Autonomous oil flow generated by self-oscillating polymer gels

Vito Cacucciolo

The previously reported gel and polymer actuators require external inputs, such as batteries, circuits, electronic circuits, etc., compared with autonomous motions produced by the living organisms. To realize the spontaneous motions, here, we propose to in ...

Printing on liquid elastomers

Pedro Miguel Nunes Pereira de Almeida Reis, Pierre-Thomas Paul Brun

In recent years the research community has paid significant attention to geometrically engineered materials. These materials derive their unique properties from their structure rather than their chemistry alone. Despite their success in the laboratory, the ...

Healing of a glass fibre reinforced composite with a disulphide containing organic-inorganic epoxy matrix

Véronique Michaud, Amaël Maximilien Cohades, Wouter Post

We report the development of an intrinsic healing glass fibre reinforced polymer (GFRP) composite based on a disulphide-containing organic-inorganic thermoset matrix. Thermomechanical experiments showed that the newly developed matrix has a combination of ...

Sensitivity and resistance of soil fertility indicators to land-use changes: New concept and examples from conversion of Indonesian rainforest to plantations

Thomas Guillaume

Tropical forest conversion to agricultural land leads to a strong decrease of soil organic carbon (SOC) stocks. While the decrease of the soil C sequestration function is easy to measure, the impacts of SOC losses on soil fertility remain unclear. Especial ...

Advanced Materials Enabling High-Volume Road Transport Applications of Lightweight Structural Composite Parts

Véronique Michaud, Ignaas Herman Johannes Verpoest

Current applications of carbon fibre reinforced plastics (CFRP) can be found mostly in sectors where their use is not principally cost-driven and which have limited production volumes, such as aerospace and sports cars. In order to achieve a step-change in ...

Integrated active tracking detector for MRI-guided interventions

Giovanni Boero, Jens Anders, Paul Sangiorgio

We present a fully integrated detector suitable for active tracking of interventional devices in MR-guided interventions. The single-chip microsystem consists of a detection coil, a tuning capacitor, an intermediate frequency downconversion receiver, and a ...

Small strain mechanical properties of latex-based acrylic nanocomposite films

John Christopher Plummer, Riccardo Ruggerone

A waterborne latex-based technique has been used to prepare acrylic films with laponite contents up to about 25 vol%. The laponite was attached to the surfaces of the latex particles, giving a cellular arrangement of laponite-rich regions at high laponite ...

Evaluation of residual strains in epoxy with different nano/micro-fillers using embedded fiber Bragg grating sensor

John Botsis, Marco Lai, Klaus Friedrich

The Influence of SiO2 nanoparticles and rubber micro-fillers on the mechanical and thermal responses of an epoxy based composite is investigated using classical quantitative thermo-mechanical testing (tensile tests DMTA TMA) microstructural analysis (Micro ...

Highly filled polymer nanocomposite films derived from novel nanostructured latexes

Riccardo Ruggerone

The overall aim of this thesis has been to assess the potential of latex-based technologies for the preparation of polymer/clay nanocomposites. The key feature of latex-based technologies is that they offer the possibility of improved control of the final ...

Carbon outclasses wood in racket paddles: Ratings of expert and intermediate tennis players

Michael Herzog, Olaf Blanke, Véronique Michaud, Christian Fischer

Wooden racket paddles were modified with rubber and carbon fibre laminates and their differences tested in terms of flexural, damping, and coefficient of restitution properties. Four rackets types were designed: a wood reference, wood with rubber, carbon f ...

Assessing the Role of Poly(ethylehe glycol-bl-propylene sulfide) (PEG-PPS) Block Copolymers in the Preparation of Carbon Nanotube Biocompatible Dispersions

Davide Demurtas, Jeffrey Alan Hubbell, Conlin O'Neil

Amphiphilic block copolymers based on hydrophobic polysulfides (poly(propylene sulfide), PPS) and hydrophilic polyethers (poly(ethylene glycol), PEG) have been used to solubilize and disperse single-walled carbon nanotubes (SWNTs). The obtained highly conc ...

Fracture mechanisms in polystyrene/laponite nanocomposites prepared by emulsion polymerization

John Christopher Plummer, Riccardo Ruggerone

Transmission electron microscopy (TEM) has been used to investigate the effect of laponite clay on microdeformation in thin latex-based polystyrene (PS) films, in which the laponite was concentrated at the original interfaces between the PS particles. At r ...
