Authors: Sabzeghabae Ariana Nushin , Berrospe‐Rodriguez Carla , Wu Chaolumen , Mangolini Lorenzo , Aguilar Guillermo 
Published: November 2022

AbstractTitanium nitride nanoparticles have become a research interest due to their distinguished optical and photothermal properties. Furthermore, the search for nanoparticle solutions with tunable nonlinear optical properties for laser‐based applications is critical. More specifically, third order optical nonlinearities such as reverse saturable absorption, optical liming, and self‐focusing are important in the biomedical and electronics fields. The optical nonlinearities of titanium nitride plasmonic nanoparticles are investigated as a function of material concentration in water solutions. Furthermore, the effect of nanoparticle clustering on optical nonlinearities is investigated by fabricating micrometer‐sized clusters of ≈50 nm titanium nitride particles. These studies demonstrate that the nonlinear absorption coefficient increases linearly with concentration. However, clusters require higher concentrations compared to the freestanding nanoparticles to exhibit similar nonlinear absorption coefficient and optical density. Similarly, the optical limiting threshold for titanium nitride nanoparticles appears to be lower compared to the cluster solutions, which is impacted by the collective scattering of nanoparticles and high reverse saturable absorption. In addition, self‐focusing is observed in the continuous resonant regime. This study provides an in‐depth analysis of the nonlinear optical properties of titanium nitride, with relevant consequences for applications such as sensor protection and photothermal therapy.
Impact of Small Scale Storage and Intelligent Scheduling Strategy on Cost Effective and Voltage Secure Operation of Wind+PV+Thermal Hybrid System
Authors: Dauda Alpesh Kumar , Panda Ambarish 
Published: November 2022

AbstractThe growing concern on climate change and environmental pollution has created enormous pressure on shifting the generation toward cleaner and environmental friendly sources. Among different clean energy producers, wind power and solar photovoltaic (PV) systems are the most attractive ones due to their abundant availability, substantial power production capability, and cost effective attributes. But, their intermittent availability makes the system operation extremely vulnerable. Therefore, optimum utilization of renewable energy in hybrid power system (HPS) may not be achievable without the integration of energy storage facilities. In this context, integration of battery energy storage (BES) systems with Wind+PV+Thermal (WPT) hybrid configuration is considered in this work to meet the sudden and short term disharmony between actual and available renewable power output. Moreover, to maintain a secure system voltage of the WPT+BES system, the impact of reactive power (Q) capability of doubly fed induction generator has also been analyzed. The scheduling problem of the proposed HPS is solved by formulating in an optimization framework. Intelligent technique is applied to evaluate the optimal operational paradigm at multiple percentage of renewable energy penetration scenarios at which the proposed HPS may operate in a voltage secure and cost effective manner. The validation of the proposed operating strategy on the comparative performance evaluation of WPT and WPT+BES systems is portrayed on IEEE30 bus benchmark power system configuration.
Behavioral framing and consumer acceptance of new food technologies: Factors influencing consumer demand for active packaging
Authors: Just David R. , Goddard Julie M. 
Published: November 2022

AbstractWe examine consumer willingness to pay (WTP) for foods packaged using active packaging which can be used to improve quality, shelf life, or safety of a range of products, potentially reducing the use of food additives (preservatives) and food waste. We administer an experimental survey of US food consumers (n = 2325) with five treatments. The surveys include contingent valuation exercises to assess consumer WTP for six products in active packaging relative to conventional packaging. We find that consumer acceptance of this technology is dependent on the product packaged and related directly to the specific relative benefit. In addition, consumer WTP is impacted by the framing of the technology in relation to other available technologies, information about the developer of the technology, and the degree of specificity of information regarding benefits. Notably, impacts of framing and use cases are primarily apparent among those who are resistant to the technology. A cluster analysis finds that those more likely to resist the technology include households that are lower income, less educated, and more likely to be white [EconLit citations: Q18, M31, D12, D83].

Published: November 2022

AbstractPlasmon‐enhanced electrochemiluminescence (ECL) at the single‐nanoparticle (NP) level was investigated by ECL microscopy. The Au NPs were assembled into an ordered array, providing a high‐throughput platform that can easily locate each NP in sequential characterizations. A strong dependence of ECL intensity on Au NP configurations was observed. We demonstrate for the first time that at the single‐particle level, the ECL of Ru(bpy)32+‐TPrA was majorly quenched by small Au NPs (<40 nm), while enhanced by large Au ones (>80 nm) due to the localized surface plasmon resonance (LSPR). Notably, the ECL intensity was further increased by the coupling effect of neighboring Au NPs. Finite Difference Time Domain (FDTD) simulations conformed well with the experimental results. This plasmon enhanced ECL microscopy for arrayed single NPs provides a reliable tool for screening electrocatalytic activity at a single particle.

Published: November 2022

AbstractIodine is widely used as an antimicrobial reagent for water disinfection in the wilderness and outer space, but residual iodine and iodide need to be removed for health reasons. Currently, it is challenging to remove low concentrations of iodine and iodide in water (≈5 ppm). Furthermore, the remediation of iodine and iodide across a broad temperature range (up to 90 °C) has not previously been investigated. In this work, we report a nitrate dimer‐directed synthesis of a single‐crystalline ionic hydrogen‐bonded crosslinked organic framework (HCOF‐7). HCOF‐7 removes iodine and iodide species in water efficiently through halogen bonding and anion exchange, reducing the total iodine concentration to 0.22 ppm at room temperature. Packed HCOF‐7 columns were employed for iodine/iodide breakthrough experiments between 23 and 90 °C, and large breakthrough volumes were recorded (≥18.3 L g−1). The high iodine/iodide removal benchmarks recorded under practical conditions make HCOF‐7 a promising adsorbent for water treatment.

Authors: Zeng Yang , Quan Qinzhi , Wen Peng , Zhang Zexi , Chen Mao 
Published: November 2022

AbstractPhoto‐controlled polymerizations are attractive to tailor macromolecules of complex compositions with spatiotemporal regulation. In this work, with a convenient synthesis for trifluorovinyl boronic ester (TFVB), we report a light‐driven organocatalyzed copolymerization of vinyl monomers and TFVB for the first time, which enabled the controlled synthesis of a variety of hybrid fluorine/boron polymers with low dispersities and good chain‐end fidelity. The good behaviors of “ON/OFF” switch, chain‐extension polymerizations and post‐modifications further highlight the versatility and reliability of this copolymerization. Furthermore, we demonstrate that the combination of fluorine and boron could furnish copolymer electrolytes of high lithium‐ion transference number (up to 0.83), bringing new opportunities of engineering high‐performance materials for energy storage purposes.

Published: November 2022

AbstractSolid electrolyte interphase (SEI) has received considerable attention due to its vital role in stabilizing Li anode. However, native and many artificial SEIs often suffer from cracking and fragmentation under dendrite impact or long‐term repeated volume variation, causing capacity decay. Herein, a mechanically interlocked network (MIN) was innovatively designed as interfacial layer to protect Li anode by incorporating the unique energy dissipation capability, which helps Li anode survive repeated volume variation during long‐term cycling. As a result, symmetric cell with MIN‐coated Li anode (MIN@Li) exhibited prolonged cycling life of 1500 hours at 1 mA cm−2. The full cell using LFP cathode (13.5 mg cm−2) cycled stably for 500 cycles with capacity retention over 88 % (1 C). Our results highlight a creative application of MIN in Li anode, and its unique energy dissipation capability promises future success in other battery fields suffering from repeated volume variations.

Published: November 2022

AbstractWhite circularly polarized organic light‐emitting diodes (CP‐WOLEDs) are of great significance in potential lighting sources and full‐color 3D displays. However, High‐performance white CP‐EL sources are almost unexplored. We have constructed full‐color CP‐EL devices based on chiral co‐assemblies by using three achiral conjugated pyrene‐based dyes (BP, w‐WP and c‐WP) doped with chiral binaphthyl‐based enantiomers (S‐/R‐M) as the EMLs through an intermolecular chirality induction mechanism. (S‐/R‐M)0.2‐(c‐WP)0.8 films exhibit regular helix nanofibers under annealing treatment and emit strong white CPL. Significantly, remarkable CP‐WOLEDs based on (S‐/R‐M)0.2‐(c‐WP)0.8 were achieved with |gEL| values as high as 6.2×10−2 and an excellent CRI of 98 at the CIE coordinates of (0.33, 0.33). These are the highest gEL and CRI values of reported CP‐WOLEDs to date. This is the first achievement of CP‐WOLEDs based on chiral co‐assembled helix nanofiber emitters, and provides a valuable strategy with which to develop white CP‐EL for future practical applications.

AbstractAgonists of innate pattern recognition receptors such as toll‐like receptors (TLRs) prime adaptive anti‐tumor immunity and hold promise for cancer immunotherapy. However, small‐molecule TLR agonists cause immune‐related adverse effects (irAEs) after systemic administration. Herein, we report a polymeric nano‐immunomodulator (cN@SS‐IMQ) that is inactive until it is selectively metabolized to an active immunostimulant within the tumor. cN@SS‐IMQ was obtained via self‐assembly of a cyclo(Arg‐Gly‐Asp‐D‐Phe‐Lys)‐modified amphiphilic copolymeric prodrug. Upon systemic administration, cN@SS‐IMQ preferentially accumulated at tumor sites and responded to high intracellular glutathione levels to release native imidazoquinolines for dendritic cell maturation, thereby enhancing the infiltration of T lymphocytes. Collectively, cN@SS‐IMQ tends to activate the immune system without irAEs, thus suggesting its promising potential for safe systemic targeting delivery.
Temperature‐Controlled Mechanochemistry Unlocks the Nickel‐Catalyzed Suzuki–Miyaura‐Type Coupling of Aryl Sulfamates at Different Scales
Authors: Reynes Javier F. , García Felipe 
Published: November 2022

AbstractSeveral mechanochemically heated processes have been published in recent years. However, precise control over the mechanochemical catalysed coupling reactions remained elusive. A recent report from Leitch, Browne and co‐workers demonstrated how a programmable jar heater manifold delivers an efficient methodology for the Suzuki–Miyaura‐type cross coupling reaction of aryl sulfamates and aryl boronic acid species. This methodology can be readily upscaled 200‐fold using twin‐screw extrusion methodologies.
Dynamic bond exchangeable thermoset vitrimers in 3D‐printing
Authors: Krishna Kumar Balaji , Dickens Tarik J. 
Published: November 2022

AbstractDynamic bond exchanging vitrimers have emerged recently due to their malleability, self‐heal ability, recyclability, and mechanical stability. Likewise, 3D printing is consciously introduced at different platforms for ease of fabrication, high throughput, cost‐effectiveness, and waste reduction. These two distinctive techniques have recently made their consensus performance, resulting from a phenomenal change in the printing field. Conventionally, thermoplastic inks have been primarily used in 3D printing, owing to their effortless processability. At the same time, thermosets were utilized for their superior mechanical strength. However, these two essential properties have been required to be presented in the printed material. In that scenario, thermoset vitrimer materials have been introduced in 3D printing, where malleability and mechanical stability have been observed in the same material. Thus, this article details the recent vitrimer material included with the different 3D printing system systems with their reported results to understand and make them widespread. Eventually, the outlook and perspectives could be helpful to understand and enhance this specific field.
Synthesis of poly(lactide‐co‐glycolide) containing high glycolide contents by ring‐opening polymerization as well as their structural characterizations, thermal properties, morphologies, and hydrophilicity
Authors: Phan Van Hoang‐Khang , Tai Yi‐Hsin , Chiang Tai‐Chin , Yu Chin‐Yang 
Published: November 2022

AbstractRandom copolymers, poly(l‐lactide‐r‐glycolide) are synthesized by one‐pot ring‐opening polymerization of l‐lactide and glycolide in the presence of stannous octoate and 1‐dodecanol. Block copolymers, poly(l‐lactide‐b‐glycolide) are synthesized by ring‐opening polymerization of l‐lactide to generate poly(l‐lactide) first and then further ring‐opening polymerization of glycolide in the presence of poly(l‐lactide) and stannous octoate. The composition ratio of l‐lactide and glycolide is determined by the integration of the corresponding signals from 1H NMR spectra, which is consistent with the feeding ratio. Very few hetero‐sequences can be observed for block copolymers due to well‐defined microstructures. The block copolymers are more thermally stable than that of the random copolymers. The degree of crystallinity of the bock copolymers is relatively high compared to that of the random copolymers. The image of the block copolymers determined by field‐emission scanning electron microscopy (FESEM) shows partial aggregate domains containing spherical particles with an average diameter of around 200 nm, which is very different from that of the random copolymers. Block copolymers are more hydrophilic than that of the random copolymers due to the ordered structure and amphiphilic behavior of the block series.

Published: November 2022

AbstractAn efficient and environmentally‐friendly method for carbon‐centered radical cyclization of olefins via visible light photoredox catalysis to afford pyrrolo[3,2‐c]‐quinolines, oxindoles and quinoline‐2,4‐diones is described. This novel reaction successfully activated the α C−H bonds in one‐carbon units such as esters, chlorinated hydrocarbons and cyano compounds via HAT (hydrogen atom transfer) process by means of aryldiazonium salts. The transformation features good functional group tolerance, broad substrate scope, high atom economy, no need for transition metal or high temperature.

Published: November 2022

AbstractAfrican balsam (Daniella oliveri) leaves and cow dung are waste materials that are commonly accessible in Africa and can be used to produce biochar by simultaneous thermochemical processing. In this study, biochar was produced in a retort‐heated, non‐electrically powered, top‐lit updraft reactor using the biomass fuel‐powered thermochemical conversion of dried cow dung and African balsam leaves at an average temperature of 320 °C. The biochar was characterized using Fourier transform infrared spectroscopy (FTIR), energy dispersive spectroscopy (EDS), scanning electron microscopy (SEM), differential thermal analysis/thermogravimetric analysis (DTA/TGA), and Brunauer–Emmett–Teller (BET) analyses. After carbonization for 100 min, biochar was obtained from processed mixed leaves/cow dung with a yield of 70%. Fourier transform infrared analysis showed the presence of alkene, hydroxyl, alkyne, alkane, and sulfur‐containing functional groups. Scanning electron micrographs showed that the biochar's surface was made up of fibrillated particles with very few pores. The biochar was observed to have a surface area of 328.199 m2/g with a higher pore volume and lower pore size than biochar produced from cow dung alone. Energy dispersive spectroscopy showed that the biochar is mostly made up of carbon (67%), and that the introduction of the leaves into the biochar feedstock increased its carbon, silicon, potassium, and bromine content. Differential thermal analysis/thermogravimetric analyses revealed the biochar to be thermally stable. The findings of this study are helpful for attempts to manage solid wastes (African balsam leaves and cow dung), reduce environmental pollution, and produce biochar whose properties are adequate for it to be used as a soil additive. © 2022 Society of Chemical Industry and John Wiley & Sons, Ltd.

AbstractEpithelium‐specific ETS transcription factor 1 (ESE1) has been implicated in epithelial homeostasis, inflammation, as well as tumorigenesis, and cancer progression. However, numerous studies have reported contradictory roles—as an oncogene or a tumor suppressor of ESE1 in different cancers, and its function in the development and progression of pancreatic ductal adenocarcinoma (PDAC) has remained largely unexplored. Herein, we report that ESE1 was found upregulated in primary PDAC compared to normal pancreatic tissue, but high expression of ESE1 correlated to better relapse‐free survival in patients with PDAC. Interestingly, ESE1 was found to exhibit dual roles in regulation of malignant properties of PDAC cells in that its overexpression promoted cell proliferation, whereas its downregulation enhanced epithelial‐mesenchymal transition (EMT) phenotype. In the context of TGF‐β‐induced EMT, ESE1 is markedly downregulated at post‐transcriptional level, and reconstituted ESE1 expression partially reversed TGF‐β‐induced EMT marker expression. Furthermore, we identify AGR2 as a novel transcriptional target of ESE1 that participates in TGF‐β‐induced EMT in PDAC. Collectively, our findings reveal an ESE1/AGR2 axis that interacts with TGF‐β signaling to modulate EMT phenotype in PDAC.
Termviewer – A Web Application for Streamlined Human Phenotype Ontology (HPO) Tagging and Document Annotation

Published: November 2022

AbstractClinical notes from electronic health records (EHRs) contain a large amount of clinical phenotype data on patients that can provide insights into the phenotypic presentation of various diseases. A number of Natural Language Processing (NLP) algorithms have been utilized in the past few years to annotate medical concepts, such as Human Phenotype Ontology (HPO) terms, from clinical notes. However, efficient use of NLP algorithms requires the use of high‐quality clinical notes with phenotype descriptions, and erroneous annotations often exist in results from these NLP algorithms. Manual review by human experts is often needed to compile the correct phenotype information on individual patients. Here we develop TermViewer, a web application that allows multi‐party collaborative annotation and quality assessment of clinical notes that have already been processed and tagged by NLP algorithms. TermViewer allows users to view clinical notes with HPO terms highlighted, and to easily classify high‐quality notes and revise incorrect tagging of HPO terms. Currently, TermViewer combines MetaMap and cTAKES, two of the most widely used NLP tools for tagging medical terms, and identifies where these two tools agree and disagree, allowing users to perform collaborative manual reviews of computationally generated HPO annotations. TermViewer can be a stand‐alone tool for analyzing notes or become part of a machine‐learning pipeline where tagged HPO terms can be used as additional input data. TermViewer is available at https://github.com/WGLab/TermViewer.

Published: November 2022

AbstractBackground and ObjectivesThe eating quality of fresh instant rice differ significantly owing to its geographical origins. However, the method of geographical discrimination is still lacking. In this study, the determination of flavor profiles and multivariate statistical analysis have been applied for discriminating the geographical origins of 18 fresh instant rice from three provinces in Northeast China.FindingsThe principal component analysis (PCA) of electronic nose (E‐nose) data could rapidly distinguish the samples from three different provinces. The solid phase microextraction‐gas chromatograph‐mass spectrometer (SPME‐GC‐MS) results of samples from different provinces were clearly distinguished in PCA and hierarchical cluster analysis (HCA). The orthogonal partial least squares discriminant analysis (OPLS‐DA) model showed good discriminating ability (R2 = 0.894, Q2 = 0.845, and accuracy = 1.0). Nonanal, 2,4‐di‐tert‐butylphenol, 2,3‐dihydro‐benzofuran, 2‐pentylfuran, indole, pentadecane, 2‐pentadecanone, trans‐farnesol, isopropyl palmitate, and farnesyl acetone were identified as 10 marker compounds. Moreover, their good discrimination was verified in an additional nine samples.ConclusionsThe strategy of applying flavor profiles for discriminating the geographical origin of fresh instant rice has been proven to be an efficient and non‐destructive method.Significance and NoveltyOur study is helpful to control the quality of fresh instant rice and provides a methodological reference for the geographical discrimination of foods.
