Summary: Anaerobic digestion of waste activated sludge is commonly used for stabilization, mass reduction, and resource recovery, but its performance can be hindered by poor digestibility and slow degradation rate. A series of bench-scale tests using an innovative electrochemical pretreatment method showed that destruction of the EPS matrix and anaerobic digestibility can be enhanced, with the most significant improvement observed at 15V for 1.5 hours. Economic analysis indicated that a 1-hour, 12V EPT is the most economically feasible option.

Summary: The study revealed that the efficiency of methane generation from waste activated sludge (WAS) can be significantly enhanced through pretreatment with isoelectric-point (pI), which improves the hydrophobic attractions at the solid-liquid interface and promotes electron transfer efficiency. The pI pretreatment also led to an increase in the relative abundances of main functional microbes related to hydrolysis, acidification, and methanation, contributing to an overall boost in methane production.

Summary: Producing MCFAs from simple substrates like ethanol and acetate showed rapid results, while using waste activated sludge (WAS) led to poor performance due to inefficient bacterial hydrolysis. Ethanol presence improved the process to some extent, with electron extraction primarily from ethanol rather than WAS observed in chain elongation microbial consortia.

Summary: The microbial community structure shift and the effect of H2 level on chain elongation performance were investigated in a long-term acclimation experiment. The study found that traditional anaerobic fermentation consortia could rapidly acclimate the chain elongation microbiome. The dominant bacteria during the operation were Caproiciproducens, Clostridium sensu stricto 12, Rummeliibacillus, and Oscillibacter. Increasing ethanol input led to H2 accumulation in the headspace, which immediately inhibited the oxidation of caproate and butyrate, but had a delayed inhibition effect on chain elongation. The H2 level in the headspace was positively correlated with MCFAs production-related bacteria, but excessive H2 accumulation might suppress MCFAs production in the long term.

Summary: Chain elongation is a promising technique for producing medium-chain fatty acids (MCFAs). However, the effects of CHCl3 and GAC on the production and microbial community of MCFAs still need further investigation. CHCl3 showed a detrimental effect on the chain elongation system, inhibiting homoacetogens and decreasing caproate production efficiency. GAC was found to have a negative impact on chain elongation with simple substrates, resulting in low caproate production.

Summary: This study proposed a novel enhancing strategy for achieving high-efficiency of bioenergy/bioresource recycle from anaerobic treatment of waste activated sludge (WAS) by using sludge source-redox mediators (SSRMs). SSRMs not only facilitated bioelectrogenesis and acidogenesis, but also improved electron transfer efficiency. Furthermore, SSRMs promoted the abundance of core members, microbial diversity, and community distributive evenness. This study provided an effective strategy for sustainable bioconversion of WAS to bioenergy/bioresource.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
