Lee and Colleagues Publish Foundational Research on Cold Spray Additive Manufacturing

Jae-Hwang Lee

Jae-Hwang Lee

Jae-Hwang Lee, the head of the Nano-Engineering Laboratory in the UMass Amherst Mechanical and Industrial Engineering (MIE) Department, is a member of a multi-institutional and multi-disciplinary team of researchers who co-authored a fundamental materials research article on cold spray additive manufacturing published in the prestigious journal Nature Scientific Report. Cold spray is a materials consolidation process that utilizes micron-sized particles and accelerates them at supersonic velocities through a de Laval rocket nozzle. The impacting particles undergo extreme plastic deformation and then consolidate, thus forming a dense coating with a near net-shaped quality.

Sun Receives $400,000 NSF Grant to Study Deadly and Crippling Neural Tube Defects

Neural tube defects are among the most common birth defects and affect more than 500,000 infants worldwide each year, resulting in severe health problems, including paralysis of legs, brain damage, and even death. Now Professor Yubing Sun of our Mechanical and Industrial Engineering Department has received a $400,000 grant from the National Science Foundation to develop a series of engineered tools to enable the investigation of the poorly understood mechanism that causes neural tube defects.

UMass Team Hits 775 MPG and Snags Fourth Place at National Supermileage Competition

Super Mileage Vehicle crossing finish line

At the 38th annual Society of Automotive Engineers (SAE) Supermileage Competition on June 8 and 9, the UMass team scored an impressive fourth place out of 20 collegiate teams by hitting 775 miles per gallon on the 9.6-mile course at the Eaton Proving Grounds in Marshall, Michigan. See competition website. Though this fourth-place finish was equal to the best ever done by the UMass Supermileage Vehicle (SMV) in recent years, the effort was marred by a fuel leak that cost our team some crucial miles per gallon.
