Perovskite oxide catalysts with reduced Co content, substituted by Fe and Ni, are synthesized and studied for their activity in the oxygen evolution reaction in alkaline media. An increase in the intrinsic catalytic activity (obtained by the (RctCdl)−1 product) of the base material (Ba0.5Gd0.8La0.7Co2O6‐δ) is seen for an as high as 70 % substitution of

The rock failure mode is significantly influenced by the contributing factors, such as the joint inclination, the initial confining pressure, and the unloading point. We found six typical rock failure modes after a large number of numerical tests. Abstract Excavation unloading damages rock masses, with preferential failure along geological defects in ...

The tensile strength of granite, a proposed host for nuclear waste, degrades severely above 400°C. We link this to specific microcracking patterns captured by acoustic emission, establishing a scientific basis for assessing repository safety under thermal load.

Carbon emission assessment of tunnel infrastructures: From construction to operation
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...
