Three SCGSR Awardees to Conduct Research at the ALS (May 2023)

The Office of Science Graduate Student Research (SCGSR) program will provide Alaina Hartnett (Harvard University), Mostafa Nassr (UT Austin), and Sreevishnu Oruganti (UIUC) with supplemental awards to conduct research at the ALS in areas that address scientific challenges central to the Office of Science mission.

Synergistic Effect Could Boost Production of Green Hydrogen

Researchers developed a composite material of earth-abundant elements that catalyzes the production of green hydrogen much more effectively than similar homogeneous compounds. The composite could potentially be used for efficient hydrogen generation without the need for rare and precious metals like platinum. Read more »

Kristin Carrillo, Senior Material Specialist

Kristin Carrillo’s many tasks around the ALS may be a divergence from her degree in psychology and her previous life as a softball player, but the connecting thread is the relationships she’s developed with the people around her. Find out more about her work as a material specialist and how she supports the scientific mission of the ALS. Read more »

Increasing the Energy Density of Hybrid Supercapacitor Electrodes

Hybrid supercapacitors (HSCs) integrate the merits of batteries with those of supercapacitors. However, the fraction of active material in HSC electrodes has remained too low for commercial requirements. Now, researchers have found a clever way to increase the active-mass ratio to achieve dramatic improvements in key measures. Read more »

Nicotine Protonation in Simulated Vaping Aerosols

To better understand how e-cigarette additives alter nicotine chemistry and users’ perceptions of vaping, researchers used x-ray spectroscopy technology at the Advanced Light Source to analyze the acid-base equilibria of additive-enhanced nicotine in simulated vaping aerosols. Read more »

ALS User Forum: A Time for Cookies with Colleagues

The place, frequency, and snack selection might have changed over the years, but Cookie Time has always been a way for the ALS community to gather. In its current incarnation, different groups contribute their favorite snacks, and all are welcome to mingle each Thursday at 3 p.m. Read more »

Extreme Closeup of Copper Electrocatalysts in Action

Researchers at Berkeley Lab have made real-time movies of copper nanoparticles as they evolve to convert carbon dioxide and water into renewable fuels and chemicals. Their new insights could help advance the next generation of solar fuels. Read more »

Gemini Beamline 2.0.1 Banks Its First Protein Structure

A protein structure obtained from ALS Beamline 2.0.1 (“Gemini”) has recently been published in the literature and deposited into the Protein Data Bank (PDB)—two significant firsts for this beamline. The structure helped provide new insights into the molecular mechanisms involved in triggering certain inflammatory diseases. Read more »

Doped Nickelate Enters a New Phase with Spintronics Potential

Rare-earth nickelates are known to undergo a metal-to-insulator phase transition as temperature decreases, the mechanism of which is not well understood. Here, researchers observed a new low-temperature phase that’s both metallic and antiferromagnetic—an unusual combination with potential value in spintronics. Read more »
