Summary: PAHs, potentially genotoxic and carcinogenic compounds, are mainly derived from incomplete combustion and pyrolysis of organic matter. Coffee, a widely consumed beverage, may contain PAHs due to roasting processes. To ensure the safety of this popular commodity, control over the entire production chain is essential.

Summary: Manganese dioxide (MnO2) with nanoflower morphology and high concentration of oxygen vacancies showed enhanced removal performance of polycyclic aromatic hydrocarbons (PAHs) in aqueous phase. The removal mechanism involved oxidation by non-radical Mn species and superoxide radical (O-2(-center dot)), leading to the formation of degradation products. The synergistic effects of oxygen vacancy and Mn3+ promoted the efficient degradation of PAHs.

Summary: This laboratory study examines the potential of two innovative laccase-mediator systems in removing PAHs from contaminated field soil. The results show that laccase in combination with TEMPO can degrade accessible PAHs, while HBT can mobilize desorption resistant PAHs. However, neither of the enzyme-mediator systems can effectively degrade inaccessible PAHs. Additionally, hydroxyl radicals generated by Fenton's reaction can reduce the desorption resistant fraction of certain PAHs.

Summary: Here, a facile and selective synthesis of cationic azatriphenylene derivatives was achieved through electrochemical intramolecular cyclization, where the key step involves atom-economical C-H pyridination without a transition-metal catalyst or an oxidant. This proposed strategy provides a practical approach for introducing cationic nitrogen (N (+)) into pi-electron systems, thus expanding the molecular design of N (+)-doped polycyclic aromatic hydrocarbons.

Summary: In this study, CeO2-based porous carbonaceous frameworks (CeO2 PCFs) were used as antioxidant nanozymes to scavenge reactive oxygen species and absorb benzo[a]pyrene. CeO2 PCFs exhibited excellent superoxide dismutase-like and catalase-like activity, effectively eliminating superoxide radical, hydroxyl radical, and hydrogen peroxide. The 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) free radical scavenging assay confirmed the free radical scavenging ability of CeO2 PCFs. Furthermore, CeO2 PCFs with large surface area and porous structure efficiently adsorbed benzo[a]pyrene. The designed CeO2 PCFs can serve as new antioxidant nanozymes for scavenging reactive oxygen species and adsorbing polycyclic aromatic hydrocarbons (PAHs).

Summary: This study evaluates the impact of seismic forces on the design of frame-type supporting structures for elevated water tanks (EWTs), and assesses the influence of fluid-structure interaction (FSI) on the overall structural response. Validation of the finite element model and push-over analysis are conducted to evaluate the performance of EWTs. Incremental dynamic analysis is then performed to investigate the influence of including FSI in the EWT analysis. The seismic design of the staging contributes to improvements in stiffness and ductility, and the inclusion of FSI introduces nonlinearity and can significantly change the structure's response.

Summary: Most international design standards have restrictions or requirements for seismic analysis and design of building frames with vertical irregularities. However, the existing irregularity quantifiers do not show a strong correlation with seismic impact risk. This study investigates the correlation between regularity index and seismic resilience index, seismic vulnerability index, and fragility functions for four types of vertically irregular buildings. The results show that building frames with in-plane discontinuity are the most vulnerable and have the highest risk among the selected structures.

Summary: This study investigates the environmental fate of non-steroidal anti-inflammatory drugs (NSAIDs) in the urban water cycle, evaluates their removal efficiency in sewage treatment plants (STPs), and assesses the ecological risk of these drugs using teratogenic index (TI) and risk quotient (RQ). The study finds that NSAIDs, including ibuprofen, naproxen, ketoprofen, diazepam, and diclofenac, are present in high concentrations in urban areas and persist in the water cycle. Some of these drugs pose teratogenic and lethal embryo risks. Therefore, it is crucial to monitor and minimize their discharge to protect human and environmental health.

Summary: Short-term streamflow prediction plays a crucial role in flood early warning and water resources management. Data-driven approaches have gained popularity in recent decades due to the digital revolution. In this study, multiple linear regression (MLR) and random forest (RF) models were developed and evaluated for short-term streamflow prediction using hydrological datasets from the Kulim River catchment in Malaysia. The results showed that including more precedent streamflow events as predictors improved the performance of data-driven models, especially in predicting peak streamflow during high-flow events. The RF model outperformed the MLR model in overall prediction accuracy but showed decreased accuracy in predicting the arrival time and magnitude of peak streamflow with increasing lead-time length.

Summary: This research examines the performance of a Malaysian Ganoderma lucidum strain in degrading chemical oxygen demand (COD) and ammonia in synthetic wastewater, as well as the effect of agitation speed and carbon-to-nitrogen (C/N) ratio. The study finds that at an agitation speed of 100 rpm, COD and ammonia can be removed by 95% to 100% within 30 hours. Microscopic analysis confirms structural changes in G. lucidum after wastewater treatment, suggesting its potential in treating synthetic domestic wastewater with high organic content.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
