Intracellular drug delivery by mesoporous silica nanoparticles (MSNs) carrying hydrophilic and hydrophobic fluorophores as model drug cargo is demonstrated on 2D cellular and 3D tumor organoid level. Two different MSN designs, chosen on the basis of the characteristics of the loaded cargo, were used: MSNs with a surface-grown poly(ethylene imine), ...

Aluminium alloys 7xxx series are widely used in structural components in the aerospace industry as they have high strength at low densities. However, it is well known that in moist-air environments the material fails at lower strengths, and the fracture surface displays macroscopic brittle features attributed to atomic hydrogen, this is known as hy...

In this work, cyclopropylamine (CPA) monomer was plasma-polymerized on poly (ε-caprolactone) nanofiber meshes using various deposition durations to obtain amine-rich surfaces in an effort to improve the cellular response of the meshes. Scanning electron microscopy and X-ray photoelectron spectroscopy (XPS) were used to investigate the surface morph...

[EN] The following work of this Master Thesis is the 4th typology and continues the artistic practice following the idea which I began in the year 2000 in Estonia. This body of work is an artistic view of the dress as a sculptural form using unusual materials. The material is a communicator, like a language. The aim of this Master Thesis is to exte...

[EN] The project tries to think over, through painting, about the personal and subjective experience around daily life and its perception. Visual culture and the media as paradigms that invade all fields of experience and social relations take on a primary importance in the way of facing artistic creation. From the production of pictorial and graph...

Dye coating techniques for colored materials are often cost intensive or cause degradation of the material during processing. Here the authors demonstrate a fast, scalable and cost efficient plasma dye coating procedure, which allows for covalent immobilization of dye molecules on different polymer surfaces.

We investigate the effect of gamma radiation on flux grown KTiOPO4 and Rb:KTiOPO4 samples, as well as their periodically poled variants. Specifically, we study the altered transmission due to color-center formation via gamma irradiation. We measured the transmission of our samples for varying radiation doses and demonstrate effective temperature an...

A new multipactor saturation mechanism is presented for high power microwave devices in the presence of dielectrics. Recent measures have shown that the positive charge deposited on a dielectric as a consequence of the secondary electron emission causes the reduction of its secondary electron yield. This work shows a new multipactor dynamics within...

The interaction between lightning arcs and composite materials is a challenging issue for maintenance and safety considerations in the aerospace industry [1]. Composite materials exhibit a much lower conductivity than metallic materials, as well as an important anisotropy due to the orientation of the fibres and the insulating nature of the matrix....

A martensitic gear steel (18CrNiMo7-6) was annealed at 180 degrees C for 2h and at similar to 750 degrees C for 1h to design two different starting microstructures for shot peening. One maintains the original as-transformed martensite while the other contains irregular-shaped sorbite together with ferrite. These two materials were shot peened using...
