About the CHM

The Center for Hierarchical Manufacturing is an NSF Nanoscale Science and Engineering Center (NSEC). The mission of The Center for Hierarchical Manufacturing (CHM) at the University of Massachusetts is to be a leading research and education center for the development of efficient, cost effective process platforms and versatile tools for the two and three dimensional integration of components and systems across multiple length scales. The approach integrates nanofabrication processes for sub-30 nm elements based on directed self-assembly, additive-driven assembly, nanoimprint lithography, high fidelity 3-D polymer template replication, and conformal deposition at the nanoscale with Si wafer technologies or high-rate roll-to-roll (R2R) based production tools to yield materials and devices with unprecedented performance for computing, energy conversion and human health. The CHM effort is made comprehensive by research on device design, modeling and prototype testing in functional architectures that takes advantage of the specific hierarchical nanomanufacturing capabilities developed by the Center.

UMass Amherst Will Lead Major Federal Initiative in New England to Boost Innovation in Advanced Manufacturing

UMass Amherst

The U.S. Department of Defense (DOD) today named the University of Massachusetts Amherst as the lead institution in New England for its national Flexible Hybrid Electronics (FHE) Manufacturing Innovation Institute, a $75 million federal initiative to create a competitive, effective and sustainable research-to-manufacturing collaboration between U.S. industry and academia to solve problems in advanced manufacturing.

Prof. Harry Bermudez Interviewed by ACS Chemical and Engineering News

Harry Bermudez

Before Harry Bermudez was even born, his parents decided to pack up and leave their home, family, and friends in Colombia to make a new life in New York City. It wasn’t an easy move, Bermudez says. They had a three-year-old child, Bermudez’s older brother, and they had to leave behind the life they had known. But economic and political factors drove them to the U.S., which Bermudez says was like a beacon of hope for them.

UMass Advanced Roll-to-Roll Manufacturing Facility

UMass Integrated Life Sciences Building

The design for the Advanced Print and Roll-to-Roll (R2R) Manufacturing Facility at the University of Massachusetts Amherst has been completed and tool acquisition is presently underway. The facility, made possible through a grant to the campus by the Massachusetts Life Sciences Council, is a component of the Center for Personalized Health Monitoring at UMass, and will support translational R&D through multiple departments on campus to develop next generation wearable sensor technologies while providing an industry collaboration and manufacturing demonstration facility to accelerate the commercialization of advanced flexible hybrid electronics technologies and products.

Promising New Method Found for Rapidly Screening Cancer Drugs

Nano screen

UMass Amherst researchers invent fast, accurate new nanoparticle-based sensor system

Traditional genomic, proteomic and other screening methods currently used to characterize drug mechanisms are time-consuming and require special equipment, but now researchers led by chemist Vincent Rotello at the University of Massachusetts Amherst offer a multi-channel sensor method using gold nanoparticles that can accurately profile various anti-cancer drugs and their mechanisms in minutes.

Blades of Grass Inspire Advance in Organic Solar Cells

Organic Single-Crystalline NanopillarsUsing a bio-mimicking analog of one of nature’s most efficient light-harvesting structures, blades of grass, an international research team led by Alejandro Briseno of the University of Massachusetts Amherst has taken a major step in developing long-sought polymer architecture to boost power-conversion efficiency of light to electricity

Professor James Watkins featured in a Fox 25 News Boston Interview

Boston Fox 25 NewsResearch in the Watkins and Carter groups and others in the NSF Center for Hierarchical Manufacturing (CHM) is featured in a Fox 25 News Boston interview. Jim Watkins discusses how nanotechnology is being applied in developing cost-effective body sensor patches to measure stress in military personnel.

UMass Patch Would Spot Stressed-out Soldiers

Nano PatchFitness bands and other wearable health monitors are all the rage among runners and other athletes who want to keep track of their workouts and measure vital statistics such as heart rate and calories burned. Now military personnel may soon have access to the same technology, in a patch that would be about the size and shape of a Band-Aid, and as flexible.

Based on research from the University of Massachusetts Amherst, the sensor would gauge stress and fatigue among armed services personnel.

“Any time you’ve got someone making a command decision, you want to make sure they’re in the right frame of mind, that they’re alert, that they’re well rested,” says James Watkins, a polymer scientist who is leading the UMass effort.

Thomas Russell Honored by Belgium’s Université​ Catholique de Louvain

Thomas RussellThe Institute of Condensed Matter and Nanosciences of the Université​ catholique de Louvain in Belgium on May 27 conferred the title of doctor honoris causa on Thomas Russell, the Silvio O. Conte Distinguished Professor in the department of polymer science and engineering.

The honor pays tribute to his “fundamental contributions to polymer science and to the ingenious applications derived from them, particularly in the field of controlled block copolymer assembly for nanotechnology, and of the structure of functional polymers at interfaces and in the bulk.”

Roll-to-RollNSF's Center for Hierarchical Manufacturing proves good test bed for large-scale nanomanufacturing designs

There's no shortage of ideas about how to use nanotechnology, but one of the major hurdles is how to manufacture some of the new products on a large scale. With support from the National Science Foundation (NSF), University of Massachusetts (UMass) Amherst chemical engineer Jim Watkins and his team are working to make nanotechnology more practical for industrial-scale manufacturing.
