Polymers play a central role in shaping our world across various fields, but their heavy reliance on petrochemicals poses climate change, environmental and health risks. To address and alleviate these issues, transitioning to sustainable polymers, sourced ...

Polymer brushes, which are polymers anchored to a solid substrate by one chainend, have the ability to modify the properties of an underlying substrate, offering intriguing features such as enhanced lubrication, reduced friction, colloidal stability, and a ...

Seeded emulsion polymerization is one of the best-known methods for preparing polymer particles with a controlled size, composition, and shape. It first requires the preparation of seed particles, which are then swollen with additional monomer (the same as ...

The appearance of objects is governed by how they reflect, transmit and absorb the light they receive. That, in turn, depends on the material's internal structure, surface structure, and viewing and illumination directions. Changes in those characteristics ...

Disordered packings of colloidal spheres show angle-independent structural color when the particles are on the scale of the wavelength of visible light. Previous work has shown that the positions of the peaks in the reflectance spectra can be predicted acc ...

Relatively weak red photoluminescence of carbon dots (CDots) is a major challenge on the way to their successful implementation in biological and optoelectronic devices. We present a theoretical analysis of the interaction among the surface emission center ...

Phase separation of immiscible fluids is a common phenomenon in polymer chemistry, and is recognized as an important mechanism by which cells compartmentalize their biochemical reactions. Biomolecular condensates are condensed fluid droplets in cells that ...

A new conducting polymer poly (3, 4-phenylenedioxythiophene) is synthesized by the electrochemical polymerization technique with different solvents. We find that solvents used in electrochemical polymerization play important roles for the catalytic activit ...

Chain-end-labeled polymers are interesting for a range of applications. In polymer nanomedicine, chain-end-labeled polymers are useful to study and help understand cellular internalization and intracellular trafficking processes. The recent advent of fluor ...

The theme of this thesis revolves around three important manifestations of light, namely its corpuscular, wave and electromagnetic nature. Our goal is to exploit these principles to analyze, design and build imaging modalities by developing new signal proc ...

A device for self-tracking a light source, including a focusing optical device configured to focus incoming light to a focal spot, an adaptive device configured to reflect the light of the focal spot and arranged to provide for a phase change at an area of ...

Controlled radical polymerization techniques such as RAFT allow fine control over polymer molecular weight and architecture. These techniques, however, do not eliminate compositional drifts in copolymerizations, which are the consequence of differences in ...

The surface chemistry at the DNA recognition and binding interface plays an important role in determining the performance of DNA microarrays and DNA biosensors. Surface-initiated controlled radical polymerization (SI-CRP) reactions represent a powerful too ...

The appropriate choice of glazing in a facade depends on many factors. They include amongst other criteria: location, orientation, climatic condition, energetic efficiency, usage of the building, required user comfort, and the architectural concept. On the ...

The invention refers to a method for analysing reflected light of an object. First a light angle distribution for a point of the object is determined. Then a plenoptic projector is controlled to illuminate the point of the object with the determined light ...

Surface-initiated polymerization represents a versatile strategy to modify a diverse range of materials with thin, functional polymer coatings. While in many cases the desired functional groups can be directly incorporated via (co)polymerization of the app ...

We report on the modeling of a photopolymerizable hydrogel and its application as a replacement of the interior of the intervertebral disc (so called Nucleus Pulposus). The hydrogel is initially injected in its liquid form and then photopolymerized via a s ...

The achievement of high ionic conductivity in single-ion conducting polymer electrolytes is one of the important aims for various electrochemical devices including modern lithium batteries. One way to enhance the ionic conductivity in polyelectrolyte syste ...

Previously we reported emulsion polymerization of propylene sulfide with Pluronic F127 as an emulsifier, yielding nanoparticles (NPs) in the 25 nm size range. Immunologically functional NPs were prepared by adding an antigen Pluronic conjugate to the polym ...

The development of innovative bioanalytical technologies that enable the discovery of new therapeutics or the creation of systems for rapid, accurate and parallel analyses has gained an extraordinary interest in the biomedical sector in the last 10-15 year ...
