AbstractOptical nanoantennas are of great importance for photonic devices and spectroscopy due to their capability of squeezing light at the nanoscale and enhancing light–matter interactions. Among them, nanoantennas made of polar crystals supporting phonon polaritons (phononic nanoantennas) exhibit the highest quality factors. This is due to the low optical losses inherent in these materials, which, however, hinder the spectral tuning of the nanoantennas due to their dielectric nature. Here, active and passive tuning of ultranarrow resonances in phononic nanoantennas is realized over a wide spectral range (≈35 cm−1, being the resonance linewidth ≈9 cm−1), monitored by near‐field nanoscopy. To do that, the local environment of a single nanoantenna made of hexagonal boron nitride is modified by placing it on different polar substrates, such as quartz and 4H‐silicon carbide, or covering it with layers of a high‐refractive‐index van der Waals crystal (WSe2). Importantly, active tuning of the nanoantenna polaritonic resonances is demonstrated by placing it on top of a gated graphene monolayer in which the Fermi energy is varied. This work presents the realization of tunable polaritonic nanoantennas with ultranarrow resonances, which can find applications in active nanooptics and (bio)sensing.

AbstractRadiotherapy, a mainstay of first‐line cancer treatment, suffers from its high‐dose radiation‐induced systemic toxicity and radioresistance caused by the immunosuppressive tumor microenvironment. The synergy between radiosensitization and immunomodulation may overcome these obstacles for advanced radiotherapy. Here, the authors propose a radiosensitization cooperated with stimulator of interferon genes (STING) pathway activation strategy by fabricating a novel lanthanide‐doped radiosensitizer‐based metal‐phenolic network, NaGdF4:Nd@NaLuF4@PEG‐polyphenol/Mn (DSPM). The amphiphilic PEG‐polyphenol successfully coordinates with NaGdF4:Nd@NaLuF4 (radiosensitizer) and Mn2+ via robust metal‐phenolic coordination. After cell internalization, the pH‐responsive disassembly of DSPM triggers the release of their payloads, wherein radiosensitizer sensitizes cancer cells to X‐ray and Mn2+ promote STING pathway activation. This radiosensitizer‐based DSPM remarkably benefits dendritic cell maturation, anticancer therapeutics in primary tumors, accompanied by robust systemic immune therapeutic performance against metastatic tumors. Therefore, a powerful radiosensitization with STING pathway activation mediated immunostimulation strategy is highlighted here to optimize cancer radiotherapy.

AbstractFlexible electrodes with excellent energy storage and conversion properties that can be produced by a simple process are highly desirable for supercapacitors. Herein, Cobalt‐Nickel double hydroxide (CoNi‐DH) micro‐nanosheet arrays are prepared uniformly on naturally sedimented Ti3C2Tx films by an etching‐deposition‐growth process to form a CoNi‐DH@Ti3C2Tx heterostructure. The naturally sedimented Ti3C2Tx film serves as the substrate to minimize aggregation of the CoNi‐DH nanoarrays to enhance the electrical conductivity. Furthermore, the hierarchical structure comprised of the CoNi‐DH interconnected nanoarrays promotes electrolyte access. By taking advantage of the excellent electrical conduction and high theoretical specific capacitance, the flexible CoNi‐DH@Ti3C2Tx electrode in the supercapacitor delivers a superior specific capacitance of 919.5 F g−1 at 1 A g−1, and remarkable capacitance retention of 89.6% after 5000 cycles at 20 A g−1. Density‐functional theory calculations are performed to investigate the charge density difference and partial density of states of CoNi‐DH@Ti3C2Tx and the theoretical assessment suggests that the chemical bonds between Ti3C2Tx and CoNi‐DH are critical to the charge transport, electrical conductivity, and structural stability.

Abstract2D materials are increasingly being investigated for their nonvolatile switching properties as a step toward downscaling of core electronic elements. Here, the interplay between electrochemically active silver (Ag) cations and layered indium selenide (InSe), a 2D metal monochalcogenide, is investigated to demonstrate a nonvolatile switching device. Detailed microscopic characterization supported with density functional theory calculations reveals cationic filamentary‐based nonvolatile switching mechanism of γ‐InSe in a crossplanar architecture. This is electrically driven by diffusion of Ag ions through the layered InSe stack. The InSe‐based memory cells exhibit a switching ratio of ≈103 and a memory retention of >105 s. This work opens new opportunities to enhance resistive switching performances of 2D materials for next‐generation information storage and brain inspired computation using active metal diffusion.

AbstractLithium/fluorinated graphite (Li/CFx) primary batteries show great promise for applications in a wide range of energy storage systems due to their high energy density (>2100 Wh kg–1) and low self‐discharge rate (<0.5% per year at 25 °C). While the electrochemical performance of the CFx cathode is indeed promising, the discharge reaction mechanism is not thoroughly understood to date. In this article, a multiscale investigation of the CFx discharge mechanism is performed using a novel cathode structure to minimize the carbon and fluorine additives for precise cathode characterizations. Titration gas chromatography, X‐ray diffraction, Raman spectroscopy, X‐ray photoelectron spectroscopy, scanning electron microscopy, cross‐sectional focused ion beam, high‐resolution transmission electron microscopy, and scanning transmission electron microscopy with electron energy loss spectroscopy are utilized to investigate this system. Results show no metallic lithium deposition or intercalation during the discharge reaction. Crystalline lithium fluoride particles uniformly distributed with <10 nm sizes into the CFx layers, and carbon with lower sp2 content similar to the hard‐carbon structure are the products during discharge. This work deepens the understanding of CFx as a high energy density cathode material and highlights the need for future investigations on primary battery materials to advance performance.

ObjectiveTranscranial ultrasound stimulation (TUS) is a promising noninvasive brain stimulation technique with advantages of high spatial precision and ability to target deep brain regions. This study aimed to develop a TUS protocol to effectively induce brain plasticity in human subjects.MethodsAn 80‐second train of theta burst patterned TUS (tbTUS), regularly patterned TUS (rTUS) with the same sonication duration, and sham tbTUS was delivered to the motor cortex in healthy subjects. Transcranial magnetic stimulation (TMS) was used to examine changes in corticospinal excitability, intracortical inhibition and facilitation, and the site of plasticity induction. The effects of motor cortical tbTUS on a visuomotor task and the effects of occipital cortex tbTUS on motor cortical excitability were also tested.ResultsThe tbTUS produced consistent increase in corticospinal excitability for at least 30 minutes, whereas rTUS and sham tbTUS produced no significant change. tbTUS decreased short‐interval intracortical inhibition and increased intracortical facilitation. The effects of TMS in different current directions suggested that the site of the plastic changes was within the motor cortex. tbTUS to the occipital cortex did not change motor cortical excitability. Motor cortical tbTUS shortened movement time in a visuomotor task.InterpretationtbTUS is a novel and efficient paradigm to induce cortical plasticity in humans. It has the potential to be developed for neuromodulation treatment for neurological and psychiatric disorders, and to advance neuroscience research. ANN NEUROL 2022;91:238–252

AbstractNon‐invasive dynamic tracking of lysosomes and their interactions with other organelles is important for the study of lysosomal function and related diseases. However, many fluorescent dyes developed so far to target lysosomes cannot be used to monitor these processes due to the high concentrations required for imaging, long cell penetration times, and non‐ideal photostability. In this regard, we synthesized three lysosomal targeting probes with large Stokes shifts, good stability, and high brightness. The Q‐P‐ARh dye, developed by us for the first time, can stain lysosomes at ultra‐low concentrations (1.0 nM) without affecting the physiological functions of the lysosomes. More importantly, its excellent anti‐interference ability and ultrafast lysosomal staining ability (within 1.0 min) clearly monitored the entire dynamic process of lipophagy. Ultimately, this method can greatly contribute to the study of autophagy pathways. This novel fluorescence platform shows great promise for the development of biological probes for application in pathological environments.

Published: December 2021

AbstractIn high‐frequency devices and thermal management areas, there is an urgent demand for polyamide with high‐mechanical strength and high‐thermal conductivity simultaneously. In this study, semiaromatic polyamide 10T/nanodiamond (ND) nanocomposites were prepared via predispersion and in situ polymerization, which was conducive to achieve the homogeneous distribution of ND in the PA10T matrix. The tensile strength and impact strength of the PA10T/1.0 wt% ND nanocomposite increased by 27% and 102%, respectively. With the content of only 1.0 wt% of ND, the thermal conductivity of the nanocomposite increased from 0.36 to 0.51 W/(m·K). In addition, the thermomechanical properties and thermal stability of nanocomposites were also been improved. We attributed the composite reinforcing effect to not only the uniform dispersion of ND in the matrix and strong interfacial interactions between ND and PA10T molecules, but also the formation of ND‐centered cross‐linking structures in the composites. Thus, ND compositing is a promising way to enhance both the mechanical properties and thermal conductivity of polyamide.
Comparing centralized and point‐of‐use treatments of per‐ and polyfluoroalkyl substances

Published: December 2021

AbstractPer‐ and polyfluoroalkyl substances (PFAS) chemicals are a growing threat to public health and safety. This study seeks to compare the life cycle environmental, economic, and human health performances of centralized and point‐of‐use (POU) systems used to upgrade existing drinking water treatment facilities for enhanced PFAS removal, using Merrimack, NH as a testbed. Out of all studied system upgrade scenarios, a POU scenario that combines granular activated carbon and ion exchange filters has the lowest environmental and human health impacts and relatively low economic impact. Despite all drinking water taps in the house being protected, the centralized scenario does not perform the best in terms of the health impacts because of its relatively low perfluorooctane sulfonate removal efficiency. This suggests a potential tradeoff between protecting the highest number of taps and achieving the highest removal efficiency at limited taps as two water treatment objectives.

Published: December 2021

AbstractIn this study, multiwalled carbon nanotubes (MWCNTs) were used as a property improvers for fuel obtained from Nannochloropsis oculate for application in a compression ignition engine. The engine's performance was monitored in accordance with its newly induced characteristics. The fixed biodiesel ratio was blended with different proportions of MWCNTs. The nanotubes were ultrasonicated with the biodiesel in different doses of 50,75, 100 and 150 ppm, respectively, and the resulting fuels were subjected to performance tests as compared with conventional diesel‐fuel in a Yanmar Model‐TF120M diesel engine. It was observed that cylinder pressure and heat release rates were higher under full load condition as compared with those obtained for the diesel fuel. Furthermore, the results compared favorably for both fuels in terms of combustion, emissions and engine performance. The brake thermal efficiency of the blended fuel improved by 2.72, 2.81, 3.07 and 2.24% for BC‐50, BC‐75, BC‐100 and BC‐150 as compared with that of diesel fuel. The release of CO2, NO
x
, hydrocarbons and carbon monoxide decreased in favor of the blends. From the analysis, a dosing level of 100 ppm MWCNTs in the biofuel is recommended for best engine performance and combustion, with optimal emission reduction. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd
Large‐scale biomass storage for electricity generation: a comprehensive field‐test campaign in southern Spain

Published: December 2021

AbstractBiomass is a renewable energy source that, due to its strong seasonality, needs to be stored, handled, and managed under suitable conditions for its optimal use. Storage is therefore a key process in which biomass can lose many of its qualities as a fuel, but which can also serve to improve the condition of the resource. This paper presents results from a study to assess the effect of large‐scale storage on a range of different biomass resources that was carried out at an electricity generation plant located in southern Spain. It included a series of field tests carried out with different types of biomass resources, to observe the behavior of these products during storage and the changes in their main characteristics. Based on these results, recommendations have been proposed for the optimal storage management of each of the products. The testing program confirms that the initial moisture content of the biomass, particle size, and the leafy content are critical aspects to consider to avoid self‐ignition and dry matter losses. Biomass with high moisture content should therefore be stored in small stockpiles and should be consumed immediately. This is especially important in the case of olive leaves and pine prunings when they have a high initial moisture content. Stockpiles of drier biomass, such as dried olive pomace, fruit tree pruning or dried olive pruning can reach up to 1200 t and be stored for up to 6 months, under adequately controlled conditions. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd

Published: December 2021

AbstractTwo nor‐diterpenes, 9,11‐dihydrogracilin A (1) and the previously unreported 9,11‐dihydrogracillinone A (2), were isolated from the sponge Dendrilla antarctica. The sponge was collected by trawling at a depth of 49 m, from the research vessel Puerto Deseado, near the coast of Tierra del Fuego, farther north than the reported habitat for this species. Since these compounds were particularly abundant and the sponge was free from epibionts, both 1 and 2 were included in soluble‐matrix paints and tested for antifouling activity in the ocean. The results obtained from these experiments clearly indicated a potent antifouling activity for both compounds against a variety of colonizing organisms, and established a probable role as natural antifoulants for these abundant secondary metabolites and other structurally related compounds previously isolated from Dendrilla spp.

Published: December 2021

AbstractCarduus nutans L. (Compositae) has been extensively used for medicinal purposes. As other representatives of the genus it is implemented in the treatment of liver disorders and used as diuretic and digestive agent. Previous studies have determined the predominant classes of secondary metabolites in Carduus species. Among the major representatives of their extracts flavonoids, phenolic acids, coumarins, sterols and terpenes were identified. The antiradical capacity of three extracts assessed in the DPPH test revealed the highest radical scavenging properties of methanol extract (the EC50 618±10.03 μg/mL) and based on these results it was selected for phenolic content determination. (TPC=61.49 mg/g). To understand better the induced pharmacological effects of the plant the aim of the study was to determine the composition of the methanol extract from the inflorescences of C. nutans and to study their phenolic composition. In order to determine the composition in a more efficient way, the crude extract was fractionated and subjected to hydrolyses. As a result more than twenty phenolic acids and flavonoids were identified in the extract and fractions by HPLC‐DAD and/or HPLC‐ESI‐TOF‐MS. The total extract was later subjected to fractionation by centrifugal partition chromatography using the Arizona system composed of hexane/ethyl acetate/methanol/water (0.7 : 4 : 0.8 : 4 v/v/v/v) to produce fractions enriched in flavonoids that are of high pharmacological significance.

Authors: Shao Jing , Li Wenchao , Aneye Cedric , Fang Wei 
Published: December 2021

AbstractMany studies explored consumer motivation toward purchasing behavior of environmentally friendly products. However, although consumers are aware of products' possible environmental and social impacts, there is no transparent approach to obtain such information and facilitate their green purchasing accordingly. Therefore, based on the developed novel scale of sustainability‐related information of the product as a moderating factor, this research aims to study the facilitating mechanism of such information in influencing consumers' purchasing behavior with a premium price. An online survey of 713 consumers was conducted in the context of purchasing new energy vehicles. Using SPSS 25, the social impact information could significantly affect the premium price the consumers would pay compared to environmental impact information. Furthermore, marital status, income level, and age significantly affect the purchasing behavior of potential consumers. This study provides theoretical and methodological support for enterprises to develop product sustainability indicators and guide them in designing business activities.

AbstractColorectal cancer (CRC) is one of the most common malignant tumours, with multiple driving factors and biological transitions involved in its development. Claudin‐2 (CLDN2), a well‐defined component of cellular tight junction, has been indicated to associate with CRC progression. However, the function of CLDN2 and the underlying mechanism whereby the downstream signalling transduction is regulated in CRC remains largely unclear. In this study, we demonstrated that CLDN2 is upregulated in CRC samples and associated with poor survival. And CLDN2 depletion significantly promotes N‐myc downstream‐regulated gene 1 (NDRG1) transcription, leading to termination of the CRC growth and metastasis in vitro and in vivo. Mechanistically, this process promotes CLDN2/ZO1/ZONAB complex dissociation and ZONAB shuttle into nucleus to enrich in the promoter of NDRG1. Thus, this study reveals a novel CLDN2/ZO1/ZONAB‐NDRG1 axis in CRC by regulating the expression of EMT‐related genes and CDKIs, suggesting CLDN2 may serve as a promising target for CRC treatment.
