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 »

Impact of Thermal Stress on Device Physics and Morphology in Organic Photodetectors
Implementing organic photodetectors (OPDs) into Si-based manufacturing process requires high thermal resistance. This work showcases a comprehensive picture of the impact of high thermal stress (at 200 °C, up to 2 hours) on photosensing performance, bulk and interfacial morphologies, and device physics.

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 »
Spiraling Beams Differentiate Antiferromagnetic States
Using spiraling x-ray beams, researchers differentiated between energetically equivalent (“degenerate”) states in an antiferromagnetic lattice. The work shows the potential of these beams to probe properties that would otherwise be inaccessible, to better understand phenomena of fundamental interest and for applications such as spintronics.

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 »
Probing Walls between Electrically Polarized Domains
Researchers used infrared light to investigate the properties of the domain walls that separate electrically polarized (ferroelectric) regions in a rare-earth ferrite material. An understanding of domain-wall behavior is relevant to the development of advanced logic and memory applications for ultralow-power digital devices. Read more »
Vertical Gradient of Size-Resolved Aerosol Compositions over the Arctic Reveals Cloud Processed Aerosol in-Cloud and above Cloud
Vertical distribution of size-resolved chemical composition of Arctic aerosol particles was investigated in different cloud layers. Multimodal microspectroscopy analysis reveals a broadening of chemically-specific size distribution above the cloud top. 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 »
