Linear micromirror array for broadband femtosecond pulse shaping in phase and amplitude

We are developing a linear array of micromirrors designed for optical, femtosecond laser pulse shaping. It is a bulkmicromachined device, capable of retarding or diminishing certain laser frequencies in order to perform phase and amplitude modulation withi ...

Metals in Proteins: Correlation Between the Metal-Ion Type, Coordination Number and the Amino-Acid Residues Involved in the Coordination

Ivan Dokmanic

Metal ions are constituents of many metalloproteins, in which they have either catalytic (metalloenzymes) or structural functions. In this work, the characteristics of various metals were studied (Cu, Zn, Mg, Mn, Fe, Co, Ni, Cd and Ca in proteins with know ...

Towards the Rational Design of MRI Contrast Agents: Electron Spin Relaxation Is Largely Unaffected by the Coordination Geometry of Gadolinium(III)-DOTA-Type Complexes

Lothar Helm, Alain Borel, Loïck Moriggi

Electron-spin relaxation is one of the determining factors in the efficacy of MRI contrast agents. Of all the parameters involved in determining relaxivity it remains the least well understood, particularly as it relates to the structure of the complex. On ...

Large linear micromirror array for UV femtosecond laser pulse shaping

Nico de Rooij, Jonathan Leon Wolf

We are fabricating a bulk-micromachined micromirror device for laser pulse shaping applications on femtosecond time scales. An array of micromirrors is used to individually retard or diminish certain laser frequencies spanning from the UV to the near-infra ...

Photoluminescent Microporous Lanthanide Silicate AV-21 Frameworks

Philip Pattison

The hydrothermal synthesis and structural characterization of the lanthanide silicate system [Na6Ln2Si12O30x H2O] (Ln=La3+, Sm3+, Eu3+, Gd3+, and Tb3+), named AV-21, has been reported. Structural elucidation of the Sm3+ analogue (isomorphous with the Eu3+, ...

Single-molecule-level characterization of supramolecular systems at surfaces

Dietmar Payer

This thesis deals with the self-organization of individual building blocks, specifically organic molecules and metal atoms, into supramolecular structures on metal surfaces under ultra high vacuum conditions (UHV). Self-organization of supramolecular syste ...

Co(III) complexes of Me-salpn and Me-salbn and the ring size effect on the coordination modes and electrochemical properties: The crystal structures of trans-[Co-III(Me-salpn)(py)(2)]PF6 and cis-alpha-[Co-III(Me-salbn)(4-Mepy)(2)]BPh4 center dot 4-Mepy

Kurt Schenk

The synthesis and characterization of a series of cobalt(III) complexes of the general type Co(N2O2)(L-2) are described. The N2O2 Schiff base ligands used are Me-salpn (H2Me-salpn = N,N'-bis(methylsalicylidene)-1,3-propylenediamine) (1-3) and Me-salbn ...

A reinterpretation of the phase transitions in Na2CO3

Gervais Chapuis, Alla Arakcheeva

Based on the structural data of phases alpha (hexagonal; 756-972 K), beta (monoclinic; 605-751 K), gamma (incommensurate, monoclinic; 295 K) and delta (lock-in, monoclinic; 110 K) of sodium carbonate, Na2CO3, we could draw a parallel between the phase tran ...
