Acid Electrolytes Effect on In-Situ Growth and Morphology of Polymer Nanowires in Microelectrode Devices

Mushfiq M., Alam M.M., InnoSense LLC, US

Conductive polymer (CP)-based nanostructured materials in thin films and nanowires have been utilized in numerous chemical sensor and biosensor applications.(1) Their beneficial attributes include: lightweight, large surface area, adjustable transport properties, chemical specificity, low cost, [...]

Surface Modification and Characterization of Polylactic Acid (PLA) 3D printed structures for Cell culture applications.

Pokharna P., Ghantasala M., Rozhkova E., Western Michigan University, US

The main aim of this research is to understand the surface modification effects and improve the surface properties of 3D printed scaffolds that would be biocompatible and support the growth and proliferation of cells. Polylactic [...]

Nano-JKR Method Eliminates Adhesion Errors in Nanoindentation of Compliant Polymers and Hydrogels

Ebenstein D.M., Bucknell University, US

Although nanoindentation (or instrumented indentation) was originally developed for characterization of hard, stiff materials such as metals and silicon, this tool has recently seen increased use with compliant polymers and hydrogels. One challenge associated with [...]

Abrasive scanning with AFM on biocompatible polymers: measuring dry vs. swollen film thickness and probing properties

Haugstad G., Wormuth K., University of Minnesota, US

Atomic force microscopy (AFM) is well-known as a tool for imaging surface topography down to subnanometer scales on all forms of matter, utilizing a scanning stylus (“tip”). The method is applicable to biomolecules adsorbed to [...]

Characterization of Polymer Nanocomposites with Thermal Analysis and Spectrum techniques

Mena Navarro M.E., Estrada Guerrero R.F., Torres González L.A., Tinajero R., Palafox L., Universidad Iberoamericana Ciudad de Mexico, MX

Polymer nanocomposites have attracted attention in materials science because they exhibit different properties from those of their counterpart polymer microcomposites. An important characteristic is the size of nanoparticles, their effects increase because of their scattering [...]

Effect of filler size in a graphene-anthracene carbon-carbon composite

Singh M., Vander Wal R., Pennsylvania State University, US

Characterizing carbon-carbon composite behavior across multiple length scales is essential to comprehending its macro-scale behavior. This work characterizes a graphene-anthracene composite from the nano- to the micron-scale with a variety of analytical techniques brought to [...]

Thorough Characterization of Liposomes by Complementary Light and X-Ray Scattering Techniques

Ragheb R., Bolze J., Taylor G., Tamaddoni N., Griffiths D., Nobbmann U., Malvern Panalytical, US

Liposomes are spherical vesicles with an aqueous core enclosed by one or more phospholipid bilayers or lamellae and are frequently classified based on their size and number of bilayers [1]. They are often used in [...]

Ultra Uniform Colloidal Particles as Nanoscale Reference Materials

Saunders A.E., Garcia D.A., Oldenburg S.J., nanoComposix, Inc., US

The ability to understand and predict the properties of nanomaterials relies on an accurate measurement of their size, shape, number density, and other physical properties. One challenge associated with many measurement techniques is the lack [...]
