Towards implementing new isotopes for environmental research:Redetermination of the 32Si half-life

The predicted climate changes on Earth will significantly impact the environment and human society. The climate patterns observed during the past centuries led to a better understanding of the driving forces for such changes. However, more studies using ne ...

Rare Earth and Bimetallic Transition Metal Islands at Surfaces

Dimitrios Mousadakos

This thesis reports on the growth and on the magnetic characterization of nanostructures made of 3d-4d transition metals and rare earths. In all the experiments the nanostructures have been grown by atomic beam epitaxy (ABE) in ultra high vacuum conditions ...

Development of X-Ray Powder Diffraction Methods for Biomolecules

Sebastian Basso

The comparable order of magnitude between interatomic distances in a crystal and the wavelength of X-rays make X-ray crystallography the ideal analytical tool to gain insight into the structure of crystalline material, including biomolecules. Nevertheless, ...

First-Principles Study of the High-Temperature Phase of Li

Michele Ceriotti, Giacomo Francesco Leonardo Miceli, Michele Parrinello

On the basis of ab initio molecular dynamics simulations, we propose that the Fm3̄m symmetry of the high-temperature (above 356 K) phase of Li 2NH results from dynamical disorder due to fast diffusion of Li interstitials and a slower diffusion of Li vacanc ...

The incommensurately modulated structures of natural natrite at 120 and 293 K from synchrotron X-ray data

Gervais Chapuis, Alla Arakcheeva, Philip Pattison

The incommensurately modulated structure of the mineral natrite has been refined for the first time. Two single-crystal grains, Lv and Kh, from two different occurrences [Mt. Karnasurt, Lovozero massif (Lv), Kola peninsula, Russia, and the pegmatite of Mt. ...

Photorefractive properties of lithium niobate crystals doped with manganese

Demetri Psaltis

The photorefractive properties of lithium niobate crystals doped with manganese (Mn) have been investigated. It is found that the effect of dark decay due to electron tunneling, which is the limiting factor of the highest practical doping level, is less in ...

Photorefractive recording in LiNbO3 : Mn

Demetri Psaltis

The dynamic range, sensitivity, and dark decay of holographic recording of wavelength 458 nm in LiNbO3 crystals doped with 0.2-at. % Mn with different oxidation states have been measured. The measured sensitivity is 0.5 cm/J and is found to be independent ...

Refractory calcium-aluminum-rich inclusions and aluminum-diopside-rich chondrules in the metal-rich chondrites Hammadah al Hamra 237 and Queen Alexandra Range 94411

Anders Meibom

The metal-rich chondrites Hammadah al Hamra (HH) 237 and Queen Alexandra Range (QUE) 94411, paired with QUE 94627, contain relatively rare (

Forsterite-rich accretionary rims around calcium-aluminum-rich inclusions from the reduced CV3 chondrite Efremovka

Anders Meibom

It was suggested that multilayered accretionary rims composed of ferrous olivine, andradite, wollastonite, salite-hedenbergitic pyroxenes, nepheline, and Ni-rich sulfides around Allende calcium aluminum-rich inclusions (CAIs) are aggregates of gas-solid co ...
