Published: January 2021

AbstractConsiderable work has gone into the development of synthetic systems that mimic biological approaches to provide adhesion in a wide range of environments. The catechol group is a workhorse functional group for this approach, capable of promoting adhesion through a number of transient interactions and oxidation states. We previously reported the development of a family of acrylate‐maleimide‐catechol (PAM) copolymers that varied the side chain to govern thermal properties and polarity. Here, we have used aluminium adherends to study the performance of the PAM series in an adhesive application, employing different deposition techniques to access ‘true’ and plasticized Tgs for the material. The polarity and effective Tg of the polymers had little correlation with the observed strength of adhesion, although some conclusions could be drawn about the series based on postmortem analysis and morphology characterization, where side chain assembly led to some periodic organization of the films. Adhesive strength to the adherends was sufficient to overcome the strength of the PAM, leading to a cohesive failure mode. Overall, the study revealed the importance of processing conditions and conditioning in the evaluation of novel polymer compositions. Published 2021.

One‐step production of polyelectrolyte nanoparticles
Authors: Vauthier Madeline , Serra Christophe Alexandre 
Published: January 2021

AbstractNeutral polymeric nanoparticles have found many important applications in fields such as drug delivery, biosensing and environmental research. However, charged polymeric nanoparticles have not yet found such success mainly due to the multi‐step and time‐consuming conventional production route. An emulsification–evaporation method was described as a fast and reproducible way to obtain neutral polymeric nanosuspensions. We propose here, for the first time, to extend this method to the one‐step production of negatively charged polymeric nanoparticles. For this purpose, we compared different processes, namely sonication, shear mixing and elongational‐flow micromixing (μRMX), in order to produce polyelectrolyte nanoparticles (PNPs) of poly(styrene sulfonate). We found that only μRMX allowed the production of highly monodispersed PNPs. We also verified the decrease of nanoparticle size (from 300 to 150 nm) and polydispersity index by increasing the emulsification time and decreasing the polymer molecular weight. Finally, we observed and explained the causes of an unusual behavior: the sudden increase of PNP size after a given emulsification time when using μRMX. © 2021 Society of Chemical Industry
Registration of ‘UA248’ cotton cultivar
Authors: Bourland Fred M. , Jones Don C. 
Published: January 2021

Abstract‘UA248’ (Reg. no. CV‐145, PI 693756) is a conventional cultivar of cotton (Gossypium hirsutum L.) that was released by the Arkansas Agricultural Experiment Station in March 2020. In 2008, UA48 was crossed with Arkot 0016 with the goal of developing a line having fiber quality of UA48 but with improved yields and broadened adaptation. Over 5 yr of Arkansas tests, lint yields of UA248 were 10–15% higher than UA48 at four locations. Fiber quality of UA248 approaches that of UA48. In most tests, the fiber length, length uniformity, and strength of UA248 exceeded most entries except UA48. Micronaire of UA248 is comparable to DP 393 and finer than UA48. UA248 is an early maturity cultivar but matures slightly later than UA48. UA248 displays high resistance to bacterial blight and is equal to DP 393 in response to other diseases. UA248 combines fiber quality traits comparable to UA48 and enhanced yielding ability.

Atmospheric‐pressure plasma actuators: Enhancement of the free charges' transport mechanism
Authors: Ricchiuto Anna Chiara , Borghi Carlo Angelo , Cristofolini Andrea , Neretti Gabriele 
Published: January 2021

AbstractCharge particles can increase the biocidal efficacy of nonthermal plasmas in indirect treatments. The aim of this study is to increase the amount of free charges produced and delivered by a surface dielectric barrier discharge fluid‐dynamics actuator. Different linear actuators and supplying conditions have been considered. Actuators were utilized to produce an ionic wind impinging an insulating target surface. Charged particles' distribution over the target was measured with and without a metallic mesh between the actuator and target itself. Linear actuators have proven to be more effective in charge delivery with respect to an annular one previously studied by our research team. A two‐dimensional electrostatic finite‐element analysis has been carried out to get a better insight into this physical behavior.

AbstractBACKGROUNDLong non‐coding RNAs (lncRNAs) play important roles in the regulation of biological processes and have been identified in many species including insects. However, the association between lncRNAs and pesticide resistance in insect species such as Bactrocera dorsalis is unknown.RESULTSRNA‐seq was performed on malathion resistant (MR1) and susceptible (MS) strains of B. dorsalis and a total of 6171 lncRNAs transcripts were identified. These included 3728 lincRNAs, 653 antisense lncRNAs, 1402 intronic lncRNAs, and 388 sense lncRNAs. A total of 40 and 52 upregulated lncRNAs were found in females and males of the MR1 strain compared to 54 and 49 in the same sexes of the MS strain, respectively. Twenty‐seven of these lncRNAs showed the same trend of expression in both females and males in the MR1 strain, in which 15 lncRNAs were upregulated and 12 were downregulated. RT‐qPCR results indicated that the differentially expressed lncRNAs were associated with malathion resistance. The lnc15010.10 and lnc3774.2 were highly expressed in the cuticle of the MR1 strain, indicating that these two lncRNAs may be related to malathion resistance. RNAi of lnc3774.2 and a bioassay showed that malathion resistance was possibly influenced by changes in the B. dorsalis cuticle.CONCLUSIONLncRNAs of B. dorsalis potentially related to the malathion resistance were identified. Two lncRNAs appear to influence malathion resistance via modulating the structure, or components, of the cuticle. © 2021 Society of Chemical Industry
Entomopathogenic nematodes for control of carrot weevil: efficacy and longevity in muck and mineral soils
Authors: Blatt Suzanne , McDonald Mary Ruth , Mlynarek Julia 
Published: January 2021

AbstractBACKGROUNDCarrot weevil is an important pest throughout carrot‐producing regions in Canada. Pesticides to control carrot weevil adults require application when the majority of adults have emerged and often this occurs after oviposition has already commenced and damage will be realized. One alternative to conventional pesticides are entomopathogenic nematodes. We studied four commercially available entomopathogenic nematode products (Steinernema feltiae, S. carpocapsae, S. kraussei and Heterorhabditis bacteriophora) for efficacy against carrot weevil in Nova Scotia and Ontario carrot fields in 2017 and 2018. The longevity and infectivity of the products in fine sandy loam soil (Ontario) and sandy loam soil (Nova Scotia) were evaluated using Galleria mellonella larvae.RESULTSIn Nova Scotia soils, only S. kraussei when applied twice, showed some efficacy to reduce damage from carrot weevil in 2017. In Ontario, an early application of H. bacteriophora and S. feltiae significantly reduced the percentage of carrots with weevil damage in 2018. Longevity and infectivity of S. carpocapsae and S. feltiae (against G. mellonella) was obtained up to 6 weeks post application in Nova Scotia in 2017. Similarly, S. feltiae showed infectivity up to 9 weeks post application in Ontario and Nova Scotia in 2018.CONCLUSIONEntomopathogenic products showed an ability to survive and remain infective for up to 9 weeks in soils without irrigation. Timing of application to effect control of carrot weevil requires further study. The influence of soil moisture on the longevity and infectivity of these products is discussed. © 2021 Her Majesty the Queen in Right of Canada International Pest Management Science © 2021 Society of Chemical Industry.

Behavioral and physiological responses of Drosophila melanogaster and D. suzukii to volatiles from plant essential oils
Authors: Wang Qiang , Xu Peng , Sanchez Simon , Duran Phil , Andreazza Felipe , Isaacs Rufus , Dong Ke 
Published: January 2021

AbstractBACKGROUNDInsects rely on their sense of smell to locate food and hosts, find mates and select sites for laying eggs. Use of volatile compounds, such as essential oils (EOs), to repel insect pests and disrupt their olfaction‐driven behaviors has great practical significance in integrated pest management. However, our knowledge on the olfaction‐based mechanisms of EO repellency is quite limited.RESULTSWe evaluated the repellency of peppermint oil and nine plant EO components in Drosophila melanogaster, a model insect for olfaction study, and D. suzukii, a major fruit crop pest. All nine volatiles, menthone, (−)‐menthol, menthyl acetate, (R)‐(+)‐limonene, nerol, (+)‐fenchone, (−)‐α‐thujone, camphor, norcamphor and peppermint oil, elicited repellency in D. melanogaster in a dose‐dependent manner. Most of the compounds, except camphor, also elicited repellency in D. suzukii. Menthone, (R)‐(+)‐limonene and (+)‐fenchone were the most potent repellents against D. suzukii. Repellency was reduced or abolished in two D. melanogaster mutants of the odorant receptor co‐receptor (Orco), indicating that the observed repellency is odorant receptor (Or)‐mediated. Repellency by peppermint oil, menthone, (R)‐(+)‐limonene, (−)‐α‐thujone and norcamphor also involves Or‐independent mechanism(s). Single sensillum recording from both species revealed that common and distinct Ors and olfactory receptor neurons were activated by these compounds.CONCLUSIONSThe tested plant EO components evoke repellency by activating multiple Ors in both Drosophila species. Our study provides a foundation for further elucidation of the mechanism of EOs repellency and species‐specific olfactory adaptations. © 2021 Society of Chemical Industry
End‐substituted thiahelicenes for electronic device applications
Authors: Kumar Rahul , Maity Dilip Kumar 
Published: January 2021

AbstractMinimum energy structures of neutral and radical cations of end‐substituted thia[n]helicenes (n = 1‐10) in DCM solvent are reported. For both neutral and radical cations of these helicenes, calculated structures are nonplanar for n = 3 to 10. Helical structures are obtained for higher helicenes, and the thia[8]helicene system has a helical structure with one complete turn. Equilibrium structures are predicted by using B3LYP‐D/6‐311++G(d,p) method in conjunction with the solvation model based on solute density. Single‐point energy calculations are also performed at the MP2 level to improve certain energy parameters. Excited‐state calculations are performed using time‐dependent density functional theory formalism to predict UV‐Visible spectra of neutral and radical cations of thia[n]helicenes in DCM solvent. Thia[n]helicenes radical cation have strong absorption in the near‐infrared region. Calculations also suggest that dimerization is not a favorable process in the DCM solvent for the end‐substituted neutral and radical cation of thia[7]helicene. The present theoretical study examines the molecular and electronic properties of thia[n]helicenes in search of near‐infrared electronic devices.

Published: January 2021

AbstractMobile Großgeräte sind für die globale Wirtschaft von großer Bedeutung. Zunehmend werden sie aufgrund immer knapper werdender Rohstoffe in seismisch aktiven Gebieten, in denen noch Vorräte schlummern, eingesetzt. Das seismische Verhalten dieser nicht verankerten Strukturen unterscheidet sich durch die Möglichkeit des Abhebens grundlegend von konventionellen Bauwerken und eine zutreffende und wirtschaftliche erdbebengerechte Auslegung ist nach derzeit geltenden Erdbebennormen weltweit kaum möglich. In diesem Beitrag wird das Verhalten typischer schienengebundener mobiler Großgeräte der Fördertechnik bei Erdbeben am Beispiel von Schaufelradgeräten exemplarisch in seinen Grundsätzen untersucht, analysiert und daraus resultierend grundsätzliche Bemessungsempfehlungen für schienengebundene mobile Großgeräte der Fördertechnik gegeben. Das numerische Berechnungsmodell wird anhand von Schwingungsmessungen an realen Geräten validiert.
Intelligent antithrombotic nanomedicines: Progress, opportunities, and challenges
Authors: Xu Junchao , Zhang Yinlong , Nie Guangjun 
Published: January 2021

AbstractAntithrombotic therapy has long been a trade‐off between antithrombotic effects and hemorrhagic risk. With the aid of nanotechnology, antithrombotic drugs have realized and will further realize highly controllable targeting, disease microenvironment responsive release, imaging‐guided treatment, and reversal agents’ development in parallel with novel antithrombotics. Preclinical studies have indicated that intelligent antithrombotic nanomedicines show potential in preventing hemorrhagic risk, evading the balancing act of current antithrombotic treatments. However, none of these nanomedicines have come into clinical trials. In this review, we present a strategic summary of the field of nanoantithrombotics, which is needed to guide the design and application of the next generation of antithrombotic nanomedicines. Herein, we present the recent progress in the preclinical studies of this field, which can be divided into three categories: fibrinolytic, anticoagulant, and antiplatelet therapies. In addition, we provide an outlook on how future antithrombotic nanomedicine design can better overcome the current translational challenges for clinical use.
Optimization of soil aquifer treatment (SAT) operation using a reactive transport model
Authors: Ben Moshe Shany , Weisbrod Noam , Furman Alex 
Published: January 2021

AbstractIn this work, a numerical model was developed with the aim to study the effect of drying period (DP) duration on the biogeochemical state of a soil aquifer treatment (SAT) system, and to enhance its functionality accordingly. The model was calibrated and verified using data series from long‐column experiments, and sensitivity analysis was performed. Considering unsaturated water flow, air movement, solute transport, and the main microbial‐mediated kinetic reactions relevant to SAT, we examined outflow quality and reaction rates in response to seven DP durations while the flooding period (FP) durations were kept constant. The results show that extension of the aerobically active region occurs in response to longer DPs and suggest that very long DPs (>3 times the FPs) may not pose further advantage compared with medium‐length DPs (2.5–3 times the flooding periods). A simple optimization process was demonstrated for the experimental SAT system presented, considering outflow quality vs. infiltrated volume. An optimum was obtained at DP/FP ratio of ∼2.8. Although these results are system specific, similar biogeochemical models may be modified and used for hydraulic operation optimization in other SAT sites.

Published: January 2021

AbstractBioelectronic medicine aims to interface electronic technology with biological components and design more effective therapeutic and diagnostic tools. Advances in nanotechnology have moved the field forward improving the seamless interaction between biological and electronic components. In the lab many of these nanobioelectronic devices have the potential to improve current treatment approaches, including those for cancer, cardiovascular disorders, and disease underpinned by malfunctions in neuronal electrical communication. While promising, many of these devices and technologies require further development before they can be successfully applied in a clinical setting. Here, we highlight recent work which is close to achieving this goal, including discussion of nanoparticles, carbon nanotubes, and nanowires for medical applications. We also look forward toward the next decade to determine how current developments in nanotechnology could shape the growing field of bioelectronic medicine.This article is categorized under:Therapeutic Approaches and Drug Discovery > Emerging TechnologiesNanotechnology Approaches to Biology > Nanoscale Systems in BiologyDiagnostic Tools > Biosensing
Chemical speciation in Gd−Cd−M (M=Zn, Au) quasicrystal approximants
Authors: Gebresenbut Girma H. , Pay Gómez Cesar , Eriksson Lars , Häussermann Ulrich 
Published: January 2021

AbstractWe investigated the effect of partial replacement of Cd by M=Au and Zn in the crystal structure of the 1/1 Tsai‐type quasicrystal approximant (AC) GdCd6. Compositionally homogeneous single crystal samples Gd(Cd0.87Zn0.13(1))6and Gd(Cd0.80Au0.20(1))6were grown from melts Gd5(Cd0.8Zn0.2)100and Gd1(Cd0.9Au0.1)100, respectively, and isolated by centrifugation. The M for Cd substitution in GdCd6is accompanied with a sizeable reduction of the cubic unit cell parameter, from 15.514(2) Å to 15.329(1) Å (Zn) and 15.314(1) Å (Au). Site preferences were established from single crystal X‐ray diffraction data. A clear preference of atomic sites for Au and Zn is noted which is compared to earlier reported Yb(Cd0.75Mg0.25)6. Three and two out of in total seven crystallographic sites defining the Cd partial structure accept preferably metals more and less electronegative than Cd, respectively, and are classified as negatively and positively polarized sites in the binary 1/1 AC.
Phenomenology of vector-like leptons with Deep Learning at the Large Hadron Collider
Authors: Freitas Felipe F. , Gonçalves João , Morais António P. , Pasechnik Roman 
Published: January 2021

AbstractIn this paper, a model inspired by Grand Unification principles featuring three generations of vector-like fermions, new Higgs doublets and a rich neutrino sector at the low scale is presented. Using the state-of-the-art Deep Learning techniques we perform the first phenomenological analysis of this model focusing on the study of new charged vector-like leptons (VLLs) and their possible signatures at CERN’s Large Hadron Collider (LHC). In our numerical analysis we consider signal events for vector-boson fusion and VLL pair production topologies, both involving a final state containing a pair of charged leptons of different flavor and two sterile neutrinos that provide a missing energy. We also consider the case of VLL single production where, in addition to a pair of sterile neutrinos, the final state contains only one charged lepton. We propose a novel method to identify missing transverse energy vectors by comparing the detector response with Monte-Carlo simulated data. All calculated observables are provided as data sets for Deep Learning analysis, where a neural network is constructed, based on results obtained via an evolutive algorithm, whose objective is to maximise either the accuracy metric or the Asimov significance for different masses of the VLL. Taking into account the effect of the three analysed topologies, we have found that the combined significance for the observation of new VLLs at the high-luminosity LHC can range from 5.7σ, for a mass of 1.25 TeV, all the way up to 28σif the VLL mass is 200 GeV. We have also shown that by the end of the LHC Run-III a 200 GeV VLL can be excluded with a confidence of 8.8 standard deviations. The results obtained show that our model can be probed well before the end of the LHC operations and, in particular, providing important phenomenological information to constrain the energy scale at which new gauge symmetries emergent from the considered Grand Unification picture can be manifest.
Leading-color two-loop QCD corrections for three-photon production at hadron colliders
Authors: Abreu S. , Page B. , Pascual E. , Sotnikov V. 
Published: January 2021

Abstract
We compute the two-loop helicity amplitudes for the production of three photons at hadron colliders in QCD at leading-color. Using the two-loop numerical unitarity method coupled with analytic reconstruction techniques, we obtain the decomposition of the two-loop amplitudes in terms of master integrals in analytic form. These expressions are valid to all orders in the dimensional regulator. We use them to compute the two-loop finite remainders, which are given in a form that can be efficiently evaluated across the whole physical phase space. We further package these results in a public code which assembles the helicity-summed squared two-loop remainders, whose numerical stability across phase-space is demonstrated. This is the first time that a five-point two-loop process is publicly available for immediate phenomenological applications.
