Patents by Inventor Nicolaie A. Moldovan

Nicolaie A. Moldovan has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20090148652
    Abstract: Diamond SPM and AFM probes which are durable, particularly for scanning hard surfaces such as diamond surfaces. Interlayers and seeding can be used to improve diamond deposition, and the diamond can be ultrananocrystalline diamond (UNCD). Tip sharpening improves resolution.
    Type: Application

  • Publication number: 20080131325
    Abstract: A dispensing device has a cantilever comprising a plurality of thin films arranged relative to one another to define a microchannel in the cantilever and to define at least portions of a dispensing microtip proximate an end of the cantilever and communicated to the microchannel to receive material therefrom. The microchannel is communicated to a reservoir that supplies material to the microchannel. One or more reservoir-fed cantilevers may be formed on a semiconductor chip substrate. A sealing layer preferably is disposed on one of the first and second thin films and overlies outermost edges of the first and second thin films to seal the outermost edges against material leakage. Each cantilever includes an actuator, such as for example a piezoelectric actuator, to impart bending motion thereto. The microtip includes a pointed pyramidal or conical shaped microtip body and an annular shell spaced about the pointed microtip body to define a material-dispensing annulus thereabout.
