Surface modification of semiconductor photoelectrodes

Kevin Sivula, Nestor Guijarro Carratala, Mathieu Steven Prévot

Photoelectrochemical (PEC) cells have emerged as promising devices that afford the direct conversion of solar energy into electric power and/or chemical fuels. Apart from the obvious importance of the bulk properties of semiconductor materials employed as ...

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 ...

Coupled Approach to Assess Caprock Deformation Caused by CO2 Injection

Lyesse Laloui, Chao Li

This study focuses on a specific problem related to the caprock deformation induced by the injection of CO2 at depth. The adopted methodology includes the development of a mathematical model that incorporates the deformable behaviour of storage media and t ...

Analysis and prediction of TBM performance in blocky rock conditions at the Lotschberg Base Tunnel

Jian Zhao, Andrea Delisio

This paper focuses on the analysis of the TBM performance recorded during the excavation of the Lotschberg Base Tunnel. The southern part of the tunnel was excavated by two gripper TBMs, partly through blocky rock masses at great depth. The jointed nature ...

Case studies of TBM tunneling performance in rock-soil interface mixed ground

Jian Zhao, Ákos Tóth

This paper investigates the performance of tunnel boring machines (TBMs) in rock-soil mixed-face ground based on TBM tunneling projects in Singapore. Currently several methods are available to estimate TBM tunneling performance in homogenous rock or soil. ...
