Abstract:
Process and apparatus (10) are disclosed for capturing and converting an ozone-depleting alkyl halide fumigant from a fumigant/air mixed stream (14) by absorbing it into a metal hydroxide-alcohol buffer solution (26) in an absorber/scrubber (12) to produce a fumigant-free air stream (28). The captured alkyl halide in aqueous alcohol solution can actively react with the metal hydroxide in alcohol solution to produce a value-added product, such as a precipitate metal halide, and another alcohol that further enhances absorption. The absorbing solution is well-mixed with make-up alcohol and alkali streams to maintain the concentration of the metal hydroxide in the desired buffer solution range. The solid precipitate metal halide (52) is separated from the liquid stream, and the metal hydroxide-containing mixed alcohol stream (26) is recycled to the absorber/scrubber (12).
Abstract:
The present invention relates to a method and apparatus for the generation, manipulation and detection of plasmon, and/or solitons, both linear and non linear, in semi-conductor heterostructures. The apparatus includes a galium arsonide substrate, a two-dimensional electron gas well (2-DEG) (160) form thereon and a thin layer of Aluminum galium arsonide (AlGaAs) placed thereover. Launcher (130) and receiver lines (132, 134, 136) are formed on the AlGaAs layer. Each of the launcher (130) and receiver lines (132, 134, 136) includes coplanar waveguides which preferably consist of two to three metal lines. One line is interconnected with a photoconductive switch (120) and can be pulsed. The other line or lines are grounded. Pulsing the line forms an electric field which can be detected. Between the launcher and (130) and the receiver (140), the plasmon can be modulated by one or more additional gates line extending over the 2-DEG.
Abstract:
A method for authentication between multiple communication parties is disclosed. Authentication can be carried out by the means of each communication party having a device having a physical unclonable function. To make this possible, the devices have a known quantum correlation that can be used in conjunction with entangled photons to verify the identities of the devices.
Abstract:
A biomaterial structure for proliferation of stem cells includes at least one lattice sub-structure, and a structural gradient in which one or more geometrical features of the biomaterial structure varies along at least one dimension of the biomaterial structure in three-dimensional space. In some embodiments, the structural gradient is accomplished by the first and second lattice sub-structures having at least one different geometrical parameter.
Abstract:
A method for creating oil-filled porous anodic oxide coatings for stainless steel is disclosed. The coating has anti-corrosion and omniphobic properties to resist both atmospheric conditions, or other conditions with exposure to vapor, and wet conditions, in which the coating is exposed to and/or immersed in liquid. The anodic oxide coating of the present invention can be made by the steps of cleaning and/or electropolishing a steel substrate, applying anodic oxidation to the steel substrate, washing the steel substrate in an organic solvent, and annealing the substrate at high temperature. To fill the porous coating with an oil, a solvent exchange method may be applied.
Abstract:
A device for generation of genuine random numbers, uses quantum stochastic processes in optical parametric nonlinear media. The dimensionality of the random numbers is varied from 2 to over 100,000. Their statistical properties, including the correlation function amongst random numbers, are tailored using linear and nonlinear optical circuits following the parametric nonlinear media. Both the generation and manipulation of random numbers can be integrated on a single nanophotonics chip. By incorporating optoelectric effects, fast streams of random numbers can be created in custom statistical properties, which can be updated or reconfigured in real time, such as at 10 GHz speed. The unpredictability of the random numbers is quantifying by evaluating their min-entropy. The genuineness of quantum random numbers is tested using both statistical tools and independently verified by measuring the quantum entanglement between the photons in real time reducing vulnerability to hostile attack.
Abstract:
The described invention provides an ex vivo dynamic multiple myeloma (MM) cancer niche contained in a microfluidic device. The dynamic MM cancer niche includes (a) a three- dimensional tissue construct containing a dynamic ex vivo bone marrow (BM) niche, which contains a mineralized bone-like tissue containing viable osteoblasts self-organized into cohesive multiple cell layers and an extracellular matrix secreted by the viable adherent osteoblasts; and a microenvironment dynamically perfused by nutrients and dissolved gas molecules; and (b )human myeloma cells seeded from a biospecimen composition comprising mononuclear cells and the multiple myeloma cells. The human myeloma cells are in contact with osteoblasts of the BM niche, and the viability of the human myeloma cells is maintained by the MM cancer niche.
Abstract:
Apparatus and method for diagnosing a source of muscular pain, wherein the apparatus (10) includes a housing (12), an electrical signal generator (52) mounted within the housing (12), and a pair of electrodes (18, 20), one of which is mounted on one end (14) of the housing and the other of which is mounted on an opposite end (16) of the housing. The generator (52) may include either an analog waveform generator or a digital signal processor (413). Each of the electrodes (18, 20) stimulates a muscle with an electrical signal generated by the generator (52). One of the electrodes (18) has a relatively small contact area for targeting smaller muscles or muscle groups, while the other electrode (20) has a relatively large contact area for targeting larger muscles or muscle groups. The apparatus (10) is a self-contained, wireless unit and is highly maneuverable, which allows a user to quickly and easily diagnose a source of muscle pain.
