• Dissolution of Indomethacin Crystals into a Polymer Melt: Role of Diffusion and Fragmentation

  Crystal Growth & Design · 2019-04-22 · 24 citations

  articleOpen access

  The dissolution or melting of a crystalline drug into a molten polymeric matrix underpins the fabrication of a number of drug delivery systems. However, little is known about how crystals dissolve in such viscous matrices. Herein, the heat-induced dissolution of indomethacin crystals into a molten polymer, copovidone, was evaluated, probing changes in crystal features at multiple length scales using various microscopy techniques. Diffusion of the drug into the polymer film was observed by elemen…

• Tactile and Chemical Sensing With Haptic Feedback for a Telepresence Explosive Ordnance Disposal Robot

  IEEE Transactions on Robotics · 2023-06-07 · 18 citations

  article

  Robots can be used to mitigate risks in unsafe and austere settings. In recent years, explosive ordnance disposal robots have reduced the technician's time-on-target, and thus, reduce the direct risk of exposure. This article focuses on the study and development of innovative techniques as the foundational work for a new robot platform. The proposed system includes an organic electrochemical transistor device to detect the existence of explosive residues, and lead to decisions for safe-removal p…

• Ion-Selective Organic Electrochemical Transistor Sensors Using Molecularly Imprinted Polymers

  ACS Applied Polymer Materials · 2022-08-30 · 18 citations

  articleSenior authorCorresponding

  Organic electrochemical transistors (OECTs) have emerged as attractive candidates for biosensing and bioelectronic applications, and they show great potential to serve as compact platforms for ion analysis. OECTs contain electronically active polymer layers whose charge transport properties can be modulated by electrolytes possessing ion concentrations as low as 1 μM. However, standard OECTs typically suffer from a lack of selectivity to electrolyte composition, a prerequisite for viable impleme…

• Toward an Improved Method for Determining the Hamaker Constant of Solid Materials Using Atomic Force Microscopy. I. Quasi-Static Analysis for Arbitrary Surface Roughness

  The Journal of Physical Chemistry C · 2020 · 18 citations

  The initial development and preliminary validation of improvements to an existing approach-to-contact atomic force microscopy (AFM) method for determining the Hamaker constant, A, of solid materials is presented. The updated method explicitly accounts for the surface topography of the given substrate, which will lead to improved estimates of A and extend the range of the types of the surfaces to which the method can be applied. After deriving a general van der Waals (vdW) force expression betwee…
