Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: July 3, 2024

Abstract Simultaneous high strength and toughness are highly sought‐after in lattice metamaterials, but these properties typically mutually exclusive. To overcome this challenge, the development of interpenetrating phase composite (IPC), which incorporates a net matrix infill into lattice, has shown great potential overcoming constraints is thus continuous practical interest. In work, novel aperiodic monotile truss polymer IPC that exhibit unprecedented enhancement both reported. Specifically, unit cell inspired by Einstein's monotile, single space‐filling shape where orientation never repeats. The IPCs achieved through 3D‐printed Ti‐6Al‐4V lattices epoxy infiltration. highest gain compressive reveals an impressive 246.61% increase, significantly exceeding “1 + 1 > 2” idealization associated with metamaterials. Furthermore, specific energy absorption 46.2 J g −1 demonstrates superior toughness. underlying mechanisms, including damage sequences, two‐phase interactions, geometric effects between epoxy, fully elucidated. Overall, work reports IPC's utilizing idealized structures to achieve optimal combination mechanical

Dual‐Protection Inorganic‐Protein Coating on Mg‐Based Biomaterials through Tooth‐Enamel‐Inspired Biomineralization

Advanced Materials, Journal Year: 2024, Volume and Issue: 36(21)

Published: Feb. 10, 2024

Abstract Biocompatible magnesium alloys represent revolutionary implantable materials in dentistry and orthopedics but face challenges due to rapid biocorrosion, necessitating protective coatings mitigate dysfunction. Directly integrating durable onto Mg surfaces is challenging because of intrinsic low coating compactness. Herein, inspired by tooth enamel, a novel highly compact dual‐protection inorganic‐protein (inorganic Pro ) situ constructed on through bovine serum albumin (BSA) protein‐boosted reaction between sodium fluoride (NaF) substrates. The association ions BSA establishes local hydrophobic domain that lowers the formation enthalpy NaMgF 3 nanoparticles. This process generates finer nanoparticles function as “bricks,” facilitating denser packing, consequently reducing voidage inside over 50% reinforcing mechanical durability. Moreover, incorporation plays two synergistic roles: 1) acting “mortar” seal residual cracks within coatings, thereby promoting compactness tripling anticorrosion performance, 2) mitigating fouling‐accelerated biocorrosion complex biosystems via tenfold resistance against biofoulant attachments, including biofluids, proteins, metabolites. innovative strategy, leveraging proteins alter inorganic reactions, benefits future design for Mg‐based other metallic with tailored antifouling performances.

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

Microbial Biotechnology, Journal Year: 2023, Volume and Issue: 16(11), P. 2026 - 2035

Published: Oct. 5, 2023

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.

Published: Jan. 1, 2024

Inhibiting the adhesion and growth of marine microorganisms through photocatalysis is a potentially efficient environmentally friendly antifouling strategy. However, undesired "shading effect" caused by resin coatings microbial deposition reduces utilization catalysts leads to failure in active substance on coating surface. Here, we successfully developed composite (DPC-x) combining g-C3N4 nanosheet (g-C-NS) photocatalysts with degradable green poly-Schiff base resins, which integrates dual functions enhanced dynamic self-renewal photocatalytic antibacterial activities towards long-term anti-biofouling. The controllable complete degradability polymer chains mechanism DPC-x exposed internal g-C-NS, provided constant stream reactive interfaces for 100% release photocatalysts. g-C-NS were homogeneously dispersed coating, significantly enhancing adjusting rate visible light. degradation reaction DPC-0.2 (20 wt% g-C-NS) was 40 times that DPC, thus improving capabilities surface fouling-release. Due synergistic properties degradation/self-renewal, antimicrobial rates DPC 94.58% 99.31% dark, 98.2% 99.87% has excellent all-weather efficacy could offer new perspective eco-friendly strategies.
