Læreres forståelser af bidrag til elevers dannelse i undervisning med litteraturlæremidler på mellemtrinnet
Authors: Oksbjerg Marianne 
Published: April 2022

ResuméNyere forskning peger på, at didaktiske litteraturlæremidler spiller en central rolle for læreres undervisningspraksis i skolens danskfag. Der mangler imidlertid forskning i, hvilke forestillinger dansklærere har om elevers dannelse i undervisning, hvor didaktiske læremidler inddrages. I artiklen belyses dette område gennem analyser af interviews med fire lærere, som underviser på mellemtrinnet. For to af lærernes vedkommende peger resultaterne på, at deres egen forståelse af undervisningens dannelsesbidrag på centrale områder afviger fra den forståelse, der implicit ligger i det valgte læremiddel. Et resultat er desuden, at lærerne ikke selv ser denne diskrepans.
Abstract (UK)Recent research indicates that didactical learning resources play an essential role in teachers practice in literature teaching in primary education, but research focusing on teachers understanding of students Bildung when they involve didactical learning resources in classroom teaching is rarely seen. This article analyzes interviews with four teachers who are involving didactical learning resources in literature teaching for grade 5 and 6. The interviews show that two of the teachers tend to understand students Bildung in a significantly different way than the understanding represented in the learning resources. Furthermore, it is notable that the teachers themselves are not aware of this discrepancy.

Published: April 2022

Aims: Gas diffusion layer (GDL), catalytic layer (CL) and proton exchange membrane (PEM) are important components of hydrogen fuel cell (HFC). In this paper, the thickness of the diffusion layer, the catalytic layer and the proton exchange membrane of the hydrogen fuel cell are mainly simulated and analyzed, and the structural parameters with relatively good performance of the hydrogen fuel cell are obtained.
Place and Duration of Study: North China University of Water Resources and Electric Power, Zhengzhou, Henan Province, between November 2021 and March 2022.
Methodology: Fuel cell models with different diffusion layers, catalytic layers and proton exchange membrane thicknesses were established by ANSYS, and simulated and analyzed them in the PEMFC module in Fluent, comparing the temperature distribution, water distribution and current density distribution of HFC with diffusion layer thickness, catalytic layer thickness and proton exchange membrane thickness, and comparing the structural parameters with relatively good performance of hydrogen fuel cells.
Conclusion: The results show that the thicker the diffusion layer is, the more unfavorable the product water is discharged, which hinders the diffusion of oxygen and reduces the performance of fuel cell; The larger the thickness of the catalytic layer, the higher the current density and the better the performance of the hydrogen fuel cell; The larger the thickness of proton exchange membrane, the negative effect on the diffusion of reactive gas, the lower the reaction efficiency and current density of fuel cell, and the lower the performance of fuel cell.

Authors: Keerthana T. , Ramesh Sindhu 
Published: April 2022

Introduction: Recognition of variations in molar root morphology is critically important for dental procedures such as root canal treatment and apical surgery. Usage of CBCT enables systemic evaluation of teeth including the number of roots and canals, location of roots, etc. The aim of this study was to determine the frequency of multiple canals in mandibular first and second premolars and to evaluate correlations between other anatomical variants using Cone beam computed tomography (CBCT).
Methodology: The protocol of this retrospective, cross-sectional study was approved by the Ethics Committee of Saveetha Dental Hospital, Chennai, India. Images of mandibular premolars were obtained from patients who had undergone CBCT scanning at the hospital between January 2018 and November 2020.Cross-sectional images in the axial, coronal, and sagittal planes were reconstructed using GALILEOS ComfortPLUS ( Sirona 3D)is an advanced CBCT that provides seamless workflow integration. Serial axial, coronal and sagittal-plane CBCT images were closely examined at 1.0-mm intervals from the canal orifice to the apex.
Results: Using SPSS software (ver. 21; SPSS, Inc., Chicago, IL, USA), chi-squared test was performed for analyses of different parameters involved. Various anatomical variants such as distolingual roots of first molars, C shaped canals of second molars are highly correlated with different canal configurations of mandibular premolars.
Conclusion: This retrospective study showed that different configurations of mandibular premolars canals was significantly correlated with the presence of Distolingual root (DLRs) in first molars, and C shaped canals in second molars. Understanding and identifying anatomical variants is important in comprehensive success of endodontic treatment.
Combined Experimental and DFT Study on 2D MoSe2 toward Low Infrared Emissivity
Authors: Wu Wei , Tong Liping , Zhou Han , Fan Tongxiang 
Published: April 2022

AbstractLow infrared emissivity materials play a key role in thermal camouflage or retardation. Among these, fillers can be easily shaped into various flexible forms and normally provide an omnidirectional and polarization‐insensitive emissivity. However, conventional fillers suffer from drawbacks of full‐waveband ultrahigh reflectivity, unsatisfactory thermal camouflage performances, or poor chemical/thermal stabilities. Herein, 2D MoSe2 is discovered as a new semiconductor with intrinsic low infrared emissivity after first‐principle density functional theory calculation and experimental demonstration on eight types of two‐dimensional materials (2DMs). Mechanisms of electron–photon reflection and phonon–photon absorption for the low infrared emissivity are proposed. A two‐step microwave‐assisted amination process is developed to exfoliate the nanosheets and obtain a desired low infrared emissivity. The as‐obtained chitosan modified MoSe2 (CS@MoSe2) has an ultrahigh spectral reflectivity of 78%–86% in 8–14 µm, and its resin‐based coating still exhibits a low infrared emissivity of 0.32 and shows a dramatic reduction in radiation temperature of 28 °C for a hot object at 70 °C. Besides, CS@MoSe2 can endure a high temperature of 220 °C and is demonstrated with a long‐term thermal camouflage efficiency in hot environments. This work will guide 2DMs selection and preparation toward desired infrared radiation properties to satisfy numerous applications.

Published: April 2022

AbstractStrain in layered transition‐metal dichalcogenides (TMDs) is a type of effective approach to enhance the catalytic performance by activating their inert basal plane. However, compared with traditional uniaxial strain, the influence of biaxial strain and the TMD layer number on the local electronic configuration remains unexplored. Herein, via a new in situ self‐vulcanization strategy, biaxially strained MoS2 nanoshells in the form of a single‐crystalline Ni3S2@MoS2 core–shell heterostructure are realized, where the MoS2 layer is precisely controlled between the 1 and 5 layers. In particular, an electrode with the bilayer MoS2 nanoshells shows a remarkable hydrogen evolution reaction activity with a small overpotential of 78.1 mV at 10 mA cm‐2, and negligible activity degradation after durability testing. Density functional theory calculations reveal the contribution of the optimized biaxial strain together with the induced sulfur vacancies and identify the origin of superior catalytic sites in these biaxially strained MoS2 nanoshells. This work highlights the importance of the atomic‐scale layer number and multiaxial strain in unlocking the potential of 2D TMD electrocatalysts.

AbstractA copper‐catalyzed cross‐dehydrogenative coupling (CDC) reaction between aromatic aldehydes and DMSO was developed, which afforded β‐keto sulfoxides in 73–92% yields. The reaction process involved base‐promoted DMSO addition to aldehydes, and copper‐catalyzed aerobic oxidation. Furthermore, the aromatic alcohols which could be oxidized to aldehydes are also suitable substrates for this catalytic system.magnified image
Sponge‐Like Nickel Carbonate of High Porosity and Carbonate Vacancy for High‐Performance CO2 Photoreduction

Published: April 2022

AbstractAs most of the fossil carbon on earth is stored in an oxidized state as carbonate minerals, exploration of metal carbonate catalyst for selective CO2 reduction can open appealing access to boost the CO2 capture and storage. However, carbonate is commonly regarded as a poor matrix to host photocatalytic active species, and current literature has few reports of carbonate‐based photocatalytic material. Herein, a hierarchically porous catalyst that features ≈5 nm deficient NiCO3 nanoparticles embedded in sponge‐like high‐magnesium calcite is disclosed. In the photocatalytic CO2 reduction reaction, the as‐prepared catalyst of low Ni content attains a high CO production rate of 10 565 µmol g−1 h−1 and a high selectivity of 94% relative to H2 evolution, a performance that surpasses many other state‐of‐the‐art nickel‐based catalysts. Experiments and theoretical calculations reveal that the carbonate vacancy of NiCO3 strengthens the adsorption and activation of CO2 more significantly than the corresponding oxygen vacancy of NiO. The inert CO2 molecule becomes highly deformed on the surface of NiCO3 which can be readily activated to the key intermediate CO2·− for the photoreduction reaction. The present findings add to the existing knowledge of advanced catalysis using defect materials and demonstrate an intriguing and rare case of highly performing carbonate‐based catalyst.

Published: April 2022

AbstractDevelopment of efficient nanotherapeutic agents to enhance anticancer therapeutic effects is challenging. In this study, photo/sono‐dual‐responsive boron imidazolate framework‐derived single‐component porous carbon nanospheres (PCNSs) are successfully developed for dual‐mode bioimaging‐guided photothermal/sonodynamic (PTT/SDT) synergistic therapy for triple‐negative breast cancer. The PCNS not only exhibits satisfactory and excellent photothermal conversion ability under near‐infrared laser irradiation but also demonstrates a promising capability as an efficient sonosensitizer to generate cytotoxic reactive oxygen species through inertial cavitation in response to low‐intensity ultrasound stimulation. The outstanding photothermal effect enhances the blood flow in tumor tissues and thus improves the oxygen supply, helping to achieve a remarkable synergistic therapeutic effect in the PTT/SDT synergistic therapy without any tumor recurrence or systemic toxicity. Interestingly, the PCNS enables the precise visualization of solid tumors using contrast‐enhanced ultrasound and photothermal dual‐modal bioimaging techniques. Overall, this study provides valuable insights in developing all‐in‐one theranostic nanoplatforms for the clinical treatment of triple‐negative breast cancer.

Published: April 2022

Abstract2D materials have shown great potential in the application of resistive random access memory (RRAM) for information storage. Much attention has been attracted from 2D semiconducting bismuth oxyselenide (Bi2O2Se) for excellent properties in multi‐performance nanoelectronics. By using a chemical vapor deposition (CVD) method, Bi2O2Se nanosheets with high quality are grown. Combining with the oxygen plasma method, 2D heterostructure of Bi2O2Se/Bi2SeOx nanosheet is realized; and the heterostructure exhibits obvious resistive switching behavior. The resistive switching mechanism is analyzed in detail, and the conductive mechanism of the fabricated device is also discussed. The resistive switching of Bi2O2Se nanosheets is endowed through the method of O2 plasma treatment, which makes it feasible for developing its application in the RRAM.
Food insecurity and time use in elderly vs. non‐elderly: An exploratory analysis
Authors: Berning Joshua , Cleary Rebecca , Bonanno Alessandro 
Published: April 2022

AbstractIn the US, elderly households are more food secure than younger households. A possible explanation is that increased time availability enables elderly households to adopt strategies to improve their food security. Using time use data, we find elderly households spend more time in meal preparation and eating time than younger households. Creating a matched dataset of household time use and food security, we find that meal preparation and eating time have a small contribution to differences in food insecurity between older and younger households. However, these relationships are heterogeneous depending upon marital status and age cohort of the household head.
Prescribed defoliation strategies influence soil carbon and nitrous oxide potential in pastures
Authors: Kelly Charlene N. , Koos Jordan , Griggs Thomas , Freedman Zachary B. 
Published: April 2022

AbstractCool‐season perennial grasslands are commonly used for livestock pasture. However, understanding of the belowground effects of forage defoliation (selective pressure applied by grazing) management is nascent. We investigated how defoliation management affects aboveground (forage productivity) and belowground processes (soil C/N), microbial nutrient cycling, and potential nitrous oxide [N2O] emissions). We hypothesized that rotational (moderate frequency) defoliation at low severity will increase soil organic matter (SOM) storage and microbial capacity to cycle C, N, and P, but that these changes would also lead to greater soil N2O emission potential. Data were collected from organically (OF) and conventionally managed (CF) farms with differing botanical composition in West Virginia, where three frequencies and two severities of forage defoliation were imposed. At OF, more severe defoliation decreased labile soil C content (–26%), while moderate defoliation resulted in a 39% reduction in microbial enzymatic capacity to cycle C, but not at CF. The N2O emission potential (ratio of nirK/nosZ functional gene abundance), was differentially affected by defoliation treatments at both sites. At OF, defoliation severity altered N2O emission potential, whereby low severity resulted in an 82% decrease in potential N2O emissions compared with high severity treatments. At CF, continuously defoliated plots exhibited a 71% lower N2O emission potential relative to less frequent defoliation. Belowground microbial parameters were more responsive to defoliation at OF, suggesting past management may influence how grazing management asserts belowground changes. Results suggest that defoliation management could enhance soil C storage, but potentially at the risk of increased N2O emissions.
