The paper discusses optimising work on a method of processing ceramic / metal composite coatings for various applications and is based on preliminary work on processing anodes for solid oxide fuel cells (SOFCs). The composite coating is manufactured by the electroless co-deposition of nickel and yttria stabilised zirconia (YSZ) simultaneously on to a ceramic substrate. The effect on coating cha...

Improving the performance of composite energetic materials comprised a solid metal fuel and source oxidizer (known as thermites) has long been pursued thermites for pyrolant flares rocket propellants. The thermites, involving aluminum fuel, can be dramatically improved by utilizing nanometer-sized particles (nAl) leading to vastly higher reaction velocities, owing high surface area nAl. Despite...

An analytical investigation for the creeping motion of a spherically symmetric fluid-permeable composite sphere composed by a uniform porous core and a uniformly surrounded porous shell located at the center of a spherical cavity filled with an incompressible Newtonian fluid is presented here. In the limit of small Reynolds number, the Stokes and Brinkman equations are solved for the flow field...

Fe(3)O(4)@Fe(OH)(3) composite microspheres are highly active, environmentally friendly and easy to recycle catalysts for aldol reactions, which are catalyzed by a solid-liquid interfacial hydrogen bond catalyst at room temperature.

In the modern world, construction industry is successfully developing in various directions. Large-sized structures are replaced by analogues reduced cross-section with help of types reinforcement.
 Frames refer to flat spacer structures. Modern glued frames often solid. Cross-section (lattice) this class were used mainly from solid wood. Currently, they practically not due lack their indu...

In this paper we study the sedimentation of several thousand circular particles in 2D using the method of distributed Lagrange multipliers for solid-liquid ow. The simulation gives rise to ngering which resembles Rayleigh-Taylor instabilities. The waves have a well de ned wavelength and growth rate which can be modeled as a conventional Rayleigh-Taylor instability of heavy uid above light. The ...
