Abstract:
We report the new structures of aluminum hydrides derived from the Al4 tetrahedral cages. We perform ab initio quantum chemical calculation for these new aluminum hydrides. Our calculation of binding energies of the new aluminum hydrides reveal that stability of these hydrides increases as more hydrogen atoms are adsorbed, while stability of Al-H bonds decreases. We also calculate electronic stress tensor to evaluate the chemical bonds of these hydrides. As a result, we find that the bonds of the Al4 tetrahedral cage are strengthened as more hydrogen atoms are adsorbed on the aluminum hydrides

The widespread implementation of the hydrogen economy demands access to materials with a high weight percentage of hydrogen. Mg-based hydrogen storage alloys have become a research hot-spot in recent years owing to their high hydrogen storage capacity, good reversibility of hydrogen absorption/desorption, low cost, and abundant resources. However, high decomposition temperature of Mg-based hydrides limits their practical usage.

Abstract:
ABSTRACT Temperature fluctuations within a wellbore are common occurrences in various applications, including carbon sequestration, hydrogen storage, and thermal storage. To ensure long-term well integrity, it is necessary to investigate the mechanical response of the cement annulus under thermal loading. In this study, we designed a two-layer cement casing structure to evaluate the stress state at the cement-casing interface under high pressure and high temperature conditions. We cured Class-G cement with a water-cement ratio of 0.4 and poured it inside the casing, subjecting it to 40 MPa and

Abstract:
A new type of apparatus for material testing in high-pressure gas of up to 100 MPa was developed. The apparatus consists of a pressure vessel and a high-pressure control system that applies the controlled pressure to the pressure vessel. A piston is installed inside a cylinder in the pressure vessel, and a specimen is connected to the lower part of the piston. The load is caused by the pressure difference between the upper room and the lower room separated by the piston, which can be controlled to a loading mode by the pressure valves of the high-pressure system supplying gas to the vessel.
