In one aspect, a method for placing carbon nanotubes on a dielectric includes: using DSA of a block copolymer to create a pattern in the placement guide layer on the dielectric which includes multiple trenches in the placement guide layer, wherein there is a first charge on sidewall and top surfaces of the trenches and a second charge on bottom surfaces of the trenches, and wherein the first charge is different from the second charge; and depositing a carbon nanotube solution onto the dielectric, wherein self-assembly of the deposited carbon nanotubes within the trenches occurs based on i) attractive forces between the first charge on the surfaces of the carbon nanotubes and the second charge on the bottom surfaces of the trenches and ii) repulsive forces between the first charge on the surfaces of the carbon nanotubes and the first charge on sidewall and top surfaces of the trenches.

A sensing system and a method utilizing same for determining and/or monitoring a presence and/or level of an analyte in a sample are provided. The sensing system is made of a nanostructure, or a plurality of nanostructures, having covalently attached thereto and a hydrogel having associated therewith a sensing moiety which selectively interacts with the analyte and being configured such that upon contacting the analyte, the nanostructure(s) exhibit a detectable change in an electrical property.

An emissive article includes an OLED having a light emission surface, a circular polarizer, and a light extraction film optically between the OLED and the circular polarizer and being optically coupled to the light emission surface. The light extraction film includes a two-dimensional structured layer of extraction elements having a first index of refraction and a pitch in a range from 400 to 800 nm and a backfill layer including a material having a second index of refraction different from the first index of refraction.

The present invention generally relates to nanoscale wires and tissue engineering. Systems and methods are provided in various embodiments for preparing cell scaffolds that can be used for growing cells or tissues, where the cell scaffolds comprise nanoscale wires. In some cases, the nanoscale wires can be connected to electronic circuits extending externally of the cell scaffold. Such cell scaffolds can be used to grow cells or tissues which can be determined and/or controlled at very high resolutions, due to the presence of the nanoscale wires, and such cell scaffolds will find use in a wide variety of novel applications, including applications in tissue engineering, prosthetics, pacemakers, implants, or the like. This approach thus allows for the creation of fundamentally new types of functionalized cells and tissues, due to the high degree of electronic control offered by the nanoscale wires and electronic circuits.

In one embodiment, a polymer includes a recurring unit containing a bivalent group expressed by a formula (1) shown below. A weight-average molecular weight of the polymer is in a range of 3000 or more to 1000000 or less. ##STR00001##
R1 is a monovalent group selected from hydrogen, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkanoyl group, a substituted or unsubstituted aryl group, and a substituted or unsubstituted heteroaryl group. X is an atom selected from oxygen, sulfur, and selenium. Y and Z are each independently a bivalent group selected from a carbonyl group, a sulfinyl group, and a sulfonyl group. A case where Y and Z are both the carbonyl groups is excluded.

The present invention, which belongs to the technical field of display technology, provides a microcapsule, a method of preparing the same, and an OLED (organic light emitting diode) display device comprising the same. The OLED display device comprises a microcapsule having a phosphorescent material as a core material, which reduces the probability of the phosphorescence self-quenching and is isolated from water and oxygen, thereby improving the display quality and extending the service life of the OLED display device. Therefore, the OLED display device can solve the problem that the phosphorescence OLED display device in the prior art has a low brightness and short service life.
