In this report single-wall carbon nanotubes (SWNTs) were coated onto latex using spray coating to produce a stretchable electrode. The electrochemical properties of the electrode were determined using cyclic voltammetry and electrochemical impedance spectroscopy and galvanostatic charge/discharge tests were also carried out. The impedance and charge/discharge curves of the latex/SWNTs electrode showed good capacitive behavior even after repetitive stretching to 100% strain. The highest capacitance value obtained for the unstretched SWNTs electrode was 119 F gā1 in 1 M Na2SO4 at 5 mV sā1. After the 100th stretch ā 80% of the original capacitance value was retained.
Fluidic Automation Of Nitrate And Nitrite Bioassays In Whole Blood By Dissolvable-Film Based Centrifugo-Pneumatic Actuation, Charles E. Nwankire, Di-Sien S. Chan, Jennifer Gaughran, Robert Burger, Robert A. Gorkin Iii, Jens Ducree
Fluidic Automation Of Nitrate And Nitrite Bioassays In Whole Blood By Dissolvable-Film Based Centrifugo-Pneumatic Actuation, Charles E. Nwankire, Di-Sien S. Chan, Jennifer Gaughran, Robert Burger, Robert A. Gorkin Iii, Jens Ducree

This paper demonstrates the full centrifugal microfluidic integration and automation of all liquid handling steps of a 7-step fluorescence-linked immunosorbent assay (FLISA) for quantifying nitrate and nitrite levels in whole blood within about 15 min. The assay protocol encompasses the extraction of metered plasma, the controlled release of sample and reagents (enzymes, co-factors and fluorescent labels), and incubation and detection steps. Flow control is implemented by a rotationally actuated dissolvable film (DF) valving scheme. In the valves, the burst pressure is primarily determined by the radial position, geometry and volume of the valve chamber and its inlet channel and can ā¦

Printing food seems more like an idea based in Star Trek rather than in the average home. But recent advances in 3D printing (known formally as additive manufacturing) are driving the concept closer to reality. With everything from printed metal airplane wings to replacement organs on the horizon, could printed food be next? And how will we feel when it's served at the table?

The mechanical characteristics of ionic-covalent entanglement hydrogels consisting of combinations of the biopolymers gellan gum and kappa-carrageenan, and the synthetic polymers polyacrylamide and an epoxy amine were investigated. Compression testing showed that these gels exhibited "double network" behavior, i.e. strong tough gels.

Here, we show that graphene oxide (GO) dispersions exhibit unique viscoelastic properties, making them a new class of soft materials. The fundamental insights accrued here provide the basis for the development of fabrication protocols for these two-dimensional soft materials, in a diverse array of processing techniques.
