Because of their universal physical properties, such as the size distribution, mass fractal dimension, and viscoelastic properties, these clusters have drawn the great attention of many physicists. This review briefly introduces a few recent remarkable experimental results, which shed light on remaining questions of the critical clusters. The static structure and dynamics of these critical clusters were investigated using small angle neutron scattering (SANS), static light scattering (SLS), and dynamic light scattering (DLS). The reviewed studies primarily focused on the data analysis for the critical clusters in the intermediate concentrations between dilute and semidilute limits. An intermediate model developed by Bastide and Candau well ex-plained the observed static scattering profiles, indicating a coexisting state of the dilute and semidilute solutions. The dilute and semidilute features were also observed in dynamic studies as a superimposed translational motion of small dilute clusters and cooperatively diffusion of large semidilute clusters. These fundamental understanding may contribute to the applications of the critical clusters and further studies for the percolation process.","PeriodicalId":19282,"journal":{"name":"Nihon Reoroji Gakkaishi","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2022-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44028646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"49 Volumes of Nihon Reoroji Gakkaishi (the Journal of the Society of Rheology, Japan)","authors":"Y. Masubuchi","doi":"10.1678/rheology.50.147","DOIUrl":"https://doi.org/10.1678/rheology.50.147","url":null,"abstract":"Nihon Reoroji Gakkaishi, the Journal of the Society of Rheology, Japan, has reached the milestone, the 50 th volume. We wish to rejoice with all the current and past members of the society in this memorable event. The first issue of our journal appeared in 1973 in conjunction with the founding of the society. In the greeting for the first issue, Professor Masao Horio , the founding president, expressed his pleasure at the launch of the journal. He described the role that the journal should play: to disseminate Japanese rheological research both domestically and internationally, introduce the situation overseas to the members, and enlighten knowledge through review articles and commentaries. These missions naturally came from the success of the 5 th International Congress on Rheology in Kyoto. (Remarkably, the Japanese rheologists organized the event before the foundation of the Japanese Society of Rheology.) Although the second one has been somewhat diminishing in recent years with the development of the internet and online publishing, the missions have been fulfilled by significant efforts by society members. In this article, let us retrospect the journal’s history according to some records to express our respect for the accumulated contributions. In our journal, we combine the bulletin and the scientific articles, and the latter part is available on-line . As seen in the table of contents on the web, one volume has been published each year, and each volume contains four issues before volume 30. The later volumes consist of 5 issues with a few exceptions. The total number of published articles is more than 1500 in 210 issues up to the volume 49, as seen in Fig. 1. However, only a part of the accumulated papers is listed in the scholarly article databases like Web of Science (WOS) and Scopus. For instance, in WOS, we can find less than 900 papers from our journal. The main reason of the discrepancy between the number of published papers and the number of listed papers in the database is that the databases are not complete, and they are still working to accommodate old documents. Apart from this external one, we have two issues: the journal name and the writing language of published papers. Concerning the journal name, “Nihon Reoroji Gakkaishi (日本レオロジー学会誌)” is unmistakable for Japanese speakers, meaning the Journal of the Society of Rheology, Japan. However, the spelling would be somewhat complicated for people who are not familiar with the Japanese language. Indeed, in the database, we can find some variations like Reoroji Aakkai, Reoroji Bakkai, Reoroji Gskkai, Reoroji Kakkai, etc. Besides, around 100 papers are seen in the database with the journal name in English: Journal of the Society of Rheology Japan. The citations with these variations are not correctly accumulated.

The peak position and peak area of each Raman band are influenced by microscopic deformations of molecular chain e.g. load-sharing, orientation, and conformational state. In particular, Raman spectroscopic analysis has been used to investigate the structure–mechanical properties relationship of semi-crystalline polyolefins (POs) because the C–C stretching mode, which is the main chain vibration of POs, is strongly Raman-active. The present review summarizes recent Raman spectroscopic analyses of the structure–mechanical properties relationship of POs.","PeriodicalId":19282,"journal":{"name":"Nihon Reoroji Gakkaishi","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2022-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43691371","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SMFS is used to obtain static information about single polymer chains, mainly through a quasistatic stretching process. With technological developments in recent years, dynamic SMFS measurements under nonequilibrium conditions have also been realized. The dynamic viscoelasticity of single molecule chains can also be measured, which will benefit our understanding of the nonequilibrium dynamic properties of polymeric materials.","PeriodicalId":19282,"journal":{"name":"Nihon Reoroji Gakkaishi","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2022-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42882528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In synthetic processes, the elastomers possess a heterogeneous network structure, which affects the rheological behaviors of elastomers, such as rubber elasticity. Although the heterogeneous structure of elastomers has been evaluated using both experimental and simulation methods, it is still difficult to estimate the heterogeneous structure of elastomers in terms of connectivity. Recently, the author reported a novel evaluation method for the chain connectivity of elastomers based on network theory to describe rubber elasticity. The unified centrality, including both topological and spatial information, can describe certain parameters related to rubber elasticity. Furthermore, the behavior of extended chains is also described by centrality. This approach is expected to contribute to progress in the theory of rubber elasticity by considering complex connectivity.","PeriodicalId":19282,"journal":{"name":"Nihon Reoroji Gakkaishi","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2022-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44213127","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
