Abstract:

Great attention has been given to the synthesis of monodispersed and uniform colloidal polymer particles with controllable particle sizes. However, investigations on the preparation, characterization and fabrication of polydisperse polymeric particles are very few. Polydisperse polymers are also needed to meet the new demands of the modern markets due to the ease of their synthesis. This study, therefore, synthesized polydispersed poly(styrene-methyl-methacrylate acrylic-acid) (P(St-MMA-AA)) via emulsion polymerization synthetic approach under unstable reaction conditions. The synthesized P(St

Abstract:

In recent years an indubitable progress has been made in the development of separators for powder fractionating. The development of new types of cascade separators significantly improves the quality of final fractionation products. Consumed material concentration in all types of cascade separators does not exceed, as a rule, two kilograms of solid phase per a cubic meter of air flow. Therefore, to attain high productivities, considerable investments are needed, because for this purpose several apparatuses operating in parallel or apparatuses of large overall sizes are required.

Abstract:

Sound absorption of polydisperse heterogeneous porous composites is investigated in this paper. The wave equation in polydisperse heterogeneous porous composites is upscaled by using the two-scale method of homogenisation, which allows the material to be modeled as an equivalent fluid with atypical effective parameters. This upscaled model is numerically validated and demonstrates that the dissipation of sound in polydisperse heterogeneous porous composites is due to visco-thermal dissipation in the composite constituents and multiple pressure diffusion in the polydisperse heterogeneous inclus

Abstract:

The effect of polydispersity of nickel-silver core-shell nanoparticles (Ni-Ag NPs) on the conductivity of ink coatings was studied. Ni-Ag NPs of various average diameters (100, 220, and 420 nm) were synthesized and utilized for the preparation of conductive inks composed of monodisperse NPs and their polydisperse mixtures. The shell thickness of synthesized Ni-Ag NPs was found to be in the range of 10–20 nm and to provide stability of a core metal to oxidation for at least 6 months. The conductivity of metallic films formed by inks with monodisperse Ni-Ag NPs was compared with those formed by

Abstract:

The key factors for reflection loss of porous materials were studied mainly through experimentation. Regarded aggregate particles as polydisperse particles in porous concrete, by introducing Mie solution on scattering by a spherical particle, and combining with independent scattering discipline for polydisperse particles, a theoretical method for calculating microwave absorbing properties of porous concrete with aggregate diameter in logarithm normal distribution is presented, which can forecast the absorption properties of porous concrete preferably.

The article deals with theoretical and experimental studies of the compaction processes of various types of powdered polydisperse materials for the study of kinematic, design-technological and energy-power parameters of units. The basic laws of briquetting in press-roll units and the need for their constructive and technological implementation have been established. The calculation of the main energy-power parameters of the equipment for briquetting (pressing force; power expended by the roller and jaw pre-compactors; total power consumed by the roller press) is presented.

Numerous flexible homopolymers and flexible random copolymers are commercially available. Thus, understandably, a number of research groups have reported on the rheological behavior of flexible homopolymers and flexible random copolymers in the bulk and solution states. There are too many studies to cite them all here. In Chapters 3 to 5 we presented the rheological behavior, in general terms, of linear flexible homopolymers in steady-state shear flow, elongational flow, and/or oscillatory shear flow.

Thermal interface materials (TIMs), which transmit heat from semiconductor chips, are indispensable in today’s microelectronic devices. Designing superior TIMs for increasingly demanding integration requirements, especially for server-level hardware with high power density chips, remains a particularly coveted yet challenging objective. This is because achieving desired degrees of thermal-mechanical attributes (e.g. high thermal conductivity, low elastic modulus, low viscosity) poses contradictory challenges. For instance, embedding thermally conductive fillers (e.g. metallic particles) into a
