Researchers have found a new way to control magnetism at the atomic level that will serve as a model for studying emergent phenomena in other systems. The ability to engineer and tune properties on such small length scales can (eventually) enable us to design exciting new magnetic devices. Read more »

The Smectic Phase of DNA “Nano-Nunchaku”
Researchers designed DNA sequences that self-assemble into a nanoparticle about 50 nm long, composed of two double-stranded DNA duplexes linked together by a single-stranded DNA filament. The nanoparticle resembles nunchaku—a traditional weapon of several martial arts—but 30 million times smaller. Read more »
Chemistry on the Edge: Study Pinpoints Most Active Areas of Reactions on Nanoscale Particles
Experiments confirm that structural defects at the periphery are key in catalyst function. The SINS study is an important step in chronicling how the atomic structure of nanoparticles impacts their function as catalysts in chemical reactions. Read more »
New Multiferroic Material for Ultralow-Power Electronics
Scientists paired ferroelectric and ferrimagnetic materials so that their alignment can be controlled with a small electric field at near room temperatures, a major step in the development of ultralow-power microprocessors, storage devices, and next-generation electronics. Read more »
Exploring the Structure of Aqueous Solutions with SALSA
Researchers have published a series of papers that open up the possibility of probing hydrogen bonds in aqueous solutions by combining x-ray emission spectroscopy and resonant inelastic soft x-ray scattering, using the specialized Solid and Liquid Spectroscopic Analysis (SALSA) endstation at Beamline 8.0.1.

X-Rays Help Evaluate Quality of 3D-Printed Repairs
Laser 3D printing is a promising way to repair machine parts (such as jet-engine turbine blades) made of single-crystal superalloys. But microstructural inhomogeneities created by the high-power laser are a major reliability concern, so researchers employed x-ray Laue microdiffraction to probe the microstructure. Read more »
Fernando Sannibale, Division Deputy for Accelerator Operations and Development
Fernando Sannibale, previously the principal investigator of the Advanced Photoinjector Experiment (APEX) at LBNL, has recently taken on a new role as leader of the ongoing ALS Accelerator Physics program in the Accelerator Technology and Applied Physics Division and will also serve as the ALS Division Deputy for Accelerator Operations and Development. We recently sat down with Sannibale to talk about his years at the ALS and what he hopes to accomplish in his new role. Read more »
A New Way to Determine the 3D Structure of Molecules
Researchers have created a sort of nanoscale display case that enables new atomic-scale views of hard-to-study chemical and biological samples. The work could help to reveal new structural details for a range of challenging molecules by stabilizing them inside sturdy structures known as metal-organic frameworks (MOFs). Read more »
3D Visualization of the Behavior of Grease Additives
Lubricants help keep civilization running smoothly, but is there room for improvement? With the goal of increasing the life span and lowering the costs of all kinds of mechanical and biological systems, researchers used x-ray microtomography to visualize the behavior of grease additives under working conditions.
