Authors: Wang Xin , Song Jun , Qu Junle 
Published: August 2018

AbstractThe two‐dimensional material antimonene was first reported in 2015. Subsequently, its unique properties, including enhanced stability, high carrier mobility, and band‐gap tunability, were predicted theoretically. These theoretical results have motivated experimental confirmation and thus a better understanding of this new material. Recently, the preparation of antimonene and its attempted use in several applications have attracted extensive attention. This Minireview focuses on both the experimental preparation and practical applications of antimonene, including the results of recent research on novel methods of preparing antimonene and its potential applications in optoelectronic devices, electrocatalysis, energy storage, and cancer therapy. Moreover, it provides insight that could further improve the preparation of antimonene and also describes numerous opportunities for application.
Study on the anti‐biofouling effects of the grafted polyamide 6 fibers by several vinyl chemicals
Authors: Saleh N. S. , Ostad Movahed S. , Attarbashi F. 
Published: August 2018

ABSTRACTThe biofouling is any non‐desirable accumulation and growth of living matters on the material surfaces. Four grafting agents, Acrylic acid (AA), 2‐hydroxyethyl methacrylate (HEMA), 2‐dimethyl amino ethyl methacrylate (DMAEMA), and Methyl acrylate (MA) were grafted on a polyamide fiber (PA6) with two techniques “simultaneous UV irradiation and grafting” (SUVIG) and “pre‐UV irradiation (PUVI). It revealed that all used grafting chemicals grafted on the PA6 fiber surface efficiently. The SEM micrographs showed that the surface of the ungrafted PA6 fiber was relatively smooth, but for the grafted fibers, they were coarse and the grafted chemicals distributed on the PA6 surface heterogeneously. The grafting of the used grafting agents on the PA6 fiber surface increased the glass transition temperature of the PA6 fiber. The grafting of the PA6 fiber altered its crystallinity depending on the type of the grafting agent. With except of the MA, the hydrophilicity of the grafted PA6 fibers was higher than the ungrafted PA6 fiber. The grafting efficiency percentages and degrees were remarkably higher for the PUVI technique when compared with the SUVIG technique. The results of the biological tests showed that the MA was a suitable grafting agent for increasing anti‐biofouling property of the PA6 fiber. © 2018 Wiley Periodicals, Inc. J. Appl. Polym.

Published: August 2018

ABSTRACTSuperhydrophobic and superoleophilic cotton fabric was successfully prepared with fluorinated silica sol via a facile sol–gel method. A fluorinated polymeric sol–gel precursor (PHFBMA‐MTS) was synthesized via free‐radical polymerization by using hexafluorobutyl methacrylate (HFBMA) in the presence of (3‐mercaptopropyl)trimethoxysilane (MTS) as the chain transfer agent, which led to the formation of fluoropolymer with alkoxysilane end groups. Then the fluorinated silica sol was prepared by introducing PHFBMA‐MTS as the co‐precursor of tetraethylorthosilicate (TEOS) in the sol–gel process with ammonium hydroxide as the catalyst, which was then used to fabricate superhydrophobic and superoleophilic fabric coatings through a simple dip‐coating method. The coated fabrics showed superhydrophobic property with a high water contact angle of 154.1° and superoleophilic property with an oil contact angle of 0°. Moreover, the coated fabrics still kept superhydrophobicity even after ultrasonic treatment, as well as for organic solutions, acidic solutions. Thus, the coated fabrics were successfully applied to separate oil–water mixture with separation efficiency up to 99.8%. More importantly, the separation efficiency had no significant change after 20 cycles of oil–water separation. These present a simple, low‐cost, and durable approach to achieve industrialized application of coated fabrics in oil–water separation. © 2018 Wiley Periodicals, Inc. J. Appl. Polym.

Published: August 2018

ABSTRACTThree dimensional (3D) printing holds strong potential for the formation of a new class of multifunctional nanocomposites. Therefore, both the nanocomposites and 3D printing communities need to make more collaborations and innovations for developing and processing of new polymers and composites to get benefit of functionalities of 3D printed nanocomposites. The contribution of this paper is the creation of 3D printable filaments from conductive polymer nanocomposites using a melt mixing process. Multi‐walled carbon nanotubes (MWNTs) and high‐structured carbon black (Ketjenblack) (KB) were incorporated into polylactic acid. The percolation threshold of MWNT composites is 0.54 wt % and of KB composites is 1.7 wt % by four‐point resistance measurement method. In the similar melt mixing process, there was no dependence of diameter of produced 3D printer filaments on the MWNT loading, instead the diameter was dependent on the KB loading and increased with increasing the filler amount. The conductivity of extruded filaments from 3D printer in low filler contents decreases with increasing extruder temperature, yet in higher filler contents there is no effect of extruder temperature on conductivity. Finally, the resistance decreases exponentially with the increase of cross‐sectional area of 3D printed tracks. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47040.

Authors: Shiwani H , Baxter P , Taylor E , Bailey M A , Scott D J A 
Published: August 2018

Abstract

Background
Popliteal artery aneurysms (PAAs) comprise up to 85 per cent of all peripheral aneurysms. Few longitudinal studies track their progression. This study aimed to track the growth of asymptomatic PAAs in a hospital-based ultrasound service, and compare models of aneurysm growth.

Methods
This retrospective single-centre cohort study included patients who had a PAA on arterial duplex ultrasound imaging of the lower limbs between 1 January 2011 and 1 January 2016. Progression of PAA size and progression to event or intervention were the primary outcome measures.

Results
Some 282 images were analysed: 47 limbs with PAA were included in a cohort of 32 patients (15 had bilateral PAAs). Twenty patients also had an abdominal aortic aneurysm (AAA). Linear multilevel modelling estimated that PAA growth was 2·4 (95 per cent c.i. 1·6 to 3·7) mm a year. Growth was estimated at 0·8 (0·1 to 1·5) mm per year in patients without an AAA and 3·5 (2·9 to 4·2) mm per year in those with a known AAA (previous open repair, previous endovascular aneurysm repair or AAA under surveillance) (P &lt; 0·001).

Conclusion
Growth rates of PAA were heterogeneous but were optimally predicted by multilevel modelling. Patients with an existing AAA may have faster PAA progression than those without.
Methods and approaches for determination and enantioseparation of (RS)‐propranolol
Authors: Batra Sonika , Bhushan Ravi 
Published: August 2018

AbstractPropranolol, a β‐adrenergic receptor antagonist, is a chiral compound that is marketed as a racemate, but only the (S)‐(−)‐enantiomer is responsible for the β‐adrenoceptor blocking activity. Different chromatographic methods have been applied for separation and determination of enantiomers of (RS)‐propranolol. In this article a review is presented on different liquid chromatographic methods used for enantioseparation of (RS)‐propranolol, using both HPLC and TLC. In addition, some aspects of enantioseparation under achiral phases of liquid chromatography have been briefly mentioned.
Analyzing the role of social capital in sustainable environmental governance: A case study on Piranshahr
Authors: Rahnama Mohammad Rahim , Sharifzadeh Aghdam Ebrahim 
Published: August 2018

AbstractThe main objective of the present study was to investigate the role of social capital in sustainable environmental governance in relation with formation of sustainable urban residential neighborhoods, the cause of inefficiency of some of them in terms of integrated urban management, and empowering them. As the study's purpose required, the study's method was applied, and regarding the nature, it was an analytical descriptive study. According to its title, the data collection method was survey using questionnaire technique. The study population consisted of the residents of Piranshahr in 2016. To select them, Cochran formula was employed, and the sample size was determined to be 382 individuals. In so doing, stratified random sampling method was utilized. The collected data were analyzed using LISREL and SPSS software packs and through exploratory and confirmatory factor analysis and structural equation model. The results of the study indicated that the indices utilized in the study had a significant effect on the environmental sustainability of the urban neighborhoods. They also showed that the citizens' beliefs in that they, as local‐oriented social capital, influence the decisions and that the urban management requires their participation in urban governance had a strong positive effect on sustainable development of the neighborhoods. These effects are so strong that the governors have been effective in unsustainability of the urban neighborhoods by ignoring the role of social capital. It was also concluded that environmental sustainability indices were not favorable enough.
Multinationals and sustainable development: Does internationalization develop corporate sustainability of emerging market multinationals?
Authors: Park Sang‐Bum 
Published: August 2018

AbstractBased on theories of attention and institution, this paper examines how the internationalization of emerging market multinationals (EMNEs) affects their corporate sustainability (CS). A contrasting perspective with respect to the dual effects of internationalization on sustainability strengths (being good) and sustainability concerns (being bad) is developed. On one hand, it is argued that internationalization improves CS strengths because EMNEs that rely on foreign sales are motivated to adopt CS as a global business norm. Such norm‐conformity overcomes the liability of origin and legitimacy challenge in foreign markets. On the other hand, it is contended that internationalization also increases CS concerns because subsidiaries of EMNEs are susceptible to being decoupled from the headquarters' CS policy. The results show that internationalization can be both good and bad for CS. Thus, it can be misleading to simply say that there is either a positive or a negative relationship between internationalization and CS.
Survival effect of different lymph node staging methods on ovarian cancer: An analysis of 10 878 patients
Authors: Wang Jieyu , Li Jun , Chen Ruifang , Lu Xin 
Published: August 2018

AbstractBackgroundTo compare the survival impact of several lymph node staging methods and therapeutic role of lymphadenectomy in patients with epithelial ovarian cancer who had undergone lymphadenectomy.MethodsData were retrospectively collected from the Surveillance, Epidemiology, and End Results program between 1988 and 2013.ResultsAn increasing number of resected lymph nodes (RLNs) was associated with a significant improvement in survival of FIGO stage II and III disease. However, for FIGO stage IV patients, better survival was not significantly associated with a more extensive lymphadenectomy. A higher lymph node ratio (LNR) and log odds of positive lymph nodes (LODDS) were associated with poorer survival regardless of stage. Nevertheless, four‐category classification of LODDS was more suitable for stage IV patients when three‐category classification was compatible with stage I‐III disease. Multivariate analysis demonstrated that LODDS and LNR were significant independent prognostic factors, but not RLN classification.ConclusionSixteen to thirty RLNs are recommended for stage I disease. For stages II and III patients, the more lymph node excision, the better the prognosis. However, lymphadenectomy was nonessential for stage IV patients. Considering staging methods, for stages II and III patients, three‐category classification of LODDS was recommended to evaluate the prognosis. For stage I and IV, three‐category classification of positive LNR was idoneous.

AbstractOvarian cancer is one of the most common gyneacologic malignancies, with high morbidity and high mortality. Hsa‐miR‐122‐5p (miR‐122) has been reported with tumor‐suppressing roles in various cancers. In this study, miR‐122 was overexpressed in ovarian cancer cells, and phenotypic experiments demonstrated that miR‐122 inhibited migration and invasion in SKOV3 and OVCAR3 cells. MiR‐122 also suppressed epithelial mesenchymal transition (EMT), evidenced by expression changes of E‐cadherin, vimentin, matrix metalloproteinase (MMP)2, and MMP14. Prolyl‐4‐hydroxylase subunit alpha‐1 (P4HA1) was identified as a target of miR‐122, and downregulated by miR‐122. MiR‐122‐induced the elevation of migration, invasion, and EMT were recovered by P4HA1. Additionally, miR‐122 restrained the tumor metastasis of SKOV3 cells in peritoneal cavity of nude mice. In summary, we demonstrated that miR‐122 inhibited migration, invasion, EMT, and metastasis in peritoneal cavity of ovarian cancer cells by targeting P4HA1 for the first time, which shed lights on the discovery of miR‐122 and P4HA1 as possible potential diagnostic markers and therapeutic targets for ovarian cancer.

Published: August 2018

AbstractOne of the pioneering examples of chemoenzymatic cascades in water such as the palladium‐catalysed Suzuki‐cross coupling followed by an enzymatic reduction has been revisited by the employment of a medium containing Deep Eutectic Solvents (DESs) for the catalytic performance. Thus, the unique properties of these neoteric solvents enabled to reach high substrate concentration for the overall process. Moreover, both isolated enzymes and whole cells exhibited excellent activities which allowed to obtain a set of chiral biaryl alcohols in good yields and very high enantiomeric excess (>99 %).

Published: August 2018

AbstractAzocarboxamides occupy a special place among azo ligands owing to their versatility for metal coordination. Herein ruthenium complexes with two different azocarboxamide ligands that differ in the presence (or not) of a coordinating pyridyl heterocycle are presented. By making full use of the O,N(amide), N(azo), and N(pyridyl) coordinating sites, the first diruthenium complex that is bridged by an azo ligand containing two different binding pockets was obtained. Moreover, it was conclusively proven that, in the mononuclear complexes, oxidation at the ruthenium center leads to a complete change of coordination at the chelating binding pocket. The complexes were characterized by NMR spectroscopy, mass spectrometry, and single‐crystal X‐ray diffraction. Additionally, the mechanism of the aforementioned redox‐triggered change in the chelating binding pocket and the electronic structures of all the complexes were investigated by a combination of electrochemistry, UV/Vis/NIR/EPR spectroelectrochemistry, and DFT calculations. This is first instance in which a redox‐driven change in the complete chelating binding pocket has been observed in a ruthenium complex as well as with azo‐based ligands. These results thus show the potential of these versatile azocarboxamide ligands to act as redox‐driven switches with possible relevance to electrocatalysis.
An extension of the industrial corporate social responsibility practices index: New information for stakeholder engagement under a multivariate approach

Published: August 2018

AbstractThe aim of this paper is to extend the Industrial Corporate Social Responsibility Practices Index proposed for the 10 main industries in the 39 sectors of activity that comprise them. This extension will provide more detailed information on CSR practices at the industrial level, especially about sustainable development and environmental concerns. In addition, this paper stablishes an aggregate measure of industrial classification and mimetic typologies. It will tabulate the overall impact that the economic activity of a company has on society and environment. Thereby, the relationships between these indicators and the mimetic institutional forces are studied, testing these forces indicate that companies from sectors considered to have greater impact/risk have higher corporate social responsibility (CSR) scores than companies from other sectors. Additionally, using the MetaBiplot statistical multivariate technique, which by the comparison and integration of several subspaces provides a global view of sustainability at a sectoral level, it was found that the most polluting companies with the highest environmental risks—forestry and paper, mining, oil and gas producers, gas, water, and multi‐utilities, tobacco and electricity sectors—show their predilection for environmental policies and reports, human rights, and stakeholder participation. Moreover, the less polluting companies—banks, insurance, media, telecommunications, real state, and general retailers—are more intensive on staff and implement policies aimed at favoring: the personal and work‐life balance with systems for employee training and promotion; the equal opportunities and participation; the maintenance of good customer and supplier relations; and the fight to counteract bribery.
Ion‐exchange Microemulsions for Eliminating Dilute Interferences in Potentiometric Determinations
Authors: Apichai Sutasinee , Wang Lu , Pankratova Nadezda , Grudpan Kate , Bakker Eric 
Published: August 2018

AbstractWe report here for the first time on the use of functional microemulsions in potentiometric assays to remove dilute interferences from solution when measuring high concentrations of analyte. The microemulsions are similarly formulated to the ion‐selective membrane used in the measurement and act as sacrificial material. They are here stabilized by the triblock copolymer pluronic F‐127 and contain the chloride salt of the tridodecylmethylammonium cation, which also serves as anion‐exchanger in the membrane electrode. Both membrane and microemulsion are preconditioned with chloride. If an anionic interference is present at moderate concentration, the rapid equilibration with the functionalized microemulsion results in a quantitative removal. The principle is explored with salicylate as common interference in the detection of chloride in physiological samples. The data agree well to an equilibrium ion‐exchange model for the microemulsion. Salicylate levels up to millimolar can be effectively removed. Unfortunately, quaternary ammonium salt from the microemulsion is found to contaminate the ion‐selective membrane phase. Indeed, a cation‐exchanging valinomycin membrane in contact with concentrated anion‐exchanging microemulsions shows a large potential increase. This indicates that the membrane changes from cation to anion permselectivity. This contamination of the membrane by the microemulsion phase must be overcome for a practical application of the approach.

AbstractRecently, the advences of Industry 4.0 have paved the way for a systematical deployment of the smart grid (SG) to manage continuously growing energy demand of the 21st century. This even allows the fourth stage of the industrial revolution in the power sector, which is known as the smart grid industry (SGI) 4.0. In SGI 4.0, the industrial wireless sensor networks (WSNs) and the Internet of Things are envisioned as key promising communication technologies for monitoring various SG applications due to their large‐scale coverage, fault tolerance characteristics, and cost reduction. However, highly dynamic nature of the SG environments brings several unique challenges caused by systems and operating devices. This results in hampering the quality‐of‐service communication requirements for WSNs‐based SG applications. In SGI 4.0, the routing infrastructure not only requires a reliable but also fulfills the communication requirements of diverse SG applications. Thus, a sophisticated, reliable and QoS‐aware multi‐hop communications network architecture enabling a real‐time exchange of data for various WSNs‐based SG applications is essential in SGI 4.0. Hence, this paper proposes a novel bio‐inspired self‐optimized butterfly mating optimization‐based data gathering routing scheme called Self‐optimized Intelligent routing protocol (SIRP) for WSNs‐based SG applications. The extensive simulations reveal that the proposed scheme achieves its defined goals compared to existing routing schemes designed for WSNs‐based applications.
