TL;DR: It is demonstrated that oligo(phenylene ethynylene), a conjugated organic molecule, acts like a molecular wire under symmetric contact conditions, but exhibits characteristics of a molecular diode when the connections are asymmetric.

TL;DR: Junction conductance as a function of molecular structure is consistent with I-V characteristics calculated from extended Hückel theory coupled with a Green's function approach, and can be understood on the basis of bond-length alternation.

TL;DR: Optical and x-ray scattering studies of a chiral, organosiloxane smectic-A liquid crystal indicate a large field induced optical tilt of up to 31 degrees accompanied by a very small contraction of thesmectic layers, suggesting that the molecules have a nonzero tilt even with no applied field.

TL;DR: An experimentally simple crossed‐wire tunnel junction is used to interrogate how factors such as metal‐molecule coupling, molecular structure, and the choice of metal electrode influence the current‐voltage characteristics of a molecular junction.

TL;DR: A method for fabricating capillary-based immunosensors in a coupon milled from an inexpensive, commodity plastic (PMMA, plexiglass) is demonstrated and the key feature of the technique is the use of sol-gel technology to deposit a glass-like film on surfaces of the plastic capillary channels to facilitate antibody immobilization.
