"Anode-Free" Sodium Metal Battery

Vanderbilt researchers have developed a new "anode-free" battery architecture for sodium-ion batteries that provide energy densities in excess of 400Wh/kg, which is greater than the maximum theoretical energy density of a conventional lithium-ion battery.

3D Junction Bipolar Membranes: More Efficient and Reliable Electrodialysis

Vanderbilt researchers have developed a unique membrane material for more efficient and reliable eletrodialysis. By utilizing a 3D junction structure, the nanofiber bipolar membrane does not degrade or delaminate during high current passage unlike commercial 2D membranes that are currently available.

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%.

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.

Electrospun Filter Media:Effective Removal of Salt Aerosols

Vanderbilt researchers have developed a specialized filter media to remove salt aerosols from the air. The filter media is able to be merged with other filter components to create a single filter for separating multiple types of airborne particles. Using the developed filter media provides more versatility and functionality to the manufacturing of filters for air and molecular purification products.

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 Performance Battery Electrodes Using Electrospun Nanofibers

A Vanderbilt researcher has developed a new battery electrode that uses particle/polymer electrospun nanofiber mats to increase energy density and decrease the required charge time for the battery. The technique can be used with any high energy density metal-ion batteries such as lithium-ion or sodium-ion.

Nanostructured Molybdenum (IV) disulfide (MoS2) Electrodes

The most common counter electrode materials used for in Quantum dot sensitized solar cells (QDSSCs) quickly become poisoned by sulfide, resulting in significant current drops, which lowers solar cell efficiencies and makes them unsuitable for long-term use in a device. Also, some of these materials are rare and expensive, so replacing them with an inexpensive, earth-abundant material is a desirable goal. This invention uses a Mo foil to produce the desired uniform growth of Molybdenum (IV) disulfide (MoS2) petals from the Mo foil, making the foil both the source of Mo as well as the substrate. This petaled MoS2 electrode shows a vastly improved polysulfide reduction compared to Glassy Carbon, ordinary Mo foil, Pt and Au. The petaled MoS2 electrode lost only 0.63% of its initial current density at -1 V whereas Pt lost 13.58% after only five scans, indicating the petaled MoS2 films are highly stable as cathodes. The technology was tested in a solar device setting, using standard photoanodes to test the efficiency of a device employing petaled MoS2 as its cathode. Devices in which a petaled MoS2 cathode was used achieved nearly fivefold improvement in efficiency over those employing a Pt cathode.
