“…It is a kind of corrosion caused by microbes such as Acidithiobacillus thiooxidans, Thiobacillus thioparus, and Thiobacillus concretivorus. Some of the bacteria associated with microbiologically influenced corrosion (MIC) are sulphate reducing bacteria, iron-reducing bacteria and acid-producing bacteria [28,29]. Similarly, hydrogen sulphide causes hydrogen embrittlement or sulphide stress cracking in pipes.…”

New technologies are often sought to mitigate the problems associated with traditional drilling fluid formulations. Nanotechnology provides an alternative. A particle size of matter in the range of 1–100 nm in diameter (d.nm) is referred to as nanoparticle. Nanoparticles are broadly divided into various categories depending on their morphology, size and chemical properties. This size range lends their application in science and engineering. In rotary drilling operations where drilling fluid is at the center, performance and optimization issues have been observed. Use of polymer nanoparticles in mud formulations have been considered due to desirable properties such as wide specific surface area, high temperature stability and pollution resistance. Areas of application and advantages include improvement in mud rheology, fluid loss properties, improved lubricity, filter against hazard materials and cost effectiveness. Biodegradable polymeric nanoparticles possess the outlined properties and would continue to offer wider applications in drilling fluid technology now and in the nearest future due to their stable, film forming and gelatinization characteristics. To reliably estimate the quantity of polymeric nanoparticles to use, size and shape should be considered before concentration to apply to make prediction easier. Dispersion of different shapes, sizes and structures of polymeric nanoparticles might be a consideration to enhance polymer influence on fluid formulations.

Corrosion results from the electrochemical reactions between the metal and its existing environment. Corrosion results in severe and expensive damage to a wide spectrum of industries. When microbes are involved in corrosion it is seldom possible to economically evaluate its impact. Microbially influenced corrosion is recognized to cause catastrophic failures contributing to approximately 20% of the annual losses. In many engineering applications, microbially influenced corrosion control is of prime importance. Expensive, toxicity and sometimes, even ineffectiveness of the current chemical strategies to mitigate microbially influenced corrosion have shifted the interest towards eco-friendly inhibitors. The present review discusses microbial induced corrosion in various metals and its inhibition through eco-friendly inhibitors. In addition, the study also reviews the morphological and electrochemical impedance results.

“…The trend of change in peak power of each ceramic over the whole experimental period can be seen in Figure S3. Performance decrease in MFC power generation is common due to an increase of internal resistance as a result of increasing thickness of the anodic biofilm, bio-and abiotic fouling of porous materials including electrodes and separators, or microbially influenced corrosion [31][32][33]. Although fully hydrolysed urine was used in this study as a feedstock, a small degree of precipitation of uric salts was expected since neat urine was used without pre-treatment such as filtration.…”

A Comprehensive Study of Custom-Made Ceramic Separators for Microbial Fuel Cells: Towards “Living” Bricks

et al. 2019

Towards the commercialisation of microbial fuel cell (MFC) technology, well-performing, cost-effective, and sustainable separators are being developed. Ceramic is one of the promising materials for this purpose. In this study, ceramic separators made of three different clay types were tested to investigate the effect of ceramic material properties on their performance. The best-performing ceramic separators were white ceramic-based spotty membranes, which produced maximum power outputs of 717.7 ± 29.9 µW (white ceramic-based with brown spots, 71.8 W·m−3) and 715.3 ± 73.0 µW (white ceramic-based with red spots, 71.5 W·m−3). For single material ceramic types, red ceramic separator generated the highest power output of 670.5 ± 64. 8 µW (67.1 W·m−3). Porosity investigation revealed that white and red ceramics are more porous and have smaller pores compared to brown ceramic. Brown ceramic separators underperformed initially but seem more favourable for long-term operation due to bigger pores and thus less tendency of membrane fouling. This study presents ways to enhance the function of ceramic separators in MFCs such as the novel spotty design as well as fine-tuning of porosity and pore size.
