ORNL researchers invented a detector that uses photoacoustic waves to excite a vibratory sensor coated with unknown molecules. This invention can be used to identify these molecules and study solid, gas, or liquid samples. The device is an advance over other photoacoustic spectroscopy techniques, because it uses a vibratory sensor instead of a resonant chamber and microphone. This approach is …

Glass Capacitor for High-Temperature Applications To meet the demand for smaller, lighter capacitors that have high energy densities, an ORNL researcher developed a capacitor made of glass rods that is constructed like insulated wire. This device can be used for power factor correction, high-voltage capacitors, power electronic filters, energy storage, and components in electric and hybrid-electr…

Method of Rapidly Screening Buffer Layers in Photovoltaics This ORNL invention offers a new method to characterize the electrical properties of a material over a large area. Current methods permit measurement of only one spot of a substrate material at a time; the new method can measure the impedance of many spots on a large substrate simultaneously. This approach is particularly useful for solar…

Superhydrophobic Coating for Evaporative Purification and Minerals Extraction Researchers at ORNL are using their superhydrophobic coating technology to tackle the age-old problem of obtaining potable water. In the process, they have also developed a cost-effective method to extract industrial minerals and metals such as potassium, lithium, and magnesium from the seas and other waters. Potable w…

To improve rates of nuclear power generation, ORNL has patented a way to increase the thermal conductivity of uranium oxide UO 2 fuel. This is achieved by adding high conductivity fibers to form a composite UO 2 fuel pellet. Essentially, the invention is a nuclear fuel pellet with a UO 2 matrix in which long fibers of a high conductivity material are randomly dispersed to act as heat conduits th…

Collimating Adaptor for ORTEC High Purity Germanium Detective UT-B ID 201002500 This invention builds on the technology in the well-known ORTEC Detective family of hand-held radiation detecting devices, providing additional shielding from background radiation and repeatability of measurement geometry for improved measurement in the field. The device can be used to make accurate spectral measure…

Superoleophilic Particles and Coatings Researchers at ORNL have developed a superoleophilic coating that pins a layer of oil to a specially coated substrate and particularly to the surface of the coating. The pinning action keeps the oil from leeching out of the coating, even when the coating is submerged in water or subjected to very wet conditions. This enables the oil to persist on the surfa…

Superhydrophobic Thin Film Coatings Exploiting its expertise with thin films and superhydrophobic materials, ORNL has developed a simple, inexpensive way to apply and reliably bond superhydrophobic powder to various substrates, creating coatings that are both transparent and water repellant. Because of their many advantages and applications, numerous efforts have been made to develop superhydro…

A small appliance developed at ORNL dehumidifies air and then recycles heat to warm water in a water heater. The device circulates cool, dry air in summer and warm air in winter. In addition, the invention can cut the energy required to run a conventional water heater by an estimated 50 per cent. Conventional electric water heater designs have reached the limit of efficiency. The ORNL technology…

Intrinsic features matched across image pairs. Intrinsic Feature-Based Pose Measurement for Medical Imaging Motion Compensation Tomographic imaging of awake, unrestrained animals or humans during a scan can result in blurring and unusable 3D images due to movement by the subject. This invention measures and tracks the motion of an awake subject during a medical imaging scan using only the natural…
