High-resolution cryo-electron microscopy makes it possible to study complex enzymatic processes in detail. With this method, a research team of the University of Potsdam and Humboldt-Universität Berlin succeeded in characterizing the CODH/ACS enzyme complex in detail. They discovered that the complex moves in the course of chemical reactions and thus determines the reaction sequence. Their results have been published in the journal Nature Catalysis.

SAN ANTONIO — July 14, 2025 — Southwest Research Institute (SwRI) is taking on the challenges of a hydrogen-powered future. In collaboration with NYSEARCH, a nonprofit research and development organization for the gas industry serving utility members across North America, SwRI is investigating how blending hydrogen into liquid natural gas (LNG) could affect the integrity of the LNG storage tanks.

Microwave-assisted catalytic reactions are considered energy-efficient and have attracted attention in various chemical processes. This is due to the selective and rapid heating of target materials or species, which is especially beneficial for highly endothermic reactions such as Dry Reforming of Methane (DRM)—a promising reaction for utilising methane and carbon dioxide. At present, reaction mechanisms and kinetic advantages under microwave irradiation remain limited. In this study, we applied Steady-State Isotopic Transient Kinetic Analysis (SSITKA) to elucidate the advantages of microwave heating. We successfully revealed that the microwave activation induces the formation of reactive coke, enhancing the rate of DRM. This work was published in the journal Industrial Chemistry & Materials on Jun 12.

Magnetic micropillar arrays, made from magnetic composite materials, can change their shape under a magnetic field. However, conventional micropillar arrays can only retain their shape temporarily when the magnetic field is active. In a recent study, researchers developed novel disulfide-based covalent adaptable networks (DS-CANs), which allow shape fixation through exposure to ultraviolet light at room temperature or upon heating. The DS-CAN-based magnetic micropillar arrays, therefore, support reversible, on-demand, and contactless shape reconfiguration.

Volatile air pollutants such as nitrogen dioxide and ozone are only monitored loosely in the EU. Separate devices are used for each individual pollutant, and real-time monitoring is not possible. Birgitta Schultze-Bernhardt from the Institute of Experimental Physics at Graz University of Technology (TU Graz) would like to simplify and significantly improve these measurements. In her MULTI TRACE research project, she is developing a portable device that can determine the concentration of several gaseous pollutants in ambient air with the utmost accuracy within fractions of a second. The heart of the system is a laser-based dual-comb spectrometer, which Birgitta Schultze-Bernhardt developed with funding from an ERC Starting Grant in the predecessor project ELFIS. In order to take the technology closer to real-world application, the European Research Council is funding the MULTI TRACE project for 18 months with a Proof of Concept Grant totalling 150,000 euros.
