An Innovative Non-contact Method to Determine Surface Free Energy on Micro-areas

Surface free energy (SFE) is a property which depends on the chemical state and roughness of the surface and it is necessary to develop a reliable method to evaluate SFE value on a small area, taking into account these two different contributions. Today contact angle methods are the most used and they allow to evaluate …

Focus on Microscopy 2014 – Abstracts of the Presentations Online Available

“This was the third time the FOM meeting had been held in Sydney”, commented Guy Cox, Honorary Associate Professor, School of Medical Sciences, Sydney, Australia  and local co-organizers for FOM. “Family problems, and airline strikes, forced some invited speakers to withdraw, but we still had a stellar cast of international speakers, and a keen crowd …

Surface Roughness of Flowable Resin Composites eroded by Acidic and Alcoholic Drinks

Acidic beverages, such as soft drinks (orange juice, and cola), or ethanol (whisky), can produce erosion of resin composites. The surface degradation of resin materials is related to the content and distribution of the fillers, the composition of the matrix resin, and the effect of silane surface treatment on the fillers. Direct Class II composite …

Fully Automated Tracking of Chloroplasts in Elodea Leaf Cells from 4D Image Data

Fully automated tracking of moving 3D structures in living cells represents several challenges that are typical to the analysis of biological image data. Taking 4D image data from chloroplasts in living Elodea leaf cells as an example we demonstrate new approaches to meet these challenges (Figure 1). Chloroplasts are surprisingly dynamic organelles: They move extensively throughout …
