“The new catalyst, developed by Brown University researchers, exceeds Department of Energy targets for performing the oxygen reduction reaction, a key step in generating an electric current in a hydrogen fuel cell. One factor holding back the widespread use of …
“Gently compressed stacks of graphene form sharp crinkles that carry an electric charge, which could be useful in nanoscale self-assembly and other applications. Researchers from Brown University have discovered another peculiar and potentially useful property of graphene, one-atom-thick sheets of …
“Brown University chemists have shown a technique that can identify regions in a liquid crystal system where molecular order begins to emerge just before the system fully transitions from disordered to ordered states. Liquid crystals undergo a peculiar type of …
“Perovskite solar cells are a promising new low-cost photovoltaic technology, but most contain toxic lead; a team led by Brown researchers has introduced solar cells with a new titanium-perovskite material that gets the lead out. A class of materials called …
“At the scale of microdevices, adhesion is one of the most important forces that engineers need to contend with — Brown University researchers have come up with a new way to measure it. Brown University engineers have devised a new method …
“Data transmission studies in the terahertz region show promise to expand the spectrum available for use. The world is running out of bandwidth to support our growing communication demands. This is in part due to “internet of things” technologies which …
“A new approach to calibrating the pioneering BrainGate brain-computer interface allowed three clinical trial participants with tetraplegia to gain control of a computer cursor after just one simple calibration step. PROVIDENCE, R.I.[Brown University] — For a brain-computer interface (BCI …
“The temporary structures, which can be degraded away with a biocompatible chemical trigger, could be useful in fabricating microfluidic devices, creating biomaterials that respond dynamically to stimuli and in patterning artificial tissue. PROVIDENCE, R.I.[Brown University] — Brown University engineers …
“A new software system helps robots to more effectively act on instructions from people, who by nature give commands that range from simple and straightforward to those that are more complex and imply a myriad of subtasks. A new system …
“Robots aren’t generally meant to get confused, but modeling confusion might help make them more useful workmates. As part of an effort to explore ways for humans and robots to work together more naturally and effectively, a team of …
“If someone asks you to hand them a wrench from a table full of different sized wrenches, you’d probably pause and ask, “which one?” Robotics researchers from Brown University have now developed an algorithm that lets robots do the …
“Various Structured Light (SL) methods are used to capture 3D range images, where a number of binary or continuous light patterns are sequentially projected onto a scene of interest, while a digital cam- era captures images of the illuminated scene …
