  • Publication number: 20140263214
    Abstract: An apparatus and method for laser-assisted machining (LAM) of bone without raising the temperature of the surrounding bone is discussed. The method of LAM of bone involves determining a target bone needing to be machined an then scanning a high power density laser beam along the bone at a machining rate that produces low-heat affected zones (HAZ) on the target bone. The process and apparatus is advantageous over conventional technologies because it provides a chemically clean, coherent, and monochromatic beam to the region to be machined.

  • Publication number: 20140263009
    Abstract: A sustainable Low Water Footprint Re-circulating Aquatic System for cultivating aquatic organisms and plants. The system conserves water and energy by using gravity to move water and nutrients from the clarifier into the low water footprint management system. The novel water management system controls the volume of water in the plant grow bed such that it never rises to or above the surface, limiting evaporative water loss. Water flow to the plant grow bed is intermittent and the water management system retains water within the grow bed by capillary action, even when there is no water input. The grow bed contains microflora that convert nitrogenous wastes produced by the aquatic organisms to nitrogenous compounds useable by the plants. The clarified water is then pumped back into the animal tanks. The system is sustainable, cost effective, and highly productive, and uses 50-80% less water than conventional re-circulating aquatic production system.

  • Patent number: 8746398
    Abstract: An acoustic material can be electromagnetically tuned to produce alterations in its acoustical properties without physical contact. The acoustic material should contain a periodic structure and a medium that has acousto-elastical properties that can be altered through the application of electromagnetic radiation. Changes in volumetric properties such as density result in changes to the velocity at which sound passes through the material. The acoustic material can be a phononic crystal that undergoes a change in its acoustic bandgap after being subjected to electromagnetic radiation. This electromagnetic tuning ability results in the ability to change the acoustic properties of various phononic devices without physical contact.

  • Patent number: 8748608
    Abstract: Dopamine D3 receptor antagonists and partial agonists are known to modulate the reinforcing and drug-seeking effects induced by cocaine and other abused substances. By introducing functionality into the butylamide linking chain of the 4-phenylpiperazine class of ligands, improved D3 receptor affinity and selectivity, as well as water solubility, is achieved. A series of linking-chain derivatives are disclosed wherein functionality such as OH or OAc groups have been introduced into the linking chain. In general, these modifications are well tolerated at D3 receptors and achieve high selectivity over D2 and D4 receptors.

  • Publication number: 20140131662
    Abstract: Methods of forming a graphene-based device are provided. According to an embodiment, a graphene-based device can be formed by subjecting a substrate having a dielectric formed thereon to a chemical vapor deposition (CVD) process using a cracked hydrocarbon or a physical vapor deposition (PVD) process using a graphite source; and performing an annealing process. The annealing process can be performed to temperatures of 1000 K or more. The cracked hydrocarbon of the CVD process can be cracked ethylene. In accordance with one embodiment, the application of the cracked ethylene to a MgO(111) surface followed by an annealing under ultra high vacuum conditions can result in a structure on the MgO(111) surface of an ordered graphene film with an oxidized carbon-containing interfacial layer therebetween. In another embodiment, the PVD process can be used to form single or multiple monolayers of graphene.

  • Patent number: 8715395
    Abstract: Fluorinated metal-organic frameworks (“FMOFs”) are capable of adsorbing and desorbing hydrocarbons, namely, C6-C8 hydrocarbon oil components (n-hexane, cyclohexane, benzene and toluene). FMOFs can be arranged in a variety of configurations and have internal hollow channels and cavities. In FMOFs, hydrogen atoms have been substituted completely or partially with fluorine atoms or fluorinated groups in each linking organic ligand. These FMOFs can adsorb C6-C8 hydrocarbons, up to 500 kg/m3 as demonstrated for toluene, through a combination of superhydrophobicity and capillary action. No water adsorption was detectable even under extreme conditions including moist air near 100% relative humidity and immersion in water for multiple weeks, demonstrating far superior water resistance to BPL carbon and zeolites. These materials are stable and can be readily recycled by simple desorption many times.

  • Publication number: 20140060960
    Abstract: Tunable polymer-based sonic structures (“TuPSS”) are made up of sonic structures and polymers. The TuPSS has three general requirements: a) The sonic structure is composed of one or materials engineered to behave as a lens, filter, cloak, or dampener; b) Stimulus sensitive polymer is incorporated into the sonic structure; and c) The actuation of the polymer tunes the acoustic behavior of the structure in a predictable manner. The tunable polymer-based sonic structures utilize stimuli-driven physical properties of the polymers in these acoustic structures to produce a stimulus driven, or tunable, sonic structure or device. The sonic structures actively modulate mechanical vibrations that propagate through the structures, but are passive in that they do not produce mechanical vibrations. The stimuli for the structures include electric, magnetic, electromagnetic, chemical, thermal, and shaking/orientation.

  • Patent number: 8651048
    Abstract: A soft-landing (SL) instrument for depositing ions onto substrates using a laser ablation source is described herein. The instrument of the instant invention is designed with a custom drift tube and a split-ring ion optic for the isolation of selected ions. The drift tube allows for the separation and thermalization of ions formed after laser ablation through collisions with an inert bath gas that allow the ions to be landed at energies below 1 eV onto substrates. The split-ring ion optic is capable of directing ions toward the detector or a landing substrate for selected components. The inventors further performed atomic force microscopy (AFM) and drift tube measurements to characterize the performance characteristics of the instrument.
