Published: September 2024

AbstractCovalent organic frameworks (COFs) have emerged as one of the most studied photocatalysts owing to their adjustable structure and bandgaps. However, there is limited research on regulating the light‐harvesting capabilities of acceptor building blocks in donor–acceptor (D–A) isomer COFs with different bond orientations. This investigation is crucial for elucidating the structure‐property‐performance relationship of COF photocatalysts. Herein, a series of D–A isostructural COFs are synthesized with different imine bond orientations using benzothiadiazole and its derivatives‐based organic building units. Extended light absorption is achieved in COFs with acceptor groups that have strong electron‐withdrawing capacities, although this resulted a decreased hydrogen generation efficiency. Photocatalytic experiments indicated that dialdehyde benzothiadiazole‐based COFs, HIAM‐0015, exhibit the highest hydrogen generation rate (17.99 mmol g−1 h−1), which is 15 times higher than its isomer. The excellent photocatalytic performance of HIAM‐0015 can be attributed to its fast charge separation and migration. This work provides insights into the rational design and synthesis of D–A COFs to achieve efficient photocatalytic activity.

AbstractDue to the low stability and high cost of some natural enzymes, nanozymes have been developed as enzyme‐imitating nanomaterials. Single‐atom nanozymes are a class of nanozymes with metal centers that mimic the structure of metal‐based natural enzymes. Herein, Cu‐N‐C single‐atom nanozyme (SAN) is synthesized with excellent peroxidase‐ and enhanced oxidase‐like activities to mimic the action of natural galactose oxidase. Cu‐SAN demonstrates stereospecific activity akin to that of natural galactose oxidase by oxidizing D‐galactose and primary alcohol but not L‐Galactose or other carbohydrates. The SAN can catalyze the oxidation of galactose in the presence of oxygen, producing hydrogen peroxide as a sub‐product. The produced hydrogen peroxide then oxidizes 3,3′,5,5′‐tetramethylbenzidine catalyzed by the SAN, yielding the typical blue product. The relationship between absorbance and galactose concentration is linear in the 1–60 µm range with a detection limit as low as 0.23 µm. This strategy can be utilized in the diagnosis of galactosemia disorder and detection of galactose in some dairy and other commercial products. DFT calculations clarify the high activity of the Cu sites in the POD‐like reaction and explain the selectivity of the Cu‐SAN oxidase‐like reaction toward D‐galactose
Room‐Temperature Possible Current‐Induced Transition in Ca2RuO4 Thin Films Grown Through Intercalation‐Like Cation Diffusion in the A2BO4 Ruddlesden–Popper Structure

Published: September 2024

AbstractCation deficiency tuning is a central issue in thin‐film epitaxy of functional metal oxides, as it is typically more difficult than anion deficiency tuning, as anions can be readily supplied from gas sources. Here, highly effective internal deficiency compensation of Ru cations is demonstrated for Ca2RuO4 epitaxial films based on diffusive transfer of metal cations in the A2BO4 Ruddlesden–Popper lattice from solid‐phase cation sources. Through detailed structural characterization of Ca2RuO4/LaAlO3 (001) thin films grown with external cation sources by solid‐phase epitaxy, the occurrence of intercalation‐like, interstitial diffusion of La cations (from the substrates) in the A2BO4 structure is revealed, and that of Ru cations is also suggested. Relying on the interstitial‐type diffusion, an optimized Ru deficiency compensation method, which does not induce the formation of Can+1RunO3n+1 Ruddlesden–Popper impurity phases with higher n, is proposed for Ca2RuO4 epitaxial films. In the Ca2RuO4/LaAlO3 (001) thin films grown with Ru deficiency compensation, record‐high resistivity values (102–10−1 Ω cm) and a large (more than 200 K) increase in the temperature range of the nonlinear transport properties are demonstrated by transport measurements, demonstrating the possible advantages of this method in the control of the current‐induced quantum phase transition of Ca2RuO4.

AbstractFor group 14 mono‐elemental 2D materials, such as silicene, germanene, and stanene, oxidation is a severe problem that alters or degrades their physical properties. This study shows that the oxidized germanene on Ag(111)/Ge(111) can be reformed to germanene by simple heating ≈500 °C in a vacuum. The key reaction in reforming germanene is the desorption of GeO and GeO2 during heating ≈350 °C. After removing surface oxygen, Ge further segregates to the surface, resulting in the reformation of germanene. The reformed germanene has the same crystal structure, a (7√7 × 7√7) R19.1° supercell with respect to Ag(111), and has equivalent high quality to that of as‐grown germanene on Ag(111)/Ge(111). Even after air oxidation, germanene can be reformed by annealing in a vacuum. On the other hand, the desorption of GeO and GeO2 at high temperatures is not suppressed in the O2 backfilling atmosphere. This instability of oxidized germanene/Ag(111)/Ge(111) at high temperatures contributes to the ease of germanene reformation without residual oxygen. In other words, the present germanene reformation, as well as the segregation of germanene on Ag(111)/Ge(111), is a highly robust process to synthesize germanene.

Published: September 2024

AbstractTitanium alloys have been widely used in marine engineering fields. However, because of high biocompatibility, they are vulnerable to biofouling. In this work, based on the micro‐arc oxidation technology and spontaneous galvanic replacement reaction, a temperature‐responsive low‐toxic smart coating consisting of liquid metal particles is designed to control the release of Ga3+, Cu2+, and Cu1+ ions in different temperatures. This technology can ensure the full release of active ingredients within the target temperature range, intelligently maintaining the excellent anti‐biofouling performance, while saving active ingredients. After being immersed in culture media with Sulfate‐Reducing Bacteria (SRB) for 14 days at 10, 20, and 30 °C, at the optimal activity temperature of 30 °C for SRB, the best sample releases the highest amounts of Ga3+, Cu2+, and Cu1+ ions, demonstrating a 99.9% bactericidal rate. When the temperature decreases to 10 °C, the activity level of SRB is very low, and the smart coating can also reduce the released ions correspondingly, still with a 97.3% bactericidal rate. The remarkable anti‐biofouling performance is attributed to the physical damage and lethal ions interaction. Furthermore, the best sample exhibits good corrosion resistance. This work presents a design route for smart anti‐biofouling coatings for temperature‐responsive.

AbstractThe rational construction of a hierarchical noble metal–metal‐organic frameworks (MOFs) structure is anticipated to yield enduring and highly efficient performance in alkaline electrocatalytic water splitting. Herein, a sandwich construction strategy is employed to enhance the stability, wherein active RutheniRu (Ru) nanosheets are incorporated onto nickel foam (NF) and subsequently covered with porphyrinic MOFs (PMOFs). In addition, activated PMOF‐NiOOH‐Ru20/NF‐C/A electrodes are obtained by electrochemical self‐reconstruction as cathode and anode, respectively. Density functional theory (DFT) calculations demonstrated that the resulting PMOF‐NiOOH‐Ru heterointerface effectively facilitated electron transfer, enhanced H2O adsorption capacity, and optimized ΔG values for *H and *O to *OOH. Consequently, PMOF‐NiOOH‐Ru20/NF‐C/A exhibited low overpotentials for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), accompanied by minimal Ru leakage. Furthermore, stable overall water splitting can be achieved with a low voltage of 1.456 V@10 mA cm−2 for over 120 h. Even when operated in simulated seawater, the prepared electrodes demonstrated similar activity and stability. This study contributes to a deeper understanding of the regulation mechanism for the performance and stability of active sites in the electrocatalytic self‐reconstruction process.

AbstractGiven the scientifically significant importance of studying the chirality of clusters, the challenges of synthesizing chiral clusters are progressively surmounted. However, the racemization of clusters is unavoidable, and it limits the development of their follow‐on chiral applications. To address this issue, chiral thiols are synthesized and used for the construction of high‐stability optically pure nanoclusters in this work. As a result, a pair of chiral nanoclusters, Au24Cd2(SR)14, is obtained with excellent stability under thermal, acidic, alkaline, oxidizing, and reducing environments. Unexpectedly, it can also maintain its optical activity with the introduction of Cu2+ ions and chiral ligand with opposite configuration. Structural relationship analysis indicates that the excellent stability is mainly dependent on the hierarchical assembly of the nanoclusters, in which the chiral assembly of chiral ligands (a new pattern of chiral arrangement of intramolecular ligands on the surface of clusters) may be a key factor.
Exploring the corruption‐inefficiency nexus using an endogenous stochastic frontier analysis
Authors: Finocchiaro Castro Massimo , Guccio Calogero 
Published: September 2024

AbstractSeveral scholars report that, due to reverse causality, the endogeneity problem makes it difficult to identify the real effect of institutional factors at the local level, such as corruption, on firm efficiency. This study employs a panel stochastic frontier analysis that endogenizes production efficiency and robustly assesses the effect of corruption at the local level on firms' technical efficiency. We analyze a large panel of Italian firms operating in the building sector from 2013 to 2019 showing that the determinants of local institutional quality affects firms' performance, with the rule of law and control of corruption playing a preeminent role. Controlling for endogeneity, the magnitude of the effects of institutional quality factors at the local level significantly increase. Our findings are robust to alternative IV strategies, alternative specifications of the production function, and the inclusion of other factors that may affect firm efficiency.
Effect of the Ratio of Soluble and Insoluble Dietary Fiber from Rice Bran with Extrusion Cooking Treatment on Pasting, Thermal, and Structural Properties of Rice Starch Gel

Published: September 2024

AbstractThis study aims to investigate the effect of different ratios of soluble and insoluble dietary fiber (0/100, 25/75, 40/60, 55/45, 70/30, 85/15, 100/0) in rice bran treated with or without extrusion cooking on the physicochemical and structural properties of rice starch. As the ratio of soluble dietary fiber (SDF) increases, the PV (peak viscosity), FV (final viscosity), SB (setback value), and BD (breakdown value) of starch are significantly decreased, indicating that a higher SDF ratio can delay the short‐term retrogradation of starch. Compared with the unextruded rice bran SDF/IDF starch gel, the content of weak bond water and free water in the extruded rice bran SDF/IDF starch gel is higher while the content of strong bond water in the starch gel is lower at the same SDF/IDF ratio. Meanwhile, for the results X‐ray diffraction (XRD) and fourier transform infrared spectrum (FTIR), the rice starch with the extruded rice bran SDF/IDF ratio of 25:75 shows the lowest relative crystallinity of 3.48% and the lowest peak to height ratio of FTIR (1047 cm−1/1022 cm−1) of 1.0746, suggesting that the inhibition effect on rice starch retrogradation is better. This may be beneficial for the utilization of different ratios of SDF/IDF from extruded rice bran and physicochemical properties improvement of rice starch gel.

AbstractIntroductionAlthough increasingly appreciated, little is known about the prevalence of fecal urgency, fecal incontinence and differences between patients' and physicians' perception in inflammatory bowel disease (IBD).MethodsWe performed an online patient and physician survey to evaluate the assessment, prevalence and impact of fecal urgency and incontinence in IBD.ResultsA total of 593 patients (44.0% ulcerative colitis (UC), 53.5% Crohn's disease (CD), 2.2% indeterminate colitis, 2 not specified) completed the survey (65.8% females, mean age 47.1 years). Fecal urgency was often reported (UC: 98.5%, CD: 96.2%) and was prevalent even during remission (UC: 65.9%, CD: 68.5%). Fecal urgency considerably impacted daily activities (visual analog scale [VAS] 5, IQR 3–8). Yet, 22.8% of patients have never discussed fecal urgency with their physicians. Fecal incontinence was experienced by 44.7% of patients and 7.9% on a weekly basis. Diapers/pads were required at least once a month in 20.4% of patients. However, 29.7% of patients never talked with their physician about fecal incontinence. UC was an independent predictor for the presence of moderate‐severe fecal urgency (OR 1.65, 95% CI 1.13–2.41) and fecal incontinence (OR 1.77, 95% CI 1.22–2.59). All physicians claimed to regularly inquire about fecal urgency and incontinence. However, the impact of these symptoms on daily activities was overestimated compared with the patient feedback (median VAS 8 vs. 5, p = 0.0113, and 9 vs. 5, p = 0.0187).ConclusionsFecal urgency and incontinence are burdensome symptoms in IBD, with a similar prevalence in UC and CD. A mismatch was found between the physician and patient perception. These symptoms should be addressed during outpatient visits.
Demonstrating a decision support process for landscape conservation design

Published: September 2024

AbstractDespite the recent increase in landscape conservation and the design processes agencies are undertaking, there remains an implementation gap due to an inability to evaluate general strategies and account for uncertainties faced by managers. We demonstrated how a decision support process (DSP), recently developed to inform landscape conservation design, can address uncertainties and complexities inherent in landscape conservation to facilitate long‐term, large‐scale conservation planning. We applied the DSP to landscape conservation efforts within conservation opportunity areas (COA) of states in the Gulf Coastal Plains and Ozarks region. We engaged state planners within the region to identify important landscape conservation uncertainties they face in planning. We developed, simulated, and modeled the impacts of conservation addressing 3 uncertainties identified by state wildlife managers and evaluated the impacts by examining the responses of state and local populations of 2 bird species of conservation concern, prairie warbler (Setophaga discolor) and wood thrush (Hylocichla mustelina). The responses of prairie warbler populations to conservation strategies indicated that both approaches of protecting quality habitat from land‐use change and restoring and enhancing lower quality and nonhabitat improved their viability at regional, statewide, and COA scales. However, we noted that the relative effectiveness of strategies varied among states in ways that suggest a state's process for delineating COAs and what threats they face could influence which conservation approach to consider. Our findings highlight the need for regional coordination and the use of decision‐support processes to guide effective conservation at landscape scales.

Lerndialoge und Lernunterstützung: Die Rolle der Lehrperson beim sozial-konstruktivistischen Wissensaufbau
Authors: Tanner Iris 
Published: September 2024

ZusammenfassungIn diesem Kapitel wird auf zentrale theoretische Grundannahmen zur Unterstützungsrolle der Lehrperson im Unterricht genauer eingegangen. Die Aufgabe der Lehrperson besteht darin, Problemsituationen aufzuzeigen, so dass bei den Lernenden kognitive Konflikte entstehen. Dann unterstützen sie diese beim «aktiven Vollzug der Erkenntnisakte» (Pauli, 2006, S. 197). Die Bedeutung des Lerndialoges (vgl. Abschnitt 3.1) wird beschrieben, der eine fachlich-fachdidaktische Seite und eine emotional-motivationale Seite der Lernunterstützung umfasst. In Bezug auf die fachdidaktische Seite (vgl. Abschnitt 3.2) wird u.a. der Modellierungsprozess tiefer vorgestellt, der zum Lösen von Textaufgaben durchlaufen werden muss. Dann wird auf die kommunikativen Anforderungen von Lehr-Lerndialogen eingegangen (vgl. Abschnitt 3.3). Zu diesem Teilaspekt sind besonders die Konzepte von Beteiligungsrahmen zentral, die den Schülern und Schülerinnen in Lehr-Lerngesprächen gegeben werden sollen. Diese können u.a. durch eine lernförderliche Gesprächsführung eingebracht werden.

AbstractIn 1939 Turán raised the question about lower estimations of the maximum norm of the derivatives of a polynomial p of maximum norm 1 on the compact set K of the complex plain under the normalization condition that the zeroes of p in question all lie in K. Turán studied the problem for the interval I and the unit disk D and found that with $$n:= \deg p$$

tending to infinity, the precise growth order of the minimal possible derivative norm (oscillation order) is $$\sqrt{n}$$

for I and n for D. Erőd continued the work of Turán considering other domains. Finally, in 2006, Halász and Révész proved that the growth of the minimal possible maximal norm of the derivative is of order n for all compact convex domains. Although Turán himself gave comments about the above oscillation question in $$L^q$$
