Gender difference in the relationship between academic self‐efficacy, personal growth initiative, and engagement among Turkish undergraduates: A multigroup modeling
Authors: Gülşen Fatma Uslu , Şahin Ezgi Ekin 
Published: May 2023

AbstractThis study examines the mediating role of personal growth initiative in the relationship between academic self‐efficacy and engagement by examining gender differences. The novelty of this study lies in its focus on the mediating role of personal growth initiative and its examination of gender differences in the relationship between academic self‐efficacy and engagement. By examining if there are any differences in the links between the variables based on gender, this research gives important insight into how these factors influence academic life for different student groups. The data was collected from 607 (333 female and 274 male) full‐time undergraduate students. LISREL was used to test the structural model. We tested the hypotheses that academic self‐efficacy is positively associated with student engagement, personal growth initiative mediates the relationship between academic self‐efficacy and student engagement, and whether there is a gender difference in this mediation model. The findings show that personal growth initiative has a partial mediating role in the relationship between academic self‐efficacy and engagement. In addition, there is no difference between gender‐based groups, and the bootstrap analyses support these findings. Gender does not make a difference in the model because college students may evaluate higher education as increasing their future employment opportunities.

Published: May 2023

AbstractNewly developing genomic technologies are an increasingly important part of clinical care and thus, it is not only important to understand the technologies and their limitations, but to also interpret the findings in an actionable fashion. Clinical geneticists and genetic counselors are now an integral part of the clinical team and are able to bridge the complexities of this rapidly changing science between the bedside clinicians and patients. This manuscript reviews the terminology, the current technology, some of the known genetic disorders that result in lung disease, and indications for genetic testing with associated caveats. Because this field is evolving quickly, we also provide links to websites that provide continuously updated information important for integrating genomic technology results into clinical decision‐making.

RationaleLignans have attracted much attention from researchers because of their wide distribution and industrial applications in plants, as well as the remarkable diversity of their biological activities. As the literature has mainly focused on the extraction and identification of monomeric compounds of lignans, most lignans in Dendrobium officinale, a traditional Chinese medicine with a long cultivation history and rich sources, have not been detected using quality control methods. The aim of this study was to identify the lignans in Dactilon officinale.MethodsHigh‐performance liquid chromatography (HPLC) coupled with diode array detection and HPLC multiple‐stage tandem mass spectrometry was used to identify the chemical constituents of D. officinale. Simultaneously, the characteristic chromatograms of D. officinale were established. Additionally, a method was established to determine the content of syringaresinol‐4,4′‐di‐O‐β‐D‐glucoside, syringaresinol‐4‐O‐β‐D‐glucoside and syringaresinol.ResultsThirty‐three lignans, including 17 tetrahydrofuran lignans, two dibenzylbutane lignans, three aryl tetrahydronaphthalene lignans and 11 8‐O‐4′‐neolignans, were tentatively identified from the methanol extract of the stems of D. officinale. This is the first report of 8‐O‐4′‐neolignans from D. officinale. In addition, a total of eight characteristic peaks were marked in characteristic chromatograms, which were identified as lyoniresinol‐9′‐O‐β‐D‐glucoside, syringaresinol‐4,4′‐di‐O‐β‐D‐glucoside, 8‐hydroxy‐syringaresinol‐4‐O‐β‐D‐glucoside, 5,5′‐dimethoxy‐lariciresinol‐4‐O‐β‐D‐glucoside, syringaresinol‐4‐O‐β‐D‐glucoside, 4‐hydroxy‐3,3′,5,5′‐tetramethoxy‐8,4′‐oxyneoligna‐7′‐ene‐9,9′‐diol‐9‐O‐β‐D‐glucoside, 4‐hydroxy‐3,3′,5,5′‐tetramethoxy‐8,4′‐oxyneoligna‐7′‐ene‐9,9′‐diol‐4‐O‐β‐D‐glucoside and syringaresinol.Our results showed that no significant difference occurred in lignan composition among the 99 batches of D. officinale from different sources. However, the peak areas of the lignans of D. officinale planted under simulated wild culture were generally higher than those in greenhouses, and showed an upward trend with the increase in growth years. The average contents of syringaresinol‐4,4′‐di‐O‐β‐D‐glucoside, syringaresinol‐4‐O‐β‐D‐glucoside and syringaresinol were 10.112–179.873, 51.227–222.294 and 6.368–120.341 μg/g, respectively.ConclusionsThis study provided a basis for improving the quality control of D. officinale and could provide references for the identification of lignans in other Dendrobium species.

AbstractIn this study, a simple, sensitive and environmentally friendly method was developed for the determination of water‐soluble rhodium in soil samples. For this purpose, rhodium was preconcentrated/separated by a dispersive solid phase extraction method (dSPE) and determined by an atomic absorption spectrophotometer with flame atomizer, equipped with a slotted quartz tube (SQT‐FAAS). In the dSPE method, a magnetic colloidal gel (magnetic nanofluid) was produced by mixing Fe3O4 based magnetic nanoparticles (MNP), and deep eutectic solvent (DES) obtained from the mixture of choline chloride and phenol (1 : 3). The optimized system showed good linearity in the concentration range of 17–447 μg/kg. While recording a detection limit (LOD) of 4.26 μg/kg, an over 200‐fold improvement in the detection power was obtained based on the comparison of LODs of the developed method and FAAS. Applicability and accuracy of the developed method were validated by spike recovery results that fell in the range of 89–106 %, using the matrix matching method to boost quantification accuracy in the soil samples.

AbstractSpherical shape copper (Cu) doped ZnO nanostructures of various amount (3, 6, 9 and 12 %) were synthesized. The XRD, FTIR, UV‐Visible, HR‐TEM, FESEM, EDS, SAED and XPS were done to understand the structural, optical, morphology and shape of Cu doped ZnO nanostructures. To achieve the best gas reaction, doping concentration was optimized. ZnO and Cu doped ZnO nanostructures were exposed to various oxygenated volatile organic compounds (OVOCs) and found to be more selective towards acetaldehyde sensing. For 50 ppm acetaldehyde gas, temperature study was done at various temperatures (RT, 50, 100, 150, 200 °C) which showed optimal at 100°C for maximal gas response. The response and recovery time was 16.53 and 18.36 seconds for 50 ppm of acetaldehyde gas. The gas sensing study was carried out at different humidity rates (11, 32, 51, 63 and 84 %) using different saturated solutions. 9 % Cu doped ZnO shows maximum response (61.53 %) as compared to pure ZnO and 3, 6 and 12 % Cu doped ZnO. The spherical shape Cu doped ZnO sensing response was increases with increase in concentration of gas from 10 to 300 ppm. Acetaldehyde gas shows enhanced selectivity towards spherical shape Cu doped ZnO sensors as compared to the other OVOCs like acetone, ethyl methyl ketone, methanol, ethanol, n‐propanol, n‐butanol, formaldehyde, acetaldehyde, propionaldehyde and acrolein. The reproducibility of Cu doped ZnO was studied for 50 days. Also, after acetaldehyde gas sensing change in morphology study of sensor was done.

AbstractThe development of a surface enhanced Raman scattering (SERS) substrate capable of sensing the target analyte at low concentration has always been demanding. In this prospective, ZnO−Au quantum dots (QDs) hybrid structure with tunable surface properties and high chemical stability is considered a promising material for SERS applications. Here, a novel ZnO@Au QDs hybrid structures with various amounts of Au QDs (ZnO−Aux QDs, where x=0.2, 0.4, 0.6 and 1.0) was synthesized by employing solvothermal along with electrodeposition approach. The optimized substrate, ZnO@Au QDs (0.6) exhibits excellent SERS sensitivity for the detection of MB up to 1 nM with a good reproducibility. The chemical and compositional analysis show that the surface defects are formed due to the interface interactions which not only promote charge transfer between ZnO nanowires and Au QDs complex but also enhanced the Raman scattering of target analyte. The developed substrate demonstrates excellent SERS uniformity which makes them reliable choice for the detection of multi‐analyte for practical applications.

AbstractIt is very appealing to develop cheap, highly sensitive and efficient metal ion fluorescence sensors as traditional instrument methods are inherently costly and time‐consuming. Carbon dots (CDs) are widely used for sensing metal ions, attributing to their merits of good biocompatibility, low toxicity, easy surface modification and excellent photostability. This article reviewed the research progress of CDs as metal ion sensors in recent years, and studied their modification methods and detection performances. Finally, the challenges and opportunities of CDs as metal ion sensors were also analyzed. This article is expected to provide inspiration and help for researchers focusing on CDs as metal ion sensors.

Published: May 2023

AbstractThree novel isatin‐triazole tethered tetrahydropyridine‐based colorimetric chemosensors were synthesized for selective recognition of Fe3+ ions. Their selectivity and sensitivity were investigated through colorimetric and UV‐Visible studies in a mixed‐aqueous medium (MeOH/H2O (7 : 3, v/v)). The binding stoichiometry of Chemosensor 3‐methyl 1‐phenyl (5S,6R)‐5‐bromo‐6‐(4‐((2,3‐dioxoindolin‐1‐yl)methyl)‐1H‐1,2,3‐triazol‐1‐yl)‐5,6‐dihydropyridine‐1,3(2H)‐dicarboxylate (6 a) was found to be 1 : 1 with the highest binding constant Ka, 8.6×103 M−1. The detection limit of 6 a for Fe3+ ions (0.47 μM) was much lower than the maximum permissible limit of Fe3+ ion according to Environmental Protection Agency (EPA). Moreover, the 6 a‐Fe3+ complex was found to be recyclable upon the addition of EDTA. Furthermore, the reversible colorimetric changes of 6 a on adding Fe3+ ions and EDTA were found to mimic the ‘INHIBIT’ molecular logic gate. The chemosensor 6 a recognizes Fe3+ ions by binding through oxygen atoms of isatin as confirmed by Density Functional Theory (DFT) studies.

Published: May 2023

AbstractThe present study reports a comparative analysis of the antioxidant potential of the aqueous and ethanolic extracts of Phyllanthus fraternus leaves. The reducing power and total polyphenolic content of the extracts were also measured. A significant correlation (0.99) was found between total antioxidant activity and the polyphenolic content of the extract. Ultra‐performance liquid chromatography/quadrupole‐time‐of‐flight mass spectrometry (UPLC/Q‐TOF‐MS) analysis resulted in the identification of twenty bioactive compounds from the aqueous extract of leaves. These compounds have been identified for the first time in the P. fraternus extract. The hepatoprotective activity of the compounds was assessed through in silico docking analysis against two important liver enzymes, alanine aminotransaminase (ALT) and aspartate aminotransaminase (AST). Seven hepatoprotective compounds‐ hinokitiol, daidzein, gamma‐tocopherol, luteolin, hesperitin, scoulerin, and 7‐hydroxy‐4‐methylcoumarin have been identified that could be used in hepatoprotective drug formulations after clinical trials.

Published: May 2023

AbstractCerium and boron are commonly used components to tune the acidic/basic property of catalysts in industry. In this work, cerium or boron‐doped copper‐based catalysts (xM−Cu/SiO2, M=Ce/B) were prepared with the ammonia‐evaporation method. Both X‐ray diffraction and Auger electron spectroscopy revealed that Cu+ content increased along with the Ce‐doping, but decreased by B‐doping. NH3‐Temperature Program Desorption results showed no change in the acidity of Ce‐doped catalysts, while significant amounts of medium‐strong acid sites appeared after B‐doping. Application in ethylene carbonate hydrogenation indicates the promoting role of Ce‐dopant in methanol production, while boron exhibits negative effects. The significant difference can be attributed to distinctive acidic/basic properties of Ce/B dopants, which affect the interaction between Cu and Si in the precursors, and thus adjust the ratio of Cu+/(Cu++Cu0).

AbstractIt is great significance to explore rich and efficient transition metal‐based electrocatalysts for the electrolysis of water. Nickel‐molybdenum (Ni−Mo) alloy is considering as one of the most promising electrocatalysts for hydrogen evolution reactions (HER) in alkaline electrolyte, but its catalytic performance for oxygen evolution reaction (OER) is still unsatisfactory. Heteroatom doping by interfering with the electronic structure of the catalysts has been considered to be an effective method to enhance electrocatalytic activities. Herein, we report the synthesis of iron (Fe)‐doped Ni4Mo intermetallic compound with hierarchical nanorod assemblies on nickel foam by hydrothermal and hydrogen‐induced methods, which significantly improve the catalytic performance for OER. The as‐prepared Fe−Ni4Mo/NF shows remarkable activity for alkaline oxygen evolution reaction, requiring only a low overpotential of 271 mV to achieve a current density of 100 mA cm−2. Such performance is significantly better than that of pristine Ni4Mo/NF with overpotential of 400 mV. Density functional theory (DFT) calculation shows that the addition of Fe can significantly reduce the adsorption energy of the intermediate on the catalyst surface, thus facilitating the OER activity. Moreover, an alkaline electrolyzer composed of Fe−Ni4Mo/NF as cathode and anode can provide 10 mA cm−2 current density with only 1.48 V extremely low voltage, and shows excellent long‐term durability of 24 h. These results highlight a heteroatom incorporation engineering strategy into metallic alloys for electrochemical applications.

Published: May 2023

AbstractGraphene oxide (GO) based nano‐formulation has gained much attention because of its carbonaceous composition with biologically benign properties. In this study, the interactions of GO with tacrine (TAC), an FDA approved Alzheimer's disease (AD) drug, are explored using various analytical tools and theoretical modeling techniques. Furthermore, the modulatory effect of these nano‐conjugates toward the in‐vitro catalytic activity of the neurodegenerative enzyme acetylcholinesterase (AChE) is also quantified. The maximal rate for enzyme inhibition in presence of the nanoconjugate decreases up to an extent of 16 and 34 % in comparison with TAC and GO, respectively. Interestingly, these results are in sharp contrast to the increased AChE activity on adsorption into spherical gold and silver nanoparticles. The current findings demonstrate the synergistic use of TAC−GO hybrid material with augmented AChE inhibition efficacy towards the treatment of Alzheimer's disease (AD). Additionally, GO presents a sustainable alternative for biomedical applications to inorganic equivalents.
Who gains and who loses from more information in technology markets? Evidence from the Sunshine Act
Authors: Zhang Huiyan , Branstetter Lee , Conti Raffaele , Mamadehussene Samir 
Published: May 2023

AbstractResearch SummaryWe consider the context of a technology market where participants (in particular, sellers) differ in reputation, and sellers observed participating in the transactions might suffer a reputation loss. Our theoretical model predicts that low‐reputation idea sellers, thanks to the improvement in information disclosure, are more likely to be involved in technology transactions; at the same time, high‐reputation idea sellers, to protect their reputations, might prefer avoiding any transactions. This shift in seller composition might affect the quantity and quality of collaborations. To test our theory, we assess the effect of the Physician Payment Sunshine Act on physician‐firm collaborations. Overall, our findings indicate that while information disclosure might benefit some market participants, it can have unintended negative consequences for others.Managerial SummaryIn technology markets, more information about market participants generally leads to better outcomes. However, in contexts where sellers suffer a reputation loss if their transactions become known, higher‐reputation sellers may leave the market, affecting the quality of ideas being traded and impacting buyers. On the other hand, lower‐reputation sellers may benefit from increased visibility and share their ideas more frequently. Our research examined these effects in the context of the Physician Payment Sunshine Act, which made physician collaborations with medical device companies visible. The results suggest that the effects of information disclosure are not uniform and that some market participants may benefit while others may suffer losses.
Switching between 3D Surface Topographies in Liquid Crystal Elastomer Coatings Using Two‐Step Imprint Lithography

Published: May 2023

AbstractWhile dynamic surface topographies are fabricated using liquid crystal (LC) polymers, switching between two distinct 3D topographies remains challenging. In this work, two switchable 3D surface topographies are created in LC elastomer (LCE) coatings using a two‐step imprint lithography process. A first imprinting creates a surface microstructure on the LCE coating which is polymerized by a base catalyzed partial thiol‐acrylate crosslinking step. The structured coating is then imprinted with a second mold to program the second topography, which is subsequently fully polymerized by light. The resulting LCE coatings display reversible surface switching between the two programmed 3D states. By varying the molds used during the two imprinting steps, diverse dynamic topographies can be achieved. For example, by using grating and rough molds sequentially, switchable surface topographies between a random scatterer and an ordered diffractor are achieved. Additionally, by using negative and positive triangular prism molds consecutively, dynamic surface topographies switching between two 3D structural states are achieved, driven by differential order/disorder transitions in the different areas of the film. It is anticipated that this platform of dynamic 3D topological switching can be used for many applications, including antifouling and biomedical surfaces, switchable friction elements, tunable optics, and beyond.
