Impact of Electrolyte Composition on Bulk Electrolysis of Furfural over Platinum Electrodes**
Authors: Hasse Joseph C. , Manyé Ibáñez Marc , Holewinski Adam 
Published: September 2023

AbstractPartial oxidation of furanic biomass derivatives such as furfural is of interest for the sustainable production of chemicals including furoic acid, maleic acid, and 2,5‐furandicarboxylic acid (FDCA). The oxidative bulk electrolysis of furfural is here investigated on platinum electrodes in acidic media. The effects of potential, concentration, pH, and supporting anion are studied, and selectivity trends are coupled with attenuated total reflectance surface‐enhanced infrared absorption spectroscopy (ATR‐SEIRAS) to illuminate adsorbate structures that influence the catalysis. Increasing potential is found to shift selectivity from primarily C5 products to C4 products, coincident with oxidation of the Pt surface. Selectivity changes are also observed moving from pH 1 to pH 4, with an increase in C5 products at higher pH. Changing from the weakly adsorbing perchlorate anion to the specifically‐adsorbing phosphate anion results in a number of changes that manifest differently depending on potential and pH. Selectivity to furoic acid is found to be highest above the pKa of phosphoric acid due to the strongly adsorbed phosphate ions suppressing flat‐lying configurations of furfural that lead to C−C cleavage. These results point toward opportunities to use electrolyte engineering to tune selectivity and optimize surface conditions to disfavor binding of inhibitory products.

AbstractPure ZnO particles, doped and co‐doped with Cu2+ and Mg2+ ions, were obtained by the simple sonochemical method. The wurtzite hexagonal structure was confirmed by X‐ray diffraction (XRD) patterns. The images obtained by field emission scanning electron microscopy (FE‐SEM) showed irregular and more agglomerated particles with the increase of Cu2+ and Mg2+ ions concentration in the ZnO lattice, with the average diameter of particles in the range of 57.23–170.77 nm. The photocatalytic activity was investigated by decolorizing the methylene blue (MB) dye under ultraviolet C (UVC) light irradiation which indicates that 1% Mg‐doped ZnO particles have better the photocatalytic activity than the other samples, and presented the highest kinetic constant value. The co‐doped samples showed a reduced global surface area which did not favor the good photocatalytic performance. The sacrificial agents showed that OH• radicals are the main species involved in the photocatalytic activity of this system and defects generated in the ZnO lattice promoted photoluminescent emission in the red and green regions.

AbstractBackgroundAim of the study was to collect and describe a case series of consecutive master athletes in whom an anomalous origin of left circumflex artery (LCx) from the right sinus of Valsalva (ALCx) was detected at a clinically indicated coronary computed tomography angiography CCTA) to establish a focused clinical management and counseling about sport activity in those subjects.MethodsWe analyzed a prospective registry of subjects referred to a clinically indicated CCTA. Information about the clinical status was obtained by previous clinical records and clinical evaluation at time of image acquisition; follow‐up allowed to record symptoms, outcomes and downstream testing.ResultsThe study population consisted in 14 subjects, of which one competitive athlete and 13 recreational master athletes. Mean age was of 67.2 ± 10.6 years (71% of male); follow‐up lasted 6.4 ± 2.6 years. The major high‐risk anatomy features (inter‐arterial course, intramural segment, high take‐off and slit‐like ostium) were absent. None had abnormal ostial morphology and all had full retroaortic course; three subjects (21%) presented an acute take‐off angle. Coronary artery disease (CAD) was present in 10 patients (71%). Major outcomes (cardiac hospitalization, death for all causes) recorded were not related to the anomalous LCx. Symptoms were most related to atherosclerotic CAD in different vessels whereas two subjects without CAD exhibited cardiac symptoms, without hospitalization.ConclusionsOur study suggests that the diagnosis of ALCx, being usually associated to low‐risk anatomical characteristics, could be considered a benign finding, with scarce or no implications for physically active individuals neither for recreational athletes.

Published: September 2023

AbstractRecently, we demonstrated that Pt catalyst complexes dissolved in the ionic liquid (IL) [C4C1Im][PF6] can be deliberately enriched at the IL surface by introducing perfluorinated substituents, which act like buoys dragging the metal complex towards the surface. Herein, we extend our previous angle‐resolved X‐ray photoelectron spectroscopy (ARXPS) studies at complex concentrations between 30 and 5 %mol down to 1 %mol and present complementary surface tension pendant drop (PD) measurements under ultraclean vacuum conditions. This combination allows for connecting the microscopic information on the IL/gas interface derived from ARXPS with the macroscopic property surface tension. The surface enrichment of the Pt complexes is found to be most pronounced at 1 %mol. It also displays a strong temperature dependence, which was not observed for 5 %mol and above, where the surface is already saturated with the complex. The surface enrichment deduced from ARXPS is also reflected by the pronounced decrease in surface tension with increasing concentration of the catalyst. We furthermore observe by ARXPS and PD a much stronger surface affinity of the buoy‐complex as compared to the free ligands in solution. Our results are highly interesting for an optimum design of IL‐based catalyst systems with large contact areas to the surrounding reactant/product phase, such as in supported IL phase (SILP) catalysis.

Published: September 2023

AbstractDespite the growing literature on corporate social responsibility (CSR), little is known about how the board of directors' competence can affect the CSR‐financial performance relationship during severe uncertainties such as the COVID‐19 outbreak. This paper focuses on exploring the mediating role of CSR in the connection between board competence and corporate financial performance amidst global uncertainties. The sample consists of Jordanian companies listed on the Amman Stock Exchange. Data were analyzed using the partial least square structural equation modeling. The findings show that boards' CSR competence has a direct and indirect positive impact on financial performance. Therefore, boards of directors' CSR competence can be seen as enablers for CSR activities. In this regard, companies could invest more in qualifying board directors to be socially responsible and enhance their role in improving corporate financial performance. This study identifies and provides empirical evidence on a critical enabler of CSR activities (i.e., boards of directors' CSR competence) from a developing country perspective. This, in turn, could widen the management and other stakeholders' understanding of CSR‐enhancing factors and therefore increase its efficiency. We provide theoretical and practical implications to guide regulators and businesses to ensure sustainable development.
Nonlinear anisotropic finite element analysis of liquefiable tunnel–sand–pile interaction under seismic excitation
Authors: Haque Md. Foisal 
Published: September 2023

AbstractNonlinear time‐history analysis can be used to determine the liquefiable behaviors of the tunnel–sand–pile interaction (TSPI) model with the consideration of sand anisotropy. This study presents the nonlinear response of the TSPI model with the existence of liquefaction under seismic excitation. The analysis reveals that tunnel and pile behave as isotropic elements, while sand shows isotropic, orthotropic, and anisotropic characteristics. Three constitutive models including UBC3D‐PLM (two yield surfaces associated with the hardening rule), NGI‐ADP (yielding with associated plastic potential function), and a user‐specified constitutive model are adopted to evaluate the isotropic, orthotropic, and anisotropic behaviors of sand. On this basis, two finite element‐based codes (ETABS 18.1.1 and Plaxis 3D) are used to evaluate sand behaviors and responses. Responses of the tunnel, sand, pile, and excess pore pressure ratio are recorded in the interaction zone by varying the pile diameter, tunnel diameter, and tunnel–pile clearance. Compared with the orthotropic and isotropic conditions, lower variations of results are found in the anisotropic condition, except for the case of generation of excess pore pressure. In addition, the present reanalysis results are in agreement with previous analytical and case study results, which further indicates the effectiveness of the finite element‐based numerical codes.

AbstractInformation on diet breadth and preference can assist in understanding links between food resources and population growth and inform habitat restoration for rare herbivores. We assessed the diet of the endangered Pacific pocket mouse using metabarcoding of fecal samples and compared it to plant community composition in long‐term study plots in two populations on Marine Corps Base Camp Pendleton, San Diego County, CA. Fecal samples (n = 221) were collected between spring 2016 and fall 2017 during monthly live‐trap surveys. Concurrently, percent cover and plant phenology were measured in plots centered on trap locations. Fecal samples were sequenced with paired‐end reads of the internal transcribed spacer 2 region of the nuclear ribosomal gene, and the resulting amplicons were matched to a regionally specific database. Seventy‐three plant taxa were detected, which were mostly forbs and perennial herbs (70–90%). Diet composition differed between populations, years, seasons, and plots. Overall, diet and local habitat composition in plots were significantly correlated. However, we detected some differences in above‐ground seed availability and proportion in fecal samples that indicate diet preferences for some forbs, perennial herbs, and native bunch grasses over perennial shrubs and non‐native grasses. This is the first study of PPM to pair plant phenology surveys with diet metabarcoding to estimate resource selection, and results suggest that managing habitat for diverse native forb communities and reducing non‐native grass cover may be beneficial for this critically endangered species.

Published: September 2023

AbstractPhenotypic plasticity is an important avenue by which organisms may persist in the face of rapid environmental change. Environmental cues experienced by the mother can also influence the phenotype of offspring, a form of plasticity called maternal effects. Maternal effects can adaptively prepare offspring for the environmental conditions they will likely experience; however, their ability to buffer offspring against environmental stressors as embryos is understudied. Using captive zebra finches, we performed a maternal‐offspring environmental match‐mismatch experiment utilizing a 2 × 2 × 2 factorial design. Mothers were exposed to a mild heat conditioning (38°C) or control (22°C) treatment as juveniles, an acute high heat (42°C) or control (22°C) treatment as adults, then paired for breeding. The eggs produced by those females were incubated at a hyperthermic (38.5°C) or optimal temperature (37.2°C). We found that when mothers were exposed to a mild heat conditioning as juveniles, their embryos exhibited reduced water loss, longer development times, and produced hatchlings with heavier pectoralis muscles when incubated at high incubation temperatures, compared to embryos from control mothers. Mothers exposed to both the mild heat conditioning as juveniles and a high heat stressor as adults produced eggs with a higher density of shell pores and embryos with lower heart rates during development. However, there was a cost when there was a mismatch between maternal and embryo environment. Embryos from these conditioned and heat‐stressed mothers had reduced survival at control incubation temperatures, indicating the importance of offspring environment when interpreting potential adaptive effects.

AbstractThe synthesis and characterization of Nickel(II) complexes with novel pincer‐type N‐heterocyclic carbene complexes were investigated. Nickel(II)‐NHC complexes, 7 and 8, were characterized using HR ESI‐MS, IR, UV‐Visible, and elemental analysis. The complex 7 with less sterically demanding pincer ligand was investigated in the catalytic one pot synthesis of thioethers via coupling reactions of a series of aryl and alkyl halides in the presence of thiourea. In a mixture of water and ethanol, 5 mol% of 7 catalyzed the C−S bond coupling reaction in high yields.

Published: September 2023

AbstractWith the increasing lifespan of bridges, various forms of deterioration will inevitably occur. The bridge health monitoring system enables direct monitoring of the loads (such as wind, temperature, and vehicles) experienced by the bridge during operation, as well as the corresponding vibration response of the bridge structure (including main beam deformation, tower top displacement, cable acceleration, etc.). These data provide valuable insights into the safety and durability of the bridge during its operational lifetime. However, the challenge lies in extracting meaningful information from the vast amount of collected data. This article focuses on the Fuyu Bridge as a research case and analyzes the variations in environmental factors, such as temperature, humidity, wind load, and structural vibration responses (main beam and cable), obtained from the Fuyu Bridge's structural health monitoring system. It also conducts a structural safety assessment during the operational period of the bridge. Furthermore, the research explores the relationship between environmental factors, load effects, and structural response to establish a foundation for future structural safety assessments of the Fuyu Bridge during its operational period. For instance, changes in environmental factors or load effects can be used to predict structural responses. Additionally, this study provides access to the structural health monitoring data of the Fuyu Bridge, facilitating data‐driven research for other scholars in the field.

AbstractEarly and accurate prediction and simulation of grain crop yield can help maximize the revision and development of regional food policy, which is crucial for ensuring national food security. The development of unmanned aerial vehicle (UAV) technology is gradually gaining an advantage over satellite remote sensing at the field scale. In this study, we predicted maize yield using canopy vegetation indices (VIs) and crop phenology metrics obtained through UAV with ordinary least squares (OLS), stepwise multiple linear regression (SMLR) and gradient‐boosted regression tree (GBRT). The results reveal that the VIs extracted from UAV imagery had a high correlation with yield (R = 0.92), facilitating crop yield estimation. Additionally, coupling crop phenology significantly improved the prediction accuracy of SMLR, with the highest R2 and lowest RMSE of 0.894, 1.238 × 103 kg ha−1, respectively. But, the enhancement of GBRT by this method was slender. Its simulation outperformed OLS and SMLR with dramatic R2, RMSE, and MAE of 0.892, 1.189 × 103 kg ha−1, and 9.150 × 102 kg ha−1, respectively. Moreover, the blister stage was deemed the optimal stage for maize yield prediction with an accuracy rate exceeding 81%. These demonstrated the feasibility of using UAV images to predict crop yields, providing an important reference at the field scale.

AbstractDietary intake is considered as a crucial factor affecting mental health symptoms, particularly depression and anxiety symptoms, especially in the case of pregnant women. This study explored the role of dietary intake in depression and anxiety symptoms of pregnant women and provided evidence for primary care interventions. We enrolled 806 pregnant women in their third trimester from 14 communities in Hengyang City, Hunan Province, China, from July 2019 to September 2019. The Chinese version of the Patient Health Questionnaire‐9 (PHQ‐9) and the Generalized Anxiety Disorder questionnaire‐7 (GAD‐7) were used to assess depression and anxiety symptoms. Dietary intake, demographic characteristics, BMI, and pregnancy characteristics were collected using a self‐designed, structural questionnaire. A covariate‐adjusted logistic regression was conducted to examine the relationship between mental health symptoms and dietary intake. The prevalence of anxiety and depression symptoms in our population were 7.7% (95% CI: 5.9%–9.5%) and 9.2% (95% CI: 7.2%–11.2%), respectively. Women consuming eggs and egg products once a week (OR: 3.688, 95% CI: 1.476–9.215) were more likely to have depression symptom than consumed eggs and egg products once or more per day. Consuming green leafy vegetable <2–3 times per month had a significantly greater risk for depression symptoms than consuming the same once or more per day (OR: 3.450, 95% CI: 1.145–10.393). Women who consumed eggs and egg products 2–3 times a week had an increased likelihood of experiencing anxiety symptoms (OR: 2.253, 95% CI: 1.049–4.837). Anxiety symptoms in women consuming green leafy vegetables <2–3 times per month probably increased by 3.988 times (95% CI: 1.327–11.985) compared with women consuming the same once or more per day. Consuming salted and smoked food <2–3 times per month was protective against anxiety symptoms (OR: 0.181, 95% CI: 0.040–0.828) than consuming the same every day. Implementing interventions to promote healthy dietary among pregnant women is crucial due to its association with mental health. However, future researches are warranted to confirm the reliability and causal association obtained in this study.

AbstractObjectivesDepression may be a risk factor or a prodromal symptom of dementia, and decreased serum levels of brain‐derived neurotrophic factor (BDNF) have been observed in both depression and dementia. The aim of the present study was to determine whether serum levels of BDNF in the remitted or acute phase of depression predicted the transition from depression to dementia.MethodsSerum levels of BDNF were measured in the acute phase of depression (n = 204) and after remission (n = 117), and we followed (mean: 24.3 months) the participants to assess the subsequent onset of dementia or mild cognitive impairment (MCI).ResultsSerum levels of BDNF after remission, but not those in the acute depressive phase, predicted the future development of dementia or MCI.ConclusionsPatients with low serum BDNF levels, even after depression remission, might have an increased risk of developing dementia. These findings suggest a potential association between residual low serum BDNF levels after remission and the prodromal state of dementia, or the involvement of BDNF in the transition from depression to dementia. However, given that this study is low‐powered and preliminary, interpretation of the results should be approached with caution.

Published: September 2023

AbstractThe mechanical properties of polylactide stereocomplexes (PLA SC) have been primarily studied through tensile testing, with inconsistent results, and the compressive properties of PLA SC compared to homocrystalline or amorphous PLA remain poorly understood. In this study, we coated porous bioactive glass 13–93 scaffolds with amorphous, homocrystalline, or stereocomplex PLA to investigate their mechanical and degradation properties before and after immersion in simulated body fluid. The glass scaffolds had interconnected pores and an average porosity of 76%. The PLA coatings, which were 10–100 μm thick and approximately 3% of the glass scaffold mass, covered the glass to a large extent. The compressive strength and toughness of all PLA‐coated scaffolds were significantly higher than those of uncoated scaffolds, with approximately a fourfold increase before immersion and a twofold increase after immersion. The compressive strength and toughness of PLA SC‐coated scaffolds were similar to those of scaffolds with homocrystalline PLA coating, and significantly higher than for scaffolds with amorphous PLA coating. All PLA coatings moderated the initial pH increase caused by the glass, which could benefit surrounding cells and bone tissue in vivo after implantation.
