Communication: Growing room temperature ice with graphene

Water becomes ordered in the form of hexagonal ice at room temperature under controlled humidity conditions upon confinement in the nanometer range between protective graphene sheets and crystalline (111) surfaces with hexagonal symmetry of the alkali eart ...

Signs of critical transition in the Everglades wetlands in response to climate and anthropogenic changes

Andrea Rinaldo

The increasing pressure of climatic change and anthropogenic activities is predicted to have major effects on ecosystems around the world. With their fragility and sensitivity to hydrologic shifts and land-use changes, wetlands are among the most vulnerabl ...

Robust Localization from Incomplete Local Information

Amin Karbasi

We consider the problem of localizing wireless devices in an ad-hoc network embedded in a

d

-dimensional Euclidean space. Obtaining a good estimation of where wireless devices are located is crucial in wireless network applications including environment m ...

Signatures of quantum criticality in the thermopower of Ba(Fe1-xCox)(2)As-2

László Forró, Richard Gaal, Stevan Arsenijevic

We demonstrate that the thermopower (S) can be used to probe the spin fluctuations (SFs) in proximity to the quantum critical point (QCP) in Fe-based superconductors. The sensitivity of S to the entropy of charge carriers allows us to observe an increase o ...

Spatially resolved magnetization in the Bose-Einstein condensed state of BaCuSi2O6: Evidence for imperfect frustration

Frédéric Mila, Nicolas Laflorencie

In order to understand the nature of the two-dimensional Bose-Einstein condensed (BEC) phase in BaCuSi2O6, we performed detailed Cu-63 and Si-29 NMR above the critical magnetic field, H-c1 = 23.4 T. The two different alternating layers present in the syste ...

Interface debonding driven by fluid injection in a cased and cemented wellbore: Modeling and experiments

Brice Tanguy Alphonse Lecampion

The integrity of the wellbore completion under injection conditions is vital for the effective, long term storage of carbon dioxide. Here we experimentally demonstrate and mathematically model fluid-driven debonding of the wellbore annulus in order to prov ...

Flexible and Robust Multilayer Micro-Vibrational Harvesters for High Acceleration Environments

Nico de Rooij, Danick Briand, Andres Felipe Vasquez Quintero, Pattanaphong Janphuang, Robert Andrew Lockhart

This paper presents the fabrication and characterization of multilayer PVDF resonant micro-vibrational energy harvesters designed to withstand environments in which high levels of acceleration are present. The multilayer cantilevers are fabricated by combi ...

Pr4Fe2As2Te1-xO4: A layered FeAs-based superconductor

László Forró, Richard Gaal, Janusz Andrzej Karpinski, Andrea Pisoni, Sergiy Katrych

We report crystal growth at high pressure, structure determination, and magnetic and transport studies of an oxypnictide superconductor Pr4Fe2As2Te1-xO4. Its structure resembles the known 1111 phase except for the considerably larger c lattice constant and ...

Field-Induced Quantum Soliton Lattice in a Frustrated Two-Leg Spin-1/2 Ladder

Henrik Moodysson Rønnow, Christian Rüegg, Siyuan Wang, Joël Mesot, Kazimierz Conder

Based on high-field 31P nuclear magnetic resonance experiments and accompanying numerical calculations, it is argued that in the frustrated S=1/2 ladder compound BiCu2PO6 a field-induced soliton lattice develops above a critical field of μ0Hc1=20.96(7) T. ...

A 3D lattice Boltzmann effective media study: understanding the role of C-S-H and water saturation on the permeability of cement paste

Karen Scrivener, Mohamad Zalzale

A 3D lattice Boltzmann model is developed and used to calculate the water and gas permeabilities of model cement pastes at different degrees of water saturation. In addition to permeable micron-sized capillary pores and impermeable solid inclusions, the la ...
