Researchers to study the impact of toxic properties on the environment

Author: Brandi Klingerman

More advanced manufactured materials are being produced in the 21st century, including, for example, engineered nanoparticles whose exact impact on the environment and human health are unknown, but whose effects could be quite negative. To better understand such threats, researchers are using the Notre Dame Linked Experimental Ecosystem Facility (ND-LEEF) to study how these engineered nanoparticles will move and spread in the natural environment.

A New Class of Spin-Wave-Based Devices May Improve Overcrowded Electromagnetic Spectrum

Author: Nina Welding

Grocery stores. Coffee shops. Even some cities offer public WiFi. Add to those access points the number of private WiFi networks that exist and it’s easy to understand why the allocation and usage of the electromagnetic spectrum — the number of “channels” available for wireless communication — is stretched to its limits. The impending demand of machine-to-machine (M2M) and Internet-of-Things (IoT) devices will put even more of a strain on spectrum usage. Possible solutions to this problem, such as dynamic spectrum access and cognitive radios, have been proposed but their success is based upon a more efficient use of the spectrum.

Engineering Faculty Awarded DURIP Grants for Tunable Laser System and Transonic Wind Tunnel Research

Author: Nina Welding

Highly competitive, the annual DURIP awards process is a merit competition conducted jointly by the Army Research Office (ARO), Office of Naval Research (ONR), and Air Force Office of Scientific Research (AFOSR). This year the DoD received more than 685 proposals. Approximately 160 of the proposals have been or will be funded. To date Notre Dame faculty — David Bartels, David Go, and Scott Morris — have received two Department of Defense (DoD) Defense University Research Instrumentation Program (DURIP) grants for 2017, totaling more than $773,000.

Notre Dame Researchers Open Path to New Generation of Optical Devices

Author: Nina Welding

Cameras, telescopes and microscopes are optical devices that measure and manipulate electromagnetic radiation [light]. Being able to control the light in these devices provides more information through a better “picture” of what is occurring. Specifically, controlling light on small scales could lead to improved optical sources for applications that span health,
