FRP-balsa composite sandwich bridge deck with complex core configuration

Thomas Keller, Anastasios Vassilopoulos, Julia De Castro San Roman Fest, Michael Osei-Antwi

The aim of this work was to investigate to what extent the performance of a glass fiberreinforced polymer (GFRP) sandwich slab-bridge with uniform high-density balsa core could be improved in terms of structural efficiency and weight thanks to a more compl ...

Hydrophobic Meshes for Oil Spill Recovery Devices

Francesco Stellacci

Widespread use of petrochemicals often leads to accidental releases in aquatic environments, occasionally with disastrous results. We have developed a hydrophobic and oleophilic mesh that separates oil from water continuously in situ via capillary action, ...

Investigation of pollution sources in rivers using passive sampling: a discussion based on in-situ experiments on PCBs

Luiz Felippe De Alencastro, Nicolas Estoppey, Julien Omlin

Tools able to investigate pollution sources at low cost are urgently needed to achieve the requirements of the Water Frame Directive and international treaties (such as the Stockholm Convention) which are to reduce, or even cease, pollution emissions to wa ...

A theoretical quantification of the possible improvement in the mechanical properties of carbon nanotube bundles by carbon ion irradiation

William Curtin

Improvement of single wall carbon nanotube (CNT) bundle mechanical properties through carbon ion irradiation is investigated using molecular dynamics. Increased inter-tube shear and toughness properties through formation of inter-tube cross-links is balanc ...

Importance of polyethylene thickness in total shoulder arthroplasty: A finite element analysis

Dominique Pioletti, Alexandre Terrier, Alain Farron, Vittoria Brighenti

Background: Articular surfaces reconstruction is essential in total shoulder arthroplasty. Because of the limited glenoid bone support, thin glenoid component could improve anatomical reconstruction, but adverse mechanical effects might appear. Methods: Wi ...

Carbon nanotubes-SU8 composite for flexible conductive inkjet printable applications

Jürgen Brugger, László Forró, Arnaud Magrez, Richard Gaal, Marijana Mionic Ebersold, Kristopher Pataky

We have developed a conducting composite based on multi-walled carbon nanotubes and bisphenol A novolak epoxy resin (SU8) for inkjet printing purposes. We could deposit regular conducting stripes and arrays of 150 mu m spots on glass and on flexible polyet ...
