MWCNTS Production by Means of Pyrolysis of Polyethylene-Terephtalate in a Bubbling Fluidized Bed

Mastellone M.L., Arena U., Second University of Naples, IT

A bubbling fluidized bed reactor having 102mmID and realised in AISI 316L stainless steel has been used as pyrolyser under different operating conditions. The reactor has been operated at fixed fluidising velocity (U=0.16m/s) and at [...]

Development of a novel material for reversible hydrogen storage

Titus E., Coelho M.C., Cabral G., Madaleno J.C., Shokuhfar T., Gracio J., University of Aveiro, PT

An efficient hydrogen storage material is a hot topic of discussion among modern scientific community worldwide. The efficiency of the hydrogen storage material is measured on the basis of their adsorption enthalpy. Low adsorption enthalpy [...]

Advanced CryoTEM and Tomography for Two- and Three-Dimensional Nano-Characterisation of Soft Matter

Sourty E., de Haas F., Frederik P.M., Frederik P.M., Loos J., Stokes D.J., Hubert D.H.W., FEI Company, NL

Recent advances in transmission electron microscopy (TEM) mean that we are able to achieve unprecedented resolution at the atomic level. Furthermore, improved methods for obtaining and reconstructing tilt series projections allow us to create high [...]

Understanding and utilizing molecular constraints in nanoscale material designs

Sills S., Overney R.M., Micron Technology, Inc., US

Challenges regarding nanoscale material designs often arise from the collision of two sets of critical length-scales; namely, device dimensions approach the length scale of molecular-level processes. On one hand, these finite size constraints cannot be [...]

MEMS Humidity Structure with Cantilever – Simulation of Behaviour

Suchanek P., Husak M., Czech Technical University in Prague, CZ

The aim of this paper is to report the design of the simple polymers structure humidity sensors and its mechanical and piezorezistive simulation in CoventorWare. Acquired simulation data gets a primary image about sizes bend [...]

A compact, low-power cantilever-based sensor array for chemical detection

Loui A., Ratto T.V., Wilson T.S., Mukerjee E.V., Hu Z-Y, Sulchek T.A., Hart B.R., Lawrence Livermore National Laboratory, US

A compact and low-power cantilever-based sensor array has been developed and used to detect various vapor analytes. This device employs sorptive polymers that are deposited onto piezoresistive cantilevers. We have successfully detected several organic vapors, [...]

Favored Osteoblast Interactions with Aerosol Printed 3D Nano-to-Macro Hierarchical Architectures: The Promise of Nanocomposites as Orthopedic Prostheses

Liu H., Webster T.J., Brown University, US

Ceramic/polymer nanocomposites simulate bone in terms of its nanostructure and associated properties, thus, offering a promising new opportunity for bone regeneration in a natural way. Previous in vitro studies demonstrated that well-dispersed nanophase titania in [...]
