Steel corrosion is a global problem in marine engineering. Numerous inhibitory treatments have been applied to mitigate the degradation of metallic materials; however, they typically high cost and are not environmental friendly. Here, we present novel "green" approach for protection steel by bacterium Pseudoalteromonas lipolytica. This protects from seawater via formation biofilm followed an organic-inorganic hybrid film. The film composed multiple layers calcite bacterial extracellular...
The effect of single-layer graphene sheets (Gr) on the corrosion protection zinc-rich epoxy primers (ZRPs) was investigated. Scanning electron microscopy (SEM) with an energy dispersive spectrometer (EDS) were used to characterize morphology and composition coatings after immersion for 25 days. cross-sectional SEM images X-ray photoelectron spectroscopy (XPS) confirmed that addition facilitated assembling zinc oxides interface between coating steel. open circuit potential (OCP),...
Cutting fluid is a type of used in the metal-cutting process. It prone to microbial growth during use, which can lead deterioration its various useful properties; however, mechanism underlying this remains unclear. This study analyzed diversity field-sampled cutting fluids, and those with higher levels were inoculate other samples order further effects on properties fluids. The results show that surface sampled from tank machining tool contained predominantly aerobic bacteria, while bottom...
The marine bacterium, Vibrio natriegens, grows quickly in a environment and can significantly accelerate the corrosion of steel materials. Here, we present an approach to inhibit natriegens-induced by biomineralization. is mitigated seawater via formation biomineralization induced Bacillus subtilis. film composed extracellular polymeric substances calcite, exhibiting stable anti-corrosion activity. microbial diversity medium chemistry tests demonstrated that inhibition V. natriegens growth...
Bimetallic cost-effective CoNi nanoparticles (NPs) are conveniently supported on titanium carbides (MXene) by a simple one-step wet-chemical method. The synthesized CoNi/MXene catalysts characterized XPS, TEM, STEM-HAADF and ICP-AES. as-prepared NPs with size of 2.8 nm well dispersed the MXene surface. It is found that among bimetallic system, Co0.7Ni0.3 shows best performance toward catalyzing ammonia borane (AB) decomposition turnover frequency value 87.6 molH2 molcat -1 min-1 at 50 °C....
In desalination, a high level of calcium (Ca) and magnesium (Mg) ions in seawater can cause scale deposition on the reverse osmosis membranes water treatment systems. This process significantly affect efficiency desalination. addition, heavy metals human health. Therefore, Alcaligenes aquatilis from was used to remove Ca, Mg, nickel (Ni) by microbial-induced carbonate precipitation (MICP). The purification system then analyzed ionic analysis surface characterization. study shows that...
The adhesion of microorganisms and the subsequent formation mineralized layers in biofilms are great significance inhibiting corrosion metal materials. In this work, we found that mineralization
Abstract A new composite gel material was obtained by blending polyvinyl alcohol (PVA) aqueous solution with sodium alginate (SA), carboxymethyl cellulose (CMC‐Na), waterborne polyurethane (WPU), and polyvinylpyrrolidone (PVP). Titanium dioxide nanoparticles (nTiO 2 ) were doped as an antibacterial agent. The liquid could to form a transparent protective membrane. microstructure of the membrane observed via scanning electron microscopy, intermolecular interaction investigated total...
The corrosion mechanism involving bacterial biofilms has long been a focus of the research on microbiologically influenced corrosion. In this study, formed by Pseudoalteromonas marine and its mutant demonstrated ability to inhibit uniform However, excessive secretion colanic acid Δ01912 resulted in significantly increased number attached bacteria formation unevenly hydrophilic biofilms, which aggravated localized pitting steel surface. This study provides evidence that can lead local...
