Ordered Structure Pattern on Polymeric Surface

Liu T.H., Huang C-L, Lee S., National Tsing Hua University, TW

The wrinkle pattern on polymeric surface is explained by chemical stresses. We solved the anomalous transport equation to obtain the concentration of solvent in polymeric film. The anomalous transport consists of case I and case [...]

Electrochemical Oxidation of Ammonia Borane on Au-Ag nanoparticles Modified Poly (p-aminophenol) film Glassy Carbon Electrode

Karabi̇beroğlu Ş., Dursun Z., Ege University, TR

In this study, poly (p-aminophenol) film glassy carbon electrode (PPAP/GCE) was prepared by electrochemical polymerization and then Au-Ag nanoparticles created by electrochemical reduction from their solutions on the PPAP/GCE surface by cyclic voltammetry. The surface [...]

Role of Hard Segment Induced Nanosized Domain on Concentrated Solutions and Bulk Properties

Lem K.W., Lee D.S., Haw J.R., Song G.S., Curran S., Sund S., Iqbal Z., Brumlik C., Konkuk University, KR

When a film is cast from solution, the volume fraction of polymer in the film increases with increasing drying temperature and/or time. Its viscoelastic behavior transitions from more viscous (where G” > G’) in dilution [...]

Dry native protein assays on on 3D and 2D substrates by non-contact Laser-Induced-Forward Transfer LIFT process

Genov S., Thurow I., Riester D., Borchers K., Hirth T., Weber A., Tovar G.E.M., University of Stuttgart & Fraunhofer Gesellschaft, DE

To produce nano-scale native protein trehalose patterns on 3D and 2D substrates in constant concentration by Laser-Induced-Forward Transfer (LIFT), ultrathin coatings on LIFT targets are needed [1]. The LIFT process is used as a non-contact [...]

Modeling Sub-Continuum Effects on the Mechanical Properties of Ultrathin Macromolecular Layers

King W.P., Goodson K.E., Stanford University, US

This paper makes progress on the prediction of mechanical modulus and mechanical relaxation time of macromolecular materials at small length and time scales. Fundamental studies of large molecules in confined geometries inform predictions of macroscopic [...]
