High Inertance Liquid Piston Engine-Compressor

Inventors at Vanderbilt University have developed a high inertance engine-compressor for use with pneumatically actuated devices, especially those with periods of inactivity between periods of pneumatic use. It utilizes a flexible diaphragm in combination with a liquid piston to achieve high inertance and other operational features such as high efficiency, low noise and low temperature operation.

High Bandwidth, Hot Gas and Liquid, Rotary Proportional Valves

Inventors at Vanderbilt University have developed a high performance rotary servo valve to be used with hot/cold liquids and gases. This valve can be directly actuated by a rotary servo motor, eliminating the need for linear actuating devices. It exhibits a compact design that allows for increased control, precision, and efficiency.

Synthetic Beam Chopper

A new system of signal modulation and lock-in amplification has been developed at Vanderbilt University. The invention serves as a low cost alternative to current mechanical beam choppers and lock-in amplifiers, with lower limits of detection, decreased need for mechanical precision, and improved accuracy.

Diamond Triode Devices with a Diamond Microtip Emitter

This technology is a diamond triode for micro and power electronics. Diamond microtip field emitters are used in triode vacuum electronic devices, sensors and displays. Diamond triode devices having integral anode and grid structures are fabricated using a patented process. Ultra-sharp tips are formed on the emitters in the fabrication process in which diamond is deposited into mold cavities in a two-step deposition sequence. During deposition of the diamond, the carbon graphite content is carefully controlled to enhance emission performance. The tips or the emitters are treated by post-fabrication processes to further enhance performance.

Polar Liquid Crystals with High Dielectric Anisotropy

Vanderbilt inventors have developed a new class of liquid crystals with high dielectric anisotropy. A new class of liquid crystals containing boron in their structure has been developed with high dielectric anisotropy, which results in low threshold voltages.

Enhanced Cooling of Oil Based Transformers and Other Heat Generating Equipment with NanoParticle Suspensions

Nanometer-sized, low-cost, readily available, particulate nanodiamond is used as an additive to the mineral oil used in electrical power transformers and other oil-cooled electrical equipment to enhance the thermal conductivity [TC] and dielectric properties of the oil without compromising the oil's required electrical insulation, such that failures are suppressed, oil life is greatly extended and load boundaries are elevated. This could extend transformer life and allow increases to transformer MVA ratings.

Biohybrid, Photoelectrochemical Energy Conversion Device Based on Photosystem I Deposited Silicon Electrodes

Summary: Aresearch team at Vanderbilt University have developed a biohybrid, photoelectrochemical energy conversion device with multilayer films of Photosystem I (PSI) deposited on silicon electrodes, which yielded an average photocurrent density of 875 µA/cm2; one of the highest reported photocurrent densities for a film of PSI deposited onto an electrode of any material.

Through the Tool Tracking for Friction Stir Welding

Utilizing force sensors mounted on the friction stir welding tool, Vanderbilt inventors have developed a technique to keep a weld tool on track. This technology is especially benefi cial in real time corrections for deviations in travel in the case of robotic FSW or "blind" welds. The technique is cost- effective in that no additional sensors such as cameras, thermocouples, acoustic emission receivers, etc. are required.

Bright White Light Nanocrystals for LEDs

A research team lead by Professor Sandra Rosenthal at Vanderbilt University has developed nanocrystals (~2 nm diameter) that emit white light with very high quantum efficiency. This technology would be a viable cost effective candidate for commercial solid-state lighting applications, such as Light Emitting Diodes (LEDs). These nanocrystals were originally discovered by the same group in 2005; a recent breakthrough in post-treatment results in improving fluorescent quantum yield up to ~ 45%.

Monopropellant-Powered Actuator

This proportional actuator developed at Vanderbilt University is a superior source of controllable power for mobile robots. It utilizes monopropellant or hypergolic bipropellant fuel sources in a controlled manner for more efficient and effective untethered mobile robots performing human mechanical tasks over a prolonged period of time.

Nanofiber Composite Membranes for Alkaline Fuel Cells

A new nanofiber composite membrane morphology and fabrication scheme has been developed at Vanderbilt University to be used for alkaline anion-exchange membrane fuel cells (AAEMFCs). This membrane has high hydroxyl ion conductivity, good mechanical properties, long term chemical stability and low water swelling. Additionally it is well suited for harsh conditions including high temperature and low humidity.

Biphasic Composite for Acidic and Basic Gas Adsorption

Researchers at Vanderbilt University have developed a novel material with high adsorbent capacity for toxic industrial chemicals of low concentrations in air. Due to the broad range of chemicals that can be adsorbed at these capacities, this technology will replace existing commercial and research grade materials serving as respirator adsorbents and single pass filters for a variety of military and non-military applications.

High Energy - Density Hydraulic Accumulator

Vanderbilt inventors propose an inexpensive and easy to manufacture hydraulic accumulator. The proposed hydraulic accumulator technology is intended for energy storage. It is superior to current alternatives in that it provides a simple, efficient and relatively cheap method for storing a large amount of energy in a relatively small volume and mass. One example of its application would be in regenerative braking of passenger vehicles (hydraulic hybrid).
