Summary: DIET can enhance syntrophic propionate oxidization efficiency under room temperature conditions (20 degrees C). The microbial communities in GAC- and magnetite-supplemented reactors were similar, but different from the control reactor. Co-occurrence network revealed the syntrophic propionate-oxidizing bacteria and methanogenesis partners, such as Methanobacterium correlated with Smithella, Syntrophobacter, Dechloromonas, and Trichococcus.

Summary: This study compared two different strategies for acclimating the anaerobic digestion microbiome to increasing ammonium concentration. Results suggest that long-term cumulative exposure to ammonia disrupted the microbiome more strongly than direct (independent) ammonium additions. Different bioindicators with varying NH4+ tolerance capacity were identified among VFA producers and syntrophic VFA oxidizers.

Summary: In this study, a domesticated syntrophic consortium (MC) combined with coconut shell-derived biochar was used to alleviate ammonia inhibition in anaerobic digestion. The results showed that the combination of MC and biochar restored ammonia inhibition in 10 days and achieved a higher methane yield. This was attributed to the promotion of key microorganisms and enzyme genes by biochar.

Summary: Microbial communities in the anaerobic digestion of tannery and associated slaughterhouse effluent were studied in terms of their structure, function, and response to physicochemical variables. The results showed that the composition of methane-producing and sulfide-producing microbial communities changed initially but stabilized after the start of biogas generation. Continuous stirring favored the metabolically versatile genus Methanosarcina and resulted in higher methane production.

Summary: This study investigated the microbial ecology of granule formation in high-rate, up-flow anaerobic bioreactors and proposed an ecological granulation model. By analyzing the microbial communities actively undergoing growth, breakage, and reformation within the granules, important ecological roles influencing granule formation and stability were identified, leading to the development of a stepwise ecological model for granulation.

Summary: This study investigated the method of using different modified biochars to improve CH4 emissions and associated archaea in rice paddy soil. The results showed that nitric acid-treated biochar significantly suppressed CH4 emissions and increased CO2 emissions in soil. Additionally, the addition of biochars inhibited the accumulation of acetate and H-2 in rice paddy soil. 16S rRNA gene sequencing revealed that biochars amendment increased alpha-diversity of archaeal community and the modified biochars could mitigate the loss of alpha-diversity in the early stage of anaerobic incubation.

Summary: A global meta-analysis was conducted to investigate the effects of biochar on soil microbial communities, showing that biochar addition can increase arbuscular mycorrhizal fungal abundance and microbial biomass C, while decreasing soil respiration and actinomycetes abundance. The study also revealed that fungal abundance is the dominant factor affecting the response of bacterial abundance to biochar addition.

Summary: This study examines the relationship between supplier concentration and R&D investment of Chinese firms. The empirical results reveal a significant negative relationship between supplier concentration and firms' R&D expenditure, and the negative impact of supplier concentration on R&D investment is stronger for firms with weaker market power. This paper enriches the literature on corporate R&D investments, supply chains, and market power, and has important practical implications for developing country firms and policymakers.

Summary: This study achieves high-efficiency Tb-to-Eu energy transfer (>90%) in Eu/Tb bimetallic lanthanide coordination polymers with ultralow Eu3+ proportion (<6%). As a sensor, the yellow-light-emitting material exhibits visible luminescence behavior for micromolar-level detection of L-phenylalanine in water and serum, with high selectivity and competitiveness determined by an updated Stern-Volmer equation. The excited-state inter-ligand photon transfer is found to greatly contribute to the superior energy transfer and luminometric behavior of the material.

Summary: CsPbBr3 perovskite nanocrystals have promising potential for photocatalysis. However, their conversion efficiency is hindered by material instability and the accumulation of deactivated perovskites. To address this, a mechanochemical grinding approach with oleylamine as an additive was developed to restore the optical properties and photocatalytic activity of deactivated CsPbBr3. The regenerated nanocrystals showed comparable optical properties to the pristine ones and achieved a conversion efficiency of 88.7% in the photocatalytic CO2 reduction reaction. This method enhances CsPbBr3 utilization and provides a novel approach for perovskite material recycling, reducing material waste and environmental pollution.

Summary: Developing efficient photocatalysts for selective oxidation of benzene to phenol is challenging. In this study, a CuO@CN photocatalyst was fabricated by loading tubular carbon nitride with CuO nanoparticles thermally polymerized from Cu-based MOFs. The fabricated nanocomposite demonstrated 99.9% benzene photoconversion and 99.1% phenol selectivity under AM 1.5 illumination for 12 h. The excellent stability and sluggish photocharge carrier recombination rate indicate that this nanocomposite is an ideal photocatalyst for benzene oxidation.

Summary: This study found that strains B5 and B6 had strong inhibitory effects on various pathogens and significantly inhibited mycelium growth. They were identified as Bacillus velezensis through morphological features, biochemical determinations, and gene sequence analysis. Applying different concentrations of the bacterial suspension to cabbage seeds resulted in increased hypocotyl and taproot length. The in vivo results showed that B6 had better performance in reducing the incidence of cabbage seedling wilt disease. Furthermore, B6 had the ability to colonize cabbage plants and rhizosphere soil.

Summary: This study presents a movable electrical heating radiator with the function of user's temperature tracing and constant temperature control to enhance the thermal comfortable of the users. The system was modified by the previous studies in our laboratory. The control unit engaged Holtek HT66F2390 which is a newly designed microcontroller in China. The thermal sensing camera detected the user's temperature and transferred the data to microcontroller to move and follow the user up. The results display the reliable performance of system operations. The better distance between user and the traditional heat radiator is 150 to 250 cm. However, the distance might too long in a small space or room. Therefore, we reduce the distance to 50 cm and keep the thermal comfortable by PID control of output heating power of the radiator.
