Authors: Tian Jinjun , Xue Yan , Wu Keliang , Guo Meng , Zeng Xiancai 
Published: December 2021

AbstractHexagonal nanoplates of Ni(OH)2 were provided using Tetrapropylammonium hydroxide (TPAOH) as a surfactant and an alkali wherein the particle dimensions and morphological attributes were controlled by TPAOH. The nanoplates of Ni(OH)2 were hexagonal with an average diameter of 62 nm and a 4.4 nm thickness. At a current density of about 0.5 A g−1, the hexagonal nanoplates of Ni(OH)2 were detected to exhibit a beneficial specific capacitive performance of 1462 F g−1. The Ni(OH)2 nanoplate//activate carbon (AC) asymmetrical supercapacitor (ASC) presented excellent energy density 30.0 W h kg−1 at a power density of 250 W kg−1. ASC manifested tremendous cycling stability, preserving 72.73 % of its primary capacitance following 7500 cycles.

Published: December 2021

AbstractA new series of organic‐inorganic‐hybrid‐systems (OIHS) was synthesized with the aim of developing metallogels that might display ‘drug‐like’ function. Reaction of two dicarboxylate ligands namely 3‐carboxycinnamic acid (3‐cca) and 4‐carboxycinnamic acid (4‐cca) with various bivalent metal ions (Cu(II), Zn(II), Co(II), Cd(II), Mn(II)) produced a new series of OIHS which were crystallographically characterized; five of which were coordination polymers (CP1‐CP5) and one metal‐organic polyhedra (MOP‐1). Reaction of 3‐cca with various metal ions in presence of DMSO/water produced five metallogels (MG1‐MG5) of which the Zn(II)‐metallogel namely MG1 was evaluated for both anti‐cancer and anti‐bacterial properties against murine tumor cell line B16‐F10 (human skin cancer model) and gram positive bacterium S. aureus. While MTT and cell migration assays established the anti‐cancer activity of MG1 against B16‐F10, flow cytometry and laser scanning confocal microscopy (LSCM) images under various staining conditions supported apoptotic pathway of cancer cell death. Anti‐bacterial ability of MG1 was also established against S. aureus by zone inhibition, and flow cytometry and LSCM studies under various staining conditions. MG1 was also demonstrated to be effective in killing the intracellular bacterial cells when B16‐F10 cells were infected with S. aureus thereby suggesting its potential in treating post‐operative cancer surgery model system.

Published: December 2021

AbstractA heterogeneous and hard bound TiIV anchored MCM‐41 material has been successfully evaluated for catalytic applications in the one pot synthesis of highly functionalized β‐amino ketones and quinoline appended π‐conjugated imines via Mannich reaction and condensation reaction, respectively. The synthetic transformation was successfully catalyzed via the dual Bronsted and Lewis acetic nature of the Ti‐MCM‐41 material that provided excellent yields of the desired products. The heterogeneous catalyst shows good catalytic performance, facile separation from the reaction mixture and can be reused in more than five catalytic cycles without any significant loss in the yield.

AbstractIn the present study, the effect of moisture and thermal aging on the degradation of a pyrotechnic igniter composition (PIC) composed of magnesium (Mg) as fuel and dual‐oxidizer of barium nitrate (Ba(NO3)2) and barium peroxide (BaO2) has been investigated to well understand the main compositional and structural changes that may occur. The unaged and aged samples were examined through non‐destructive techniques, namely, Raman and Fourier transform infrared (FTIR) spectroscopies, scanning electron microscopy (SEM), and X‐ray diffraction (XRD). The thermal decomposition behavior and the kinetic parameters of the different Mg‐PIC samples were determined using thermogravimetry (TGA) analysis coupled with a deconvolution approach. The obtained results revealed that the aging processes performed at 65 °C and 85 % relative humidity (RH), respectively, affected the chemical structure of the samples, and the degradation became more pronounced with the increase of the aging time. These changes are attributed to the partial decomposition of barium nitrate, barium peroxide, and the oxidation of magnesium, which generated Ba(NO2)2, MgO, and Mg(OH)2 as degradation products. On the other hand, based on the TGA data, the kinetic modelling was carried out through the deconvolution approach combined with isoconversional kinetic analysis to determine the multiple‐step kinetic behaviors of the different PIC samples. The results revealed that the aging processes may engender various degradation reactions with different activation energies compared to the fresh sample, what can lead to severe changes in stability and untrustworthy performance of the pyrotechnic compositions.

AbstractAn efficient enantioselective synthesis of a set of (R)‐phenylalkylesters and their analogues amides via enzymatic acylation of 1‐phenylethanol (rac‐1) and 1‐phenylethanamine (rac‐2) using carboxylic acids with different chain‐lengths as green acyl donor is reported. Three lipases are used: Candida antarctica B immobilized on acrylic resin (CAL‐B) and two free lipases: Pseudomonas cepacia (PCL) and Candida rugosa (CRL). The CAL‐B shows an excellent selectivity during the acylation of rac‐1 without restriction due to the acyl carbon chain‐length, the (R)‐ esters (1 a–1 f) were obtained enantiopures (ee up to 99 %). For the first time, the PCL catalyzed O‐acylation allows smoothly to (R)‐(1 d–1 f) with high selectivity (E⋙200) is described. The conversions increase with the length of the carbon‐chain of the acyl donor (28.7 %≤C≤40 %). The CRL shows less selective and provided the (R) (1 b–1 e) with 77 %≤eep≤86.4 %. Due to its high thermostability, the CAL‐B is used for the N‐acylation of rac‐2 and provides access to enantioenriched (R)‐fatty amides (2 d–2 f) (60.7 %≤eep≤74.4 %) and the remained (S)‐2 with ees>91 %.

Published: December 2021

AbstractLow band gap photocatalysts are desirable for efficient performance. We report synthesis of cobalt‐doped TiO2 photocatalysts, inside radial pores of nano‐spherical silica (RPNS) particles, having different weight percentages of dopant (0.1 to 4 wt.% Co‐TiO2‐RPNS). Doping decreases both optical band gap and electron‐hole charge separation, with maximum decrease in charge transfer resistance, for 1 wt.% Co‐TiO2‐RPNS (0.74 kΩ.cm−2), compared to TiO2‐RPNS (1.18 kΩ.cm−2). However, it shows only partial degradation of rhodamine B dye. Hence, the 1 wt.% Co‐TiO2‐RPNS catalyst was further investigated with respect to different e−/h+ recombination processes, in presence of any one of the scavengers ‐ e− (K2S2O8) or OH* (butanol) or h+ (EDTA). An e− scavenger shows a higher dye degradation (rate constant 1.24 h−1), while h+ scavenger shows a lower rate (0.38 h−1), in contrast to no scavenger (0.91 h−1). Oxygen purging as a reaction promoter inhibited e−/h+ recombination, doubling overall rate (4.66 h−1). So, scavenger and oxygen purging together can further enhance a low band gap photocatalyst's activity.

Published: December 2021

AbstractCobalt‐catalyzed carbonylative ring expansion of thietane under ambient CO pressure was developed, affording a variety of thioacetones in moderate to high yields. dual roles of Co2(CO)8 as the precursor of both carbonylation catalyst and Lewis acid was revealed by control experiments and spectroscopic characterization. The carbonylative ring expansion under CO gas‐free conditions was demonstrated by using Co2(CO)8 as both CO surrogate and pre‐catalyst.

Published: December 2021

AbstractMethods to synthesize α‐substituted alkenyl sulfoxides are highly useful as they are widely used to construct diverse molecules of high synthetic importance. We have described a synthetic route for expedient access to the numerous α‐substituted alkenyl sulfoxides from alkynes and β‐sulfinyl esters. This protocol exhibits a vast substrate scope, readily accommodates a wide range of functional groups, and is scalable in a gram‐scale. Besides, we demonstrated a direct synthesis of alkenyl sulfoxides from thiols via the in situ generation of the requisite β‐sulfinyl ester. The ensuing α‐substituted alkenyl sulfoxide product was readily transformed into benzofuran and sulfonyl derivatives. Mechanistic investigations were done to comprehend the reaction mechanism.
Monitoring der Theodor‐Heuss‐Brücke – Teil 1 – Veranlassung, Monitoringkonzept und Erkenntnisse zum Tragverhalten

Published: December 2021

AbstractDie Theodor‐Heuss‐Brücke in Düsseldorf ist die älteste Schrägseilbrücke Deutschlands und die weltweit erste mit harfenförmig angeordneten Seilen. Seit ihrer Fertigstellung 1957 ist die Verkehrsbelastung stetig gestiegen. Wie bei vielen anderen älteren Brücken mit orthotropen Fahrbahnplatten führte dies mit der Zeit zu Schäden – u. a. in Form von Rissen. Eine Nachrechnung des Bauwerks zeigt deutliche Defizite – insbesondere hinsichtlich der Ermüdung in der orthotropen Fahrbahnplatte. Daher wurde 2019 ein Monitoringsystem aus über 80 Sensoren am Bauwerk installiert und über ein Jahr betrieben. Der Beitrag zeigt die Entwicklung des Monitoringkonzepts, seine Umsetzung und Auswertung. Aus den Messdaten werden Erkenntnisse zum Tragverhalten abgeleitet. So zeigt sich ein signifikanter Zusammenhang zwischen den ermüdungswirksamen Beanspruchungen und der Temperatur. Einerseits wirkt die steife Asphaltschicht beim Lastabtrag mit, andererseits bewirkt sie eine größere Lastverteilung. Auch zeigt das Monitoring, dass der Einfluss von Radlasten dominiert und eine Ablastung über das zulässige Fahrzeuggesamtgewicht nur geringen Nutzen hat. Vielmehr sind die Radlasten zu begrenzen, um die Bauteile der Fahrbahnplatte zu entlasten.

AbstractBackgroundEducating patients regarding thier inflammatory bowel disease (IBD) is important for their empowerment and disease management. We aimed to develop a questionnaire to evaluate patient understanding and knowledge of IBD.MethodsWe have developed the Understanding IBD Questionnaires (U‐IBDQ), consisting of multiple‐choice questions in two versions [for Crohn's disease (CD) and ulcerative colitis (UC)]. The questionnaires were tested for content and face validity, readability, responsiveness and reliability. Convergent validity was assessed by correlating the U‐IBDQ score with physician's subjective assessment scores. Discriminant validity was assessed by comparison to healthy controls (HC), patients with chronic gastrointestinal (GI) conditions other than IBD, and to GI nurses. Multivariate analysis was performed to determine factors associated with a high level of disease understanding.ResultsThe study population consisted of IBD patients (n = 106), HC (n = 35), chronic GI disease patients (n = 38) and GI nurses (n = 19). Mean U‐IBDQ score among IBD patients was 56.5 ± 21.9, similar for CD and UC patients (P = 0.941), but significantly higher than that of HC and chronic GI disease patients and lower than that of GI nurses (P < 0.001), supporting its discriminant validity. The U‐IBDQ score correlated with physician's subjective score (r = 0.747, P < 0.001) and was found to be reliable (intra‐class correlation coefficient = 0.867 P < 0.001). Independent factors associated with high U‐IBDQ scores included academic education (OR = 1.21, 95% CI 1.10–1.33, P < 0.001), biologic therapy experience (OR = 1.24, 95% CI 1.01–1.53, P = 0.046), and IBD diagnosis at <21 years of age (OR = 2.97, 95% CI 1.05–8.87, P = 0.050).ConclusionsThe U‐IBDQ is a validated, reliable and short, self‐reported questionnaire that can be used for assessing understanding of disease pathophysiology and treatment by IBD patients.
Marked, persistent basophilia in a potbellied pig

Published: December 2021

AbstractA 5‐year‐old intact female potbellied pig presented for a 2‐week history of anorexia, lethargy, and intermittent fever. Over 2 months, serial complete blood count evaluations revealed a persistent, progressive, marked basophilia and differential diagnoses included parasitism, hypersensitivity reaction, paraneoplastic response, or basophilic leukaemia. The patient was diagnosed with basophilic leukaemia based on the persistent, marked basophilia and exclusion of other differentials. Due to possible inconsistencies in basophil identification by automated haematology analysers, blood smear examination must be performed to quantify circulating basophils. Diagnosis of basophilic leukaemia is based on light microscopic examination of blood and/or bone marrow and exclusion of other differentials. While basophilic leukaemia is rare in veterinary medicine, it should be considered a differential for a marked, persistent basophilia in any species. This case highlights some of the challenges associated with diagnosing and treating this disorder.
Comments on wormholes, ensembles, and cosmology
Authors: Van Raamsdonk Mark 
Published: December 2021

Abstract
Certain closed-universe big-bang/big-crunch cosmological spacetimes may be obtained by analytic continuation from asymptotically AdS Euclidean wormholes, as emphasized by Maldacena and Maoz. We investigate how these Euclidean wormhole spacetimes and their associated cosmological physics might be described within the context of AdS/CFT. We point out that a holographic model for cosmology proposed recently in arXiv:1810.10601 can be understood as a specific example of this picture. Based on this example, we suggest key features that should be present in more general examples of this approach to cosmology. The basic picture is that we start with two non-interacting copies of a Euclidean holographic CFT associated with the asymptotic regions of the Euclidean wormhole and couple these to auxiliary degrees of freedom such that the original theories interact strongly in the IR but softly in the UV. The partition function for the full theory with the auxiliary degrees of freedom can be viewed as a product of partition functions for the original theories averaged over an ensemble of possible sources. The Lorentzian cosmological spacetime is encoded in a wavefunction of the universe that lives in the Hilbert space of the auxiliary degrees of freedom.
The colour matrix at next-to-leading-colour accuracy for tree-level multi-parton processes
Authors: Frederix Rikkert , Vitos Timea 
Published: December 2021

Abstract
We investigate the next-to-leading-colour (NLC) contributions to the colour matrix in the fundamental and the colour-flow decompositions for tree-level processes with all gluons, one quark pair and two quark pairs. By analytical examination of the colour factors, we find the non-zero elements in the colour matrix at NLC. At this colour order, together with the symmetry of the phase-space, it is reduced from factorial to polynomial the scaling of the contributing dual amplitudes as the number of partons participating in the scattering process is increased. This opens a path to an accurate tree-level matrix element generator of which all factorial complexity is removed, without resulting to Monte Carlo sampling over colour.
Decomposition of d = 9 short-range 0νββ decay operators at one-loop level
Authors: Chen Ping-Tao , Ding Gui-Jun , Yao Chang-Yuan 
Published: December 2021

Abstract
We perform a systematical study of the dimension-9 short-range 0νββ decay operators at one-loop level. There are only six genuine topologies which generate eight diagrams, and the recipe to identify the possible one-loop realizations of the 0νββ decay operators is sketched. Certain hypercharge assignments are excluded by the absence of tree-level diagrams in a genuine one-loop model. The mediators of each decomposition can generate Majorana neutrino masses which are discussed up to two-loop level. We present an example of 0νββ decay model in which the neutrino masses are generated at two-loop level, and the short-range contribution can be comparable with the mass mechanism in some region of parameter space.

Abstract
Purpose
The prevalence of long-term olfactory and gustatory dysfunction in participants suffering from sudden chemosensory loss due to coronavirus disease 2019 (COVID-19) is unknown. Furthermore, evaluations of the reliability of participants’ self-reporting of olfactory function (SOF) and gustatory function (SGF) using extended objective psychophysical testing are missing.

Methods
In this population-based cohort study in a PCR-tested community in Thuringia, Germany, olfactory function was extensively examined 4 months after a COVID-19 outbreak using the “Sniffin Sticks” test battery to determine the TDIa score, i.e., the sum of results obtained for threshold, discrimination, and identification scores averaged for both nasal sides. Gustatory function was assessed using the three-drop test resulting in the gustatory composite score (CSg). The data were compared with SOF and SGF.

Results
Of 43 adult convalescents (median age: 68 years; 58% female) after SARS-CoV‑2 infection, 18 participants (42%) had olfactory complaints due to SOF, one participant (2%) complained of taste disturbance due to SGF. The TDIa was 22.0 ± 5.9. Normosmia, hyposmia, and anosmia were seen in 17, 18, and eight participants, respectively. TDIa correlated with SOF (rs = −0.434, p = 0.004); CSg was 23.5 ± 2.7. Normogeusia and hypogeusia were objectified in 39 and four participants, respectively. The prevalence of long-term olfactory dysfunction and gustatory dysfunction in the study group was 60.5 and 9.3%, respectively.

Conclusion
The SOF was reliable, especially for participants who felt a sudden chemosensory dysfunction during the outbreak. At 4 months after SARS-CoV‑2 infection, a high proportion of participants were dysosmic, whereas nearly all of them had normal taste function.
Arzneimittelnebenwirkungen und Medikationsfehler bei Kindern
Authors: Leitzen S. , Kayser C. , Weißmann K. , Sachs B. 
Published: December 2021

Zusammenfassung
Hintergrund
Kinder sind einem höheren Risiko für Nebenwirkungen (NW) und Medikationsfehler (MF) als Erwachsene ausgesetzt, auch weil es häufig an geeigneten Dosierungsempfehlungen, Arzneiformen und adäquaten Applikationsformen mangelt.

Material und Methode
Kurze Literaturübersicht und Auswertung von Spontanberichten aus der Datenbank EudraVigilance bezüglich NW zu Kindern zwischen 2000 und 2019 sowie einer Datensammlung zu MF bei Kindern zwischen 2014 und 2020 in Deutschland.

Ergebnisse
MPH als zentral wirksames Sympathomimetikum wird zur Behandlung der Aufmerksamkeitsdefizit‑/Hyperaktivitätsstörung (ADHS) eingesetzt.
Im Bewertungszeitraum 2014–2020 wurden dem Bundesinstitut für Arzneimittel und Medizinprodukte 151 MF direkt gemeldet. Häufig gemeldet wurden nicht korrekt durchgeführte Zubereitungen von Arzneimitteln, wie z. B. bei antibiotischen Trockensäften, die zu fehlerhaften Dosierungen führten.

Schlussfolgerung
Zudem sollten andere Informationsquellen (z. B. Dosierungsdatenbanken) intensiv genutzt werden, zum einen, um bereits vorhandene Informationen im klinischen und im ambulanten Setting besser umzusetzen, zum anderen, um die Kenntnisse zu Anwendungsrisiken bei Kindern zu verbessern. Diesbezüglich sollte die Meldebereitschaft der Ärzte- und Apothekerschaft zu NW und MF weiter erhöht werden.
Sobolev-to-Lipschitz property on $${\mathsf {QCD}}$$-spaces and applications
Authors: Dello Schiavo Lorenzo , Suzuki Kohei 
Published: December 2021

AbstractWe prove the Sobolev-to-Lipschitz property for metric measure spaces satisfying the quasi curvature-dimension condition recently introduced in Milman (Commun Pure Appl Math, to appear). We provide several applications to properties of the corresponding heat semigroup. In particular, under the additional assumption of infinitesimal Hilbertianity, we show the Varadhan short-time asymptotics for the heat semigroup with respect to the distance, and prove the irreducibility of the heat semigroup. These results apply in particular to large classes of (ideal) sub-Riemannian manifolds.
