Published: May 2021

AbstractRecently emerged ionic thermoelectric conversion with the Soret effect is advantageous in providing large thermopower on the order of ≈1–10 mV K−1, but the origin of the large thermopower and the methodology of attaining superior thermoelectric performances are yet to be disclosed. Here, key parameters and their optimization for outstanding thermoelectric responses with polystyrene sulfonic acid (PSS‐H) are unveiled. It is found that the thermo‐diffusion of water boosts proton transport, playing a key role in obtaining large ionic thermopower by promoting unidirectional migration of protons from a hotter to colder side. When graphene oxide (GO) embedded in PSS‐H is aligned along the transport direction of protons and water, their diffusion along the in‐plane direction of GO is promoted, enlarging both ionic thermopower and ionic electrical conductivity. PSS‐H containing 3 wt% GO possesses extremely large ionic power factors up to 1.8 mW m−1 K−2 and ionic figure‐of‐merits up to 0.85 at 23 °C. This study provides not only preeminent thermoelectric performances based on ion transport but also identifies the influence of the key parameters on thermoelectric properties, suggesting controllability of thermo‐diffusion of ions depending on inclusions in base materials, which will draw numerous subsequent research with their alterations.
Injectability of Biosynthetic Hydrogels: Consideration for Minimally Invasive Surgical Procedures and 3D Bioprinting
Authors: Birman Tamara , Seliktar Dror 
Published: May 2021

AbstractInjectable hydrogels are often preferred when designing carriers for cell therapy or developing new bio‐ink formulations. Biosynthetic hydrogels, which are a class of materials made with a hybrid design strategy, can be advantageous for endowing injectability while maintaining biological activity of the material. The chemical modification required to make these gels injectable by specific crosslinking pathways can be challenging and also make the hydrogels inhospitable to cells. Therefore, most efforts to functionalize biosynthetic hydrogel precursors toward injectability in the presence of cells try to balance between chemical and biological functionality, in order to preserve cell compatibility while addressing the injectability design challenges. Accordingly, hydrogel crosslinking strategies have evolved to include the use of photoinitiated “click” chemistry or bio‐orthogonal reactions with rapid gelation kinetics and minimal cyto‐toxicity required when working with cell‐compatible hydrogel systems. With many new injectable biosynthetic materials emerging, their impact in cell‐based regenerative medicine and bioprinting is also becoming more apparent. This review covers the main strategies that are used to endow biosynthetic polymers with injectability through rapid, cyto‐compatible physical or covalent crosslinking and the main considerations for using the resulting injectable hydrogels in cell therapy, tissue regeneration, and bioprinting.

AbstractEarly freezes in the spring are becoming increasingly common. To protect farmers from low temperatures (LT), crops need improved LT tolerance. The hypothesis of this paper is that maize (Zea mays L.) hybrids released in the 2000s had higher LT tolerances than those released in the 1970s. In the study, eight popular maize released between 1970 and 2010 were subjected to LT in four different trials. Germination time, growth uniformity, recovery ability from LT stress, and leaf productivity at seedling stage are important indicators in evaluating LT tolerance of maize. Hybrids released in the 1970s had a higher gibberellin A3 (GA3) content in seeds, which resulted in faster germination in LT (P = .02). In contrast, plant growth uniformity of the 2000s hybrids were higher than that of the 1970s hybrids in LT (P = .00 at emergence). Upon being returned to warm temperatures, the 2000s hybrids recovered more rapidly than old ones mainly because of the larger root systems, higher GA3, and indole‐3‐acetic acid (IAA) content in seedlings. In addition, the 2000s hybrids had a higher chlorophyll content, Fv/Fm, soluble sugar and starch content, and antioxidant enzyme activity in seedlings than old hybrids in LT, which can also contribute to a fast recovery from LT stress. Based on the growth uniformity and recovery ability from LT stress, new hybrids showed a higher LT tolerance than old hybrids during early growth stage. This study showed the genetic tolerance in LT may exist in hybrids that were released 50 yr ago, and that exporting differences between hybrids possible mechanism of temperature tolerance can be identified.

AbstractSeparation of acetylene from carbon dioxide remains a daunting challenge because of their very similar molecular sizes and physical properties. We herein report the first example of using copper(I)‐alkynyl chemistry within an ultra‐microporous MOF (CuI@UiO‐66‐(COOH)2) to achieve ultrahigh C2H2/CO2separation selectivity. The anchored CuIions on the pore surfaces can specifically and strongly interact with C2H2molecule through copper(I)‐alkynyl π‐complexation and thus rapidly adsorb large amount of C2H2at low‐pressure region, while effectively reduce CO2uptake due to the small pore sizes. This material thus exhibits the record high C2H2/CO2selectivity of 185 at ambient conditions, significantly higher than the previous benchmark ZJU‐74a (36.5) and ATC‐Cu (53.6). Theoretical calculations reveal that the unique π‐complexation between CuIand C2H2mainly contributes to the ultra‐strong C2H2binding affinity and record selectivity. The exceptional separation performance was evidenced by breakthrough experiments for C2H2/CO2gas mixtures. This work suggests a new perspective to functionalizing MOFs with copper(I)‐alkynyl chemistry for highly selective separation of C2H2over CO2.

Published: May 2021

AbstractThe functionalization of C−H bonds in light alkanes, particularly to form C−N bonds, remains a challenge. We report the dehydrogenative coupling of amides with C1–C4 hydrocarbons to form N‐alkyl amide products with tBuOOtBu as oxidant, and a copper complex of a phenanthroline‐type ligand as catalyst. The reactions occurred in good yields in benzene or supercritical carbon dioxide as solvents. This strategy allowed for the determination of the relative reactivity of these alkane C−H bonds toward this amination process and showed, in contrast to prior work with larger alkanes, that the reactivity correlated with bond dissociation energies.

AbstractBased on liquid crystal elastomer (LCE) materials, hierarchically structured soft actuators can meet some requirements for “human‐friendly” working mode and execute complex tasks with intelligent adaptation to environmental changes. However, few researchers have paid much attention to the preparation methods of multicomponent/hierarchical LCE actuators. In this communication, we demonstrate the successful integration of an exchangeable diselenide chain extender for the preparation of dynamic LCEs, which could be reprogrammed on heating or under visible light illumination. Moreover, the rearrangeable polydiselenide networks could be applied to develop the self‐welding technology toward fabricating hierarchically structured LCE actuators with sophisticated deformability without using any auxiliary reagent (adhesive, tape, catalysts or initiator) during the assembling process.

AbstractWir berichten über eine 12‐stufige Totalsynthese des Naturstoffes Dysiherbol A, eines stark entzündungshemmenden und antitumoralen Avaran‐Meroterpens aus dem Meeresschwamm Dysidea sp. Als Schlüsselschritte dienen eine enantioselektive Cu‐katalysierte 1,4‐Addition mit Abfangen des Enolates, eine Gold‐katalysierte Doppelcyclisierung zum Aufbau des tetracyclischen Kohlenstoff‐Gerüsts sowie die späte Einführung der C5‐Brückenkopf‐Methylgruppe durch Protonen‐induzierte Cyclopropan‐Öffnung unter spontaner Ausbildung einer Etherbrücke. Die erhaltene pentacyclische Verbindung (entsprechend einem Anhydrid der ursprünglich für Dysiherbol A vorgeschlagenen Struktur) zeigte identische spektroskopische Daten wie der Naturstoff, jedoch einen entgegengesetzten Drehwert. CD‐spektroskopische Messungen bestätigten, dass sowohl die Konstitution als auch die absolute Konfiguration der ursprünglich für (+)‐Dysiherbol A vorgeschlagenen Struktur revidiert werden müssen.
Distributed dynamic event‐triggered control approach to multi‐agent systems via adaptive consensus protocols
Authors: Zhao Guanglei , Wei Haoxiong , Fu Xiuwei 
Published: May 2021

AbstractThis paper studies the event‐triggered consensus problem of multi‐agent system with general linear dynamics. A novel dynamic event‐triggering mechanism (ETM) is proposed, and it is formally shown that the proposed dynamic ETM can achieve larger triggering intervals than the existing ones. Then, a distributed adaptive control protocol is developed with the updating law of coupling strength. With the proposed adaptive control protocol and dynamic ETM, the event‐triggered consensus control protocol can be implemented in a fully distributed way. Moreover, Zeno behavior can be ensured to be excluded, and an algorithm is developed such that the implementation of the proposed consensus control protocol does not need continuous communication between neighboring agents. Finally, the effectiveness of the proposed methods is illustrated by a numerical example.
Stabilizing a spherical pendulum on a quadrotor

Published: May 2021

AbstractIn this article, we design a backstepping control law based on geometric principles to swing up a spherical pendulum mounted on a moving quadrotor. The available degrees of freedom in the control vector also permit us to position the plane of the quadrotor parallel to the ground. The problem addressed here is, indeed, novel and has many practical applications which arise during the transport of a payload mounted on top of a quadrotor. The modeling and control law are coordinate‐free and thus avoid singularity issues. The geometric treatment of the problem greatly simplifies both the modeling and control law for the system. The control action is verified and supported by numerical experiments for aggressive maneuvers starting very close to the downward stable equilibrium position of the pendulum.
Wilhelm Rudolf Kutter – Portrait eines Wasserbauingenieurs

Published: May 2021

AbstractBeim Studium historischer Erläuterungsberichte, wie bspw. zum Bau des Erfurter Flutgrabens in den Jahren 1890–1898, stößt man immer wieder auf die sog. „Kuttersche Formel“ und damit auf die Frage, wer eigentlich der Namensgeber dieser hydraulischen Abflussformel war. In den allgemeinen, frei zugänglichen Quellen findet man hierzu nur begrenzte Hinweise, welche im Wesentlichen den wissenschaftlich‐technischen Hintergrund erläutern. Unterzieht man sich aber der Mühe, die familiären Beziehungen über vier Generationen hinweg zu recherchieren, und hat man dabei noch das Glück, mit Samuel Kutter einen promovierten Physiker als Ururenkel zu finden, so kann man auch heute noch ein beeindruckendes Portrait von Wilhelm Rudolf Kutter nachzeichnen.

AbstractCastor protein isolate (CPI) was prepared by aqueous solubilization of defatted castor kernel meal under alkaline conditions (pH 12.0), with precipitation at the isoelectric point (pH 5.0) followed by heat treatment. Five experimental diets were prepared by substituting soybean protein isolate (SPI) at 0%, 25%, 50%, 75%, and 100% with CPI based on protein equivalent basis. The diets were assigned as control, PI25, PI50, PI75, and PI100, respectively. A 60‐day feeding trial was conducted following a completely randomized design. Results revealed significant improvement in growth rates, feed conversion, and protein retention in Labeo rohita fingerlings (P < 0.05) at 124.50 g CPI kg−1 diet (PI75). However, these were similar between control and PI100 (P > 0.05). Dietary CPI did not alter the hepatosomatic index, viscerosomatic index, survival, carcass composition (except crude protein), and digestive enzymes (P > 0.05). The metabolic enzymatic profile of rohu fingerlings was significantly affected due to dietary treatments (P < 0.05) but oxidative stress enzymes were not affected by feeding of CPI. The activity of the aminotransferases, lactate dehydrogenase, and malate dehydrogenase did not differ (P > 0.05) between control and PI100. The preparation of protein isolate is therefore a way forward for the effective valorization of toxic castor meal and could be used at 164.0 g kg−1 inclusion (complete substitution of soybean protein isolate) in the diet of L. rohita. © 2021 Society of Industrial Chemistry and John Wiley & Sons Ltd.
Characteristics of quantifiers moderate the framing effect

Published: May 2021

AbstractThe attribute framing effect, where people judge a quantity of an item more positively with a positively described attribute (e.g., “75% lean”) than its negative, albeit normatively equivalent description (e.g., “25% fat”), is a robust phenomenon, which may be moderated under certain conditions. In this paper, we investigated the moderating effect of the characteristics of the quantifier term: its format (verbal, e.g., “high,” or numerical, e.g., “75%”) and magnitude (i.e., if it is a small or large quantity) using positive or negative synonyms of attributes (e.g., energy vs. calories). Over five pre‐registered studies using a 2 (synonym, between‐subjects: positive or negative) × 2 (quantifier format, between‐subjects: verbal or numerical) × 2 (quantifier magnitude, within‐subjects: small or large) mixed design, we manipulated quantifier format and magnitude orthogonally for synonyms with differing valence. We also tested two mechanisms for the framing effect: whether the effect was mediated by the affect associated with the frame and whether participants inferred the speaker to be positive about the target. We found a framing effect with synonyms that was reversed in direction for the small (vs. large) quantifiers, but not significantly moderated by quantifier format. Both the affect associated with the frame and the inferred level of speaker positivity partially mediated the framing effect, and the level of mediation varied with quantifier magnitude. These results suggest that the magnitude of the quantifier modifies one's evaluation of the frame, and the mechanism for people's evaluations in a framing situation may differ for small and large quantifiers.

AbstractPreviously compound 12 showed great anti‐trypanosome activity without toxicity in an in vivo study. In the current study, a sensitive and rapid high‐performance liquid chromatography–tandem mass spectrometry (HPLC–MS/MS) method was developed and validated to investigate its pharmacokinetics in mouse plasma. A protein precipitation method was applied to extract the compound, and it was then separated using a Kinetex C18 column with mobile phase consisting of acetonitrile–0.1% formic acid water (50:50, v/v) at a flow rate of 300 μl/min. The analytes were detected with the multiple reaction monitoring in negative electrospray ionization source for quantitative response of the compounds. Compound 12 was detected at m/z 477.0 → 367.2, while the internal standard compound 14 was detected at m/z 499.2 → 268.2. Inter‐ and intra‐day precision was <5.22 and 2.79% respectively, while the accuracy range was within ±9.65%. The method was successfully applied to evaluate the pharmacokinetics of compound 12 in mouse plasma with two formulations (20% Cremophor EL or sesame oil) and drug administration routes (oral and intraperitoneal injection). We observed a better drug serum concentration with the Cremophor formulation, and the two different drug administration routes did not show significant differences from the drug distribution.

AbstractAbnormal energy metabolism, including enhanced aerobic glycolysis and lipid synthesis, is a well‐established feature of glioblastoma (GBM) cells. Thus, targeting the cellular glycolipid metabolism can be a feasible therapeutic strategy for GBM. This study aimed to evaluate the roles of MSI2, SNORD12B, and ZBTB4 in regulating the glycolipid metabolism and proliferation of GBM cells. MSI2 and SNORD12B expression was significantly upregulated and ZBTB4 expression was significantly low in GBM tissues and cells. Knockdown of MSI2 or SNORD12B or overexpression of ZBTB4 inhibited GBM cell glycolipid metabolism and proliferation. MSI2 may improve SNORD12B expression by increasing its stability. Importantly, SNORD12B increased utilization of the ZBTB4 mRNA transcript distal polyadenylation signal in alternative polyadenylation processing by competitively combining with FIP1L1, which decreased ZBTB4 expression because of the increased proportion of the 3′ untranslated region long transcript. ZBTB4 transcriptionally suppressed the expression of HK2 and ACLY by binding directly to the promoter regions. Additionally, ZBTB4 bound the MSI promoter region to transcriptionally suppress MSI2 expression, thereby forming an MSI2/SNORD12B/FIP1L1/ZBTB4 feedback loop to regulate the glycolipid metabolism and proliferation of GBM cells. In conclusion, MSI2 increased the stability of SNORD12B, which regulated ZBTB4 alternative polyadenylation processing by competitively binding to FIP1L1. Thus, the MSI2/SNORD12B/FIP1L1/ZBTB4 positive feedback loop plays a crucial role in regulating the glycolipid metabolism of GBM cells and provides a potential drug target for glioma treatment.
Development of 100 kHz optical pumped atomic magnetometer module for non‐magnetic shield
Authors: Takeda Shun , Kumagai Hiroshi , Nebuya Satoru 
Published: May 2021

AbstractIn recent years, various sensors for biomagnetic measurement have been researched and developed. These are mainly for low frequency small signals such as magnetocardiography. Optical pumped atomic magnetometer (OPAM) would rather be applicable to this high frequency signal since there is a valid signal at higher frequencies. However, the highly sensitive OPAM uses a magnetic shield and an anti‐vibration table, which makes the OPAM system larger. By packing the optical system in one case, you can develop an OPAM module that can measure even while moving. As a result, by using a phase‐locked loop, we have achieved a sensitivity of 2.548 pT/Hz1/2 for a 100 kHz magnetic signal in the presence of a bias magnetic field and electromagnetic noise.
