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.

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.

Vincent Rotello, UMass Amherst Nanochemist, Named a Distinguished Professor

Vince RotelloVincent M. Rotello, the Charles A. Goessmann Professor of Chemistry at the University of Massachusetts Amherst, has been appointed a Distinguished Professor following approval by the UMass Board of Trustees.

Rotello was recommended for the honor by UMass Amherst Chancellor Kumble Subbaswamy and Provost James V. Staros, who cited how he has “creatively and boldly expanded his research from a focus on small molecule host-guest chemistry to his current path-breaking translational explorations of polymers, surfaces and nanomaterials.”

Polymer Scientist Todd Emrick Named to National Academy of Inventors

Todd Emrick

The National Academy of Inventors this week named Todd Emrick, polymer science and engineering, a fellow of the academy, which seeks to recognize the fellows’ “prolific spirit of innovation in creating or facilitating outstanding inventions that have made a tangible impact on quality of life, economic development and the welfare of society.”

Emphasizing the synthesis of new materials in his research laboratory over the past 13 years, Emrick has developed new polymer surfactants, self-healing polymers, nanoparticles and nanoparticle capsules, membrane technology for water desalination and purification, polymeric flame-retardants and new materials for drug delivery.

CHM Pioneering Wearable Biosensors for Personalized Health Monitoring

Chances are good that when medical device manufacturers offer a wearable biosensing patch that will allow a nurse to monitor a patient’s blood sugar or insulin level remotely, for example, it was designed and the prototype built by polymer scientists at the University of Massachusetts Amherst led by Jim Watkins.

Watkins, who directs the National Science Foundation’s Center for Hierarchical Manufacturing (CHM) at UMass Amherst, says its research has helped to establish that such devices are feasible, and projects beginning this month at the new Center for Personalized Health Monitoring (CPHM) should soon lead to prototypes being developed and tested for commercialization.

Thai Thayumanavan Awarded for Outstanding Accomplishments in Research and Creative Activity at the 2013 Faculty Convocation

ThayumanavanSankaran "Thai" Thayumanavan's research spans a broad realm from cancer therapy using novel drug delivery vehicles to generating organic solar-cell materials. His research is most innovative in its design of new and often unorthodox molecules and materials that result in breakthroughs in important areas. One recent such example is Thayumanavan's work in developing fundamentally new molecular design algorithms for nanomaterials that predictably respond to subtle variations in their environment.

Thayumanavan is further renowned for his ability to arrive at practical molecular systems to solve important problems, such as polymer nanogels that are capable of delivering both proteins and small hydrophobic molecules to targeted cells and sub-cellular compartments. His stature in his field is attested to by the extraordinary number of presentations he has been invited to make at international conferences.

Materials and Processes for Flexible Devices and Electronics

Flexible electronics encompass a broad range of technologies impacting emerging applications that have generated significant interest due to the potential commercial opportunities, which in turn has driven research and development in materials, devices, and scaled manufacturing methodologies. A range of materials encompassing organic, inorganic, and composite nanomaterials will enable a range of new consumer products including flexible displays, LED lighting, solar photovoltaics, integrated circuits and data storage. The NSF Center for Hierarchical Manufacturing (CHM) at UMass Amherst, with support from the FlexTech Alliance and the NNN, recently held a one-day Symposium on Materials and Processes for Flexible Devices and Electronics in conjunction with the Center for UMass-Industry Research in Polymers’ (CUMIRP) Spring Polymer Event on May 16, 2013.
