Bismuth Manganese Catalysts for Soot Oxidation in Diesel Engine Exhaust: Effect of Preparation Methods on Active Oxygen Species
Authors: Li Congcong , Wang Jie , Dai Wenyue , Zhang Changsen 
Published: February 2023

AbstractTo manufacture efficient and cost‐effective catalysts for soot combustion, a series of MnxBiOy catalysts with different molar ratios of manganese bismuth (x=1,3,6,9) were prepared by hydrolysis driven redox, coprecipitation and hydrothermal synthesis methods (named R−MnxBiOy, Cop−MnxBiOy and H−MnxBiOy, respectively). The physicochemical properties of the as‐prepared catalysts were characterized via powder X‐ray diffraction (XRD), transmission electron microscope (TEM), temperature‐programmed reduction by hydrogen (H2−TPR), X‐ray photoelectron spectroscopy (XPS), and so on. The catalytic performance results show that R−Mn3BiOy catalyst obtained by hydrolysis‐driven redox method exhibited highest catalytic activity with a maximum concentration of CO2 at 390 °C (T10=330 °C, T50=385 °C, and T90=425 °C). Meanwhile, the reaction mechanism of R−Mn3BiOy catalysts was also proposed based on the characterization results. The reason for high catalytic is related to the uniform distribution of Bi on the surface of Mn, which forms more lattice defects, thereby generating a large number of oxygen vacancies and providing more active sites for catalytic reactions. This provides a reference for the design of efficient and stable soot catalysts.

Published: February 2023

AbstractIn this study, polyvinyl alcohol (PVA), gelatin (GEL) and gentamicin (GEN) were used and 13PVA/0.5GEL/GEN nanofibers were fabricated with the electrospinning method. These nanofibers were crosslinked chemically with glutaraldehyde (GA) at different time intervals (2, 3, 4, 5, 5.5 and 6 h) to observe the crosslinking effect on the properties of the nanofibers. Morphological analysis reported that as the crosslinking time increased, the nanofiber diameters also increased from 369.26 nm (non‐crosslinked) to 447.72 nm (6 h/crosslinking), respectively. The thermal characterization results demonstrated that crosslinking with different times noticeably shifted the thermal points.The tensile testing results proved that application of crosslinking enhanced the mechanical strength of the nanofibers from 3.31 MPa (non‐crosslinked) to 5.8 MPa (5.5 h/crosslinking), respectively. The GEN release profiles from the nanofibers showed similar behaviors under crosslinking and indicated that the crosslinking time did not have a significant effect on the amount of the GEN released.

Authors: Legrand Sacha , Kabir Rakib , Kärkkäinen Ari 
Published: February 2023

AbstractThe current need for polysiloxanes with high refractive index (RI) is very high because of their importance for optoelectronic applications. To meet this demand, a series of novel polysiloxanes derived from phenanthrenyl‐containing monomers, including the precursor 1‐(9‐phenanthrenyl)‐1,1,4,4,4‐pentamethoxy‐1,4‐disilabutane, are prepared using the sol‐gel technology and free‐radical polymerization. The monomer 1‐(9‐phenanthrenyl)‐1,1,4,4,4‐pentamethoxy‐1,4‐disilabutane is synthezised, purified and fully characterized including 2D‐NMR experiments for the partial assignment of both its1H and13C NMR spectra. The molecular weights of the new three‐dimentional polysiloxanes with variations in their initial molecular compositions are analyzed using gel permeation chromatography (GPC). The polysiloxanes are characterized by1H NMR spectroscopy, and obtained with high RI, thermal stabilities up to 420 °C, and excellent resistance against aging process. The polysiloxanes are coated on silicon‐wafers and gorilla glass substrates using respectively the spin‐ and bar‐coating techniques. The coated glasses show optical transmittance above 91 % with excellent hydrophobic character, refractive indexes up to 1.51, and their CIELAB coordinates are also determined. The effects of the crosslinking agent and packing density of the chains on the chemical, optical and mechanical properties of the polysiloxanes and corresponding films are studied.

Published: February 2023

AbstractRecently, anisotropic particles have attracted attention because their unique topology, functions and wide applications. Here, a new type of acrylate copolymer microspheres (AcPMs) with anisotropic wrinkled surface was synthesized with conventional monomers through two‐step self‐assembly in one‐pot with regulating reaction media. First, butyl acrylate (BA), methyl methacrylate (MMA) and methacrylic acid (MAA) were copolymerized in EtOH/H2O solvent. Second, styrene (St) and BA were further copolymerized with increasing H2O proportion in solution, which enable AcPMs with emulsifiability. Its structure and morphology were characterized by FT‐IR, SEM, XRD and DLS. The surface‐wrinkled and anisotropic AcPMs was used as carrier to conjugate with AgNPs by in‐situ reduction of silver ions (Ag+), which afforded the AcPMs conjugating AgNPs (AgNPs@AcPMs), and it presented an excellent antibacterial activity against S. aureus and E. coli. Hence, AcPMs revealed strong potential in the biomedical fields.
Construction of Amino‐Functionalized Molecularly Imprinted Silica Particles for (±)‐Ofloxacin Chiral Separation
Authors: Alatawi Raedah A. S. 
Published: February 2023

AbstractTo enantioselectively separate a (±)‐ofloxacin (OFX) racemic mixture, we describe the production and successful use of an S‐ofloxacin (S‐OFX) enantio‐selective sorbent with amino functional groups. An amide derivative was first synthesized by reacting the S‐OFX enantiomer with 3‐aminopropyltriethoxysilane (S‐OFX‐Si‐NH2). The generated S‐OFX‐Si‐NH2 derivative was then mixed with tetraethoxysilane (TEOS) and put through a base‐catalyzed sol‐gel condensation polymerization process to insert the S‐OFX enantiomeric species into the cross‐linked material. To facilitate recombination involving S‐OFX, an enantioselective gap is created by alkaline hydrolysis followed by acidification, freeing the S‐OFX from the crosslinked matrix and filling the resulting gaps with cationic ions compatible with the S‐OFX. Our chemical transformations of the monomeric precursor and the ensuing S‐OFX molecularly imprinted material (S‐OFX‐Sil) were confirmed by elemental analysis, nuclear magnetic resonance (NMR), and Fourier transform infrared spectroscopy (FTIR). In addition, scanning electron microscopy images of the sorbent surface were employed to comprehend the morphological adjustments. Both the first loading run (60 % ee of R‐OFX) and the second elution run (83 % ee of S‐OFX) using the manufactured adsorbent particles showed promising separation results.

Published: February 2023

AbstractThis report describes a new electroanalytical application for the detection of Allura Red (AR) using a carbon paste electrode (CPE) modified with lanthanide oxide and titanium oxide (LaOX‐TiOX/CPE). The standard potential (Eo) for oxidation of AR was obtained from the E (V) vs. pH relation with the regression equation Ep(V)=−0.038pH+0.922, where the intercept on the axis Ep(V) is equal to the standard potential. Moreover, the anodic peak current for AR was increased almost 160 % compared to the unmodified electrodes, and this current increase allowed us to obtain a detection limit of 0.09 μmol/L. The active surface area of the modified electrode La‐TiOX/CPE is reported for the first time in this report and was increased by almost 200 % compared to the unmodified electrodes. The usefulness of the new method was tested by analyzing real food samples with acceptable results. The real samples do not need pretreatment before analysis

Managing exploration in organizations: The effect of superior monitoring on subordinate search behavior

Published: February 2023

AbstractResearch SummaryIn this article, we explore the effects of managerial monitoring on the behavior of subordinates tasked with the search for alternatives in a complex environment. We argue that managerial monitoring will lead subordinates to exhibit more search than they would engage in otherwise as they try to impress their superiors by exerting more effort. We test and confirm our hypothesis in four laboratory studies with a total of 444 participants. Our findings show that search distance and duration are highly susceptible to managerial monitoring, whereas similar interventions from peers and subordinates are ineffective.Managerial SummaryA key task for employees is to find new solutions to corporate problems when and where they occur. But what determines how long these individuals search and how far they venture before settling on one solution eventually? And how can and should managers steer this process, particularly if they are as unknowing about potential solutions as their subordinates? Here, we show that leaders can bring their staff to explore complex solution spaces longer and more remotely by regularly appraising their subordinates' efforts. This is because employees will feel an enhanced need to demonstrate their industriousness to their bosses, and long and distant search is easily justified. Whether this increases corporate performance depends on the complexity of the solution space and the opportunity costs of search.

Published: February 2023

AbstractDrug microcarriers are widely used in disease treatment, and microfluidics is well established in the preparation of microcarrier particles. A proper design of the microfluidic platform toward scalable production of drug microcarriers can extend its application values in wound healing, where large numbers of microcarriers are required. Here, a microfluidic step emulsification method for the preparation of monodisperse droplets is presented. The droplet size depends primarily on the microchannel depth rather than flow rate, making the system robust for high‐throughput production of droplets and hydrogel microparticles. Based on this platform, basic fibroblast growth factor (bFGF) is uniformly encapsulated in the microparticles, and black phosphorus (BP) is incorporated for controllable release via near‐infrared (NIR) stimulation. The microparticles serve as drug carriers to be applied to the wound site, inducing angiogenesis and collagen deposition, thereby accelerating wound repair. These results indicate that the step emulsification technique provides a promising solution to scalable production of drug microcarriers for wound healing as well as tissue regeneration.

Published: February 2023

AbstractGlioblastoma (GBM) is the most common lethal brain tumor with dismal treatment outcomes and poor response to chemotherapy. As the regulatory center of cytogenetics and metabolism, most tumor chemotherapeutic molecules exert therapeutic effects in the nucleus. Nanodrugs showing the nuclear aggregation effect are expected to eliminate and fundamentally suppress tumor cells. In this study, a nanodrug delivery system based on polyhedral oligomeric silsesquioxane (POSS) is introduced to deliver drugs into the nuclei of GBM cells, effectively enhancing the therapeutic efficacy of chemotherapy. The nanoparticles are modified with folic acid and iRGD peptides molecules to improve their tumor cell targeting and uptake via receptor‐mediated endocytosis. Nuclear aggregation allows for the direct delivery of chemotherapeutic drug temozolomide (TMZ) to the tumor cell nuclei, resulting in more significant DNA damage and inhibition of tumor cell proliferation. Herein, TMZ‐loaded POSS nanoparticles can significantly improve the survival of GBM‐bearing mice. Therefore, the modified POSS nanoparticles may serve as a promising drug‐loaded delivery platform to improve chemotherapy outcomes in GBM patients.
Localizing Oxygen Lattice Evolutions Eliminates Oxygen Release and Voltage Decay in All‐Mn‐Based Li‐Rich Cathodes

Published: February 2023

AbstractAll‐Mn‐based Li‐rich cathodes Li2MnO3 have attracted extensive attention because of their cost advantage and ultrahigh theoretical capacity. However, the unstable anionic redox reaction (ARR), which involves irreversible oxygen releases, causes declines in cycling capacity and intercalation potential, thus hindering their practical applications. Here, it is proposed that introducing stacking‐fault defects into the Li2MnO3 can localize oxygen lattice evolutions and stabilize the ARR, eliminating oxygen releases. The thus‐made cathode has a highly reversible capacity (320 mA h g−1) and achieves excellent cycling stability. After 100 cycles, the capacity retention rate is 86% and the voltage decay is practically eliminated at 0.19 mV per cycle. Attributing to the stable ARR, samples show reduced stress–strain and phase transitions. Neutron pair distribution function (nPDF) measurements indicate that there is a structure response of localized oxygen lattice distortion to the ARR and the average oxygen lattice framework is well‐preserved which is a prerequisite for the high cycle reversibility.
Genomic evaluation of native Walleye in the Appalachian region and the effects of stocking

Published: February 2023

Abstract

Objective
Create a quicker and more accurate genetic assignment tool for Walleye Sander vitreus broodstock in the Eastern Highlands region and to quantify genetic diversity of four Walleye populations using next-generation sequencing.

Methods
To determine the impacts of stocking nonnative Great Lakes strain Walleye on local populations, three Appalachian populations were sampled: two native populations (Rockcastle River, Kentucky, and New River, Virginia) and one population founded from the Great Lakes strain (Tygart Lake, West Virginia). Walleye from Lake Erie were used as a reference for the Great Lakes strain. Utilization of a genotype-by-sequencing approach supported genome-wide estimates of genetic diversity, population structure, and creation of two single-nucleotide polymorphism assays that can be used to rapidly identify Great Lakes-strain, native Eastern Highland-strain, and F1 hybrid Walleye.

Result
Results indicate that the four populations we evaluated were genetically distinct from one another and that each population contains varying degrees of genetic differentiation relative to its source population. The stocked Tygart Lake population displayed lower genetic diversity in metrics such as nucleotide diversity (0.172 vs. 0.184), private alleles (4057 vs. 7623), and observed heterozygosity (0.163 vs. 0.204), likely indicative of genetic drift stemming from a founder effect. The two native populations displayed varying levels of genetic diversity. The New River population was found to have a higher ancestry of the Great Lakes strain in their genome than the Rockcastle River population, reflecting the known admixture of New River Walleye following historic stocking of Great Lakes-derived Walleye. Our results also identified a pure native Eastern Highlands strain population that can be used for future augmentation and restoration of Eastern Highlands Walleye.

Conclusion
Our results provide a diagnostic single-nucleotide polymorphism assay to quickly identify Great Lake strain, Eastern Highland strain, and their F1 hybrid for future management efforts and provide key population genetic insights to managers to enhance best management practices.

Published: February 2023

AbstractPhotovoltaic (PV) is one of primary renewable energy sources aimed to achieve national electrification ratio in Indonesia. There are two PV electricity generators in Indonesia, centralized PV generators (PLTS) and dispersed PV generators (SHS). Both PLTS and SHS are installed in remote and rural areas by which there are no electricity grids provided by state-owned electricity (PLN). The numbers of 15 PLTS/SHS projects are main cases of this study. All of them are categorized based on the type of project and thus analyzed by qualitative research method. This research attempts to investigate PV projects’ current progress and formulate a solution to solve the emerging problems. This research found that PLTS/ SHS projects face unresolved classical problems over the years, unsustaining PV projects (e.g., short-life infrastructure due to maintenance capability issue). This study proposes regional innovation system (RIS) and sectoral innovation system (SIS) as the Indonesian comprehensive policy strategy to sustain national PV projects. Network Governance (NG) perspective is a lens to capture how actors of academician, business, government, and community (ABGC) interact and collaborate mutually. The conclusion is that RIS and SIS can create a PV market in Indonesia, possibly being implemented through different NG forms.
Constraining higher-spin S-matrices
Authors: Tran Tung 
Published: February 2023

Abstract
There are various no-go theorems that tightly constrain the existence of local higher-spin theories with non-trivial S-matrix in flat space. Due to the existence of higher-spin Yang-Mills theory with non-trivial scattering amplitudes, it makes sense to revisit Weinberg’s soft theorem — a direct consequence of the Lorentz invariance of the S-matrix that does not take advantage of unitarity and parity invariance. By working with the chiral representation — a representation originated from twistor theory, we show that Weinberg’s soft theorem can be evaded and non-trivial higher-spin S-matrix is possible. In particular, we show that Weinberg’s soft theorem is more closely related to the number of derivatives in the interactions rather than spins. We also observe that all constraints imposed by gauge invariance of the S-matrix are accompanied by polynomials in the soft momentum of the emitted particle where the zeroth order in the soft momentum is a charge conservation law.
Azimuthal decorrelation for photon induced dijet production in ultra-peripheral collisions of heavy ions
Authors: Zhang Cheng , Dai Qian-Shun , Shao Ding Yu 
Published: February 2023

Abstract
We study the azimuthal angular decorrelation of the dijet production via photon fusion in ultra-peripheral heavy ion collisions. The impact parameter dependent cross section of quark-antiquark pairs production is derived using the equivalent photon approximation, and the contribution from final-state QCD radiations to the azimuthal angular distribution are calculated within Soft-Collinear Effective Theory. We carry out the QCD resummation of large logarithms of the azimuthal angle as well as the jet radius at next-to-leading logarithmic accuracy. In the end we present the normalized differential cross section for azimuthal decorrelation of the dijet pair and find that our results are consistent with the measurements reported by the ATLAS collaboration.
Quantum current dissipation in superconducting strings and vortons
Authors: Abe Yoshihiko , Hamada Yu , Saji Kota , Yoshioka Koichi 
Published: February 2023

Abstract
In this work, the current stability is discussed for cosmic strings with the bosonic superconductivity. A non-vanishing curvature of string generally induce the quantum instability of the current-carrying particle. Its decay rates are explored for various types of model parameters, curved string shapes, and decay processes. As a cosmological application, the stability is examined for superconducting strings in the string network and also for cosmic vortons by evaluating their cosmological evolution. The zero mode and hence the vorton cannot be stable in various cases, e.g., with a hierarchy between the current-carrying particle mass off the string and the string tension or with sizable couplings of the current-carrying particle to light species such as the Standard Model particles.

Long-lived heavy neutral leptons with a displaced shower signature at CMS
Authors: Cottin Giovanna , Helo Juan Carlos , Hirsch Martin , Peña Cristián , Wang Christina , Xie Si 
Published: February 2023

Abstract
We study the LHC discovery potential in the search for heavy neutral leptons (HNL) with a new signature: a displaced shower in the CMS muon detector, giving rise to a large cluster of hits forming a displaced shower. A new Delphes module is used to model the CMS detector response for such displaced decays. We reinterpret a dedicated CMS search for neutral long-lived particles decaying in the CMS muon endcap detectors for the minimal HNL scenario. We demonstrate that this new strategy is particularly sensitive to active-sterile mixings with τ leptons, due to hadronic τ decays. HNL masses between ~ 1–6 GeV can be accessed for mixings as low as |VτN|2~10−7, probing unique regions of parameter space in the τ sector.
