High-resolution dynamic atomic force microscopy in liquids with different feedback architectures
TL;DR: While the quality factors of dAFM probes may deviate by several orders of magnitude between vacuum and liquid media, their sensitivity to tip–sample forces can be remarkable similar and the reduction in noncontact forces and quality factors in liquids diminishes the role of feedback control in achieving high-resolution images.
Journal ArticleDOI
Nonlinear dynamics of the atomic force microscope at the liquid-solid interface
Daniel Kiracofe,Arvind Raman +1 more
TL;DR: In this article, the nonlinear dynamics of magnetically excited AFM microcantilevers on graphite and mica immersed in deionized water, high-concentration buffers, and methanol are investigated.
Journal ArticleDOI
Nanoscale Characterization of Mock Explosive Materials Using Advanced Atomic Force Microscopy Methods
TL;DR: In this article, the authors used dynamic atomic force microscopy (AFM) techniques to map the local physical properties of mock explosive materials systems, allowing the identification of submicrometer heterogeneities in electrical and mechanical properties that could lead to the formation of hotspots under electromagnetic or mechanical stimuli.
Journal ArticleDOI
The relationship between intermittent limit cycles and postural instability associated with Parkinson's disease
James R. Chagdes,Jessica E. Huber,Meredith Saletta,Meghan Darling-White,Arvind Raman,Shirley Rietdyk,Howard N. Zelaznik,Jeffrey M. Haddad +7 more
TL;DR: The LCO analysis and mathematical model appear to capture the subtle postural instabilities associated with mild PD, and provide insights into the mechanisms that lead to the emergence of unstable posture in patients with PD.
Journal ArticleDOI
Aeroelastic Stability of Axially Moving Webs Coupled to Incompressible Flows
Merrill Vaughan,Arvind Raman +1 more
TL;DR: In this article, the aeroelastic stability of thin flexible web was investigated using an assumed mode discretizarion of an axially moving, uniaxially tensioned Kirchhoff plate coupled with cross and machine direction flows of a surrounding incompressible fluid.
