Researchers at Yale University have succeeded in measuring an electric current flowing through a single organic molecule sandwiched between metal electrodes. The feat could pave the way for a new generation of transistors so small that a beaker full would contain more transistors than exist in the world today, or so reports team leader and Yale electrical engineer Mark A. Reed. To capture the historic measurement of current across a single organic molecule, the researchers made a mechanically controllable break junction by gluing a notched gold wire to a flexible substrate. They then fractured the wire to make an adjustable gap. Next, they sandwiched a single molecule of benzene flanked by two sticky sulfur atoms between the two gold electrodes. What's the potential results? "Thousands of silicon transistors can be produced now for less than a penny," Reed explains, "but the dramatic decrease in cost per transistor that we've enjoyed over the last two decades will start to slow down soon." The answer, Reed believes, is to find materials that will assemble themselves into quantum components. E-mail email@example.com.
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
The Industrial Internet of Things is bringing a previously reluctant process industry into the wireless fold. The ability to connect smart sensors to the Internet has spiked the demand for wireless devices in process manufacturing, according to the new study from ARC Advisory Group.
Everyone has had the experience of trying to scrape the last of the peanut butter or mayonnaise from the bottom of a glass jar without getting your hand sticky. Inventor Ron Jidmar thinks he has a solution to all of that nonsense with a flexible jar design that can be squeezed with one hand to lift contents from the bottom to the top of a jar or container, leaving the other hand free to scoop the contents out cleanly.
