, 1998 We study the combined effect of temperature and disorder in the spacer on the interlayer exchange coupling. The temperature dependence is treated on ab initio level.

On the damped oscillations of an elastic quasi-circular membrane in a two-dimensional incompressible fluid [PDF]
, 2014 We propose a procedure - partly analytical and partly numerical - to find the frequency and the damping rate of the small-amplitude oscillations of a massless elastic capsule immersed in a two-dimensional viscous incompressible fluid. The unsteady Stokes

MetalMat, EarlyView.ABSTRACT Machining of materials is an invaluable technique to give specific shapes and dimensions of desired materials. Different machining processes give rise to different surface characteristics that include not only surface roughness but also specific surface morphology, such as the recast layer.

Polymer Composites, EarlyView.Application of the fiber bundle cell model for design or prediction of pseudo‐ductility. ABSTRACT In this study, we developed and validated a novel fiber bundle cell (FBC) framework to enable rapid, reliability‐anchored design of pseudo‐ductile thin‐ply carbon/glass hybrid composites.

Mechanism for Spontaneous Growth of Nanopillar Arrays in Ultrathin Films Subject to a Thermal Gradient [PDF]
, 2010 Several groups have reported spontaneous formation of periodic pillar-like arrays in molten polymer nanofilms confined within closely spaced substrates maintained at different temperatures.

Small, EarlyView.Pulse‐duration‐controlled ultra‐short laser processing is shown to directly create binder‐free Fe‐enriched NiOx electrodes with tunable porosity, active‐site density, and oxygen‐evolution kinetics. Shorter pulses generate defect‐rich nanostructures that accelerate charge transfer, promote highly active NiFeOOH formation, and deliver durable alkaline ...

Quantum point contact due to Fermi-level pinning and doping profiles in semiconductor nanocolumns
, 2006 We show that nanoscale doping profiles inside a nanocolumn in combination with Fermi-level pinning at the surface give rise to the formation of a saddle-point in the potential profile. Consequently, the lateral confinement inside the channel varies along

Extinction bias of microlensed stars towards the LMC and the fraction of machos in the halo [PDF]
, 1999 We study the effect of reddening on microlensed stars towards the LMC. If lenses are in the LMC disk, then the source stars should be at the far side or behind the LMC disk.

AUGURAL TERRITORIES: On the Prophetic Organizing of the Mid‐range
International Journal of Urban and Regional Research, EarlyView.Abstract In this article I introduce the concept of augural territories to theorize the urbanism that emerged during pandemic lockdowns. I draw on ethnographic research in Madrid to examine how community‐based responses—including mutual aid networks, food pantries and neighbourhood associations—disrupted the spatial and temporal logics of territorial ...
