Residents who dare to go outside cover their mouths and noses with scarves or surgical masks, but their eyes tear up and their throats sting from the mist of pollutants, which a report by the municipality of Tehran says is made up of a mixture of particles containing lead, sulfur dioxide and benzene.
The pure FePt film showed a continuous microstructure, while the Cu-doped FePt films showed a mixture of particle-like and continuous microstructures.
Dynamic light scattering technique demonstrates that homoeopathic tincture is a mixture of particles varying from micron to nanometre sizes.
As shown in Figure 3, for a mixture of particles with obvious size difference (bimodal distribution), the calculated Z-average carries irrelevant size information.
A general equation is proposed for predicting the minimum fluidisation velocity of a mixture of particles of various sizes but all of the same shape and density.
We show the feasibility to fractionate a mixture of particles for systems in which partition is induced via 1-g gravity and Van der Waals interactions in physically or chemically patterned channels.
Porous media were composed by particles of sugarcane bagasse (SCB) and by a mixture of particles of SCB, orange pulp and peel (OPP) and wheat bran (WB) at proportion SCB OPP:WB 1 2 2 w/w (composed medium), agricultural waste used as substrates in bioreactors of solid-state fermentation (SSF), an interesting biotechnological application of PBs.
It is not currently possible to distinguish between NPs, aggregates of the same compounds, and aggregates of a mixture of particles, dust, and other airborne particle types.
From this and other work, it has been shown that the specific surface area of a mixture of particles is inversely proportional to the average diameter of the particles.
These data should be kept in mind regarding the high incidence of radiolucent lines found in recently published medium-term results of clinical trials with impaction grafting with a mixture of bioceramic particles and bone particles (9 of 24 patients) and especially bioceramic particles alone (20 of 37 patients) (Whitehouse et al. 2013a, 2013b).
