Manganese Cathodes Could Boost Lithium-ion Batteries
Rechargeable lithium-ion batteries are used in mobile devices, electric vehicles, and energy storage systems. But supplies of nickel and cobalt, commonly used in the cathodes of these batteries, are limited. New research opens up a potential low-cost, safe alternative in manganese, the fifth most abundant metal in the Earth’s crust. Read more »
Electronic energy transfer ionization in naphthalene–CO2 clusters reveals excited states of dry ice
The interaction between CO2 and polycyclic aromatic hydrocarbons is of interest in astrochemically relevant ices, the transition to renewable energy, and the development of green chemistry. We investigate the VUV excitation of the naphthalene–CO2 complex and observe excited states of CO2 through a newly identified electronic energy transfer ionization mechanism. Read more »

2024 User Meeting Highlights
Another successful ALS User Meeting was held August 12–14, bringing the ALS user community together under the sunny summer skies of Berkeley, California. Over 300 participants enjoyed an engaging program organized by the Users’ Executive Committee (UEC), led by User Meeting organizers Wendy Gu, Devin Grabner, Monsuru Ramoni, and Shan Wu. Read more »
A Promising Compound for Reversible Male Contraception
Researchers found that a small-molecule protein inhibitor—screened from billions of compounds and analyzed using structural insights from protein crystallography—reversibly suppresses male fertility in mice. The work addresses the pressing need for more contraceptive options that enable all individuals to control their own fertility. Read more »
A New Way to “Squeeze” Infrared Light Down to Size
Researchers demonstrated a new way to confine, or “squeeze,” infrared light by coupling photons with phonons (lattice vibrations) within a certain type of thin film. The work heralds a new class of optical materials for controlling infrared light, with potential applications in photonics, sensors, and microelectronic heat management. Read more »
Postdoctoral Fellowship Application Window to Open in October
Applications for the next round of ALS Collaborative Postdoctoral Fellowships are due November 1 for a start date of May 1, 2025. Fellows spend a year in residence at the ALS pursuing research projects in teams that include staff and the user community, and are exposed to current scientific challenges that can be tackled using advanced synchrotron radiation tools.
