Large Orbital Moment of Two Coupled Spin-Half Co Ions in a Complex on Gold

The magnetic propertiesof transition-metal ions aregenerallydescribed by the atomic spins of the ions and their exchange coupling.The orbital moment, usually largely quenched due the ligand field,is then seen as a perturbation. In such a scheme, S = 1/2 io ...

Nuclear receptor corepressor 1 represses cardiac hypertrophy

Johan Auwerx, Xu Liu, Chao Li, Jun Wang, Yan Liu, Yuan Liu, Shuai Shao

The function of nuclear receptor corepressor 1 (NCoR1) in cardiomyocytes is unclear, and its physiological and pathological implications are unknown. Here, we found that cardiomyocyte-specific NCoR1 knockout (CMNKO) mice manifested cardiac hypertrophy at b ...

Coupled Thermo-hydro-Mechanical Effects on Caprock Stability During Carbon Dioxide Injection

Lyesse Laloui, Chao Li

This study presents a numerical investigation of the effects of coupled material properties on the caprock stability. A thermo-hydro-mechanical framework is proposed in order to reproduce the physical processes. The results indicate that for a given geomet ...

Impact of material properties on caprock stability in CO2 geological storage

Lyesse Laloui, Chao Li

In this study, thermo-hydro-mechanical coupled simulations are performed to investigate caprock stability under cooling and pressurization during the injection of carbon dioxide. It is shown that failure potential of caprock increases with a higher value o ...

Coupled multiphase thermo-hydro-mechanical analysis of supercritical CO2 injection: benchmark for the In Salah surface uplift problem

Lyesse Laloui, Chao Li

CO2 storage in deep aquifers, which is considered one of the most viable technologies, is delivering on its promise of limiting the greenhouse effect. Nevertheless, deep aquifers may experience significant deformation and geomechanical instabilities, such ...

Geomechanical modelling of CO₂ injection in deep aquifers

Chao Li

CO2 sequestration in deep geological formations is considered as a promising technology to reduce the impact of CO2 on the greenhouse effect. Practically, large-volume of CO2 could be injected into a system that consists of a highly porous host reservoir c ...

Hydro-mechanical analysis of volcanic ash slopes during rainfall

Lyesse Laloui, John Eichenberger, Alessio Ferrari, Chao Li

Rainfall-induced landslides in volcanic ashes represent a major natural hazard in many regions around the world. Due to their loose structure, volcanic ash slopes are prone to rainfall-induced landslides. The paper presents a continuum modelling approach f ...

A hydromechanical approach to assess CO2 injection-induced surface uplift and caprock deflection

Lyesse Laloui, Chao Li

This study focuses on the derivation of a semi-analytical approach for the evaluation of surface uplift and caprock deflection induced by underground injection of CO2. The adopted methodology includes the development of a mathematical model that incorporat ...

Heat-exchanger piles for the de-icing of bridges

Lyesse Laloui, Fabrice Dupray, Chao Li

Of the various types of road structures, bridges are the most exposed to icing; the problem of icing is widely addressed through salting, which reduces the lifespan of the bridge. One promising solution to avoid the use of salt is the seasonal storage of s ...

THM coupling sensitivity analysis in geological nuclear waste storage

Lyesse Laloui, Fabrice Dupray, Chao Li

A deep geological repository involving a multi-barrier system constitutes one of the most promising options to isolate high-level radioactive waste from the human environment. In order to certify the efficiency of waste isolation, it is essential to unders ...
