A critical approach to the evaluation of the quality of accounting research in the Spanish university systand its implications
Authors: Argilés-Bosch Josep M. , Garcia-Blandon Josep , Ravenda Diego 
Published: January 2023

This research analyses the convenience and consequences of the ANECA criteria for the assessment of the research performed by accounting academics in Spain. We focus on the level for the accreditation of catedrático de universidad, and the publication patterns and possibilities of the accounting scholars in Spain. We find that they have more difficulties for publication than their counterparts in adjacent fields of knowledge. Most of the accounting academics affiliated to Spanish institutions than have succeeded in publishing in the top international accounting journals co-authored their articles with foreign authors, mainly affiliated to USA or UK institutions, and/or focused their research on international setting and topics. The Spanish regulation for accreditation stresses this pattern. This situation may have serious consequences for the survival of the accounting discipline in Spain and for the research on topics focused on Spanish problems.
Este trabajo analiza la conveniencia y consecuencias de los criterios de evaluación de la actividad investigadora en contabilidad establecidos por ANECA, concretándonos en los criterios para la acreditación de catedrático de universidad, así como el patrón y posibilidades de publicación de los académicos contables en España, Europa y a nivel mundial. Encontramos que los académicos del área contable tienen unas dificultades para publicar que son substancialmente superiores a las de los académicos de otras áreas de empresa. La mayor parte de los académicos afiliados a instituciones españolas que consiguen publicar en las principales revistas académicas contables recurren a co-autorías, principalmente estadounidenses y británicas, y a focalizar el contenido de sus trabajos en contextos y problemáticas no españolas. La normativa española de acreditación acentúa este comportamiento. Esta situación puede tener graves implicaciones para la supervivencia del área de conocimiento, el tratamiento de las temáticas y problemáticas específicamente ligadas al contexto español.

Published: January 2023

Dragon fruit (Hylocereus spp.) is a recently introduced super fruit in India, gaining popularity both in the rural and urban areas because of its attractive colour, delicious taste, high nutritive and medicinal values. It is adaptable to humid as well as semi-arid tropical and subtropical conditions. The growing acceptability of the fruit along with its immense antioxidants and medicinal properties has led to high demand of its cultivation followed quality planting materials in desired quantity. Dragon fruit can be propagated by various ways both sexually via seeds as well as asexually via stem cuttings, grafting and also via micropropagation. In this review various methods of propagation of dragon fruit are described along with some propagation aspects related to dragon fruit on which very limited information is available. Potential areas on dragon fruit propagation that require further research to generate more data in order to improve the techniques are also discussed.
Achieving Low‐Voltage Operation of Intrinsically‐Stretchable Organic Light‐Emitting Diodes

Published: January 2023

AbstractA minimum operating voltage of intrinsically‐stretchable organic light‐emitting diodes (ISOLEDs) is always required for practical applications. However, the lack of protocols for the lamination complicates the task of attaining a reliable ISOLED without inducing degradation. Here, a solvent‐vapor‐assisted lamination (SVAL) method to reinforce the cathode interface is presented; this process lowers the operation voltage and increases the stretchability of ISOLEDs. Achieving a uniform contact and strong adhesion at the interface is the key to attaining reliable lamination. A cold‐pressing (CP) treatment is applied first to reduce the surface roughness of silver nanowires before the surface embedding process. A subsequent solvent vapor treatment before the lamination partially solvated the surface of the active layer with an increase in the segmental motion of polymer chains, which substantially increases the interfacial adhesion after lamination. The combination of CP and SVAL treatments considerably reduces threshold voltage Vth (i.e., voltage at which current shows an abrupt increase for light‐emission) from 6.7 to 2.7 V. The ISOLED also exhibts excellent mechanical stretchability, with no significant change in luminance under 30% strain. This study can assist in the development of practical applications of intrinsically‐stretchable optoelectronic devices.

Published: January 2023

AbstractIron group metals chalcogenides, especially NiS, are promising candidates for K‐ion battery anodes due to their high theoretical specific capacity and abundant reserves. However, the practical application of NiS‐based anodes is hindered by slow electrochemical kinetics and unstable structure. Herein, a novel structure of Ni3S2–Ni hybrid nanosphere with intra‐core voids encapsulated by N‐doped carbon shells (Ni3S2‐Ni@NC‐AE) is constructed, based on the first electrodeposited NiS nanosphere particles, dopamine coating outer layer, oxygen‐free annealing treatment to form Ni3S2‐Ni core and N‐doped carbon shell, and selective etching of the Ni phase to form intra‐core void. The electron/K+ transport and K+ storage reaction kinetics are enhanced due to shortened diffusion pathways, increased active sites, generation of built‐in electric field, high K+ adsorption energies, and large electronic density of states at Fermi energy level, resulting from the multi‐structures synergistic effect of Ni3S2‐Ni@NC‐AE. Simultaneously, the volume expansion is alleviated due to the sufficient buffer space and strong chemical bonding provided by intra‐core void and yolk–shell structure. Consequently, the Ni3S2‐Ni@NC‐AE exhibits excellent specific capacity (438 mAh g−1 at 0.1 A g−1 up to 150 cycles), outstanding rate performances, and ultra‐stable long‐cycle performance (176.4 mAh g−1 at 1 A g−1 up to 5000 cycles) for K‐ion storage.

AbstractSequential deposition of the active layer in organic solar cells (OSCs) is favorable to circumvent the existing drawbacks associated with controlling the microstructure in bulk‐heterojunction (BHJ) device fabrication. However, how the processing solvents impact on the morphology during sequential deposition processes is still poorly understood. Herein, high‐efficiency OSCs are fabricated by a sequential blade coating (SBC) through optimization of the morphology evolution process induced by processing solvents. It is demonstrated that the device performance is highly dependent on the processing solvent of the upper layer. In situ morphology characterizations reveal that an obvious liquid–solid phase separation can be identified during the chlorobenzene processing of the D18 layer, corresponding to larger phase separation. During chloroform (CF) processing of the D18 layer, a proper aggregation rate of Y6 and favorable intermixing of lower and upper layers results in the enhanced crystallinity of the acceptor. This facilitates efficient exciton dissociation and charge transport with an inhibited charge recombination in the D18/CF‐based devices, contributing to a superior performance of 17.23%. These results highlight the importance of the processing solvent for the upper layer in the SBC strategy and suggest the great potential of achieving optimized morphology and high‐efficiency OSCs using the SBC strategy.

AbstractWe report data on survival and complications for a longitudinal cohort of 709 transfusion‐dependent β‐thalassemia major patients (51.1% males) born between 1970 and 1997 and followed through 2020 at seven major centers in Italy. Overall survival probability at 30 years was 83.6% (95%CI: 78.5–89.1) in the oldest birth cohort (1970–1974) compared with 93.3% (95%CI: 88.6–98.3) in the youngest birth cohort (1985–1997) (p = 0.073). Females showed better survival than males (p = 0.022). There were a total of 93 deaths at a median age of 23.2 years with the most frequent disease‐related causes being heart disease (n = 53), bone marrow transplant (BMT) complication (n = 10), infection (n = 8), liver disease (n = 4), cancer (n = 3), thromboembolism (n = 2) and severe anemia (n = 1). There was a steady decline in the number of deaths due to heart disease from the year 2000 onwards and no death from BMT was observed after the year 2010. A progressive decrease in the median age of BMT was observed in younger birth cohorts (p < 0.001). A total of 480 (67.7%) patients developed ≥1 complication. Patients in younger birth cohorts demonstrated better complication‐free survival (p < 0.001) which was comparable between sexes (p = 0.230). Independent risk factors for death in multivariate analysis included heart disease (HR: 4.63, 95%CI: 1.78–12.1, p = 0.002), serum ferritin >1000 ng/mL (HR: 15.5, 95%CI: 3.52–68.2, p < 0.001), male sex (HR: 2.75, 95%CI: 0.89–8.45, p = 0.078), and splenectomy (HR: 6.97, 95%CI: 0.90–54.0, p < 0.063). Survival in patients with β‐thalassemia major continues to improve with adequate access to care, best practice sharing, continued research, and collaboration between centers.

AbstractAll‐solid‐state batteries are promising candidates for safe energy‐storage systems due to non‐flammable solid electrolytes and the possibility to use metallic lithium as an anode. Thus, there is a challenge to design new solid electrolytes and to understand the principles of ion conduction on an atomic scale. We report on a new concept for compounds with high lithium ion mobility based on a rigid open‐framework boron structure. The host–guest structure Li6B18(Li3N) comprises large hexagonal pores filled with
Li7N] strands that represent a perfect cutout from the structure of α‐Li3N. Variable‐temperature 7Li NMR spectroscopy reveals a very high Li mobility in the template phase with a remarkably low activation energy below 19 kJ mol−1 and thus much lower than pristine Li3N. The formation of the solid solution of Li6B18(Li3N) and Li6B18(Li2O) over the complete compositional range allows the tuning of lithium defects in the template structure that is not possible for pristine Li3N and Li2O.

AbstractEnzymatischer Abbau und Recycling können die Umweltbelastung durch Plastik reduzieren. Trotz jahrzehntelanger Forschung wurde bisher nicht über Enzyme für die effiziente Hydrolyse von Polyurethanen berichtet. Während die Hydrolyse von Esterbindungen in Polyester‐Polyurethanen durch Cutinasen bekannt ist, blieben die Urethanbindungen in Polyether‐Polyurethanen für biokatalytische Hydrolyse bislang unzugänglich. Wir berichten hier über die Entdeckung von Urethanasen in einer Metagenombibliothek, erstellt aus einer Bodenprobe, welche Polyurethanabfall für viele Jahre ausgesetzt war. Wir demonstrieren weiterhin die Anwendung einer Urethanase in einem chemo‐enzymatischen Prozess zum Polyurethan‐Recycling. Diese Urethanase hydrolysiert niedermolekulare Dicarbamate, welche aus der chemischen Glykolyse von Polyether‐Polyurethanschaum entstehen, was diese Strategie breit anwendbar auf diverse Polyether‐Polyurethan Abfälle macht.

AbstractSide‐chain tailoring is a promising method to optimize the performance of organic solar cells (OSCs). However, asymmetric alkyl chain‐based small molecular acceptors (SMAs) are still difficult to afford. Herein, we adopted a novel asymmetricn‐nonyl/undecyl substitution strategy and synthesized two A‐D1A′D2‐A double asymmetric isomeric SMAs with asymmetric selenophene‐based central core for OSCs. Crystallographic analysis indicates thatAYT9Se11‐Clforms a more compact and order intermolecular packing compared toAYT11Se9‐Cl, which contributed to higher electron mobility in neatAYT9Se11‐Clfilm. Moreover, thePM6 : AYT9Se11‐Clblend film shows a better morphology with appropriate phase separation and distinct face‐on orientation thanPM6 : AYT11Se9‐Cl. The OSCs withPM6 : AYT9Se11‐Clobtain a superior PCE of 18.12 % compared toPM6 : AYT11Se9‐Cl(17.52 %), which is the best efficiency for the selenium‐incorporated SMAs in binary BHJ OSCs. Our findings elucidate that the promising double asymmetric strategy with isomeric alkyl chains precisely modulates the crystal packing and enhances the photovoltaic efficiency of selenophene‐incorporated SMAs.
Light Alters the NH3 vs N2H4 Product Profile in Iron‐catalyzed Nitrogen Reduction via Dual Reactivity from an Iron Hydrazido (Fe=NNH2) Intermediate

Published: January 2023

AbstractWhereas synthetically catalyzed nitrogen reduction (N2R) to produce ammonia is widely studied, catalysis to instead produce hydrazine (N2H4) has received less attention despite its considerable mechanistic interest. Herein, we disclose that irradiation of a tris(phosphine)borane (P3B) Fe catalyst, P3BFe+, significantly alters its product profile to increase N2H4 versus NH3; P3BFe+ is otherwise known to be highly selective for NH3. We posit a key terminal hydrazido intermediate, P3BFe=NNH2, as selectivity‐determining. Whereas its singlet ground state undergoes protonation to liberate NH3, a low‐lying triplet excited state leads to reactivity at Nα and formation of N2H4. Associated electrochemical and spectroscopic studies establish that N2H4 lies along a unique product pathway; NH3 is not produced from N2H4. Our findings are distinct from the canonical mechanism for hydrazine formation, which proceeds via a diazene (HN=NH) intermediate and showcase light as a tool to tailor selectivity.

AbstractElectrolyte freezing under low temperatures is a critical challenge for the development of aqueous batteries (ABs). While lowering the freezing point of the electrolyte has caught major research efforts, limited attention has been paid to the structural evolution during the electrolyte freezing process and regulating the frozen electrolyte structure for low temperature ABs. Here, we reveal the formation process of interconnected liquid regions for ion transport in frozen electrolytes with various in situ variable‐temperature technologies. More importantly, the low‐temperature performance of ABs was significantly improved with the colloidal electrolyte design using graphene oxide quantum dots (GOQDs), which effectively inhibits the growth of ice crystals and expands the interconnected liquid regions for facial ion transport. This work provides new insights and a promising strategy for the electrolyte design of low‐temperature ABs.

AbstractEnzymatic degradation and recycling can reduce the environmental impact of plastics. Despite decades of research, no enzymes for the efficient hydrolysis of polyurethanes have been reported. Whereas the hydrolysis of the ester bonds in polyester‐polyurethanes by cutinases is known, the urethane bonds in polyether‐polyurethanes have remained inaccessible to biocatalytic hydrolysis. Here we report the discovery of urethanases from a metagenome library constructed from soil that had been exposed to polyurethane waste for many years. We then demonstrate the use of a urethanase in a chemoenzymatic process for polyurethane foam recycling. The urethanase hydrolyses low molecular weight dicarbamates resulting from chemical glycolysis of polyether‐polyurethane foam, making this strategy broadly applicable to diverse polyether‐polyurethane wastes.

AbstractFacile evaluation of oxygen reduction reaction (ORR) kinetics for electrocatalysts is critical for sustainable fuel‐cell development and industrial H2O2 production. Despite great success in ORR studies using mainstream strategies, such as the membrane electrode assembly, rotation electrodes, and advanced surface‐sensitive spectroscopy, the time and spatial distribution of reactive oxygen species (ROS) intermediates in the diffusion layer remain unknown. Using time‐dependent electrochemiluminescence (Td‐ECL), we report an intermediate‐oriented method for ORR kinetics analysis. Owing to multiple ultrasensitive stoichiometric reactions between ROS and the ECL emitter, except for electron transfer numbers and rate constants, the potential‐dependent time and spatial distribution of ROS were successfully obtained for the first time. Such exclusively uncovered information would guide the development of electrocatalysts for fuel cells and H2O2 production with maximized activity and durability.

AbstractGraphene oxide (GO) can be self‐assembled with various polymer materials layer by layer to prepare composite materials with excellent barrier properties. However, the process is cumbersome and time‐consuming. In this article, GO/polyethyleneimine(PEI) hydrogen barrier films were successfully prepared by ultrasonic‐assisted layer‐by‐layer self‐assembly technology. Results show that the ultrasonic‐assisted method not only reduced the immersion time from several minutes to 10 s, but also increased the density of the material packing to reduce the channels through which hydrogen molecules can diffuse while improving the horizontal orientation of the GO sheet to prolong the diffusion paths of gas molecules. Finally, the hydrogen transmission rate of 20‐bilayer films assembled under ultrasonic conditions is equivalent to that of 30‐bilayer films assembled without ultrasonic conditions, which greatly shortens the film‐making period. Therefore, the ultrasonic‐assisted method has a good prospect in the preparation of gas barrier films.

AbstractStreptococcus mutansis a main organism of tooth infections including tooth decay and periodontitis. The aim of this study was to assess the influence of sucrose and starch on biofilm formation and proteome profile ofS. mutansATCC 35668 strain. The biofilm formation was assessed by microtiter plating method. Changes in bacterial proteins after exposure to sucrose and starch carbohydrates were analyzed using matrix‐assisted laser desorption/ionization mass spectrometry. The biofilm formation ofS. mutanswas increased to 391.76% in 1% sucrose concentration, 165.76% in 1% starch, and 264.27% in the 0.5% sucrose plus 0.5% starch in comparison to biofilm formation in the media without sugars. The abundance of glutamines, adenylate kinase, and 50S ribosomal protein L29 was increased under exposure to sucrose. Upregulation of lactate utilization protein C, 5‐hydroxybenzimidazole synthase BzaA, and 50S ribosomal protein L16 was formed under starch exposure. Ribosome‐recycling factor, peptide chain release factor 1, and peptide methionine sulfoxide reductase MsrB were upregulated under exposure to sucrose in combination with starch. The results demonstrated that the carbohydrates increase microbial pathogenicity. In addition, sucrose and starch carbohydrates can induce biofilm formation ofS. mutansvia various mechanisms such as changes in the expression of special proteins.
