Abstract The thermal conductivity of nanofluids is an important property that influences the heat transfer capabilities of nanofluids. Researchers rely on experimental investigations to explore nanofluid properties, as it is a necessary step before their practical application. As these investigations are time and resource-consuming undertakings, an effective prediction model can significantly improve the efficiency of research operations. In this work, an Artificial Neural Network (ANN) model is developed to predict the thermal conductivity of metal oxide water-based nanofluid. For this, a comprehensive set of 691 data points was collected from the literature. This dataset is split More >

Abstract Accurately predicting fatigue life under multiaxial fatigue damage conditions is essential for ensuring the safety of critical components in service. However, due to the complexity of fatigue failure mechanisms, achieving accurate multiaxial fatigue life predictions remains challenging. Traditional multiaxial fatigue prediction models are often limited by specific material properties and loading conditions, making it difficult to maintain reliable life prediction results beyond these constraints. This paper presents a study on the impact of seven key feature quantities on multiaxial fatigue life, using Convolutional Neural Networks (CNN), Long Short-Term Memory Networks (LSTM), and Fully Connected Neural… More >

Abstract The development of quick, accurate, and field-deployable detection techniques is required due to the growing environmental pollution caused by heavy metals, especially lead (Pb) and cadmium (Cd). In this work, bismuth silver sulfide (AgBiS₂) nanoparticles are synthesized using a simple hydrothermal method aided by biomolecules, and they are used as a new modifier forPb(II) and Cd(II) simultaneous electrochemical detection using screen-printed electrodes (SPEs). After thorough material characterisation, pure, highly crystalline, quasi-spherical AgBiS₂ nanoparticles produced with an average diameter of around 20 nm. The AgBiS₂/SPE sensor demonstrated a threefold decrease in charge transfer resistance, indicating a considerable improvement More >

Abstract Heavy metal accumulation in agricultural soil is primarily driven by pesticides, polluted water, and industrial gas emissions, which pose threats to sustainable crop production. Chromium (Cr) stress has an adverse impact on plant development and metabolism, but approaches to reduce its toxicity and enhance plant resistance remain limited. Melatonin is a potent antioxidant involved in regulating various morpho-physiological functions of plants under different abiotic stresses. In this study, we investigated the impact of exogenous melatonin to mitigate the negative effects of potassium dichromate (PD) stress in melon plants and analyzed genetic modulation of morphological, physiological,… More >

Abstract The use of organic fertilizers can be an opportunity to increase crop yield and improve soil fertility in semi-arid regions, since soils from these regions usually have unfavourable conditions for plant growth. This research investigates the effects of organic and mineral fertilization on the impact of soil properties (pH, electrical conductivity and organic matter), availability of macro- (N, P and K), micro-nutrients (Fe, Mn, Cu and Zn) and the accumulation of heavy metals (Pb, Cd, Cr) in soil and potato tubers grown under semiarid conditions. A field experiment was conducted in Raqqa Governorate (Syria) using… More >

Abstract Heavy metal contamination in water sources is a widespread global concern, particularly in developing nations, with various treatment approaches under extensive scientific investigation. In the present study, we fabricated electrospun composite polyvinylidene fluoride (PVDF) nanofibrous membranes exhibiting hierarchical surface roughness and superhydrophobicity for the removal of heavy metal ions via vacuum membrane distillation (VMD) process. The membranes were prepared by incorporating optimized dosing of silica nanoparticles, followed by a two-step membrane modification approach. These membranes exhibited notable characteristics, including elevated water contact angle (152.8 ± 3.2°), increased liquid entry pressure (127 ± 6 kPa), and… More > Graphic Abstract

Abstract Activated charcoals were synthesized from sugar palm bunches (SPB) of the native tree of Arenga longipes in Indonesia. The synthesized activated charcoal (AC) was characterized, and utilized as an absorbent for heavy metals (lead/Pb and copper/Cu) through thermal activation. The synthesis of AC was accomplished through furnace activation at temperatures of 500°C, 600°C, 700°C, and 800°C. Acid chlorides were blended with the SPB-AC samples at 5% impregnation level and subsequently subjected to washing for activation, resulting in the elimination of volatile substances and ash content, which facilitates the development of a porous structure in the activated… More >

Abstract Present research reveals the doping effect on physical properties of Sr_1-xFe_xS by employing ab-initio calculations. The negative formation energy and optimization outcomes exhibit the stability of the Sr_1-xFe_xS alloys with ferromagnetic phase. Spin dependent band structure (BS) and density of states (DOS) interpret that Sr_1-xFe_xS revealed half metallic ferromagnetic (HMF) nature at 6.25% and 12.5% of Fe doping while metallic character is revealed at 25% concentration of dopant. Spin-up state of Sr_0.9375Fe_0.0625S and Sr_0.8750Fe_0.1250S depicts semiconductive behavior with bandgap value of 2.01/2.33 eV, correspondingly, while metallic in spin-down channel.

Abstract This research introduces an innovative aptasensor for detecting alpha-fetoprotein with exceptional sensitivity and specificity, employing a novel MoS₂/Fe₃O₄ composite fabricated through an advanced in-situ growth methodology. The composite exhibited a hierarchical flower-like structure with uniformly distributed Fe3O4 nanoparticles, confirmed by SEM, XRD, and Raman spectroscopy. The MoS₂/Fe₃O₄ composite demonstrated a 66% increase in surface area (7.16 m^²/g) compared to pristine MoS2, enhancing aptamer immobilization and electron transfer efficiency. Electrochemical characterization revealed a significant increase in interfacial resistance upon AFP binding, with a detection limit of 0.3 pg/mL and a dual linear range of 0.001–0.1 ng/mL and 0.1–100 More >

Abstract The remediation of acid mine drainage (AMD), characterized by its high concentrations of toxic metal ions and low pH, presents a significant environmental challenge. In this study, exfoliated two-dimensional MoS_₂ nanosheets were prepared using a liquid-phase ultrasonication method and evaluated for their efficiency in removing Cd^²⁺, Cu^²⁺, and Pb^²⁺ from aqueous solutions. Detailed structural and morphological analyses confirmed that the exfoliation process significantly enhanced surface area, pore volume, and exposure of reactive sulfur sites. Through isotherm and kinetic modeling analyses, the adsorption behavior was found to align with the Langmuir model and pseudo-second-order kinetic equation, which implies More >
