Thomas R. Blake, a noted mechanical engineer, has been named dean of the Newark College of Engineering (NCE), New Jersey Institute of Technology (NJIT). As dean, Blake will have overall responsible for NCE, which has seven engineering programs, two interdisciplinary programs, more than 3,500 students and 160 professors. Founded in 1919, NCE is one of the region's premier engineering schools. About one in four professional engineers in New Jersey is an NCE graduate, and some 25,000 of the college's alumni work in every region of the world, often as chief executive officers or presidents of large engineering firms. >>
Drugs, food, cosmetics, ceramics, electronics, and specialty chemicals--these products and others are all made up of particles. Making those particles smaller can drastically and significantly affect the properties of such products, sometimes resulting in unique "added value" both to the particles and the end product.   Kicking off the first of an eight-lecture series sponsored by NJIT's mechanical engineering department, Prof. Rajesh N. Dave will speak on that topic September 24, from 4 p.m. to 5:30 p.m. at the Mechanical Engineering Center, Rm 224.  The title of his address is "Synthesis and Processing of Engineered Particulates."   As the director of the New Jersey Center for Engineered Particulates at NJIT, Dave is an expert on engineered particulates. The center's research is focused on producing three types of such engineered particulates. These are coated particles that have a layered or ordered structure, "designer" particles with controlled size or structure, and composite particles with a homogeneous structure.   A major focus of Dave's talk will be coated particles. Materials with relatively large particle size form a core, making them "host" particles. These "host" particles can then be mechanically coated with "guest" particles, of fine submicron size. No liquid of any kind, either solvents, binders, or water, is needed. Dave will review a number of different devices used to achieve dry particle coating, giving examples to illustrate how this approach can create materials with novel or enhanced properties. Using supercritical-fluid-based techniques, particles as small as 20 nanometers can be coated. Finally, Dave will discuss discrete-element-method-based modeling of these processes.   Dave received his undergraduate degree in mechanical engineering from the Indian Institute of Technology in Bombay and his master's and doctorate degrees from Utah State University. His NJIT research is supported through federal, state, and industrial awards totaling more than $7 million. >>
