Research trends on minimizing the size of noble metal catalysts for Li-CO2 batteries: From nanoparticle to single atom

노여진,유윤정,류원희 한국화학공학회 2023 Korean Journal of Chemical Engineering Vol.40 No.3

Li-CO2 batteries involve a spontaneous conversion reaction by injecting CO2 into a cathode, and reversibly store energy without additional energy input through a charging and discharging process, thereby achieving carbon neutrality. Noble metal-based electrocatalysts have been actively considered to efficiently facilitate the Li-CO2 reaction with reduced overvoltage, yet the use of expensive noble metal catalysts is a barrier to developing this type of Li-CO2 battery. Here, the importance of minimizing the size of noble metal particle-based catalysts for Li-CO2 batteries is reviewed and emphasized. Comparisons of the performance of Li-CO2 cells with noble metal catalysts, such as Ru and Ir, showed that overpotential is lower when particle sizes are reduced to the single atom-scale. This indicates that the smaller the particle-to-atomic scale, the greater the catalytic activity. Recent diverse studies based on nano- or atomic-scale Ru and Ir catalysts affecting catalytic activities of the Li-CO2 cell reaction are introduced. Other single atom catalyst candidates are also suggested for Li-CO2 battery applications.

The relation of positive illusions and attributional style. Rho, Yeo-Jin Lee, Jee-Yon The relationship between attributional style and positive illusion (self-enhancement bias) was examined. Three hundred twenty eight women university students were questionnaire assessed in their positive illusion, an indication of self-enhancement bias, and their attributional style in several hypothetical situations. The results were as follow. In success situations, those with higher, in contrast with lower positive illusion, showed higher internal attribution. However, in failure situations, the pattern was reversed: their the same internal attributional score was significantly lower than those with low positive illusion. The results showed that people with high positive illusion attempt to maintain their high self-esteem by attributing to self for successes and attributing to externals for failures. 본 연구에서는 자기 고양적 편향과 귀인 양식 간 관련성을 검토하였다. 348명의 여자 대학생들이 긍정적 착각과 성공 혹은 실패 상황에서 귀인 양식을 측정하는 질문지에 응답하였다. 특히 이 연구는 귀인을 측정하는 질문지에 있어서 상황 대본 질문지를 사용하였다는데 그 의의가 있다. 우리나라에서 사용하는 귀인 질문지 대부분이 특정한 상황이 제시되기 보다는 일반적으로 서술된 내용이 제시가 된다. 그러나 이 연구에서는 자신이 처한 특정한 상황을 제시하고 직접 그 원인이 어디에 있는가를 물어봄으로써 머리 속으로만 생각하는 귀인이 아니라 실제 생활 속 여러 사건들에 처했을 때 그 원인을 어디에서 찾는가를 측정, 즉 “상황 특정성 (situation-specificity)"을 고려했기 때문에 연구 대상자들의 귀인 양식을 좀 더 명확하게 측정했다고 할 수 있겠다. 348부의 설문지 중 불성실하게 응답한 20부를 제외한 328부가 분석에 사용되었으며 SPSS (version 12.0) 프로그램이 이용되었다. t-test 결과는 다음과 같다. 첫째, 자기 고양적 편향 수준이 높은 집단이 그렇지 않은 집단에 비해 긍정적 사건에 대한 귀인 양식 점수가 유의미하게 높았다 (t=6.34, df=209, p<.001). 둘째, 자기 고양적 편향 수준이 높은 집단이 그렇지 않은 집단에 비해 부정적 사건에 대한 귀인 양식 점수가 유의미하게 낮았다 (t=-3.68, df=209, p<.001). 즉, 이는 자기 고양적 편향이 높은 사람들은 낮은 사람에 비하여 성공 상황에서는 자기에게 공을 돌리는 내적 귀인을 많이 하였으며 실패 상황에서는 외부로 허물을 돌리는 외적 귀인을 많이 하였음을 보여 준다. 이를 통해 자기 고양적 편향의 정도가 높은 사람은 낮은 사람에 비하여 성공에 대해서는 내적 귀인 실패에 대해서는 외적 귀인을 함으로써 자신의 자아 존중감 (self-esteem)을 유지하고자 한다는 것을 알 수 있다. 이 연구 결과는 상담에서 자아 존중감이 많이 낮아진 채 상담실을 찾는 내담자들에게 그들이 가진 긍정적인 힘을 자각시켜주고 그들 스스로 자신의 자아 존중감을 회복하도록 도와줌으로써 내담자들이 이 상황을 스스로 해결할 수 있으며, 또한 미래를 낙관적으로 보고 희망을 가질 수 있도록 할 수 있다는 것을 보여준다.

This study attempted to investigate customers' risk perception factors and their effects on customer behavior in the selection of hair salon services. For this, data were collected through a questionnaire survey, and a total of 267 copies were used for analysis. Then, SPSS 21.0 was used for a frequency analysis, descriptive statistics, a factor analysis, a reliability analysis, one-way ANOVA and a multiple regression analysis. As a result, the study found the following: First, fewer than half of the customers were satisfied with their current hair salon services, and many of them were not loyal and were willing to switch hair salons if possible. Second, in terms of the risk perception factors in the selection of hair salon services, the following five factors were derived; relation risk, technology risk, price risk, loss risk and follow-up risk. Third, a difference was found between risk perception and customer behavior depending on the level of their satisfaction on hair salon services and the selection criteria for the services. Lastly, it was observed that customers were more likely to change salons when the technology risk was perceived to be high while both switching and continuous behaviors were observed when the price risk was highly recognized.

This paper aims to identify the impact of social commerce service by hair service providers on hair services and so provide basic marketing data for hair service providers in social commerce. The results by empirical analysis are presented below. In accordance with demographic analysis, women used these services more than men. College students ranging in age from 18 to 20 years old showed the highest usage ratio. For average monthly income, singles with an income from 300,000 KRW to 500,000 KRW had the highest ratio. The benefits from social commerce on sub-categories of hair service were analyzed. Four benefits were identified: convenience, economy, reliability and service. The disadvantages of hair service by social commerce were two types--insufficient skills and unkindness--and insufficient post-treatment. For the impact of the benefits from social commerce on hair service, social commerce had a positive impact on insufficient skills and unkindness and also on insufficient post-treatment. However, reliability and diversity showed a negative impact. Since the benefits from social commerce had a significant impact on hair service, social commerce needs to provide a variety of hair services. Hair service providers within social commerce may denigrate their awareness of the services due to excessive competition. These providers must therefore offer a variety of hair services to satisfy potential customers. When they offer a variety of products as more professional service providers and build reliability on service contents as well as convenience of social commerce, the hair service market in social commerce will become more advanced.
