Burning of natural gas at oil and gas wells, called flaring, is a major waste of fossil fuels and a contributor to climate change. In this work, researchers synthesized and characterized a metal-organic framework that uses biomimetic chemistry to convert wellhead gases into economically valuable feedstocks for petrochemical products.

Flat Bands Signal Electrons Trapped in 3D
Researchers found flat electronic band structures—known hallmarks of electrons trapped in two dimensions—but in a material that extends this phenomenon to three dimensions. The work opens up a material framework for exploring superconductivity and other exotic states in three dimensions for advanced electronic applications. Read more »
Correlating Conformational Equilibria with Catalysis in the Electron Bifurcating EtfABCX of Thermotoga maritima
Anaerobic SEC-MALS-SAXS at the SIBYLS beamline probes the conformational states behind electron bifurcation in the Thermotoga maritima EtfABCX, revealing insights on mechanisms at the thermodynamic limits of life. Shown are the bifurcation- and electron-conducting-like states experimentally observed for the first time in solution. Read more »
Shaping the Water-Harvesting Behavior of Metal–Organic Frameworks Aided by Fine-Tuned GPT Models
The reticular design and synthesis of metal–organic frameworks enable the structures to be engineered at an atomic level, allowing their properties to be harmoniously harnessed. AI-assisted design of building units can reduce human labor in the enumeration and search for possible structures, thereby accelerating the discovery of MOFs. Read more »
Tracking Platinum Movement on Fuel-Cell Electrodes
Researchers tracked the movement of the platinum nanoparticles that catalyze reactions in polymer electrolyte fuel cells (PEFCs) and correlated this movement with nanoparticle degradation. The results yielded solutions that can immediately reduce platinum waste in emission-free heavy-duty fuel-cell vehicles. Read more »
Computer-Aided Protein Design for New Biomaterials
Using a computer-based approach, researchers designed porous protein crystals that were revealed to be stable, tunable, and atomically accurate using x-ray scattering and diffraction at the ALS. The work provides a powerful new platform for biological materials engineering and opens up wide applications in biotechnology and medicine. Read more »
“Computer Vision” Review of X-Ray Movies Leads to New Insights
Using a type of machine learning called “computer vision” to mine data from x-ray movies, researchers made new discoveries about the reactivity of a material in rechargeable batteries. The results suggest that optimizing the carbon layer thickness on the electrode surface could help researchers to design more efficient batteries. Read more »
Building a Two-Dimensional Magnet One Atom at a Time
Researchers synthesized a new two-dimensional ferromagnet and measured how its electronic and magnetic properties evolve with increasing thickness and temperature. Such atomically thin magnetic materials with tunable magnetic properties would be very useful in next-generation microelectronic and spintronic applications. Read more »
