Lunch Box Size Portable Gas Chromatograph Portfolio 

The University of Illinois at Urbana-Champaign is seeking partners to further develop this suite of small gas chromatographs. This portfolio of eight patented technologies is available for ready-to-sign licensing. The technologies within this bundle can also be licensed individually.

Novel Microcombustor for Highly Efficient Generation of Electric Power from Fuel Microcombustor (T99041)

This technology is a microcombustor a compact, submillimeter device that burns hydrocarbon fuels homogeneously as a source of power. It efficiently converts heat generated by combustion into electric power, and has the potential to replace batteries in portable applications requiring long-term power. This device is actually the burner, and will eventually form the core of a system that includes peripheral technologies, such as thermal isolation.

Highly Efficient Microcooling/Heating Device (T97057)

A compact active vapor compression cycle heat transfer device. The device of the invention includes a flexible diaphragm serving as the compressive member in a layered compressor. The compressor is stimulated by capacitive electrical action and drives the relatively small refrigerant charge for the device through a closed loop defined by the compressor, an evaporator and a condenser. The evaporator and condenser include microchannel heat exchange elements to respectively draw heat from an atmosphere on a cool side of the device and expel heat into an atmosphere on a hot side of the device. The overall structure and size of the device is similar to microelectronic packages, and it may be combined to operate with similar devices in useful arrays.

Gateable Nanofluidic Interconnects for Three-Dimensional Microfluidic Architectures: Intellipore (TF01056)

The Intellipore technology is a membrane system and method for creating complex, three-dimensional microfluidic devices with improved interconnect functionality.

Intellipores interconnects are intelligent pores that are voltage-gated and externally controllable. Comprised of nanopore membranes and microfluidic channels, this technology enables highly selective flow control and rapid, real-time, intelligent molecular transport in threedimensional microfluidic devices, enabling structures which are analogous to Very Large Scale Integration (VLSI) structures in microelectronics.

High Gain Selective Preconcentrator For Gas Sampling (TF05139)

Novel metal organic framework (MOF) molecules and methods of synthesizing them are described. MOFs are organometallic crystalline structures that have high sorption capacity due to high surface area, tailorable selectivity, an inert nature, and thermal stability at high temperatures.

MOFs may be used as sorbents in preconcentrators for analytical devices to provide orders of magnitude of improved sensitivity in analyte detection. MOFs are also useful as sorbents in new compact and portable micropreconcentrator designs such as a modified purge and trap system and a multi-valve microelectromechanical system (MEMS) to achieve high gain in analyte detection.

A Touch Mode Capacitance Microvalve with High Speed, Microsecond Switching (TF05143)

A bi-directional electrostatic microvalve includes a membrane electrode that is controlled by application of voltage to fixed electrodes disposed on either side of the membrane electrode. Dielectric insulating layers separate the electrodes. One of the fixed electrodes defines a microcavity. Microfluidic channels formed into the electrodes provide fluid to the microcavity. A central pad defined in the microcavity places a portion of the second electrode close to the membrane electrode to provide a quick actuation while the microcavity reduces film squeezing pressure of the membrane electrode.

Multi-functional Multi-layered Nano- & MicroFluidic Device (TF05207)

This technology describes a fabrication method for multi-channel, multi-layered microfluidic devices, with numerous functional characteristics capable of integration into a lab-on-a-chip platform. The chip allows broader analytical capabilities in point-of-use microfluidic technology than previously possible, and it does so with exceeding strength and stability.

GC Column Shapes and Passivation (TF07153, TF07154)

Improved micro-columns and methods for producing micro-columns particularly suitable for use in gas chromatographs are disclosed. In particular, following deposition of the stationary phase coating, the micro-columns are subjected to a postcoating treatment with a molecule that binds to the active sites in the stationary phase micro-column thereby eliminating or reducing loss of gas chromatograph performance associated with those active sites. The postcoating treatment molecule binds to the same active sites as the analytes of interest.
