Summary: Biogenic corrosion of concrete in wastewater systems is a global problem that causes extensive damage and costly maintenance. It is primarily caused by the colonization of sulfur-oxidizing bacteria on concrete surfaces, leading to the formation of sulfuric acid. Despite research efforts, a solution to this problem remains elusive.

Summary: The aim of the research was to assess the amount of extraneous water inflow to the system, with a focus on accidental water and infiltration water. Five quantitative approaches were used, and the results showed that infiltration water was the main source of extraneous water. The share of infiltration water varied depending on the year and the method used, while the share of accidental water was consistently smaller. The study provides valuable insights into the composition and volume of extraneous water in the sewage system.

Summary: The design of wastewater system pipe size is traditionally based on the maximum wastewater flow, which is a function of multiple factors. Understanding appropriate peaking factors by analyzing daily flow variations through wastewater collection systems is crucial for cost-effective design. This study in Antalya, Turkey, analyzed wastewater data from four residential areas to determine maximum and minimum peaking factors, proposing a new empirical equation for estimating the maximum daily peaking factor.

Summary: This study investigated the dynamic occurrence of 24 typical antibiotics in urban sewerage throughout a whole year. It was found that a significant number of samples had a high concentration of antibiotics, with sulfonamides, lincosamides, macrolides, and tetracyclines being the most common categories. The concentration of beta-lactams showed a tendency of attenuation in sewerage due to its degradability. The study also revealed a positive correlation between the total concentration of antibiotics in sewage and the dosage prescribed by local hospitals, indicating that sewage surveillance can provide valuable information on antibiotic usage.

Summary: This study aims to define the appropriate target level of public infrastructure asset management by combining consumers' expected level of service and complaint data. The case of the inland flood management project in South Korea is investigated, and it is found that people want to allocate 25% of their current monthly sewage bill on the management project. The results also show that people prefer to address the problems caused by old service infrastructure at a lower cost during early stages.

Summary: This study establishes a combinatorial library composed of 150 molecular weight-defined gemini amphiphiles (GAs) to identify carriers that facilitate robust cytosolic delivery of proteins. The top candidate efficiently translocates a broad spectrum of proteins into the cytosol, primarily through lipid raft-dependent membrane fusion, bypassing the classical endocytic pathway. This study reveals a GA-based small-molecule carrier platform for the direct cytosolic delivery of various types of proteins for therapeutic purposes.

Summary: This study investigated the porous media flooding mechanism of a hydrophilic nano-SiO2 enhanced emulsification system. The results indicate that the addition of nano-SiO2 effectively reduces interfacial tension, adsorption loss, and droplet size, resulting in improved concentration of emulsifier and enhanced emulsification of heavy oil. The stability of the emulsion is also enhanced, and oil recovery efficiency is increased by 21.95%. Both experimental setups demonstrate that the combined system not only expands the swept volume but also improves oil displacement efficiency, indicating a significant improvement in oil recovery.

Summary: Bisphenol A (BPA) is a concerning chemical due to its endocrine disrupting function, high production volume, and persistence in aquatic environment. A physiologically-based toxicokinetic (PBTK) model was modified to accurately simulate the fate of BPA in fish. The experiments showed that BPA metabolism in fish is not only limited to the liver, but plasma and gills may also play a role.

Summary: Despite their wide use in various fields, the knowledge about surfactants in environmental solid matrices is generally limited. Aiming to develop an extraction method in sediments for the simultaneous analysis of anionic, cationic, and non-ionic surfactants, this study compared different extraction techniques, solvents, and additives. The optimized method, coupled with liquid chromatography and tandem mass spectrometry, was validated and applied to real samples, allowing the detection of 18 out of 27 targeted surfactants.

Summary: Ultrasmall inorganic nanoparticles have gained significant attention in recent years for their beneficial biodistribution, pharmacokinetics, and theranostic properties. AGuIX nanoparticles made of polysiloxane and gadolinium chelates have been successfully translated for clinical use. In aqueous mediums, these nanoparticles are in dynamic equilibrium with polysiloxane fragments due to the hydrolysis of Si-O-Si bonds. High-performance liquid chromatography coupled with electrospray ionization mass spectrometry has enabled the separation and identification of these fragments.
