Στην παρούσα διατριβή αναπτύχθηκαν και μελετήθηκαν κεραμo-μεταλλικοί ηλεκτροκαταλύτες/ηλεκτρόδια με βάση την εμπορικά διαθέσιμη σκόνη NiO/GDC (65 wt.% NiO – 35 wt.% Ce0.9Gd0.1O2-x). Η τελευταία τροποποιήθηκε με χημικές μεθόδους με σκοπό την προσθήκη FexOy, Au ή/και MoOx. Οι τροποποιημένοι ηλεκτροκαταλύτες χρησιμοποιήθηκαν σε μοναδιαίες κυψελίδες ηλεκτρόλυσης στερεού ηλεκτρολύτη (SOECs) ως ηλεκτρόδια καυσίμου (καθόδου). Σε όλες τις περιπτώσεις των υλικών πραγματοποιήθηκε φυσικοχημικός χαρακτηρισμός με διάφορες τεχνικές, καθώς και μελέτη της οξειδωτικής τους συμπεριφοράς παρουσία Η2Ο και CO2. Παράλληλα, από τις παραπάνω σκόνες παρασκευάστηκε κατάλληλη πάστα, η οποία εναποτέθηκε σε στερεούς ηλεκτρολύτες 8ΥSZ (ZrO2 σταθεροποιημένη με 8 mol% Y2O3) με τη μέθοδο εναπόθεσης με τελάρο (screen printing). Τα παραγόμενα ηλεκτρόδια Ni/GDC, 3 wt.% Αu-Ni/GDC, 3 wt.% Μο-Ni/GDC, 3 wt.% Au − 3wt.% Mo-Ni/GDC και 2 wt.% Fe-Ni/GDC μελετήθηκαν καταλυτικά, χωρίς την επιβολή ρεύματος, σε συνθήκες συν-ηλεκτρόλυσης Η2Ο/CO2 για την αντίστροφη αντίδραση μετατόπισης με ατμό (RWGS), στο θερμοκρασιακό εύρος 800-900 οC, με ανάλυση αερίων προϊόντων/αντιδρώντων. Ο ηλεκτροχημικός χαρακτηρισμός πραγματοποιήθηκε σε κυψελίδες SOECs, δύο ηλεκτροδίων, με ηλεκτρόδιο οξυγόνου τον εμπορικά διαθέσιμο περοβσκίτη LSCoF (La0.6Sr0.4Co0.8Fe0.2O3-δ) σε επαφή με στερεό ηλεκτρολύτη CeO2(Gd2O3)|ZrO2(8 mol% Y2O3). Μετρήσεις πυκνότητας ρεύματος-δυναμικού (i-V), ηλεκτροχημικής εμπέδησης (ΕΙS) και αέριας χρωματογραφίας (GC) συνδυάστηκαν, κατά περίπτωση, για τις διεργασίες ηλεκτρόλυσης του Η2Ο και συν-ηλεκτρόλυσης Η2Ο και CO2. Σκοπός ήταν η αξιολόγηση της ενεργότητας των τροποποιημένων ηλεκτροκαταλυτών και η μελέτη των παραπάνω ηλεκτροχημικών διεργασιών, στο θερμοκρασιακό εύρος 800-900 οC, για συγκεκριμένα μίγματα He-Η2Ο-Η2 και He-Η2Ο-CO2-Η2. Υποδεικνύεται άμεση συσχέτιση της δραστικότητας των δειγμάτων για την αντίδραση του Η2Ο με το Ni και της επακόλουθης οξείδωσής τους με την ηλεκτροχημική τους ενεργότητα. Το H2O, εκτός από το αντιδρών στη διεργασία ηλεκτρόλυσης, λειτουργεί ταυτόχρονα ως πιθανός παράγοντας απενεργοποίησης του Ni/GDC. Η τροποποίηση του Ni/GDC με 3 wt.% Au − 3 wt.% Mo ενίσχυσε την ανθεκτικότητα του ηλεκτροδίου στην οξείδωση από Η2Ο και βελτίωσε την ηλεκτροχημική του ενεργότητα. Ο επιφανειακός εμπλουτισμός με χρυσό, σε συνδυασμό με τον εμπλουτισμό της κύριας μάζας με μολυβδαίνιο, φαίνεται να οδηγεί σε ασθενέστερη αλληλεπίδραση των ροφημένων ειδών H2Oads με το ηλεκτρόδιο. Επίσης, ο σίδηρος αποδείχθηκε υποσχόμενος τροποποιητής του NiΟ/GDC έχοντας τη δυναμική να αντικαταστήσει ή/και να μειώσει τη φόρτιση σε χρυσό. Συγκεκριμένα, η τροποποίηση του Ni/GDC με 0.5 wt.% Fe βελτίωσε την ηλεκτροχημική του ενεργότητα. Από την άλλη πλευρά, η αλληλεπίδραση Ni και Fe, μέσω του σχηματισμού κράματος Ni-Fe, φαίνεται να ενισχύει το δεσμό ρόφησης του H2Ο επιταχύνοντας δυνητικά την υποβάθμιση του Ni/GDC σε κυψελίδες SOECs. Η μελέτη της RWGS αντίδρασης έδειξε ότι οι ηλεκτροκαταλύτες 2 wt.% Fe-Ni/GDC και 3 wt.% Mo-Ni/GDC παρουσίασαν τη βέλτιστη καταλυτική δραστικότητα για την παραγωγή CO. Η βελτιωμένη ενεργότητα των παραπάνω δειγμάτων συσχετίστηκε με την ισχυρότερη ρόφηση του CO2 και επακόλουθη δραστικότητα για την αντίδραση του CO2 με την τροποποιημένη επιφάνεια Ni. Ταυτόχρονα όμως, τα δείγματα αυτά ήταν και τα πιο επιρρεπή στην οξείδωση τόσο από το CO2 όσο και από το Η2Ο.Η μελέτη της ηλεκτροκαταλυτικής παραγωγής CΟ κατά τη συν-ηλεκτρόλυση Η2Ο/CO2 σε κυψελίδα Ni-GDC||YSZ||GDCbarrier|LSCoF έδειξε οτι η διεργασία αυτή εξαρτάται από τον λόγο pH2O/pCO2 και την pH2. Συγκεκριμένα, σε συνθήκες αντίδρασης όπου pΗ2Ο/pCO2 = 1 και pΗ2 = 21 kPa φαίνεται να λαμβάνει χώρα μόνο η ηλεκτρόλυση του Η2Ο και η επακόλουθη αύξηση της pΗ2 σε συνδυασμό με τη μείωση της pH2O μετατοπίζει την RWGS αντίδραση προς την καταλυτική παραγωγή CO. Από την άλλη μεριά, η ηλεκτροχημική αναγωγή του CO2 λαμβάνει χώρα σε συνθήκες αντίδρασης όπου pΗ2Ο/pCO2 < 1 και η έκταση αυτής της διεργασίας εξαρτάται σε μεγάλο βαθμό από την pΗ2. Σε συνθήκες όπου pH2O/pCO2 ≤ 0.3 και παρουσία χαμηλής pΗ2 = 2 kPa, η καταλυτική παραγωγή του CO περιορίζεται από την θερμοδυναμική ισορροπία της RWGS αντίδρασης και το παραγόμενο CO προέρχεται από την ηλεκτρόλυση του CO2. Η κυψελίδα κατά την ηλεκτροχημική αναγωγή του CO2 παρουσίασε υψηλότερες υπερτάσεις και σημαντικά υψηλότερες τιμές αντίστασης πόλωσης επιβεβαιώνοντας την ενεργειακή δυσκολία της συγκεκριμένης διεργασίας συγκριτικά με την ηλεκτρόλυση του Η2Ο.

In this study, we investigated whether electrolysis is a more effective method of hair removal in clients with polycystic ovary syndrome (PCOS) than laser hair removal. A total of 203 women with PCOS who completed a full course of electrolysis between 2021 and 2025 were examined. The study focused on hormonal sensitive facial areas ( chin, cheeks, upper lip, sideburns), were traditional light-based treatments usually fail. We compared clinical outcomes, safety, cost, and client satisfaction. Electrolysis has repeatedly shown superior efficacy for permanent hair removal, particularly in hormonally sensitive facial areas for all skin types. Laser hair removal in clients with polycystic ovary syndrome was reported to cause paradoxical hair growth (paradoxical hypertrichosis). Although electrolysis required more treatment sessions, it ultimately offered a more reliable, cost-effective, and permanent solution. Based on our findings, we prioritize electrolysis over laser hair removal when planning the treatment of facial hirsutism associated with polycystic ovary syndrome.

Breast cancer remains a significant global health concern, necessitating innovative approaches for its treatment. Using bacteria as vehicles for therapeutic delivery has emerged as a promising strategy. As a group of prokaryotic microorganisms, bacteria have great potential for use in cancer therapy. Thus, strategies for treating breast cancer need to be continuously refined to achieve a better patient outcome. This manuscript explores the potential of bacterial-based therapies for breast cancer treatment, elucidating the mechanisms underlying their application, safety considerations, and recent advancements. Nevertheless, notable challenges in bacterial-based cancer treatments include potential cytotoxicity, incomplete cancer cell lysis, and the risk of genomic mutations. With an emphasis on engineering bacteria to target and deliver therapeutic agents specifically to tumor sites, this manuscript provides insights into the future of personalized, precise, and effective breast cancer treatment.

Greywater is a wastewater discharge originating from kitchen sinks, showers, baths, washing machines and dishwashers. Properly treated greywater can be recycled to meet global water shortages that is expected to affect 2.7 billion people around the world by 2025. Global water shortage can result in a reduction in agricultural land and increased dissertation leading to poverty, faming, war, illegal migration and human trafficking. Greywater contains fewer pathogens than domestic wastewater, is generally safer to handle and easier to treat and reuse onsite for toilet flushing, landscape and crop irrigation. Recycling of grey water provides substantial benefits for both the water supply system by reducing the demand for fresh clean water, and for the wastewater system by reducing the amount of wastewater required to be conveyed and disposed of. In this paper, the existing biological treatment systems for greywater are reviewed. These are: (a) constructed wet land, (b) sequencing batch reactor, (c) vertical flow bioreactor, (d) membrane bioreactor, (e) up-flow anaerobic sludge blanket, (f) rotating biological contractors, (g) trickling filters, (h) aerated lagoons, (i) anaerobic up-flow filter, and (j) expanded bed up-floe reactor. In a biological treatment, the degradation and transformation of greywater constituents are facilitated by the biochemical reactions carried out by microorganisms in the liquid medium. However, the effluent of biologically treated greywater may contain pathogenic microorganisms, requiring a final disinfection step to eliminate the risk of contracting pathogenic diseases. Selection criteria for a disinfectant include: (a) non-toxicity to humans, domesticated animals, and aquatic ecosystems, (b) low cost (c) easy handling, (d) reliable analysis, and (e) a satisfactory residual concentration. Any disinfection process selected (whether chemical oxidants or irradiation treatment is selected) should be evaluated taken into consideration the conditions of the wastewater source and existing biological treatment design.

This method covers the determination of oily matter content of industrial waste water. Note 1.—The Joint Committee on Uniformity of Methods of Water Examination has concluded that uniformity of methods for the determination of grease and oily matter is not practical on the basis of present technical knowledge. Commonly used solvents are hexane, petroleum ether, benzene, chloroform, or carbon tetrachloride. These solvents exert selective extraction of specific greases and oily constituents. In addition, nonoily materials, such as phenolic type material and colloidal sulfur, are selectively extracted to varying degrees by these solvents. The selectivity of extraction is affected by the sample-to-solvent ratio. Oily matter and grease may be of mineral, animal, or vegetable origin. The solvent action exerted on material of such different chemical structure will vary to a marked degree. Thus application of a test method for oily matter or grease to such materials will necessarily produce a variety of results depending on the solvent used. In one case, a solvent may be an excellent extractant of mineral oil and a poor extractant of vegetable oil. In another case, a second solvent may be a poor extractant for mineral oil but excellent for extracting vegetable oil. The definition of grease and oily matter by necessity is based on the procedure used because of the above considerations. The source of the grease or oily matter, the solvent used, the sample-to-solvent ratio, the pH of the sample, and the inclusion of nonoily matter will dictate the material determined and influence the interpretation of the results obtained.

Symposium on Industrial Water and Industrial Waste Water • 1957

A study of a number of water or waste treating operations using the new organic flocculants and flocculation aids shows that these new materials are capable of increasing by as much as 100 per cent the capacity of water or waste treating equipment. In many instances the quality of the treated effluent can also be improved. Under some circumstances the use of these materials will allow a tenfold reduction in the total amount of treating chemicals to be fed. It is certain that as more operating experience is obtained using these polymers new equipment will be designed to take maximum advantage of the desirable properties they impart to the dispersed matter in water.

(a) This method covers the measurement of gamma radioactivity of industrial water and industrial waste water. It is applicable to gamma emitters in the energy range above 0.1 Mev and in the concentration range of 10−2to10−5 microcuries per milliliter of radioactively homogeneous water. (b) The method can be used for either absolute or relative determinations. In tracer work, the results may be expressed by comparison with an initial concentration which is taken as 100 per cent. For radioassay it may be expressed in terms of a known isotopic standard if the radionuclides concerned are known or it may be expressed arbitrarily in terms of some other standard such as cesium-137. General information on radioactivity and measurement of radiation has been published.

(a) This method covers the separation of chloroform-extractable matter from industrial water and industrial waste water, and the gravimetric determination of that portion of the extract which is not lost upon evaporation of the chloroform. This residue may contain one or more members of several classes of compounds, among which are heavy-oils and fats, trace amounts of phenols, rubber and certain resins, asphaltenes and carbenes, and decomposition products of tannin. (b) This method is applicable to the determination of heavy oils in industrial water and industrial waste water. It is not intended to determine materials that volatilize under the conditions of test nor to determine specific oils, greases, and organic compounds. When such information is desired, the residue obtained by this method may be subjected to further extraction with specific solvents agreed upon by the interested parties.

Industrial water always contains impurities consisting of substances present in the supply water or added, intentionally or unintentionally, during its use. The character and quantity of the impurities depend on the environmental and service conditions to which the water is exposed. Methods of analysis applicable to both industrial supply or process waters and to industrial waste waters are discussed in this chapter. The difference between the two types of waters is often only academic. In fact, waste water from one industrial process may become the supply water for another process. Industrial supply or process waters may contain higher concentrations of some constituents than some industrial waste waters. From the analytical standpoint, the same methods can often be used for both types of waters. Selection of constituents to be measured and methods of analysis for supply waters is based on the need for determining the suitability of the supply for a process use. Similarly, selection of constituents to be measured and the methods of analysis for waste water is based on determining the suitability of the water for reuse, disposal, or treatment prior to disposal.

The purification of water for industrial use can be very complex or relatively simple, depending upon the properties of the raw water and the degree of purity required. There are many methods and combinations in use, but all are covered in three basic processes: physical, chemical, and physicochemical treatment. A fourth basic process, biological treatment, is often employed where waste water must be purified before it may be discharged. This process takes advantage of the ability of living micro-organisms to induce a variety of chemical and physicochemical reactions. Treatment of waste water is usually a much more complicated operation than the production of process water of appropriate quality. This chapter discusses these processes as they are used in the treatment of industrial water and waste water and outlines some of the technical problems and basic considerations involved.

Membrane-bound heterotrimeric d-fructose dehydrogenase (FDH) from Gluconobacter japonicus exhibits distinct direct electron transfer (DET)-type bioelectrocatalytic activity. FDH contains three heme c moieties (heme 1c, 2c, and 3c), and the two downsized variants lacking heme 1c moiety (Δ1c FDH) or heme 1c and 2c moieties (Δ1c2c FDH) were constructed in our previous research. Recently, we elucidated the entire structure of FDH, enabling a structural perspective in mechanistic discussions. In this study, we quantitatively analyzed the downsizing effect of Δ1c- and Δ1c2c-deletion on DET-type bioelectrocatalysis. Non-catalytic redox signals of adsorbed enzymes were successfully obtained, providing a basis for independently evaluating kinetic parameters from DET-type catalytic waves. Analytical results revealed that the downsizing enhanced the electron transfer rate constant by 7-fold and 4-fold for Δ1c FDH and Δ1c2c FDH, respectively. Furthermore, the acceleration factors were discussed using structural predictions of the variants.

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.

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.

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].
