Nanostructured Molybdenum (IV) Disulfide (MoS2) Electrodes for use in Solar Cells

Quantum dot sensitized solar cells (QDSSCs) are a widely studied system for harvesting light and converting it to electrical energy. Quantum dots (QDs) are an attractive photoabsorber because they have large absorption coefficients and their energy of absorption in the visible region can be tuned based on their size. Molybdenum (IV) disulfide (MoS2) is a naturally occurring semiconductor found in nature as the mineral molybdenite that can be synthesized from inexpensive, earth-abundant materials for use in solar cells.

Electrochemically Actuated Optical Modulator

Vanderbilt University researchers have developed a novel approach for creating dynamic, tunable reflective color displays using an electrochemical modulator. The technology can be implemented into devices requiring low power reflective color displays, such as smart watches and e-readers, and is adaptable for spectral control across a broad spectrum of frequencies from the visible to the far infrared. This technology provides a low power, tunable approach for modulating the optical properties of a material.

"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.

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.

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).
