Reversible Local and Global Switching in Multicomponent Supramolecular Networks: Controlled Guest Release and Capture at the Solution/Solid Interface

Magalí Alejandra Lingenfelder, Fernando Pablo Cometto

Dynamically switchable supramolecular systems offer exciting possibilities in building smart surfaces, the structure and thus the function of which can be controlled by using external stimuli. Here we demonstrate an elegant approach where the guest binding ...

A New Analytical Model for the Prediction of Stream Temperature in Ungauged Basins

Michael Lehning, Wolf Hendrik Huwald, Bettina Schaefli, Aurélien Gallice

Stream temperature is a hydrological factor which affects the habitat suitability of many aquatic species, and is therefore of great concern in the actual context of climate change. Its prediction in ungauged basins is usually based on statistical approach ...

Chemical Equilibria in Formic Acid/Amine-CO2 Cycles under Isochoric Conditions using a Ruthenium(II) 1,2-Bis(diphenylphosphino)ethane Catalyst

Gabor Laurenczy, Katerina Stefania Sordakis, Matthias Beller

The equilibrium position in formic acid/amine–CO2 systems has been examined as a function of pressure and tem- perature under isochoric conditions. The homogeneous ruthe- nium(II)-1,2-bis(diphenylphosphino)ethane catalyst was active in both reactions, that ...

Atmospheric amines and ammonia measured with a chemical ionization mass spectrometer (CIMS)

Athanasios Nenes, Satoshi Takahama, Giulia Ruggeri, Hairun Guo

We report measurements of ambient amines and ammonia with a fast response chemical ionization mass spectrometer (CIMS) in a southeastern US forest and a moderately polluted midwestern site during the summer. At the forest site, mostly C3-amines (from pptv ...

Time reversal symmetry in time-dependent correlation functions for systems in a constant magnetic field

Sara Bonella

A generalised time reversal symmetry for systems subject to a constant magnetic field is introduced, based on the analogy between the evolution equations of these systems and those of a system subject to shear. This generalisation makes it possible to deri ...

Reversal Mechanism of an Individual Ni Nanotube Simultaneously Studied by Torque and SQUID Magnetometry

Dirk Grundler, Eleonora Russo

Using an optimally coupled nanometer-scale SQUID, we measure the magnetic flux originating from an individual ferromagnetic Ni nanotube attached to a Si cantilever. At the same time, we detect the nanotube's volume magnetization using torque magnetometry. ...

Fast Crystallization of the Phase Change Compound GeTe by Large-Scale Molecular Dynamics Simulations

Giacomo Francesco Leonardo Miceli, Federico Giberti

Phase change materials are of great interest as active layers in rewritable optical disks and novel electronic nonvolatile memories. These applications rest on a fast and reversible transformation between the amorphous and crystalline phases upon heating, ...

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 ( ...

SNOWPACK: where do we stand today?

Michael Lehning, Nander Wever, Mathias Thierry Pierre Bavay, Charles Fierz

The Swiss snow-cover model SNOWPACK is presently used in many applications from snow sports and engineering to climate change assessment but also for avalanche warning. The core routines are packed in a library that also serves as the basic module for the ...
