About 40 years ago, I had written two papers about the bubble column for the Journal of Kagaku Kogaku (the Journal of Chemical Engineering, Japan). The first one of two papers was cited sometimes by some authors on the Kagaku Kogaku. After a few years, the first paper was recorded on the electronic version of the Chemical Abstracts. The electronic version was accessible by using the exclusive telephone line in those days.Recently I heard that the papers on science and technology were easily able to be got on the Internet. I thought that If things went well, I could find my papers on the Internet. At once I tried to inputting the various keywords, which I remembered about the papers, at Google site. Unfortunately I could not find mine. But I found some authors were citing my paper when I inputted bubble, columns, particles, and my family name as the keywords.
Surprisingly one of my papers was cited on the Bulletin of Beijing University of Chemical Technology, and a review of International Journal of Chemical Reactor Engineering (vol.2 (2004)). The home page of the Bulletin showed the literature cited by the Bulletin, but the contents of the Bulletin itself was not accessible. The home page of the review that was titled "Phase Mixing Modeling in Multiphase Reactors Containing Gas Bubble" contained its contents and summary, and showed the cited literature.
I am satisfied with the fact that my paper that was written about 40 years ago is being now criticized on the Internet.
This internet search reminded me of many incidents of those days, and I was difficult to fall asleep for a few days. When a carton of soybean paste called kinzanji-miso was gifted by the head of my neighborhood association as the celebration of 75 years old, I was returned perfectly to the Respect-for-the-Aged Day of the year of 2006 from the time travel. I fall asleep now as usual. (As a matter of fact, I do not fall asleep so easily by nature.) I like better today's stressless life than the life of 40 years ago.
Bubble column: A tube is stood up vertically, and filled with liquid. Then gas is blown into the liquid from the bottom, and liquid is supplied continuously to the tube or not supplied. This state of the tube is called the bubble column.
The bubble column is often used for the gas absorber and gas-liquid reactor. Catalytic particles are suspended sometimes in the bubble column to prompt the chemical reaction. My model indicated the gradient of the particle concentration in the bubble column.
Chemical Abstracts (published by the American Chemical Society): This magazine records author names, titles, summaries, and journal names of the chemical papers in the world. I suppose it was published weekly.
