Pvilion CEO Colin Touhey
One area of renewable energy we haven’t really covered, at least as of yet, is the wearable sort – including and especially solar clothing that generates power while you go about your daily routine. But it’s still a technology with a ton of potential, and here to discuss that is Pvilion CEO Colin Touhe

Figure 1. Cross-section view of Infineon’s CoolGaN™ GIT device structure
Introduction
Gallium Nitride (GaN) technology plays a major part in the wide bandgap revolution currently sweeping the semiconductor industry and manufacturers are racing to enter this burgeoning market. While the top-level advantages of using GaN devices in power electronics applications are clear (including higher switching frequencies, better performance at high temperatures, and lower power losses), the more subtle but nonetheless important differ

Figure 1. Examples for extrinsic defects in an amorphous layer, mathematically modeled via a local thinning effect in the gate-oxide of SiC devices
Introduction
The unique properties of Gallium Nitride (GaN) and Silicon Carbide (SiC) devices make them increasingly popular alternatives for silicon in power electronics applications. The appeal of SiC devices lies in their ability to offer unipolar device concepts with low switching losses at high voltages, while GaN devices can switch at much higher frequencies. Although these properties enable smaller

Researchers from MIT and elsewhere have created a framework that could enable a robot to effectively complete complex manipulation tasks with deformable objects, like dough or cloth, that require many tools and take a long time to complete.
Imagine a pizza maker working with a ball of dough. She might use a spatula to lift the dough onto a cutting board then use a rolling pin to flatten it into a circle. Easy, right? Not if this pizza maker is a robot.
For a robot, working with a deformable object like dough is tricky because the shape of dough
