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 …

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…

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…

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…

Imaging Based Refractometer for Instantaneous Hyperspectral Refractive Index Detection The invention relates to optics and more particularly to apparatuses and methods for measuring refractive index (RI). Multispectral refractometers typically measure RI at discrete monochromatic wavelengths via a serial process. We report on the demonstration of a white light full field imaging based refractomet…

Triply Redundant Integrated Navigation and Asset Visibility System A quartz time, positioning, and navigation array that solves a fundamental sensitivity problem is under development by ORNL researchers. Existing systems with good timing stability are limited by poor motion sensitivities. In contrast, this invention has stability at a much lower size, weight, and power; better acceleration and sh…

An optical system capable of reproducing three-dimensional images was invented at ORNL. This system can detect height changes of a few nanometers or less and render clear, single shot images. These types of precise, high speed measurements are impor- tant for a variety of nanoscience applications. Imaging offers a compelling alternative to convention scanning because it is faster and does not req…

Sensor Rapidly Measures the Concentration of Oxygen in Fluids To provide rapid measurement of oxygen concentrations in fluids, ORNL researchers developed a sensor that measures oxygen in temperatures from 0 degrees Celsius up to the 200 degrees Celsius commonly found in intake manifolds. The sensor can be used in a variety of applications to quickly and inexpensively detect oxygen levels, inclu…
