A QCA nanocrystal comprises of a plurality of host atoms in a nanocrystal of a size of less than 10 nm with a single atom of a dopant (or activator). This single QCA dopant, when confined, becomes polarized and creates a large magnetic-moment in a nanosize host that contains atoms of unpaired spins. The quantum confined atom (QCA) which is now pinned, triggers the alignment of the host atoms resulting in nanosize magnetic domain. Engineering of nanomagnets based on QCA nanoparticles can be used in different applications such as: sensors, drug delivery, bio-tagging, cell/DNA tagging, magnetic memories and others.Type: GrantFiled: February 12, 2007Date of Patent: August 9, 2011Assignee: Nanocrystals Technology LPInventors: Rameshwar Nath Bhargava, Haranath Divi, Adosh Mehta

Publication number: 20110168436Abstract: A thin film stack (100, 200) is provided for use in electronic devices such as photovoltaic devices. The stack (100, 200) may be integrated with a substrate (110) such as a light transmitting/transmissive layer. An electrical conductor layer (120, 220) is formed on a surface of the substrate (110) or device layer such as a transparent conducting (TC) material layer (120, 220) with pin holes or defects (224) caused by manufacturing. The stack (100) includes a thin film (130, 230) of metal that acts as a barrier for environmental contaminants (226, 228). The metal thin film (130, 230) is deposited on the conductor layer (120, 220) and formed from a self-healing metal such as a metal that forms self-terminating oxides. A permeation plug or block (236) is formed in or adjacent to the thin film (130, 230) of metal at or proximate to the pin holes (224) to block further permeation of contaminants through the pin holes (224).Type: ApplicationFiled: September 24, 2009Publication date: July 14, 2011Applicant: Alliance for Sustainable Energy, LLCInventor: Lin Jay Simpson
