Single Molecule Studies on Dynamics in Liquid Crystals

Single molecule (SM) methods are able to resolve structure related dynamics of guest molecules in liquid crystals (LC). Highly diluted small dye molecules on the one hand explore structure formation and LC dynamics, on the other hand they report about a distortion caused by the guest molecules. The anisotropic structure of LC materials is used to retrieve specific conformation related properties of larger guest molecules like conjugated polymers. This in particular sheds light on organization mechanisms within biological cells, where large molecules are found in nematic LC surroundings. This review gives a short overview related to the application of highly sensitive SM detection schemes in LC.

Crystalline Tectonics: An Architect's Guide to 3D-Printing Sugar or Anything Else

Architecture and the culinary arts appear as polar opposites: one generally designed to last, the other inherently ephemeral. But for Kyle von Hasseln , a postgraduate architecture research project became the starting point for the two to come together, when he and his partner Liz von Hasseln tried out their second-hand 3D printer with some novel materials. Sugar, chocolate, milk powder, dehydrated powdered fruit: the Los Angeles design firm they cofounded – now known as 3D Systems Culinary Lab – has experimented with them all. Presenting their work, Kyle ponders how it recalls elaborate historical desserts, but with structurally poetic and sometimes challenging twists.
