The adoption of carbon capture, utilization, and storage (CCUS) technology is increasingly prevalent, driven by the global initiative to conserve energy and reduce emissions. Nevertheless, CCUS has the potential to induce corrosion in equipment, particularly in high-pressure environments containing carbon dioxide (CO). Therefore, anti-corrosion protection is necessary for the metal utilized for CO production and storage equipment.

In recent years, metal hydride research has become one of the driving forces of the high-pressure community, as it is believed to hold the key to superconductivity close to ambient temperature. While numerous novel metal hydride compounds have been reported and extensively investigated for their superconducting properties, little attention has been focused on the atomic and electronic states of hydrogen, the main ingredient in these novel compounds. Here, we present combined H- and La-NMR data on lanthanum superhydrides, LaH, (x = 10.

Oxygen vacancies (OVs) spatially confined on the surface of metal oxide semiconductors are advantageous for photocatalysis, in particular, for O-involved redox reactions. However, the thermal annealing process used to generate surface OVs often results in undesired bulk OVs within the metal oxides. Herein, a high pressure-assisted thermal annealing strategy has been developed for selectively confining desirable amounts of OVs on the surface of metal oxides, such as tungsten oxide (WO).

Recent studies have emphasized the modification of Insoluble Dietary Fiber (IDF) to enhance its physicochemical properties and functional performance. This study systematically examined the effects of ultrasonic treatment, microwave irradiation, high-temperature and high-pressure processing, and screw extrusion on the physicochemical characteristics, in vitro antioxidant activity, and adsorption capacities of High-Purity Insoluble Dietary Fiber (HPIDF) derived from black bean residues. Although these physical modifications did not alter the functional group composition or crystalline structure of HPIDF, they significantly enhanced its porosity, water-holding capacity (WHC), oil-holding capacity (OHC), and adsorption capacities for glucose, cholesterol, bile salts, and metal ions.
