Investigation of oxidation resistance of two-dimensional (2D) materials is critical for many of their applications because 2D materials could have higher oxidation kinetics than their bulk counterparts due to predominant surface atoms and structural distortions. In this study, the oxidation behavior of high-quality boron nitride (BN) nanosheets of 1-4 layers thick has been examined by heating in air. Atomic force microscopy and Raman spectroscopy analyses reveal that monolayer BN nanosheets can sustain up to 850 °C, and the starting temperature of oxygen doping/oxidation of BN nanosheets only slightly increases with the increase of nanosheet layer and depends on heating conditions. Elongated etch lines are found on the oxidized monolayer BN nanosheets, suggesting that the BN nanosheets are first cut along the chemisorbed oxygen chains and then the oxidative etching grows perpendicularly to these cut lines. The stronger oxidation resistance of BN nanosheets makes them more preferable for high-temperature applications than graphene.

In this work we present the definition of strong fuzzy subsethood measure as a unifiying concept for the different notions of fuzzy subsethood that can be found in the literature. We analyze the relations of our new concept with the definitions by Kitainik ( [20]), Young ( [26]) and Sinha and Dougherty ( [23]) and we prove that the most relevant properties of the latter are preserved. We show also several construction methods. © 2014 Old City Publishing, Inc.

Purpose – The purpose of this paper is to develop and empirically test a model of brand engagement. More specifically, the aim is to evaluate both antecedents and consequences of brand engagement, from a management perspective. Design/methodology/approach – A quantitative survey of 403 firms is undertaken to test the model. Structural equation modelling (SEM) is used to estimate the parameters of the model. Findings – A reliable and valid measure of brand engagement is established. The SEM model works well, in terms of goodness of fit indices. The results demonstrate that there are major brand performance benefits (consequences) of brand engagement. Additionally, and important for the practical implications, the results show that brand orientation is a major antecedent to brand engagement. Research limitations/implications – The study needs to be replicated in other countries, with scope to add other explanatory variables for influencing brand engagement. The results have considerable practical benefits for guiding the introduction of measures to enhance brand engagement. Originality/value – The study builds on earlier (mainly consumer) conceptual approaches to brand engagement, but goes further in that it provides empirical evidence about the nature, antecedents and consequences of brand engagement and further, offers a management rather than consumer perspective. Essentially, the study reveals a new perspective of factors that encourage firms to connect/engage their brands with consumers. Brand engagement is a dual concept, reflecting both a consumer and a firm perspective.

This book offers a way to predict which brand a buyer will purchase. It looks at brandperformance within a product category and tests it in different countries with verydifferent cultures. Following the Predictive Brand Choice (PBC) model, this book seeks to predict a consumer’s loyalty and choice. Results have shown that PBC can achieve a high level of predictive accuracy, in excess of 70% in mature markets. This accuracy holds even in the face of price competition from a less preferred brand.PBC uses a prospective predicting method which does not have to rely on a brand’spast performance or a customer’s purchase history for prediction. Choice data isgathered in the retail setting – at the point of sale. The Strategy of Global Brandingand Brand Equity presents survey data and quantitative analyses that prove themethod described to be practical, useful and implementable for both researchers and practitioners of commercial brand strategies.

It remains a huge challenge to create advanced polymeric materials combining high strength, great toughness, and biodegradability so far. Despite enhanced strength and stiffness, biomimetic materials and polymer nanocomposites suffer notably reduced extensibility and toughness when compared to polymer bulk. Silk displays superior strength and toughness via hydrogen bonds (H-bonds) assembly, while cuticles of mussels gain high hardness and toughness via metal complexation cross-linking. Here, we propose a H-bonds cross-linking strategy that can simultaneously strikingly enhance strength, modulus, toughness, and hardness relative to polymer bulk. The H-bond cross-linked poly(vinyl alcohol) exhibits high yield strength (140 MPa), reduced modulus (22.5 GPa) in nanoindention tests, hardness (0.5 GPa), and great extensibility (40%). More importantly, there exist semiquantitive linear relationships between the number of effective H-bond and macroscale properties. This work suggests a promising methodology of designing advanced materials with exceptional mechanical by adding low amounts (1.0 wt %) of small molecules multiamines serving as H-bond cross-linkers.
Franchisee-based brand equity: The role of brand relationship quality and brand citizenship behavior

Despite the evidence that brand management is core to the success of franchising businesses, limited empirical work has focused on branding in such business-to-business (B2B) exchanges. Integrating social exchange theory and the identity-based brand management framework, this study proposes that brand relationship quality is crucial in promoting franchisee brand citizenship behavior that can enhance brand equity attributable to franchisees, thereby advancing a model of '. franchisee-based brand equity' (FBBE). Survey results from 352 franchisees in franchised B2B exchanges suggest that brand relationship quality promotes brand citizenship behavior, thereby enhancing FBBE. Additionally, moderated mediation analysis indicates that the indirect effect of brand relationship quality on FBBE via brand citizenship behavior is stronger when franchisor competence is high. However, franchisor-franchisee relationship duration has no moderating effects on these relationships. The findings of this study have implications for franchising practitioners that are interested in understanding the role of brand relationship management in promoting franchisee brand citizenship behavior and FBBE.
