Publications related to Phase-locked sustainment of photorefractive holograms using phase conjugation

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Alejandro Dominguez Lopez

We evaluate the Brillouin frequency shift (BFS) determination error when using the Brillouin phase spectrum (BPS) instead of the Brillouin gain spectrum (BGS) in BOTDA setups. We compare the error obtained in the BFS determination in both cases, both with ...

Two-Dimensional Nanoparticle Supracrystals: A Model System for Two-Dimensional Melting

Francesco Stellacci, Jiwon Kim

In a Langmuir trough, successive compression cycles can drive a two-dimensional (2D) nanoparticle supracrystal (NPSC) closer to its equilibrium structure. Here, we show a series of equilibrated 2D NPSCs consisting of gold NPs of uniform size, varying solel ...

Lightfields behind amplitude masks Creating phase discontinuities

Hans Peter Herzig, Toralf Scharf, Wilfried Noell, Myun Sik Kim, Krishnaparvathy Puthankovilakam

Shaping of light fields behind amplitude and phase masks the basis the lithographic structure reproduction. The aerial image or better the intensity distribution defines the resolution of the structure to be printed. Contrast is the main parameter and to a ...

Direct access to macroporous chromium nitride and chromium titanium nitride with inverse opal structure

Weitian Zhao

We report a facile synthesis of single-phase, nanocrystalline macroporous chromium nitride and chromium titanium nitride with an inverse opal morphology. The material is characterized using XRD, SEM, HR-TEM/STEM, TGA and XPS. Interconversion of macroporous ...

Size and Shape-controlled Pd Nanocrystals on ZnO and SiO2: When the Nature of the Support Determines the Active Phase

Lioubov Kiwi, Rocio Micaela Crespo Quesada

The structure sensitivity of acetylene hydrogenation was studied over size-controlled cubic and octahedral Pd nanocrystals (NCs) supported on ZnO and SiO2. Acetylene hydrogenation was found to be structure sensitive [with Pd(111) in octahedra being more ac ...

Phase anomalies in Talbot light carpets of selfimages

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

An interesting feature of light fields is a phase anomaly, which occurs on the optical axis when light is converging as in a focal spot. Since in Talbot images the light is periodically confined in both transverse and axial directions, it remains an open q ...

Manifestation of the spin textures in the thermopower of MnSi

László Forró, Ana Akrap, Stevan Arsenijevic

To identify possible spin texture contributions to thermoelectric transport, we present a detailed temperature and pressure dependence of thermopower S in MnSi, as well as a lowtemperature study of S in a magnetic field. We find that S/T reconstructs the ( ...

Talbot images of wavelength-scale amplitude gratings

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

By means of experiment and simulation, we achieve unprecedented insights into the formation of Talbot images to be observed in transmission for light diffracted at wavelength-scale amplitude gratings. Emphasis is put on disclosing the impact and the interp ...

Thermodynamic study and re-assessment of the Ge-Ni system

Christian Leinenbach, Robert Andrew Watson, Shan Jin

The enthalpies of formation of the intermetallic compounds in the Ge-Ni binary system have been determined by calorimetric measurement and first-principles calculations. Based on the results obtained and information available in the literature, the phase d ...
