Environmental Implications of the Soil-to-Groundwater Migration of . . . Groundwater contamination was studied at several hotspot sites in the Majdanpek copper mining area (Serbia) These sites include a milling facility, a metallurgical wastewater treatment plant, a heavy vehicle service area, and a waste disposal site In addition to Cu, high concentrations of As and heavy metals (Cd and Pb) were detected in groundwater and soil at the same sampling points
Solidification and Casting of Metals and Alloys - MDPI Accordingly, this Special Issue of Metals, entitled “Solidification and Casting of Metals and Alloys”, will review the latest developments in the various aspects of solidification metallurgy Specifically, we will cover the following: (a) metallurgical control of the composition and microstructure of metals or castings; (b) micro- and macrosegregation mechanisms, as well as the
Effects of Surface Treatment on Adhesive Performance of Composite-to . . . This study deals with the long-running challenge of joining similar and dissimilar materials using composite-to-composite and composite-to-metal joints This research was conducted to evaluate the effects of surface morphology and surface treatments on the mechanical performance of adhesively bonded joints used for the aircraft industry A two-segment, commercially available, toughened epoxy
Bioaccumulation and Trophic Transfer of Heavy Metals in Marine Fish . . . Heavy metal contamination in marine ecosystems poses a critical environmental challenge, with significant implications for biodiversity, trophic dynamics, and human health Marine fish are key bioindicators of heavy metal pollution because of their role in food webs and their capacity for bioaccumulation and trophic transfer This review synthesizes current knowledge on the pathways and
Characterization, Source Analysis, and Ecological Risk . . . - MDPI Most risk assessment and source apportionment studies of the heavy metals in the surface soils in China have focused primarily on East China, whereas studies focused on Northwest China, particularly regarding heavy metals in surface soils in the central and western areas, remain limited In this study, surface soils in the central–western Ali region were investigated, and the concentrations
Aims Scope | Metals | MDPI Aims Metals (ISSN 2075-4701) is an open access journal of related scientific research and technology development It publishes reviews, regular research papers (articles) and short communications Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible Therefore, there is no restriction on the maximum length of the papers The
Immobilization of Heavy Metals in Biochar Derived from Biosolids . . . Slow pyrolysis was carried out in biosolids under three different temperatures (400, 500 and 600 °C) and two different carrier gases (CO2 and N2) on a fluidized bed reactor The total concentration, chemical fractionation, and plant availability of the heavy metals in biochar were assessed by standard methods The total concentration of Fe, Zn, Cu, Mn, Cr, Ni and Pb increased with the
Simulation and Experimental Comparison of Laser Impact Welding with a . . . In this study, spatial and temporal profiles of an Nd-YAG laser beam pressure pulse are experimentally characterized and fully captured for use in numerical simulations of laser impact welding (LIW) Both axisymmetric, Arbitrary Lagrangian-Eulerian (ALE) and Eulerian dynamic explicit numerical simulations of the collision and deformation of the flyer and target foils are created The effect of
Synthesis and Characterization of Highly Fluorinated Hydrophobic Rare . . . Tuning a material’s hydrophobicity is desirable in several industrial applications, such as hydrocarbon storage, separation, selective CO 2 capture, oil spill cleanup, and water purification The introduction of fluorine into rare-earth (RE) metal–organic frameworks (MOFs) can make them hydrophobic In this work, the linker bis (trifluoromethyl)terephthalic acid (TTA) was used to make
