Summary: Rigidifying the gold-thiolate shell is an effective strategy to enhance the fluorescence of gold nanoclusters (GNCs). In this study, ultrabright lysozyme-functionalized 5-methyl-2-thiouracil gold nanoclusters (MT-LZ@GNCs) were synthesized and exhibited remarkable luminescent properties. By combining MT-LZ@GNCs with iron-doped carbon-nanosheet (Fe/C NS) mimicking peroxidase-like activity, a novel fluorescent nanoprobe was developed for the quantitative analysis of xanthine. The proposed sensing platform showed a wide detection range and a low detection limit, with potential applications in real sample monitoring.

Summary: Air quality in eastern China has improved in recent years, but severe haze pollution still occurs in winter. This study developed a random forest model to predict the optical extinction levels in eastern China from 2014 to 2019, and found a shrinking trend in optical extinction, with the highest levels in North China. The decreasing trends of optical extinction were slower than those of PM2.5 mass concentrations, possibly due to the increase in secondary aerosols.

Summary: Water scarcity and quality deterioration are common in economically developing regions, and selecting priority areas is an effective strategy to mitigate water crises. This study proposes a novel framework that considers the interaction between aquatic and terrestrial ecosystems to predict the effects of climate change and human activities, and selects priority areas for multiple water-related ecosystem services. The results of a case study in China show that the conservation efficiency of the priority areas decreased as climate change accelerated, and the selection of priority areas was influenced by precipitation, temperature, and topographic factors.

Summary: This study explored a novel approach to removing thiacloprid from agricultural soil using straw biochar-loaded iron and manganese oxides for persulfate activation. The results showed that a removal rate of 75.22% could be achieved within 7 days using 3% FeMn@BC and 2% persulfate, and a removal rate of 92.50% could be achieved within 60 days. Additionally, the FeMn@BC/PS group increased the levels of ammonium nitrogen and available potassium in the soil, as well as the activity of urease and phosphatase. Moreover, the FeMn@BC/PS group alleviated the damage to the soil microbial community caused by thiacloprid. The findings of this study provide a new insight into advanced oxidative remediation of soils.

Summary: Pt/C and SO42-/ZrO2 were used as catalysts for the synthesis of p-aminophenol through the catalytic transfer hydrogenation of nitrobenzene in water with formic acid as the hydrogen source. The optimal Pt loading for PAP selectivity was found to be 1 wt%. The presence of different valence states of Pt affected both the nitrobenzene hydrogenation and formic acid decomposition. Among different solid acid catalysts tested, SO42-/ZrO2 exhibited the highest catalytic activity for p-aminophenol formation. Under the optimized reaction conditions, the conversion of nitrobenzene reached 80.0%, with a selectivity of 47.6% for p-aminophenol.

Summary: The mechanism of the reaction between CO2 and styrene oxide for cyclic carbonate was revealed using density functional theory calculations. The noncatalytic reaction occurred via a concerted mechanism, while in the presence of guanidine and tetrabutylammonium iodide (TBAI) co-catalysts, the epoxide ring-opening by nucleophilic attack of an iodide anion was predicted to be the rate-determining step. Guanidine acted as the H-bond donor to activate styrene oxide, facilitating the reaction with a lower activation barrier.

Summary: Copper nanorods (Cu-NRs) exhibit significant plasmonic behavior and can act as efficient catalysts in redox processes and coupling. A benign decarboxylative approach, utilizing localized surface plasmon resonance (LSPR) assisted catalysis with Cu-NRs, has been developed for the production of alkane analogues from alkyl carboxylic acids under visible light. The catalyst shows a broad substrate scope and high functional group tolerance, without the need for an external oxidant or proton source. A plausible mechanism for this recyclable nano-catalyst has also been proposed based on control experiments.
