    Abstract: A device for stimulable light emission that includes a fiber mat of nanofibers having an average fiber diameter in a range between 100 and 2000 nm, and includes plural stimulable particles disposed in association with the nanofibers. The stimulable particles produce secondary light emission upon receiving primary light at a wavelength λ. The average fiber diameter is comparable in size to the wavelength λ in order to provide scattering sites within the fiber mat for the primary light. Various methods for making suitable luminescent nanofiber mats include: electrospinning a polymer solution including or not including the stimulable particles and forming from the electrospun solution nanofibers having an average fiber diameter between 100 and 2000 nm. Methods, which electrospin without the stimulable particles, introduce the stimulable particles during electrospinning or after electrospinning to the fibers and therefore to the resultant fiber mat.

    Abstract: There is provided a dry-wet spinning device for an acrylic precursor fiber bundle for manufacturing carbon fibers, the device enabling stable spinning by making the coagulability of spun yarn (2) uniform by suppressing the vibration of the coagulating liquid surface to make the spun yarn (2) spun downward from a spinneret (1) without the liquid surface being in contact with the spinning surface of the spinneret less susceptible to an accompanying flow reflected by the bottom surface of a spinning bath. To this end, in the present invention, a horizontal flow straightening plate (8) produced from a porous plate or a plate material extending in the direction approximately perpendicular to the direction in which the spun yarn (2) is spun is disposed in a coagulation bath so as to surround the circumference of the yarn spun downward from the spinneret (1). Further, a vertical flow straightening plate (9) extending vertically across part or all of the outer periphery of the horizontal flow straightening plate (8) can be provided.

    Abstract: Solutions formed by combining poly(α(1→3) glucan) with CS2 in aqueous alkali metal hydroxide solution have been shown to produce the xanthated form of the poly(+(1→3) glucan). The solutions so formed have been shown to be useful for solution spinning into fiber of poly(α(1→3) glucan) when the spun fiber is coagulated in an acidic coagulation bath. The fibers so produced exhibit desirable physical properties. The poly(α(1→3) glucan) employed was synthesized by fermentation.
