FibriPy: a software environment for fiber analysis from 3D micro-computed tomography data

Perciano T., Ushizima D., Krishnan H., Sethian J., Lawrence Berkeley National Laboratory, US

Materials characterization using X-ray imaging has enabled development of advanced composites that will open up new opportunities to improve manufacturing. In order to deploy reinforced materials, such as ceramic matrix composites (CMC), several structures must [...]

Development of a new thermally insulating and structural green concrete for lean constructions

Ng S., Jelle B.P., SINTEF, NO

Thermal insulation has always been a demanding requirement in energy efficient constructions, particularly at locations with harsher and more extreme climates. To optimize thermal insulation resistance, new insulation materials and solutions with low thermal conductivity [...]

Effect of Electron Beam Irradiation on the Tensile Properties of Carbon Nanotube Sheets and Yarns

Williams T.S., Miller S.G., Baker J.S., McCorkle L.S., Meador M.A., NASA Glenn Research Center, US

Carbon nanotube sheets and yarns were irradiated using electron beam (e-beam) energy to determine the effect of irradiation dose on the tensile properties. Results showed that there was very little change in the tensile strength [...]

Construction and properties of zein-based cell supports and scaffolds

Padua G.W., Wang Q., Wang Y., Wang Q., Wang Y., University of Illinois Urbana-Champaign, US

Zein, a protein abundant in corn, is capable of self-assembly and may form a variety of structural morphologies (Wang et al 2004, Wang et al 2008a). Zein micro-fibers (Figure 1.), films, and sponges (Figure 2) [...]

Mechanical Properties of Metallized Single Nanofibers

Kim B.S., Kim H-R., Kim H-Y, Kim I.S., Kimura N., Kimura N., Bang H-S., Kim B.S., Kim H-R., Kim H-Y, Kim I.S., Kimura N., Watanabe Y., Kim B.S., Kim H-R., Kim H-Y, Kim I.S., Kimura N., Enomoto Y., Kim B.S., Kim H-R., Kim H-Y, Kim I.S., Kimura N., Shinshu University, JP

Our final goal is to make the metal nanofibers having good properties of metal and explore the mechanical properties of metalized single nanofibers. We are expecting that they would be strong like general metals. In [...]

Development of Melt Blown Electrospinning Apparatus of Isotactic Polyproylene

Watanabe K., Lee K.H., Lee Y.J., Nakamura T., Lee K.H., Lee Y.J., Kim B.S., Kim I.S., Kim K.W., Kim B.S., Kim I.S., Kim K.W., Kim B.S., Kim I.S., Kim K.W., Shinshu University, JP

Melt blown electrospinning is a method of combining melt blown with melt electrospinning. In this study, we developed the multi nozzle melt blown electrospinning machine. The significant point of this method is to use air [...]

Colored nanoparticles:composition and application to protein fibres and hair

Gomes J., Sampaio S., Maia F., University of Minho, PT

The coloration of hair is usually done with dyes that need harsh post treatments with products such as ammonia, so as to have durability. In this work, we have developed nanoparticles (medium range 200 nm), [...]

Electrospun Nanofibrous Membrane Biosensor for lactate

Romero J., Moreno I., González V., Centro deInvestigación en Química Aplicada, MX

Electrospinning is a simple, non mechanical method used to produce non-woven fabrics of ultrafine fibers in the nanometer diameter range (nanofibers).This method is appropriated to obtain high-surface-area polymeric fibrous membranes and is a one-step process [...]
