REMARKS
-
This page presents a list of publications, presentations, and awards of not only those of Masato Yoshiya's Research Group (Computational Materials Desigining & Creation Lab.) but also those of Tomoya Nagira's Research. This is because it is practically impossible to uniquely divide those into the two, since
- there is practically no boundary or barrier between the two groups,
- all the faculties and students in the two groups conduct their researches aiming at interacting each other whichever group he/she belongs to, with the most focus on his/her expertise, but not confined to his/her current own expertise, through supplementing what is foreign to him/her each other, thereby extending the field of his/her expertise.
Therefore, contents of this page include those prior to Masato Yoshiya's joining to Osaka University and those since the foundation of Hideyuki Yasuda's Research Group (Materials Process & Design Creation Lab.) on April, 2004.
- Links to the papers of which Masato Yoshiya is a coauthor and which is available on the Internet through DOI server are provided at Masato Yoshiya's personal page. You can obtain an electronical copy of the papers through the links at Masato Yoshiya's personal page. In addition, they are available through other authors's personal webpages.
- Although maximal efforts have been made to the accuracy of this page, there may be a mistake or more in the record since this page is based on the record compiled at a Wiki page of the two groups' internal web site, to which the each corresponding author records his/her is primarily responsible for. If you find something wrong, we will highly appreciate if you notify us. Please let Masato Yoshiya know if he is one of the coauthors. If not, please contact the corresponding author of the paper.
- Many of records of Oral/Poster Presentations in domestic conferences in Japan and papers written in Japanese are excluded from the page in English. Please refer to the page in Japanese for completeness.
- For further details, please contact corresponding authors of papers and presentation.
