These comprise: (1) The infinitesimal columns model (IC), (2) Shard’s empirical formula (TNP-model) and (3) SESSA (Simulation of Electron Spectra for Surface Analysis) simulations with and (4) without elastic scattering. Experimental data on of a round robin experiment of PMMA@PTFE CSNPs were analysed with the aforementioned approaches and show a good mutual consistency and agree with the nominal shell thickness. However, use of the F1s signal leads to significant deviations. Transmission Electron Microscopy measurements revealed that the core-shell structure is non-ideal, i.e. the particles are aspherical and the cores are acentric within the particles. SESSA simulations were employed to estimate the effect of various types of deviations of ideal NPs on the outcome of shell thickness determination. The usefulness and importance of different kind of electron beam techniques for CSNP analysis and in particular shell thickness determination is discussed.","PeriodicalId":90628,"journal":{"name":"Journal of surface analysis (Online)","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66653294","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}

As a result, fragmentation-free spectra from surfaces composed of or covered with complex molecules such as peptides and proteins are observed.

In order to evaluate the impact of BC on human health, it is necessary to observe the detailed structure of BC along with toxicology. Focused ion beam time-of-flight secondary ion mass spectrometer (FIB-TOF-SIMS) developed by the authors, has a high spatial resolution and low detection limit, and the components imaging of individual particle can be analyzed with many kinds of aerosol. However, since BC is very small, the detailed structure of particles cannot be observed directly with the FIB-TOF-SIMS. In this study, in order to evaluate the structure of BC, we combined a new aerosol dialysis method and the FIB-TOF-SIMS. In this method, even if the lateral resolution is insufficient, the structure of BC can be visualized with separating the particles and surface adhering components, respectively.","PeriodicalId":90628,"journal":{"name":"Journal of surface analysis (Online)","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66654284","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}

With this method, the reduction of the ring formation was observed by a freeze-drying specimen preparation.
