Geo-environmental and mechanical behaviors of As(V) and Cd(II) co-contaminated soils stabilized by goethite nanoparticles modified biochar

Biochar, 2023
Goethite nanoparticles modified biochar (FBC) could address the weak effectiveness of conventional biochar commonly to process heavy metal(loids)  (HMs) co-contamination with different charges.

SWCC of Calcareous Silty Sand Under Different Fines Contents and dry Densities

Frontiers in Environmental Science, 2021
Investigating the soil-water characteristics of calcareous soil has a great significance for preventing geological disasters on island-reefs as well as maintaining the foundation stability of hydraulic-filled island-reefs. In this study, calcareous silty

Accelerating Phosphate Transport Across Membranes via Synergistic Chemical‐Electrochemical Carriers

Angewandte Chemie, EarlyView.
A new membrane design principle based on synergistic chemical and electrochemical carriers is proposed to construct an electro‐driven carrier‐conducting membrane for high‐throughput phosphate transport. Monodispersed ferrihydrite nanoparticles embedded within the membrane act as built‐in phosphate carriers, enabling accelerated phosphate migration via ...

Effect of pore-size distribution on the collapse behaviour of anthropogenic sandy soil deposits

E3S Web of Conferences, 2016
In the former open-pit mines of the Lusatian region in Germany, several liquefaction events have occurred during the recent years in the anthropogenic deposits made of very loose sandy soils.

Observations from large-scale triaxial compression tests at jointed slaking rock masses [PDF]

EPJ Web of Conferences
Triaxial compression tests are commonly used to characterise strength and deformation behaviour of rock to determine parameters for engineering design and modelling. For triaxial tests, intact specimens are usually selected to determine parameters of the

Differences in the permeability assessment of the fractured reservoir rocks using the conventional and the rough discrete fracture network modeling

Journal of Petroleum Exploration and Production Technology, 2023
Permeability assessment of naturally fractured rocks and fractured rocks after fracturing is critical to the development of oil and gas resources. In this paper, based on the discrete fracture network (DFN) modeling method, the conventional discrete ...

Detection and Evaluation Technologies for Using Existing Salt Caverns to Build Energy Storage

Energies, 2022
Underground salt caverns are widely used in large-scale energy storage, such as natural gas, compressed air, oil, and hydrogen. In order to quickly build large-scale natural gas reserves, an unusual building method was established.
