AbstractIn their Correspondence, Sergey V. Krivovichev and Luca Bindi argue that the novel excellent nonlinear optical material antimony pyrophosphate, K2Sb(P2O7)F, reported in our Research Article published in this journal belongs to the fresnoite Ba2[TiO(Si2O7)] group and its structure is not novel in terms of either topology or local coordination geometry around Sb3+ cations. We clarify that the statements regarding structural features of our original paper are valid in context.
Effects of four isocyanates and four plasticizers on the thermomechanical and tensile properties of hydroxyl‐terminated polybutadiene elastomers and the effect of solid particle filling
Authors: Seyidoglu Tijen , Bohn Manfred A. 
Published: December 2020

AbstractThe aim of this study is to analyze effect of four different isocyanates and four different plasticizers in hydroxyl‐terminated polybutadiene (HTPB) based elastomers by quantitative analysis of the shape of the loss factor (tan δ), tensile strength, deformation frequency shift of the maximum temperatures of loss moduli G" and of tan δ. The first part of the study shows intensities of the tan δcurves with the four isocyanates follow the order HDI > IPDI > H12MDI > Desmodur™ E305. By molecular modeling of the isocyanates and the corresponding polyurethane parts the influence of molecular geometry on tan δare discussed. The second part of the study analyzes HTPB‐IPDI elastomers with the four different plasticizers DOA, DOS, DOZ, and IDP. The IDP provides lowestTgat about −83°C, while the others provide at about −78°C. In the third part, aluminum (Al‐18 μm) and ammonium perchlorate (AP‐200 μm) are added to HTPB‐IPDI+DOA to analyze the effect of particle size, wt% content and particle type on the shape and intensity of the tan δcurves. From the frequency shift of the two maximum temperatures one receives activation energies Eaf. Their average values without and with plasticizer are with tan δ178 and 165 kJ/mol and with G" 274 and 248 kJ/mol, respectively.
Thermal conductivity enhancement of liquid crystalline epoxy/MgO composites by formation of highly ordered network structure
Authors: Ota Saki , Harada Miyuki 
Published: December 2020

AbstractTo develop a high thermal conductive composite, an MgO filler was incorporated into a liquid crystalline (LC) epoxy containing a mesogenic moiety. The thermal conductivity of the obtained composite was 1.41 W/(m∙K) at 33 vol% content, which was remarkably higher than the value predicted using Bruggeman's model. To investigate the reason for this significant enhancement of the thermal conductivity in the LC epoxy composites, the LC phase structure of the composite was analyzed by a polarized optical microscope, an X‐ray diffractometry (XRD) and a polarized IR mapping measurement. An XRD analysis indicated the local formation of a highly ordered smectic phase structure, even in the high‐loading composite. This result indicated the promotion of the self‐assembly of the mesogenic network polymer chains by the MgO filler loading. We considered that this highly ordered structural formation can lead to an increase in the matrix resin's thermal conductivity, which can result in the effective enhancement of the thermal conductivity in the LC epoxy/MgO composite.
The vascular origins of antero‐medial tibial bowing in congenital fibular deficiency
Authors: Horton Jason A. , Hootnick David R. 
Published: December 2020

AbstractAnteromedial bowing and shortening of the tibia are intrinsic features of limbs with congenital fibular deficiency (CFD). Tibial bowing occurs more frequently when the fibula is radiographically absent rather than deficient. The bowing has been attributed to rapid longitudinal growth of the tibial anlage coupled with anteromedial tibial bending moments of the posterior crural and lateral peroneal musculature unopposed in the absence of a fibular strut. Eccentric mechanical loading results in asymmetric mineral deposition and thickening of the diaphyseal cortex. Skeletogenesis depends upon an intimate interplay between the normally prefigured tibial cartilage anlage and beginning muscular contractile actions during initial vascularization of the anlage, while the embryonic limb vasculature is undergoing a series of transitions. A diaphyseal periosteal collar normally forms at the site of nutrient artery invasion and stabilizes the growing anlage. In CFD however, arteriography consistently reveals anomalous tibial nutrient arterial branches, which originate from a primitive axial artery rather than from the usual posterior tibial artery. These anomalous nutrient arteries enter the tibial shaft at the posterior aspect of the proximal metaphysis, establishing an eccentric bone collar. The developing vasculature of the embryonic limb is responsive to the then most metabolically active tissues. Disruption of the reciprocal relationship between the transitioning vasculature and the developing long bones is pivotal in producing the diverse skeletal malformations of the congenital short limb (CSL). Embryonic vascular dysgenesis contributes not only to the well‐recognized congenital tibial and fibular shortenings but also predisposes to congenital anteromedial bowing of the tibia.
Synthesis and Processing of Battery Materials: Giving it the Plasma Touch
Authors: Rangasamy Vijay Shankar , Vanhulsel Annick 
Published: December 2020

AbstractLi‐ion batteries (LIBs) are currently the most preferred energy storage devices in portable applications. Recent surge in the production of electric vehicles in the wake of the current global warming scenario has strongly increased the demand for LIBs, thereby reinforcing the need for new battery chemistries as well as making the existing production chain more efficient and sustainable. Several new technologies are explored to achieve these goals. Among them, plasma technology has the potential to simplify the synthesis and modification of battery materials, enable ‘dry’ and ‘green’ processing that eliminate the need for solvents that are often toxic, expensive, flammable, and energy‐intensive. In this review, we have attempted to provide an overview of state‐of‐the‐art (scientific) research and development with respect to the application of plasma‐based processes in the synthesis and modification of materials for battery components. We have explored various applications wherein plasma‐based processes have been demonstrated in the processing of electrode materials, electrolytes, and separators in addition to the recent developments in the context of solid‐state and flexible batteries. Our analysis shows that plasma‐based technologies are slowly but steadily gaining attention in these areas. Several technical and conventional issues remain, which require innovations at the conceptual as well as engineering levels. Technical issues include the selection of appropriate plasma type and precursors, plasma density, selectivity, and a preferable shift from vacuum to atmospheric conditions. The conventional issues include the practical difficulties in converting or adapting the assembly lines to plasma‐based technology. From a business perspective, all that matters is the cost per mAh g−1 of energy produced, for which, unfortunately, we do not have sufficient quantitative data yet with regard to the materials processed by plasma‐based technologies. However, the battery manufacturing sector is now open for innovations like never before. Therefore, it remains to be seen how plasma technologies embrace this opportunity and penetrate the battery production sector, where the key parameters are efficiency and cost‐effectiveness. Would ‘giving it the plasma touch’ bring added value to the battery manufacturing processes? That is the question we try to address in this review.

Published: December 2020

AbstractDurch die Einbeziehung von gemessenen Daten bei der Bewertung von bestehenden Bauwerken können Unsicherheiten bei der Beurteilung des Tragverhaltens reduziert werden, ohne das normative Zuverlässigkeitsniveau einzuschränken. Informationen sind die wesentliche Grundlage für die Analyse der Zuverlässigkeit von Tragwerken. Umso wichtiger ist die Kenntnis über die Präzision und die Richtigkeit der verwendeten Informationen. Aus messtechnischer Sicht kann ein Messwert, dem keine Messunsicherheit beigeordnet wurde, als wertlos erachtet werden. Liegt ein vollständig dokumentiertes Messergebnis vor, so ist die Qualität der gemessenen Information bekannt und deren Vergleichbarkeit gewährleistet. In diesem Beitrag wird am Beispiel einer Spannbetonbrücke und zweier Grenzzustände gezeigt, wie Messergebnisse aus der zerstörungsfreien Prüfung in probabilistische Nachweise von Bestandsbauwerken einfließen können und welche Auswirkungen die Implementierung von gemessenen Daten bei der Bewertung von Bestandsbauwerken haben kann.
Untersuchungen zum Tragverhalten von Verbunddübelleisten in schlanken Stegen aus ultrahochfestem Beton
Authors: Lechner Thomas , Fischer Oliver 
Published: December 2020

AbstractUltrahochfester Beton (UHFB) kommt mittlerweile immer häufiger im Bauwesen zum Einsatz. Durch die aktuelle Entwicklung von nationalen und internationalen Richtlinien und Normen ist zu erwarten, dass sich dieser Trend fortsetzt und vermehrt Konstruktionen aus diesem modernen Baustoff realisiert werden. Dies gilt auch für den Bereich des Verbundbaus. Eine interessante Anwendungsmöglichkeit stellen hierbei Verbundträger mit externer Bewehrung dar, bei denen der Stahlflansch als reines Zugtragglied außerhalb des Betons liegt. Die schubfeste Verbindung zwischen der externen Bewehrung und dem möglichst dünnen Steg aus ultrahochfestem Beton erfolgt dann zielführend über Verbunddübelleisten, die dabei nur eine sehr geringe seitliche Betondeckung besitzen. Daher kommt der Ermittlung der Schubtragfähigkeit von Verbunddübelleisten in diesem Fall besondere Bedeutung zu. Im Rahmen des Beitrags werden die Ergebnisse der experimentellen und numerischen Untersuchungen an Push‐out‐Körpern beschrieben, die dazu dienten, die Trag‐ und Verformungsfähigkeit von Verbunddübelleisten in schlanken Stegen aus UHFB zu untersuchen. In einem Folgebeitrag werden Vorschläge für wirklichkeitsnahe Bemessungsmodelle vorgestellt und diskutiert sowie der Versuchsaufbau und die Ergebnisse von Versuchen am Gesamtsystem (Verbundträger mit externer Bewehrung) erläutert.

AbstractKidney transplantation is the most promising treatment to improve mortality and life quality in end‐stage kidney disease; however, cancer remains a leading cause of death. Several factors including immunosuppressants might be associated with a gradual increase in cumulative cancer incidence after kidney transplantation. Risk factors for cancer and overall and cancer‐specific survival were analyzed in 1973 kidney transplant recipients from three study institutions in Japan. The 5‐, 10‐, 20‐, and 30‐year overall and cancer‐specific survival rates were 93.3%, 88.4%, 78.0%, and 63.6% and 99.4%, 98.0%, 95.3%, and 91.7%, respectively. The overall survival rate was significantly higher and the graft survival rate was significantly lower in recipients without cancer than in those with cancer. Older recipient age, longer dialysis duration before kidney transplantation, and history of transfusion were significant predictors of cancer. Dialysis duration before kidney transplantation was a prognostic factor of overall survival rate. Regarding cancer‐specific survival rates, older recipient age and dialysis duration before kidney transplantation were prognostic factors of worse cancer‐specific survival rates. The type of immunosuppressant was not associated with an increased cancer rate. Aggressiveness of immunosuppressant regimens or potent immunosuppressants might improve graft survival rate while inducing de novo cancer after kidney transplantation. Older age and longer dialysis duration before kidney transplantation were risk factors of cancer‐specific survival rate.
Aversion amplification in the emerging COVID‐19 pandemic: The impact of political trust and subjective uncertainty on perceived threat
Authors: Lalot Fanny , Abrams Dominic , Travaglino Giovanni A. 
Published: December 2020

AbstractHealth psychology shows that responses to risk and threat depend on perceptions as much as objective factors. The present study focuses on the precursors of perceived threat of COVID‐19. We draw on political and social psychology and use the aversion amplification hypothesis to propose that subjective uncertainty and political trust should interactively impact perceived threat. We conducted a cross‐sectional survey amongst the general population of Scotland (N = 188) in the early period of the COVID‐19 pandemic in the UK. We hypothesised that high political trust should ameliorate the threat‐elevating impact of uncertainty, thereby reducing the perceived threat from a high to moderate level. This hypothesis was supported, even after accounting for demographic differences. The discussion addresses the implications of the interactive role of trust and uncertainty for strategies to manage public behaviour as the pandemic progresses.

Published: December 2020

AbstractMicrobial bile salt hydrolases (BSHs) found in the intestine catalyze the deconjugation of taurine‐ and glycine‐linked bile salts produced in the liver. The resulting bile salts are biological detergents and are critical in aiding lipophilic nutrient digestion. Therefore, the activity of BSHs in the gut microbiome is directly linked to human metabolism and overall health. Bile salt metabolism has also been associated with disease phenotypes such as liver and colorectal cancer. In order to reshape the gut microbiome to optimize bile salt metabolism, tools to characterize and quantify these processes must exist to enable a much‐improved understanding of how metabolism goes awry in the face of disease, and how it can be improved through an altered lifestyle and environment. Furthermore, it is necessary to attribute metabolic activity to specific members and BSHs within the microbiome. To this end, we have developed activity‐based probes with two different reactive groups to target bile salt hydrolases. These probes bind similarly to the authentic bile salt substrates, and we demonstrate enzyme labeling of active bile salt hydrolases by using purified protein, cell lysates, and in human stool.

AbstractLaryngeal squamous cell carcinoma (LSCC) is the most common malignant tumor, which occurs in the head and neck. Current treatments for LSCC are all largely weakened by increasing drug resistance. Our study aimed to investigate the effects of long noncoding RNA (lncRNA) H19 on drug resistance in LSCC. In our study, we found that the level of H19 was sharply upregulated in LSCC tissues and drug‐resistant cells compared with the control. Besides, the expression of high‐mobility group B1 (HMGB1) was elevated, and microRNA107 (miR‐107) was suppressed in drug‐resistant cells compared with the control. Further study revealed that the interference of H19 by short hairpin RNA (shRNA) effectively suppressed high autophagy level and obvious drug resistance in drug‐resistant cells. Besides that, miR‐107 was predicted as a target of H19 and inhibiting effects of H19 shRNA on autophagy and drug resistance were both reversed by miR‐107 inhibitor. Moreover, HMGB1 was predicted as a target of miR‐107 in LSCC cells and knockdown of HMGB1 was able to suppress autophagy and drug resistance in LSCC cells. In addition, our investigation demonstrated that H19 shRNA exerted an inhibiting effect on autophagy and drug resistance by downregulating HMGB1 by targeting miR‐107. Finally, the in vivo experiment revealed that LV‐H19 shRNA strongly suppressed drug resistance compared with the usage of cisplatin individually. Taken together, our research indicated an H19–miR‐107–HMGB1 axis in regulating the autophagy‐induced drug resistance in LSCC in vitro and in vivo, providing novel targets for molecular‐targeted therapy and broadening the research for LSCC.

AbstractBackgroundTranscatheter aortic valve replacement (TAVR) via transaxillary (TAx) approach with ACURATE neo valve is an off‐label procedure. Our aim was to gather information on ACURATE neo cases implanted via TAx approach and report major outcomes.Methods and ResultsThe TRANSAX Study (NCT04274751) retrospectively gathered patients from nine centres in Europe and North America treated with ACURATE neo valve through TAx approach up to May/2019. Follow up was pre‐specified at 1‐year and was obtained for all patients.A total of 75 patients (79 ± 10 years; 32% women) were included. Left axillary (72%) and conscious sedation (95.2%) were the most common setting. Risk scores were higher when right axillary artery and surgical cut‐down were selected. Severe complications including valve embolization, coronary obstruction, annulus rupture, and procedural mortality did not occur. Cardiac tamponade occurred in two cases (2.7%) with one requiring conversion to open surgery (1.3%). Bail‐out stenting and surgical vascular repair were required in 7 (9.3%) and 3 (4%) cases, respectively. The need for new permanent pacemaker was 8%. Procedural success (96%), in‐hospital (2.7%), and 1‐year mortality (8%) were comparable in all settings. Only one case (1.3%) complicated with cerebrovascular event and one (1.3%) presented moderate aortic regurgitation before discharge.ConclusionsTAx TAVR procedures with the ACURATE neo valve were presented high success rate and low in‐hospital and 1‐year mortality.

Published: December 2020

AbstractThe use of inexpensive graphite oxide (GO) as a carbon source, instead of the expensive reduced graphene oxide (rGO), is essential to prepare metal oxide/rGO composites. In this work, we investigated the in situ reaction of GO and FeCl3 to produce Fe2O3/rGO composites as anode materials for high‐energy lithium‐ion batteries (LIBs). In this reaction, iron ions combined with the oxygen‐containing functional groups of GO, which subsequently grew into Fe2O3 nanoparticles, whereas the GO transformed into rGO under hydrothermal conditions. In the composite Fe2O3−rGOx samples, intergranular gaps in the Fe2O3 sub‐micron particles evidently increased the contact between the Fe2O3 active material and the electrolyte, which improved the Li‐ion conductivity and electrochemical performance of the Fe2O3−rGOx composites. The Fe2O3−rGO2 sample showed the best cyclic performance and delivered the highest capacity of all samples. The initial discharge and charge capacities of Fe2O3−rGO2 were 1086.3 and 722.4 mAh g−1, respectively. After 100 cycles, the discharge specific capacity of Fe2O3−rGO2 was 653.2 mAh g−1 and the coulombic efficiency was 98.4 %. We found that an appropriate weight ratio and composite morphology of Fe2O3−rGOx were important in influencing the electrochemical properties of the composite anode materials for high‐energy LIBs.

Published: December 2020

AbstractSelective modification of the morphology and intrinsic electrocatalytic activity of porous electrodes is urgently required to improve the performance of vanadium redox flow batteries (VRFBs). For this purpose, electrospinning was exploited to prepare high‐performance nanofiber‐based composites. Blends of polyacrylonitrile, polyacrylic acid, and polyaniline with carbon black were electrospun into a 3D free‐standing nanofibrous web, which was utilized as a novel electrode. By extending the recent theory of cyclic voltammetry at porous electrodes to account for interfacial double‐layer capacities, nonlinear effects of ohmic resistances, and parasitic reactions, we could quantitatively investigate non‐faradaic as well as desired and undesired faradaic current contributions. Combination of experimental and theoretical studies allowed a unique quantitative assessment of the intrinsic catalytic activity of selected electrode materials concerning the VO2+/VO2+ redox reaction.

Published: December 2020

AbstractThe introduction of unconventional elements into π‐conjugated systems has been studied to manipulate the electronic states and properties of compounds. Herein, boron‐ and germanium‐containing hybrid macrocycles, as a new class of element‐hybrid conjugated systems, have been synthesized. The palladium‐catalyzed Stille cross coupling of bis(bromothienyl)borane and bis(trimethylstannylthienyl)‐ or bis(trimethylstannylphenyl)‐substituted dithienogermoles as the boron‐ and germanium‐containing building blocks, respectively, produced a mixture of several macrocyclic compounds. Single‐crystal X‐ray analysis of the 2:2 coupling product revealed a planar structure with a cavity inside the macrocycle. The optical properties of the macrocyclic products indicated rather small electronic interactions between the building units. However, intramolecular photoenergy transfer from the dithienogermole unit to the boron unit was clearly observed with respect to the fluorescence spectra.
