Fundamentals of Electrochemical Corrosion • 2000
Abstract This chapter discusses the principles and procedures of electrochemical measurements used to investigate corrosion behaviors. It begins by presenting a diagram of a basic potentiostatic circuit, which consists of a working electrode and an auxiliary or counter electrode suspended in an electrolytic solution. It describes how corrosion potentials and current densities are measured and explains how to deal with various sources of error. It also explains how electrochemical impedance measurements are used and describes the underlying theory and procedures in some detail.

There is a widely held view that Britain's poor performance in exports and economic growth can be attributed to relatively old-fashioned techniques of production—a handicap which might be particularly important in industries where technological progress is rapid. The only way to establish whether this view is right or not is by empirical investigation. Unfortunately such investigation is difficult, because not many industries have adequate statistics.

It is now accepted that the human microbiome plays a key role in human health, and disturbances in the microbiome can cause or aggravate a range of diseases, from metabolic to immune disorders and mood disorders [1]. In addition, microbiota imbalance or dysbiosis may arise due to careless use of antibiotics in humans and animals, leading to the emergence of antibiotic-resistant bacteria that may compromise the effectiveness of antibiotics, so there is an urgent need to identify and develop new strategies to combat antibiotics resistance [2,3]. So far, probiotics are considered as perspective alternatives to antibiotics [4]. Probiotics are defined by the FAO/WHO as “Live microorganisms which when administered in adequate amounts confer a health benefit on the host” and they are successfully used for preservation of the microbial community [5].Moreover, bacteriocin-producing commensal microbes have the capacity to eliminate specific colonizing pathogens from various human body sites, and, as many bacteriocins have only narrow activity ranges they can be used for precision therapy and infections prevention [6]. Lactic acid bacteria, particularly lactobacilli, are the best known probiotics that modulate the immune system, and produce significant amounts of bioactive compounds, including bacteriocins, to eliminate pathogens and limit the clinical effects of antibiotic use [7, 8].

The Paint Research Association reports that despite the good hygiene practised in most paint factories microbial contamination occasionally occurs. This can cause thinning, gassing or malodour in aqueous paints rendering them unsaleable. The cost of paint raw materials is rising faster than the general rate of inflation and the cost of a spoilt batch is a serious matter for paintmakers.

Electric Vehicles, especially electric vehicles with bidirectional Vehicle-to-Grid (V2G) connectivity, can serve as electric energy storage assets. Following the dramatic increase in electric vehicle registrations in 2022 there can be little doubt that electric vehicles will become a major portion of the entire light duty personal transportation fleet. This paper endeavours to project the growing electric energy storage capability of this asset. It shows that the storage available from the EV fleet may grow to match the daily output of projected solar PV generation in the 2025-30 time period, and greatly exceed the requirements of the EV fleet itself. This presents the possibility of a massive renewable generation capability, levelled and controlled by an even more massive electric vehicle fleet energy storage capability which can offset its intermittent and uncontrolled nature, as a future zero emission energy grid.

In this work, the percentage of removal of organic matter and phosphates from municipal wastewater of the Wastewater Treatment Plant (WWTP) Puca Puca, Ayacucho Region, Peru was determined by applying the combined method of photochemical water treatment and biological, which consists of coupling the photolysis process and the microalgae culture technique using Chlorella sp. The experience was carried out at the laboratory level using a photoreactor with an ultraviolet (UV) lamp for the photolysis process and a set of bioreactors that were illuminated with a light emitting diode (LED) lamp and continuously injected with CO2 from the air and a pure gas system during the biological process. Finally, with the application of the integrated photochemical and biological method, it was possible to reduce the organic matter of the municipal wastewater of the Puca Puca WWTP from 226 to 102.6 mg/L (54.60%) and from 93 to 55.17 mg/L (40.68%) for chemical and biochemical oxygen demand respectively; and phosphates from 6.8 to 4.1 mg/L (33.82%). A similar performance was observed in the cultivation of microalgae with wastewater without prior treatment with Photolysis. In this case, the decrease in chemical and biochemical oxygen demand was from 226 to 90.9 mg/L (59.78%) and from 93 to 48.78 mg/L (47.55%) respectively, and phosphates from 6.8 to 4 mg/L (41.18%).

Climate change is altering the planet and threatens humanity. Earth system models simulate the planet's physical, chemical, and biological processes to help scientists understand current environmental changes and make projections for Earth's future, which can inform society's responses to combat and mitigate climate change's negative effects. Climate change will fundamentally change life on Earth, including microorganisms. Microbes will also influence climate change by driving biogeochemical cycles through the consumption and production of greenhouse gasses. Thus, explicitly including microbial processes into Earth system models can improve model projections. However, fully understanding the feedbacks between climate change and microbes, and then including those processes into Earth systems models, is a major challenge. This report is based on the deliberations of experts who participated in a virtual colloquium on 6 and 8 December, 2022, organized by the American Academy of Microbiology, which is the honorific leadership group and think tank within the American Society for Microbiology. At the colloquium, these experts from the climate and microbial sciences attempted to clearly articulate current knowledge gaps of the two fields. As a result, the participants compiled a list of top ten challenges to better incorporate microbial processes into Earth system models. Solving these challenges requires new thinking and approaches. Transdisciplinary efforts have the potential to propel science—and society—towards combating climate change.

Waste biomass is a cheap and relatively abundant source of electrons for microbes capable of producing electrical current outside the cell. Rapidly developing microbial electrochemical technologies, such as microbial fuel cells, are part of a diverse platform of future sustainable energy and chemical production technologies. We review the key advances that will enable the use of exoelectrogenic microorganisms to generate biofuels, hydrogen gas, methane, and other valuable inorganic and organic chemicals. Moreover, we examine the key challenges for implementing these systems and compare them to similar renewable energy technologies. Although commercial development is already underway in several different applications, ranging from wastewater treatment to industrial chemical production, further research is needed regarding efficiency, scalability, system lifetimes, and reliability.

This review explores electron transfer kinetics from an electron donor to the anode in electrically conductive biofilm anodes. Intracellular electron transfer (IET) from the donor to the anode is well described with the Monod equation. In comparison, mechanisms of extracellular electron transfer (EET) conduction are unclear yet, complicating EET kinetics. However, in biofilm anodes where potential gradient to saturated current density is less than ∼300 mV, Ohmic conduction successfully describe conductive EET mainly with biofilm conductivity (K bio ) and biofilm thickness (L f ). High K bio essential for production of high current density is found in Geobacter pure or enriched biofilm anodes, but other exoelectrogens could make biofilms electrically conductive. IET is rate-limiting for current density in conductive biofilms, and biofilm density of active exoelectrogens and L f are operating parameters that can be optimized further to improve current density.

Purpose Derelict fishing gear (DFG) is one of the most abundant and harmful types of marine litter that gets increasingly retrieved from the ocean. However, for this novel waste stream recycling and recovery pathways are not yet commonly established. To identify the most suitable waste management system, this study assesses the potential environmental impacts of DFG waste treatment options in Europe. Methods This study applies an attributional life cycle assessment (LCA) to four DFG waste treatment scenarios, namely a mechanical recycling, syngas production, energy recovery and landfill disposal. The scope spans from the retrieval and transport processes to pre- and end-treatment steps until the outputs are sent to landfill or assumed to substitute products or energy. Primary data was collected from retrieval and waste treatment trials in Europe. Contribution, sensitivity and uncertainty analyses were conducted using the LCA software SimaPro and ReCiPe as the impact methodology. Results and discussion The results show that the mechanical recycling and energy recovery achieve the lowest potential environmental impacts. The syngas production and landfill disposal scenario are not environmentally competitive because they require too much electricity, or their avoided production credits were too small to offset their emissions. Unlike the pre-treatment and transport processes, the retrieval and end-treatment processes have a significant impact on the overall results. The transport distances, energy mix and market and technological assumptions are least sensitive, while changes to the waste composition significantly affect the results. Especially a reduced lead content benefits the human toxicity impact potential of the landfill disposal scenario. The uncertainty analysis showed that the results are very robust in nine of twelve impact categories. Conclusions This is the first LCA study that compares waste treatment options for marine litter. The results indicate that a disposal of DFG is hazardous and should be replaced with mechanical recycling or energy recovery. While this may be technologically possible and environmentally beneficial, economic and social factors should also be considered before a final decision is made. To further reduce environmental impacts, marine litter prevention should play a more important role. Graphical abstract

Aluminium industry emits around 1–2% of the world’s total greenhouse gas emissions. Up to one-third of those are linked to the thermal energy consumed during its initial process: the alumina refining (Bayer process). Previous studies consider the Bayer process a single stage despite its being made of several reaction stages. This work presents a disaggregated energy analysis of the Bayer process that facilitates to find relationships between the main variables in regular alumina production and the environmental impacts. Two different thermodynamic simulations of the Bayer process were carried out using Aspen V11 software. The results of these simulations were validated with referenced data, and afterwards, they were used to perform a life cycle assessment. ISO 14040 and 14,044 standards were followed during the analysis. LCA was implemented on SimaPro 9.0, and ReCiPe 2016 Midpoint (H) method was used to calculate environmental impacts. The influence of bauxite mineral form, type of fuel (energy input), and the distance from the mine to the plant was analysed throughout the study. As expected, the type of fuel was revealed as the most crucial factor in the environmental impact of alumina production, with potential savings of up to 75.5% of CO2-equivalent emissions. Nonetheless, the tendency is diverse for other indicators, such as marine eutrophication or terrestrial acidification. On the other hand, while bauxite transportation always has the same impact on the different environmental indicators, bauxite mineral form affects differently depending on the fuel, causing variations in the CO2-eq emissions from 7.7 to 51.3%. Results indicated that the electrification of heat-demanding processes and the use of renewable power is the most effective approach for reducing environmental impacts. This strategy, however, must be considered in combination with others, as interdependent effects exist on the type of mineral used. These results provide strong evidence of the potential for environmentally friendly strategies in the metal industry, including new processes, alternative fuels, or mineral switching to promote more sustainable aluminium production.
