Magnetic and in vitro heating properties of implants formed in situ from injectable formulations and containing superparamagnetic iron oxide nanoparticles (SPIONs) embedded in silica microparticles for magnetically induced local hyperthermia

Heinrich Hofmann, Alke Fink, Olivier Jordan

The biological and therapeutic responses to hyperthermia, when it is envisaged as an anti-tumor treatment modality, are complex and variable. Heat delivery plays a critical role and is counteracted by more or less efficient body cooling, which is largely m ...

Neutron spectroscopy measurements and modeling of neutral beam heating fast ion dynamics

Mattia Albergante

The energy spectrum of the neutron emission from beam-target reactions in fusion plasmas at the Joint European Torus (JET) has been investigated. Different beam energies as well as injection angles were used. Both measurements and simulations of the energy ...

A Perching Mechanism for Micro Aerial Vehicles

Dario Floreano, Roland Siegwart, Mirko Kovac, Jürg Markus Germann

Micro Aerial Vehicles (MAVs) with perching capabilities can be used to efficiently place sensors in aloft locations. A major challenge for perching is to build a lightweight mechanism that can be easily mounted on a MAV, allowing it to perch (attach and de ...

Doping a TiO2 Photoanode with Nb5+ to Enhance Transparency and Charge Collection Efficiency in Dye-Sensitized Solar Cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Pascal Comte, Aravind Kumar Chandiran

The optoelectronic properties of our benchmark nanocrystalline anatase TiO2 photoanode were modified by means of aliovalent doping with Nb5+. Even for a low doping level, the charge collection efficiency can be noticeably improved as a result of a higher e ...

Processing of fluorescence angiograms for the quantification of vascular effects induced by anti-angiogenic agents in the CAM model

Hubert van den Bergh, Georges Wagnières, Patrycja Nowak-Sliwinska

The chicken embryo chorioallantoic membrane (CAM) is widely used as an in vivo model to study the vascular effects of angiogenesis modulating agents. The main goal of the present study was to develop and validate a quantitative method to characterize time- ...

A new non-toxic chemically cross-linked ELP hydrogel for in situ protein delivery

Karine Ciapala

Proteins play an essential role in all biological processes and have been attracting more and more attention as drug candidates due to their high specificity and activity. However, their use as therapeutics has been seriously held back given that their abi ...

Experiments in a novel quasi-1D diffusion flame with variable bulk flow

Peter Monkewitz, Etienne Robert

The novel species injector of a recently developed research burner, consisting of an array of hypodermic needles, which allows to produce quasi one-dimensional unstrained diffusion flames has been improved. It is used in a new symmetric design with fuel an ...

Local moderate magnetically induced hyperthermia using an implant formed in situ in a mouse tumor model

Heinrich Hofmann, Alke Fink, Olivier Jordan

Purpose: We investigate a new heat delivery technique for the local treatment of solid tumors. The technique involves injecting a formulation that solidifies to form an implant in situ. This implant entraps superparamagnetic iron oxide nanoparticles (SPION ...
