The synthesis of highly uniform mesoporous silica nanospheres (MSNs) with dendritic pore channels, particularly ones with particle sizes below 200 nm, is extremely difficult and remains a grand challenge. By a combined synthetic strategy using imidazolium ionic liquids (ILs) with different alkyl lengths as cosurfactants and Pluronic F127 nonionic surfactants as inhibitors of particle growth, the preparation of dendritic MSNs with controlled diameter between 40 and 300 nm was successfully realized. An investigation of dendritic MSNs using scanning electron microscopy (SEM), transmission electron microscopy (TEM), and nitrogen physisorption revealed that the synthesis of dendritic MSNs at larger size (100-300 nm) strongly depends on the alkyl lengths of cationic imidazolium ILs; while the average size of dendritic MSNs can be controlled within the range of 40-100 nm by varying the amount of Pluronic F127. The Au@MSNs can be used as a catalyst for the reduction of 4-nitrophenol by NaBH4 into 4-aminophenol and exhibit excellent catalytic performance. The present discovery of the extended synthesis conditions offers reproducible, facile, and large-scale synthesis of the monodisperse spherical MSNs with precise size control and, thus, has vast prospects for future applications of ultrafine mesostructured nanoparticle materials in catalysis and biomedicine.

While China ' s outward direct investments continue to soar, many Chinese fi rms reportedly face social resistance in host countries during the internationalization process. We explore this phenomenon from a country-of-origin ( COO ) perspective using Fiske and colleagues' (Fiske, Cuddy, Glick, & Xu, 2002 ;Fiske, Xu, Cuddy, & Glick, 1999 ) stereotype content model. Our fi ndings from a recent case in New Zealand show that China ' s COO emerges as a key variable infl uencing how local actors view Chinese investors. Specifi cally, despite China ' s signifi cant economic and social developments over the past decades, it suffers from a somewhat negative country image in two stereotype dimensions: competence and warmth. This leads to a perception by local actors that Chinese fi rms are of low quality, which explains the source of resistance in society. To address such a liability of origin, Chinese fi rms must learn to deal with this form of stereotypical judgment encountered in a host environment. Further contributions and limitations of the study are discussed in the article.

Mesoporous silica nanoparticles with varied morphologies and pore structures were synthesized on the kilogram scale using cetyltrimethylammonium bromide and an anionic surfactant as co-templates.

Purpose This study examines the potential of foreign business-to-business (B2B) firms to select high-status local partners in emerging markets to achieve positive relationship outcomes. Because a domestic firm’s high status may also promote opportunism, the study also examines if the foreign B2B firms may mitigate such behavior through either or both transaction-specific investments (TSIs) and socialization. Design/methodology/approach The research is conducted via a model that suggests a positive correlation between high local partner status and the focal relationship outcomes and the moderating effects of structural TSIs and social governance systems. The model was developed and empirically tested using data collected from 96 foreign firms operating in China. Findings Using multiple regressions, the findings suggest that foreign B2B firms are likely to achieve more beneficial relationship outcomes with high-status local partners. Standing alone, foreign B2B firms’ TSIs mitigate the positive relationship outcomes, whereas their socialization with the high-status partners enhances the beneficial outcomes. Most importantly, combining socialization with TSIs increases beneficial outcomes. Research limitations/implications This study adds to B2B marketing, status theory and the application of transaction cost economics (TCE) and social exchange theory to foreign-local B2B exchange relationships in emerging markets. The findings confirm the attractiveness of high status in emerging markets by exploring how the selection, formation and chosen B2B governance processes may lead to competing outcomes of opportunism or success. Future research will benefit from simultaneously securing data from both sides of the dyad. Practical implications The paper suggests that foreign B2B firms consider high status as a key criterion in selecting local partners in emerging markets and the importance of managing high-status partners’ potential opportunism by effective governance mechanisms. Originality/value This study is one of the first to apply and explore the workings of status theory in the foreign-local B2B partner selection process and relationship outcomes in emerging markets and thereby contributes to B2B marketing, status theory and both TCE and social exchange theories in the focal foreign-local B2B context.
