Summary: The model predicts that severe fouling occurs at low ζ(2) values, and increasing ζ(2) can significantly reduce the membrane fouling rate. The role of contact angle θ is critical, as fouling is dramatically reduced when θ is below (or above) a certain threshold value.

Summary: This study investigated bacterial adhesion and growth behaviors on PVDF microfiltration membrane during biofouling development, showing that biomass abundance is crucial for biofouling occurrence. Bacteria growth on membrane surface followed a pseudo second-order kinetic equation and was mainly influenced by substrate concentration in the feeding. Interfacial energy decreased continuously between membrane and bacteria, impacting adhesion behavior, with potential for guidance on biofouling mitigation and control for membrane filtration.

Summary: In this study, a field-induced single-ion magnet behavior was observed in a Co(II) mononuclear complex synthesized by the hydrothermal method. The complex demonstrated a high effective energy barrier due to the long axial metal-oxygen coordination bond in a distorted elongated octahedron. This work deepens the understanding of the relationship between the effective energy barrier and the weak change of ligand field, which could facilitate the development of single-ion magnets with high energy temperatures.

Summary: Two raceway open ponds with volume of 5.5 liters each were used to assess the removal of organic material and nutrients from wastewater. Algal-bacterial flocs were utilized in the ponds to treat primary and secondary effluent. The hydraulic retention time gradually decreased from 5.5 to 2.2 days over a period of 21 days, and then both reactors operated at an HRT of 1.1 days. A high biomass concentration of around 2.2 g/L was sustained using primary and secondary effluent after 130 days. The biomass exhibited strong activity and could completely remove organic material and nutrients in less than 12 hours. Additionally, the algal-bacteria biomass had excellent settling properties, settling in less than 10 minutes.

Summary: This study aimed to explore the associations between attachment dimensions, shame subtypes, and primary and secondary psychopathic traits. The results showed that attachment anxiety and avoidance explained the largest variance for secondary psychopathic traits, while characterological shame had a direct and indirect effect on both primary and secondary psychopathic traits. These findings highlight the importance of studying psychopathic traits in community samples as a multidimensional construct, with a particular focus on assessing attachment dimensions and shame subtypes.

Summary: The study revealed different magnetization relaxation behaviors between Tb-diluted and Tb-rich apatite-type silicates, with the former showing comparable relaxation features with analogue compounds and Tb-doped calcium phosphate apatite, while the Tb-rich compound exhibited similar relaxation parameters to the Dy-based analogue. This represents the first instance of magnetization relaxation independence on the nature of a rare-earth metal ion in single ion magnet like materials.

Summary: The study investigated the impact of TEP pre-conditioning on the hydrophobicity and initial bacterial attachment of the FO membrane support layer. The results showed that the conditioning solution pre-treated with a 0.4 μm pore size filter contributed to the highest bacterial adhesion rates in both steady state and cross-flow mode in a lab-scale FO system for both membrane types. Additionally, the PA-TFC membrane exhibited a higher impact of fouling in cross-flow lab-scale testing compared to the CTA-ES membrane, attributed to its higher porosity and surface roughness.

Summary: Water disinfection is crucial for ensuring safe drinking water, particularly in the face of climate change. Chemical oxidants can form secondary oxidants during disinfection processes, which can cause additional damage to bacteria. This study reviews the complex interactions between reactive species in disinfection processes and their potential impact on disinfection effectiveness. It provides a quantitative overview of disinfection strength based on inactivation kinetics and typical exposures. The study also highlights the resistance of wild strains compared to lab-cultivated strains and discusses the role of secondary oxidants in pathogen inactivation, as well as possible defense responses of bacteria and other additional effects.

Summary: This study aimed to investigate the impact of patient characteristics, such as adult attachment, health status, number and severity of chronic conditions, and social support, on sleep disturbances in patients with multimorbidity. The results showed that attachment anxiety, poor social support, higher number of chronic conditions, and better general health status were all associated with higher levels of sleep disturbance after 12 months.

Summary: This study investigates the impact of future changes in atmospheric synoptic variability (ASV) on ocean properties and biogeochemical cycles in the tropical Pacific Ocean using coupled and forced atmosphere-ocean model experiments. Future climate projections show a decrease in ASV in subtropical gyres and an increase in the tropical band. Changes in ASV affect ocean circulation and tropical net primary productivity, highlighting the significance of ASV in understanding the impacts of climate change on ocean dynamics and biogeochemical processes.

Summary: This paper investigates the minimum ignition energy in lean fuel/air mixtures through simulations and experiments. The results show three different types of evolution: ignition failure, flame kernel formation with subsequent extinction, and flame propagation. The dependence of minimum ignition energy for flame propagation on the research octane number (RON) exhibits an upturn, which can be explained by different reaction pathways.

Summary: In this study, soy molasses were processed using Aspergillus niger enzymes to optimize the conversion of oligosaccharides to monomeric sugars. The effects of pH and temperature were investigated, and it was found that pH 4.8 and 60 degrees C were the optimal conditions for glucose and fructose release. Galactose production, however, was less effective and varied significantly. Model equations were developed to describe the kinetic sugar-release profiles and make technoeconomic analysis.

Summary: In this study, a highly effective surfactant producer strain, Bacillus Cereus GX7, was isolated from the oil tank bottom sludge of Shengli Oil Field in China. The biosurfactant produced by GX7 was identified as surfactin, a lipopeptide surfactant, through TLC, FT-IR, and LC-MS/MS analysis. The fermentation process of GX7 was optimized using single-factor experiments, focusing on the composition of fermentation medium and fermentation conditions. Glucose and peptone were found to be the best carbon and nitrogen sources, and the optimum temperature, inoculum amount, pH, rotation speed, and fermentation time for the strain were determined to be 30°C, 1%, 7.5, 150 rpm, and 48 h, respectively. After optimization, the surface tension and emulsification index of the fermentation broth were 26.84 mN/m and 57.84%, respectively. Furthermore, the biosurfactant produced by GX7 demonstrated good stability over a wide range of temperature, pH, and salt concentration.

Summary: Effective management of biofluids is crucial for in vivo surgical interventions. Recent advances include self-sealing needles, drug-eluting stents, and shear-thinning hydrogels. However, complications associated with intestinal mucosal injury and secondary damage still persist. In this study, researchers developed an interpenetrating Janus wettability stent coating that enables unidirectional draining of excessive biofluid. They also demonstrated directional biofluid movement using a self-pumping dressing with potential applications in biofluid collection and disease diagnosis through metal ion detection. This integrated system presents an opportunity for designing wound dressings with effective biofluid management and metal ion detection capabilities.
