For example, the material for capturing analytes, harmful elements, and biomarkers can be used for pretreatment, decontamination, and diagnosis, respectively. The only difference is the target - capture molecules. A large part of the material design strategy can be common. To effectively and quickly develop novel capturing materials, we utilized radiation - induced graft polymerization by selecting the substrate for grafting from the point of view of chemical engineering, applying the desired graft polymerization, and performing subsequent chemical reactions. In this paper, a novel method for determining the mole percentage of an as - formed polymer brush and root is introduced as a new technique for evaluating grafted materials. In addition, according to the above determination technique, an extractant - impregnated porous sheet for rapid analysis and extractant - impregnated non - porous particle for high - resolution separation of rare earth elements were developed. We also developed metal ferrocyanide - impregnated fi bers for radioactive cesium removal and a surface - functionalized power - free micro fl uidic chip for biomarker detection.","PeriodicalId":17878,"journal":{"name":"Kobunshi Ronbunshu","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81406545","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}

On the other hand, in the case of ultraviolet - irradiated HIPS, the peaks of butadiene monomer and dimer almost disappeared in the pyrogram while the styrene - related peaks were still observed similarly to those for the original HIPS. This fact suggests that the photodegradation of HIPS is mainly caused by the decomposition of polybutadiene components, accompanied by the deterioration, especially of the impact properties. Furthermore, as for the market - recovered HIPS for cover materials, the degree of yellowing ( color di ff erence ¦ E ) of the materials was well correlated with the decrease in the relative peak intensities of butadiene monomer and dimer observed in their pyrograms. This result demonstrates that the degree of photodeterioration of HIPS can be roughly evaluated by Py - GC.","PeriodicalId":17878,"journal":{"name":"Kobunshi Ronbunshu","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77799009","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}
