The effect of settling on cytotoxicity evaluation of SiO2 nanoparticles
Anastasia Spyrogianni,Georgios A. Sotiriou,Georgios A. Sotiriou,Davide Brambilla,Jean-Christophe Leroux,Sotiris E. Pratsinis +5 more
TL;DR: In this article, the authors evaluate quantitatively the importance of nanoparticle settling for the in vitro cytotoxicity evaluation of aerosol-made, fractal-like SiO 2 nanoparticles that have similar agglomerate size and structure but varying primary particle diameter.

Synthesis and characterization of polyaniline–Fe@C magnetic nanocomposite powder
C.T. Fleaca,Florian Dumitrache,I. Morjan,A.-M. Niculescu,I. Sandu,Alina Ilie,Ioan Stamatin,A. Iordache,Eugeniu Vasile,G. Prodan +9 more
TL;DR: In this article, the synthesis of novel magnetic nanocomposite based on polyaniline (PANI) matrix and Fe-C nanoparticles was reported, and the structure of the resulting composite was characterized by Transmission Electron Microscopy, X-ray diffraction and also by Raman and infrared spectroscopy.

The influence of tungsten carbide contamination from the milling process on PCD materials oxidation
Lucyna Jaworska,Anita Olszówka-Myalska,Sławomir Cygan,Pawel Figiel,Małgorzata Karolus,Jolanta Cyboroń +5 more
TL;DR: In this article, the influence of mixture preparation on the microstructures and selected properties of polycrystalline diamond compacts has been investigated using X-ray diffraction analysis, and the results showed that the incorporation of nanoparticles between diamond microsize particles limits the residual porosity and improves the roughness properties of cutting tools.

Numerical Study of the Agglomerates Dispersion Behavior in Shear and Elongational Flow Fields in Viscous Media Using Population Balance Modeling (PBM)
TL;DR: In this paper, the dispersion of the agglomerates was studied in shear flow fields (SFF) and elongational flow field (EFF) using population balance method, and a power-law break-up kernel was proposed for EFF and an exponential one was considered for SFF.
Journal ArticleDOI
Evaluating the use of zinc oxide and titanium dioxide nanoparticles in a metalworking fluid from a toxicological perspective
TL;DR: In this paper, the authors investigated the potential environmental and human health effects of nano-enabled products during early design and development, and found that the addition of these NPs increased toxicity relative to the NP-free formulation.

Collapse of an initially spherical vapour cavity in the neighbourhood of a solid boundary
TL;DR: In this paper, a numerical method was proposed to solve the problem of balloon bubble collapse near a plane solid wall, using finite time steps and an iterative technique for applying the boundary conditions at infinity directly to the liquid at a finite distance from the free surface.

Cavitation produced by Ultrasonics
B E Noltingk,E A Neppiras +1 more
TL;DR: In this article, the problem of cavitation produced by ultrasonic vibration is examined theoretically, and it is predicted that all cavitation phenomena will diminish and finally disappear as the frequency is raised.

Agglomerate and Particle Size Effects on Sintering Yttria‐Stabilized Zirconia
TL;DR: In this article, the initial-, intermediate-, and final-stage sintering of fine crystallite yttria-stabilized zirconia was studied, and it was found that agglomerates limit attainable green density, interfere with the development of microstructure, impede initial-stage Sintering kinetics, and limit the potential benefit of the fine crystallites on final stage sinterings.
