This study investigated the morphological and mineral features of nano zero-valent (nZVI)-induced iron precipitation on quartz particles. Lead was employed as artificial contaminant, while used to mimic inert solid particles in soil. The characterisation indicate that minerals precipitated heterogeneously surface with plush-like flake-like structures. They are made deuterogenic plumbiferous fer...

This poster describes an application under development that supports quantitative analysis of 3D models of stone tools. The models are created from original artifacts by using a laser scanner. The application currently supports interactive labeling of flake scars on flint cores. We discuss our ideas for automatic labeling and future enhancements to the application.

We report the colloidal synthesis of 2D SnTe nanosheets through precursor hot injection in a nonpolar solvent. During reaction, an important intermediate─Sn-template─is formed which defines confined growth SnTe. This “flake-like” structure gives first evidence for possible morphology formation prior to anion (TOP-Te). Additionally, we explore role each ligand reaction process. Thus, explain and...

Exfoliated monolayer graphene flakes were embedded in a polymer matrix and loaded under axial compression. By monitoring the shifts of the 2D Raman phonons of rectangular flakes of various sizes under load, the critical strain to failure was determined. Prior to loading care was taken for the examined area of the flake to be free of residual stresses. The critical strain values for first failur...

The internal lateral ligament is the ligament most frequently damaged. Usually a few of the upper fibres are torn away from the periosteal attachment at the lower end of the femur. Occasionally, however, the deep fibres which are attached to the internal semilunar cartilage are partially torn without the cartilage being damaged. Occasionally, the external lateral ligament is injured. With more ...

This work reports on recent advances in the deposition of non-wettable coatings with high water contact angles (WCAs). We propose a simple and easily-controlled method for fabricating different types of nanoestructured films of Al2O3 with hydrophobic properties by Physical Vapour Deposition (PVD). The films have been deposited over three types of hydrophilic substrates with very different value...

Themechanical behaviorof grapheneflakesunderboth tension and compression is examined using a cantilever-beam arrangement. Twodifferent sets of samples are employed.One consists of flakes just supported on a plastic bar. The other consists of flakesembeddedwithin theplastic substrate.Bymonitoring the shift of the 2DRaman linewith strain, information on the stress transfer efficiency as a functio...

M. Górny, R. Dańko, M. Holtzer. AGH University of Science and Technology, Faculty of Foundry Engineering, Kraków, Poland This article addresses the effect of mold filling and wall thickness on the flake graphite layer in ductile iron. The research was conducted for castings with different wall thickness (3-8 mm) and using molding sand with furan resin. A thermal analysis has been performed alon...
