Recent developments in material science and manufacturing have strongly increased the freedom that engineers can enjoy when designing structures and components. By controlling material distribution at the micro- and meso-scale metamaterials are designed which can have extraordinary properties like negative elastic modulus, electromagnetic and acoustic band gaps or super-hydrophobic surfaces. At the same time micro-electro-mechanical systems (MEMS) allow for the creation of extremely small and sophisticated machines and mechanisms. This category also contains past and current studies on nanotechnology.
Vitamin protection08 Sep 2017
Vitamin protection08 Sep 2017 The next goal in manned spaceflight of bringing humans to Mars will add a new and exciting step to the history of human spaceflight with regard to the travel distance and duration. This interplanetary mission presents many unique challenges from the technical, psychological and physiological point of view that need to be addressed prior to the l...

Auxetic materials08 Sep 2017 Composite materials are increasingly used for applications in space, aerial and maritime vehicles. A promising class of materials are auxetic materials with a negative Poisson’s ratio.
Microwave Drill21 Nov 2014
Microwave Drill21 Nov 2014 The study of the subterranean composition of planets is an important tool for understanding the history and evolution of our solar system. In the investigation of the composition of Lunar, Mars and even asteroid surfaces, mechanical drills are currently being used in a variety of robotic explorers (NASA Curiosity, ExoMars, Rosette/Philae).
Vibration isolation using acoustic band gaps and negative stiffness23 Apr 2013 Vibrations are often an undesired phenomenon. Here we try to develope an efficient, passive vibration isolation even at low frequencies by combining the principles of acoustic band gaps and negative stiffness mechnisms.

Seismology of rubble pile asteroids01 Oct 2012
Seismology of rubble pile asteroids01 Oct 2012 Can we deduce the internal composition of the asteroid (particle size, particle density, etc.) from the spectrum of eigenvalues?
Control of thermal emissivity01 Sep 2010
Control of thermal emissivity01 Sep 2010 The thermal control in a spacecraft is a key issue in space engineering. On Earth the thermal control of a system can be controlled by means of the conduction, convection and radiation mechanism. However in space only the latter is available due to the characteristic high vacuum of this environment. Thus, it is of great interest to develop new m...
Transport of nanostructured material in the interplanetary medium01 Sep 2010 The main problem we want to address in this project is related to the transport of material between two different orbits in an interplanetary environment. One possible approach is using a spacecraft to transport a given amount of material. This conservative approach presents several shortcomings in terms of costs, risks, etc. As an alternative, ...
New devices based on Metamaterials01 Sep 2010
New devices based on Metamaterials01 Sep 2010 Metamaterials could be considered as being the latest revolution within the Electrical and Electronic Engineering community. The control over the material properties is traditionally achieved by the chemical combination of different compounds in such a way that a different substance is obtained. Stainless steel, teflon or kevlar among many other...
