An alternative to the traditional strategy of developing catalysts with a single metal center is the combined use of more than one metal complex and the design of their cooperative action to achieve new synthetic transformations. With the rich chemistry of metal catalysis that has been developed over the last five decades, as well as recent advancements in organocatalysis and emerging photoredox catalysis, one can imagine that cooperativity of these known catalytic approaches could enable novel synthetic transformations that have been highly challenging via conventional single-site metal catalysis.","PeriodicalId":272074,"journal":{"name":"AsiaChem Magazine","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125213070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We first met in 1977 at Columbia University when he had just started his postdoctoral research with Gilbert Stork, and I was on my way to Madison, Wisconsin, to begin my postdoctoral research with Barry M. Trost. Over the following 44 years, we have had many opportunities to meet in various countries. I have always enjoyed Eiichi’s original science and Baroque flute music. He and his wife Yoko Nakamura visited my family at our home in Israel, and I had a chance to spend time in their beautiful home in Tokyo. Hence, I found it peculiar to conduct a friendly conversation over Zoom. But electronic communication has become an integral part of our life during the Covid-19 pandemic. It was a relaxed weekend in late October 2021, early morning in Israel and afternoon in Tokyo. It was as close as possible to a face-to-face meeting, spending a couple of hours together while staying in our home offices.","PeriodicalId":272074,"journal":{"name":"AsiaChem Magazine","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122370808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Just over ten years ago, the United Kingdom’s Royal Society and the American Association for the Advancement of Science met to clarify what is meant by this term, science diplomacy, and to stimulate further study and analysis. They proposed a schema identifying three aspects of science diplomacy. Despite being criticised by scholars in Europe through the recent European Union project on science diplomacy4, the taxonomy proposed by the Royal Society and AAAS is widely used. The three aspects are science in diplomacy, science for diplomacy, and diplomacy for science. This classification into three separate types of science diplomacy is inevitably imperfect since many activities in science diplomacy are complex and stretch across these three classifications.","PeriodicalId":272074,"journal":{"name":"AsiaChem Magazine","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125419607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This approach avoids the evolution of a potentially explosive H2/O2 gas mixture together with the development of a gas separation facility required to capture H2 from the mixture. We are thus attempting to develop a two-electrode system for solar-light water splitting with the anode only subjected for photo-driven water oxidation to uptake electrons and protons, as nature does. Our target device converts the electrons transferred to the cathode directly to H2 without light illumination, as is the case for the Calvin cycle where CO2 is converted into glucose as a dark reaction. An outstanding feature also lies in the high specific surface areas of both electrodes due to the mesoporous nature of the TiO2 films adopted as the electrode materials.","PeriodicalId":272074,"journal":{"name":"AsiaChem Magazine","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125922571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Meiji Restoration in 1868 is often credited as the starting point of Japan’s introduction to Western science. In fact, Japanese encounters with chemistry started earlier, in the early nineteenth century during the Tokugawa period (1603-1868). Medical doctors took the lead in the reception of chemistry because of their interest in the medicinal properties of chemicals. The development of manufacturing and military industries such as mining and smelting, pottery, brewing, dyeing, photography, and gunpowder manufacturing further stimulated Japanese interest in chemistry. Historical developments of chemistry in Japan thus reflected the process of Japanese modernization and industrialization that eventually led to its prosperity in the twentieth century.","PeriodicalId":272074,"journal":{"name":"AsiaChem Magazine","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116785388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
