In this paper we present a method to apply two dimensional textures onto composite and articulated objects defined by implicit functions. The method generates a particle system associated to the gradient vector field of implicit functions to acquire texture coordinates at a support surface. By extending this method to composite objects, we prevent the appearence of ghosting effects at the blend...

In a composite model of leptons and quarks, composite particles with heavy Majorana particles appear provided that the V-rishon is regarded as a Majorana particle. In this paper, the decay mode of such “Majorana partners” is investigated. It is shown that the life time of Majorana partners are fairly long. Our model suggests that a new mechanism of proton decay is possible, where the X and Y bo...

A new type of wood plastic composite, Eucalyptus/PES(Polyethersulfone) blend, was developed. It was designed to be used in LS (Laser Sintering) with reduced energy usage with cost savings. The preparation of Eucalyptus/PES blend and part sintering were under fixed processing conditions and parameters. Through mechanical testing, it was discovered that the strength of prototypes is low due to th...

The paper aims to present the experimental data retrieved after ultrasonic non-destructive testing on metallic particle reinforced polymeric composite materials. The particles’ size (μm), volume fraction as well as the matrix material (different types of polymeric materials – e.g. epoxy, vinyl epoxy, etc.) has their influence on the overall elastic characteristics of the composite material. On ...

Unified nonlinear spinorfield models are self-regularizing quantum field theories in which all observable (elementary and non-elementary) particles are assumed to be bound states of fermionic preon fields. Due to their large masses the preons themselves are confined and below the threshold of preon production the effective dynamics of the model is only concerned with bound state reactions. In p...

Latex nanoparticles were packed inside nanometer-thick titania/polymer composite nanotubules templated by porous alumina membrane, to give free-standing particle-in-tubing "micro-beanpods" after removal of the template membrane.

An excellent ternary composite photocatalyst consisting of silver orthophosphate (Ag3PO4), attapulgite (ATP), and TiO2 was synthesized, in which heterojunction was formed between dissimilar semiconductors to promote the separation of photo-generated charges. The ATP/TiO2/Ag3PO4 composite was characterized by SEM, XRD, and UV-vis diffuse reflectance spectroscopy. The co-deposition of Ag3PO4 and ...

studies were carried out on the preparation and properties of the composites made from cellulose acetate butyrate and cellulose acetate propionate with various amounts of barium strontium titanate nano-particle. the nano-particles of barium strontium titanate (bst) with formulation of ba0.77sr0.23tio3 were made by sol-gel method and their purity and particle size were analyzed by x-ray diffract...

frustration: elementary quasiparticles and many-particle bound states. Abstract The excitation spectrum of the two-chain S = 1/2 Heisenberg spin ladder with additional second neighbor frustrating interactions is studied by a variety of techniques. A description, based on a mapping of the model onto a Bose gas of hard-core triplets is used to determine the one-and two-particle excitation spectra...

Hierarchically mesoporous TiO2 (anatase) sub-micron spheres with uniform particle size exhibiting high Li storage capacity and good cycling performance have been successfully prepared in a large quantity by using TiO2-CdSO4 composite as intermediate.
