Background: Human exposure to cadmium has various effects on health, especially on male reproductive organs. Although it is widely known that prenatal maternal cadmium exposure can affect birth outcomes, the effect of paternal exposure to cadmium remains unclear. Objectives: This study aimed to evaluate the effect of paternal cadmium exposure on fetal growth by considering maternal cadmium exposure and exposure to other heavy metals, namely mercury and lead. Methods: The Mothers and Children's environmental Health (MOCEH) study is a prospective birth cohort study in Korea. Overall, 1313 families (father-mother-child triple) without child abnormalities and who completed paternal whole blood cadmium assessments were included in this study. Families were divided into two subgroups based on the blood sampling periods, namely early and late pregnancy. Subjects were selected as follows: one family triple with a high level of paternal cadmium and two triples with low levels of paternal cadmium, using the method of propensity score matching. And linear regression analyses were performed. Results: The group with high paternal cadmium exposure (80% or more;1.93 μg/L) had lower birth weight infants compared to the group with low cadmium concentrations (β(se) = −0.21(0.10);p-value = 0.0283). After stratification by infant sex, prenatal paternal cadmium exposure significantly reduced the birth weight of females in subgroups of different sampling times, namely early pregnancy (β(se) = −0.52 (0.22);p-value = 0.0170) and late pregnancy (β(se) = −0.43 (0.18);p-value = 0.0160). Finally, after performing propensity score matching in the early pregnancy measurement group, it was found that the prenatal exposure of father to cadmium significantly reduced birth weight in females (β(se) = −0.72(0.25);p-value = 0.0047). Conclusion: This study assessed the effect of paternal cadmium exposure on birth outcomes in family units consisting of a father, mother, and child. Prenatal paternal cadmi

This study presents an investigation of chemical and physical characterization, green process analysis, techno-economic considerations, and carbon emissions for synthesizing metal-organic frameworks (MOFs) from plastic and can waste using microwave-assisted synthesis. The microwave-assisted synthesis proves to be more cost-effective, with a reduction in CO₂ emissions by up to 80%. The synthesized material (MIL-Mw-U) demonstrates excellent performance in methylene blue (MB) removal, achieving 98.41% removal, with 97.87% removal although the catalyst is used in the third cycle. The adsorption of methylene blue (MB) onto MIL-Mw-U achieved a maximum capacity of 295.26 mgg⁻¹ at pH 3 and decreased to 258.68 mgg⁻¹ at pH 11 due to OH⁻ competition. The Langmuir isotherm (R² = 0.9381) and pseudo-second-order kinetics (R² = 0.999) confirmed monolayer chemisorption as the dominant mechanism. This innovative approach supports circular economy principles by converting can and plastic bottle waste into functional material for dye removal, offering sustainable solutions for environmental challenges. © 2025 The Authors

Domoic acid (DA) is a naturally produced neurotoxin synthesized by marine diatoms in the genus Pseudo-nitzschia. DA accumulates in filter-feeders such as shellfish, and can cause severe neurotoxicity when contaminated seafood is ingested, resulting in Amnesic Shellfish Poisoning (ASP) in humans. Overt clinical signs of neurotoxicity include seizures and disorientation. ASP is a significant public health concern, and though seafood regulations have effectively minimized the human risk of severe acute DA poisoning, the effects of exposure at asymptomatic levels are poorly understood. The objective of this study was to determine the effects of exposure to symptomatic and asymptomatic doses of DA on gene expression patterns in the zebrafish brain. We exposed adult zebrafish to either a symptomatic (1.1 ± 0.2 μg DA/g fish) or an asymptomatic (0.31 ± 0.03 µg DA/g fish) dose of DA by intracelomic injection and sampled at 24, 48 and 168 h post-injection. Transcriptional profiling was done using Agilent and Affymetrix microarrays. Our analysis revealed distinct, non-overlapping changes in gene expression between the two doses. We found that the majority of transcriptional changes were observed at 24 h post-injection with both doses. Interestingly, asymptomatic exposure produced more persistent transcriptional effects - in response to symptomatic dose exposure, we observed only one differentially expressed gene one week after exposure, compared to 26 in the asymptomatic dose at the same time (FDR <0.05). GO term analysis revealed that symptomatic DA exposure affected genes associated with peptidyl proline modification and retinoic acid metabolism. Asymptomatic exposure caused differential expression of genes that were associated with GO terms including circadian rhythms and visual system, and also the neuroactive ligand-receptor signaling KEGG pathway. Overall, these results suggest that transcriptional responses are specific to the DA dose and that asymptomatic exposure can

Discovery of electrocatalysts composed of cheap transition metals are in urgent to replace the traditional Pt/C catalyst used for oxygen reduction reaction (ORR). Herein, we synthesized Cu nanoparticles encapsulated with nitrogen-doped carbon (Cu@NC) as an excellent and durable catalyst for ORR. A systematic evaluation of effect of Cu content, acid leaching and secondary heat treatment have been established with the help of half-cell studies. The morphological analysis revealed that Cu nanoparticles surrounded by a thick nitrogen doped carbon layers and further, the acid leaching and subsequent pyrolysis, boosted the electrocatalytic performance. The optimized Cu@NC catalyst showed onset potential and half-wave potential of 0.975 V vs. RHE (potential corresponding to a current density of 0.1 mA cm-2) and 0.85 V vs. RHE, surpassing Pt/C catalyst. In addition, the Cu@NC catalyst exhibited outstanding durability, tolerance to carbon monoxide and methanol molecules. In the alkaline fuel cell, Cu@NC catalyst delivered 118 mW cm-2 peak power density in alkaline fuel cell operated with H2-O2, whereas Pt/C only delivered a peak power density of 97 mW cm-2 under ambient operating conditions. High ORR activity and better stability of Cu@NC catalyst could be a potential alternative to Pt/C catalyst in alkaline fuel cells and metal-air cell cathodes. © 2022, The Authors.

Rational design of oxygen reduction reaction (ORR) electrocatalysts with indestructible active sites for high-performance Zn-air batteries (ZABs) remains a significant challenge. Herein, we achieve an innovative active site design by encaging Co nanoparticles within the Co−N4 atomic sites-dispersed graphite nanopocket (CoSAs-NPs/NC), leading to outstanding alkaline ORR activity and stability, and consequently ultra-high power density of 193.8 mW cm–2 and specific capacity of 819.1 mAh gZn–1 at 10 mA cm–2 of a primary ZAB assembled, along with impressive power density of 73.4 mW cm–2 and charging/discharging stability up to 110 cycles of a flexible solid-state ZAB. Theoretical calculations unveil the enhanced ORR kinetics can be traced to the significantly optimized local electronic structure of Co−N4 sites with upshifted d-band center and reduced energy barrier of rate-limiting step by the encaged Co nanoparticle. This study showcases a creative conformational design for guiding the construction of valid synergy in hybridized metal/single-atom catalysts. © 2023, The Authors. All rights reserved.

Fractional free volume (FFV) characterizes the microstructural level features of polymers and affects their properties including thermal, mechanical, and separation performance. Experimental measurements and theoretical analyses have been used to quantify the FFV of polymers, but challenges remain because of their limitations. Experimental measurements are laborious and based on semi-empirical equations, while Bondi’s group contribution theory involves ambiguities like the determination of van der Waals volume and the choice of factor values in the theoretical equation. To efficiently evaluate the FFV of polymers, this study utilizes high-throughput molecular dynamics (MD) simulations to build a large dataset regarding polymer’s FFV. Based on this large dataset, we further build machine learning (ML) models to establish the composition-structure relation. Inspired by group contribution theory which correlates polymer’s functional groups to FFV, our ML models correlate polymer’s sub-structures or physico-chemical indexes to FFV. Our study first benchmarks the MD simulation protocol to obtain reliable FFV of polymers and then carries out high-throughput MD simulations for more than 6,500 homopolymers and 1,400 polyamides. Such a large and diverse dataset makes the well-trained ML models more generalizable, compared with the group contribution theory. The efficiency of a feed-forward neural network model is further demonstrated by applying it to a hypothetical polyimide dataset of more than 8 million chemical structures. The predicted FFVs of hypothetical polyimides are further validated by MD simulations. The obtained FFVs of the 8 million polymers, plus their previously reported gas separation performances, demonstrate the promising capability of ML virtual screening for the discovery of polymer membranes with exceptional permeability/selectivity. © 2022, The Authors.

The effects of surface coating of cellulose II-based micro-fibrillated celluloses (MFCs) prepared with high concentration alkali treatment with/without co-solvent and then subsequent grinding were investigated in terms of physical properties of the coated papers. It was found that both of cellulose i MFC and cellulose II MFCs improved paper strength with increasing the pick-up of the MFCs. A similar magnitude of increase in paper strength was observed between cellulose I MFC and cellulose II MFCs. Optical properties of paper were slightly impaired with surface coating of MFCs. The papers coated with cellulose II MFCs showed a less color deviation and higher brightness than the papers coated with cellulose I MFC. No distinctive effect of co-solvent was found in strength and optical properties of the coated papers. The air resistances of the MFC coated papers were increased with the pick-up of MFCs. The papers coated with cellulose I MFC showed a higher air resistance than that with cellulose II MFCs at a given pick-up due to the more fibrillated nature of cellulose I MFC. © 2019 Korean Technical Assoc. of the Pulp and Paper Industry.

This research was conducted to manufacture the recording paper with hydrophobicity by gas chromatography grafting reaction varying the concentration of palmitoyl chloride, followed by determination of hydrophobicity, physical properties, biodegradation and printability of paper. The hydrophobicity of recording paper was improved as the concentration of palmitoyl chloride increased even though both tensile and burst strengths reduced slightly at 2%. Both optical property and printability remained. The higher the hydrophobicity of the paper, the lower the growth rate of bacteria. From these results, it is concluded that the gas chromatographic grafting technology is applicable to the manufacture of the recording paper with good hydrophobicity. © 2019 Korean Technical Assoc. of the Pulp and Paper Industry.
