Researchers at UIC have developed a low-power physical synthesis (PS) tool DNF-PS for chip design.  This tool simultaneously applies a set of very effective power/timing optimizing transforms (in particular, multiple Vdd, multiple Vth, cell sizing, buffer insertion, cell replication and global re-placement), and does so simultaneously across the entire circuit while satisfying multiple constraints (e.g., on timing, voltage islands, area, congestion).
In stroke research, the hippocampal acute brain slice preparation is a model for studying how neuronal tissue responds to a hypoxic insult.  Additionally, in diabetes research, pancreatic islets preparation and dynamic loading of oxygen and glucose is critical to understand how hypoxia alters the glucose-insulin response of the pancreas.  However, standard techniques using commercial perfusion chambers cannot accurately provide oxygen delivery and control to model hypoxic conditions.
TATP (triacetone triperoxide) has emerged as an explosive of choice for terrorists in recent years, because it is easy to produce, highly explosive, and hard to detect. Some recent examples of TATP use are the Northwest Airlines Flight 253 attempted bombing (2009), the London bombings (2005), and the American Airlines Flight 63 attempted bombing (2001).
Current sensors employed in the detection of gaseous formaldehyde lack the ability to detect formaldehyde at low concentrations.  Those sensors that can perform this task oftentimes take long periods of time to detect the substances and are overwhelmingly expensive to employ.   Additionally, upcoming OSHA and WHO regulations will require that sensors are able to detect significantly lower quantities of formaldehyde.
UIC researchers have developed a nuclear material sensor that detects gamma radiation at room temperature conditions.  This sensor is constructed out of nanoscale materials which allows for reduction of detector size, weight, and complexity.  Compared to similar products on the market, this technology is inexpensive and thus can be used in more applications. The unique design is able to function without cryogenic cooling.
Current methods of performing tensile tests on micro-nano scale material samples have an inherent flaw, namely that true uniaxial loads are difficult to achieve.  Part of this stems from the adaptation of macro-scale testing methods to the micro-nano scale, which has been shown to be inadequate.  Accordingly, the instant technology seeks to achieve true uniaxial loads on micro-nano scale material samples to achieve more reliable test results.
This technology uses mathematical principles to correct for spectral distortions in concert with a novel device capable of holding an individual fiber in tension to thereby permit Infrared analysis of individual fibers.
This technology is a unique method capable of being used to create very reliable NanoFET biosensors – the processing method increases reliability dramatically over currently used methods. Currently, the industry does not possess a feasible method to create NanoFETs for fluidic applications as such environments are quite harsh on the FETs and they tend to fail rapidly.  Processing has been done, up until now, predominantly through a bottoms-up, self assembly, process that lends itself toward failure in aqueous or biological fluidic settings.
A small electronic system, referred to as a quantum dot (QD), possesses discrete energy levels, whose energy spacing can be much larger than room temperature (Note that the term “quantum dot” is used in a very general way: it simply describes an electronic system that possesses discrete energy levels. As long as the electronic states of this quantum dot do not interact with the outside environment (for example, they are not located on a substrate), an electron located in one of these energy levels can in general not transition to another level.
