Method For Forming An Antenna And A Radio Frequency Transponder, Ravi F. Saraf Dec 2003

Method For Forming An Antenna And A Radio Frequency Transponder, Ravi F. Saraf

Department of Chemical and Biomolecular Engineering: Patents

A method is disclosed for forming an antenna and a radio frequency transponder. The method comprises the steps of (1) forming a paste comprising metal powder, polymeric material, and solvent; and (2) screening the paste through a screen onto a substrate. Additional steps couple electrical components to the paste and dry the paste.


Self Assembled Nano-Devices Using Dna, Ravi F. Saraf Dec 2003

Self Assembled Nano-Devices Using Dna, Ravi F. Saraf

Department of Chemical and Biomolecular Engineering: Patents

An article of manufacture including an organic structure and inorganic atoms bonded to specific locations on the organic structure.


Synthesis Of Chemical Tags, Ravi F. Saraf Oct 2003

Synthesis Of Chemical Tags, Ravi F. Saraf

Department of Chemical and Biomolecular Engineering: Patents

A method for forming a biological chemical tag. At least one double stranded DNA molecule is provided. At least a portion of the at least one double stranded DNA molecule is denatured. At least one chemical moiety that prohibits recrystallization of the at least one denatured portion to which the at least one chemical moiety is attached is attached to at least one nucleotide in the at least one denatured portion of the at least one double stranded DNA molecule.


Plasticized, Antiplasticized And Crystalline Conducting Polymers And Precursors Thereof, Ravi F. Saraf Sep 2003

Plasticized, Antiplasticized And Crystalline Conducting Polymers And Precursors Thereof, Ravi F. Saraf

Department of Chemical and Biomolecular Engineering: Patents

Materials containing precursors to electrically conductive polymers and electrically conductive polymers are described which have a high degree of crystallinity. The high degree of crystallinity is achieved by preparing the materials under conditions which provide a high degree of mobility to the polymer molecules permitting them to associate with one another to form a crystalline state. High levels of electrical conductivity are achieved in the electrically conductive materials without stretch orienting the material. The enhanced electrical conductivity is isotropic as compared to a stretch oriental film which has isotropic electrical conductivity.


Micro Goniometer For Scanning Probe Microscopy, Ravi F. Saraf Apr 2003

Micro Goniometer For Scanning Probe Microscopy, Ravi F. Saraf

Department of Chemical and Biomolecular Engineering: Patents

A goniometer for performing scanning probe microscopy on a substrate surface is disclosed. The goniometer has a cantilever, having a cantilevered end and a supported end and a tip disposed at the cantilevered end of the cantilever. The goniometer also has a block disposed at the supported end of the cantilever. The block has at least one pair of piezoelectric layers, a pair of electrodes disposed about each individual piezoelectric layer such that varying a potential difference applied between the individual electrodes of a pair of electrodes causes the corresponding piezoelectric layer to deform, and a first insulating material disposed …


Ferroelectric Storage Read-Write Memory, Ravi F. Saraf Apr 2003

Ferroelectric Storage Read-Write Memory, Ravi F. Saraf

Department of Chemical and Biomolecular Engineering: Patents

A memory device including at least one pair of spaced apart conductors and a ferroelectric material between the pair of conductors. The pair of conductors is spaced apart a distance sufficient to permit a tunneling current there between.
