AbstractA modular synthesis of novel series of 1,7‐difluorinated BODIPYs has been elaborated. First, the acid‐catalyzed condensation of ethyl 3‐aryl‐4‐fluoro‐1H‐pyrrole‐2‐carboxylates with aromatic aldehydes gives the corresponding dipyrromethane‐1,9‐dicarboxylates. The latter are subjected to the exhaustive reduction with lithium aluminum hydride to transform the ester moieties into methyl groups. The subsequent oxidation of the resulting 1,9‐dimethylated dipyrromethanes followed by the boron difluoride complexation afforded a family of novel core‐fluorinated BODIPYs in up to 74 % yield. Photophysical properties of the resulting BODIPYs were tuned by varying of the starting fluoropyrroles and aromatic aldehydes and were studied by UV‐visible and fluorescence spectroscopy. As a result, the fluorescence quantum yields of the obtained compounds reached up to 99 %. In addition, their ability to generate singlet oxygen and electrochemical properties were also evaluated. As a result, a new promising family of fluorophores with a good combination of the fluorescence and photosensitizing properties was obtained. It was found that conversion of ester groups into methyl ones at the 3,5‐positions of the BODIPY core is a crucial step toward fluorescence enhancement. In addition, DFT calculations were performed to elucidate a relationship between electronic structure, geometry and photophysical properties of these BODIPYs.

AbstractRecurrent selection is an effective and well‐known breeding method recommended for quantitative traits. However, the method has not been applied so far for traits typically controlled by numerous major loci, which is the case of resistance to anthracnose in common bean (Phaseolus vulgaris L.). In this study, we report the effectiveness of a recurrent selection program in developing common bean progenies with resistance to multiple races of Colletotrichum lindemuthianum, the causal agent of anthracnose in this crop. A total of 10 common bean lines, with distinct and complementary resistance profiles to races 65, 73, 81, and 89 of C. lindemuthianum, were intercrossed to establish a base population (Cycle 0). From Cycle 0, five iterative cycles of recombination, inoculation, and selection were carried out. Our results demonstrate that this recurrent selection approach can effectively combine resistance in common bean to different isolates from multiple races of C. lindemuthianum. A progressive increase in the number of progenies resistant to a higher number of C. lindemuthianum isolates was observed over the selection cycles. The genetic gain from CI to CV was 38.75% when the progenies were evaluated against a mixture of isolates from the four races of the pathogen. The reliance on specific genes makes race‐specific anthracnose resistance in common bean vulnerable to breakdown. By allowing optimal combinations of different anthracnose resistance genes, this dynamic recurrent selection approach is an attractive option for the development of common bean cultivars with increased stability and durability for anthracnose resistance.

Published: August 2024

AbstractThe relationship between ownership structure and environmental performance has long been a subject of debate in the literature. This study investigates the effects of various ownership characteristics on environmental performance within the energy sector firms of G20 countries. We hypothesize that ownership concentration, as well as institutional, government, and foreign ownership, are significantly associated with firms' environmental performance. Using a dataset of energy sector companies from 2018 to 2022, collected from the Thomson Reuters Eikon database, we employ multiple linear regression analysis to test our hypotheses. The results reveal that foreign ownership is significantly and positively related to environmental performance. In contrast, institutional ownership has a significant negative effect on environmental performance. We also find that the developed G20 countries have a stronger influence on the overall sample results compared to the developing G20 countries. These findings contribute to the ongoing debate on the role of ownership structure in shaping corporate environmental practices, with important implications for policymakers, regulators, and energy companies operating within the G20 context.

AbstractThe sluggish transition and shuttle of polysulfides (LiPS) significantly hinder the application and commercialization of Li−S batteries. Herein, carbon nanotubes (CNTs) supported 10 nm sized iron Hexadecafluorophthalocyanine (FePcF16/CNTs) are prepared using a solid synthesis approach. The well‐exposed FePcF16 molecular improve the LiPS capture efficiency and redox kinetics by its central Fe−N4 units and F functional groups. The strong electron withdraw F groups significantly promote the conjugate effect and decrease the steric hindrance during mass migration procedure. Distribution of relaxation time (DRT) analysis shows that the Fe−N4 units exhibit strong affinity towards LiPS and the F groups further improve the Li+ diffusion rate in Li2S nucleation and oxidation procedure, accomplishing a porous surface on cathode. As a result, the FePcF16/CNTs separator exhibits a high initial capacity of 1136.2 mAh g−1 at 0.2 C, outstanding rate capacity of 624.9 mAh g−1 at 5 C and superior long‐term stability at 2 C surviving 300 cycles with a low capacity decay of 0.43 ‰ per cycle.

AbstractThe direct one‐step hydrogenation of toluene to methylcyclohexane facilitated by a proton‐exchange membrane water electrolyzer driven by renewable energy has garnered considerable attention for stable hydrogen storage and safe hydrogen transportation. However, a persistent challenge lies in the crossover of toluene from the cathode to the anode chamber, which deteriorates the anode and decreases its energy efficiency and lifetime. To address this challenge, the catalyst‐poisoning mechanism is systematically investigated using IrO2 and high‐entropic non‐noble‐metal alloys as anodes in acidic electrolytes saturated with toluene and toluene‐oxidized derivatives, such as benzaldehyde, benzyl alcohol, and benzoic acid. Benzoic acid plays an important role in polymer‐like carbon‐film formation by blocking the catalytically active sites on the anode surface. Moreover, Nb and the highly entropic state on the surface of the multi‐element alloy lower the adsorbing ability of toluene and prevent polymer‐like carbon film formation. This study contributes to the design of catalyst‐poisoning‐resistant anodes for organic hydride technology, advanced fuel cells, and batteries.

AbstractSelective aerobic oxidation of 5‐hydroxymethylfurfural into 2,5‐diformylfuran has been achieved on alkali doped Ru/C catalyst. Optimization of Ru metal nanoparticles, as well as the nature and amount of the alkali dopant have been performed. The results showed that doping the Ru/C catalyst with controlled amount of potassium increases the catalytic activity, 2.5 fold with respect to the non‐doped sample. Spectroscopic studies showed that these differences in activity can be attributed to a different oxidation reaction mechanism associated to the presence of electron rich Ru species in the promoted sample that facilitate the dissociation of O2, while prevents the oxidation of the metal. The Ru/C−K doped catalyst resulted very stable against leaching and metal sintering, being possible the reuse over several consecutive runs. Moreover, the catalyst could be successfully applied to the oxidation of different alcohols.
Decongestion in acute heart failure: Is it time to change diuretic‐centred paradigm?
Authors: Biegus Jan , Cotter Gad , Metra Marco , Ponikowski Piotr 
Published: August 2024

AbstractCongestion is a common cause of clinical deterioration and the most common clinical presentation at admission in acute heart failure (HF). Therefore, finding effective and sustainable ways to alleviate congestion has become a crucial goal for treating HF patients. Congestion is a result of complex underlying pathophysiology; therefore, it is not a direct cause of the disease but its consequence. Any therapy that directly promotes sodium/water removal only, thus targeting only clinical symptoms, neither modifies the natural course of the disease nor improves prognosis. This review aims to provide a comprehensive evaluation of the current decongestive therapies and propose a new (not diuretic‐centred) paradigm of long‐term congestion management in HF that attempts to correct the underlying pathophysiology, thus improving congestion, preventing its development, and favourably altering the natural course of the disease rather than merely treating its symptoms.
Ion Size, Electron Rate and Transfer Coefficient Effect on Hetrocharge Redox Couple (+1,0) for 2‐D Microdisk, Potential Application for Lithium Ion Battery
Authors: Taherkhani Farid 
Published: August 2024

AbstractNumerical finite element simulations were conducted to study the electrochemical reaction in a mixture of hetrocharge redox couple in the presence of a supporting electrolyte as a potential application in lithium ion battery, occurring on both parallel and non‐parallel two dimensional (2‐D) microdisk electrodes. Ion size of supporting electrolyte and electron transfer rate by engineering of electrode types have significant effect on electrical storage. This study represents the first‐time exploration of the electrochemical behavior for hetrocharge +1,0 redox couple in presence of supporting electrolyte on a non‐parallel 2D microdisk. Impedance spectra were calculated for the electrochemical reaction on the non‐parallel 2D microdisk under varying concentrations of the redox couple and supporting electrolyte. COMSOL simulation were extended to investigate the effects of electron rate and transfer number on the Impedance spectrum, as well as the concentration of all ions and electrical potential within the electrical double layer area for the 2‐D microdisk. Analytical expressions were derived to describe the potential and concentration profiles in the double layer area, specifically for the electrochemical reaction involving hetrocharge redox couple +1, 0 on a 2‐D parallel microdisk in the presence of the supporting electrolyte. The study explored the influence of different types of supporting electrolytes, namely KF and KBr, on the impedance spectrum, concentration profile, and electrical potential profile within the electrical double layer area for the non‐parallel 2‐D microdisk. General trend of numerical impedance spectrum result with the ion size of supporting electrolyte is agreement with the available experimental data.

AbstractVoltammetric methods hold promise for the rapid and sensitive quantification of melatonin. This study reports the direct electrochemical quantification of melatonin using carbon nanotube (CNT) fiber cross‐sections as microelectrodes. Six identical highly densified CNT fiber cross‐sections were employed to quantify melatonin in the range of 0.05–100 μM. The limit of detection and quantification were 10 and 35 nM, respectively, with a sensitivity of 0.1322 nA/μM. Interference studies with uric acid, hypoxanthine, and ascorbic acid demonstrate its performance. Real‐world application was highlighted by measuring melatonin in food, pharmaceutical, and human urine samples.

Published: August 2024

AbstractMicroRNAs (miRNAs) play important roles in posttranscriptional gene regulation. Aberrations in the miRNA levels have been the cause behind various diseases, including periodontitis. Therefore, sensitive, specific, and accurate detection of disease‐associated miRNAs is vital to early diagnosis and can facilitate inhibitor screening and drug design. In this study, we developed a label‐free, real‐time sensing method for the detection of miR31, which has been frequently linked to periodontitis, using an engineered protein nanopore and in the presence of a complementary ssDNA as a molecular probe. Our method is rapid and highly sensitive with nanomolar concentration of miR31 that could be determined in minutes. Furthermore, our sensor showed high selectivity toward the target miR31 sequence even in the presence of interfering nucleic acids. In addition, artificial saliva and human saliva samples were successfully analyzed. Our developed nanopore sensing platform could be used to detect other miRNAs and offers a potential application for the clinical diagnosis of disease biomarkers.

Published: August 2024

AbstractThe transformation of power system networks is slowly taking shape, the advent of interruptive technological platforms dealing with digitalization and real‐time trading of power has gained attention based on incorporation of more renewables into the grid. The stochastic nature of renewables pauses security of supply challenges and other related stability concerns, and for this reason efficient methods are investigated in this review to build an understanding of microgrid energy management system (MG‐EMS) and distribution‐based energy management strategies aimed at transforming the conventional grid network into smart grid network. In essence, propagating a technological shift to microgrids which have proven to be ideal distribution networks for residential and commercial loads, have become indispensable in handling distributed energy resources (DER), such as solar, PV, wind, battery energy storage systems (BESS) and small‐scale microgrids, for example in case of excess supply, energy storage system (ESS) has been formulated as a solution to curb excess supply and can offer ancillary services to the grid network. Within the perspective of electricity generation and distribution, microgrid control methodologies, distribution network (DN) management approaches and incumbent optimization strategies used to coordinate and manage grid‐level uncertainties are investigated. In addition, this study proposes distributionally robust optimization (DRO), to manage and mitigate risks associated to shortage or oversupply of power from RESs.

Authors: Rodríguez‐Melcón Cristina , Alonso‐Calleja Carlos , Capita Rosa 
Published: August 2024

AbstractAccording to the World Health Organization, contaminated food causes approximately 600 million cases of illness and 420,000 associated deaths worldwide each year. In this scenario, food safety is a crucial task, which is based in the application of correct hygiene practices throughout the entire food production chain: from farm to table. Ensuring food safety requires the implementation of practical, comprehensive, affordable, and effective approaches such as Hazard Analysis and Critical Control Points, Good Agricultural Practices, Good Manufacturing Practices, use of low cost technologies for traceability, regular inspection and auditing, as well as education and training, among other factors. In addition, it is essential to establish more comprehensive strategies based on the One Health approach. Since human health and animal health are interdependent and linked to the health of the ecosystems in which they coexist, collaboration between multiple disciplines is necessary to achieve optimal health for people, animals, and the environment. Within the food system, the One Health approach can be useful, for example, in the fight against zoonoses or antibiotic resistance. This paper describes various aspects related to the main biotic food‐borne diseases, the problem of biofilms and the impact of different antimicrobials (whether biocides or antibiotics) on antibiotic resistance, listing a range of alternatives to the use of classic sanitizing compounds. All of this has the aim of giving an overview of the different factors, including those connected to the environment or animal health, which can influence food safety and thus public health.

AbstractBean paste is a traditional Chinese fermented condiment, which is loved by consumers for its pleasant flavor and nutritional properties. However, the microbial communities and related flavor compounds in bean paste remain unclear. We studied the correlation between the core functional microorganisms and flavor compounds in bean paste samples at different fermentation stages. Bacterial and fungal communities changed significantly during fermentation. The results indicated that the dominant bacterial genera were Staphylococcus, Lactococcus, and Bacillus. The dominant fungi were Aspergillus and Lichtheimia. During the early and late stages of bean paste fermentation, alcohols, hydrocarbons, esters, and phenols were the main flavor compounds detected. The types and proportions of alcohols and esters in the bean pastes fermented for different durations were similar, whereas the relative contents of phenols and hydrocarbons were higher in the later stages of fermentation. Correlation analysis revealed that core functional microorganisms played a key role in the fermentation process, and the potential correlation between bacterial genera and flavors was stronger than that of fungal genera. Staphylococcus abundance was significantly correlated with the flavor levels of ethyl oleate, ç‐pinene, diallyl disulfide, á‐myrcene, D‐limonene, and tetradecanoic acid, ethyl ester. The abundance of Aspergillus and Lichtheimia was significantly correlated with the flavor levels of á‐myrcene, ç‐pinene, and DL‐3‐phenyllactic acid. This study explored the relationship between microorganisms and flavor compounds in bean paste to deepen our understanding of the mechanism of flavor formation for bean paste.

Published: August 2024

AbstractMilk‐derived exosomes (MDEs), being a component of milk, have the potential to support immune system maturation in offspring and enhance immune cell proliferation. Through the transport and transmission of essential signaling molecules, MDEs contribute to the regulation of intergenerational and intraspecies communication, thereby impacting nutrient uptake and metabolic functions. A comprehensive comprehension of MDE functionalities is imperative for enhancing the quality of the dairy industry. A systematic search of the databases PubMed/Medline, Web of Science, and Scopus utilizing predetermined keywords resulted in the identification of 418 articles, of which 67 were chosen for inclusion in this review, which specifically explores the intersection of immune response and nutrition. This article provides a critical analysis of the classification of extracellular vesicles, the mechanisms underlying the biosynthesis of microvesicular dietary exosomes (MDEs), the components of MDEs, and their relevance in the contexts of nutrition and immune modulation. The primary aim of this review was to offer valuable scholarly insights to support the advancement and practical application of MDEs.
Induzierte Erschütterungen von Bauwerken auf Pfahl‐ und auf Flachgründungen – ein Vergleich über numerische Berechnungen
Authors: Hartmann Hans‐Georg 
Published: August 2024

AbstractBei der Prognose von Bauwerksschwingungen infolge Erschütterungsquellen in der Nachbarschaft, z. B. aus Verkehr, Baumaßnahmen oder Maschinenschwingungen, stellt sich mitunter die Frage, welchen Einfluss die Gründung des Bauwerkes auf Amplitude und Frequenzgehalt der resultierenden Schwingungen hat. In diesem Beitrag werden die sogenannten induzierten Erschütterungen von Bauwerken auf Pfahl‐ und auf Flachgründungen auf der Basis von numerischen Berechnungen systematisch miteinander verglichen. Nach einer Beschreibung der Berechnungsmethode mit der „Thin Layer Method“ (TLM) im Frequenzbereich werden zunächst Einzelpfähle im homogenen Halbraum sowie solche in einer Bodenschicht auf steiferem Untergrund betrachtet. Angeregt durch horizontale und vertikale Kräfte an der Bodenoberfläche in einigem Abstand werden die Amplituden der Schwinggeschwindigkeit (Schwingschnellen) in Höhe des Pfahlkopfes vor und nach Einbau des Pfahles ermittelt und verglichen. Es werden dabei Frequenzen zwischen 1 Hz und 40 Hz betrachtet. Der Einfluss der Bodenschichtung wird diskutiert. Im zweiten Teil der Arbeit werden die Schwingschnellen von Flach‐ und Pfahlgründungen unter gleicher Anregung berechnet und miteinander verglichen. Es werden charakteristische Unterschiede aufgezeigt. Zur Berücksichtigung der aufgehenden Bauwerke werden diese stark vereinfacht als starre Massen modelliert. Die Berechnungsergebnisse leisten einen Beitrag zur einleitenden Fragestellung.
