When atomic-scale resolution is not enough: Spatial effects in in situ model catalyst studies [PDF]
We investigate transport effects in in situ studies of defined model catalysts using a multi-scale modeling approach integrating first-principles kinetic Monte Carlo simulations into a fluid dynamical treatment.

Soybean-Oil-Based CO2-Switchable Surfactants with Multiple Heads
Oligomeric surfactants display the novel properties of low surface activity, low critical micellar concentration and enhanced viscosity, but no CO2 switchable oligomeric surfactants have been developed so far. The introduction of CO2 can convert tertiary

Modulating the catalytic activity of enzyme-like nanoparticles through their surface functionalization [PDF]
The inclusion of transition metal catalysts into nanoparticle scaffolds permits the creation of catalytic nanosystems (nanozymes) able to imitate the behaviour of natural enzymes.

Activity of surface active substances determined from their surface excess [PDF]
Commonly, the surface excess is determined from surface tension measurements via the Gibbs equation. This equation relates the activity (chemical potential), the surface excess, and the surface tension. When knowing two out of the three quantities, the third one can be calculated.

Gold Nanoparticles on Yttrium Modified Titania: Support Properties and Catalytic Activity [PDF]
A series of titanium oxide catalysts modified with yttrium has been prepared by sol¿gel method and their structural properties have been studied. The incorporation of yttrium in the titania lattice favors the formation of oxygen vacancies while at low Y ...

Palmitoylcarnitine, a surface‐active metabolite [PDF]
Palmitoylcarnitine is a well‐known intermediate in mitochondrial fatty acid oxidation. Less known are its properties as a surfactant, with a capacity to solubilize biological membranes similar to that of many synthetic detergents used in the biochemical laboratory.

Original Multivalent Gold (III) and Dual Gold(III)-Copper(II) Conjugated Phosphorus Dendrimers as Potent Antitumoral and Antimicrobial Agents [PDF]
Original metallophosphorus dendrimers (generation 3, 48 terminal groups) have been prepared via the complexation of phosphorus dendrimers bearing imino-pyridino end groups with Au(III) or with both Au(III) and Cu(II).

Local manifestations of cometary activity [PDF]
Comets are made of volatile and refractory material and naturally experience various degrees of sublimation as they orbit around the Sun. This gas release, accompanied by dust, represents what is traditionally described as activity.
