New research from the Stratospheric Observatory for Infrared Astronomy (SOFIA) has shown that the magnetic fields in 30 Doradus — a region of ionized hydrogen......

Coal gasification is recognized as the core technology of clean coal utilization that exhibits significant advantages in hydrogen-rich syngas production and CO2 emission reduction. This review briefly discusses the recent research progress on various coal gasification techniques, including conventional coal gasification (fixed bed, fluidized bed, and entrained bed gasification) and...

Technology demonstrations show the machine’s major components achieve the required performance....

Human lactate dehydrogenase (hLDH) is a tetrameric enzyme present in almost all tissues. Among its five different isoforms, hLDHA and hLDHB are the predominant ones. In the last few years, hLDHA has emerged as a therapeutic target for the treatment of several kinds of disorders, including cancer and primary hyperoxaluria....

This study designed an externally pressurized bearing and analyzed the rotordynamics of a turbo expander for a hydrogen liquefaction plant. The turbo expander, comprising a turbine and compressor wheel assembled to a shaft, lowered the temperature of the helium refrigerant. Its rated speed was 75,000 rpm, and an externally pressurized...

This 3D rendering illustrates two monomers forming a reversible double-hydrogen bond that slows down polymer movement without creating an elastic network. Image: S. Nian et al., Phys. Rev. Lett. 130, 228101 (2023).A study led by researchers at the University of Virginia (UVA) into a class of materials called associative polymers...

The use of energy-saving materials is an effective strategy for decreasing energy consumption and carbon emission. Wood is a type of biomass material with a natural hierarchical structure, which results in its high thermal insulation. It has been widely used in construction. However, developing wood-based materials without flammability and dimensional...

A novel manganese dioxide–hydrogen peroxide (MnO2–H2O2) system was developed for effective Arsenic (As) removal. Under the specified conditions of no external mechanical stirring, a trace H2O2 concentration of 0.015 wt%, and a MnO2 concentration of 25 mg/L, high removal efficiency (88%) of As (100 µg/L) was achieved by the MnO2–H2O2...

Protium explores green hydrogen production in a case study of the Protium Project Pioneer 1, exploring carbon storage and net zero possibilities in energy. The post Hydrogen production in the energy transition: Exploring Protium Project Pioneer 1 appeared first on Open Access Government....
