• An efficient geometric method better calculates preferential concentration of particles. A contractivity-preserving splitting preserves the sum Lyapunov spectrum. The centrifuge effect is also mimicked in numerical solution. Non-divergence-free interpolation can erroneously cluster Matrix-valued RBFs are equivalent to via regularized Stokeslets. for simulating suspensions spherical and non-sp...

Spherical particles of mesoporous silica SBA-16 with cubic Im3m structure were synthesized at low pH using Pluronic F127 as template and TEOS as silica source. The diameter of the spherical particles can be controlled in the range of 0.5–8 μm by varying{Spherical particles of mesoporous silica SBA-16 with cubic Im3m structure were synthesized at low pH using Pluronic F127 as template and TEOS a...

Spherical crystallization of drugs is the process of obtaining larger particles by agglomeration during crystallization. The most common techniques used to obtain such particles are spherical agglomeration and quasi-emulsion solvent diffusion. Ammonia diffusion systems and crystallo-co-agglomeration are extensions of these techniques. By controlling process parameters during crystallization, su...

Twisted light carrying orbital angular momentum inherently possesses a handedness, which would produce chiroptical responses by chiral matter. In this work, scheme of vortical differential scattering (VDS) was utilized to investigate the dielectric particles twisted light. The simulation results showed that have obvious VDS signals under illumination with opposite topological charges. larger re...

Sucrose density gradient analyses of pH 5.5 and pH 7.4 extracts from rat liver nucleoli revealed the presence of two broad peaks of approximately 60S and 80S, and 60S and 80-100S, respectively. Ribonucleoprotein (RNP) particles containing precursor ribosomal RNA in these peaks have been characterized by electron microscopy and RNA analyses. Spherical particles only were found in the 60S peak of...

Fluidization of non-spherical particles is a common process in energy industries and chemical engineering. Understanding the fluidization important to guide relevant processes. There already have been numerous studies which investigate behaviors different during fluidization, but investigations polyhedral do not receive much attention. In this study, investigation described by polyhedron approa...

We present a new linearization of T-Matrix and Mie computations for light scattering by non-spherical and spherical particles, respectively. In addition to the usual extinction and scattering cross-sections and the scattering matrix outputs, the linearized models will generate analytical derivatives of these optical properties with respect to the real and imaginary parts of the particle refract...
