Any materials scientist will tell you that hydrogen is a tough nut to crack. Although the simplest of the atoms, hydrogen in its molecular state is incredibly complex. The long-sought goal of turning the element into a metal, it has been predicted, would require pressure close to that found at the center of the Earth. Researchers at Cornell University (Ithaca, NY) have dispelled that theory: They submitted hydrogen gas to just such pressure, but the element remained unchanged. "It seems," says Cornell's Arthur Ruoff, "that the pressure required for this transition is even higher than previously thought." The researchers found that solid hydrogen showed no signs of looking like a metal at pressures of up to 342 GPa. The pressure at the center of the Earth is about 361 GPa--more than four million times surface pressure. Such incredible pressure was achieved at Cornell by compressing the hydrogen in a diamond anvil cell, a small device consisting of pairs of the highest quality diamonds with tips beveled to one-fourth the diameter of a human hair. The diamonds, 15 in all, ultimately cracked. E-mail firstname.lastname@example.org.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
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.
