HP Labs researchers have tackled a decades-old mystery relying on powerful ALS microscopy techniques—to better understand the fourth basic circuit element: the memristor. The memristor (short for “memory resistor”) joins the other passive elements—the capacitor, the resistor, and the inductor—to create a device with the ability to “remember” changes even when it loses power. Commercial development based on memristors offers the promise of computing systems with highly advanced energy efficiency and memory retention. Memristor-based memory could be a strong competitor for current flash memory.

Crystallographic Consulting has a varied client base that includes many of the participating research team (PRT) members at the Berkeley Center for Structural Biology (BCSB), which operates five ALS beamlines. Crystallographic Consulting also contracts beam time for another 10-12 companies. Most of their research supports pharmaceutical companies working on new treatments for metabolic diseases and cancer.

Alternatives to the current lithium-ion-based car batteries are at the forefront of the automotive industry’s research agenda—manufacturers want to build cars with longer battery life, and to do that they’re going to have to find new solutions. One promising battery material is magnesium (Mg)—it is more dense than lithium, it is safer, and the magnesium ion carries a two-electron charge, giving it potential as a more efficient energy source. Magnesium has a high volumetric capacity, which could mean more battery power in a smaller space. However, to bring Mg batteries to the commercial market, researchers must create new electrolytes with improved properties. The x-ray absorption spectroscopy (XAS) facilities at the ALS are vital to understanding the interfaces and active species in Mg batteries.

Understanding “whisker” growth—the spontaneous growth of long filament-like grains on the leads, or “legs,” of electronic components—is key to manufacturing reliable lead-free electrical and electronic equipment. Cisco Systems, one of the world’s largest networking equipment producers, has provided funding and technical support to a group of ALS users from Purdue University to research the mechanism and driving forces for whiskers, with the ultimate goal of defining effective mitigation measures.

With an increased demand for sustainable structures and efficient material use, the building industry is always looking for ways to extend their resources. Wood composites offer an opportunity to do this, saving building costs and in some cases increasing strength and durability. Researchers have used data gathered at the ALS to build a predictive computer simulation model that will provide insight into how certain wood species and adhesive types will interact. Technological advances are contributing to stronger, environmentally friendly composite materials that can be used in wood products such as furniture components or building materials.
