Authors: Sotiriou Eleni , Patsatsi Aikaterini , Tsorova Christina , Lazaridou Elisabeth , Sotiriadis Dimitrios
Published: April 2023

Febrile ulceronecrotic Mucha-Habermann disease is a severe variant of pityriasis lichenoides et varioliformis acuta characterized by the sudden onset of ulceronecrotic skin lesions and associated with high fever and systemic symptoms. We report here a case of a 20-year-old woman in whom the disease started as pityriasis lichenoides et varioliformis acuta and evolved to febrile ulceronecrotic Mucha-Habermann disease. Almost 90% of the body surface was involved, together with high fever and malaise. Steroids alone proved to be an insufficient therapeutic procedure. The remission achieved was attributed to the use of methotrexate. To our knowledge, only 39 cases of febrile ulceronecrotic Mucha-Habermann disease have been reported in the literature to date.

Published: April 2023

Itch is a major feature of many skin diseases, which adversely affects patient's quality of life. Besides disease severity, psychophysiological factors have been proposed to influence the itch sensation. In this review the evidence for a biopsychosocial model of itch is described, focusing in particular on evidence for the effects of personality characteristics, external stressors, cognitive, behavioural and social factors, and the possible mediating role of physiological processes. Research so far indicates that stressors may have a role in the itch sensation of patients with skin diseases. Furthermore, cognitive factors, such as helplessness and worrying, and the behavioural response of scratching have been indicated as possible worsening factors. Overall, findings are in favour of a biopsychosocial model for the itch sensation. However, there is a strong need for more, methodologically sound research in order fully to understand the processes underlying the itch sensation.

Hyperhomocysteinaemia is a well-known risk factor for cardiovascular disease and plays a role in atherothrombosis. Psoriasis is a common chronic and recurrent inflammatory skin disease associated with increased thrombosis. The aim of this study was to examine serum homocysteine levels and their relationships with inflammatory and atherothrombotic markers in psoriasis. Twenty patients with mild or moderate psoriasis and 20 age-matched healthy men were included in this study. Patients with acquired hyperhomocysteinaemia were excluded from both groups. The inflammation markers, mean platelet volume, C-reactive protein and ceruloplasmin levels, were significantly increased in the study group compared with the control group. In the study group there was decreased antithrombin III and total homocysteine levels, for haemostatic parameters. Folic acid levels, cardiovascular risk factors, endothelial inflammation markers and blood coagulation factors demonstrated significant correlations. Folic acid levels correlated inversely with homocysteine and positively with fibrinogen levels. In conclusion, increased homocysteine concentration and inflammation markers may play a role in the atherothrombotic state in psoriasis.

Authors: Anders Halvorsen Jon , Braae Olesen Anne , Thoresen Magne , Holm Jan-Øyvind , Bjertness Espen , Dalgard Florence
Published: April 2023

Adolescents' skin problems can be studied at the population level. The aim of this study was to validate five questions on skin complaints for use in population surveys among adolescents. Of the 260 adolescents aged 18-20 years invited to participate, 217 were included in the study. The prevalence of the adolescents' self-reported complaints were higher than those found during clinical examination by a dermatologist. The overall agreement between the adolescents' answers and recorded clinical signs was: 74% (pimples/signs of acne), 40% (dry skin/xerosis), 81% (rash/signs of dermatitis) and 83% (other skin complaints/other skin findings). No corresponding objective skin sign was recorded for "itch". Repeatability of the adolescents' answers and inter-agreement between the investigators had an overall agreement of 77-97% and a kappa of 0.29-0.93. When using the dermatologist's findings as gold standard, the sensitivity and specificity were best for "signs of acne", 93% and 43%, respectively.
A Randomized Comparison of Acitretin-narrow-band TL-01 Phototherapy and Acitretin-Psoralen plus Ultraviolet A for Psoriasis
Authors: Özdemir Mustafa , Engin Burhan , Baysal Baysal , Mevlitoğlu Inci
Published: April 2023

The combination of retinoids with phototherapy enhances the efficacy of phototherapy and reduces the cumulative ultraviolet dose and duration of the therapy needed to treat chronic plaque psoriasis. Although TL-01 phototherapy has been used widely, there are few data about the effectiveness of the combination of acitretin with TL-01 in treatment of the disease. The aim of this study was to compare acitretin-narrow-band TL-01 phototherapy with acitretin-psoralen plus ultraviolet A (acitretin-PUVA) in psoriasis. We studied 60 patients with moderate to severe plaque psoriasis who were randomly allocated to three times weekly treatment acitretin-narrow-band TL-01 or acitretin-PUVA. The efficacy of treatments was assessed using the Psoriasis Area and Severity Index by a blinded observer. Clearance of psoriasis was achieved in 56.6% of patients treated with acitretin-narrow-band TL-01 and in 63.3% of those treated with acitretin-PUVA. All of these patients remained clear of psoriasis 3 months after finishing the treatments. Mucocutaneous side-effects, such as dry lips and mouth, were the most common complaints in both groups. In conclusion, acitretin-narrow-band TL-01 is an effective and well-tolerated treatment for moderate to severe plaque psoriasis, with a therapeutic effect equal to that of acitretin-PUVA.

Effect of Pentane-1,5-diol and Propane-1,2-diol on Percutaneous Absorption of Terbinafine
Authors: Evenbratt Hanne , Faergemann Jan
Published: April 2023

The aim of this study was to compare pentane-1,5-diol and propane-1,2-diol used as absorption enhancers for cutaneously administered terbinafine. Fresh human skin samples were placed in a continuous flow diffusioncell with a gel containing terbinafine on top of the skin. Receptor fluid samples were analysed using high - performance liquid chromatography. The quantity of gel remaining on the skin surface after completion of each test was weighed and the amount of drug in the skin was analysed. Addition of pentane-1,5-diol or propane-1,2-diol to the gel increased the percutaneous absorption of the drug. The most efficient absorption enhancer in this comparison was 5% pentane-1,5-diol.
Multiple Epidermolytic Acanthomas Must Not be Confused with Genital Human Papillomavirus Infection
Authors: Kukreja Tarun , Krunic Aleksandar
Published: April 2023

We describe two patients with multiple epidermolytic acanthomas on the scrotum initially referred to our clinic as genital warts. Both patients presented with multiple tan-colored warty papules scattered on the scrotal skin. Biopsy revealed hyperkeratosis, hypergranulosis, and clear cell changes consistent with epidermolytic acan thoma. Human papillomavirus was not detected and the lesions cleared rapidly with a liquid nitrogen cryoprobe. Despite only a few reports of multiple epidermolytic acan thomas of the scrotum, it may not be as rare as previously thought. In addition, genital localization of the wart-like lesions may lead to confusion with other conditions such as condylomata acuminata, molluscum contagiosum, or bowenoid papulosis.

Development and optimization of experimental parameters for the detection of trace of heavy metal (Cr) in liquid samples using laser-induced breakdown spectroscopy technique
Authors: Mishra Pratima , Kumar Rohit , Rai Awadhesh Kumar
Published: April 2023

Detection of traces of impurities/elements present in liquid samples using laser-induced breakdown spectroscopy (LIBS) is challenging because the signal intensity is weaker than in the case of solid samples. The present paper deals with the optimization of experimental parameters for different phases of a liquid sample and the improvement of the limit of detection (LOD) in these LIBS experimental setups. LIBS spectra of chromium in the liquid sample have been recorded in three different configurations [laminar flow, i.e., liquid flowing through a small jet, frozen liquid (ice), and liquid deposited on a filter paper]. Experimental conditions for different phases were optimized to get a better signal-to-noise (S/N) ratio and signal-to-background ratio (S/B) in the LIBS spectra. The best S/N and S/B ratio is observed when LIBS spectra is recorded for the liquid deposited on the filter paper configuration. The spectral intensity of Cr is enhanced several folds (36 times) in the LIBS spectra recorded in the filter paper configuration as compared to the laminar flow. The calibration curve method is used to measure the LOD for three different configurations. The better LOD (9.7 ppm for 357.8 nm Cr line) is observed in the case of deposited liquid on the filter paper than the other liquid phase (laminar, 85.5 ppm and ice, 63.7 ppm) configurations.

Aim. To conduct histological analysis of femoral head avascular necrosis in Wistar rats.Materials and Methods. Femoral head avascular necrosis was artificially induced in 12 Wistar rats which have been euthanised at 2, 4, 6, and 8 weeks postoperation (n = 3 per time point). Affected and intact femoral heads were examined by X-ray examination, haematoxylin and eosin staining, and scanning electron microscopy.Results. X-ray examination and haematoxylin and eosin staining showed the progressive development of osteonecrosis from 2 to 6 weeks and initiation of bone repair at 8 weeks postoperation. X-ray examination had less informative value as compared to routine histological examination. Progressive loss of bone volume was accompanied by osteolysis, resorption of hyaline cartilage, and replacement of bone and cartilage tissues with collagen fibers. Scanning electron microscopy provided an opportunity to assess cellular composition and showed that the maximum activity of osteoclasts and osteoblasts occurs at 6 and 8 weeks postoperation, respectively.Conclusion. X-ray examination was dispensable when investigating features of femoral head avascular necrosis. Histological examination using haematoxylin and eosin staining permitted detection of bone resorption, while scanning electron microscopy contributed to high-resolution visualisation of the bone cellular composition.

The mean reversion/persistence of financial cycles: Empirical evidence for 24 countries worldwide
Authors: Lv Shengnan , Xu Zeshui , Fan Xuecheng , Qin Yong , Skare Marinko
Published: April 2023

Research background: The globalization trend has inevitably enhanced the connectivity of global financial markets, making the cyclicality of financial activities and the spread of market imbalances have received widespread attention, especially after the global financial crisis.
Purpose of the article: To reduce the negative effects of the contagiousness of the financial cycles, it is necessary to study the persistence of financial cycles and carve out the total connectedness, spillover paths, and sources of risks on a global scale. In addition, understanding the relationship between the financial cycle and economic development is an important way to prevent financial crises.
Methods: This paper adopts the nonlinear smoothing transition autoregressive (STAR) model to extract cyclical and phase characteristics of financial cycles based on 24 countries during 1971Q1?2015Q4, covering developed and developing countries, the Americas, Europe, and Asia regions. In addition, the frequency connectedness approach is used to measure the connectedness of financial cycles and the relationship between the global financial cycle and the global economy.
Findings & value added: The analysis reveals that aggregate financial cycles persist for 13.3 years for smoothed and 8.7 years for unsmoothed on average. The national financial cycles are asynchronous and exhibit more prolonged expansions and faster contractions. The connectedness of financial cycles is highly correlated with systemic crises and contributes to the persistence and harmfulness of shocks. It is mainly driven by short-term components and exhibits more pronounced interconnectedness within regions than across regions. During the financial crisis, the global financial cycle movements precede and are longer than the business fluctuations. Based on the study, some policy implications are presented. This paper emphasizes the impact of systemic crises on the persistence of financial cycles and their connectedness, which contributes to refining research related to the coping mechanisms of financial crises.
Equivalence scales for continuous distributions of expenditure
Authors: Kot Stanisław Maciej
Published: April 2023

Research background: In the actual sizable populations of households, the standard microeconomic concept of equivalence scales is intractable since its necessary condition of equality of household welfare levels is unlikely to be fulfilled.
Purpose of the article: This paper aims to develop a concept of an equivalence scale, which can be suitable for continuous distributions of expenditures in the population.
Methods: Using household welfare intervals, we get the random equivalence scale (RES) as the ratio of expenditure distributions of the compared populations of households.
Findings & value added: We derive the parametric distribution of RES for the lognormal distributions of expenditures. The truncated distribution of RES is applied to account for possible economies of scale in the household size. A society?s inequality aversion can be helpful when selecting a single equivalence scale. We estimate RES for Poland using microdata on expenditures and subjective assessments of household welfare intervals. The estimated equivalence scales turned out to be very flat and dependent on welfare.

Published: April 2023

Objectives: This study aimed to assess the scale and transmission patterns of coronavirus disease 2019 (COVID-19) in a religious village community in South Korea, to determine the risk factors of transmission, and to evaluate vaccine effectiveness.Methods: An epidemiological survey was conducted, and data were collected and analyzed from 602 villagers in the religious village community. Multivariate logistic regression analysis was used to identify the risk factors for COVID-19 transmission and to evaluate vaccine effectiveness.Results: The outbreak attack rate was 72.1% (434/602). The attack rate was high among women in their 60s, the unemployed, residents living near religious facility (<500 m), and the unvaccinated. Age, the distance between religious facility and residences, and the absence of vaccination were identified as risk factors for transmission. Vaccine effectiveness was 49.0%, and the highest effectiveness was seen in the age group of 59 years or younger (65.8%).Conclusion: This village community was isolated, with little communication with the outside world. However, the frequency of close contact between residents was relatively high, contributing to the spread of COVID-19 in the village even with relatively short exposure. Vaccination rates in the village community were also lower than those in the general public. Public health authorities should consider the potential impact of cultural factors, including religion, that could lead to the exponential spread of COVID-19 in closed village communities.

Climate change is now widely recognized by the scientific community. Nevertheless, its impact on hydrological extremes is not yet known. Half of the world's natural disasters are floods. These disasters result from heavy rainfall, concentrated in time and space. Morocco has experienced floods of exceptional severity in terms of human and economic losses. The catchment area of Wadi Toudgha is located in the South-East of Morocco with an area of 970 km² considered among the most attractive areas for tourists at national and international level, but this basin suffers from hydrological extremes, especially floods for a long time, these hydrological extremes are hydrometeorological phenomena with often dramatic and catastrophic consequences from a material, human and environmental point of view. The methodology adopted in this scientific contribution allows us to assess the risk of floods, it is based on the idea that the risk of these hydrological extremes is the result of the factor of hazard and the factor of vulnerability, this hydrological modelling allows to understand the spatio-temporal evolution of floods and also to determine the extension of floods and historical floods. According to the application, a flood risk map has been produced to allow managers to take mitigation measures in areas likely to be affected by floods and to act more effectively in case of a flood.

In the case of the present study, the three-dimensional PMWIN software was used, which is based on the finite difference method. A numerical modeling of the aquifer in the vicinity of the Bega canal where the component buildings of the ISHO study area are located was carried out. The modeling technique carried out allowed the numerical and hydraulic modeling of all types of sediments necessary to lower the water table in order to safely build constructions with a large foundation depth on the site, especially in the conditions of a significant groundwater supply due to the proximity of the Bega watercourse. Considering the complexity of underground hydraulic phenomena for which there are no exact calculation methods without simplifications, the only viable solution was the use of numerical modeling based on existing methods (element finite, boundary elements, finite differences); these modeling’s are difficult, especially regarding the calibration and validation of the numerical model. The presented method allows the optimization of the number of boreholes, respectively of the captured flows so that, with a minimum energy consumption and a minimum cost of the execution of the boreholes, it is possible to achieve the water level conditions necessary for the realization of underground constructions.

The article presents the characteristics of the Flow Duration Frequency (FDC) curve statistics of the Hornád River and its tributaries for a period of 60 years (1961-2020) and compares the flow duration curves divided into decades (1961-1970, 1971-1980, 1981- 1990, 1991-2000, 2001-2010 and 2011-2020). High flows corresponding to the flow of 10% (Q10) and 25% (Q25), medium flows corresponding to the flow of 50% (Q50) and low flows corresponding to the flow of 70% (Q75) and 90% (Q90) were analyzed. The study covered 7 catchments located in the Hornád river catchment (eastern Slovakia). The greatest variability of flows in individual decades in relation to the multi-year period 1961-2020 was recorded in all threshold ranges at the station in Prešov Sekčov. The highest values were recorded in the range of low flows (Q90), for which the coefficient of variation was 0.38 (Q90) and 0.27 (Q75). A high coefficient of variation Cv was also recorded for the Košické Olšany station in terms of low flows for Q75 and Q90, which were 0.21 and 0.19, respectively. At the remaining stations, the variability of Cv ranged from 0.08 to 0.15 for Q75 and Q90. The variability of high flows (Q10 and Q25) ranged from 0.11 to 0.17 for all catchments except for the Prešov Sekčov station, for which the values were 0.21 and 0.27, and Stratená 0.19 and 0.18, respectively.

The study of the phenomena associated with sediment transport is important to determine if erosion or deposition will occur in a riverbed, the extent of this processes, as well as the time and distance over which it will occur. For a better understanding of these phenomena, it is necessary to identify and study all the factors and parameters that determine the mechanisms of solid transport processes in the riverbeds. Over time, several researchers have developed different formulas for calculating solid loads, models that were later integrated into various hydroinformatics tools. The use of these tools allows comparing the results obtained by applying various calculation models. This paper compares the results of sediment transport modeling in riverbeds using some of these calculation formulas: Engelund-Fredsøe; Van Rijn; Meyer-Peter & Müller; Sato, Kikkawa & Ashida, respectively Ashida, Takahashi and Mizuyama. The modeling is done on a river sector, using the advanced hydroinformatic tool MIKE11 by DHI. Comparing the results obtained by modeling, using various models, with the data obtained from the measurements make it possible to choose the best model for the studied water course.

Published: April 2023

People living in industrialized countries spend most of the time indoors. Therefore, a significant factor for the intake of pollutants by humans can be indoor contaminants like house dust (HD). The two main migration pathways of inorganic contaminants into buildings are the transport of soil and road dust (RD) adhering to footwear and atmospheric particulate matter sedimented inside the building. Additional sources of contaminants can come from activities carried out within the buildings. Some results are available from studies where samples of RD and HD were collected simultaneously. These results are compared with data from two studies where RD and HD samples were collected in the same area in Austria in Spring 2016. Since these samples were analysed by size fractions size dependent concentration ratios can be calculated for various elements. This information provides additional insight on the sources of specific elements.
A study on the relationship between sociodemographic characteristics and job stress and satisfaction among healthcare workers in Turkey during the COVID-19 pandemic
Authors: Tuna Hasan , Türkmen Osman Oğulcan , Albayrak Sirer
Published: April 2023

The aim of this study was to determine the sociodemographic characteristics that affect job stress and job satisfaction in 454 healthcare workers (physicians, nurses, midwives, technicians, and other healthcare personnel) working with COVID-19 patients in primary healthcare institutions in Turkey with a cross-sectional, web-based survey between 9 and 30 August 2021. The survey included a personal information form, a standard job stress scale, and the Minnesota Satisfaction Questionnaire. The levels of job stress and job satisfaction did not differ between male and female respondents. Singles reported lower job stress and higher job satisfaction than the married respondents. Job stress did not differ between departments, but respondents on the front line who worked in a COVID-19 intensive care unit (ICU) (at any point and/or at the time of the study) or the emergency department reported lower job satisfaction than those working in other departments. Similarly, while stress did not differ by educational status, satisfaction of respondents with bachelor’s or master’s degree was lower than that of the rest. Our findings also suggest that working in a COVID-19 ICU and age are significant predictors of higher stress, whereas lower education, working in a COVID-19 ICU, and being married are good predictors of lower satisfaction. Further research should include other sociodemographic variables that may affect stress and satisfaction at work, and similar studies should follow up to see what was left in the wake of the pandemic.
Financial Policy and Companies’ Sustainable Growth
Authors: Naumoski Aleksandar
Published: April 2023

This paper investigates the intercompany-specific characteristics as a determinant of the sustainable growth rate. We researched a sample of companies listed on the Macedonian stock exchanges. We found that the average actual growth rate for the 2010-2019 period is only 0.38%, while the sustainable growth rate was 1.42%. This is because of the poor operating performance of the companies, moderate leverage, and average retention ratio of 82.5% for the whole sample. The actual growth rate in specific years is drastically higher than the sustainable growth rate, while in certain years it is negative. The sustainable growth rate is positively affected by the profit margin, retention ratio, asset turnover, financial leverage, and ROE, and it is negatively affected by the operating cash flow, company size, growth opportunities, and non-debt tax shield.

In the field of underground and surface mining, offshore and onshore exploitation, hydrocarbon distribution, associations of circularity activities are required taking into account the protection of the environment, the safety and security of people, deposits and objectives in the specific productive infrastructures, as well as the responsibility in the regulatory/legislative framework assumed by directives, laws, rules and norms. The circular economy implies the transition to an eco-industry based on reducing the consumption of energy and raw materials, in which mining waste, municipal waste (in fact, all categories of waste, including hazardous waste) have destinations established from the design phases, being included in the cyclical spiral of reuse. The authors emphasize that in this framework, the waste/residues that appear in an exploitation/manufacturing process represent raw materials for other processes. The article deals with aspects related to the technological and managerial consistency in the problem of waste, Refuse-Derived Fuel, co-processing of waste in cement factories, the industrialization of waste for RDF through mechanical, biological treatment and advances the investment proposal of Unit for Advanced Energo-Thermal Treatment of Waste. It is concluded that regarding the industrialization of mining waste and energy in the circular economy, roadmaps are needed for the introduction and development of waste management / (Roadmap to Improve Waste Management) in Romania and other interested countries.

Implementasi Open Government Indonesia melalui Saluran Youtube Resmi Sekretariat Presiden
Authors: Agustina Indah Restasari
Published: April 2023

Inisiasi Open Government adalah berbagai upaya yang dapat membuat pemerintah lebih mudah diakses oleh semua orang yang pada gilirannya akan meningkatkan legitimasi pemerintah di mata publik. Logika media sosial yang menawarkan konektivitas, programabilitas, dan popularitas dapat sangat bermanfaat untuk mendukung transparansi, partisipasi, dan kolaborasi pemerintah dengan masyarakatnya. Pengaplikasian media sosial dalam rangka mewujudkan keterbukaan kepada masyarakat juga dilakukan oleh pemerintah Indonesia dengan membuka saluran YouTube Sekretariat Presiden pada 2019. Saluran ini membagikan informasi berupa konten video dan live stream terkait kinerja pemerintah serta isu-isu terkini. Penelitian ini kemudian bertujuan untuk memberikan penjelasan mengenai pengaplikasian YouTube sebagai implementasi Open government di Indonesia. Penelitian dilakukan secara kualitatif dan menggunakan pendekatan studi kasus deskriptif dengan teori terpadu Open government dan Social Mediatization yang digagaskan oleh Lim, et. al. (2022) sebagai kerangka berpikir. Data diperoleh melalui wawancara semi-terstruktur kepada mahasiswa pascasarjana komunikasi Universitas Indonesia yang juga merupakan Aparatur Sipil Negara (ASN) di bidang kehumasan serta berbagai literatur pendukung lainnya. Hasil penelitian menunjukkan bahwa saluran YouTube Sekretariat Presiden menjadi salah satu sarana yang memberdayakan pemerintahan terbuka serta memungkinkan terjadinya ketersediaan informasi dan transparansi bagi publik. Partisipasi dan kolaborasi menjadi terbatas dikarenakan saluran YouTube ini masih menggunakan komunikasi satu arah, kurangnya umpan balik dari pengelola saluran, dan latar belakang masyarakat Indonesia yang masih mengalami kesenjangan digital. Meskipun demikian, pengaplikasian saluran Sekretariat Presiden dalam inisiasi keterbukaan pemerintah sudah sesuai dengan tujuan kehumasan pemerintah, yakni sebagai sarana diseminasi informasi yang kredibel dan transparan.

Published: April 2023

SYNOPSIS: Low back pain classification systems are structured assessments used to guide choices of more specific treatments. Classification systems examined in randomized controlled trials have limited effects on pain intensity and disability compared to nonclassified interventions. Potential reasons for the lack of efficacy include (1) failing to assess multidimensional factors that contribute to pain, (2) relying on clinician judgement, (3) low accessibility, and (4) poor classification reliability. Overcoming these limitations is critical to deciding whether classification systems can improve clinical practice. Only once these limitations are addressed, can we feel certain about the efficacy, or lack thereof, of classification systems. This Viewpoint guides the reader through some limitations of common classification approaches and presents a path forward to open-access, reliable, and multidimensional precision medicine for managing low back pain.

Рекуррентная формула для вычисления импеданса катодного каталитического слоя в топливном элементе с полимерным электролитом
Authors: Kulikovsky A.A.
Published: April 2023

A recurrent formula for estimating an impedance of the cathode catalyst layer with fast oxygen transport in a polymer electrolyte fuel cell is derived. The catalyst layer is divided into N sub-layers and application of the charge conservation law enables to obtain the nonlinear recurrent relation Zn = f(Zn−1), where Zn is the accumulated impedance of all sub-layers up to the n-th one. Numerical solution of this relation gives the total impedance of the catalyst layer with taking into account variation of the static overpotential of the oxygen reduction reaction along the depth of this layer. The model is simple, robust and two orders of magnitude faster than the standard model based on numerical solution of the differential equation.

Получена рекуррентная формула для вычисления импеданса катодного каталитического слоя c быстрым переносом кислорода в топливном элементе с полимерным электролитом. Каталитический слой разбивается на N подслоев, и применение закона сохранения заряда позволяет получить нелинейное рекуррентное соотношение Zn = f(Zn−1), где Zn — суммарный импеданс всех подслоев вплоть до n-го включительно. Численное решение этого соотношения дает полный импеданс каталитического слоя с учетом переменного вдоль него статического перенапряжения реакции восстановления кислорода. Модель проста, надежна и на два порядка быстрее, чем стандартная модель, основанная на решении дифференциального уравнения.

We have successfully synthesized 2D Silver-Telluride 2D organometallic nanofibers using diphenyl ditelluride (DPDT) as a precursor. The synthesis was carried out by reacting DPDT with AgNO3 in acetonitrile at room temperature (RT) under an inert atmosphere. The resulting material was fully characterized using various techniques, including UV-VIS-NIR spectroscopy, steady-state and excited-state fluorescent spectroscopy, IR-FTIR-ATR spectroscopy, HR ESI MS spectrometry, high-resolution transmission electron microscopy (HRTEM), BF-STEM or HAADF-STEM, and confocal fluorescence microscopy images and conductivity measurements. Initially, the nanofibers were almost non-emissive. However, we observed a remarkable modification after treating the nanofibers with oleylamine under ultrasound treatment. This treatment induced an aggregation emissive effect (AIE) in the solution and solid state, resulting in the formation of a highly red emissive fluorescent material. Overall, our findings demonstrate the successful synthesis of 2D Silver-Telluride 2D organometallic nanofibers and the induction of AIE in the resulting material through oleylamine treatment. This research provides valuable insights for developing new fluorescent materials with potential applications in various fields.
From waste to energy - Photocatalytic anaerobic degradation of microplastics to generate hydrogen
Authors: Weiss Morten , Marschall Roland
Published: April 2023

Microplastics are very prominent pollutants in our environment, and the reduction of microplastics waste in a huge task for our society. Here, microplastics are used as hydrogen source to generate the green energy carrier hydrogen from anaerobic photocatalysis. Using P25 TiO2 as typical photocatalyst, we show that as used model microplastics can act as solid sources for hydrogen. The highest hydrogen evolution rate was observed when LDPE or PET were used, leading to stable hydrogen evolution for several hours.
