Summary: A total of 136 perishable waste primary products were sampled in nine cities in Zhejiang Province, China, to investigate their nutrient content and potential impact. The products were found to have high nutrient content (5.00% on average), but excessively high conductivity, total soluble salt content, and grease content. These excessive salt and grease levels may harm soil and crops, becoming limiting factors for perishable waste fertilizer utilization. Most samples met current commercial organic fertilizer standards for heavy metal content, except for lead and chromium levels in some samples. Toxic and harmful substances such as toluene, ethylbenzene, and m & p-xylene were commonly detected in the samples, posing risks to the safe use of perishable waste as fertilizers.

Summary: The cellular and tissue behavior of fishes in response to Iron oxide nanoparticles (IONPs) and their associations with agrochemicals were evaluated. The results showed that the accumulation of iron was greater in the IONP treatment group and the mixtures with GBHs. Tissue integrity assessments demonstrated an intense accumulation of lipids, formation of necrotic zones and leukocyte infiltrates in all the treated groups, with a greater quantity of lipids in the IONP + GLY and IFe groups. The damage caused to animal livers by IONP mixtures is reversible, providing promising results for safe environmental remediation practices using nanoparticles.

Summary: Incorporating nanofillers into elastomers leads to composites with great potential, but concerns arise due to agglomeration of fillers. Different carbon nanotube pretreatment methods were analyzed to improve filler dispersion in polydimethylsiloxane (PDMS)/CNT composites. While solvent dispersion led to increased electrical conductivity, it also caused a softening effect due to solvent residues. Chemical functionalization improved compatibility but damaged CNTs, overshadowing the conductivity and reinforcement enhancement effects.

Summary: This study evaluated the inhalation bioaccessibility and deposition of organic components in atmospheric particulate matter in a Chinese megacity. The study found that the bioaccessibility of organic components was influenced by their hydrophobicity and carbon content in the particles. Coal and biomass combustion, as well as traffic emissions, were negatively correlated with the bioaccessibility of organic components. The incremental lifetime cancer risk and non-cancer risk were estimated and found to be within acceptable ranges considering the bioaccessibility and deposition efficiencies.

Summary: Water treatment plays a crucial role in addressing global water shortages. Carbon nanotubes (CNTs) show great potential in environmental applications due to their unique physical and chemical characteristics. The utilization of functionalized CNTs and nanocomposites can effectively eliminate contaminants, although their high costs still limit their widespread implementation in water treatment.

Summary: The study found that nonmodified kenaf cellulose nanofiber (CNF) is a fibrous high aspect ratio nanomaterial with a negatively charged hydroxyl group, moderate particle stability, and high loading capability. Kenaf CNF showed high dispersion stability in freshwater conditions, did not cause abnormalities or mortality in D. rerio, and had no acute immobilization against D. magna. The EC50 and LC50 values for both organisms were above 100 mg/L, indicating that kenaf CNF is nonhazardous to the aquatic environment according to the Globally Harmonized System (GHS).

Summary: This paper systematically reviews 103 vehicular datasets covering naturalistic driving and self-driving tasks. The majority of naturalistic datasets focus on road safety and driver behavior, while datasets for autonomous driving are analyzed based on target self-driving tasks. The lack of relevant publicly available datasets for creating new risk assessment models for semi- and fully automated vehicles is highlighted, prompting a gap analysis to identify possible approaches.

Summary: This study demonstrates the application of machine learning algorithms to predict the antioxidant efficiency of nanomaterials. A comprehensive dataset was compiled based on a literature review, and various physico-chemical properties, synthesis techniques, and experimental conditions were used as input features for prediction. The random forest model showed the highest predictive performance, reaching an R-2 = 0.83, and the type, core-size, and dosage of the nanomaterials were found to be the most important attributes influencing the prediction. This study expands the application of machine learning in the nano-domain and highlights the lack of a comprehensive database and relevant data management practices in the field.

Summary: Generalized Linear Models (GLMs) and XGBoost are commonly used in insurance risk pricing and claims prediction. However, Deep Learning (DL) models, like TabNet, are underutilized in this field. This study compares TabNet, XGBoost, and Logistic Regression on claim prediction using a synthetic telematics dataset. TabNet outperforms the other models by providing highly interpretable results and accurately capturing the sparsity of claims data. Despite the longer running time and hyperparameter tuning required, TabNet offers better pricing models for interpretable insurance models compared to XGBoost and Logistic Regression.

Summary: Governance of nanotechnology, especially in terms of human and environmental concerns, is a controversial issue. The creation of risk governance framework and council has been pursued to address this. Public perception of nanotechnology tends to be positive, but there is a lack of awareness of potential risks among the general public. Social media has become a crucial tool for communication, but it can also lead to regulatory and economic reactions. Effective risk governance should include a social media blueprint to counter misinformation and mitigate the impact of social media-induced reactions.
