In the figure, the particles have charges q1 = -q2 = 200 nC and q3 = -q4 = 98 nC, and distance a = 5.9 cm. What are the (a) x and (b) y components of the net electrostatic force on particle 3?Here’s the best way to so...

aIn Figure 1b, that depicts the SiC nanoparticles, while there seem to be particles on the order of 200 nm across, the all of the particles in the field of view of the micrograph seem to be agglomerated into a single particle. Other nanoparticles obtained from other vendors are often agglo...
Welding fumes induce lung toxicity and are carcinogenic to humans but the molecular mechanisms have yet to be clarified. The aim of this study was to evaluate the toxicity of stainless and mild steel particles generated via gas–metal arc welding using p
Figure 2a shows the uniform distribution of the surface potential for Sample 5 after corona charging. Fig. 1: The proposed spray-coating method for electret material with nanoparticles. a Schematic of the electret material deposited by spray coating and small bubbles and PS nanoparticles are ...
(see Figure 1). The material presents the same random structure and properties as any other glass. The experimental data were produced at the Max Planck Institute in Goettingen (Germany) in the lab of Prof. Peter Keim, and th...
1d. From the figure, it is clear that the graphene oxide sheets obtained by sonication of the graphite oxide are in the form of thin, flexible and wrinkled sheets. The XRD patterns were used to evaluate the oxidation of our samples. Jeong et al. [11] have shown that the XRD pattern ...
Figure 1 shows TEM images of the silica NPs and silica MPs. The appearance of silica NPs and silica MPs was approximately spherical. The size of silica NPs and silica MPs were 25.9 ± 3.4 nm and 1087.8 ± 389.6 nm, respectively. Silica NPs tended to aggregate/agglomerate in deionized water...

(see Fig. 2.2 of Yasutomi32). On this plane, the isotherms move to the high-pressure side as the temperature rises. The intersections of such a large number of different isotherms and a straight line with constant pressurep0(the red horizontal line in the previous figure) give a density-...
