Summary: This research tests the efficacy of phosphonium ion gels in preventing biofouling and examines the impact of hydrophobicity and biocide concentration on anti-fouling performance. The study finds that formulations with higher hydrophobicity exhibit better anti-fouling performance, while the presence of copper(II) biocide negatively affects it. Furthermore, no correlation is observed between antimicrobial activity and anti-fouling performance.

Summary: In order to avoid biofouling formation in a closed-photobioreactor (PBR), a non-toxic coating with high transparency is needed. Poly(dimethylsiloxane)-based coatings mixed with poly(ethylene glycol)-based copolymers have been found to inhibit microorganism adhesion, with the DBE-311 copolymer being the most effective option. However, the surface properties of these coatings change over time, allowing cell adhesion after 8 months of immersion. Complementing the XDLVO theory with models to predict conditioning film formation and the contribution of fluid dynamics over time is necessary.

Summary: With the increase in antimicrobial-resistant bacteria strains, finding new and effective ways to reduce bacterial infection rates is crucial. Superhydrophobic materials exhibit unique wetting properties that can minimize bacterial attachment points, making them effective in reducing bacterial adhesion. This study investigates the impact of surface design on the anti-biofouling capabilities of superhydrophobic pillared arrays prepared via photolithography. By varying pillar spacing, insights into the complex nature of superhydrophobic fouling are gained, allowing for optimization of antifouling performance. The optimal material achieved a 3-log reduction in bacterial attachment (>99.9%) at a pillar spacing of 87.5 μm.

Summary: The study investigated the fabrication of PDMS-coated nets using PDMS/hexane solution and how the dilution ratio affected the penetration of PDMS into the net yarn and the performance of the nets. It was found that a 2:1 and 1:1 ratio of PDMS to hexane showed the best performance. Additionally, the Shore hardness of PDMS had minimal impact on the biofouling control properties, while t-ZnO microparticles were effective in preventing photodegradation of the nylon nets.

Summary: A universal and facile method based on an amphiphilic copolymer was developed to immobilize an intraductal surface antifouling coating for a variety of polymeric catheters. The copolymer-modified intraductal surface was then infused with aqueous I-2 to form the PVP-I-2 complex, endowing the coating with bactericidal activity. The findings provide a new avenue toward facile and universal fabrication of intraductal surface antifouling catheters, offering a superior option for decreasing the consumable costs in industrial production and alleviating the pain of replacing catheters for patients.

Summary: Developing highly efficient bifunctional oxygen electrocatalysts is crucial for zinc-air flow batteries. Metal-organic frameworks (MOFs) and covalent organic polymers (COPs) have emerged as promising alternatives due to their designable and controllable atomic-level structures. However, their catalytic performances are limited by conductivity and catalytic activity. In this study, nanosheet FeNi-MOF and iron phthalocyanine rich COP hybrid materials are assembled through the pi-pi stacking effect to create highly efficient bifunctional electrocatalysts. The resulting catalyst exhibits superior catalytic performance and stability, making it a promising candidate for zinc-air flow batteries.

The modified e-CPA model demonstrated better performance and the hybridization with electrical conductivity models resulted in two predictive models for estimating the electrical conduction of dilute and concentrated electrolyte solutions. These predictive models showed relative average percentage deviations (AARD) of 11.15% and 13.87% over wide ranges of temperature and electrolyte concentration.
