Nitrogenase is the only enzyme capable of nitrogen reduction to ammonia. This talk will discuss cobaltocene and methyl viologen mediation schemes for MoFe and VFe nitrogenase, as well as strategies for nitrogenase bioelectrocatalysis in air. Bioelectrocatalysis of proton reduction, azide reduction, nitrite reduction, nitrogen reduction, and carbon dioxide reduction by MoFe and VFe nitrogenase will be shown. These preliminary data showed the many applications of nitrogenase bioelectrocatalysis, but to be technologically useful, direct bioelectrocatalysis is needed. This talk will discuss the design and synthesis of a pyrene modified linear polyethylenimine and its use for MoFe, VFe and FeFe nitrogenase bioelectrocatalysis. This direct bioelectrocatalysis has allowed us to mechanistically study nitrogenases in more detail.

Проведено измерение биоэлектрических потенциалов, генерируемых в корнеобитаемой среде в процессе развития растений салата сортов Тайфун, Вишневая дымка и Гранатовые кружева, различающихся по эффективности работы фотосинтетического аппарата. Для исследования влияния спектрального состава излучения на электрогенные свойства системы корнеобитаемая среда-растения были использованы источники света, моделирующие естественное освещение в различное время суток. Различия в интенсивности фотосинтетических процессов оценивались по индексам диффузного отражения листовой пластинки, интенсивности пропускания света листьями и параметрам флуоресценции. Из исследованных сортов салата наилучшими электрическими характеристиками обладал сорт Гранатовые кружева – среднее значение разности потенциалов для него составило 417±60 мВ при освещении источником света AFI-5000 со спектром, близким к солнечному свету в полдень, и большей составляющей синей области из изученных вариантов. Ключевые слова: биоэлектрохимическая система, спектр излучения, пропускание света, флуоресценция, индексы отражения. The bioelectric potentials generated in the root environment during the development of lettuce varieties Tayfun, Vishnevaya dymka and Granatovyye kruzheva, which differ in the efficiency of the photosynthetic apparatus, were measured. To study the influence of the radiation spectral composition on the electrogenic properties of the root environment-plants system, light sources that simulate natural illumination at different times of the day were used. Differences in the intensity of photosynthetic processes were assessed by the diffuse reflectance indices, intensity of light transmission and fluorescence parameters of leaves. Lettuce variety Granatovyye kruzheva had the best electrical characteristics among the studied varieties – the average value of the potential difference for it was 417±60 mV when illuminated by an AFI-5000 light source with a spectrum close to sunlight at noon, and the largest component of the blue region among the studied options.

Abstract This paper presents the design and control of a novel full active powered ankle prosthesis driven by electro-hydrostatic actuator (EHA) to improve amputee gait during the level-ground walking in full-time gait cycle. A 100W brushless DC motor driving a 0.92 cc/rev bi-directional gear pump serves as the power kernel. An elastic element is configured in series with the hydraulic cylinder. With this architecture, better power characteristic, ability of energy storage and passive compliance are obtained to revive sound human characteristic as much as possible. To smooth the gait pattern, a neuromuscular model with Hill-type muscle tendon structure is introduced into the control system scheduled by finite state machine which was designed to carry on different control strategy during individual gait phase.

Recent research indicates that paranormal belief, in the absence of allied cognitive-perceptual and psychopathology-related factors, is not associated with negative wellbeing outcomes. However, investigators have historically reported relationships between specific facets of belief (e.g., superstition) and stress vulnerability. These typically derive from the Revised Paranormal Belief Scale (RPBS), which has questionable psychometric integrity. The main issue being that several RPBS items perform poorly. Noting this, the present paper re-examined the relationship between paranormal belief and stress using the Rasch purified version of the RPBS. This comprises two dimensions, called Traditional Paranormal Belief (TPB) and New Age Philosophy (NAP). These are operationalised in terms of function. Specifically, whether belief provides a sense of control at the social (TPB) or individual level (NAP). Accordingly, this study examined whether TPB and NAP were differentially predictive of levels of perceived stress. In this context, stress served as an indicator of well-being. A sample of 3084 participants ( M age = 50.31, SD = 15.20, range 18–91) completed the RPBS alongside the 10-item Perceived Stress Scale (PSS-10). Confirmatory factor analysis and structural equation modelling revealed that TPB was significantly predictive of higher Distress, and lower Coping. NAP was neither predictive of Distress nor Coping. These findings support the notion that TPB is attendant with external control, particularly the notion that unknown supernatural forces/powers influence existence.

Fundamentals of Electrochemical Corrosion · 2000
Abstract This chapter familiarizes readers with the basic concepts of corrosion, discussing chemical reactions, ion transfer mechanisms, electrochemical processes and variables, and the formation of solid corrosion products. It presents a simple but effective teaching tool, the elementary electrochemical corrosion circuit, using it to explain how electric potential differences drive the corrosion process and how corrosion rates vary in proportion to current density. The chapter concludes with a discussion on the importance of corrosion products, such as oxides and hydroxides, and how their formation can be a major factor in controlling corrosion.
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.
