 This invention provides a novel and straightforward antimicrobial concentrate that takes advantage of the highly effective antimicrobial property of the acidified water-in-oil emulsions. This concentrate can be easily introduced to the processing equipment during oil cleaning procedures.                                           

This invention demonstrates the use of a commoner additive, cyclic allyl sufide (CAS), to introduce recyclability into vinyl-based polymers through radically initiated scission and extension.

 The invention takes advantage of alkyne-azole chemistry to produce impressive non-toxic and safe flame-retardant polymers and additives that can be integrated into industrial processes. 

This invention demonstrates solid or semi-solid microparticles that undergo crosslinking and polymerization upon contacting a substrate to form a coating. The microparticles are maintained in an un-reacted state until delivered using cold spray processes where they are propelled using a gas stream at a pre-determined temperature and velocity. The process does not require volatile organic solvents or aqueous vehicles, nor plural component spray or two component formulations with limited shelf life but still deliver uniform coating.

This invention provides novel, deoxybenzoin-based anti-flammable polymers and cured epoxy resins for a variety of end-use applications.

This invention provides new chemical compositions and methods for the preparation of adhesive materials with low flammability. The low flammability is due to newly invented organic/polymeric components used in the adhesive formulation, rather than through the addition of a conventional anti-flammable additives such as halogenated organic molecules or phosphorous-containing structures.

This invention provides a new class of zwitterionic polymers that exhibit hydrophobic properties and are soluble in polar organic solvents, allowing for their use as novel polymeric surfactants, and as functional materials in other applications.

Zeolites have found wide application in catalysis and separation processes due to their tunable pore structure and active sites, and they show remarkable stability in commercial use. Recently, ultra-thin two-dimensional (2D) zeolite nanosheets have been synthesized from zeolite precursors. These ultra-thin nanosheets show promise for high throughput separations and catalytic reactions involving bulky molecules. A commercially feasible synthesis method, however, has yet to be developed. State-of-the-art methods require high energy input and multiple processing steps, and give low yield and small nanosheet size.

 

Professors Winter and Fan have developed a simpler, lower energy method to synthesize ultra-thin 2D zeolite nanosheets from precursor zeolite materials, such as MCM-22 and ml-MFI. In the method, zeolite precusors can be subjected to either a short sonication or chaotic flow treatment in the presence of commercially available telechelic polymers, resulting in exfoliated zeolite nanosheets. While demonstrated in batch, this process can potentially be scaled and made continuous.
