Specific Ion Effects at the Interface of Nanometer-Sized Droplets in Water: Structure and Stability

Sylvie Roke, Evangelia Zdrali, Halil Ibrahim Okur

The interaction of ions with interfaces influences numerous processes in chemistry, physics, and biology, while different ion species behave differently at hydrophobic or hydrophilic interfaces. Despite its importance, ion specificity and its relation to s ...

Unravelling the precipitation pathway of biorelevant minerals: from fundamental studies to biomedical applications

Agnese Carino

The formation pathway of biominerals archetypes, namely calcium carbonate (CaC) and calcium phosphates (CaPs), was investigated using a multidisciplinary approach. The time-resolved analytical data were collected using a controlled-composition method and i ...

Assessing the Effect of Calcite Impurities in Clay on Optimal Dehydroxylation Parameters for Enhanced Reactivity

Karen Scrivener, Franco Alberto Zunino Sommariva

This study focused on understanding the influence of different amounts of calcite impurities (0 to 10% by mass) on the optimal parameters for clay dehydroxylation and the reactivity of the final calcined clay. A surface response experimental design was use ...

The Jones–Ray Effect Is Not Caused by Surface-Active Impurities

Sylvie Roke, Halil Ibrahim Okur, Eric Tyrode

Pure aqueous electrolyte solutions display a minimum in surface tension at concentrations of 2 ± 1 mM. This effect has been a source of controversy since it was first reported by Jones and Ray in the 1930s. The Jones–Ray effect has frequently been dismisse ...

Optical imaging of surface chemistry and dynamics in confinement

Sylvie Roke, Carlos Alberto Macias Romero, Halil Ibrahim Okur, Igor Nahálka

We imaged the interfacial structure and dynamics of water in a microscopically confined geometry in three dimensions and on millisecond time scales with a 3D structurally illuminated wide-field second harmonic microscope. Image contrast reports on the orie ...

Clean, cleaved surfaces of the photovoltaic perovskite

László Forró, Jeremy Luterbacher, Bálint Náfrádi, Henrik Moodysson Rønnow, Luka Ciric, Endre Horvath, Stefan Peter Muff, Jan Hugo Dil, Benjamin Pierre Le Monnier, Andrew Patton Weber, Márton Kollár

The surface of a material is not only a window into its bulk physical properties, but also hosts unique phenomena important for understanding the properties of a solid as a whole. Surface sensitive techniques, like ARPES (Angle-resolved photoemission spect ...

Extracting the interfacial free energy and anisotropy from a smooth fluctuating dividing surface

Michele Ceriotti, Edoardo Baldi, Gareth Aneurin Tribello

Interfaces between different materials and phases play a crucial role in many physical and chemical phenomena. When performing simulations of matter at the atomic scale, however, it is often not trivial to characterize these interfaces, particularly when t ...

Energy management in manufacturing: From literature review to a conceptual framework

Dimitrios Kyritsis, Gökan May

The literature on energy management in manufacturing is rapidly growing. Since the literature is also quite fragmented, we believe that the time has come to delve into current knowledge in the research field to provide directions for policy makers and guid ...

The Molecular Mechanism of Nanodroplet Stability

Yixing Chen, Sylvie Roke, Evangelia Zdrali, David Mark Wilkins, Halil Ibrahim Okur

Mixtures of nano- and microscopic oil droplets in water have recently been rediscovered as miniature reaction vessels in microfluidic environments and are important constituents of many environmental systems, food, personal care, and medical products. The ...

Lipid membrane characterization with second harmonic scattering : surface potentials, ionization, membrane asymmetry and hydration

Cornelis Ulrich Lütgebaucks

Membranes, composed of a variety of lipids and other biomolecules, mediate signaling processes between cells and their aqueous environment. To fulfill this function, membranes can vary their composition leaflet-specific and thus alter their surface propert ...
