The segmentation of cerebral aneurysms is a challenging task because of their similar imaging features to blood vessels and the great imbalance between the foreground and background. However, the existing 2D segmentation methods do not make full use of 3D information and ignore the influence of global features. In this study, we propose an automati...
Silicon photonic devices are very sensitive to process variation, and it is important for circuit designers that they can predict the effect of this variability during the design phase, and optimize their design for both performance and yield. This requires an accurate predictive model of the spatial variations induced by the fabrication process. W...
Acrylate-endcapped urethane-based precursors constituting a poly(D,L-lactide)/poly(epsilon-caprolactone) (PDLLA/PCL) random copolymer backbone are synthesized with linear and star-shaped architectures and various molar masses. It is shown that the glass transition and thus the actuation temperature could be tuned by varying the monomer content (0-8...
Quantum dots (QDs) are semiconductor nanocrystals that are used in optoelectronic applications. Most modern QDs are based on toxic metals, for example Cd, and do not comply with the European Restriction of Hazardous Substances regulation of the European Union. Latest promising developments focus on safer QD alternatives based on elements from the I...
An important challenge in the valorization of CO2 and H2 into fuels is the development of a stable, reusable and easy to handle heterogeneous catalyst. Here, a silica nanofibrous membrane is investigated as carrier for Ru nanoparticles, themselves encapsulated inside the metal organic framework (MOF) Cr-MIL-101. The catalytic membrane is investigat...

Diffractive optical elements (DOEs) are increasingly used as lightweight and compact solutions in photonic devices. Steering of light and manipulation of the polarization can be efficiently obtained with the help of photo-aligned liquid crystal (LC) devices. 1D LC diffraction gratings are studied that are based on the geometric phase principle and ...

The self-assembling behavior of peptides and derivatives is crucial in the natural process to construct various architectures and achieve specific functions. However, the surface or interfacial self assembly, in particular, on the surface of micro-or nanoparticles is even less systematically investigated. Here, uniform porous CaCO3 micro particles ...
