纳米二氧化钛光催化降解罗丹明6G的应用研究

采用醇盐水解法制备纳米二氧化钛,最佳制备条件为醇：酯：蒸馏水=1：1：10（体积比）;搅拌时间1h;煅烧温度为500℃;煅烧时间为2h。制得的纳米TiO2为单一晶型即锐钛矿型,平均粒径为17．32nm,比表面积为73．683m^2／g。光催化降解罗丹明6G的最佳操作条件是：TiO2用量0．5g;0．594％的H2O2溶液5mL;1．05％的FeCl3溶液1．5mL;反应时间为30min。脱色率达到98．51％。由于H2O2和FeCl3的协同作用,缩短了反应时间,提高了光催化效率。

Moderating effects of the fit between service tangibilization and organizational performance

As the significance of service industry grows, its relationship to overall economic growth and organizational performance (OP) has also become an issue of prominence. Tangibilization is widely known as one of the means of overcoming the weaknesses of service intangibility and improving OP. This research explores the relationship between service tangibilization and OP. Furthermore, the moderating effect of the fit between service tangibilization and OP will also be discussed in the business context. Specifically, the Korean natural gas industry is selected to test the developed hypotheses. The managers who have experience with managing a service business in either the wholesale or retail sector of this industry were surveyed. The results imply that there exists a significant relationship between service tangibilization and OP, with the mental fit positively strengthening some of the relationships between these two constructs. It can be inferred from this that it is important for companies in the natural gas industry to attain the right fit of mental tangibilization in order to effectively deploy service tangibilization and maximize their OP.     

Perceived resource deficiency and internationalization of small- and medium-sized firms

It is documented in the literature that resource deficiency constitutes a barrier to firms’ internationalization. However, small- and medium-sized firms' (SMEs) perceptual barriers to internationalization have received little attention. By highlighting the importance of managerial perceptions in strategic decisions and integrating the resource-based view and the technology acceptance model, this study examines the role of perceived resource deficiency in SMEs’ internationalization. The major finding of this study suggests that perceived resource deficiency in knowledge-based resources constitutes a major perceptual barrier to SMEs’ internationalization. Particularly, perceived resource deficiency in knowledge-based resources has more negative impact on internationalization than does that in other firm-specific resources.
