| 20090260534 | UNDERWATER GRENADE - An underwater grenade and a method for using an underwater grenade. A depth activated, hand emplaced ordnance utilizing safe and arm technology to address underwater threats (such as enemy swimmers) while providing a safe interface with personnel. The grenade is armed after a sequence of events have occurred including reaching a desired depth and a desired passage of time. Failure of any of the events to occur will cause the grenade to be rendered safe. | 10-22-2009 |

| 20100138964 | PROBES FOR ENHANCED MAGNETIC FORCE MICROSCOPY RESOLUTION - Magnetic Force Microscopy (MFM) probe tips that provide enhanced spatial resolution and methods of manufacture are provided. In one aspect, two or more magnetically-decoupled layers may be deposited on an AFM probe in order to create an active magnetic region at about the apex of the probe tip with dimensions less than about 10 nanometers. In another aspect, nanoscale patterning techniques may be employed to fabricate probe tips that possess plateau features. These plateau features may serve as substrates for the deposition of magnetic films having properties similar to magnetic recording media. Machining techniques, such as Focused Ion Beam (FIB) may be further employed to reduce the size of the magnetic materials deposited upon the substrate. Beneficially, because the plateaus of the substrate are substantially flat and of known geometry, and the magnetic properties of magnetic films deposited on flat surfaces are similar to those deposited upon the plateau, the magnetization of the MFM probe tips may be determined to high accuracy. In this manner, fine control over the magnetic properties of MFM probe tips may be achieved, providing enhanced MFM resolution. | 06-03-2010 |
| 20100149676 | THREE-DIMENSIONAL MAGNETIC RECORDING - A multilayered three-dimensional media having a plurality of magnetic sublayers, each of the magnetic sublayers being separated from one another by a non-magnetic layer. The plurality of magnetic sublayers can be a stack of one or more coupled Co/Pd or Co/Pt layers; a layer of Co—Cr alloys optionally containing TiO | 06-17-2010 |

| 20100140792 | GRAPHITE NANOPLATELETS FOR THERMAL AND ELECTRICAL APPLICATIONS - This disclosure concerns a procedure for bulk scale preparation of high aspect ratio, 2-dimensional nano platelets comprised of a few graphene layers, G | 06-10-2010 |
| 20100316557 | CONTINUOUS EXTRACTION TECHNIQUE FOR THE PURIFICATION OF CARBON NANOMATERIALS - Systems and methods for the purification of carbon nanotubes (CNTs) by continuous liquid extraction are disclosed. Carbon nanotubes are introduced to a flow of liquid that enables the separation of CNTs from impurities due to differences in the dispersibility of the CNTs and the impurities within the liquid. Examples of such impurities may include amorphous carbon, graphitic nanoparticles, and metal containing nanoparticles. The continuous extraction process may be performed in one or more stages, where one or more of extraction parameters may be varied between the stages of the continuous extraction process in order to effect removal of selected impurities from the CNTs. The extraction parameters may include, but are not limited to, the extraction liquid, the flow rate of the extraction liquid, the agitation of the liquid, and the pH of the liquid, and may be varied, depending on the impurity to be removed from the CNTs. | 12-16-2010 |
| 20110068290 | CHEMICAL MODULATION OF ELECTRONIC AND MAGNETIC PROPERTIES OF GRAPHENE - Compounds, compositions, systems and methods for the chemical and electrochemical modification of the electronic structure of graphene and especially epitaxial graphene (EG) are presented. Beneficially, such systems and methods allow the large-scale fabrication of electronic EG devices. Vigorous oxidative conditions may allow substantially complete removal of the EG carbon atoms and the generation of insulating regions; such processing is equivalent to that which is currently used in the semiconductor industry to lithographically etch or oxidize silicon and thereby define the physical features and electronic structure of the devices. However graphene offers an excellent opportunity for controlled modification of the hybridization of the carbon atoms from sp | 03-24-2011 |
| 20110110842 | CONTINUOUS EXTRACTION TECHNIQUE FOR THE PURIFICATION OF CARBON NANOMATERIALS - Systems and methods for the extraction of carbon nanotubes (CNTs) by continuous and/or batch processing are disclosed. Generally, a carbon nanotube material including carbon nanotubes (CNTs), carbon nanoparticles (CNPs), and carboxylated carbon (CC) is provided and agitated to produce a well-dispersed mixture. The well-dispersed mixture can be allowed to stand in a vessel having a lower end and an upper end. In some cases, the CNPs settle at the lower end. In some cases, at least some of the CNTs and CC are disposed at the upper end and can be removed in a dispersion, which can be pH adjusted and/or filtered to extract the CNTs from the CC. | 05-12-2011 |
