Collaborative Publishing

In 2012, John Stewart contributed a book manuscript entitled “ Questioning Life and Cognition: Some Foundational Issues in the Paradigm of Enaction” to the Enaction Series in Online Collaborative Publishing, edited by Olivier Gapenne and Bruno Bachimont. Along with Mattéo Mossio, I was invited by Olivier to serve as a glossator of this text. The purpose was to thereby continue our long and fruitful dialogues with John that began when we were both students. I took advantage of the opportunity to also express my gratitude to John for his participation in that formative stage of my personal academic journey. My reflections were included as an epilogue to his book. In memoriam, the epilogue is reproduced in this report unchanged. I will always be grateful to John for making the research community of enaction feel like family to me and for helping me recognize that there is a place for my diverse interests in the continued pursuit of an academic career.

Professor Orlando Zelaya Angel was an outstanding member of the research community on Solid State Physics. He served as President to the Sociedad Mexicana de Ciencia de Superficies y Vacío (SMCSyV; currently Sociedad Mexicana de Ciencia y Tecnología de Superficies y Materiales – SMCTSM), for the period 1995-1996. Professor Zelaya formed many researchers in Mexico, who continue developing research, either in Mexico, in their countries of origin, or abroad. Throughout the evolution of Superficies y Vacío, Professor Zelaya, contributed with sixteen articles on subjects ranging from thin films for optoelectronic applications, through hard coatings and studies on the process for production of Tortillas; covering most of his research areas of interest. Here is a subject-chronological compilation of the abstracts to his articles in Superficies y Vacío, after a year of his departure.

Materials Research

High voltage TEMs were introduced commercially thirty years ago, with the installations of 500 kV Hitachi instruments at the Universities of Nogoya and Tokyo. Since that time a total of 51 commercial instruments, having maximum accelerating potentials of 0.5-3.5 MV, have been delivered. Prices have gone from about a dollar per volt for the early instruments to roughly twenty dollars per volt today, which is not so unreasonable considerinp inflation and vastly improved electronics and other improvements. The most expensive HVEM (the 3.5 MV instrument at Osaka University) cost about 5 percent of the construction cost of the USA's latest synchrotron.Table 1 briefly traces the development of HVEM in this country for the materials sciences. There are now only three available instruments at two sites: the 1.2 MeV HVEM at Argonne National Lab, and 1.0 and 1.5 MeV instruments at Lawrence Berkeley National Lab. Fortunately, both sites are user facilities funded by DOE for the materials research community.
