Published: February 2020

AbstractEngineering interfacial properties of metal‐sulfides toward excellent electrochemical capability is imperative for advanced energy‐storage materials. However, they still suffer from an unclear mechanism of capacity fading, along with ineffective physical–chemical evolution. Herein, a highly‐effective Sb2S3 with double carbon is designed with interfacial SbC bonds and double carbon, which boosts promoting of ion transferring and alleviates the separation of both active phases (Sb, S). Through “voltage‐cutting” manners, the key elements of capacity improvement about phase transitions are further determined. As expected, even at 5.0 A g−1, the lithium‐storage capacity remains about 674 mAh g−1. Utilized as sodium ion battery (SIB) anode, the rate capacity still reaches up to 366 mAh g−1 at 3.0 A g−1, much larger than that of Sb2S3. Obtaining the full cell of Ni–Fe Prussian blue analog versus M‐Sb2S3@DC, the reversible capacity is 330 mAh g−1 at 0.5 A g−1. Supported by kinetic analysis, the excellent rate properties are determined by the surface‐controlling behaviors, mainly resulting from the decreased capacitive resistance and improved ion moving. Furthermore, the reassembling evolution of active phases is revealed in detail by ex situ techniques. This work is expected to offer significant insights into interfacial evolutions toward advanced energy‐storage systems.

AbstractThe rate‐determining process for electrochemical energy storage is largely determined by ion transport occurring in the electrode materials. Apart from decreasing the distance of ion diffusion, the enhancement of ionic mobility is crucial for ion transport. Here, a localized electron enhanced ion transport mechanism to promote ion mobility for ultrafast energy storage is proposed. Theoretical calculations and analysis reveal that highly localized electrons can be induced by intrinsic defects, and the migration barrier of ions can be obviously reduced. Consistently, experiment results reveal that this mechanism leads to an enhancement of Li/Na ion diffusivity by two orders of magnitude. At high mass loading of 10 mg cm−2 and high rate of 10C, a reversible energy storage capacity up to 190 mAh g−1 is achieved, which is ten times greater than achievable by commercial crystals with comparable dimensions.

AbstractParticle moving is a fundamental phenomenon of colloidal nanoparticles (NPs), but its influence on the interfacial interaction is far from been clarified. Herein, by mimicking the particle moving of upconverting fluoride NPs in a flowing cell, highly dependence of interfacial reactions on the particle moving of the colloidal NPs is clearly revealed by adopting combined in situ sum frequency generation and photoluminescence spectroscopies. It is found that particle moving can induce the rearrangement of the adsorbed interfacial water due to generating a more positively charged surface. More importantly, besides more prone to adsorb negatively charged carboxyl group of Rhodamine B via enhanced electrostatical interaction, particle moving at pH of 6.8 could reorient the xanthene ring of the dye parallel to the NP surface, via repelling the positively charged diethylamino groups. As a consequence, fluorescence resonance energy transfer efficiency from the upconverting NPs to Rhodamine B can be reversibly modulated by only tuning the flow. This work provides new insight into the interfacial interactions of the colloidal NPs, which are expected to guide their surface modification and practical applications.

Published: February 2020

AbstractConjugated polymers are of interest for next‐generation electronics due to their improved flexibility, low cost, and solution processability. However, a conjugated polymer is not a chemically “pure” material because the polymer chains are polydispersed in terms of molecular weights and/or chemical stereoregularities, leading to dispersions of both localized order and electronic properties. Taking advantage of these properties, a one‐step self‐refinement method is proposed to induce film‐depth‐resolved composition and aggregation gradient of conjugated‐polymer@insulator‐matrix for high‐performance organic field‐effect transistors and nonvolatile memories. During solvent evaporation, the higher ordered sub‐components of conjugated polymers are substantially enriched at the top surface of the blend film to form a morphologically continuous sublayer serving as high‐quality transport pathways to warrant high‐performance transistors. The less ordered sub‐components are distributed within insulator‐matrix in the bottom part of the film without connection with each other, which guarantees a reliable composite electret to help store sufficient immobilized charges to tune the operation of the device. Moreover, these conjugated‐polymer@insulator‐matrix films with insulator content as high as 95% show excellent optical transparency (>90%) and environmental stability (for months), which demonstrates great potential for use in transparent electronics.

AbstractHomozygosity for nonsense variants in CEP55 has been associated with a lethal condition characterized by multinucleated neurons, anhydramnios, renal dysplasia, cerebellar hypoplasia, and hydranencephaly (MARCH syndrome) also known as Meckel‐like syndrome. Missense variants in CEP55 have not previously been reported in association with disease. Here we describe seven living individuals from five families with biallelic CEP55 variants. Four unrelated individuals with microcephaly, speech delays, and bilateral toe syndactyly all have a common CEP55 variant c.70G>A p.(Glu24Lys) in trans with nonsense variants. Three siblings are homozygous for a consensus splice site variant near the end of the gene. These affected girls all have severely delayed development, microcephaly, and varying degrees of lissencephaly/pachygyria. Here we compare our seven patients with three previously reported families with a prenatal lethal phenotype (MARCH syndrome/Meckel‐like syndrome) due to homozygous CEP55 nonsense variants. Our series suggests that individuals with compound heterozygosity for nonsense and missense variants in CEP55 have a different viable phenotype. We show that homozygosity for a splice variant near the end of the CEP55 gene is also compatible with life.

AbstractWir untersuchen die Aktivierung von Kohlenstoffdioxid durch einfach geladene, hydratisierte Magnesium‐Kationen Mg .+(H2O)n mittels Infrarot‐Mehrfach‐Photonendissoziationsspektroskopie (IRMPD) und quantenchemischen Rechnungen. Die Spektren von [MgCO2(H2O)n].+ von 1250 bis 4000 cm−1 zeigen einen scharfen Übergang von n=2 auf n=3 für die Position der antisymmetrischen Streckschwingung des CO2‐Moleküls. Dies ist ein klarer Beleg für die Aktivierung des CO2‐Moleküls durch Ladungstransfer von Mg .+ auf CO2 für n≥3. In kleineren Clustern koordiniert lineares CO2 an die Metallzentren. Ab n=5 wird eine weitere Konformationsänderung beobachtet, wobei die Koordination von CO2.− an Mg2+ allmählich von zwei‐ zu einzähnig wechselt, konsistent mit der Präferenz des Mg2+‐Ions für Hexakoordination. Die Ergebnisse zeigen im Detail wie Hydratation die CO2‐Aktivierung durch Ladungstransfer an Metallzentren begünstigt.

Published: February 2020

AbstractWe analyze the X‐ray emission from the supernova remnant DEM L71 using the smoothed particle inference (SPI) technique. The high Fe abundance found appears to confirm the Type Ia origin. Our method allows the separation of the material ejected in the supernova explosion from the material swept up by the supernova shock wave. We are able to calculate the total mass of this swept‐up material to be about 228 ± 23 M⊙. We plot the posterior distribution for the number density parameter, and create a map of the density structure within the remnant. While the observed density shows substantial variations, we find our results are generally consistent with a two‐dimensional hydrodynamical model of the remnant that we have run. Assuming the ejected material arises from a Type Ia explosion, with no hydrogen present, we use the predicted yields from Type Ia models available in the literature to characterize the emitting gas. We find that the abundance of various elements match those predicted by deflagration‐to‐detonation transition (DDT) models. Our results, compatible with the Type Ia scenario, highlight the complexity of the remnant and the nature of the surrounding medium.

Published: February 2020

SummaryThis paper investigates a vital issue in wireless communication systems, which is the modulation classification. A proposed framework for modulation classification based on deep learning (DL) is presented in the presence of adjacent channel interference (ACI). This framework begins with the generation of constellation diagrams from the received data. These constellation diagrams are fed to convolutional neural networks (CNNs) for modulation classification. The objective of this process is to eliminate the manual feature extraction from the received data and make feature extraction process as a built‐in step with CNNs. Three types of CNNs are considered in this paper and compared for this objective. These types are AlexNet, VGG‐16, and VGG‐19. The proposed classifier is applied on Rayliegh and Rician fading channels.

Published: February 2020

ObjectiveThe transition from hospital to home is a period where older adults are at risk of experiencing depressive symptoms. The present study applied the Social Antecedent Model of Psychopathology (SAMP) to identify factors present at hospital discharge associated with depressive symptoms at discharge and future symptoms at 3‐ and 6‐month post‐discharge home.Method286 older adults aged over 65 (M = 78.38, SD = 7.68, 57% female) reported on a range of variables that were mapped to the SAMP at hospital discharge, 3‐ and 6‐month post‐discharge.ResultsAt baseline assessment, male gender, increased anxiety symptoms, low social support and low perceived coping ability were associated with concurrent baseline depressive symptoms. Depressive symptoms at baseline were strongly associated with future depressive symptoms at 3‐ and 6‐month post‐discharge. Low household physical activity was also associated with depressive symptoms at 3 months and elevated baseline anxiety symptoms and low social support were associated with depressive symptoms at 6‐month post‐discharge.ConclusionPre‐discharge screening of depressive and anxiety symptoms, social support, household physical activity and coping ability may assist in identifying elderly patients at risk of developing depressive symptoms during the hospital‐to‐home transition. These factors may also serve as potential targets for preventative interventions post‐discharge for older adults.

Published: February 2020

AbstractStructured illumination microscopy (SIM) is a well‐established method for optical sectioning and super‐resolution. The core of structured illumination is using a periodic pattern to excite image signals. This work reports a method for estimating minor pattern distortions from the raw image data and correcting these distortions during SIM image processing. The method was tested with both simulated and experimental image data from two‐photon Bessel light‐sheet SIM. The results proves the method is effective in challenging situations, where strong scattering background exists, signal‐to‐noise ratio (SNR) is low and the sample structure is sparse. Experimental results demonstrate restoring synaptic structures in deep brain tissue, despite the presence of strong light scattering and tissue‐induced SIM pattern distortion.

AbstractBreast cancer is a common malignant tumor suffered predominantly by women worldwide, which results in serious levels of morbidity and mortality. To control the effects of the cancer, it is critically important to elucidate the pathophysiological processes by which it occurs and develops. Reports have demonstrated that long noncoding RNAs perform a critical role in the development and metastasis of cancers. The lncRNA TTN‐AS1 is considered carcinogenic. Nevertheless, the importance and biological functions of TTN‐AS1 in breast cancer require greater exploration. In the current paper, we observed that TTN‐AS1 expression was significantly upregulated in breast cancer tissues/cells compared with those that are healthy. TTN‐AS1 enhanced the proliferation, migration, invasion, and epithelial‐mesenchymal transformation of breast cancer cells. Furthermore, a direct target of TTN‐AS1, miR‐139‐5p was negatively regulated. In addition, zinc finger E‐box binding homeobox 1 (ZEB1) is an important nuclear transcription factor, the expression of which is increased in multiple tumors. Here, we also found that ZEB1 is a target of miR‐139‐5p, of which TTN‐AS1 could regulate the expression through competition with miR‐139‐5p. That is, TTN‐AS1 promoted proliferation and invasion of breast cancer cells by interaction with the miR‐139‐5p/ZEB1 axis. In conclusion, the present study aimed to illustrate the significance of TTN‐AS1 in breast cancer metastasis and contribute to potentially innovative strategies for its treatment.
Computational screening of transition metal/p‐block hybrid electrocatalysts for CO2 reduction
Authors: Ananthaneni Sahithi , Rankin Rees B. 
Published: February 2020

AbstractAmong all the pollutants in the atmosphere, CO2 has the highest impact on global warming, and with the rising levels of this pollutant, studies on developing various technologies to convert CO2 into carbon‐neutral fuels and chemicals have become more valuable. In this work, we present a detailed computational study of electrochemical reduction of CO2 reaction (the CO2RR) to methane and/or methanol over different transition metal‐p block catalysts using density functional theory calculations. In addition to the catalyst structure, we studied reaction mechanisms using free energy diagrams that explain the product selectivity with respect to the competing hydrogen evolution reaction. Furthermore, we developed scaling relations between all the active C bound intermediate species with ΔG(CO*) and O bound species with ΔG(OH*) The limiting potential lines with ΔG(OH*) as the descriptor are much less negative compared to UL lines with ΔG(CO*) as the descriptor indicating that catalyst materials following pathways via OH− bound intermediate species require more negative potentials than CO*→ HCO* and CO2→ COOH* steps to convert into products. We developed thermodynamic volcano plots with two descriptors; the CO* and OH* binding free energies and determined the best catalyst material among the initially investigated catalyst materials expecting this plot will provide guidance to the future work on improving the activity of transition metal‐p block catalysts for this important reduction reaction.

AbstractBackgroundSpontaneous bacterial peritonitis (SBP) is one of the most critical complications of decompensated liver cirrhosis. This study aimed to assess whether ascitic neutrophil gelatinase‐associated lipocalin (NGAL), a reliable inflammation biomarker, can be used to detect SBP in decompensated cirrhosis patients and to predict mortality from decompensated cirrhosis‐related SBP.MethodsThis study included 204 hospitalized patients with ascites of decompensated liver cirrhosis and follow‐up of 28 days. We measured ascitic NGAL levels by the latex‐enhanced immunoturbidimetric method. Simultaneously, we observed the patterns of ascitic NGAL levels in the SBP group after 7 days of anti‐infection treatment with third‐generation cephalosporins.ResultsThe ascitic NGAL levels significantly increased in the SBP group compared with that in the non‐SBP group, 111(83.9, 178) ng/mL vs 48(35.4, 63) ng/mL, P < .001. Likewise, the ascitic NGAL levels of SBP were higher than non‐SBP with or without renal dysfunction. There was a positive relationship between ascitic NGAL and ascitic polymorphonuclear (PMN) leukocyte and a negative relationship between ascitic NGAL and ascitic albumin in the SBP group. An ascitic NGAL cutoff of 108.95 ng/mL was used for predicting a poor prognosis for SBP patients. Ascitic NGAL and the model for end‐stage liver disease score were independent risk factors in decompensated liver cirrhosis patients with SBP through multivariate Cox regression. A dynamic trend of ascitic NGAL in SBP patients was consistent with the clinical prognosis.ConclusionAscitic NGAL may not only be a biomarker for monitoring SBP but also a predictor for more severe outcomes in decompensated cirrhosis‐related SBP.

AbstractObjectiveTo investigate the correlation between hTREC and human papillomavirus (HPV) load and cervical intraepithelial neoplasia (CIN) grade II/III lesions and cervical cancer.MethodsA total of 135 patients with cervical lesions of different degrees admitted to our hospital from January 2016 to February 2017 were selected, including CIN I/III 65 cases, grade III 39 cases, and cervical cancer 31 cases. The expression of hTERC gene was detected by fluorescence in situ hybridization (FISH) in three groups, and the HPV load was detected by second‐generation hybridization capture (HC II) method, and its relationship with cervical lesion grade was analyzed. Department.ResultsThe positive expression rate of hTERC gene amplification was cervical cancer > CIN I/II lesion > CIN III lesion; the positive expression rate of HPV was cervical cancer > CIN I/II lesion > CIN III lesion. After treatment, the positive rate of hTERC gene amplification and HPV expression decreased significantly within 1 year (P < .05). Spearman's analysis showed that the degree of cervical lesion was positively correlated with hTREC and HPV load (P < .05).ConclusionhTREC and HPV are closely related to the occurrence and development of cervical precancerous lesions and cervical cancer. The abnormal amplification of hTERC gene increases with the grade of cervical lesions. Both of them can be used as auxiliary indicators for early screening, treatment, and prognosis of cervical cancer.
