Nanostructured Single Crystals Sandwiched between Ordered/Disordered Coily and Rod Brushes

Single crystals of poly(ethylene glycol) (PEG)-b-polystyrene (PS), PEG-b-poly(methyl methacrylate) (PMMA), PEG-b-polycaprolactone (PCL), and polyaniline (PANI)-b-PEG-b-PANI were developed from dilute solutions and thin molten films using self-seeding methodology. The PS and PMMA grafted chains were categorized in disordered nano-brushes; however, the PCL and PANI ones were grouped in ordere...

Orientation dependence of the anomalous Hall resistivity in single crystals of Yb14MnSb11

The Hall resistivity, electrical resistivity, and magnetization of single crystals of the tetragonal ferromagnet Yb14MnSb11 are reported as a function of the direction of the current I and magnetic field H with respect to the principal crystallographic axes. With I along the unique c direction and H in the a-b plane, the anomalous Hall resistivity in the limit of zero applied field is negative ...

Ordered, disordered, and coexistent stable vortex lattices in NbSe2 single crystals.

The peak effect (PE) in the critical current density of type II superconductors has been related to an order-disorder transition in the vortex lattice (VL), but its underlying physics remains a controversial issue. Intrinsic to the PE are strong metastabilities that frequently mask the stationary VL configurations. We follow shaking and thermal protocols in NbSe2 single crystals to access these...

Grain Boundary Character Dependence on Nucleation of Discontinuous Precipitates in Cu-Ti Alloys

The dependence of the grain boundary character distribution for a Cu-4 at. % Ti polycrystal alloy (average grain size: 100 µm) on the nucleation of cellular discontinuous precipitates was systematically investigated. In an alloy over-aged at 723 K, cellular discontinuous precipitates consisted of a terminal Cu solid solution and a stable β-Cu₄Ti lamellae nucleated at grain boundaries. Electron ...
