Effective hydrogen supply chain management framework considering nonlinear multi-stage process uncertainties

The large amount of carbon emitted due to industrial development is posing serious climate change. Under these circumstances, hydrogen energy is being used as a major energy source and is attracting attention as an alternative energy to fossil fuels, characterized by high carbon emissions. While the use of hydrogen has the obvious benefit of a low carbon footprint, the hydrogen production process possesses a high carbon footprint difference depending on the source of utilized electricity. This study considers several situations arising in an electrolysis-based hydrogen supply chain network (HSCN). A multi-stage stochastic programming (SP) is modeled to consider the uncertainty of demand and transportation capacity generated in HSCN. Moreover, a typical stochastic model has a chain rule between the decision variables resulting from nonlinearity and uncertainty, and these features make it difficult to derive an effective solution. Thus, in this study, a new methodology, Weighted Scenario Sample Average Approximation (WSSAA), is proposed to derive an effective solution for the multistage SP model considering various scenarios under the hydrogen supply chain. While a general stochastic programming approach fails to generate feasible solutions with volatile HSCN uncertainties, the proposed WSSAA framework provides feasible decisions considering multiple scenarios. The effectiveness of the proposed model applied with WSSAA is demonstrated through comparative experiments over the models used in existing studies.

An optimal standalone wind-photovoltaic power plant system for green hydrogen generation: Case study for hydrogen refueling station

Sustainability goals include the utilization of renewable energy resources to supply the energy needs in addition to wastewater treatment to satisfy the water demand. Moreover, hydrogen has become a promising energy carrier and green fuel to decarbonize the industrial and transportation sectors. In this context, this research investigates a wind-photovoltaic power plant to produce green hydrogen for hydrogen refueling station and to operate an electrocoagulation water treatment unit in Ostrava, Czech Republic's northeast region. The study conducts a techno-economic analysis through HOMER Pro® software for optimal sizing of the power station components and to investigate the economic indices of the plant. The power station employs photovoltaic panels and wind turbines to supply the required electricity for electrolyzers and electrocoagulation reactors. As an off-grid system, lead acid batteries are utilized to store the surplus electricity. Wind speed and solar irradiation are the key role site dependent parameters that determine the cost of hydrogen, electricity, and wastewater treatment. The simulated model considers the capital, operating, and replacement costs for system components. In the proposed system, 240 kg of hydrogen as well as 720 kWh electrical energy are daily required for the hydrogen refueling station and the electrocoagulation unit, respectively. Accordingly, the power station annually generates 6,997,990 kWh of electrical energy in addition to 85595 kg of green hydrogen. Based on the economic analysis, the project's NPC is determined to be €5.49 M and the levelized cost of Hydrogen (LCH) is 2.89 €/kg excluding compressor unit costs. This value proves the effectiveness of this power system, which encourages the utilization of green hydrogen for fuel-cell electric vehicles (FCVs). Furthermore, emerging electrocoagulation studies produce hydrogen through wastewater treatment, increasing hydrogen production and lowering LCH. Therefore, this study is able to provide practicable methodology support for optimal sizing of the power station components, which is beneficial for industrialization and economic development as well as transition toward sustainability and autonomous energy systems.

State Capacity and Industrial Development: A Comparative Study of Iran and Egypt (1990–2010)

Despite pursuing industrial development to solve various socioeconomic and sociopolitical issues, such as the urgent need to reconstruct war damages in Iran, the foreign debt crisis in Egypt, and population growth in both countries, statistical data show only slight progress. The graphs of the gross domestic product (GDP) growth and exports of goods and services as a percentage of GDP, which are reliable indexes for measuring industrial output, along with the rate of foreign direct investment, demonstrate numerous fluctuations and instability in the economic growth rate for both cases under the period under review. Failing to diversify the economy, Iran and Egypt still relied heavily on unproductive rents, mostly from hydrocarbon exports, at the end of this era. Why is this the case despite the national leadership putting industrial development on the agenda? This article addresses this question by examining state capacity, focusing on the internal cohesion of state authority and its relation to society. In so doing, comparative historical analysis and causal narrative method are used.

INDUSTRIAL DEVELOPMENT AND COMPARATIVE REVIEW OF BRICS SPECIALIZATIONS

In modern conditions of global economic relations, BRICS is of strategic importance for the member countries of this association. The purpose of the article is to analyze the directions of industrial development of the BRICS and their impact on the foreign trade potential of the member countries of this association. The article highlights the basic stages of analyzing the impact of industrial specializations of countries on their foreign trade. On the basis of the selected stages a macroeconomic review and analysis of the industrial profiles of the BRICS member countries were carried out, in particular, information on basic specialization sectors was systematized, divided into primary, secondary and tertiary sectors of the economy, which occupy significant shares in the GDP structure of the bloc countries and determine the vector of foreign trade (export-import) activities of the countries. Based on the UNCTAD open data base, the authors investigated the radars of comparative advantages of the BRICS countries based on the application of the Balassa coefficient (coefficient of relative advantages), which allowed drawing conclusions about the advantages and export specializations of the BRICS member countries. Conclusions are drawn about the high potential of foreign trade cooperation between the BRICS member countries and more intensive build-up of foreign trade potential taking into account the upcoming expansion of the BRICS in 2024.

The role of BRICS countries in the optimal low-carbon transition path for sustainable development

With the development of industrialization, greenhouse gas emissions caused by human activities, especially carbon dioxide emissions, continue to increase. The BRICS countries (Brazil, Russia, India, China, and South Africa) account for a significant share of global carbon emissions. This study focuses on the BRICS countries as the subject of inquiry, employing carbon emission-related data spanning the temporal range from 2000 to 2020. This study systematically assesses the interrelationships among variables using the Pearson correlation analysis and Granger causality test. Variables exhibiting pronounced correlation and causality, as discerned from the analytical outcomes, are subsequently identified and selected for further examination. Use the GCAM (Global Change Assessment Model) to simulate the Rcp-ref scenario (baseline scenario) and the Rcp2.6 scenario (assuming that the temperature will not rise by 2 degrees Celsius), and compare the optimal paths of key variables in the two scenarios, and draw the following conclusions. (1) By the end of this century, the total carbon emissions of the BRICS countries under Rcp2.6 scenario will be 6139MTC less than those under Rcp-ref scenario. (2) Compared with the Rcp-ref scenario, in the Rcp2.6 scenario, the proportion of fossil fuels such as oil, natural gas, and coal in the main energy consumption significantly reduces, while the proportion of renewable energy sources such as wind, solar, and biomass increases. It is worth noting that the proportion of nuclear is significantly rising. (3) The demand for electricity increases significantly in the Rcp2.6 scenario. This study reveals the specific directions for improving the energy structure of BRICS countries to achieve the global average temperature rise of no more than 2 degrees Celsius. It provides suggestions for the future policies of these countries' governments. In addition, BRICS countries should focus on observing changes in some factors, such as the increase in nuclear energy consumption and the increase in electricity demand. The reasons behind the changes in these factors are the direction of future research.

Hydrochemistry and isotope hydrology of groundwater and surface water in the Sor and Gebba watershed, southwestern Ethiopia

The Sor and Gebba watershed plays a crucial role in the water resources of the Baro-Akobo River Basin. However, various factors have had a detrimental effect on the watershed. Unplanned groundwater extraction, wetland drainage, surface water pollution, and land use changes have all intensified due to population growth, urbanization, commercial farms, industrial development, poor water resources management, and improvements in living standards. This research utilized major hydrochemical ions and environmentally stable isotopes to elucidate the interaction between groundwater and surface water in the watershed, which are reliable tracers in various hydrologic processes. During the 2020 wet season and 2022 dry season, over 25 meteoric water samples were collected from different locations for hydrochemical and isotopic analysis. The hydrochemical analysis revealed that the dominant water type is Ca–Mg–HCO3−. Among the anions, HCO3− was the most dominant, followed by NO3−, Cl−, and SO42−, and those of cations Ca2+, followed by Na+, Mg2+, and K+. The spatial analysis of environmentally stable isotopes confirmed the interaction between groundwater and surface water in the watershed. The quality of groundwater is primarily influenced by rock-water interaction (Gibb's diagram) and, to some extent, by evaporation (Isotope study). A graph of the water samples closely aligned with the Addis Ababa-local meteoric water line indicates their meteoric origin. However, there was a slight deviation to the left due to the effects of distance and altitude. The isotopic correlation further supported the interaction between different water sources.

An exploratory diagnosis and proposed index of technological change and sustainable industrial development in selected OECD member countries

The purpose of this study was to carry out an exploratory diagnosis and propose a technological change and sustainable industrial development index at the international level. Therefore, a network study was conducted to identify the main nodes and thematic clusters associated with cleaner production. A patent analysis was applied to technologies related three selected/relevant areas of cleaner production, i.e. carbon footprint, wastewater treatment, and renewable energy. Additionally, based on factor analysis, an index including different indicators related to scientific, technological, economic, environmental, and social issues was developed and proposed in this study.

Fabrication of controlled porous and ultrafast dissolution porous microneedles by organic-solvent-free ice templating method

Porous Microneedles (PMNs) have been widely used in drug delivery and medical diagnosis owing to their abundant interconnected pores. However, the mechanical strength, the use of organic solvent, and drug loading capacity have long been challenging. Herein, a novel strategy of PMNs fabrication based on the Ice Templating Method is proposed that is suitable for insoluble, soluble, and nanosystem drug loading. The preparation process simplifies the traditional microneedle preparation process with a shorter preparation time. It endows the highly tunable porous morphology, enhanced mechanical strength, and rapid dissolution performance. Micro-CT three-dimensional reconstruction was used to better quantify the internal structures of PMNs, and we further established the equivalent pore network model to statistically analyze the internal pore structure parameters of PMNs. In particular, the mechanical strength is mainly negatively correlated with the surface porosity, while the dissolution velocity is mainly positively correlated with the permeability coefficient by the correlation heatmap. The poorly water-soluble Asiatic acid was encapsulated in PMNs in nanostructured lipid carriers, showing prominent hypertrophic scar healing trends. This work offers a quick and easy way of preparation that may be used to expand PMNs function and be introduced in industrial manufacturing development.

Reproductive cytotoxic and genotoxic impact of polystyrene microplastic on Paracentrotus lividus spermatozoa

In recent decades, industrialization, intensive agriculture, and urban development have severely impacted marine environments, compromising the health of aquatic and terrestrial organisms. Inadequate disposal results in hundreds of tons of plastic products released annually into the environment, which degrade into microplastics (MPs), posing health risks due to their ability to biomagnify and bioaccumulate. Among these, polystyrene MPs (PS-MPs) are significant pollutants in marine ecosystems, widely studied for their reproductive toxicological effects. This research aimed to evaluate the reproductive cytotoxic and genotoxic effects of PS-MPs on sea urchin (Paracentrotus lividus) spermatozoa in vitro. Results showed that PS-MPs significantly reduced sperm viability and motility without altering morphology, and induced sperm DNA fragmentation mediated by reactive oxygen species production. Furthermore, head-to-head agglutination of the spermatozoa was observed exclusively in the sample treated with the plastic agents, indicating the ability of microplastics to adhere to the surface of sperm cells and form aggregates with microplastics on other sperm cells, thereby impeding movement and reducing reproductive potential. These findings suggest that PS-MPs can adversely affect the quality of sea urchin sperm, potentially impacting reproductive events.

Pharmacological Evaluation of Antidiabetic Capacity of Moringa oleifera LAM Leaves

Nowadays, phyto-medicine is considered the best form of modern, scientific herbal medicine, relying on scientific research and the highest professional standards to find effective remedies for diseases including diabetes, since this disease is principally linked to impaired insulin function. The work aimed to evaluate inhibitory capacity of Moringa oleifera LAM (MEMO) (Moringaceae). Methanol extract of this plant was prepared and was delivered to rats and revealed a remarkable decrease in glycaemia state (vs. Glibenclamide, 5 mg/kg). Noting that the biochemical parameters were also evaluated. In addition, the plant extract also inhibited enzymes activities comparing to acarbose (standard). This plant possesses antidiabetic properties. The results showed that the activity of this plant represents a potential candidate to develop new drugs to prevent/treat diabetes and this type of pharmacological research is likely to lead to the industrial pharmaceutical development of new active bio-compounds in countries where tradition remains strong.

Numerical modelling of an effective perovskite solar cell and PV-module for comparison analysis of organic and inorganic electron transport layers

The demand for energy has increased over the past few decades due to both the industrial sector's rapid development and the world's population growth. As we know, the main source of energy consists primarily of fossil fuels, which are expected to be exhausted very soon. Researchers were therefore urged to locate an alternative source of energy that may substitute for fossil fuels in order to meet the world's growing energy needs. Substitute energy sources, like renewable energy, can be used to reduce reliance on conventional energy. As its irradiance may produce electricity when struck by photovoltaic solar (PV) panels, one of the increasingly prevalent types of energy is solar energy. With the help of capacitance simulator software for solar cells (SCAPS-1D), a thorough study of comparison analysis for the design of more efficient, inexpensive, and non-toxic Ni/Cu2O/MASnI3/PCBM/FTO and Ni/Cu2O/MASnI3/WO3/FTO module configurations of solar cells was carried out, and the PVsyst photovoltaic software package investigated the dependence of solar panels on temperature and irradiation. In order to investigate how altering the electron transport layer (ETL) affects conversion efficiency, this work offers a perovskite solar cell simulation with both organic and inorganic ETLs. The absorber layer of perovskite and the HTL (hole transport layer) are maintained uniformly across all ETL configurations. This particular research takes into account the CH3NH3SnI3 absorber layer with Cu2O as HTL. In order to determine which cell combination has the maximum conversion efficiency, we examine the outcomes of both cell combinations. The SCAPS-1D software is used for all simulation work. The power conversion efficiency (PCE) for organic ETL was found to be 28.79%., in addition to a number of electrical parameters like short-circuit current density (Jsc) of 33.42mA/cm2, open-circuit voltage (Voc) of 1.032V, and fill factor (FF) of 83.43%. For inorganic ETL, PCE was 29.54%, Jsc was 34.28mA/cm2, Voc was 1.033, and fill factor was 83.34%. The optimised layer thickness of HTL was 0.2µm, for ETL it was 0.02µm, and the CH3NH3SnI3 absorber layer was 0.8µm. For a solar module with 72 cells with dimensions of 2.2×1.1m, the results obtained from the simulation of electrical parameters derived from SCAPS-1D were configured in the PVsyst software package for panel performance.

Recent progress of modified CeO2-based materials for photocatalytic environmental remediation and antibacterial activity

The rapid development of industrialization and urbanization has led to serious environmental pollution. As an environmentally friendly and sustainable energy source, solar-driven semiconductor photocatalysis has been widely applied in environmental remediation and antibacterial activity owing to its gentle reaction conditions. The use of CeO2-based nanomaterials in green energy production, CO2 conversion, pollutant degradation, and antibacterial is increasing. The photocatalytic performance of CeO2 can be enhanced by appropriate modification strategies that suppress the rapid recombination of electron-hole pairs. This paper provides a systematic introduction to various modification strategies for CeO2, and reviews the research progress of modified CeO2 materials in photocatalytic CO2 reduction, photocatalytic hydrogen evolution, heavy metal removal, photodegradation of organic pollutants, and antibacterial fields, finally offering perspectives on its future development direction.

Synthesis Bi2O3/gC3N4 heterostructures: Investigation structural, morphological and photocatalytic activity towards methylene blue and rhodamine B

Waste from various dyes as a result of industrial development is an important source of pollutants for water resources; These wastes are frequently carcinogenic, mutagenic and toxic to aquatic life, so treating wastewater is vitally important. Photocatalytic purification is a popular method because it can break down dye molecules and change them into non-toxic, small and harmless species. Moreover, utilizing the power of sunlight, this technology holds significant promise for enabling environmentally friendly, sustainable, and economically viable technologies. The non-toxic polymeric photocatalyst graphitic carbon nitride (gC3N4) is an n-type semiconductor. Its facile and economical synthesis, effective band structure, and stability make it a popular option for photocatalytic investigations. It is crucial to develop nanocomposites to boost the capacity of materials for photocatalysis. The objective of this study is to fabricate nanocomposites of graphitic carbon nitride from thiourea, incorporating varying ratios of bismuth oxide through thermal condensation. The aim is to employ these composites for the catalytic degradation of Methylene Blue (MB) and Rhodamine B (Rh B) dyes. The synthesized samples' morphological and structural characteristics were studied. Their photocatalytic activity against methylene blue and rhodamine B dyes has also been reported. The Bi2O3/gC3N4 heterostructured samples were prepared considering bismuth nitrate and thiourea at weight ratios of 0.125:10, 0.25:10, and 0.5:10. In the study, the Bi2O3/gC3N4 heterostructured sample with the lowest bismuth doping rate was seen to have the highest photocatalytic degradation efficiency. A remarkable degradation rate, reaching 98.83 % within 70 min for MB and 98.59 % within 60 min for RhB dye was observed. The enhanced photocatalytic activities of the synthesized composite can be attributed to the synergistic effect of the heterostructure developed between graphitic carbon nitride and bismuth oxide. As a result, this study has shown promise that Bi2O3/gC3N4 composite photocatalysts can be an effective material for removing dyes.

Analysis of yellow mealworm (Tenebrio molitor) frass as a resource for a sustainable agriculture in the current context of insect farming industry growth

With the ongoing rapid growth of the human population, the industrial development of mass insect rearing for feed and food is gaining momentum. This approach has proved to be a more efficient and effective alternative to traditional livestock to produce animal protein. In this context, the Tenebrio molitor production sector emerges as highly promising in the edible insect market, being among the most commonly bred species in the large-scale insect rearing industry. A recent modification of the European regulatory framework in this matter has authorized insect-produced feed for pigs and poultry, which will boost the creation of new insect industries, resulting in huge quantities of frass, the insect excrement, that could be valorized. This by-product holds substantial amounts of nutrients and advantageous microorganisms that have enormous potential for organic farming. It typically exhibits high organic content and an abundance of essential nutrients like nitrogen (N), phosphorus (P), and potassium (K), alongside a narrow carbon (C) to nitrogen (N) ratio. In addition to providing plants with essential macronutrients, frass has been discovered to boost soil microbial biomass and introduce biomolecules and microbes that foster plant growth. The study of utilizing frass in sustainable agriculture is a relatively new and actively researched field in recent years. By conducting a comprehensive review of peer reviewed papers, this article highlights the advantages associated with the effects of its use as organic fertilizer. Among these, the effect of frass as (1) a plant growth promoter and productivity enhancer and as (2) phytofortifyer against biotic and abiotic stresses, has been underlined in recent studies. With regard to its promoting effect, it has been observed that the effects of frass depend very much on its dose and the type of crop, with remarkably favourable results in many of the tests carried out. Hence, frass derived from the mass rearing of yellow mealworm for feed and food, could serve as an important and potent source of organic fertilizer in intensive horticultural crops or in high-value woody crops, contributing to a more sustainable agriculture, which can decrease the use of conventional synthetic agrochemicals.
