Admicellar Polymerization Of Calcium Carbonate And Its Performance In Drilling Fluids
… using Fourier Transform Infra-red (FTIR) or Tapping mode Atomic Force Microscopy (AFM). Nevertheless, application testing of low-polymer content admicellar polymerized CaCO 3 in drilling fluids shoincrease in mud viscosity and yield point with improved fluid loss control.

Nano-contact printing of DNA monolayers
… surface coverage was analyzed using tapping mode atomic force microscopy (AFM). The percent coverage of oligonucleotide was then calculated from the tapping mode AFM phase images. Two general trends were found. The oligonucleotide surface coverage on the master increased slightly, …

Synthesis and Characterization of Multiblock Copolymers for Proton Exchange Membrane Fuel Cells (PEMFC)
… block length was longer than 6,000 g/mol (6k). Tapping mode atomic force microscopy (AFM) also showed clear nanophase separation between the hydrophilic and hydrophobic domains and the influence of block length, as one increased from 6k to 10k. Transparent and creasable films were solvent-cast …

Synthesis and Properties of Novel Triptycene-containing Segmented Polyurethanes and Semicrystalline Polysulfone-polyester Multiblock Copolymers
… flexible hard segments with confirmation from tapping mode atomic force microscopy (AFM) and small angle X-ray scattering (SAXS). The flexible HDI can be used to overcome the bulkiness of triptycene, promote microphase separation, and enhance mechanical properties. Novel PTMG based soft …

Cantilever Dynamic Analysis in Tapping Mode Atomic Force Microscopy
Tapping mode atomic force microscopy (AFM) is becoming popular in the area of biology, as well as for polymer and semiconductor materials science. Unlike other AFM techniques, it only makes intermittent contact with the sample, which largely reduces any potential surface damage to soft materials, …

Fundamentals of heat transfer and thermal-mechanical control for improved atomic force microscopy
This dissertation presents novel atomic force microscope (AFM) cantilevers and cantilever technology that improve the measurement rate and precision of AFM. AFM cantilevers with integrated heater-thermometers can generate and sense heat flows to measure and manipulate matter at the nanometer scale. …
