Surface chemical modification of nanocrystals

Patent Helms, Brett Anthony; Milliron, Delia Jane; Rosen, Evelyn Louise; ...

Nanocrystals comprising organic ligands at surfaces of the plurality of nanocrystals are provided. The organic ligands are removed from the surfaces of the nanocrystals using a solution comprising a trialkyloxonium salt in a polar aprotic solvent. The removal of the organic ligands causes the nanocrystals to become naked nanocrystals with cationic surfaces.

Method for chemical surface modification of fumed silica particles

Patent Grabbe, Alexis [Albuquerque, NM]; Michalske, Terry Arthur [Cedar Crest, NM]; Smith, William Larry [Albuquerque, NM]

Dehydroxylated, silica-containing, glass surfaces are known to be at least partially terminated by strained siloxane rings. According to the invention, a surface of this kind is exposed to a selected silane compound or mixture of silane compounds under reaction-promoting conditions. The ensuing reaction results in opening of the strained siloxane rings, and termination of surface atoms by chemical species, such as organic or organosilicon species, having desirable properties. These species can be chosen to provide qualities such as hydrophobicity, or improved coupling to a polymeric coating.

Preparation of high porosity xerogels by chemical surface modification.

Patent Deshpande, Ravindra [51 Michelle Dr. Apt. A 11, Lancaster, PA 17603]; Smith, Douglas M [1412 Marquette Pl. NE., Albuquerque, NM 87122]; Brinker, C Jeffrey [14 Eagle Nest Dr. NE., Albuquerque, NM 87122]

This invention provides an extremely porous xerogel dried at vacuum-to-below supercritical pressures but having the properties of aerogels which are typically dried at supercritical pressures. This is done by reacting the internal pore surface of the wet gel with organic substances in order to change the contact angle of the fluid meniscus in the pores during drying. Shrinkage of the gel (which is normally prevented by use of high autoclave pressures, such that the pore fluid is at temperature and pressure above its critical values) is avoided even at vacuum or ambient pressures.

Metal halide solid-state surface treatment for nanocrystal materials

Patent Luther, Joseph M.; Crisp, Ryan; Beard, Matthew C.

Methods of treating nanocrystal and/or quantum dot devices are described. The methods include contacting the nanocrystals and/or quantum dots with a solution including metal ions and halogen ions, such that the solution displaces native ligands present on the surface of the nanocrystals and/or quantum dots via ligand exchange.

Group IV nanocrystals with ion-exchangeable surface ligands and methods of making the same

Patent Wheeler, Lance M.; Nichols, Asa W.; Chernomordik, Boris D.; ...

Methods are described that include reacting a starting nanocrystal that includes a starting nanocrystal core and a covalently bound surface species to create an ion-exchangeable (IE) nanocrystal that includes a surface charge and a first ion-exchangeable (IE) surface ligand ionically bound to the surface charge, where the starting nanocrystal core includes a group IV element.
