Abstract: A method for patterning layers of 2D material by inducing self-assembly on a support substrate, the method comprising the steps of depositing a layer of 2D material on the support substrate; applying a force at a region consisting of a point, a line, or an a real region of the 2D material such that the 2D material forms a folded, self-contacting structure at that region.

Abstract: Optical scanning devices and systems are disclosed. In one aspect, an optical scanning device comprises a first rotatable optical component and a second rotatable optical component. The first and second optical components are configured to rotate about a common optical axis and further configured to deflect an optical path of light transmitted or received through the optical scanning device. The device further comprises a mounting bracket positioned between the first and second optical components and comprises first and second motor assemblies configured to rotate the corresponding first and second optical components about the optical axis independently of each other. An inner portion of each of the first and second optical components is mounted to an outer portion of the corresponding first and second motor assemblies such that the optical axis is configured to extend through the center of the first and second optical components and tubes.

Abstract: A non-linear chromophore is obtained by reacting a picolinium halide having a desired functional group (preferably —OH) with a lithium TCNQ adduct. If desired, the chromophore can be graft polymerized onto a polymer which has complementary functional groups (preferably carboxyl groups). Optionally the polymer can then be cross-linked. Such polymers are useable in electro-optical devices.
