ABSTRACT


Hot isostatic processing (HIP) is the latest method to produce open porous materials, such as ceramics or metals. In this review paper, features and applications of HIPed porous materials are described. Sintering behavior under high pressure gas is also discussed in order to understand how porous materials are obtained by this method. HIPed porous materials have higher open porosity, higher mechanical strength, narrower pore size distribution and higher fluid permeabili ....etc

Laser Micro-Patterning by Means of Optical Fibers with Micro-grinded Lens End Faces




Introduction

Nano-patterning of polymer surface has found a wide range of applications including biotechnology, where holes in the size of hundreds – nm can influence the growth and differentiation of relatively large living cells . Instead of the e-beam patterning technique used in the Ref. 1, we ap-plied direct writing by laser-light. In our previous papers , w ....etc

abstract

Java language has many features that make it the right choice for the variety of programming tasks
from the server to palmtop. Java language has a level of strong, consistent and extensible security that
is sorely lacking in other languages. Java security was a key consideration in the development of the
language.
Java is primarily used for networking purpose. The developers knew that Java programs would
be exposed to ....etc

On the macro scale, feedback control is routinely applied to improve performance and enable new tasks in complex and uncertain systems operating in noisy environments. Our lab has focused on applying feedback control ideas to systems on the micro scale. Here we show how control methods can improve existing performance in the UCLA lab-on-a-chip electrowetting system and can create entirely new capabilities in our 'micro fluidic tweezers' cell steering devices.In the Electro-Wetting-On-Dielectric (EWOD) system developed at UCLA by CJ Kim, a grid ....etc

Black Holes
A black hole is a region of space from which nothing, not even light, can escape. John Michell, using Newton’s ideas of gravity as a force, saw that if a strong enough gravity were at the surface, that not only could material objects not leave the surface, but light itself may bend and be trapped Karl Schwarzchild (1873-1916) In 1916 used Einstein’s General Relativity to define a Black Hole Defined the “event horizon” gravitational radius of a black hole AKA the … “Sch ....etc
