Electrical Resistance Tomography (ERT) for Concrete Structure Applications: A Review

Buildings
Electrical resistance tomography (ERT) is gaining recognition as an effective, affordable, and nondestructive tool for monitoring and imaging concrete structures. This paper discusses ERT’s applications, including crack detection, moisture ingress monitoring, steel reinforcement assessment, and chloride level profiling within concrete.

Influence of Contact Pressure on Performance and Crossover in Zero‐Gap Alkaline Water Electrolysis

Chemie Ingenieur Technik, EarlyView.
Cell performance and product gas quality in zero‐gap alkaline water electrolysis are influenced by the mechanical contact pressure in the electrode area. With a newly developed contact‐pressure cell, it was found that the influence of contact pressure can vary drastically, depending on the cell configuration, electrode type, and diaphragm.

Exponentially‐constrained Gaussian mixture model for quantifying vertical development of water‐conducting fracture zones in lithologically stratified mining roofs

Deep Underground Science and Engineering, EarlyView.
This study proposes an exponentially‐constrained Gaussian mixture model (EcGMM) to quantify vertical fracture heterogeneity in stratified roof strata. The model integrates a piecewise exponential decay term capturing global stress dissipation with Gaussian components representing localized fracture intensification at lithological interfaces.
