The ability to form blends of polymers offers the opportunity of creating a new class of materials with enhanced properties. In addition to the polymer components, recent advances in nanoengineering have resulted in the development of nanosized inorg

In standard diffraction experiments, ensembles of objects are characterized yielding averaged, statistical properties (meaningful only if the ensemble is monodisperse). Focused x-ray beams are used here to localize single nanostructures, identifying

Diffractive optics now plays a major role in optical systems for the extreme ultraviolet and X-ray region. For example, zone plates in their different appearances are widely used for focusing X-rays, as monochromatizing condenser optics, and for high

Multiwall WS2 nanotubes of 40 ‐ 50 nm diameter were functionalized with n-octadecyl phosphonic acid by sonication in toluene and blended with mixtures of polystyrene (PS) and polymethylmethacrylate (PMMA) to form new nanocomposite (NC) materials. T

The two types of X-ray microscopes, scanning and full-field imaging, have different but complementary capabilities in term of image acquisition and spectroscopies. The novel approach used for the first time in the EU RT&D project Twinmic (HPRI-CT-200

Near edge X-ray absorption fine structure (NEXAFS) microscopy has evolved into a powerful characterization tool for polymeric materials. The foundation of this utility depends crucially on the sensitivity of NEXAFS to the specific chemical structure

We have investigated the role of screw dislocations defects in a lyotropic lamellar phase of the mixed DMPC/C12E5/water system using microscopy and scattering techniques. Several of the usual shear-induced orientations of the lamellar phase were obse

A lyotropic system, consisting of a lecithin (DMPC) and a non-ionic surfactant (C12E5) in water was studied. The system exhibits a lamellar-to-nematic phase transition. The nematic phase appears as the temperature is decreased and only exists in a ve

Nanoelectromechanical Systems (NEMS) are among the best candidates to measure interactions at nanoscale [1-6], especially when resonating oscillators are used with high quality factor [7, 8]. Despite many efforts [9, 10], efficient and easy actuation
