The number of persons newly infected with the human immunodeficiency virus (HIV) in the U.S. is about 50,000 each year and has not decreased since the late 1990s. To address this critical problem, the first National HIV/AIDS Strategy (NHAS) was developed in 2010, with a goal to reduce incidence by 25 percent by 2015; but, since that goal was never met, it was delayed until 2020. Now Professor Chaitra Gopalappa of our Mechanical and Industrial Engineering (MIE) Department is receiving a grant of $1,567,348 from the National Institutes of Health (NIH) to answer several critical questions posed by the NHAS and to develop a new model and methods necessary for analyses of these crucial problems.

Lee and Colleagues Publish Foundational Research on Cold Spray Additive Manufacturing

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.

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.
