H+ implanted channel waveguides in buried epitaxial crystalline YAG:Nd, Tm layers and infrared-to-blue upconversion characterization

Nd, Tm:YAG codoped single crystal waveguides were studied in order to discover if the presence of Nd3+ ions favors blue luminescence at 486 nm. Innovative implantation techniques were applied to locally change Delta n and form varied H+ implanted channel s ...

Molecular basis of histone H3K4me3 recognition by ING4

The inhibitors of growth (ING) family of tumor suppressors consists of five homologous proteins involved in chromatin remodeling. They form part of different acetylation and deacetylation complexes and are thought to direct them to specific regions of the ...

A thermodynamic and experimental study of the conditions of thaumasite formation

Karen Scrivener, Barbara Lothenbach, Thomas Schmidt

The formation of thaumasite was investigated with the progressive equilibrium approach (PEA). This approach experimentally simulates the conditions of various levels of sulfate addition in hardened cement pastes. The influence of limestone, time, C(3)A con ...

Nature an architectural approach. The school and why perception matters. A primary school in Zurich West

Aline Dubach

If we assume that architecture is the art of replacing our immediate surroundings, the designed or constructed space has something in common with nature: it assumes the role of something that surrounds us as a whole. Space is something we perceive and sens ...

Divalent Metal Nanoparticles

Francesco Stellacci

Nanoparticles can be used as the building blocks for materials such as supracrystals or ionic liquids. However, they lack the ability to bond along specific directions as atoms and molecules do. We report a simple method to place target molecules specifica ...

Some linear and nonlinear problems involving differential forms

Saugata Bandyopadhyay

In this thesis, we study some linear and nonlinear problems involving differential forms. We begin by studying the problem of pullbacks which asks the following question: for two given differential forms, if one is the pullback of the other via a diffeomor ...

Multiple magnon modes and consequences for the Bose-Einstein condensed phase in BaCuSi2O6

Henrik Moodysson Rønnow, Bruce Normand, Christian Rüegg

The compound BaCuSi2O6 is a quantum magnet with antiferromagnetic dimers of S=1/2 moments on a quasi-2D square lattice. We have investigated its spin dynamics by inelastic neutron scattering experiments on single crystals with an energy resolution consider ...
