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%.

Incorporating Quantum Dots into Additive Manufacturing Processes

Recent studies have shown the benefits that nanocomposite materials have over unmodified materials in regard to mechanical, chemical, and optical properties. Vanderbilt researchers have developed a technique for the incorporation of quantum dots into polymers for use in additive manufacturing processes. The process has been used to create a nanocomposite material with unique absorbance, fluorescence, and ultraviolet (UV) light excitation properties.

Gratings on Porous Silicon Structures for Sensing Applications

In this technology diffraction-based sensors made from porous materials are used for the detection of small molecules. The porous nature of the diffraction gratings that gives rise to an extremely large active sensing area enables a very high level of sensitivity. Specificity is achieved by functionalizing the porous gratings with selective binding species.

Composite Material for Tunable Memristance Behavior

This technology uses combinations of materials with different electronic properties of micro-or nanometerscale grain size to create a memristive device (twoterminal, variable resistance circuit element). Amidst growing interest in memristors, this technology is one of the first to use composite materials, which make the memristive qualities of the material tunable.

Ultrasonic Sensor for Non-intrusive Local Temperature, Transient Temperature and Heat Flux Measurements

An apparatus for measuring the temperature and heat flux of materials through the use of an ultrasonic sensor has been developed at Vanderbilt University. The sensor uses acoustic measurement techniques to determine the heat flux and temperature of material surfaces otherwise inaccessible in particular during system operation in order to enhance monitoring capabilities and reduce unsafe or impaired function due to extreme temperatures.

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.

A Surfactant Based Low Molecular Weight Hydrogelator with Unprecedented Stability

Low molecular weight hydrogelator (LMHG) formulations are rare, but are preferred over polymeric hydrogels because of their improved biodegradability, biocompatibility and disintegration. Unfortunately, existing LMHGs often fall apart under slight environmental changes, seriously limiting their utility. However, the novel LMHG presented here is able to gelate >95% water in both acidic and basic forms, is robust to environmental changes, and has promising utility in controlled drug release, RNA delivery, tissue engineering, cosmetics, cancer therapy, biomaterials and other chemical industries, making it a promising new material for many different industries.

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.

Lanthanide Oxide Nanoparticle Film Deposition Process

Vanderbilt researchers have developed a method for forming a film of lanthanide oxide nanoparticles using electrophoretic deposition. This technique is straightforward to set up and provides thickness control at high deposition rates, enabling site selective particle assembly for any size and shape.
