Universal Casimir attraction between filaments at the cell scale

The electromagnetic Casimir interaction between dielectric objects immersed in salted water includes a universal contribution that is not screened by the solvent and therefore long-ranged. Here, we study the geometry of two parallel dielectric cylinders. W ...

Second harmonic scattering of nanoparticles: A journey into the electrical double layer

Bingxin Chu

In aqueous solutions, a charged surface causes the redistribution of nearby ions. The ion layers formed are known as the electrical double layer (EDL), and are widespread in many systems involving electrochemistry, colloidal science, biomedicine, and energ ...

Quantitative electronic structure and work-function changes of liquid water induced by solute

Bruno Credidio

Recent advancement in quantitative liquid-jet photoelectron spectroscopy enables the accurate determination of the absolute-scale electronic energetics of liquids and species in solution. The major objective of the present work is the determination of the ...

Aqueous electrolytes for high-voltage batteries and supercapacitors

David Reber

Lithium-ion batteries are widely implemented as energy storage devices due to their high energy density and low cost. They enabled modern portable electronics and electric ve-hicles, and are key to manage the integration of intermittent renewable electrici ...

Polycation Interactions with Zwitterionic Phospholipid Monolayers on Oil Nanodroplets Suspensions in Water (D2O) Probed by Sum Frequency Scattering

Sylvie Roke, Nikolay Smolentsev

By combining dynamic light scattering (DLS) measurements and infrared (IR) spectroscopy with the interface- and bond-specificity of vibrational sum frequency generation scattering (SFS) spectroscopy, we probe several structural aspects of how zwitterionic ...

Catalytic supercritical water gasification: Interaction of sulfur with ZnO and the ruthenium catalyst

Christian Ludwig, Frédéric Vogel, Gaël Peng

Continuous catalytic supercritical water gasification (CSCWG; 400 degrees C, 28 MPa) of microalgal biomass (Chlorella vulgaris) was carried out at the microalgae production site of ZHAW in Wadenswil (Switzerland) non-stop over a period of 100 h. Characteri ...

Guanidinium can both Cause and Prevent the Hydrophobic Collapse of Biomacromolecules

Halil Ibrahim Okur

A combination of Fourier transform infrared and phase transition measurements as well as molecular computer simulations, and thermodynamic modeling were performed to probe the mechanisms by which guanidinium (Gnd(+)) salts influence the stability of the co ...

Influence of Fluorinated Surfactant Composition on the Stability of Emulsion Drops

Esther Amstad, Gianluca Nicolas Etienne, Michael David Kessler

Aqueous drops of a well-defined size are often used as small containers for conducting chemical and biochemical reactions, cell assays and as templates to produce microparticles. To prevent their coalescence, they must be stabilized, for example, using sur ...

Quantum versus classical protons in pure and salty ice under pressure

Richard Gaal, Livia Eleonora Bove Kado

It is generally accepted that nuclear quantum effects (NQEs) trigger the transition to the nonmolecular form of ice under increasing pressure. This picture is challenged in salty ice, where Raman scattering measurements up to 130 GPa of molecular ice VII c ...

Prolonged river water pollution due to variable-density flow and solute transport in the riverbed

David Andrew Barry

A laboratory experiment and numerical modeling were used to examine effects of density gradients on hyporheic flow and solute transport under the condition of a solute pulse input to a river with regular bed forms. Relatively low-density gradients due to a ...
