Jefferson A. Cuadra, of West New York, Receives Honor for his Research at NJIT

Jefferson A. Cuadra, of West New York, an undergraduate student at NJIT, received the first prize gold medal for his undergraduate project, “Destabilization of Pickering Emulsions Using Vibrations.”  The award was presented at the annual NJIT Dana Knox Student Research Showcase at NJIT on April 14, 2010. 

The stabilization of emulsions is mostly applied in crude oil recovery, oil separation, cosmetic preparation and water treatment.  In addition, it has also recently been used in semi-permeable capsules for drug delivery, food additives, and biomedical applications.  

The two methods to achieve the stabilization are Pickering emulsions and the use of an emulsifier.  A Pickering emulsion occurs when one liquid is dispersed in another, both being immiscible; and micro-solid particles, called surfactants, prevent the droplets from splitting up to balance the amount of energy in the mixture. 

The experiment used a mixture containing oil, water, and glass particles (silica-Si02) and tested at different frequencies using an electrodyamic shaker and accelerometer sensor.  Silica micro solid particles were used as surfactants because they are more stable than normal emulsions. 

The purpose of the experiment was to analyze if vibrations controlled by a power amplifier and vibration exciter control affected the destabilization time of this type of emulsion.  The time interval of destabilization without any frequency was analyzed and plotted.

NJIT, New Jersey's science and technology university, enrolls approximately 10,000 students pursuing bachelor's, master's and doctoral degrees in 120 programs. The university consists of six colleges: Newark College of Engineering, College of Architecture and Design, College of Science and Liberal Arts, School of Management, College of Computing Sciences and Albert Dorman Honors College. U.S. News & World Report's 2012 Annual Guide to America's Best Colleges ranked NJIT in the top tier of national research universities. NJIT is internationally recognized for being at the edge in knowledge in architecture, applied mathematics, wireless communications and networking, solar physics, advanced engineered particulate materials, nanotechnology, neural engineering and e-learning. Many courses and certificate programs, as well as graduate degrees, are available online through the Division of Continuing Professional Education.
