The use of metals for light localization in lasers is a new way of reducing their size and addresses the key issues of electrical contacting and heat sinking. Such lasers can also be reduced in size almost indefinitely by accessing light that couples to collective electron oscillations of the metal, known as surface p…

When ultra high strength steel (UHSS) sheets with tensile strength over 980 MPa are applied in automobiles, there is a risk that a type of hydrogen embrittlement fracture called delayed fracture may occur while a vehicle is in use. This paper summarizes the effects of stress, strain, diffusible hydrogen content and th…

Here, we report a highly simple and general protocol for functionalization of the CoFe(2)O(4) NPs with chitosan polymers in order to make CoFe(2)O(4) NPs disperse and stable in solution. The functionalized CoFe(2)O(4) NPs (denoted as CF-CoFe(2)O(4) NPs) were characterized by scanning electron microscope (SEM), thermog…

BACKGROUND: Invertebrate biominerals are characterized by their extraordinary functionality and physical properties, such as strength, stiffness and toughness that by far exceed those of the pure mineral component of such composites. This is attributed to the organic matrix, secreted by specialized cells, which pervad…

In this paper we present PDE and finite element analyses for a system of PDEs consisting of the Darcy equation and the Cahn--Hilliard equation, which arises as a diffuse interface model for the two-phase Hele-Shaw flow. In the model the two sets of equations are coupled through an extra phase induced force term in the…
