Alginate gel formation on-chip is presented in the first part of this thesis. The technique allows immobilization, and release, of biological cells on-chip. Furthermore, via layer by layer deposition, a locally heterogeneous environment can be generated at ...
This paper presents a brief theoretical discussion on the issue of the wire-grid representation of surfaces using the Numerical Electromagnetics Code (NEC). Different approaches for the determination of the parameters (in particular, the segment radii) of ...
A new hearing therapy called Direct Acoustical Cochlear Stimulation (DACS) was developed and validated in a first clinical trial with four patients. The key component of this therapy based on an implantable hearing device is a micro-actuator that is implan ...
An antenna exhibiting a very wide bandwidth with reconfigurable rejection within the band is presented. The proposed topology is versatile in terms of the number of available antenna states and location of the rejection frequencies, and also allows the ope ...

The literature on gradient and differential microphone arrays makes a distinction between the two types, and nevertheless shows how both types can be used to obtain the same directional responses. A more theoretically sound rationale for using delays in di ...
Typically, the effects of ionic strength on metal adsorption to geosorbents are accounted for by models of the surface electric field, assuming a planar surface. However, bacterial cell walls are not two-dimensional surfaces. Furthermore, electric field mo ...
Based on the results of field-dependent dielectric and magnetic measurements, we observe several interesting behaviors and phase transitions in this geometrically frustrated spinel system CdCr2S4. (1) A glassy dipolar state occurs near T-C similar to 85 K, ...
In this study archaeology, history and palaeoecology (modern and fossil data sets of pollen and non-pollen palynomorphs) were used to reconstruct small-scale pastoral activities in the Pyrenees Mountain during the last two millennia. Modern pollen assembla ...

We report a fundamental study of single cavitation bubbles inside quasi-spherical water drops produced in microgravity (42nd ESA parabolic flight campaign, 8th ESA student parabolic flight campaign). High-speed imaging revealed implications of isolated, fi ...
