Wednesday, September 13, 2000 Alexander Wei and other researchers at Purdue University are
studying materials that measure approximately one-billionth of a meter.
Why? They are helping develop new materials for microelectronic devices
and magnetic sensors. They found that at such a small scale, particles are
so fragile and unstable that, if they touch, they fuse together, thereby
changing to physical and magnetic properties. "Physical properties of materials are dependent on size,"
says Wei. He and his colleagues at Purdue University found a way of
putting a protective coating around nanoparticles, preventing them from
fusing with other particles. "The new coating process allows us to stabilize the
particles with magnetic properties, enabling the development of new
materials for microelectronic devices and magnetic sensors. If we can
manipulate particles at this level, perhaps we can increase storage
capacity in computer memory devices," he says. Wei indicated that potential applications include
biomedicine, such as drug delivery systems of probes and sensors designed
to target specific cells or tissues. Nanoparticles are part of a larger
scientific effort called nanotechnology aimed at developing new
technologies at the molecular level. For more information, contact Wei at

Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
