Summary: This study provides important insights into the colonization of functional groups involved in lactate metabolism and butyrate production in the first two years of life. The research revealed dynamic changes in the gut microbiota of infants, with a switch from Veillonella producing propionate in the first year to Anaerobutyrycum hallii producing butyrate in the second year. Additionally, the weaning period between 6 and 10 months was identified as a significant time for an increase in butyrate producers and fecal butyrate concentration. Correlation analyses also suggested the metabolic cross-feeding of hydrogen in infants, which is a new finding in this study.

Summary: The impact of the window-to-wall ratio (WWR) on the energy demand of buildings in different locations of China was investigated using the energy balance equation. The study found that despite variations in climate and energy demands, the change rate of air conditioning and heating loads was similar with the same change in WWR. Furthermore, the heating and cooling loads were linearly related to WWR.

Summary: There is currently significant interest in studying the energy involved in products and services, particularly when novel energy resources are used. Unfortunately, there is no universally accepted procedure for evaluating this. This paper suggests a new evaluation method based on the stocks/flows-funds/services production model, which can accurately determine the energy flows involved in a technology. The paper also provides specific recommendations for using this model and presents a case study on electrolytic H2 production using photovoltaic electricity.

Summary: In order to expand the zero-energy building, it is important to evaluate the economic feasibility of passive and active elements. This study aims to verify the energy consumption and investment cost of a building based on changes in passive and active elements. The study calculated the final energy consumption for different regions using simulations and analyzed the investment cost according to changes in energy consumption and production. The results showed that investing in passive elements was more reasonable in the central region of Korea, while investing in active elements was more economical in the southern region.

Summary: With the urgent drive for carbon neutrality and strict climate policies, the H-2 shaft furnace (H-2-SF) is gaining attention in the steel industry. A one-dimensional mathematical model was used to study the performance of the H-2-SF with a dual-row injection top gas recycling system. Results showed that increasing the upper-row injection rate and microwave power can improve furnace performance, with the latter promising greater energy efficiency and a decrease in total energy demand by about 0.2 GJ/t-Fe.

Summary: The linkage of neighboring multi-energy microgrids can overcome the disadvantage of a single microgrid by achieving internal balance and self-sufficiency of surplus/deficient energy. This study proposes a bi-level optimization model that combines two trading modes: an intermediary agent-based trading mode and a direct trading mode. The price determination is based on the Stackelberg game theory and the supply/demand ratio method. The integrated demand response is also considered. The results of a comparative study in a neighboring energy cluster show that clustering increases total benefits compared to individual microgrids and helps in developing tailored policy instruments. Direct trading among microgrids yields higher benefits, but its self-sufficient ability is lower compared to trading with an intermediary agent.

Summary: Tumor-related mRNA detection is significant and interesting, but current methods face challenges in quantifying long mRNA sequences. In this study, a Y-shaped DNA probe with three target-binding segments was developed to overcome this limitation. The probe exhibited a low detection limit of 17.53 nM and high accuracy due to the benefits of three target-binding segments.

Summary: High entropy pyrochlores show potential as dispersoids in oxide dispersed strengthened steels or alloys for nuclear reactors and supercritical boilers. Y-2(TiZrHfMoV)(2)O-7 was synthesized with a nanocrystalline form and optimized to have lower crystallite and particle sizes. Different compositions showed variations in hardness and Young's modulus, with 4C-V having the highest hardness and 4C-Zr having a higher Young's modulus compared to other single-phase compositions.

Summary: The study showed that Resveratrol butyrate esters (RBE) can suppress obesity and lipid accumulation caused by Bisphenol A (BPA) exposure in female offspring rats, optimize blood lipids, and modulate intestinal microbiota. RBE demonstrated excellent potential for perinatological research due to its regulatory effects on body weight, blood lipids, and gut microbiota in the offspring rats exposed to BPA.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.

Summary: This study investigated the impact of magnetite on the nitrogen cycle of pig manure biostabilisation. The addition of magnetite increased N2O emissions and decreased NH3 emissions during composting. It also increased the total nitrogen content but should be considered for its significant increase in N2O emissions in engineering practice.

Summary: This study investigated the operation of a 1000L microalgae-based membrane photobioreactor system for continuous secondary wastewater treatment. The research focused on a green microalgae strain called Desmodesmus sp. The study aimed to understand key trends and optimization strategies by conducting experiments in both summer and winter seasons. The findings showed that maintaining low cell concentrations during periods of light inhibition was beneficial for nutrient uptake rates. Effective strategies for enhancing algae-based wastewater treatment included cell mass recycling and adjusting dilution rates based on light availability.
