The carbonation of K₂CO₃ to KHCO₃ is an interesting CO₂ capture process due to its low material cost, high selectivity, and substantial CO₂ capacity. In this study, KHCO₃ particles were packed in a dielectric barrier discharge reactor and exposed to plasma. It was found that the decomposition of KHCO₃ is mainly driven by a thermal mechanism. The energy consumption is more than one order of magnitude higher compared to the thermal approach. However, production of CO and H₂ was achieved, with the best CO₂ conversion of 9.0% ± 0.2% and energy efficiency of 3.0% ± 0.1% at a syngas ratio of 0.35 ± 0.01.

Researchers at the University of Missouri have discovered certain proteins may be the key to saving plants’ lives when multiple stressors hit at the same time. This knowledge may one day lead to crops that are more resistant to harsh conditions brought on by multiple stressors during the same growing seasons.

In a recent study, Mizzou scientists found that Arabidopsis thaliana, a plant that serves as a popular model organism for biology research, needs a specific protein to protect itself when exposed to simultaneous stress from excessive heat, sunlight and salty soil. The findings pave the way for scientists to better understand the underlying cellular biology that allows plants to survive even when hit by multiple stressors.

A study led by William & Mary's Batten School & VIMS scientists revealed that microbial communities growing on microplastics in the Chesapeake Bay carry the genetic potential to remove nitrogen from the water and break down petroleum-related compounds. The study was selected by FEMS Microbiology Ecology as best paper of 2025.

A research team from the Swire Institute of Marine Science (SWIMS) and the School of Biological Sciences of The University of Hong Kong (HKU) has helped address this question by developing an innovative mathematical model that allows conservationists to easily assess feeding strategies of different giant clam species. This knowledge can help conservationists to predict the future vulnerability of different giant clam species and identify those in need of timely protection. 

A research team at Chalmers University of Technology, Sweden, has developed new laser technology that could lead to tiny, cost-effective biosensors. The sensors integrate lasers and optics together on a centimeter-sized chip, which could move testing from hospitals to patients' homes. This, in turn, would free up hospital beds and reduce visits to clinics.

Diffusion barrier materials (DBMs) are critical for the stability and efficiency of thermoelectric devices. This study presents a streamlined approach for DBM screening in metal chalcogenide-based devices, substitution energy as a simplified criterion within the conventional DFT-based framework. A device comprising seven pairs of Ag₂Se/MgAgSb legs, with Ni employed as the DBM for the Ag₂Se legs, demonstrates excellent cooling performance.

Flexible electronics is profoundly leading the wave of transformation in fields such as wearable devices, health monitoring, and intelligent robots, and material innovation is undoubtedly the core driving force behind this revolution. As a new type of material prepared by compounding liquid metals (LM) with other materials, LM thin films, with their unique properties, have become an ideal candidate in the field of flexible electronics preparation, laying a solid foundation for the vigorous development of flexible electronics technology.

Compressed air energy storage (CAES) is an effective technology for mitigating the fluctuations associated with renewable energy sources. In this work, a hybrid cogeneration energy system that integrates CAES with high-temperature thermal energy storage and a supercritical CO2 Brayton cycle is proposed for enhancing the overall system performance. This proposal emphasizes system cost-effectiveness, eco-friendliness, and adaptability. Comprehensive analyses, including thermodynamic, exergoeconomic, economic, and sensitivity evaluations, are conducted to assess the viability of the system. The findings indicate that, under design conditions, the system achieves an energy storage density, a round-trip efficiency, an exergy efficiency, a unit product cost, and a dynamic payback period of 5.49 kWh/m3, 58.39%, 61.85%, 0.1421 $/kWh, and 4.81 years, respectively. The high-temperature thermal energy storage unit, intercoolers, and aftercooler show potential for optimization due to their suboptimal exergoeconomic performance. Sensitivity evaluation indicates that the operational effectiveness of the system is highly sensitive to the maximum and minimum air storage pressures, the outlet temperature of the high-temperature thermal energy storage unit, and the isentropic efficiencies of both compressors and turbines. Ultimately, the system is optimized for maximum exergy efficiency and minimum dynamic payback period. These findings demonstrate the significant potential of this system and provide valuable insights for its design and optimization.
