Abstract:
It has long been assumed in physics that for information to travel in empty space between two parties (the Sender and the Receiver), “physically real” entities have to travel between the parties. The recently discovered technique of interaction-free measurement—wherein the presence of an object is inferred without the object directly interacting with the interrogating light—has caused this basic assumption to be questioned. This technique has found application in quantum key distribution in the form of counterfactual quantum key distribution albeit with limited efficiency. In the present invention, using the “chained” quantum Zeno effect, this logic is taken to its natural conclusion and, in the ideal limit, information can be transferred between the Sender and the Receiver without any physical particles whatsoever traveling between them.
Abstract:
The catalytic composition for the electrochemical reduction of carbon dioxide is a metal oxide supported by multi-walled carbon nanotubes. The metal oxide may be nickel oxide (NiO) or tin dioxide (SnO2). The metal oxides form 20 wt % of the catalyst. In order to make the catalysts, a metal oxide precursor is first dissolved in deionized water to form a metal oxide precursor solution. The metal oxide precursor solution is then sonicated and the solution is impregnated in a support material composed of multi-walled carbon nanotubes to form a slurry. The slurry is then sonicated to form a homogeneous solid solution. Solids are removed from the homogeneous solid solution and dried in an oven for about 24 hours at a temperature of about 110° C. Drying is then followed by calcination in a tubular furnace under an argon atmosphere for about three hours at a temperature of 450° C.
Abstract:
A light concentrating optic for use with a photovoltaic device includes a light pipe having a first end portion for receiving light and a second end portion for outputting concentrated light. An optical element is coupled to the light pipe on the first end portion and configured to form an optical interface between the light pipe and the optical element. The optical element includes at least one light transmitting surface configured to redirect incident light entering the optical element to disperse the light to fall incident on side walls of the light pipe to increase homogeneity and intensity of light through the second end portion.
Abstract:
A dual mode ground penetrating radar includes an enclosure which houses radar electronics. The dual mode ground penetrating radar includes a enclosure housing radar electronics. The dual mode ground penetrating radar further includes a first antenna feed having ferrite loading and extending outside of the enclosure. The dual mode ground penetrating radar further includes a second antenna feed spaced apart from the first antenna feed, the second antenna feed having ferrite loading and extending outside of the enclosure. An RF signal is provided in at least one of the first and second antenna feeds by the radar electronics.
Abstract:
A spring-less buried magnet linear-resonant motor is provided. The motor includes a buried magnet system and a stator operable to produce an alternating magnetic field exerting alternating axial forces on the buried magnet system that has a self-centering force and a required stiffness to reciprocate at a frequency near an alternating current (AC) supply frequency.
Abstract:
Polymer composites are provided, and more particularly, polymer composites of ground date pits disposed in a polymer matrix. The composites can be formed by a process of preparing reinforced polymer composites having a fibril melt fracture surface, including blending a mixture of date pit particulate with a thermoplastic polymer; melting the mixture; and forcing the melt through a die to produce the polymer composite having a fibril containing surface.
Abstract:
Project management systems and methods to streamline project planning, task management, time management, and other similar applications. The method includes filing a request to start a project on a project management system. The method further includes receiving notice that role handlers have been assigned to a plurality of tasks required to complete the project. The method further includes performing at least one task of the plurality of tasks. The method further includes receiving notice that the at least one task has been reviewed by at least one of the assigned role handlers.
Abstract:
A ring laser gyroscope (RLG) includes moveable minors and a Micro-Electro-Mechanical Systems (MEMS) actuator coupled to the moveable minors to cause a respective displacement thereof that induces a phase modulation on counter-propagating light beams relative to one another. The induced phase modulation creates an optical path difference between the counter-propagating light beams corresponding to a virtual rotation that reduces the lock-in of the RLG.
Abstract:
A method and adsorbent composition for removing heavy metals from contaminated water, including mixing a water having a concentration of one or more heavy metals with an adsorbent including granules of a mixture of 3.33 wt % bentonite clay and a siwak stick powder; and collecting water having a reduced concentration of the heavy metal(s).
Abstract:
A method for treating an MTBE-contaminated aqueous solution includes forming an adsorbent by treating fly ash with nitric acid and then doping the resultant acid-treated fly ash particles with AgNO3 and calcining. The adsorbent is used to contact an MTBE-contaminated aqueous solution to adsorb the MTBE and the adsorbent and to form a purified aqueous phase which is then separated from the adsorbent.
