摘要:
A chemical detector for rapid, simultaneous detection of multiple chemicals including chemical warfare agents, toxic industrial chemicals, and explosives having one or more gas chromatography columns each with a chemosorbent or a chemo-reactive stationary phase and an infrared-transparent base, a bright infrared light source, a mechanism to direct the light source to any point along any of the columns, and an infrared sensor. Another disclosed detector has one or more gas chromatography columns each on the surface of a substrate having at least one infrared-transparent waveguide pattern, a bright infrared light source, and at least one ring resonator for each column, where each ring resonator is coated with a chemosorbent or a chemo-reactive stationary phase, and where each ring resonator spectroscopically probes the stationary phase. Also disclosed are the related methods for chemical detection.

Disclosed herein is a composition having a plurality of particles of a filler material and crosslinking units having the formula —(SiR—CH2—CH2—CH2)—. The silicon atom in the crosslinking unit is directly or indirectly bound to the filler material. Each R is alkyl, alkenyl, phenyl, methyl, ethyl, allyl, halogen, chloro, or bromo. Also disclosed herein is a filler material having the silicon atom of a silacyclobutane group is directly or indirectly bound thereto. Also disclosed herein is a method of crosslinking silacyclobutane groups bound to a plurality of particles of a filler material. The silicon atom of the silacyclobutane group is directly or indirectly bound to the filler material. Also disclosed herein is a composition including a plurality of fibers of a polymer having reactive oxygen atoms and siloxane groups. Coordination bonds are formed between the oxygen atoms and the silicon atoms of the siloxane groups of separate fibers.

摘要:
This invention pertains to transfer of a solid target material onto a substrate by vaporizing the material by irradiating it with intense light of a resonant vibrational mode of the material and depositing the vaporized material on a substrate in a solid form.
