    摘要： 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.

    摘要： A chemical sensor and a system and method for sensing a chemical species. The chemical sensor includes a plurality of nanofibers whose electrical impedance varies upon exposure to the chemical species, a substrate supporting and electrically isolating the fibers, and a set of electrodes connected to the plurality of fibers at spatially separated points to permit the electrical impedance of the plurality of fibers to be measured. The system includes the chemical sensor, an impedance measuring device coupled to the electrodes and configured to determine an electrical impedance of the plurality of fibers, and an analyzer configured to identify the chemical species based on a change in the electrical impedance. The method measures at least one change in an electrical impedance between spatially separated electrodes, and identifies the chemical species based on the measured change in the electrical impedance.

    摘要： A braille printing device is disclosed. The device comprises a paper picking-up mechanism, a paper feeding mechanism, a printing mechanism, a curing light source (8) and a paper discharging mechanism. The paper picking-up mechanism, the printing mechanism, the curing light source and the paper discharging mechanism are arranged above a base (6) in turn. The paper feeding mechanism is installed in an X-direction guide on the base (6) and moves to and fro along the X-direction guide under the paper picking-up mechanism, the printing mechanism, the curing light source (8) and the paper discharging mechanism. The printing mechanism is fixed to two posts (16) at two sides of the middle of the base (6). The curing light source (8) and a glue jet valve (10) of the printing mechanism are disposed at two sides of the posts (16) respectively. Electromagnetic clamps (7) of the paper discharging mechanism are mounted at the end of the base (6). The device can simultaneously perform printing and curing operations.
