Enhancement of Sodium Ion Battery Performance Enabled by Oxygen Vacancies
Authors: Xu Yang , Zhou Min , Wang Xin , Wang Chengliang , Liang Liying , Grote Fabian , Wu Minghong , Mi Yan , Lei Yong
Published: June 2015

The utilization of oxygen vacancies (OVs) in sodium ion batteries (SIBs) is expected to enhance performance, but as yet it has rarely been reported. Taking the MoO3−x nanosheet anode as an example, for the first time we demonstrate the benefits of OVs on SIB performance. Moreover, the benefits at deep‐discharge conditions can be further promoted by an ultrathin Al2O3 coating. A series of measurements show that the OVs increase the electric conductivity and Na‐ion diffusion coefficient, and the promotion from ultrathin coating lies in the effective reduction of cycling‐induced solid‐electrolyte interphase. The coated nanosheets exhibited high reversible capacity and great rate capability with the capacities of 283.9 (50 mA g−1) and 179.3 mAh g−1 (1 A g−1) after 100 cycles. This work may not only arouse future attention on OVs for sodium energy storage, but also open up new possibilities for designing strategies to utilize defects in other energy storage systems.
Transparent, Ultrahigh‐Gas‐Barrier Films with a Brick–Mortar–Sand Structure
Authors: Dou Yibo , Pan Ting , Xu Simin , Yan Hong , Han Jingbin , Wei Min , Evans David G. , Duan Xue
Published: June 2015

Transparent and flexible gas‐barrier materials have shown broad applications in electronics, food, and pharmaceutical preservation. Herein, we report ultrahigh‐gas‐barrier films with a brick–mortar–sand structure fabricated by layer‐by‐layer (LBL) assembly of XAl‐layered double hydroxide (LDH, X=Mg, Ni, Zn, Co) nanoplatelets and polyacrylic acid (PAA) followed by CO2 infilling, denoted as (XAl‐LDH/PAA)n‐CO2. The near‐perfectly parallel orientation of the LDH “brick” creates a long diffusion length to hinder the transmission of gas molecules in the PAA “mortar”. Most significantly, both the experimental studies and theoretical simulations reveal that the chemically adsorbed CO2 acts like “sand” to fill the free volume at the organic–inorganic interface, which further depresses the diffusion of permeating gas. The strategy presented here provides a new insight into the perception of barrier mechanism, and the (XAl‐LDH/PAA)n‐CO2 film is among the best gas barrier films ever reported.

Published: June 2015

The ability to cross‐couple secondary alkyl centers is fraught with a number of problems, including difficult reductive elimination, which often leads to β‐hydride elimination. Whereas catalysts have been reported that provide decent selectivity for the expected (non‐rearranged) cross‐coupled product with aryl or heteroaryl oxidative‐addition partners, none have shown reliable selectivity with five‐membered‐ring heterocycles. In this report, a new, rationally designed catalyst, Pd‐PEPPSI‐IHeptCl, is demonstrated to be effective in selective cross‐coupling reactions with secondary alkyl reagents across an impressive variety of furans, thiophenes, and benzo‐fused derivatives (e.g., indoles, benzofurans), in most instances producing clean products with minimal, if any, migratory insertion for the first time.
Sequential Anion and Cation Exchange Reactions for Complete Material Transformations of Nanoparticles with Morphological Retention
Authors: Hodges James M. , Kletetschka Karel , Fenton Julie L. , Read Carlos G. , Schaak Raymond E.
Published: June 2015

Ion exchange reactions of colloidal nanocrystals provide access to complex products that are synthetically challenging using traditional hot‐injection methods. However, such reactions typically achieve only partial material transformations by employing either cation or anion exchange processes. It is now shown that anion and cation exchange reactions can be coupled together and applied sequentially in one integrated pathway that leads to complete material transformations of nanocrystal templates. Although the product nanocrystals do not contain any of the original constituent elements, the original morphology is retained, thereby fully decoupling morphology and composition control. The sequential anion/cation exchange process was applied to pseudo‐spherical CdO nanocrystals and ZnO tetrapods, producing fully transformed and shape‐controlled nanocrystals of copper and silver sulfides and selenides. Furthermore, hollow core–shell tetrapod ZnS@CdS heterostructures were readily accessible.
YAlC: A Bonding Chameleon with Heteropolyacetylene Features
Authors: Kotyrba Martin R. , Cuervo‐Reyes Eduardo , Nesper Reinhard
Published: June 2015

YAlC was prepared by a flux method. It crystallizes as a partially filled‐up TlI structure, showing remarkable structural aspects at the border between Zintl phases and intermetallics. This novel ternary aluminide–carbide exhibits a unique one‐dimensional multi‐center bond and a polyacetylene‐related aluminum carbide substructure. The different functionalities of aluminum and of yttrium are quite remarkable. While the latter behaves more like a trivalent ion, aluminum contributes considerably to covalent bonding with carbon. Still yttrium d states contribute, but hardly in a directed manner.

Authors: Paparo Albert , Silvia Jared S. , Kefalidis Christos E. , Spaniol Thomas P. , Maron Laurent , Okuda Jun , Cummins Christopher C.
Published: June 2015

We describe the stable and isolable dimetalloxycarbene [(TiX3)2(μ2‐CO2‐κ2C,O:κO′)] 5, where X=N‐(tert‐butyl)‐3,5‐dimethylanilide, which is stabilized by fluctuating μ2‐κ2C,O:κ1O′ coordination of the carbene carbon to both titanium centers of the dinuclear complex 5, as shown by variable‐temperature NMR studies. Quantum chemical calculations on the unmodified molecule indicated a higher energy of only +10.5 kJ mol−1 for the μ2‐κ1O:κ1O′ bonding mode of the free dimetalloxycarbene compared to the μ2‐κ2C,O:κ1O′ bonding mode of the masked dimetalloxycarbene. The parent cationic bridging formate complex [(TiX3)2(μ2‐OCHO‐κO:κO′)][B(C6F5)4], 4[B(C6F5)4], was simply deprotonated with the strong base K(N(SiMe3)2) to give 5. Complex 5 reacts smoothly with CO2 to generate the bridging oxalate complex [(TiX3)2(μ2‐C2O4‐κO:κO′′)], 6, in a CC bond formation reaction commonly anticipated for oxalate formation by reductive coupling of CO2 on low‐valent transition‐metal complexes.
CALCIUM‐INDUCED LIPID PEROXIDATION IS MEDIATED BY RHODNIUS HEME‐BINDING PROTEIN (RHBP) AND PREVENTED BY VITELLIN

Published: June 2015

Lipid peroxidation is promoted by the quasi‐lipoxygenase (QL) activity of heme proteins and enhanced by the presence of free calcium. Unlike mammalian plasma, the hemolymph of Rhodnius prolixus, a vector of Chagas disease, contains both a free heme‐binding protein (RHBP) and circulating lipoproteins. RHBP binds and prevents the heme groups of the proteins from participating in lipid peroxidation reactions. Herein, we show that despite being bound to RHBP, heme groups promote lipid peroxidation through a calcium‐dependent QL reaction. This reaction is readily inhibited by the presence of ethylene glycol tetraacetic acid (EGTA), the antioxidant butylated hydroxytoluene or micromolar levels of the main yolk phosphoprotein vitellin (Vt). The inhibition of lipid peroxidation is eliminated by the in vitro dephosphorylation of Vt, indicating that this reaction depends on the interaction of free calcium ions with negatively charged phosphoamino acids. Our results demonstrate that calcium chelation mediated by phosphoproteins occurs via an antioxidant mechanism that protects living organisms from lipid peroxidation.
Superior Disembedding Performance in Childhood Predicts Adolescent Severity of Repetitive Behaviors: A Seven Years Follow‐Up of Individuals With Autism Spectrum Disorder
Authors: Eussen Mart L. J. M. , Gool Arthur R. Van , Louwerse Anneke , Verhulst Frank C. , Greaves‐Lord Kirstin
Published: June 2015

Previous research suggests that individuals with autism spectrum disorder (ASD) show a detail‐focused cognitive style. The aim of the current longitudinal study was to investigate whether this detail‐focused cognitive style in childhood predicted a higher symptom severity of repetitive and restrictive behaviors and interests (RRBI) in adolescence. The Childhood Embedded Figures Test (CEFT) and the Autism Diagnostic Observation Schedule (ADOS) were administered in 87 children with ASD at the age of 6–12 years old (T1), and the ADOS was readministered 7 years later when the participants were 12–19 years old (T2). Linear regression analyses were performed to investigate whether accuracy and reaction time in the complex versus simple CEFT condition and performance in the complex condition predicted T2 ADOS RRBI calibrated severity scores (CSS), while taking into consideration relevant covariates and ADOS RRBI CSS at T1. The CEFT performance (accuracy in the complex condition divided by the time needed) significantly predicted higher ADOS RRBI CSS at T2 (ΔR2 = 15%). This finding further supports the detail‐focused cognitive style in individuals with ASD, and shows that it is also predictive of future RRBI symptoms over time.

The loss of scents: Do defects in olfactory sensory neuron development underlie human disease?
Authors: Whitlock Kathleen E.
Published: June 2015

The olfactory system is a fascinating and beguiling sensory system: olfactory sensory neurons detect odors underlying behaviors essential for mate choice, food selection, and escape from predators, among others. These sensory neurons are unique in that they have dendrites contacting the outside world, yet their first synapse lies in the central nervous system. The information entering the central nervous system is used to create odor memories that play a profound role in recognition of individuals, places, and appropriate foods. Here, the structure of the olfactory epithelium is given as an overview to discuss the origin of the olfactory placode, the plasticity of the olfactory sensory neurons, and finally the origins of the gonadotropin‐releasing hormone neuroendocrine cells. For the purposes of this review, the development of the peripheral sensory system will be analyzed, incorporating recently published studies highlighting the potential novelties in development mechanisms. Specifically, an emerging model where the olfactory epithelium and olfactory bulb develop simultaneously from a continuous neurectoderm patterned at the end of gastrulation, and the multiple origins of the gonadotropin‐releasing hormone neuroendocrine cells associated with the olfactory sensory system development will be presented. Advances in the understanding of the basic mechanisms underlying olfactory sensory system development allows for a more thorough understanding of the potential causes of human disease.

Luminescent sensing and imaging of oxygen: Fierce competition to the Clark electrode
Authors: Wolfbeis Otto S.
Published: June 2015

Luminescence‐based sensing schemes for oxygen have experienced a fast growth and are in the process of replacing the Clark electrode in many fields. Unlike electrodes, sensing is not limited to point measurements via fiber optic microsensors, but includes additional features such as planar sensing, imaging, and intracellular assays using nanosized sensor particles. In this essay, I review and discuss the essentials of (i) common solid‐state sensor approaches based on the use of luminescent indicator dyes and host polymers; (ii) fiber optic and planar sensing schemes; (iii) nanoparticle‐based intracellular sensing; and (iv) common spectroscopies. Optical sensors are also capable of multiple simultaneous sensing (such as O2 and temperature). Sensors for O2 are produced nowadays in large quantities in industry. Fields of application include sensing of O2 in plant and animal physiology, in clinical chemistry, in marine sciences, in the chemical industry and in process biotechnology.
Tissue distribution study of columbianadin and its active metabolite columbianetin in rats
Authors: Zhang You‐Bo , Yang Xiu‐Wei
Published: June 2015

Columbianadin, one of the main bioactive constituents of the roots of Angelica pubescens Maxim. f. biserrata Shan et Yuan, has been found to possess obvious pharmacological effects in previous studies. In this study, a valid and sensitive reverse‐phase high‐performance liquid chromatography (RP‐HPLC) method was established and validated for the determination of columbianadin (CBN) and its active metabolite columbianetin (CBT) in rat tissue samples. Sample separation was performed on an RP‐HPLC column using a mobile phase of MeOH–H2O (75:25, v/v) at a flow rate of 1.0 mL/min. The UV absorbance of the samples was measured at the wavelength 325 nm. The calibration curves for CBN were linear over the ranges of 0.5–20 µg/g for brain, testes and muscle, 1.0–10.0 µg/g for stomach and intestine, and 0.2–20.0 µg/g for heart, liver, spleen, lung and kidney. The calibration curves for CBT were linear over the ranges of 0.5–25 µg/g for stomach and intestine, and 0.1–10.0 µg/g for heart, liver, spleen, lung and kidney. The analysis method was successfully applied to a tissue distribution study of CBN and CBT after intravenous administration of CBN to rats. The results of this study indicated that CBN could be detected in all of the selected tissues after i.v. administration. CBN was distributed to rat tissues rapidly and could be metabolized to CBT in most detected tissues. Of the detected tissues, heart had the highest uptake of CBN, which suggested that heart might be one of the main target tissues of CBN. Concentrations of CBT were obviously higher in the digestive system than in other assayed tissues. The information provided by this research is very useful for gaining knowledge of the capacities of CBN and CBT to access different tissues. Copyright © 2015 John Wiley & Sons, Ltd.
Coping strategies in a sample of anxiety patients: factorial analysis and associations with psychopathology
Authors: Pozzi Gino , Frustaci Alessandra , Tedeschi Daniela , Solaroli Silvia , Grandinetti Paolo , Di Nicola Marco , Janiri Luigi
Published: June 2015

Background

The relationship between coping styles and mental disorders has received considerable attention and instruments have been developed to assess coping strategies. The measurement by means of category systems has been criticized and a functional hierarchy of action types linked to the adaptive processes is preferred. We aimed to determine which factors may exist within the Brief‐COPE (Brief Coping Orientation to Problems Experienced – COPE – Inventory) in an Italian sample of patients with anxiety disorders; and if these factors correlate with the severity of psychopathology or with other characteristics.

Methods

A total sample of 148 patients was recruited. The Brief‐COPE inventory, the Symptom Check List 90‐Revised, the Penn State Worry Questionnaire, the Zung Anxiety Status Inventory and the Zung Self‐Rating Anxiety Scale were administered.

Results

Factor analysis of the Brief‐COPE yielded nine factors accounting for 65.48% of the variance. Patients scored higher on Searching Support, followed by Acceptance, Changing Perspective, and Problem Solving. Associations between measures of psychopathology and factors of coping strategies, mostly Searching support and Avoidance, were found.

Conclusions

Data of the present study support a nine‐factor structure of the Brief‐COPE that includes five broad dimensions of coping. Psychopathology was mostly related to Searching support and Avoidance factors, showing that these strategies may reflect ineffective ways of coping; Problem solving and Changing perspective could be a valid approach to moderate anxiety/depression symptoms and psychopathology in general.
Discrepancy of target sites between clinician and cytopathological reports in head neck fine needle aspiration: Did I miss the target or did the clinician mistake the organ site?

Published: June 2015

The diagnostic accuracy of fine needle aspiration cytology (FNAC) of head and neck lesions is relatively high, but cytologic interpretation might be confusing if the sample is lacking typical cytologic features according to labeled site by physician. These errors may have an impact on pathology search engines, healthcare costs or even adverse outcomes. The cytology archive database of multiple institutions in southern Iran and Australia covering the period 2001–2011, were searched using keywords: salivary gland, head, neck, FNAC, and cytology. All the extracted reports were reviewed. The reports which showed discordance between the clinician's impression of the organ involved and subsequent fine needle biopsy request, and the eventual cytological diagnosis were selected. The cytological diagnosis was confirmed by histology or cell block, with assistance from imaging, clinical outcome, physical examination, molecular studies, or microbiological culture. The total number of 10,200 head and neck superficial FNAC were included in the study, from which 48 cases showed discordance between the clinicians request and the actual site of pathology. Apart from the histopathology, the imaging, clinical history, physical examination, immunohistochemical study, microbiologic culture and molecular testing helped to finalize the target organ of pathology in 23, 6, 7, 8, 2, and 1 cases respectively. The commonest discrepancies were for FNAC of “salivary gland” [total: 20 with actual final pathology in: bone (7), soft tissue (5), lymph node (3), odontogenic (3) and skin (2)], “lymph node” [total: 12 with final pathology in: soft tissue (3), skin (3), bone (1) and brain (1)], “soft tissue” [total: 11 with final pathology in: bone (5), skin (2), salivary gland (1), and ocular region (1)] and “skin” [total: 5 with final pathology in: lymph node (2), bone (1), soft tissue (1) and salivary gland (1)]. The primary physician requesting FNAC of head and neck lesions are incorrect in their clinical impression of the actual site in nearly 0.5 percent of cases, due to the overlapping clinical and imaging findings or possibly due to inadequate history taking or physical examination.

Published: June 2015

Taking advantage of an improved synthesis of [Ti(η6‐C6H6)2], we report here the first examples of ansa‐bridged bis(benzene) titanium complexes. Deprotonation of [Ti(η6‐C6H6)2] with nBuLi in the presence of N,N,N′,N′′,N′′‐pentamethyldiethylenetriamine (pmdta) leads to the corresponding 1,1′‐dilithio salt [Ti(η6‐C6H5Li)2]⋅pmdta that enables the preparation of the first one‐ and two‐atom‐bridged complexes by simple salt metathesis. The ansa complexes were fully characterized (NMR spectroscopy, UV/Vis spectroscopy, elemental analysis, and X‐ray crystallography) and further studied electrochemically and computationally. Moreover, [Ti(η6‐C6H6)2] is found to react with the Lewis base 1,3‐dimethylimidazole‐2‐ylidene (IMe) to give the bent sandwich complex [Ti(η6‐C6H6)2(IMe)].
Rapid Asymmetric Transfer Hydroformylation (ATHF) of Disubstituted Alkenes Using Paraformaldehyde as a Syngas Surrogate
Authors: Fuentes José A. , Pittaway Rachael , Clarke Matthew L.
Published: June 2015

As an alternative to conventional asymmetric hydroformylation (AHF), asymmetric transfer hydroformylation (ATHF) by using formaldehyde as a surrogate for syngas is reported. A catalyst derived from commercially available [Rh(acac)(CO)2] (acac=acetylacetonate) and 1,2‐bis[(2S,5S)‐2,5‐diphenylphospholano]ethane(1,5‐cyclooctadiene) (Ph‐BPE) stands out in terms of both activity and enantioselectivity. Remarkably, not only are high selectivities achievable, the reactions are very simple to perform, and higher enantioselectivity (up to 96 % ee) and/or turnover frequencies than those achievable by using the same catalyst (or other leading catalysts) can be obtained by using typical conditions for AHF.
