Catechol Containing Polyelectrolyte Complex Nanoparticles as Local Drug Delivery System for Bortezomib at Bone Substitute Materials

Martin Guillermo Mueller, Jeremy Pak Hei Wong

The proteasome inhibitor bortezomib (BZM) is one of the most potent anti-cancer drugs in the therapy of multiple myeloma. In this study, an adhesive drug delivery system (DDS) for BZM was developed. Therefore, we extended the present DDS concept of polyele ...

Crowdbreaks: Tracking Health Trends Using Public Social Media Data and Crowdsourcing

Marcel Salathé, Martin Guillermo Mueller

In the past decade, tracking health trends using social media data has shown great promise, due to a powerful combination of massive adoption of social media around the world, and increasingly potent hardware and software that enables us to work with these ...

In-situ strength of individual silicon particles within an aluminium casting alloy

Andreas Mortensen, Goran Zagar, Martin Guillermo Mueller

Measurements of local strength are performed in-situ on individual silicon particles that constitute the second phase of aluminium alloy A356. Particles are shaped using Focused Ion Beam (FIB) milling such that, upon the application of a compressive force ...

Strength and fracture of silicon second-phase particles in aluminium casting alloys

Martin Guillermo Mueller

The mechanical behaviour of metallic materials that have a microstructure composed of a brittle phase embedded in a ductile matrix is dictated by a complex interplay of factors such as local phase properties, cohesive properties, geometrical characteristic ...

Silicon particle pinhole defects in aluminium–silicon alloys

Andreas Mortensen, Martin Guillermo Mueller, Marta Fornabaio

It was recently shown that silicon particles in heat-treated Al–Si casting alloys can contain flaws such as surface pinholes and grooves, which cause varying degrees of reduction in the in situ particle fracture strength and hence influence the mechanical ...

Stable room-temperature micron-scale crack growth in single-crystalline silicon

Andreas Mortensen, Goran Zagar, Martin Guillermo Mueller

Room-temperature fracture along the (111) plane of silicon is probed at the micron-scale using chevron notched cantilever beams that enable stable crack growth before unstable fracture in successful tests. The main experimental observation is that a growin ...

Microscopic strength of silicon particles in an aluminium–silicon alloy

Andreas Mortensen, Goran Zagar, Martin Guillermo Mueller, Marta Fornabaio

A microscopic three-point bending test that measures the strength of faceted particles of high aspect ratio is developed and used to probe individual coarsened plate-like silicon particles extracted from the eutectic Al-12.6%Si alloy. Focused ion beam mill ...

Fracture toughness measurement in fused quartz using triangular chevron-notched micro-cantilevers

Andreas Mortensen, Goran Zagar, Lionel Michelet, Martin Guillermo Mueller, Václav Pejchal

We extend to flat surfaces the fracture toughness method presented in Acts Materialia vol. 86 (2015) p.385 and measure in this manner the fracture toughness of fused quartz. Tests give 0.67 +/- 0.01 MPa m(1/2) which agrees with earlier microscopic and macr ...

Fracture toughness testing of nanocrystalline alumina and fused quartz using chevron-notched microbeams

Andreas Mortensen, Marco Cantoni, Goran Zagar, Martin Guillermo Mueller, Václav Pejchal

We show that chevron-notched samples offer an attractive approach to the measurement of fracture toughness in micron-scale samples of brittle materials and use the method to characterize quartz and nanocrystalline alumina. Focused ion beam milling is used ...

The local strength of microscopic alumina reinforcements

Andreas Mortensen, Marco Cantoni, Goran Zagar, Andreas Rossoll, Martin Guillermo Mueller, Václav Pejchal

We measure, using an adaptation of a method designed for ceramic ball bearings, the local strength of a brittle second phase that serves to reinforce a metal. The method uses focused ion beam milling and a nanoindentation device, and is free of artifacts c ...
