Ferrocene-Containing Optically Active Liquid-Crystalline Side-Chain Polysiloxanes with Planar Chirality

Toralf Scharf

Optically active liquid-crystalline side-chain polysiloxanes have been prepared by grafting planar chiral ferrocene-based vinyl monomers onto commercially available polyhydrosiloxane. Two ferrocene monomers have been synthesized: a linear-type monomer, whi ...

Enantiopure helical (supra)molecular arrays containing lanthanides

Marco Antonio Lama

The diastereoselective synthesis of chiral coordination compounds with d metals proved the effectiveness of the pinene-bipyridine approach in predetermining the chirality at the metal centre. The strong Lewis acidic character of lanthanide cations required ...

Structure and magnetism of atomically thin Fe layers on flat and vicinal Pt surfaces

Klaus Kern, Harald Brune, Stefano Rusponi, Pietro Gambardella, Violetta Sessi

Ultrathin Fe films on Pt substrates have been investigated under ultrahigh vacuum conditions by scanning tunneling microscopy, low energy electron diffraction, magneto-optical Kerr effect, x-ray magnetic circular dichroism measurements, and Kerr microscopy ...

As-doping effect on magnetic, optical and transport properties of Zn 0.9Co0.1O diluted magnetic semiconductor

We report on the structural, magnetic, optical and transport properties of As-doped Zn0.9Co0.1O thin films. X-ray diffraction indicates highly (0 0 0 1) textured samples free of secondary phases. Transmission UV-Vis spectroscopy shows that Co is in the +2 ...

X-ray ferromagnetic resonance spectroscopy

Harald Brune, Giovanni Boero, Radivoje Popovic, Stefano Rusponi, Pietro Gambardella

We present a method to measure continuous-wave ferromagnetic resonance (FMR) spectra based on the core-level absorption of circularly polarized x rays. The technique is demonstrated by using a monochromatic x-ray beam incident on an yttrium-iron-garnet sam ...

Switch peptides

Richard Alan Mimna

Aspects of conformational transitions, folding, and misfolding of peptides and proteins have recently taken center stage in various domains at the interface of chemistry, biology, and medicine because of their impact on protein misfolding diseases. Due to ...

A mass spectrometric and molecular modelling study of cisplatin binding to transferrin

Paul Joseph Dyson, Claire Samantha Allardyce

A combination of mass spectrometry, UV/Vis spectroscopy and molecular modelling techniques hove been used to characterise the interaction of cisplatin with human serum transferrin (Tf). Mass spectrometry indicates that cisplatin binds to the hydroxy functi ...

Self-assembled nanostructures from peptide-synthetic hybrid block copolymers: Complex, stimuli-responsive rod-coil architectures

Harm-Anton Klok

The synthesis, solution and solid state self-assembly properties of a series of polyisoprene-b-poly(ε-benzyloxycarbonyl-L-lysine) PI-b-PZLys and polyisoprene-b-poly(L-lysine) PI-b-PLys block copolymers have been examined. The formation of stimuli-responsiv ...
