Soft nanofluidics governing minority ion exclusion in charged hydrogels

Songmei Wu, Thomas Michael Braschler, Fabien Patrick Wildhaber

We investigate ionic partition of negatively charged molecular probes into also negatively charged, covalently crosslinked alginate hydrogels. The aim is to delimit the domain of validity of the major nanoelectrostatic models, and in particular to assess t ...

Design of Single-Molecule Magnets: Insufficiency of the Anisotropy Barrier as the Sole Criterion

Jan Gui-Hyon Dreiser

Determination of the electronic energy spectrum of a trigonalsymtnetry mononuclear Yb3+ single-molecule magnet (SMM) by highresolution absorption and luniinescente spectroscopies reveals that the first excited electronic doublet is placed nearly 500 cm(-1) ...

Air concentration distribution in deflector-jets

Michael Pfister, Sebastian Schwindt

As an alternative to ski jumps, deflectors can be implemented on spillways to generate free jets. They guide, up to a certain limit, the jet to an achieved location onto the plunge pool surface, and furthermore enhance the process of jet disintegration. Th ...

Robust production of purified H-2 in a stable, self-regulating, and continuously operating solar fuel generator

Sophia Haussener, Miguel Antonio Modestino

The development of practical solar-driven electrochemical fuel generators requires the integration of light absorbing and electrochemical components into an architecture that must also provide easy separation of the product fuels. Unfortunately, many of th ...

Chemisorbed Molecules under Potential Bias: Detailed Insights from First-Principles Vibrational Spectroscopies

Nicola Marzari, Nicéphore Arthur François Bonnet

The electrochemical factors that control the interaction of a chemisorbed molecule under potential bias are identified by considering the vibrational response of carbon monoxide on a platinum electrode from first principles. Using three complementary appro ...

Memristor-Based Devices for Sensing

Giovanni De Micheli, Sandro Carrara, Francesca Puppo

In this paper we propose CMOS-compatible Memristive-Biosensors as label-free, highly sensitive sensors for in-air detection of Vascular Endothelial Growth Factor (VEGF) molecules. The memristive behavior of the fabricated devices is strongly affec ...

Empirical Monod-Beuneu relation of spin relaxation revisited for elemental metals

László Forró

Monod andBeuneu [P. Monod and F. Beuneu, Phys. Rev. B 19, 911 (1979)] established the validity of the ElliottYafet theory for elemental metals through correlating the experimental electron spin resonance linewidth with the so-called spin-orbit admixture co ...

Biexcitonic molecules survive excitons at the Mott transition

Nicolas Grandjean, Jean-François Carlin, Benoît Marie Joseph Deveaud, Eric Feltin, Raphaël Butté, Jean-Daniel Ganière, Gwénolé Jean Jacopin, Jacques Levrat, Georg Rossbach, Mehran Shahmohammadi

When the carrier density is increased in a semiconductor, according to the predictions of Sir Nevil Mott, a transition should occur from an insulating state consisting of a gas of excitons to a conductive electron-hole plasma. This crossover, usually refer ...
