TL;DR: A simple yet effi cient approach for droplet transport is demonstrated, in which the droplet is moving on a superhydrophobic surface, using gravity or electrostatic forces as the driving force for droplets transportation and using tracks with vertical walls as gravitational potential barriers to design trajectories.

TL;DR: In this article, a SEM examination of the fracture surface of a slowly-dried cellulose film showed a surprisingly regular fan-like pattern which was shown to be characteristic of cross-sections of the left-handed helicoidal arrangement of nanocrystals, where the helicoidal axis was almost perpendicular to the film surfaces.

TL;DR: The percolation threshold for conductivity is observed at astonishingly low weight fractions of the conjugated conducting polyaniline indicating the formation of a unique morphology.

TL;DR: This work shows that vulnerability can be solved by superamphiphobic (i.e., both superhydrophobic and superoleophobic) surfactant-coated aerogel surfaces, and predicts that the concept can open routes for robust self-cleaning coating technologies.

TL;DR: In this paper, the mesomorphic behavior of poly(2-vinylpyridine) (P2VP) and poly(4vinyl pyridine (P4VP) with p-dodecylbenzenesulfonic acid (DBSA), characterized by FT-IR, was investigated in the bulk and in xylene, i.e., a good solvent for the alkyl side chains.
