Journal ArticleDOI
Accessing analytes in biofluids for peripheral biochemical monitoring
Jason Heikenfeld,Andrew J. Jajack,Benjamin Feldman,Steve W. Granger,Supriya Gaitonde,Gavi Begtrup,Benjamin Katchman +6 more
TL;DR: The range of biochemical analytes that can be sensed in dermal interstitial fluid, saliva and sweat are surveyed, and criteria for tailoring sensor design to address the right analyte in the right body site for the right disease or wellness application are outlined.
Journal ArticleDOI
Near-edge x-ray absorption fine-structure investigation of graphene.
Daniela Pacilé,Marco Papagno,A. Fraile Rodríguez,Marco Grioni,L. Papagno,Caglar Girit,Caglar Girit,Jannik C. Meyer,Jannik C. Meyer,Gavi Begtrup,Gavi Begtrup,Alex Zettl,Alex Zettl +12 more
TL;DR: The near-edge x-ray absorption fine-structure (NEXAFS) spectrum of a single layer of graphite (graphene) obtained by micromechanical cleavage of highly ordered pyrolytic graphite on a SiO2 substrate is reported.
Journal ArticleDOI
Shrinking a carbon nanotube.
TL;DR: The combination of defect formation via electron irradiation and simultaneous resistive heating and electromigration in vacuum causes the nanotube to continuously transform into a high-quality nanotubes of successively smaller diameter, as observed by transmission electron microscope.
Journal ArticleDOI
Probing nanoscale solids at thermal extremes.
Gavi Begtrup,Gavi Begtrup,Keith G. Ray,B. M. Kessler,T. D. Yuzvinsky,T. D. Yuzvinsky,Hernan G. Garcia,Alex Zettl,Alex Zettl +8 more
TL;DR: A novel nanoscale thermal platform compatible with extreme temperature operation and real-time high-resolution transmission electron microscopy is reported, demonstrating that carbon nanotubes are more robust than graphite or diamond.
Journal ArticleDOI
Nanoscale reversible mass transport for archival memory.
TL;DR: A simple electromechanical memory device in which an iron nanoparticle shuttle is controllably positioned within a hollow nanotube channel, allowing application as a nonvolatile memory element with potentially hundreds of memory states per device.
