A white organic light emitting diode (OLED) display device and a method of manufacturing the same are provided. By making an organic fluorescent color conversion film including a first conversion film and a second conversion film respectively disposed on a green color resist and a red color resist, the first conversion film converts cyan light into green light, and the second conversion film converts yellow orange light into red light. This can improve color gamut and color conversion rate of the white OLED display device and improve density of the organic color conversion film and stability of a device.

The invention provides compositions and methods for cytosolic delivery of peptides and antigens as well as concomitant delivery of antigens and agonists via poly-norbornene-based protein transduction domain mimics.

A single-walled carbon nanotube composition includes single-walled carbon nanotubes substantially enriched in semiconducting single-walled carbon nanotubes in association with a polymer having one or more oligoether side groups. The oligoether side groups render the composition dispersable in polar organic solvents, for example alkyl carbitols, permitting formulation of ink compositions containing single-walled carbon nanotubes substantially enriched in semiconducting single-walled carbon nanotubes. Such ink compositions may be readily printed using common printing methods, such as inkjet, flexography and gravure printing.

Provided is a maleimide resin with superior solution stability. Also provided is a cured product with a superior dielectric characteristic that is obtained by curing a curable resin composition in which said maleimide resin is used. The maleimide resin expressed in formula (1). (In formula (1), each of the plurality of Rs independently represents a C1-5 alkyl group, n is the number of repetitions, and the average value thereof is 1<n<5.)
