Patent number: 12131894Abstract: A virtual slit cycloidal mass spectrometer and spectrometry methods are disclosed. The spectrometer size-selects particles, which in turn serve as a “virtual slit” for a cycloidal mass analyzer. This virtual slit provides unprecedented resolution in a system that takes up a much smaller physical footprint than was previously achievable. This spectrometer may facilitate field sampling of isotopes, such as uranium isotopes.Type: GrantFiled: May 27, 2022Date of Patent: October 29, 2024Assignees: DUKE UNIVERSITY, ARIZONA BOARD OF REGENTS ON BEHALF OF THE UNIVERSITY OF ARIZONAInventors: M. Bonner Denton, Jason Amsden, Rafael Bento Serpa, Charles Parker, Elettra Piacentino, Rob Kingston, Scott Tilden, Roger Sperline, Justin Keogh

Patent number: 11081331Abstract: Disclosed herein are mass spectrometers having segmented electrodes and associated methods. According to an aspect, an apparatus or mass spectrometer includes an ion source configured to generate ions from a sample. The apparatus also includes a detector configured to detect a plurality of mass-to-charge ratios associated with the ions. Further, the apparatus includes segmented electrodes positioned between the ion source and the detector. The apparatus also includes a controller configured to selectively apply a voltage across the segmented electrodes for forming a predetermined electric field profile.Type: GrantFiled: October 28, 2016Date of Patent: August 3, 2021Assignee: Duke UniversityInventors: Zach Russell, Michael Gehm, Jeffrey T. Glass, Shane Di Dona, Evan Chen, Charles Parker, Jason Amsden, David Brady

Patent number: 8666471Abstract: Provided herein are implantable biomedical devices, methods of administering implantable biomedical devices, methods of making implantable biomedical devices, and methods of using implantable biomedical devices to actuate a target tissue or sense a parameter associated with the target tissue in a biological environment. Each implantable biomedical device comprises a bioresorbable substrate, an electronic device having a plurality of inorganic semiconductor components supported by the bioresorbable substrate, and a barrier layer encapsulating at least a portion of the inorganic semiconductor components. Upon contact with a biological environment the bioresorbable substrate is at least partially resorbed, thereby establishing conformal contact between the implantable biomedical device and the target tissue in the biological environment.Type: GrantFiled: September 28, 2010Date of Patent: March 4, 2014Assignees: The Board of Trustees of the University of Illinois, Northwestern University, Trustees of Tufts College, The Trustees of the University of PennsylvaniaInventors: John A.
