Published: September 2018

AbstractMetallic lithium (Li) is a promising anode for next‐generation high‐energy‐density batteries, but its applications are still hampered due to the limited charging/discharging rate and poor cycling performance. Here, a hierarchical 3D porous architecture is designed with a binary network of continuous silver nanowires assembled on an interconnected 3D graphene skeleton as the host for Li‐metal composite anodes, which offers a significant boost in both charging/discharging rates and long‐term cycling performance for Li‐metal batteries. This unique hierarchical binary network structure in conjunction with optimized material combination provides ultrafast, continuous, and smooth electron transportation channel and non‐nucleation barrier sites to direct and confine Li deposition. It also offers outstanding mechanical strength and toughness to support massive Li deposition and buffer the internal stress fluctuations during long‐term repeated Li stripping/plating thereby minimizing fundamental issues of dendrite formation and volume change even under ultrafast charging/discharging rates. As a result, the composite anode using this hierarchical host can work smoothly at an unprecedented high current density of 40 mA cm‐2 over 1000 plating/stripping cycles with low overpotential (<120 mV) in symmetric cells. The as‐constructed full cell, paired with LiNi0.5Co0.2Mn0.3O2 cathode, also exhibits excellent rate capability and high‐rate cycling stability.

AbstractAll‐inorganic cesium lead bromide (CsPbBr3) perovskite solar cells have attracted enormous attention owing to their outstanding stability in comparison with organic–inorganic hybrid devices. The greatest weakness for inorganic CsPbBr3 solar cells is their lower power conversion efficiencies, mainly arising from inferior light‐absorbance range and serious charge recombination at interfaces or within perovskite films. To address this issue, the lattice doping of lanthanide ions (Ln3+ = La3+, Ce3+, Nd3+, Sm3+, Eu3+, Gd3+, Tb3+, Ho3+, Er3+, Yb3+, and Lu3+) into CsPbBr3 films for all‐inorganic solar cells free of hole‐transporting materials and precious metal electrodes is presented. Arising from the enlarged grain size and prolonged carrier lifetimes upon incorporating Ln3+ ions into perovskite lattice, the performances of these inorganic CsPbBr3 solar cell devices are significantly enhanced, achieving a champion efficiency as high as 10.14% and an ultrahigh open‐circuit voltage of 1.594 V under one sun illumination. Meanwhile, the nearly unchanged efficiency upon persistent attack by 80% RH in air atmosphere over 110 d and enhanced thermal stability at 80 °C over 60 d provide new opportunities of promoting commercialization of all‐inorganic CsPbBr3 perovskite solar cells.
Inter‐country adoption in Australia: Examining the factors that drive the practice and implications for policy reform
Authors: Hilferty Fiona , Katz Ilan 
Published: September 2018

AbstractThe article presents the findings of an international literature review conducted to examine the factors that drive inter‐country adoption rates within both sending and receiving countries. The authors then consider the implications of these findings for inter‐country adoption policy reform in Australia. The evidence in the literature highlights a distinction between the factors that drive ICA in sending and receiving countries. Factors that drive the practice in sending countries relate to structural forms such as socio‐economic and political conditions. In contrast, it is the growing demand for a child from infertile couples that drives the practice in receiving countries. The article then considers the challenges of domestic policy reform undertaken to increase numbers of inter‐country adoptions in a context of global decline.
Pervasive Delocalisation Error Causes Spurious Proton Transfer in Organic Acid–Base Co‐Crystals

Published: September 2018

AbstractDispersion‐corrected density‐functional theory (DFT‐D) methods have become the workhorse of many computational protocols for molecular crystal structure prediction due to their efficiency and convenience. However, certain limitations of DFT, such as delocalisation error, are often overlooked or are too expensive to remedy in solid‐state applications. This error can lead to artificial stabilisation of charge transfer and, in this work, it is found to affect the correct identification of the protonation site in multicomponent acid–base crystals. As such, commonly used DFT‐D methods cannot be applied with any reliability to the study of acid–base co‐crystals or salts, while hybrid functionals remain too restrictive for routine use. This presents an impetus for the development of new functionals with reduced delocalisation error for solid‐state applications; the structures studied herein constitute an excellent benchmark for this purpose.

ABSTRACTA novel kind of conductive self‐assembled colloid particles (CPs) was prepared from poly(3‐thiophenecarboxylic acid) (PTPCA) and chitosan (CS) via electrostatic interaction and π–π interaction. The resultant CPs were then cast on the electrode surface to provide a platform for fabricating high‐sensitive biosensor. It should be noted that the good conductivity of PTPCA can accelerate the electron transfer and facilitate the signal transduction from the CP film to the underlying electrode. This advantage endowed the biosensor with high sensitivity for H2O2 detection. Under the optimal conditions, a linear range from 1 × 10−11 to 1 × 10−5 mol L−1 with a detection limit of 3 × 10−12 mol L−1 was obtained for H2O2 detection. The biosensor can be used to detect H2O2 in commercial disinfector with satisfactory results. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46764.

Published: September 2018

ABSTRACTHighly flexible and visibly transparent yellow–green fluorescent poly(vinyl alcohol) (PVA) based nanocomposite (NC) films with rubidium zincate (Rb2ZnO2) nano impregnates were developed through aqueous solution casting. The introduced rubidium zincate nanofillers impart UV shielding properties to PVA host, through UV to visible (fluorescent yellow–green) photon cutting. The rubidium zincate nanofiller impregnated PVA systems were also characterized for their structural, morphological, optical, and electrical behaviors by various analytical tools. The Fourier Transform Infrared (FTIR) and X‐ray diffraction (XRD) studies shed light on the changes in gross structural properties of PVA. WhileScanning Electron Microscopic (SEM) profiles support uniform filler dispersions, which aid high visible transparencies. Further, the UV–visible spectral measurements depict the changes in electronic band structure that validates novel fluorescent emission properties, established through fluorescent emission studies. The NC films show excellent visible transparency (72–84%), near hydrophobic surface wettabilities (ϴ = 82°–93°) and enhanced charge conduction, in addition to high flexibilities and UV photons induced fluorescent emission (
λEmi=585 nm). The yellow–green luminescent, Rb2ZnO2 nanofillers reinforced PVA NC films are effective spectral manipulators, which may be used as competent packaging materials for photonic display devices and to extend the short wavelength limit of solar cells. © 2018 Wiley Periodicals, Inc.

ABSTRACTThis study proposes producing sandwich composites that have functionalities in addition to good mechanical properties. Flexible polyurethane (FPU) foam is used as the core, whereas nonwoven fabrics are used as the top and bottom panels. The functionalities, including flame‐retardant (FR) efficacy, acoustic absorption, and electromagnetic shielding effectiveness (EMSE), help in expanding the application fields. In this study, FR agent is added to FPU foam to form the core, while the low‐melting point polyethylene terephthalate (LPET) nonwoven fabric with/without carbon fiber (CF) fabric is used as panels. One‐step molding and hot pressing are used to make these materials into LPET/FPU and CF‐LPET/FPU sandwich composites. The cell structure of the FPU foam is examined, after which the limit oxygen index (LOI), the compression modulus, and heat insulation efficacy of LPET/FPU sandwich composites are examined, thereby examine the influence of FR agent. The test results show that the mechanical properties of sandwich composites are dependent on the amount of FR agent. Using 50 wt %, FR agent provides LPET/FPU sandwich composites with an optimal LOI of 28. In addition, the combination of CF fabric further provides CF‐LPET/FPU composite sandwich with the maximum acoustic absorption coefficient of 0.90376 and an optimal EMSE of 50 dB. The proposed sandwich composites have functionalities of FR efficacy, acoustic absorption, heat insulation, and EMSE and thus are qualified for protective partitions used in karaoke and kindergartens. © 2018 Wiley Periodicals, Inc.

Published: September 2018

ABSTRACTOptical and magnetic responsive deforming multilayered films with rapid deforming recovery property were successfully fabricated by electrospinning technology. Polyvinyl alcohol (PVA)/liquid crystal (LC) 5CB (4‐cyano‐4'pentylbiphenyl)/graphite fiber film was orderly collected on the thermoplastic polyurethanes (TPU) substrate film by parallel electrode electrospinning method. Graphite and nano‐magnetic particles had been added to endue it with optical and magnetic responsibility. Evaluated by a customized 3D‐printed platform, the deforming multilayered film shows its high deforming recovery speed. Therefore, the proposed deforming multilayered films can be applied in the field of bionic control with the advantage of rapid optical and magnetic responsibility, nontoxicity, and simple fabrication approach. © 2018 Wiley Periodicals, Inc.

PEEK/diatomite composites byin situpolymerization: Synthesis, characterization and fundamental properties
Authors: Liu Yifan , Huang Sa , Tan Jie , Wang Zhaoyang , Jiang Zilong , Zhang Haibo 
Published: September 2018

ABSTRACTIn this study, poly (ether ether ketone)/diatomite composites (PEEK/diatomite composites) were prepared by in situ polymerization. In contrast to the direct melt‐compounding method, particles are produced with up to 25 wt % higher filler content by the in situ polymerization method. We found that filling with diatomite improved the mechanical properties of PEEK by about 15%. Scanning electron microscopy revealed that the diatomite particles are uniformly dispersed in the PEEK matrix. Furthermore, the PEEK resin penetrates into the diatomite channels to form interpenetrating organic–inorganic network structures. The thermal stabilities of the composites were studied by thermogravimetric analysis, which revealed that they possess excellent thermal stabilities; these PEEK/diatomite composites exhibit higher decomposition‐onset temperatures than virgin PEEK and lower rates of decomposition. This is attributable to interactions between the diatomite and the matrix, with the diatomite acting as a physical barrier between the polymer and the superficial zone where polymer combustion takes place. © 2018 Wiley Periodicals, Inc.

Leptin is a proinflammatory cytokine that plays an important role in energy homeostasis. Emerging evidence suggests that leptin levels are altered in children with autism spectrum disorder (ASD); however, this has not been studied prospectively. Rapid growth during infancy and early childhood has been implicated in ASD, but the evidence is inconsistent. As leptin is involved in growth and is a potential risk factor for ASD, we explored the associations between (a) cord, early childhood leptin and ASD; and (b) birth weight for gestational age, early childhood weight gain, and ASD. We also assessed the mediating role of leptin in the relationship between weight gain during infancy and ASD. This study was conducted in a sample of 822 subjects from the Boston Birth Cohort. ASD was defined from diagnostic codes in electronic medical records. Extremely rapid weight gain during infancy was associated with a greater ASD risk and this persisted after adjusting for potential confounders (aOR: 3.11; 95% CI: 1.37, 7.07). Similarly, children that had higher plasma leptin levels, prior to ASD diagnosis, had an increased ASD risk in both unadjusted and adjusted models (aOR: 7.87; 95% CI: 2.06, 30.04). Further, early childhood leptin indirectly mediated the relationship between rapid weight gain and ASD. No associations were found between birth weight for gestational age, cord leptin and risk of ASD. Our findings provide a basis to further explore whether the combination of early life growth pattern and a biomarker such as leptin can predict ASD earlier. Autism Res 2018, 11: 1416–1431. © 2018 International Society for Autism Research, Wiley Periodicals, Inc.Lay SummaryIs early life growth and a biomarker leptin related to ASD risk? To answer this question, we followed 822 children from birth and found that those who gained weight very quickly in infancy, had higher leptin levels in early childhood, had a greater chance of later ASD diagnosis. More research is needed to see if infant's weight gain pattern along with a biomarker (such as leptin) can be used to identify children with ASD sooner.

AbstractIn the present study, we aimed to develop a reliable screening method based on liquid chromatography coupled with tandem mass spectrometry (LC–MS/MS) for the detection and quantification of naproxen, methyltestosterone and 17α‐hydroxyprogesterone caproate residues. The target analytes were extracted from samples of eel, flatfish and shrimp using acetonitrile with 1% acetic acid, followed by liquid–liquid purification with n‐hexane. Chromatographic separation was achieved on a reversed‐phase analytical column using 0.1% formic acid containing 10 mm ammonium formate in distilled water (A) and methanol (B) as mobile phases. All the matrix‐matched calibration curves were linear (R2 ≥ 0.99) over the concentration range of the tested analytes. Recovery at three spiking levels (0.005, 0.01 and 0.02 mg/kg) ranged from 68 to 117% with intra‐ and inter‐day precisions <10%. Five market samples for each matrix (eel, flatfish and shrimp) were collected and tested for method application. In summary, the proposed method is feasible to screen and quantify the analytes with high selectivity in aquatic food products meant for human consumption.

AbstractDepression is the largest cause of disability worldwide, affecting 350 million people. Notwithstanding that clinical trials demonstrate antidepressants efficacy, the efficient response can vary individually concerning therapeutic dosage. Although important, plasma levels monitoring remains an analytical challenge whereas clean‐up and pre‐concentration represent critical steps. Therefore, this study aims to develop, optimize and validate a method for fluoxetine determination in human plasma, employing a laboratory‐made device consisting of a PDMS stir bar sorptive for extraction, coupled with high‐performance liquid chromatography–fluorescence detection (SBSE–HPLC–FD). Optimization involved sorption–desorption steps. For sorption, temperature and time were assessed by factorial and central composite design approaches, taking into account the desirability and the response surface results, with stirring speed also examined. For desorption kinetics and ultrasonic and magnetic stirring mode were evaluated. The proposed method after validation was robust, linear (25.00–1000.00 ng mL−1, R2 > 0.98) and presented good intra‐ (RSD 4.18%) and inter‐day‐assay (RSD 11.60%) precision and accuracy (recovery 109.60%), allowing reliable quantitation without interference. The method was successfully applied to real samples. SBSE–HPLC–FD could represent a feasible alternative with good cost–benefit for low‐volume samples and therapeutic drug monitoring, as well as contributing to correlation studies between plasma fluoxetine levels and clinical response, which is still little studied.

AbstractThe preparation of water‐soluble, N‐heterocyclic‐carbene‐stabilized Au–Pd alloy nanoparticles by a straightforward ligand exchange process is presented. Extensive analysis revealed excellent size retention and stability over years in water. The alloy nanoparticles were applied as biomimetic catalysts for aerobic oxidation of d‐glucose, for which monometallic Au and Pd nanoparticles showed no or negligible activity. The alloy nanoparticles were further applied as titania‐supported heterogeneous catalysts for the mild hydrogenation of nitroarenes and the semihydrogenation of 1,2‐diphenylacetylene with a solvent‐dependent selectivity switch between E‐ and Z‐stilbene.

Published: September 2018

AbstractGold‐catalysed oxidative cyclisation reactions of ynamides offer great promise in γ‐lactam synthesis but are limited by preferential over‐oxidation to form α‐keto imides. Evaluating the factors that might limit N‐cyclisation pathways led to effective gold‐catalysed conditions that allow access to different fused γ‐lactams on changing the ynamide N‐substituent and accommodate previously incompatible substitution patterns. New and efficient methods for the synthesis of functionalised 3‐aryl indoles and cyclohepta[c]pyrrol‐1‐one derivatives are presented. These conditions illustrate the complementarity of gold catalysis to other metals.

Published: September 2018

AbstractThe kinetics of metabolic processes can be assessed, in real time by means of MR hyperpolarized (HP) metabolites. [1‐13C]pyruvate, hyperpolarized by means of d‐DNP, is, by far, the substrate most widely applied to the investigation of several pathologies characterized by deregulated glycolytic metabolic networks, including cancer. Hyperpolarization of [1‐13C]pyruvate by means of the cost effective, fast and easy to handle PHIP‐SAH (para‐hydrogen induced polarization‐side arm hydrogenation) method opens‐up a pathway for the application of HP metabolites to a wide range of cancer‐related studies. Herein, we report the first application of PHIP‐SAH hyperpolarized [1‐13C]pyruvate in the investigation of upregulated glycolysis in two murine breast cancer cell lines (168FARN and 4T1). The results obtained using HP pyruvate have been validated with a conventional biochemical assay and are coherent with previously‐reported lactate dehydrogenase activity measured in those cells.
