Published: July 2023

AbstractManganese dioxide (MnO2) has been extensively investigated as an electrode material for supercapacitors because of its high theoretical capacitance, great abundance, and low toxicity. To obtain satisfactory capacitance performance, in recent years, many efforts have been dedicated to the fabrication of MnO2 nanoparticles that offer a larger specific surface area and an escalated chemical activity. Beyond them, the ideal dispersibility of nanoparticles in a liquid medium is also of vital importance when processing those powdery materials into slurry ones for some particular uses, such as editable and ink‐printing supercapacitor devices. In this study, the as‐synthesized ultrafine MnO2 nanoparticles having excellent dispersibility in water can be prepared via a facile one‐step hydrothermal route, with a uniform size in diameter of 200 nm exhibiting a large specific surface area of ~389.7 m2 g−1, and a high specific capacitance of 135.7 F g−1 at 5 mV s−1.

Impact of independent director network on corporate green innovation: Evidence from Chinese listed companies
Authors: Qiu Qiang , Yu Jinyue 
Published: July 2023

AbstractGreen innovation has an essential impact on harmonizing the relationship between the ecological environment and economic development, and alleviating environmental problems. Drawing on social network theory, this article proposes the relationship between the social network of independent directors and corporate green innovation. Using the data from listed Chinese companies from 2008 to 2020, this study finds independent directors in the center of the network can significantly promote corporate green innovation. The promotion is stronger in non‐state enterprises and heavy polluters. Further research finds that internal and external corporate contexts can influence the relationship between independent director networks and green innovation. With the more slack resources, the higher operational risk level, and the more competitive the market, the role of the independent directors' social network on corporate green innovation is stronger. This article contributes to the understanding of the impact mechanisms of corporate green innovation and also helps promote green innovation.

Published: July 2023

AbstractThis study analyses the problem of multi‐tier supply chains, including suppliers, producers, wholesalers, and retailers. Decision‐makers should analyse the social, environmental, and economic constraints in a multi‐dimensional business context. We analyse these issues by considering the corporate social responsibility (CSR) concerns. A scorecard‐based mathematical model, consisting of mixed‐integer linear programming, is developed to assist fast‐fashion decision‐makers in supply chain policy formulation. The model is validated through a practical case study using IBM CPLEX Optimizer. The results indicate that involving the social aspect can increase the profit compared to considering only the economic impact, under high environmental costs with low return on investment. Furthermore, the mathematical model is able for the case study to optimise the distribution network of the entire multi‐tier supply chain, considering CSR concerns, in less than 5 s. This research has implications for the advancement of multi‐tier supply chain optimisation and provides a basis for future distribution decisions for firm stakeholders.

AbstractImproving the energy share of renewable energy technologies is the only solution to reduce greenhouse gas emissions and air pollution. The high‐performing green battery energy storage technologies are critical for storing energy to address the intermittent nature of renewable energy resources. In recent years, aqueous batteries, particularly Zn‐ion batteries (ZIBs), have achieved and shown great potential for stationary energy storage systems owing to their low cost and safer operation. However, the practical applications of the ZIBs have significantly been impeded due to the gap between the breakthroughs achieved in academic research and industrial developments. The present review discusses the ZIB′s advantages, possibilities, and shortcomings for stationary energy storage systems. The Review begins with a brief introduction to the ZIBs and their charge storage mechanisms based on the structural properties of cathode materials. The scientific and technical challenges that obstruct the commercialization of the ZIBs are discussed in detail concerning their impact on accelerating the utilization of the ZIBs for real‐life applications. The final section highlights the outlook on research in this flourishing field.

AbstractCannabidiol (CBD), the most abundant nonpsychoactive constituent of Cannabis sativa plant, is a promising potential pharmacotherapy for the treatment of diabetes and associated comorbidities. Previous studies have shown the potential of CBD to prevent diabetes in mice, the precise mechanisms of action remain unclear. The purpose of this study was to explore the mechanism of CBD alleviating hyperglycemia. The results demonstrated that CBD reduced blood glucose of STZ‐induced diabetic mice without causing hypoglycemia. To elucidate the possible mechanisms of CBD effect, RNA‐seq analysis was performed on high glucose‐induced human mesangial cells (HMCs). By cluster analysis of differential genes, the results showed that advanced glycation end products‐receptor of advanced glycation endproducts (AGE‐RAGE) pathway‐related genes CCL2 and interleukin‐1β (IL‐1β) play an important role in the biological of CBD. The expression of CCL2 and IL‐1β were significantly increased in HMCs. Whereas, treatment with CBD decreased the expression of CCL2 and IL‐1β. In addition, CBD significantly reduced AGE‐RAGE levels in high glucose‐induced HMCs. Similar results were confirmed in diabetic mice. In conclusion, we discovered for the first time that CBD ameliorates hyperglycemia partly through AGE‐RAGE mediated CCL2/IL‐1β pathway.

AbstractConsiderable acceleration was observed in the guanidine‐base catalysed Claisen‐Schmidt condensation of benzaldehyde and a 17α‐methyl‐18‐nor‐5α,13α‐androstan‐16‐one (1) in the presence of ethylene glycol. Rate‐enhancement effects of various alcohols and diols were compared. In quantum chemical calculations, coordination of the carbonyl group of the substrate was found to reduce the potential barrier to the proton transfer from the α carbon and thus facilitate the formation of the anion that attacks the aldehyde. Both the experiments and the calculations showed that diols enhance the reactivity more efficiently than alcohols. Ethylene glycol/guanidine‐base mixtures were found to be efficient catalysts and solvents in the synthesis of a range of new 17α‐methyl‐18‐nor‐13α‐15‐arylidene steroids. This solvent mixture has a further advantage: the crude products can be isolated by simple extraction after introduction of CO2. It is also shown that by the proper choice of the base, the base/diol mixture can be recycled.
Modeling temporally misaligned data across space: The case of total pollen concentration in Toronto

Published: July 2023

AbstractDue to the high costs of monitoring environmental processes, measurements are commonly taken at different temporal scales. When observations are available at different temporal scales across different spatial locations, we name it temporal misalignment. Rather than aggregating the data and modeling it at the coarser scale, we propose a model that accounts simultaneously for the fine and coarser temporal scales. More specifically, we propose a spatiotemporal model that accounts for the temporal misalignment when one of the scales is the sum or average of the other by using the properties of the multivariate normal distribution. Inference is performed under the Bayesian framework, and uncertainty about unknown quantities is naturally accounted for. The proposed model is fitted to data simulated from different spatio‐temporal structures to check if the proposed inference procedure recovers the true values of the parameters used to generate the data. The motivating example consists of measurements of total pollen concentration across Toronto, Canada. The data were recorded daily for some sites and weekly for others. The proposed model estimates the daily measurements at sites where only weekly data was recorded and shows how the temporal aggregation of the measurements affects the associations with different covariates.
Gallium indium nitrate doped PbS and MoS2 with ligands based photovoltaic cell structure for enhanced efficiency incorporating transformer based module with hydro Ferron chloride thermal sub cell cooling system

Published: July 2023

AbstractA solar photovoltaic cell that is efficient and produces more power while taking up less area by absorbing high‐light energy. To improve the efficiency of the photovoltaic cell (PV), recombination technique is used in the absorption layers of the solar cell. The existing recombination techniques developed by the absorbers have weak interconnectivity, which may leads to defects, and efficiency is reduced due to the high resistance in diffusion length. So, “GNI‐doped PbS and MoS2 with ligands‐based PV structure” is proposed to improve the interconnection between the layers of the Solar cell. Here, gallium nitride (GaN) and indium nitride (InN) act as anode and cathode in first and third layer, to get the better interconnection by interchanging oxide ions where the Gallium Indium nitrate used as semiconductor. To improve the durability, second layer is doped with Bi3+ with Fe3+, which has a rhombohedral perovskite structure. Molybdenum di‐Sulfide (MoS2) is used in the last layer to improve light absorption. To maintain surface passivation, transformer‐based PV module with an HFC Thermal sub cell is employed in which Hydro Ferron chloride combined with Nano graphene platelets is to avoid Potential Induced Degradation and transformers to eliminate the stray current. While implementing, with very low cost the power conversion efficiency of proposed design increased upto 17%.
Cellular antioxidant activity measurement: An alternative to chemical antioxidant methods?
Authors: Granato Daniel 
Published: July 2023

AbstractOxidative stress occurs when the production of reactive oxygen species (ROS) overpasses their degradation and buffering by endogenous antioxidants and those derived from the diet (exogenous antioxidants). In food science and nutrition, assessing antioxidant activity relies on chemical reactions—chemical test‐tube assays—and human and murine cell lines. Usually, an ROS inductor, such as hydrogen peroxide (H2O2) or peroxyl radicals (ROO•), is used to induce oxidation. Some biomarkers related to endogenous protection (i.e., catalase, superoxide dismutase, and glutathione reductase), oxidation‐end products (i.e., malondialdehyde), and intracellular ROS generation can be quantitatively determined. Herein, some insights into using human cell lines and related biomarkers are described, and the downsides of using chemical antioxidant assays are explained. In conclusion, research on antioxidants should be based on using relevant human cell cultures. In contrast, chemical antioxidant assays should be limited to an initial screening as their physiological importance is negligible.

AbstractArgyrolobium roseum (Camb.) Jaub & Spach (Papilionaceae) is a medicinal plant, cultivated in northern areas of Pakistan. The consumption of trace minerals (lead) is very toxic to the vital organs of the body, therefore the overcome of these minerals is very necessary. In this regard, this study aimed to assess the potential pharmacological effect of aqueous and ethanolic extract of Argyrolobium roseum (Camb.) Jaub & Spach against pb‐induced oxidative stress, histological changes in Pb‐induced rats' liver and kidney, and anti‐inflammatory effect. The metal concentrations in liver and kidney homogenates were measured through atomic absorption spectrophotometer. The antioxidant activity was measured through DPPH and FRAP assay. Pb concentrations were significantly higher in liver and kidney homogenates after injection of Pb acetate was given intraperitoneally (45.2 ± 6.8 and 58.8 ± 7.9, respectively; p < .0001). The level of Pb in liver and kidney homogenates was significantly reduced by aqueous and ethanolic extracts of Argyrolobium roseum (Camb.) Jaub & Spach. The Pb + Aq‐600 mg/kg‐treated rats exhibited a protective effect on hepatocytes cells against Pb‐induced liver injury and restored the cells of the kidney. Pb + Aq‐600 mg/kg showed higher antioxidant activity as compared to other treated groups. The highest decreased MDA level was found in liver and kidney homogenate of Pb + Aq‐600 mg/kg rats (11.2 ± 1.51 nmol/mg; p < .001) and GSH and CAT levels tended to normal after treatment of Pb + Aq‐600 mg/kg in rats. The ALAD, ALT, AST, and ALP level were enhanced and tended to be normal after the Aq‐400 and Aq‐600 mg/kg treatment in Pb‐exposed rats. The result showed that 600 mg/kg Aq + Pb exhibited significant (p < .001) anti‐inflammatory activity. The findings of this study concluded that treatment of the aqueous extract of Argyrolobium roseum (Camb.) Jaub & Spach reduces the renal and hepatic damage in Pb‐induced rats and it also decreases oxidative stress via improving antioxidant components.

Published: July 2023

AbstractNovel green intelligent films based on basil seed gum (BSG)/chitosan containing red cabbage extract (RCA) (0, 2.5, 5, and 10, % (v/v)) as a colorimetric indicator for food freshness detection were fabricated by casting method. The physicochemical, barrier, mechanical, and antioxidant characteristics, as well as sensitivity to pH and ammonia gas of smart edible packaging films, were investigated. The interaction of anthocyanin extract as a natural dye with biopolymers in films characterized by FTIR spectroscopy and SEM images revealed their suitable compatibility. The film with maximum anthocyanin content (10% (v/v)) appeared robust color changes against various pH and ammonia gas levels. The color of indicator films when exposed to alkaline, neutral and acidic buffers are indicated with green, blue, and red colors, respectively. The DPPH radical scavenging activity of smart BSG/chitosan films improved from 23% to 90.32% with increasing RCA content from 2.5 to 10% (v/v). Generally, the incorporation of RCA in film structure enhanced their solubility, WVP, ΔE, turbidity, and flexibility, and reduced tensile strength. The observations successfully confirmed the efficacy of pH‐sensitive indicator smart film based on BSG/chitosan for evaluation of fish spoilage during storage.

AbstractBackgroundThe Gene Expression Classifier (GEC) and Genomic Sequencing Classifier (GSC) were developed to improve risk stratification of indeterminate nodules. Our aim was to assess the clinical utility in a European population with restrictive diagnostic workup.MethodsClinical utility of the GEC was assessed in a prospective multicenter cohort of 68 indeterminate nodules. Diagnostic surgical rates for Bethesda III and IV nodules were compared to a historical cohort of 171 indeterminate nodules. Samples were post hoc tested with the GSC.ResultsThe GEC classified 26% as benign. Surgical rates between the prospective and historical cohort did not differ (72.1% vs. 76.6%). The GSC classified 59% as benign, but misclassified six malignant lesions as benign.ConclusionImplementation of GEC in management of indeterminate nodules in a European country with restrictive diagnostic workup is currently not supported, especially in oncocytic nodules. Prospective studies with the GSC in European countries are needed to determine the clinical utility.

Published: July 2023

AbstractAn “OFF/ON” electric current switching protocol was developed as a new strategy for one‐pot organic synthesis. Suzuki‐Miyaura coupling of 2‐bromopyridines with arylboronic acids in an electrochemical cell was performed without applying an electric current, and subsequently, the Pd‐catalyzed electrochemical C−H bromination was conducted using the already‐present Pd catalyst to obtain 2‐(2‐bromoaryl)pyridines as products. The one‐pot synthesis of bromoarenes can also be achieved without adding an external Br source in the second step. Furthermore, an OFF/ON/OFF two‐times switching protocol also realized the formation of an N‐containing teraryl derivative.

Additionally, we wanted to describe reasons for the procedure, associated clinical circumstances, and complications.MethodsThis was a descriptive, population‐based study among women who underwent PH in Slovakia between January 2012 and December 2020. Peripartum hysterectomy was defined as surgical removal of the uterus from the peripartum period up to 42 days postpartum. Data were obtained retrospectively from the standardized questionnaires that are completed in Slovakia for any case of PH. The background population consisted of all other women who delivered during the study period.ResultsOf the 436 136 births, there were 397 cases of PH, giving an incidence of 0.91 per 1000 births. It was higher with advanced maternal age, multiparity, multiple pregnancies, and cesarean deliveries. The main reasons for the procedure were placental pathologies and uterine atony in 52.9% and 33.0%, respectively. A total of 150 (37.8%) women required admission to an intensive care unit. The mortality rate was 1.5%.ConclusionThe incidence of PH is relatively high in Slovakia when compared with other European countries, highlighting the need to improve prenatal diagnosis of morbidly adherent placenta and the management of peripartum hemorrhage.

AbstractObjectivePara‐aminophenol (PAP) is a critical intermediate widely used in medicine, pharmaceutical, rubber, antioxidant, petroleum, and other fields, but it is harmful to the environment. A novel photo electrochemical (PEC) sensor was synthesized and applied to detect PAP based on the composite material of cadmium telluride nanoparticle (CdTe NPs)–decorated copper–tetramine phthalocyanine covalently grafted graphene oxide (CuTAPc‐Gr).Materials & MethodsCopper–tetramine phthalocyanine (CuTAPc) has an excellent PEC conversion effect and narrow band. Graphene (Gr) has high mechanical stability and suitable bandgap. CuTAPc‐Gr was synthesized by chemical covalent bonding. And CdTe NPs@CuTAPc‐Gr composite was prepared by ultrasonic mixing method using CuTAPc‐Gr and CdTe NPs. The morphology and structure of the PEC materials were characterized using scanning electron microscopy and fourier transform infrared spectrometer. PAP contents were evaluated by the Time‐Current method. And the electron transfer rate of the PEC sensor was studied by electrochemical impedance spectroscopy methods.Results & DiscussionCdTe NPs@CuTAPc‐Gr has excellent PEC properties. In the PAP analysis, distinct regular changes in the photocurrent within a linear range of 33.3–1330.0 nM were noted. The limit of detection was 15.5 nM. Acetaminophen, phloroglucin, and other substances did not affect PAP content determination. The water samples were analyzed using the proposed PEC sensor. The results show that the recoveries were in the range of 97.85%–99.58%, and relative standard deviations (RSDs) were less than 2%.ConclusionsThe PEC sensor exhibited excellent sensitivity, selectivity, and stability. The proposed method provides an effective strategy for constructing PEC sensors to detect PAP in water samples and a promising PEC platform for analyzing other small molecules.
