WebbMentioning: 2 - Optical trapping at an interface mediates the gathering and assembling of particles, inducing the so-called optically evolved assembly that can expand outside the laser focus due to multiple scattering processes. In previous studies, we reported that the so-called Au nanoparticle (NP) dynamically evolving assembly has a dumbbell shape, in … Shape factors are dimensionless quantities used in image analysis and microscopy that numerically describe the shape of a particle, independent of its size. Shape factors are calculated from measured dimensions, such as diameter, chord lengths, area, perimeter, centroid, moments, etc. The dimensions of the … Visa mer The most common shape factor is the aspect ratio, a function of the largest diameter and the smallest diameter orthogonal to it: $${\displaystyle A_{R}={\frac {d_{\min }}{d_{\max }}}}$$ Visa mer The compactness shape factor is a function of the polar second moment in of a particle and a circle of equal area A. $${\displaystyle f_{\text{comp}}={\frac {A^{2}}{2\pi {\sqrt {{i_{1}}^{2}+{i_{2}}^{2}}}}}}$$ The fcomp of a circle … Visa mer Greenland, the largest island in the world, has an area of 2,166,086 km ; a coastline (perimeter) of 39,330 km; a north–south length of 2670 km; and an east–west length of 1290 km. … Visa mer Another very common shape factor is the circularity (or isoperimetric quotient), a function of the perimeter P and the area A: Visa mer The less-common elongation shape factor is defined as the square root of the ratio of the two second moments in of the particle around its principal axes. $${\displaystyle f_{\text{elong}}={\sqrt {\frac {i_{2}}{i_{1}}}}}$$ Visa mer The waviness shape factor of the perimeter is a function of the convex portion Pcvx of the perimeter to the total. $${\displaystyle f_{\text{wav}}={\frac {P_{\text{cvx}}}{P}}}$$ Some properties of metals and ceramics, such as Visa mer • J.C.
