Engineering Ambassadors Plan Dozens of Local Area Visits for Fall 2017

Published October 19, 2017

The Michigan Tech Engineering Ambassadors (EA) Program is planning 24 visits to local area schools this semester. The program is designed to change the conversation about engineering, starting with creating excitement for engineering disciplines through outreach activities designed for grades 4-9.

Outreach topics for October and November vary from buoyancy and energy in bouncy balls to structures and chemistry in engineering.

Right now there are 21 ambassadors in EA at Michigan Tech, including 10 veteran ambassadors. The program is open to all of Michigan Tech’s engineering majors, who can join at the start of fall or spring semester. The outreach experience is considered to be professional development for University students, allowing practice with brief presentations and hands on activities with kids.

EA is part of a larger network of universities united under one goal: changing the way people talk about engineering.

Carbon Nanotube Project Funding for Andrew Barnard

Published October 19, 2017

News

Andrew Barnard (MEEM/MuSTI) is the principal investigator on a project that has received a $50,000 grant from the National Science Foundation.

The project is titled “I-Corps: Carbon Nanotube Coaxial Noise Control.” This is a six-month project.

By Sponsored Programs.

Abstract

The broader impact/commercial potential of this I-Corps project is to make quiet products and systems that have pipe and duct sound transmission. Systems like automobile exhausts and intakes, building heating and ventilation systems, and fluid flow piping all transmit sound from power generating equipment to human receivers. In order to reduce the amount of noise to which people are exposed, passive and active noise control systems are incorporated in pipe and duct systems. These systems are currently large, heavy and inefficient. The application of a compact and lightweight coaxial active noise control system has potential implications on many industries where size of noise control elements constrain design. More importantly, the reduction of noise in the environment has potential health and wellness benefits for all members of society through environmental stress reduction. Reducing noise emitted from mechanical pipe and duct systems is an important step in reducing overall environmental noise exposure.
