AbstractOxygen reduction reaction (ORR) is Achilles’ heel of zinc‐air battery. The ideal electrocatalyst for ORR should combine both high activity and high stability. In order to achieve this goal, a new N, S co‐doped carbon coated Fe3N nanoparticles electrocatalyst with redistributed charge was designed and synthesized. The doping of S elements destroyed the ordered structure of carbon matrix, which cooperated with Fe3N nanoparticles to cause charge redistribution of carbon atoms. Furthermore, the carbon shell protected Fe3N from corrosion during the electrocatalytic process. Fe3N/NSC electrocatalyst showed excellent ORR property withE1/2=0.86 V, and the zinc‐air battery assembled based on it could run stably for more than 650 hours. This work provides a strategy to regulate the redistributed charge of carbon atoms to boost its electrocatalytic activity and stability together.
Full‐Color Emissive D‐D‐A Carbazole Luminophores: Red‐to‐NIR Mechano‐fluorochromism, Aggregation‐Induced Near‐Infrared Emission, and Application in Photodynamic Therapy

Published: December 2022

AbstractThe preparation of multifunctionalized luminophores with full‐color emission based on an identical core skeleton is a significative but challenging research topic. In this work, eight donor‐donor‐acceptor (D‐D‐A)‐type luminogens based on a central carbazole core bearing a C6hydrocarbon chain were designed by using different kinds of donor and acceptor units on the left and right, and synthesized in good yields. These D‐D‐A carbazole derivatives display deep‐blue, sky‐blue, cyan, green, yellow‐green, yellow, orange and red fluorescence in the solid state, achieving full‐color emission covering the whole visible light range under UV light illumination. Notably, the dicyano‐functionalized triphenylamine‐containing carbazole derivative exhibits rare aggregation‐induced near‐infrared emission and red‐to‐near‐infrared mechano‐fluorochromism with high contrast beyond 100 nm. Furthermore, the red‐emissive luminogen can serve as a potential candidate for cell imaging and photodynamic therapy (PDT). This work not only provides reference for the construction of full‐color emissive systems but also opens a new avenue to the preparation of multifunctionalized luminophores capable of simultaneous application in near‐Infrared mechanical‐force sensors and PDT fields.

Published: December 2022

AbstractMetal‐metal cooperativity is emerging as an important strategy in catalysis. This requires appropriate ligand scaffolds that can support two metals in close proximity. Here we report nickel‐promoted formation of a dinucleating planar macrocyclic ligand that can support bimetallic dinickel(II) and dinickel(I) complexes. Reaction outcomes can be tuned by variation of the substituents and reaction conditions to favour dinucleating macrocyclic, mononucleating macrocyclic or conventional pincer architectures.

AbstractAimAmong gynecological cancers, cervical cancer is the most common cause of cancer‐related death in developing countries. This study analyzes the incidence, mortality, and burden of cervical cancer using the Global Burden of Disease (GBD) 2019 study.Materials and MethodsThe GBD (2019) data on cervical cancer was extracted from the Global Health Data Exchange (GHDx) query tool. Age‐standardized rate (ASR) incidence, deaths, lost years of life (YLLs), years of life with disabilities (YLDs), and adjusted years of life with disabilities (DALYs) of cervical cancer in women were extracted. Data were extracted globally for 204 countries and groups based on a socio‐demographic index (SDI), World Health Organization (WHO) regions, continents, World Bank regions, and 22 GBD regions.ResultsThe higher standardized age incidence of cervical cancer is in lower SDI countries, Africa, the African region (According to the WHO), and Sub‐Saharan Africa (According to GBD regions). The highest deaths of ASR is in countries with low SDI, low‐income group, Africa, the African region (According to the World Health Organization), and Sub‐Saharan Africa (According to GBD regions). According to SDI classification, the highest DALYs ASR is in low SDI countries, World Bank Low‐income countries, African and then American continents, African region, Sub‐Saharan Africa, and then Latin America & Caribbean‐WB (Based on GBD regions).ConclusionIn 2019, incidence, mortality, and DALYs of cervical cancer mostly affected countries with lower socioeconomic status. Given that cervical cancer is highly preventable, access to screening services and the presence of trained and knowledgeable health care staff can reduce illness, suffering, and death caused by this malignancy. It is recommended to use the national and international potentials to reduce the incidence of this malignancy.

AbstractBackgroundMixed neuroendocrine carcinoma (NEC) and hepatocellular carcinoma (HCC) is extremely rare, thus radiological features have not been fully clarified.CaseA male patient (age: 70 years) visited our hospital due to a tumor in the liver. Examination using contrast‐enhanced computed tomography (CT) revealed a tumor (diameter: 5.0 cm) in hepatic segment 5, with early enhancement of the peripheral area and slight internal heterogeneous enhancement in the arterial and delayed phases, respectively. F‐18 fluorodeoxyglucose (FDG)‐positron emission tomography (PET)/CT revealed intratumoral heterogeneity, characterized by increased uptake (standardized uptake value, 12.10) in the corresponding low‐density area detected using enhanced CT relative to the surrounding areas of the tumor. On magnetic resonance imaging, diffusion‐weighted imaging also showed high intensity in the corresponding low‐density area detected using CT. Preoperatively, the patient was diagnosed with HCC and underwent anterior sectionectomy. Pathological findings revealed both HCC and NEC components, and the patient was diagnosed with mixed NEC and HCC. Comparison of component distribution with FDG‐PET/CT revealed an increased uptake area was congruent with the NEC component in the tumor.ConclusionIn this case, the difference in tumor components affected the uptake in FDG‐PET/CT. Such heterogeneous uptake with an enhanced spot may be useful for suspecting the presence of mixed NEC and HCC in patients with atypical HCC.
An intelligent signboard to assign the speed limit on ways using ANN

Published: December 2022

SummaryThis study incorporates artificial neural network (ANN) modeling to design an intelligent road signboard that uses internet of things (IoT) technology to assign the speed limit on interurban highways. The appropriate speed limit must be determined by traffic police experts based on weather conditions and times of the day. Here, an intelligent IoT‐based signboard is proposed to announce speed limits on roadways considering some effective parameters, such as temperature, humidity, time, and light. The signboard receives environmental data through its sensors and uses artificial neural networks to compute the speed limit. A feed‐forward neural network (FFNN) is provided as the most reliable model. A hybrid training method based on gray wolf optimization and Bayesian regularization is also developed to enhance model performance. The proposed hybrid model converges with an error of less than 3.0% to expert opinion. The model equations are extracted for use in a microcontroller that calculates a safe speed limit based on weather conditions. Additionally, the underlying IoT technology has enabled the police station to remotely monitor and control the developed system. Experimental results demonstrate the reliability of the designed signboard. In all experimental cases, the computed speed limits were in coincidence with the expert's estimations.

Published: December 2022

AbstractThe present study focuses on generating mesopores within H−ZSM‐5 (H−Z) zeolite via desilication and dealumination to incorporate Lewis acidic metal, such as Sn, into the framework (Sn4ZS180A15) to catalyse glucose isomerisation. Sn4ZS180A15 possesses enhanced surface area (457 m2 g−1), mesopore volume (0.585 cm3 g−1) and a high weak‐medium to strong acidic sites ratio, compared to parent H−Z (395 m2 g−1; 0.174 cm3 g−1). DRS‐UV‐Vis and XPS results corroborate Sn incorporation into the framework of Sn4ZS180A15, based on the absorbance peak around 200–220 nm and peaks appearing at 495.8 and 487.4 eV, respectively. Sn4ZS180A15 exhibits higher catalytic activity towards glucose isomerisation in ethanol−water at 110 °C, yielding 44.2 % fructose with 80.0 % selectivity. Conversely, the parent H−Z afforded negligible glucose conversion with a fructose yield of <1 % under identical conditions. Moreover, Sn‐incorporated on dealuminated (Sn4ZS0A15) and desilicated (Sn4ZS180A0) catalysts give a low yield of fructose (7–10 %), signifying the requirement of the desilication‐dealumination process before incorporating Sn into the framework.

Published: December 2022

AbstractThe molten phase of transition metal and lithium salts self‐assemble with non‐ionic surfactants to form lyotropic liquid crystalline (LLC) mesophases, which are important in the development of gel‐electrolytes and mesoporous materials. Here, we show that LiH2PO4 forms a semi‐stable LLC mesophase with 10‐lauryl ether (C12H25(OCH2CH2)10OH, C12E10), decoded as Li−EO−X (X is LiH2PO4/C12E10 mole ratio and between 2 and 200). The stability of the Li−EO−X phase is improved by increasing salt concentration (X>20) in the media. The semi‐stable Li−EO−X mesophase is further stabilized by adding either water by controlling the humidity or H3PO4 (PA) to the media. The phase behaviour of the above samples was investigated using POM, XRD, conductivity, and ATR‐FTIR measurements. The addition of PA not only brings stability and higher conductivity (increase from 0.1 to 8.9 mS/cm) to the mesophase but also produce an LLC gel‐electrolyte with a high buffer capacity that may be useful and important in various applications.

AbstractThe syntheses, structures, and circularly polarized luminescence (CPL) properties of bis(boron difluoride) complexes with chiral Schiff‐base ligands are described herein. A series of chiral Schiff‐base bis(boron difluoride) complexes based on the naphthalene backbone were prepared by reacting BF3⋅OEt2with the corresponding precursors, and the molecular structures were identified by NMR spectroscopy and X‐ray diffraction (XRD) analysis. These complexes exhibited efficient photoluminescence in dilute solution with high emission quantum yields (Φ) up to 0.99. The circularly polarized luminescence properties of the molecules were also investigated. Compared to solution, in the KBr dispersed pellet state the absolute value of the luminescence dissymmetry factor (glum) was significantly increased up to 1.2×10−2. The photophysical properties were further investigated by means of DFT calculations.

Published: December 2022

SummaryThe Internet of Things (IoT) is one of the paradigms related to the evolution of telecommunication networks which is contributing to the evolution of numerous use cases, such as smart city and smart agriculture. However, the current communication infrastructure and wireless communication technologies are not always able to guarantee a proper service for these IoT scenarios. Smart solutions are needed to overcome current terrestrial network limitations offering a cost‐effective way to extend the current terrestrial network coverage. For example, temporary extensions “on‐request” of the terrestrial infrastructure may be a viable solution to allow collecting data generated by nodes outside the current network coverage. Flying objects can help achieve this goal. Various studies supported the use of unmanned aerial vehicles (UAVs) as intermediate nodes between IoT devices and the network. However, such solutions have not been exhaustively tested yet in real‐case scenarios. This paper proposes an efficient solution to collect data from multiple IoT sensors in rural and remote areas based on UAVs. It describes the implementation of the proposed UAV‐based Long RangeWide Area Network (LoRaWAN) flying gateway able to collect data directly from LoRaWAN sensors during its flight, keep them stored in an onboard memory, and forward them at the end of its flying path to a platform where the authorized users can access them. A prototype of the gateway has been developed to assess the proposed solution through both indoor and outdoor tests aiming to test its feasibility both in terms of communication performance and UAV‐required hardware resources.
Exceptional preservation in Quaternary Atacama Desert Tufas: Evidence for increased groundwater and surface water in the Calama Basin, Atacama, Chile

Published: December 2022

AbstractExceptionally well‐preserved tufas located west of Calama, Atacama Desert, Chile, designated Santa Juana tufas, record episodic wetter conditions, relative to today, over the past 500,000 years. Globally, tufa architecture and depositional details are poorly understood as most described tufas have been degraded by weathering and erosion. In the hyperarid Atacama, post‐depositional alteration is negligible, therefore, the exceptional preservation of Santa Juana tufas documented in this study provides new information about tufa facies and their complex interactions. Santa Juana facies include microbial stromatolites, phytoherms, cascadestone, flowstone and porous limestone. Phytoherms, consisting of former plant stems coated with calcite, developed in channels, within pools, and along spring discharge aprons. Cascadestone, representing former waterfalls, preserves microbial filaments and delicate V‐shaped calcite crystals. Flowstone lines shallow subvertical to subhorizontal channels, representing sites of rapidly sluicing water flow. Porous limestone, containing sparse calcite and/or gypsum and anhydrite cement crystals, represents detrital accumulations. Stable isotope results, coupled with U/Th ages, show that by the Quaternary, relative to the Neogene, groundwater was less supercharged with volcanogenic CO2 so degassing was moderated. The δ18O ratios from Miocene–Pliocene palustrine and lacustrine freshwater carbonates that underlie Santa Juana tufas indicate significant evaporation, but the tufa δ18O signal indicates a less evaporative trend due to shorter atmosphere exposure time. Biological fractionation in δ13C is largely masked by the region's volcanogenic carbon footprint, although tufa petrography shows well‐preserved microbial filaments and laminations. The range of tufa ages in this study shows that there were wetter time periods within the drainage basin headwater area in the Quaternary, but that by the late Pleistocene to early Holocene, aridity to hyperaridity became established. The lack of diagenesis or alteration within the Santa Juana tufas indicates that there has been minimal rainfall since their deposition.
South American Dry Chaco rangelands: Positive effects of cattle trampling and transit on ecohydrological functioning

AbstractLivestock production in drylands requires consideration of the ecological applications of ecohydrological redistribution of water. Intensive cattle trampling and the associated increase of surface runoff are common concerns for rangeland productivity and sustainability. Here, we highlight a regional livestock production system in which cattle trails and trampling surrounding an artificial impoundment are purposely managed to enhance redistribution and availability of water for cattle drinking. Based on literature synthesis and field measurements, we first describe cattle production systems and surface water redistribution in the Dry Chaco rangelands of South America, and then develop a conceptual framework to synthesize the ecohydrological impacts of livestock production on these ecosystems. Critical to this framework is the pioshere—a degraded overgrazed and overtrampled area where vegetation has difficulties growing, usually close to the water points. The Dry Chaco rangelands have three key distinctive characteristics associated with the flat sedimentary environment lacking fresh groundwater and the very extensive ranching conditions: (1) cattle drinking water is provided by artificial impoundments filled by runoff, (2) heavy trampling around the impoundment and its adjacent areas generates a piosphere that favors runoff toward the impoundment, and (3) the impoundment, piosphere, and extensive forage areas are hydrologically connected with a network of cattle trails. We propose an ecohydrological framework where cattle transit and trampling alter the natural water circulation of these ecosystems, affecting small fractions of the landscape through increased runoff (compaction in piosphere and trails), surface connectivity (convergence of trails to piosphere to impoundment), and ponding (compaction of the impoundment floor) that operate together making water harvesting and storage possible. These effects have likely generated a positive water feedback on the expansion of livestock in the region with a relatively low impact on forage production. We highlight the role of livestock transit as a geomorphological agent capable of reshaping the hydrology of flat sedimentary rangelands in ways that can be managed positively for sustainable ranching systems. We suggest that the Dry Chaco offers an alternative paradigm for rangelands in which cattle trampling may contribute to sustainable seminatural production systems with implications for other dry and flat rangelands of the world.

Published: December 2022

AbstractAimsDiffusing capacity of the lung for carbon monoxide (DLCO) reduction is common in heart failure (HF) and is associated with a worse prognosis. Correlations between DLCO and pulmonary hypertension (PH) are unclear, and published data are conflicting; it has been shown that DLCO impairment may persist or even worsen after normalization of pulmonary pressures following left ventricle assist device (LVAD) implantation, maybe reflecting persistent pulmonary damage. We aimed to investigate the impact of pre‐implant DLCO and central haemodynamics on outcome in patients with advanced HF implanted with a LVAD.Methods and resultsWe retrospectively analysed pre‐implant and post‐implant data from 42 patients implanted with a LVAD at our institution.Out of 42 patients, 35 had post‐capillary PH before implantation, including 17 with combined post‐ and pre‐capillary PH (Cpc‐PH). Median DLCO was 59% (IQR 47–68%), and it inversely correlated with pulmonary vascular resistance (PVR) (P 0.037) and diastolic pulmonary gradient (DPG) (P 0.042).Compared with baseline, LVAD resulted in improvement in LV diameter (LVDd, P < 0.001), mitral regurgitation (P 0.022), and PH (mPAP 24 vs. 36 mmHg, P < 0.001; PAWP 12 vs. 23 mmHg, P 0.001; pulmonary artery compliance, CPA 3.1 vs. 1.9 mL/mmHg, P 0.021).Lower DLCO and Cpc‐PH at baseline were associated with a better LV reverse remodelling post‐implantation (P 0.027 for LVDd) but also with a smaller gain in CPA (P 0.049).ConclusionsBefore LVAD implantation, DLCO impairment is associated with higher PVR and DPG, suggesting that it might be an expression of persistent pulmonary damage occurring in Cpc‐PH.After LVAD implantation, both LV dimension and haemodynamics improve. Lower pre‐implant DLCO is associated with better LV reverse remodelling.
Playing to their strengths: Can focusing on typical in‐group strengths be detrimental to people of colour?
Authors: Debrosse Régine 
Published: December 2022

AbstractWith increasing awareness about racism, portrayals of communities of colour are shifting away from negative representations. Emphasizing their strengths could counter negative stereotypes about who they are and low expectations for who they can be, but could also backfire. In two experiments centring adolescents (n = 198) and adults of colour (n = 321), the effect of reflecting on a typical strength was moderated by perceived misalignments between racial/ethnic and ideal future selves (i.e., ethnic–ideal self‐discrepancy). For participants perceiving them as aligned, reflecting on a typical in‐group strength reduced actual–ideal self‐discrepancy. However, for participants perceiving them as misaligned, reflecting on a typical in‐group strength increased actual–ideal self‐discrepancy. Reflecting on a typical strength also indirectly influenced engagement, through actual–ideal self‐discrepancy. Reflecting on an atypical in‐group strength did not yield significant effects. Thus, emphasizing typical aspects of stigmatized communities, even when positive, sometimes impede identity and motivation.
