Impact of On-Road U.S. Vehicle Electrification and Lightweighting on Critical Materials Demand.
Environ Sci Technol
January 2025
Argonne National Laboratory, Lemont, Illinois 60439, United States.
The electrification of the transport sector is crucial for reducing greenhouse gas emissions and the reliance on fossil fuels. Battery electric vehicles (BEVs) depend on critical materials (CMs) for their batteries and electronic components, yet their widespread adoption may face constraints due to the limited availability of CMs. This study assesses the implications of vehicle electrification and lightweighting (material substitution) on the U.

Due to incessant contamination of the groundwater system near the dumpsite in southwestern Nigeria Basement Complex, this study seeks to evaluate the impact of the Odogbo dumpsite on the local groundwater system by integrating geophysical and geochemical methodologies. Aeromagnetic data covering the study area was acquired, processed, and enhanced to delineate basement features that could potentially be passing plumes to the groundwater system. Concurrently, geoelectric methods using 2-D dipole-dipole imaging and vertical electrical sounding (VES) were utilized to characterize the vulnerability indices of the lithologies underlying the dumpsite.

School of Metallurgy and Environment, Central South University, Changsha, China.
The synergistic application of calcium (Ca) and magnesium (Mg) was investigated to mitigate cadmium (Cd) uptake and translocation in rice grown in Cd-contaminated soil. A pot experiment was conducted using different Ca:Mg molar ratios (Ca1:Mg2, Ca2:Mg1, and Ca1:Mg1) to evaluate their effect on Cd uptake. The results showed that the Ca1:Mg1 treatment achieved the highest reduction in grain Cd content (54.

Background: Because arsenate (As(V)) is a highly toxic pollutant, timely on-site monitoring of its concentration is crucial for mitigating potential environmental and health hazards. Traditional on-site detection methods for As(V) often face limitations of long response time and low sensitivity. Nanozymes are nanomaterials that exhibit enzyme-like catalytic activity.

Department of Physical and Analytical Chemistry, Faculty of Chemistry, University of Oviedo. C/ Julián Clavería 8, 33006, Oviedo, Spain; Health Research Institute of Asturias (ISPA), Avda de Roma s/n, 33011, Oviedo, Spain. Electronic address:
Background: 3D cellular structures have been considered the following step in the evaluation of drugs penetration after 2D cultures since they are more physiologically representative in cancer cell biology. Here the penetration capabilities of Pt (IV)-loaded ultrasmall iron oxide nanoparticles in 143B osteosarcoma multicellular spheroids of different sizes is conducted by a multidimensional quantitative approach. Single cell (SC) and imaging techniques (laser ablation, LA) coupled to inductively coupled plasma-mass spectrometry (ICP-MS) are used to visualize their penetration pathways and distribution in comparison to those of cisplatin.
