Risk assessment using IEUBK model for the Naica mine tailings

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract Mexico has a long history of mineral extraction, during which limited environmental regulations allowed the accumulation of toxic waste near communities, primarily in rural or undeveloped areas. Some of these toxic substances, such as lead, pose significant risks to vulnerable populations, particularly children aged 0 to 7 years.

Impact of toroidal magnetic field direction on integrated ELM-stable operation and divertor power exhaust via boron powder injection in EAST

open access: yesNuclear Fusion
We report the first in-depth comparison of the impact of toroidal magnetic field direction on solid boron injection used for Edge-Localized Mode (ELM) control, power exhaust, and core high- Z impurity control in the Experimental Advanced Superconducting ...

Waste to Hydrogen: Transforming Food Waste Into Biohythane (Bio‐H2 + Bio‐CH4) in a Two‐Stage Reactor With the Aid of a Metal‐Ion Catalyst

open access: yesEnergy Science &Engineering, EarlyView.
This study demonstrates a two‐stage catalytic bioreactor system that converts real food waste into high‐purity biohydrogen and biohythane. In Stage‐1, an enriched Clostridium thermocellum culture combined with Ni2+─Fe2+ bimetallic catalysis enhances hydrolysis efficiency and hydrogenase activity, resulting in a 77% increase in H2 yield and 75.8% purity

Multifunctional Properties of Wintergreen (Gaultheria procumbens) Essential Oil: Antimicrobial, Antibiofilm, and Insecticidal Effects

open access: yesFlavour and Fragrance Journal, EarlyView.
Unveiling the potential of Wintergreen (Gaultheria procumbens) essential oil. ABSTRACT This study investigated the antimicrobial, antibiofilm, and insecticidal properties of wintergreen (Gaultheria procumbens L.) essential oil (GPEO). The EO was chemically characterized by GC–MS, confirming methyl salicylate as the predominant compound (99.3%).

Access to an ELM-suppressed X-point radiator regime in TCV snowflake minus configurations

open access: yesNuclear Materials and Energy
TCV’s operating regime with an X-point radiator (XPR) has been broadened by changing the magnetic geometry. XPRs have properties that could make them an attractive power exhaust solution for fusion reactors. These include the conversion of a high fraction of exhaust power into radiation. TCV had previously accessed the XPR regime only with difficulties,

Synthesis and Characterization of Juglone‐Derived cu (II), Mn (II) and Zn (II) Complexes and Investigation of Their Cytotoxic Activities Against Lung and Colon Cancer Cells in Vitro and in Silico

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Three new Zn (II), Cu (II) and Mn (II) complexes have been synthesized from 5‐hydroxy‐1,4‐naphthoquinone (HNQ). Elemental analysis, magnetic susceptibility, UV–Vis, IR and Mass spectrometry have all been used to explore the structural characterization of these compounds.

New Hydrazone Derivatives Featuring Isatin and Piperazine Moieties: Synthesis, Cytotoxicity Evaluation, and Molecular Modeling Studies

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT In this study, ten novel compounds (IPH1–IPH10) were designed by integrating three pharmacophores (isatin, piperazine, and hydrazone) commonly found in the molecular structures of anticancer agents. The target molecules were obtained by the reaction of in‐house prepared 4‐(4‐(pyridin/pyrimidin‐2‐yl)piperazin‐1‐yl)benzohydrazide with various ...
