Non–Close-Packed Nanoparticle Arrays: Porous Materials with Novel Crystal Structures Assembled from Nanoparticles

Self-assembly of inorganic nanoparticles has been used to prepare hundreds of different colloidal crystals, but almost invariably with the restriction that the particles must be densely packed. Here, we show that non–close-packed nanoparticle... (Read more)

Non-Invasive, Label-Free Detection and Imaging of Quorum Sensing

The development of non-invasive methods for monitoring chemical communication in bacterial populations is important to provide fundamental insights into these processes as well as the necessary knowledge to manipulate these systems for applications... (Read more)

Proteins as Soft Matter: Interactions, Phase Behaviour and Health Research

Protein-protein interactions govern phase behaviour and stability in protein solutions. For this reason, they are relevant to the understanding of physiological and pathological processes, and crucial for the formulation and storage of biopharmaceuticals... (Read more)

Finite element simulations show that a combination of convection and thermodiffusion enriches formamide in the pore (contour plot). The graph illustrates the accumulation normalized to the reservoir concentration ω_0 over time for different ω_0. The accumulation saturates around a formamide concentration of 85 wt%. The time necessary to reach the plateau τ_plateau depends on the reservoir concentration ω_0 (inset). Copyright: Forschungszentrum Jülich

Origin of Life: Accumulation of Formamide in Hydrothermal Pores to Form Prebiotic Nucleobases

One of the central questions of humankind is: which chemical and physical conditions are necessary to make life possible? In this “origin-of-life” context, formamide plays an important role, because it has been demonstrated... (Read more)
