A three-dimensional (3D) electrode system is widely recognized as an effective technology for enhancing electrocatalytic effect. In this study, Cu-Ce modified granular activated carbon (GAC) particle electrodes were prepared using the impregnation method and applied to handle multiphase extraction wastewater. Structural and electrochemical characterization revealed that while the specific surface area of Cu-Ce/GAC decreased by 13.

Article Synopsis
- Xylene isomers, including -xylene, -xylene, -xylene, and ethyl benzene, are significant industrial raw materials, but their separation is challenging due to similar properties.
- Metal-organic frameworks (MOFs) are emerging as effective tools for separating these isomers by utilizing multiple molecular-scale mechanisms.
- The review highlights advances in MOFs for various separation techniques and concludes with potential future directions and existing challenges in the development of high-performance MOF separators.
An in situ reactive zone approach using calcium peroxide for the remediation of benzene and chlorobenzene in groundwater: A field study.

State Key Laboratory of Soil and Sustainable Agriculture, Institute of Soil Science, Chinese Academy of Sciences, Nanjing, 211135, China; University of Chinese Academy of Sciences, Beijing, 100049, China. Electronic address:
There is a gap in understanding the different contributions of biodegradation and free radical oxidation using calcium peroxide (CaO) for the remediation of mixed contaminants of benzene and chlorobenzene in groundwater. In this study, the remedial efficiency and mechanisms of benzene and chlorobenzene co-contaminants using CaO were explored by an integrated approach of field study and laboratory validation. It was found that in the field demonstration program, the radius of influence for each injection point using Geoprobe direct-push was larger than the designed value of 0.

The computational study of ligand binding to a target protein provides mechanistic insight into the molecular determinants of this process and can improve the success rate of drug design. All-atom molecular dynamics (MD) simulations can be used to evaluate the binding free energy, typically by thermodynamic integration, and to probe binding mechanisms, including the description of protein conformational dynamics. The advantages of MD come at a high computational cost, which limits its use.

Background: Despite evidence from experimental studies linking some petroleum hydrocarbons to markers of immune suppression, limited epidemiologic research exists on this topic.
Objective: The aim of this cross-sectional study was to examine associations of oil spill related chemicals (benzene, toluene, ethylbenzene, xylene, and n-hexane (BTEX-H)) and total hydrocarbons (THC) with immune-related illnesses as indicators of potential immune suppression.
Methods: Subjects comprised 8601 Deepwater Horizon (DWH) oil spill clean-up and response workers who participated in a home visit (1-3 years after the DWH spill) in the Gulf Long-term Follow-up (GuLF) Study.
