Abstract:

Abstract Advanced thermal interface materials (TIMs) are indispensable for work reliability and lifespan assurance of high-power density electronic systems by facilitating timely and effective heat dissipation. A random algorithm consisting of diluting, dropping, and stirring processes is first proposed to simulate microstructures of TIMs with continuous particle size distribution, with an accessible maximum volume fraction of 55 vol%. Then the size polydispersity impact on the thermal performance and the fluidity of TIMs is numerically investigated. Simulation results reveal that as the parti

Abstract:

Control and quantification of particle size distribution is of importance in the application of nanoscale particles. For this reason, polydispersity in particle size has been the focus of many simulations of particle growth, especially for nanoparticles synthesized from aerosols such as fumed silica, titania and alumina. Single-source aerosols typically result in close to a log-normal distribution in size and micrograph evidence generally supports close to spherical particles, making such particles ideal candidates for considerations of polydispersity. Small-angle X-ray scattering (SAXS) is of

Control of thermal transport in colloidal crystals plays an important role in modern technologies. A deeper understanding of the governing heat transport processes in various systems, such as polydisperse colloidal crystals, is required.

The thermal conductivity of model colloidal crystals has been calculated using molecular dynamics simulations.

Abstract Granular soils feature a wide variety of particle sizes and shapes which makes their discrete simulation a laborious task, as the question arises of what particle shapes should be used to model a real geomaterial. This study introduces a method to generate simplified Representative Element Volumes (REVs) of non-spherical particles in the Discrete Element Method (DEM) with reduced particle shape polydispersity, which nevertheless still represent adequately the shear strength of the real material.

Abstract:

The paper deals with a theoretical study of the magnetoviscous effect in polydisperse ferrofluids. A two-fractional model of colloid consisting of relatively large and small particles is studied. The model is based on the idea that the magnetoviscous effect is determined by chain-like aggregates formed by large particles. The effect of the small particle fraction is determined by two factors: (i) the magnetic interaction between large and small particles, which leads to a reduction of the chain length and weakening of the fluid magnetoviscosity, (ii) the steric interaction between small and la

Abstract:

Cinnarizine belongs to the Class II of Biopharmaceutical classification system, and its absorption from the gastrointestinal tract can be limited by various factors, with the most significant contributors being poor aqueous solubility and membrane permeability of the drug molecule, which further affects the oral bioavaibility. Bio nanocomposite is the process of complex formation between drug and polymers/excipients where microwave energy plays a significant role in reducing the particle size of materials. It breaks intermolecular bonding, which further reduces the particle size, enhanced the effective surface area, solubility, and bioavailability. In the present study, an attempt has been made to formulate and characterize the Cinnarizine loaded Bio-nanocomposites consisting of Xanthan and Guar gum for enhanced solubility of Cinnarizine and percentage drug release from nanocomposite that is satisfactory and bioavailability also comparable to better than other marketed formulations of Cinnarizine. The microwave assisted Cinnarizine loaded Xanthan gum-based nanocomposite formulation was shown a higher percentage of yield (80.80±0.8%), higher solubility (0.830±0.008), nano ranged hydrodynamic diameter (169.36 nm with Polydispersity Index 23.6%), zeta potential (34.4 mv). The transmission electron microscopy study of nanocomposite formulation showed crystal shape of Cinnarizine was completely changed in nanocomposite, showing embedded Cinnarizine crystals in the matrix. This In vitro study concluded that the preparation method of bio-nano composite was simple, reproducible, and provides good solubility in alkaline medium and drug content. Thus, Xanthan gum can be considered as an effective carrier for the crystallization of the drug, possessing suitable microstructural properties to prevent recrystallization of the drug.

Abstract:

Extracted lignin as a by-product of pulping and bio-refining processes is the main available bio-phenolic polymer. The structural complexity, polydispersity, and black color of lignin are the main limiting factors for its application. Preparation of lignin with lower structural complexity and polydispersity through lignin fractionation is one of the primary solutions to engineer lignin into a value-added material. Sequential lignin fractionation was developed based on pH reduction from alkaline to acidic using mineral acids and was recently optimized using carbon dioxide as a pH controller. The partial solubility of lignin in organic solvents is another promising method for lignin fractionation. Organic solvents with different polarity and solubility factors are able to fractionate lignin, yielding a more homogeneous chemical structure. As a modification of the lignin fractionation process, the use of solvents, water/organic solvent mixtures, such as alcohols, and acetic acid from room to high temperature has been proposed as a greener method for lignin fractionation. Using membrane technology is another promising method and current results indicate its good potential for lignin recovery and fractionation.

Abstract:

Discrete Element Modelling has been successfully applied in combination with fluid flow solvers (CFD) to tackle important multi-phase process engineering problems. However, until recently most of the DEM-CFD studies have dealt with monodisperse particulate systems. The reason for that is that DEM requires knowledge of the force exerted by the flowing fluid on each particle. While numerous expressions are available for homogenous systems, the presence of size polydispersion or the presence of solids mixtures complicate particle-level formulations of the drag force considerably and a general model is still lacking. In the present contribution a drag force model for polydisperse system is introduced and discussed. The expression was originally proposed in the literature on the basis of lattice-Boltzmann simulation results for flow through random polydisperse systems. However, its theoretical foundations were not fully recognised. The proposed formula requires the introduction of an average diameter, whose definition will be proved to be rigorously derivable provided that appropriate consistency constraints are considered. No other fitting or adjustable parameters are involved. In the case of a binary mixture of differently sized particles the resulting drag force is shown to depend both on size ratio and local volume fraction of the solids. Such precious particle-level information is then shown to be extendable to the macroscopic scale with attractive potentialities. On this basis, solution to the (open) problem of the segregation direction in a gas-fluidized bed of binary solids endowed with contrasting density and size differences will be suggested.

Abstract This paper describes work carried out on the behaviour of model silica particles dispersed in water containing non-adsorbing (carboxymethyl cellulose and polystyrene sulphonate) polymers. The pair potentials of the particles have been calculated using current quantitative models of depletion flocculation and DLVO theory, with the depth of the secondary minima in the energy curves being used as an index for the onset of flocculation. The depletion flocculation of the particles by polystyrene sulphonate shows excellent agreement between theory and experimental observations, but this was not the case for carboxymethyl cellulose. The discrepancies between theory and experiment may be explained in terms of the high polydispersi!Y of the carboxymetbyl cellulose samples, particularly with respect to the charge distribution as a function of chain length.

The obtained results suggest that the EE is high (80.6±3.3%). The particle size and PDI results indicated the existence of the multil

Abstract:

Infrared radiation heating is a heat pre-treatment method that employs infrared electromagnetic radiation to generate heat in pulses such as cowpea for the production of instantized ingredients and products. Optimum processing conditions, moisture content of 45%, the heating temperature of 185 „ƒ, and time of 5 min was reported to precooked cowpea from previous studies. Modified protein isolates are suitable for industrial use due to their improved functionality. In this study, the effect of optimised conditions (45% moisture, the heating temperature of 185 „ƒ, and heating time of 5 min) on th

Abstract:

Nano-particle image velocimetry (nPIV) uses evanescent waves generated by total internal reflection at a glass-water interface to illuminate fluorescent colloidal tracers and measure the two velocity components parallel to the wall. For blue light at 488 nm, the exponential decay in the intensity of the illumination with distance normal to the wall z ensures that only about the first 300 nm next to the wall are imaged. The exponential decay also suggests that illuminated tracers in nPIV that are closer to the wall have images that are brighter than those farther from the wall. This variation i
