Researchers found that compressing hybrid (organic–inorganic) semiconductors significantly boosts their conductivity. The work demonstrates a novel doping mechanism in which the material’s organic molecules serve as charge reservoirs for tuning charge-carrier concentration, with promising applications in solar cells, lasers, and LEDs.

Molecular Switch Triggers Changes in Plant Structure
Using x-ray crystallography, biochemistry, and plant genetics, researchers identified a molecular switch that triggers modifications to plant structure in response to environmental conditions. A greater understanding of this adaptive process will help scientists optimize plants for efficient nutrient uptake and resistance to parasitic species. Read more »
New Insight into Titan’s Hazy Atmospheric Chemistry
Researchers simulated the complex chemistry that may be occurring in the hazy atmosphere of Saturn’s largest moon, Titan, and analyzed the reaction products at the ALS. The work provided new insights into what future Titan probes may encounter upon arrival and what the atmosphere of Earth may have been like eons ago. Read more »
Operando Study of CO2 Reduction by Copper Nanoparticles
Since copper is necessary to catalyze the reduction of CO2, a greenhouse gas, to valuable products, scientists are working hard to improve its selectivity and activity. Now, researchers have developed an operando capability that can help in this effort by simultaneously probing chemical valence and interparticle dynamics. Read more »
Jinghua Guo to Receive the 2022 Shirley Award
ALS senior scientist Jinghua Guo is the recipient of this year’s Shirley Award for Outstanding Scientific Achievement at the ALS. Guo is being recognized for pioneering the development of operando soft x-ray spectroscopy, work that’s enabled studies under realistic conditions, which is of great importance in environmental and energy research.
