Charge change: How electric forces vary in colloids

When calculating electrokinetic force, the convention has been to assume that there is no relative velocity of the fluid compared to the surface, which holds true for hydrophilic surfaces. However, this needs to be reconsidered ...

Extremely tiny, hugely versatile nanoglobules

Ludwig Maximilian University chemists have demonstrated a simple way to load nanoglobules with light-absorbing organic molecules. The method could serve as the basis for the formulation of innovative sunscreens.

Technique simplifies the creation of high-tech crystals

Highly purified crystals that split light with uncanny precision are key parts of high-powered lenses, specialized optics and, potentially, computers that manipulate light instead of electricity. But producing these crystals ...

Sieve holds nanoparticles and acts as solar absorber

(Phys.org)—A membrane consisting of polymer fibres and proteins makes a novel filter for tiny, nano-scaled particles in aqueous solutions. The result of such a research, which was done by Professor Mady Elbahri and his ...

Making complex fluids look simple

An international research team has successfully developed a widely applicable method for discovering the physical foundations of complex fluids for the first time. Researchers at the University of Vienna and University of ...
