    摘要： A switching device includes at least one bottom electrode and at least one top electrode. The top electrode crosses the bottom electrode at a non-zero angle, thereby forming a junction. A metal oxide layer is established on at least one of the bottom electrode or the top electrode. A molecular layer including a monolayer of organic molecules and a source of water molecules is established in the junction. Upon introduction of a forward bias, the molecular layer facilitates a redox reaction between the electrodes, thereby reducing a tunneling gap between the electrodes.

    摘要： An apparatus for sensing at least one property of a fluid is described. A first photonic crystal structure and a second photonic crystal structure are defined in a dielectric slab. The first and second photonic crystal structures comprise differently patterned arrays of channels extending through the dielectric slab. The apparatus further comprises a fluid introduction device configured to introduce a common volume of the fluid into the channels of the first and second photonic crystal structures. The at least one property of the fluid can be sensed by measuring the propagation of radiation through the first and second photonic crystal structures.

    摘要： Systems and methods for synthesizing molecules on a substrate surface are disclosed. In one aspect, a molecule synthesizing system includes a crossbar array with a planar arrangement of crossbar junctions. Each crossbar junction is independently switchable between a high-resistance state and a low-resistance state. The system also includes a slab with a first surface and a second surface parallel to the first surface. The second surface is disposed on the crossbar array. A current applied to a crossbar junction in a high-resistance state creates an adjacent heated site on the first surface for attaching thermally reactive molecules for molecular synthesis.
