Summary: Catalytic asymmetric de Mayo reaction was achieved for the first time under visible light using asymmetric binary acid catalysis (ABC) involving zirconium chloride and chiral phosphoric acid (CPA). The chiral zirconium catalysis enables effective reactions over a broad range of 1,3-diketones and alkenes with up to >99% yield and 98% ee. The key chiral zirconium enolate was isolated and characterized to account for the observed catalysis and stereoselectivity.

Summary: A porous geopolymer with adsorption and photocatalytic degradation functions was developed using Ti-bearing blast furnace slag (TBBFS) as the raw material. The modified TBBFS through selective crystallization and water quenching methods showed high adsorption capacity and bifunctionality in adsorption-photodegradation. The presence of CaTiO3 in the geopolymer matrix enhanced the formation of hydroxyl radicals, leading to superior removal efficiency for methylene blue.

Summary: This study finds that the water column plays an important role in nitrogen cycling processes in rivers, which is often neglected. Observations across six river networks in China show that the water-air and sediment-water fluxes of N-2 and N2O decrease, while the water column production increases with stream order. The water column contribution increases with stream order and accounts for more than 50% in rivers above fifth order. Neglecting water column processes would lead to an underestimation of N removal and N2O emissions by approximately 50% for these river networks.

Summary: This study found that zebrafish can absorb hydrophobic organic compounds (HOCs), such as polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs), through dermal uptake. The dermal uptake is an important pathway for HOCs bioconcentration in fish, and should be considered in the study of toxicodynamics and toxicokinetics of HOCs.

Summary: This study investigated the bioaccumulation and fractionation of 11 PFAAs along an aquatic food chain. The results showed that shorter chain PFAAs had lower proportions in organisms compared to exposure water, while longer chain PFAAs had higher proportions. Predation promoted these fractionation differences, with shorter chain PFAAs being replaced by their longer chain analogues. This study highlights the importance of considering fractionation in studying the environmental behaviors and ecological risks of multiple PFAAs.

Summary: Humic substances (HSs) significantly influence the transport and bioavailability of hydrophobic organic compounds (HOCs) in soils. This study investigated the sorption behavior of HOCs by different HS fractions in soils from different climatic zones. The results showed that HSs from colder climatic zones exhibited higher sorption affinity and different compositions compared to those from warmer climatic zones. The findings highlights the importance of considering the sorption differences of HOCs to HSs among different climatic zones in predicting HOC fates and bioavailability in soils.

Summary: This study investigated the microbial sources of nitrous oxide (N2O) in rivers and the degree of N2O reduction. The findings suggest that nitrification and nitrifier denitrification are the dominant processes controlling N2O production in rivers, and intense microbial reduction significantly contributes to the low N2O emissions observed. The production and consumption of N2O in rivers should be considered in future research.

Summary: In this study, it was found that warming increases the bioaccumulation of per- and polyfluoroalkyl substances (PFAS) in pelagic organisms due to increased water concentrations. However, warming did not significantly affect PFAS accumulation in benthic organisms, except for certain types, which was consistent with declined sediment concentrations. The findings highlight the importance of considering the media-specific effects of temperature on PFAS concentrations in ecological risk assessments under climate change.

Summary: The constituents and functionality of urban inland waters are disturbed by municipal sewage inputs and tailwater discharge from wastewater treatment plants, leading to significant perturbations in greenhouse gas dynamics. A lack of in situ measurements has resulted in large knowledge gaps in this understanding. Through a 3-year field campaign, the CO2 emission and related factors in the municipality of Beijing were investigated, revealing unique greenhouse gas emission profiles and emphasizing the importance of accounting for urban inland waters in terms of aquatic greenhouse gas emissions.

Summary: Positively charged nanoplastics induce stronger growth inhibition and gut damage in Chironomus kiinensis larvae compared to negatively charged nanoplastics. This is because the positively charged nanoplastics accumulate more readily in the gut, causing more severe oxidative stress, epithelial damage, and inflammatory responses. The positively charged nanoplastics also have a lower agglomeration rate, leading to increased interaction with gut cell membranes and microbiota. Furthermore, exposure to positively charged nanoplastics results in lower alpha diversity and relative abundance of key gut microbiota, exacerbating gut and growth damage.

Summary: This study found that electrical conductivity is a reliable indicator for assessing the effect of land use types on stream N2O concentrations. It reflects the different levels of N2O concentration and flux in streams across different land uses. Higher electrical conductivity is associated with higher carbon and nutrient levels, as well as abundance of N2O-producing microbes. Electrical conductivity also has the potential to indicate the magnitude of exogenous N2O input across different land uses.

Summary: The influence of light irradiance on N2O emissions in river systems was studied. It was found that light inhibited N2O emissions in the ammonium system and significantly reduced N2O emissions in the nitrate system. Higher light conditions in the nitrate system led to increased N2O reduction and decreased N2O production, resulting in lower N2O emissions.

Summary: This study investigated the bioaccumulation of polycyclic aromatic hydrocarbons (PAHs) in different tissues of zebrafish. It was found that there was variation in the concentrations of PAHs in different tissues, with the highest concentration observed in the skin and the lowest concentration in the fish muscle. The distribution of PAHs was related to lipid content in the tissues, but this correlation was not significant. The study also demonstrated that the physiological based toxicokinetic (PBTK) model could accurately predict PAH concentrations in different fish tissues.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.
