Effectiveness analysis of pre-cooling methods on hydrogen liquefaction process

, 2020
The purpose of this analytic study is to design and examine an efficient hydrogen liquefaction cycle by using a pre-cooler. The liquefaction cycle is primarily comprised of a pre-cooler and a refrigerator. The fed hydrogen gas is cooled down from ambient

Cryogenic TDS Platform for Quantitative Hydrogen Isotope (H2/D2/HD) Separation via Quantum Sieving in Porous Materials

Small, EarlyView.
The AC‐TDS enables precise hydrogen isotope analysis over a wide temperature range (15–900 K), allowing both physisorption and chemisorption processes to be investigated under gas exposure conditions. Through calibration, this system achieves reliable quantitative desorption analysis, including direct quantification of H2, D2, and HD under mixed ...

Modeling the Thermal Properties of Hydrogen‐Based Direct Reduced Iron Using Computational Thermodynamics and Machine Learning

steel research international, EarlyView.
Hydrogen‐based direct reduced iron (H‐DRI) melts differently from scrap and carbon‐bearing DRI. This work combines differential scanning calorimetry experiments, FactSage thermodynamics, and simple composition‐based regression to predict solidus, liquidus, heat capacity, and enthalpy for H‐DRI.

Synthesis and Structure Solution of Ba[SeCN]2

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The new quasi‐binary selenocyanate Ba[SeCN]2 was synthesized by the reaction of barium hydroxide with ammonium selenocyanate. Its crystal structure was determined from powder X‐ray diffraction (PXRD) data. Additionally, density functional theory (DFT) analysis and Raman spectroscopy were performed.
