Viscoelastic Contact Resonance Force Microscopy of Polymers in Liquid

Churnside A.B., Tung R.C., Aziz A., Bryant S., Killgore J.P., NIST, US

Contact resonance force microscopy (CR-FM) is an AFM-based technique for quantitatively determining the nanoscale mechanical properties of materials. In CR-FM, the resonant properties of an AFM cantilever in contact with the surface are interpreted as [...]

Applications of Enzymatic Saccharification Residues as a Fully Biobased Adhesive

Hafez I.H., Yang H., Tze W.T.Y., University of Minnesota, US

When woody biomass is enzymatically treated to release from its polysaccharide components fermentable sugars for bio-alcohols and other chemicals production, it typically leaves behind in the waste stream solid residues that are rich in lignin. [...]

Polymer Based Continuous Offset Printing

Mead J., Barry C., University of Massachusetts-Lowell, US

Polymeric materials have tremendous potential for nano and micro-structured products because of their fabrication ease and wide property range. The fabrication processes for polymers are cost-effective and rapid. This work presents novel manufacturing approaches for [...]

Dynamic Nanoindentation Analysis using Generalized Maxwell Model for Viscoelastic Materials Characterization

Yuya P.A., Patel N.G., Clarkson University, US

Nanoindentation has become a very useful tool for materials properties characterization at nanoscale. The Kelvin-Voigt (two-parameter) solid has been used as the conventional model for the tip-sample forces for viscoelastic contact where the sample stiffness [...]

Superhydrophobic and Superhydrophilic Surfaces

Herzog M.B., Johnston J.H., Franzreb M., Victoria University of Wellington, NZ

A new generation of materials possessing a wide range of possible consumer applications such as water harvesting, stain resistant self-cleaning and water-repellent breathable surfaces are being fabricated. Based on nature’s example of the stenocara beetle, [...]

A Novel Technique for Removing Finely Dispersed Particles from Tailings

Ware W., Ashcraft N., Soane D., Soane Energy, US

Traditional oil, gas, and mining industries rely heavily on the use of water as a means to aid in the recovery of natural resources. Often times these activities, either through mechanical shear or chemical additives, [...]

Advanced Biofuel Cell Composed of Highly Modified Electrodes for Biomedical Applications

Leung S.W., Lai J.C.K., Idaho State University, US

A biofuel cell comprised an anode and cathode modified with highly branched polymers, nano Au sol-gel, and reaction specified bioenzymes was constructed. In this study, lactate dehydrogenase (LDH) and glutamate dehydrogenase (GDH) were the enzymes [...]
