Updated 2023-1 Operating Schedule

The operating schedule for the 2023-1 cycle has been updated. The next long shutdown is expected to begin in January 2023 and last until early February (shorter than originally planned). The most up-to-date information on the current schedule and future outlook can always be found on the Operating Schedule web page. Read more »

Watching Nanoparticle Chemistry and Structure Evolve

Using a multimodal approach, researchers learned how chemical properties correlate with structural changes during nanoparticle growth. The work will enable a greater understanding of the mechanisms affecting the durability of nanoparticles used to catalyze a broad range of chemical reactions, including clean-energy reactions.

Distinguishing Nanoparticles from Gas-Phase Species in Reacting Flows

Researchers developed a strategy for distinguishing between gas-phase species and newly formed nanoparticles in mixed gas- and particle-phase reacting flows. The approach uses small-angle x-ray scattering to study particle formation as it occurs by explicitly accounting for temperature-dependent scattering from gases. Read more »PPT-icon-35

Optical sensing of aqueous nitrate anion by a platinum(II) triimine salt based solid state material

Researchers present a new Pt(II) salt that enables the selective and quantitative measurement of aqueous nitrate anions without the need for pH adjustment. The method relies on the color change of the Pt(II) complex from yellow to red and an intense luminescence response, simplifying the detection process for on-site applications and expanding its applicability to broader matrices.

Protein Assemblies Show Surprising Variability

Protein-structure studies performed in part at the ALS helped researchers discover that the protein assemblies in a key carbon-cycling enzyme can rearrange with surprising ease. The findings raise the prospect of genetically tuning the protein in agricultural plant species to produce more productive and resource-efficient crops. Read more »PPT-icon-35 PDF-icon-35

Valence tautomerism in a cobalt-verdazyl coordination compound

Valence tautomerization in inorganic chemistry typically involves the distribution of electrons between a metal center and redox active ligand, with potential application as molecular switches or other molecular devices. Here we report an example of valence tautomerization and an unusual electronic structure in a cobalt verdazyl complex. Read more »
