Nacre‐Inspired Metal‐Organic Framework Coatings Reinforced by Multiscale Hierarchical Cross‐linking for Integrated Antifouling and Anti‐Microbial Corrosion

Advanced Functional Materials, Год журнала: 2023, Номер 33(47)

Опубликована: Июль 26, 2023

Abstract A long‐standing quest in marine materials science has been the development of tough and effective antifouling coatings for diverse surface protection. However, most commercial are severely limited by poor mechanical behavior unsustainable passive biocidal effect, leading to irreversible biofouling even microbiologically influenced corrosion (MIC). Herein, inspired amorphous/crystalline feature within nacreous platelets, a mechanically robust coating composed biopolymer‐based hydrogel dense metal‐organic frameworks (MOFs) is developed. Tailoring cross‐linked networks across multiscale interfaces can furnish strength, dissipate strain, improve toughness building blocks, resulting firm scalable configuration on various substrates regardless material category topology. The resultant as suitable reservoir exhibits unique active defensive intelligent MOF degradation or drug release, enabling groundbreaking performance broad‐spectrum control. Notably, neither attachment organisms nor MIC metal observed aggravated during prolonged testing process complex biological environments. This study provides distinctive insights into underlying multimechanisms comprehensive anti‐fouling‐corrosion pioneer rational strategy design next‐generation reliable MOFs‐derived

Accelerated Microbial Corrosion by Magnetite and Electrically Conductive Pili through Direct Fe⁰‐to‐Microbe Electron Transfer

Angewandte Chemie International Edition, Год журнала: 2023, Номер 62(38)

Опубликована: Авг. 1, 2023

Electrobiocorrosion, the process in which microbes extract electrons from metallic iron (Fe0 ) through direct Fe0 -microbe electrical connections, is thought to contribute costly corrosion of iron-containing metals that impacts many industries. However, electrobiocorrosion mechanisms are poorly understood. We report here electrically conductive pili (e-pili) and mineral magnetite play an important role electron transfer between Geobacter sulfurreducens, first microbe has been rigorously documented. Genetic modification express substantially diminished corrosive pitting rates -to-microbe flux. Magnetite reduced resistance transfer, increasing currents intensifying pitting. Studies with mutants suggested promoted a manner similar outer-surface c-type cytochrome OmcS. These findings, fact common product corrosion, suggest potential positive feedback loop produced during further accelerating electrobiocorrosion. The interactions e-pili, cytochromes, demonstrate mechanistic complexities electrobiocorrosion, but also provide insights into detecting possibly mitigating this economically damaging process.

Burning question: Are there sustainable strategies to prevent microbial metal corrosion?

Microbial Biotechnology, Год журнала: 2023, Номер 16(11), С. 2026 - 2035

Abstract The global economic burden of microbial corrosion metals is enormous. Microbial iron‐containing most extensive under anaerobic conditions. Microbes form biofilms on metal surfaces and can directly extract electrons derived from the oxidation Fe 0 to 2+ support respiration. H 2 generated abiotic also serves as an electron donor for respiratory microbes. metabolites accelerate this oxidation. Traditional strategies curbing include cathodic protection, scrapping, a diversity biocides, alloys that protective layers or release toxic ions, polymer coatings. However, these approaches are typically expensive and/or limited applicability not environmentally friendly. Biotechnology may provide more effective sustainable solutions. Biocides produced with microbes be less eukaryotes, expanding environments potential application. Microbially surfactants diminish biofilm formation by corrosive microbes, quorum‐sensing inhibitors. Amendments phages predatory bacteria have been successful in attacking laboratory studies. Poorly deposit extracellular polysaccharides minerals protect surface their metabolites. Nitrate amendments permit nitrate reducers outcompete highly sulphate‐reducing reducing corrosion. Investigation all mitigation its infancy. More study, especially relevant conditions, including diverse communities, warranted.
