Summary: In this study, two types of MFC sensors, MFC-A and MFC-B, were developed and compared. MFC-A showed superior performance in the detection of sodium acetate and glucose, as well as higher output voltage and power density compared to MFC-B. Confocal laser scanning microscopy and microbial-community analysis revealed a richer anode biomass for MFC-A. A novel method for simultaneous testing of individual concentrations of sodium acetate and glucose in a mixed solution was proposed and verified using the sensitivities of the two MFC sensors.

Summary: SGLT2 inhibitors not only lower blood glucose levels but also have protective effects on organs such as the heart and kidneys. These inhibitors prevent beta-cell dysfunction by reducing glucose overload, leading to increased beta-cell proliferation and decreased apoptosis. Clinical and preclinical data support the protective effect of SGLT2 inhibitors on beta-cell mass and function.

Summary: Microbial fuel cells (MFCs) have great potential for recovering electrical energy from waste and biomass, but their practical application is hindered by inefficient power production and high costs. In this study, a bacteria/electrospun oriented carbon nanofibers integrating with carbon nanotubes (BEO-CNFs/CNTs) anode was developed to enhance MFC performance. The BEO-CNFs/CNTs anode greatly improved bacterial loading content and extracellular electron transfer (EET) efficiency, leading to a significantly higher power density than other anodes. This research provides a new perspective for preparing efficient anodes using electrospinning technology.

Summary: This study compared the culture method using sodium acetate and glucose as organic carbon sources with autotrophy in Haematococcus pluvialis. In the 12-day culture, mixotrophy with sodium acetate and glucose increased biomass by 40.4% and 77.1% respectively compared to autotrophy, but the mechanisms were different. Mixotrophy with glucose increased biomass by directly supplying substrate and ATP to the TCA cycle while inhibiting photosynthesis. Gene expressions related to glycolysis and carbon fixation pathway were confirmed in autotrophy and mixotrophy with glucose and acetate. The proposed metabolism in mixotrophy with acetate and glucose was analyzed through autotrophic and heterotrophic metabolism.

In this study, a novel solar-assisted electrooxidation process (SEOP) was developed to degrade bisphenol S (BPS) using activated peroxymonosulfate (PMS) or peroxydisulfate (PDS). The results showed that SEOP with persulfate (PS) demonstrated a synergistic effect for BPS degradation and had lower energy consumption compared to other methods. Additionally, quantum chemical calculations provided insights into the reaction mechanism and active sites for BPS degradation.

Summary: In this study, heteroatom-doped carbon nanosheets were successfully synthesized using crosslinked triazine frameworks and g-C3N4 nanosheets as a template. The nanosheets exhibited high crinkling and interconnectivity, along with a large surface area (1060 m(2) g(-1)) and pore volume (2.14 cm(3) g(-1)), with highly dispersed N, O and S. When coated on commercial Celgard separators, the modified batteries showed low self-discharge and improved rate performance, even at 4 C. Excellent cycling performances were achieved at different rates, with an initial discharge capacity of 1240 mA h g(-1) and a capacity decay of only 0.059% per cycle for over 1000 cycles at 0.5 C.

Summary: In this study, a low-cost cathode catalyst based on a NiMo alloy was examined for hydrogen production in microbial electrolysis cells (MECs) as an alternative to noble metals. Two NiMo catalysts were synthesized, one through an electrochemical assisted (NiMo Elec) approach and the other through a hydrothermal (NiMo Ht) approach. The NiMo Ht method showed a higher concentration of Mo atoms in the electrocatalyst compared to the NiMo Elec approach, resulting in a similar current density and minimal overpotential compared to Pt. The high performance and low cost of the NiMo Ht catalyst make it an economically viable approach for biohydrogen generation in MECs.

Summary: This study investigated the transformation and reaction mechanisms of dissolved organic matter (DOM) during electrocoagulation (EC) and persulfate enhanced electrocoagulation (EC/PS) processes for bio-treated landfill leachate (BLL). The results showed that coupling persulfate with EC enhanced the removal efficiency of chemical oxygen demand (COD) and total organic carbon (TOC). The analysis of sediments generated by EC and EC/PS suggested that precipitation was the main contributor to DOM removal during the EC/PS process. These findings help understand the role of persulfate in landfill leachate treatment and reevaluate its advantages and limitations as an oxidant.

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.
