allocating beamtime to proposals. We are exploring how each beamline can set up remote operations to support user experiments while staff maintain social distancing. Read more »
May 2020 Message from the UEC
We are working on making the 2020 User Meeting, which will now take place as an online meeting on August 25–28, as rich and productive as our user meetings normally are. We will announce more details over the next few months. If you wish to nominate someone for one of the awards below, please remember the deadline is June 1. Read more »
A Scalable Platform for Two-Dimensional Metals
Using a new method for stabilizing a two-dimensional (2D) metal on a large-area platform, researchers probed the origins of the material’s superconductivity. The work represents a notable milestone in advancing 2D materials toward broad applications in topological computing, advanced optics, and molecular sensing. Read more »
