Researchers engineered protein-like polymers that replicate complex enzyme functions. This work, which was verified using X-ray characterization techniques at the Advanced Light Source (ALS), offers a cost-effective, scalable approach that paves the way for functional materials in biomedicine, energy, and manufacturing.

📸 Schematic comparing the global folding patterns, chemical structures, and active sites of a) natural protein demonstrating a rigid secondary structure of regular, local folding patterns in the chain of amino acids; and b) the protein-like polymers created in this study, which do not form secondary structures but instead adopt varying conformations based on the hydrophobic (water-repelling) properties of segments in the chain. Red, grey, blue and yellow correspond to very hydrophobic, hydrophobic, hydrophilic (water-loving) and very hydrophilic amino acid residues, respectively. The chemical structures of key functional residues are shown in the inset boxes. (Credit: Ting Xu/UC Berkeley/LBNL)

Berkeley Lab researchers developed a new x-ray technique that uses nanoscale patterns to amplify weak signals, allowing scientists to observe chemical reactions at buried solid–liquid interfaces that were previously challenging to study. Read more: https://lnkd.in/grG4g36R

📷 In pattern-enhanced RSoXS, repeating scattering elements in the sample coherently amplify soft x-ray signals. In this work, nickel electrodes patterned with an array of nanoscale structures are integrated into an operando electrochemical flow cell, allowing researchers to monitor subtle chemical changes at the buried electrode–electrolyte interface during the oxygen evolution reaction.

X-ray microscopy tools at the ALS and Stanford Synchrotron Radiation Lightsource mapped the chemical changes inside wildfire ash particles, revealing that pyrogenic iron and manganese gradually disappeared as the soil recovered. These findings shed light on how wildfires drive transient mineral formation that impacts micronutrient cycling and soil resilience, with implications for landscape recovery strategies.

📷 Wildfires are becoming more common in the western United States. Experiments at the ALS are showing how they influence nutrient cycling and soil recovery. Shortly after the fire, an ash layer containing various forms of iron (Fe) and manganese (Mn) covered the surface soil. Two years later, these Fe and Mn forms are absent. Understanding chemistry changes like these is vital for informing land management practices for ecosystem recovery. (Credit: Kyounglim Kang and Jasquelin Pena/UC Davis).

Researchers used synchrotron infrared nanospectroscopy (SINS) at the ALS to detect the molecular behaviors of ionic liquids—which serve as high performance electrolytes in energy storage devices—under varying charge bias conditions. Their insights define a direction for targeted design of ionic liquid-based electrolytes with optimized properties for energy storage applications.

Machine learning tools and experiments at the ALS enabled the identification of defect-rich regions in single-crystalline Co3Sn2S2 that link to how surface electrons move. Atom-level understanding of how the surface electronic properties of a magnetic semimetal can be tuned could guide its use in advanced technologies like spintronics and catalysis.

Researchers used scanning transmission x-ray microscopy at the ALS to analyze Arctic aerosols, which strongly influence cloud formation and overall climate. Understanding what these particles are and how they change as they travel could help improve climate models and yield more accurate predictions of the changing Arctic environment’s global impact.
