Narrativization of news video content during the period of martial law
(using the example of «Suspilne Sumy»)
Authors: Rodyhin Kostiantyn
Published: February 2023

Introduction. The propagandistic basis of the Russian war against Ukraine includes the narrative about so-called «Ukrainian nationalists» as an «enemy image» firmly identified with «fascists» or «Nazis». This is likely a revival of Soviet propaganda inventions, so, a study of constructing a «Ukrainian nationalist» image in Soviet propaganda gains relevance. This article continues the study of this image in cartoons of Soviet Ukrainian satiric magazine «Perets’» («The Pepper») in 1941–1991.
The article aims to develop the coverage of the topic of propagandistic typification of the «Ukrainian nationalist» visual image as an «enemy image» in terms of its contexts and personalities in «Perets’» cartoons.
Methodology. The methodology continues the principles of our earlier work. The methods of research include observation, content analysis, generalization, comparison, quantification, and data visualization.
Results. The most common companions of the «Ukrainian nationalist» character in the «Perets’» Soviet-era cartoons are 1) «American imperialists», 2) Nazis, 3) counterrevolutionaries, and 4) Zionists. If the first two categories were represented steadily for decades, as the versions of «the main enemy», then the third had been slowly decreasing, and the fourth one – on the contrary, sharply gaining popularity in the 1970s. The motif of «brotherhood of Zionists and Ukrainian nationalists» appears as a prototype of some concepts in the present-day Russian-Ukrainian semantic war.
The modern Russian narrative about «Ukrainian nationalists» identifying them with the Nazis and the Americans at the same time, revives the old developments of Soviet propaganda. The results of the study of cartoons in terms of the representation of personalities are somewhat unexpected: in particular, the image of Stepan Bandera turned out to be less common than it was expected in view of his role in present-day Russian war narratives. Personified images of «Ukrainian nationalists» do not make up the vast majority of the materials in question. However, they provide interesting information about which persons and with what priorities attention was paid during the satirical and ideological processing of «enemy images».
Conclusions. The significance of the article lies in the further consideration of an insufficiently researched topic using a quantitative approach. Promising areas of further research are the discovery of the methods of associating some «enemy images» with the «fascist/Nazi» image in Soviet and modern Russian propaganda; study of the novel ideological myths and their representation
in the media; retrospective study of the genesis of propagandistic mythologems of the Russian-Ukrainian war.
Fertilization and Paclobutrazol Application for Sustainable Production and Post-production Performance of Petunia
Authors: Park Jiwoo , Faust James E.
Published: February 2023

This study examined the interaction between constant liquid fertilization (CLF) concentrations and plant growth regulator (PGR) application concentrations on petunia (Petunia ×hybrida) growth and flowering in the production and post-production environments. Paclobutrazol application is a common practice in bedding plant production to achieve a compact plant that increases greenhouse space-use efficiency, shipping density, and tolerance to physical handling stresses in the post-production environment. The objective of this research was to determine the best strategy for balancing CLF and PGR application concentration in the greenhouse environment so that growth and flowering can be maximized in the post-production environment. A two-factorial combination of four CLF concentrations [50, 100, 150, or 200 ppm nitrogen (N)] and four paclobutrazol drench concentrations (0, 5, 10, or 20 ppm) were provided to plants during the production phase, and plant growth and flowering were recorded in the production and post-production environments. From a sustainability perspective, the ideal PGR concentration was 5 ppm paclobutrazol, since this concentration resulted in the best combination of production and post-production characteristics and performance. At this PGR concentration, all plant growth and flowering measures increased as CLF increased from 50 to 200 ppm N; however, all CLF concentrations also produced commercially acceptable plants. Therefore, the ideal CLF concentration depends on the size of plant desired; that is, CLF concentrations as low as 50 to 100 ppm N can be provided depending on the market size requirements of the plants being grown. Based on our results, a combination of 50 ppm N CLF with 0 ppm paclobutrazol or 100 ppm N CLF with 5 ppm paclobutrazol both demonstrated adequate growth control during both production and post-production phases.

Multi-dimensional dynamic spatio-temporal evolution of the green development efficiency of water-energy-food in China
Authors: Li Jinqiu , Huang Dechun
Published: February 2023

This paper constructs a green development efficiency index framework of water-energy-food in China, and uses the Super-EBM model to measure it more accurately and scientifically. The existing studies on water-energy-food efficiency lack the analysis of regional differential decomposition and spatial state transition. In this paper, two kinds of models are used for complementary analysis. One is kernel density map, Dagum spatial Gini coefficient decomposition and traditional Markov chain, which does not contain spatial factors. The other is the global Moran index, spatial Markov chain and spatial spillover effect, including spatial factors. The spatio-temporal dynamic evolution of the green development efficiency of water-energy-food (GWEF) in China is compared from the perspective of national, regional and provincial dimensions. The conclusion is more scientific and comprehensive, which is conducive to the green collaborative development among water-energy-food, economy and environment in China. The study found that GWEF had a lot of room for improvement. The overall spatial difference was mainly derived from the regional difference. GWEF had a significant positive spatial autocorrelation. The development of GWEF maintained the convergence characteristics of clubs. The spatial spillover effect of the main influencing factors was studied.
Jezus spłonął w stodole. Obraz chrześcijan w "Pingpongiście" Józefa Hena
Authors: Żurek Sławomir Jacek
Published: February 2023

The article, consisting of four parts, examines Józef Hen’s novel Pingponista (The Ping-Pong player) as an example of “post-Jedwabne literary discourse” (Marta Tomczok). The first part is a short presentation of the history of the Roman Catholic Church’s teaching on Jews and Judaism, in which one can find anti-Judaic and anti-Semitic elements being presented for centuries by Church authorities. This situation was changed by the Second Vatican Council’s (1962–1965) declaration in Nostra aetate. Declaration on the Relation of the Church to Non-Christian Religions (p. 4). Nonetheless, the Church’s teaching of contempt toward the Jews had been influencing Christian thinking for a very long time. The second part of the article is a study of the main protagonists of Hen’s novel, who include both Poles and Jews. All of them visit a small Polish town (Cheremec) to commemorate the victims of an anti-Jewish pogrom in 1941. In the third part, observations are made about the different Christian attitudes toward Jews represented by the protagonists in The Ping-Pong Player. Only a minority of the Polish people in Cheremec took part directly in the pogrom, while a minority of them, in turn, defended the Jews. The majority of the town’s inhabitants were neutral and passive. The author ponders the reasons for this situation and considers it in the context of the town’s contemporary Polish population. He looks for connections between anti-Semitism and antiJudaism and the axiologies guiding everyday Christians. According to him, Polish Catholics do not connect the events of the Holocaust to the history of religious teaching in the Magisterium of the Church and do not see in the murdered Jews the “chosen people” – the same ones they hear about on Sundays in readings from the Bible in Church. They do not understand that their Christian God – Jesus Christ – was (and is) also a Jew, a member of this persecuted people. The title of the article is taken directly from the novel, where the parish priest of the Catholic parish in Cheremec (Father Ziemowit) says that “Jesus burnt in the stable”, together with the Jewish inhabitants of the town. The fourth part of the article is an axiological analysis of the novel in the context of Christian-Jewish relationships and literary studies on recent Polish narratives of the Holocaust.
Dziennik jako forma życia. Zapiski Józefa Hena. Genezy, genealogie, archiwa
Authors: Dąbrowski Bartosz
Published: February 2023

The article discusses the impact of the experience of the Holocaust and the war on the form and issues of eight volumes of Józef Hen’s literary journals I am not Afraid of Sleepless Nights. The “long shadow” of these traumatic events shaped both the history of their delayed origins, the form of the notes, and their main themes. The poetics of these diaries is based on the structure of a collage, which, on the one hand, connects the past and present, and on the other, it combines the chronicle of everyday life with night-time meditations, memories and reflections on history, wartime and post-war experiences and the Jewish fate. Hen contrasts these devastating forces of the twentieth century with his own philosophy of life, which is a special form of Jewish vitalism. The diary thus becomes a symbolic form of survival in the form of a literary, autobiographical work. All the volumes of Hen’s journals seem to be permeated by the effort to record, preserve and perpetuate what is characterized by the fragility and susceptibility to the corrosion of time – that is, life itself. Ultimately, thanks to this effort, the trace of the author’s own presence is also preserved. The collage poetics of the record, resulting from “composing”, makes it part of the work itself. The subject is transformed in it into an idiomatic “gesture”, i.e., a trace of a constantly repeated expressive act, which seems to retain traces of the author’s expressive gestures, his preferences, choices and ways of seeing, and the modality of individual feeling recreated in the text. In a way, it can be said that, according to Hen, journals are written to preserve the specific literary composition of existence. A diary understood as a “form of life” preserves a certain inalienable ethical moment, contained both in the need to give a certain order to the biography and to save the life experience itself – in its various forms. While history and everyday life constitute a source of a constantly reborn fear in Hen’s diaries, as they seem to still emerge in the long shadow of the Holocaust and the possibility of its possible repetition recognized in many events, the very ability to transform them into a diaristic record counteracts it therapeutically. For despite the fact that life can be destroyed, thanks to writing – as Hen’s final lesson seems to sound – something can always remain and survive.
Wypełnić puste miejsca. O fascynacjach literackich i praktykach adaptacyjnych Federica Felliniego
Authors: Kletowski Piotr
Published: February 2023

The main aim of this essay is to show the original adaptive technique used by Federico Fellini in his films, which were based on literature. Although Fellini was inspired by many literary works in his work, he adapted only four text directly. These are: Edgar Alan Poe’s novella Don’t Bet with the Devil on the Head, brought to the screen as Toby Dammit – a segment of the horror novella Three Steps into Madness (Histoires extraordinaires, 1968); Satyrics of Petronius (Fellini – Satiricon, 1969); The story of my life by Giacomo Casanova (film: Il Casanova di Federico Fellini, 1976) and Poem of Sleepwalkers (Poema di lunatici) by Ermano Cavazzoni, which are the basis of the director’s last work, the film The Voice of the Moon (La voce della luna, 1990). In the works transferred to the screen, the Italian director was looking not so much for material to create a faithful, cinematic version of the work, but he was looking for empty spaces that he could fill with images created in his own imagination (although in his own way consistent with what the authors of the literary prototypes had created). Thanks to this, Fellini’s film adaptations of literature are more projections of his artistic talent than the visions of the original creators of the book’s prototypes.
Polański, Hitchcock i MacGuffin
Authors: Pawłowska-Jądrzyk Brygida
Published: February 2023

The main subject of the article is the relationship between the creative method of Roman Polanski and Alfred Hitchcock and the attitude of the Polish director to genre cinema. The author of the text, critically analyzing the earlier diagnoses of Polish monographers of Polanski’s work (Grażyna Stachówna, Mariola Dopartowa), prove that these problems are difficult to reduce to the MacGuffin issue today, because they “loop” at many levels and in various interpretative concepts, consistently eluding easy generalizations.
Polish Modernization in Biographical Films of the 2010s
Authors: Mazierska Ewa Hanna
Published: February 2023

This article examines representation of the state socialist past in three Polish biographical films, made in the 2010s, Bogowie (Gods, 2014), directed by Łukasz Palkowski, Sztuka kochania (The Art of Loving, 2017), directed by Maria Sadowska and Ostatnia rodzina (The Last Family, 2017), directed by Jan P. Matuszyński. It argues that it them Poland is represented as a country trying to modernize itself and investigates how this modernization is achieved. It does so by locating these films in two contexts: the discourse of Poland’s modernization and biographical film.

By analyzing the biographies of selected women jewelers who trained in the 1930s, the career paths available at that time were indicated. The article also tries to answer the question of how the conditions in which the jewelry industry in Poland operated at that time influenced the situation of women entering the profession. It can serve as a reference point for further research on the presence of women in jewelry in Poland and Central and Eastern Europe.
The Challenges and Hopes of the Korean Catholic Church towards Synodal Church: A Religious Sociological Approach
Authors:   The Society of Theology and Thought, Kim Seon Pil
Published: February 2023

This paper examined the challenges of the Korean Catholic Church and the seeds of hope that the Holy Spirit sowed in the Church. Before the Universal Church summoned Synodalitas, the Korean Church had tried to fol-low the image of the Early Church, which is a model of the Synodal Church. Nevertheless, the emphasis on Synodalitas in the Korean Church to-day reminds us that the Korean Church is still on a journey toward renewal, and that there are many challenges that block the way to the Synod church. In fact, there is a conflict between priests and faithfuls in the Korean Church, and there is an atmosphere of leaving the Church or looking at each other indifferently because they cannot find joy in their religious life. In ad-dition, the rapid aging phenomenon is bringing unexpected problems in the Church, and the male-centered system is causing another conflict of gender inequality.
Of course, there are not difficulties only. Priests devoted to believers, and believers who obey the Divine authority of priests, the Church that approach members, and the Church that try to be with the underprivileged in the soci-ety are all seeds of hope sown by the Holy Spirit so that the Korean Church can move toward the Synod church. These seeds may look small now, but they will soon become big trees that support the Korean Church “just as mustard seeds grow into big trees.”
Nano Emulsion Drug Delivery System: A Review
Authors: Mishra Nitin , Kaushik Niranjan , Sharma Pramod Kumar , Alam Md. Aftab
Published: February 2023

In nanoemulsions, both oil and water droplets are stabilised by an amphiphilic surfactant. Ultrafine dispersions with varying drug loading, viscoelastic properties, and aesthetic characteristics may be useful for the administration of medication. A 20-500-nanometer droplet size range for nanoemulsions has been established. The biological behavior of a nanoemulsions formulation is heavily influenced by its droplet diameter and surface properties. Small droplet size results in clear emulsions; therefore, the appearance of the product is unaffected even by the addition of an oil phase. Nanoemulsions are oil-in-water dispersions that are transparent or translucent and are stabi-lized by an interfacial layer of surfactants and cosurfactant particles with droplet size smaller than 100 nm. New nanoscience-based technologies are becoming increasingly popular as a means of im-proving food safety, quality, and nutrition. In this field, nanoemulsions have been a key focus since they can be readily manufactured using current food components and technology. Food nanoemul-sions, which are tiny oil droplets distributed in water, are being used as delivery methods for a vari-ety of hydrophobic compounds, including nutrients, nutraceuticals, antioxidants, and antimicrobial agents. The present review is focused on the formulation, characterization, and applications of nanoemulsions.
The Incipit Miniature of the Morgan Gospel of John
Authors: Baert Barbara
Published: February 2023

In this paper, I explore the iconographical relationship between the letters and the support on fol. 157r of the Morgan Gospels, written and illuminated in Westphalia, Germany during the mid-tenth century. On the basis of its formal properties and the iconographic meaning it takes, I will give particular attention to the materiality of the Latin text and its cultural and symbolic significance. The folio under study develops a form of  ‘agency’. With this perspective, I hope not only to contribute to the important line of argument Joshua O’Driscoll develops in his iconic article, but also to explore the meaning of Latin as an iconological statement and hence to contribute with new methodological developments in the field of art history.

On Two-Frequency Oscillations of a DC Electric Drive with Pulse Control
Authors: Yanochkina O. O.
Published: February 2023

Purpose of research is of the paper is to analyze bifurcations of two-frequency oscillations of a DC electric drive with pulse-width control.Methods. The research is based on the construction of a stroboscopic Poincare map, the calculation of saddle periodic orbits and their stable and unstable invariant manifolds.Results. The study of the mechanisms of the occurrence of two-frequency oscillations from a periodic motion that loses stability in a DC electric drive with pulse-width control was carried out. A non-local saddle-node bifurcation leading to resonance (synchronization) on a torus characterized by a pair of independent frequencies when their ratio becomes a rational number, was studied.Conclusion. A bifurcation analysis of the control system of a DC electric drive, the dynamics of which is described by non-smooth nonautonomous differential equations, was carried out. The research was conducted on an iterable map obtained from the specified vector field in an analytical form. It is shown that the system under consideration demonstrates two-frequency oscillations that occur through the Neimark-Sacker bifurcation. In the phase space of the discrete model, a closed invariant curve corresponds to oscillations with two independent frequencies. It is shown that if these frequencies are correlated multiply, then a resonance occurs when the dynamics becomes periodic. But at the same time, the closed curve remains invariant, and the limit points of the orbit form a pair of periodic cycles – stable and saddle, corresponding to a rational frequency ratio. A closed invariant curve is formed by unstable manifolds of a saddle cycle. If the frequency ratio is irrational, then the dynamics is quasi-periodic. The orbits of such motion fill the closed curve everywhere densely.

The Relationship between Rem Sleep Behaviour Disorder and Parkinson’s Disease Revisited – Are They One and the Same?
Authors: Beran Roy G
Published: February 2023

This paper reviews the relationship between RBD and PD and the pathophysiology. Most RBD patients develop PD within 14 years. PD pathophysiology is α-synucleinopathy with dopamine degeneration in nigrostriatal pathways. RBD pathology is poorly understood. Anomalies suggest RBD and PD are different, evidenced by smoking. RBD and PD are associated with glucocerebrosidase gene mutations (GBA gene), suggesting RDB with GBA gene mutation predicts PD. PET imaging, assessing vesicular monoamine transporter 2 (VMAT2), indexing nigrostriatal dopamine innervation, is lower in PD and RBD, in the putamen, ventral striatum and globus pallidus but not substantia nigra or subthalamus, compared with controls. VMAT2 may not contribute to pathophysiology of RBD in PD. Treatments for RBD and PD differ. PD with RBD had more depression, compared to PD without RBD. Only PD with RBD had statistically significant increased depression, compared with controls, and non-significant lowered cognition. PD patients, with and without RBD, had decreased ligand binding, compared to healthy controls, indicating no difference in VMAT2 within the caudate and putamen. Research showed differences in cholinergic levels, noradrenaline and glucose metabolism for PD with and without RBD. RBD with PD, is multi-systematic, affecting regions beyond dopaminergic pathways. Treatment of RBD does not affects PD neurodegeneration. Researchers continue to search for neuro-protective intervention. There is a relationship between PD and RBD but it is not absolute. PD nigrostriatal degeneration is independent of RBD. Pathophysiological differences may explain why treatment of RBD does not alter its natural history.

The purpose of this qualitative study was (1) to explore patients’ experiences and perspectives with the adoption and use of virtual care during COVID-19 in Newfoundland and Labrador, Canada, and (2) identify the education and informational needs of patients to inform future strategies for supporting patient use of virtual care.

Methods

Using a phenomenological approach, we conducted a focus group interview with a purposive sample of patient representatives representing a cross-section of the population of the province of Newfoundland and Labrador. Five patient representatives were recruited from the Newfoundland and Labrador Support Patient Advisory Council and participated in the focus group. The focus group was conducted in February 2022 via videoconferencing technology. Using thematic analysis, we identified several recurrent themes that described respondents’ experiences with the use of virtual care during COVID-19, as well as their perceptions of education and informational needs to support more effective patient use of virtual care.

Results

Respondents felt that virtual care is a beneficial addition to the health care system, enabling greater convenience and access to health care services. Key barriers and challenges in adopting and using virtual care appear to primarily arise from patients’ lack of knowledge, understanding, and familiarity with respect to virtual care. Cost, technological access, connectivity, and low digital literacy were challenges for some patients, particularly in rural communities and among older patient population. Patient education and support were critical and needed to be inclusive, easy to understand, and include information regarding privacy, security, consent, and the technology itself. The types of patient education experiences regarded as most helpful included peer support and knowledge sharing among patients themselves.

Conclusions

Beyond the COVID-19 pandemic, virtual care will have a continuing role in enhancing the continuity of care for patients through more convenient access. The education and informational needs of patients are important considerations in promoting the adoption and use of virtual care. Key education and informational needs and strategies were identified to enable and empower patients with the knowledge, digital literacy skills, and support to effectively use virtual care.

BACKGROUND

The COVID-19 pandemic's aftermath has made it clear that it's important to pay great attention to how the general populace reacts to an outbreak. Thus, it is critical to understand the general public's knowledge and attitudes concerning the recent monkey pox outbreak and monkey pox prevention. A core informed population is provided by university students in health faculties, and this population can be used to investigate public health. Assessing students' knowledge of and attitudes toward emerging zoonotic viral diseases can assist enhance their coursework and taught material if knowledge gaps are found.

OBJECTIVE

To evaluate nursing students' knowledge of and attitudes toward monkey pox infection at xxx University in xxx.

METHODS

Pre/posttest quasi-experimental research methodology was used in the current inquiry, which involved 250 nursing students, at the faculty of xxx, one of the health colleges inside xxx University-. A standardized, anonymous, and closed-ended questionnaire was used to collect the information. It comprised three sections: one for participant sociodemographic information, another for an assessment of their knowledge of the monkey pox virus, and a third for an assessment of their attitudes toward it.

RESULTS

Two hundred fifty (250) students in all took part in the study. 50.8% of the studied sample aged 20+ years old with Mean± SD of 20.8±13.5, 56% are female and 48% are in the 3rd academic year. The overall knowledge score on the monkey pox dramatically increased from 45.43±6.29 before the intervention to 65.03±2.93 after it, from 56.62 prior to intervention to 70.65 following it, the overall Monkey pox attitude score increased significantly. Additionally, the results demonstrated that there were substantial statistically significant disparities in the knowledge and attitudes of the study group about monkey pox. Additionally, when considering all demographic details of the study group, the mean difference in scores for both knowledge and attitude is statistically significant. The study intervention was independently reliable and statistically significant as a positive predictor of the study sample's knowledge and attitude.

CONCLUSIONS

Following the program's execution, the current study found that the targeted students had a good knowledge of the disease and a positive attitude toward it.

Microwave-assisted acid hydrolysis has an impact on the characteristics of nanocrystalline cellulose (NCCs). In this study, NCCs was prepared from banana peduncles through hydrolysis of sulfuric acid (concentrations of 1, 2, and 3 M) and hydrolysis time (0.5 and 1.5 h) assisted by microwave and ultrasonic energy to obtain the best NCCs. The characterization of NCCs properties, namely, yield, morphology, functional groups, crystallinity, heat resistance, particle size, and color. The results showed that the yield of NCCs decreased as sulfuric acid concentration and the time length of hydrolysis increased. The FTIR spectra of NCCs showed the most relevant molecular bands, namely O–H, C–H, and C–O, at the wavenumbers range of 3200–4000, 2500–3200, and 500–1500 cm−1, respectively. The TGA test showed that the decomposition of NCCs occurred at a temperature of 275.35–409.40 °C, with a weight loss ranging from 84.00% to 94.09%. Crystallinity index and crystal sizes range from 53.99% to 57.33% and 22.35 to 36.28 nm, respectively. The brightest color of NCCs powder was generated with 1 M sulfuric acid and a hydrolysis time of 0.5 h. In conclusion, barangan banana peduncles waste can be used as raw material for producing NCCs.

Published: February 2023

Betaine derivatives are widely used in cosmetic, industrial uses, biology and other scientific fields. Pyrimidinium betaine is a special class of bioactive heterocyclics. They have interesting antioxidant and free radical scavenging activities. This work aims to examine the influence of some parameters on the antioxidant activity of some synthesized betaines containing pyrimidine ring. Four pyrimidinium betaines: monocyclic, bicyclics, and one with a fatty alkyl chain were synthesized from condensation of 2-aminopyrimidine or amidine derivatives with malonic esters, and their antioxidant capacity was evaluated. The effects of concentration, reaction time and temperature on their antioxidant activities were investigated by three common methods: 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging, ferric reducing antioxidant power (FRAP) and β-carotene bleaching. The results showed that all pyrimidinium betaines exhibited antioxidant activities in different assays. In the DPPH and reducing power assays, antioxidant activity increased with concentration, whereas in the β-carotene/linoleic acid system, it increased with temperature. On the other hand, the DPPH assay showed an increase in antioxidant capacity over time, while the β-carotene bleaching assay showed a decrease. These results indicate that the antioxidant activity differs depending on the method used and that the various factors affect the antioxidant activity in a different order.

The potential of dye-sensitized solar cells (DSSC) as an alternative to depleting fossil fuels has been investigated. To optimize performance and efficiency, the effectiveness of PVDF and PVDF nanofiber (NF) membrane-based electrolytes in suppressing solvent leakage and evaporation in liquid electrolyte systems was evaluated. SEM results for PVDF NF membranes showed the formation of a network with a three-dimensional structure with a diameter of 100–300 nm and an average thickness of 0.14 mm. The Infrared (IR) spectrum shows the electrolyte and polymer-PVDF interactions. Differential Scanning Calorimetry (DSC) curve shows the melting transition of PVDF NF 7.66% lower than PVDF. Efficiency and resistance of DSSC based on natural dyes as measured by multimeter and Electrochemical Impedance Spectroscopy (EIS) at a solar intensity of 100 mW/cm2 showed the highest efficiency of anthocyanin-based DSSC from telang (Clitoria ternatea L.) flower extract. Its use as a photosensitizer in an electrolyte system based on PVDF NF membranes resulted in an efficiency that was not significantly different from that of liquid electrolytes (1.69%).
