Research Highlights

The Scanning Electron Microscope (SEM) image of an ant, as demonstrated for a high-school outreach program, has inspired Assistant Professor Jun Yao of the Electrical and Computer Engineering Department at the University of Massachusetts Amherst to develop bioinspired, ultrasensitive pressure and strain sensors using microparticles resembling the bristles or tactile hairs ubiquitous in insects. “My hope was that the extremely enlarged image of an ant, perhaps a bit scary and monster-like, would excite the students’ interest in the ordinarily invisible nanoscale domain,” says Yao. Much...

In mid-October, Professor Jonathan Rothstein of the Mechanical and Industrial Engineering Department ran his annual STEM Outreach event at the Houston Children's Museum. “This is the fifth time we have run this event ahead of the Society of Rheology meeting,” said Rothstein. “It is a program that I developed for the Society of Rheology. We have averaged over 300 kids and 30 volunteers over the last five years.”

Rothstein added that “In...

A research team led by Qiangfei Xia of the Electrical and Computer Engineering Department at the University of Massachusetts Amherst has just published a paper in the prestigious journal Nature Nanotechnology about research into a promising building block for the next generation of nonvolatile random access memory and bio-inspired computing systems. The research team says that its working memristor crossbar arrays are “to the best of our knowledge, the first high-density electronic circuits with individually addressable components scaled down to two-nanometer dimension built...

Guangyu Xu of the Electrical and Computer Engineering Department is part of a team of scientists based at UMass Amherst that has been awarded a four-year, $953,300 grant from the National Science Foundation (NSF) to develop miniature, implantable hardware, which can record complex brain activity in animals and analyze it in real time. See News Office release. The NSF funding is part of $16 million given to 18 cross-disciplinary projects around the country to conduct innovative...

“Is there a difference between a rotary and a roundabout?” Boston Globe correspondent Morgan Hughes asked a very New-England-centric question in a recent edition of the Globe. “Transportation experts at the University of Massachusetts Amherst have the answer.” Yes, the UMass Transportation Center has launched a series of informational videos that explore a range of issues often questioned by the driving public. The series is made up of...

Inside UMass reports that two scientists at UMass Amherst, including Professor Sarah Perry of the Chemical Engineering Department, are building a new class of environmentally friendly polymer materials made from complex coacervates that contain solid nanoparticles. The scientists hope their research into these new complex coacervates will have a radical impact on applications ranging from polymer coatings to vaccine formulation.

A new paper by a research team led by Qiangfei Xia, Daniel Holcomb, and Joshua Yang of the Electrical and Computer Engineering Department at the University of Massachusetts Amherst describes a pioneering new technique to support the safe use of all-important “digital keys” in protecting hardware security systems and producing more secure, compact, and efficient memristive hardware. The paper, titled "A provable key destruction scheme based on memristive crossbar arrays," has just been published in the...

Professor Wen Chen of the UMass Mechanical and Industrial Engineering Department is on a team of scientists from Lawrence Livermore National Laboratory (LLNL), UMass Amherst, and Harvard University working on a process for hierarchical 3-D printing of gold that could revolutionize the manufacture of electrochemical reactors, sensors, and actuators. Chen, a former postdoctoral research scientist at LLNL, helped develop an alloying and de-alloying process that was the key to the findings.
