Patent number: 10640377Abstract: A method to produce high quality single or a few atomic layers thick samples of a topological insulating layered dichalcogenide. The overall process involves grinding layered dichalcogenides, adding them to an ionic liquid, and then using a mechanical method to cause intercalation of the ionic liquid into the van der Waals (VDW) gap between the layers of the metal chalcogenide.Type: GrantFiled: December 27, 2017Date of Patent: May 5, 2020Assignee: The Government of the United States of America, as represented by the Secretary of the NavyInventors: Thomas E. Sutto, Amy Ng, Nabil D. Bassim, Todd H. Brintlinger, Michael S. Osofsky, Rhonda Michele Stroud

Patent number: 9896593Abstract: A method, and an article made therefrom, of: contacting a substrate with a first solution of first polyelectrolyte chains to form a layer of the first polyelectrolyte on the substrate; and contacting the layer of the first polyelectrolyte with a second solution of second polyelectrolyte chains to form a layer of the second polyelectrolyte. The first polyelectrolyte has a polyanion or polycation chain. The second polyelectrolyte has a polyanion or polycation chain of a charge opposite to that of the first polyelectrolyte. The first solution or the second solution is an aggregate-forming solution comprising an ionic species having at least two discrete sites of a charge opposite to that of the polyelectrolyte chains in the aggregate-forming solution. The ionic species forms, via bridging interactions, aggregates of the polyelectrolyte chains that remain intact in the aggregate-forming solution during the contact.Type: GrantFiled: January 3, 2014Date of Patent: February 20, 2018Assignee: The United States of America, as represented by the Secretary of the NavyInventors: Walter J. Dressick, Kathryn J. Wahl, Dmitri Y. Petrovykh, Nabil D. Bassim, Rhonda Michelle Stroud

Patent number: 9091594Abstract: A non-destructive method for chemical imaging with ˜1 nm to 10 ?m spatial resolution (depending on the type of heat source) without sample preparation and in a non-contact manner. In one embodiment, a sample undergoes photo-thermal heating using an IR laser and the resulting increase in thermal emissions is measured with either an IR detector or a laser probe having a visible laser reflected from the sample. In another embodiment, the infrared laser is replaced with a focused electron or ion source while the thermal emission is collected in the same manner as with the infrared heating. The achievable spatial resolution of this embodiment is in the 1-50 nm range.Type: GrantFiled: November 25, 2012Date of Patent: July 28, 2015Assignee: The United States of America, as represented by the Secretary of the NavyInventors: Robert Furstenberg, Chris Kendziora, Nabil D. Bassim, Robert Andrew McGill, Viet K. Nguyen
