Model for Predicting the Cloud Point of Biodiesels

Purdue University researchers have developed a model that can accurately predict the cloud point of the mixture of fatty acid methyl esters according to their chemical composition. Since this model is not based on data or statistical methods, it clearly predicts the non-linear behavior of methyl ester mixtures (read more).

Solar Energy Harvesting with LED-Based Displays

Researchers at Purdue University have developed a methodology to harvest solar energy or energy from other light sources using light emitting diode electronic displays. These displays can be used as solar cells to harvest solar energy and convert it to electricity when not being used to display information. Currently, there are devices that display information and devices that harvest solar energy, but no single device that combines both functions (read more).

Real-Time Management of Microgrids for Manufacturing

Researchers at Purdue University have developed a smart microgrid system as part of an innovative load management option to improve energy utilization at manufacturing facilities. The smart feature is an innovative demand-side management (DSM) strategy that manages the intermittent nature of the microgrid and the instantaneous demand of manufacturing processes. The control algorithm requires two input signals, one from the microgrid indicating the availability of renewable energy and another from the manufacturing process indicating energy use as a percent of peak production. Based on these inputs, the algorithm has three modes of operation, normal (business as usual), curtailment (shutting off non-critical loads), and energy storage. In addition, this approach is attractive at manufacturing sites where disruptions to the electric grid negatively affect the manufacturing enterprise on a daily basis (read more).
