Strain and Magnetoresistance Anisotropy of PR0.7SR0.3MNO3 Ultrathin Films
Recently, the doped manganese oxides have been the focus of intensive research due to the remarkable colossal magnetoresistance (CMR) effect observed in the system [1, 2, 3, 4]. The manganites are perovskite o...

A constitutive model of multiphase mixtures and its application in shearing flows of saturated solid-fluid mixtures
A continuum theory of a multiphase mixture is formulated. In the basic balance laws we introduce an additional balance of equilibrated forces to describe the microstructural response according to Goodman & Co...

Stability of polymer films as a 2D system
According to classical theory of phase transition, fluctuations in systems with low dimensions are so violent that the phase boundary between unstable and metastable states would be smeared. In this experiment...

Confined viscous liquids: Interfacial versus finite size effects
Confining a supercooled liquid to spaces of several nanometer in diameter can lead to dramatic changes in the relaxation dynamics of the material. In many cases, the effect is reported as a confinement induced...

Determining particulate–solid interphase strength using shear-induced anisotropy
The resistance to shear deformation developed by a granular material layer in contact with a topographically rough natural or manufactured solid material surface is critical to the stability of a variety of co...

An RF quadrupole–time-of-flight system for isobar-separation and multiplexed low-energy Rare-Isotope Beam experiments
A novel system consisting of RF quadrupole and time-of-flight sections is proposed, in which ions can be cooled, bunched, mass separated with a resolution sufficient to differentiate between isobars, and gu...

Attenuation in sand: an exploratory study on the small-strain behavior and the influence of moisture condensation
The loss mechanisms responsible for the observed attenuation in soils are often unclear and controversial. This is particularly the case with the small-strain dam** D min in air-dry sand...
