Abstract: Methods for producing surface functionalized silicon nanoparticles like Si-QDs using a continuous gas-phase synthesis by direct pyrolysis of aerosolized higher order liquid silanes like cyclohexasilane (Si6H12) or cyclopentasilane (Si5H10) to produce nanoscale particles are provided. The methods permit control over the particle characteristics i.e., crystallinity, core-shell, size and surface chemistry of Si nanostructures and allow the tuning of the band gap (absorption) and manipulation of photo responsive properties. A wide variety of modifications can be performed using the hydrogen (H) or hydroxyl (OH) groups attached to silicon atoms on the particle surface. The coupling of different molecules or complexes directly to the silicon atoms of the particles allows the engineering of desirable optical, chemical or biological activity to the particles or can act as linkers to agglomerate particles or form porous films.

Abstract: Methods for forming silicon thin films and structures with incorporated metals, non-metals, and combinations thereof, liquid precursor compositions useful in such methods, and silicon thin films and structures with embedded heteroatom(s) are described. The compositions are generally liquid at ambient temperature and are comprised of liquid silane(s) and have metal and/or non-metal additives. Metal and non-metal sources include organometallic and organic compounds, respectively. The compositions may also contain a solvent. The compositions may be processed by printing, coating, or spraying onto a substrate and subjected to UV, thermal, IR, and/or laser treatment to form silicon films or structures with embedded heteroatom(s).

Abstract: Applicants have produced a chromophore and a polymer that are highly sensitive to the presence of various agents, including organophosphates, pesticides, neurotoxins, metal ions, some explosives, and biological toxins. The detection is accomplished by detecting a change in the fluorescence characteristics of the chromophore or polymer when in the presence of the agent to be detected. The chromophore and polymer may be incorporated into sensors of various types, and they are adaptable for potential field use in areas where detection of these types of agents is desired.

Abstract: Anti-fouling materials may include one or more of a number of suitable copolymers (e.g., block copolymers, graft copolymers, etc.) which provide biocidal and/or fouling release characteristics. The copolymers may include a polysiloxane backbone with one or more polymers grafted onto the polysiloxane backbone.
