Abstract:
Provided herein are fullerene compositions, and methods of preparing thereof. More particularly, the fullerene compositions comprise a fullerene-polymer complex comprising a fullerene and a non- conjugated hydrophilic or amphiphilic polymer, wherein the non- conjugated polymer is substituted with a substituent comprising a functional group capable of forming intermolecular interactions with the fullerene via pi-stacking.
Abstract:
Process and apparatus for separating fullerenes from a solid mixture of fullerenes at different molecular weight and amorphous carbon (commonly named soot), in order to let available one or more types of pure fullerenes, that may be used in different industrial application fields of the technique, like the chemical, electronic, mechanic, automotive, biologic, medical, construction industry, the separating process of fullerenes regarding preferably fullerenes the molecules of which are composed preferably of 60 or 70 carbon atoms.
Abstract:
A nuclear fuel element for use in a nuclear reactor may include a plurality of metal fuel sheaths extending along a longitudinal fuel element axis and spaced apart from each other, the plurality of fuel sheaths comprising a first fuel sheath having an inner surface, an opposing outer surface and a hollow interior configured to receive nuclear fuel material. A carbon coating may be on the inner surface of the first fuel sheath. The carbon coating may include more than 99.0%wt of a carbon material including more than 20%wt of carbon nanotubes and less than about 0.01 %wt of organic contaminants.
Abstract:
A molecular species is covalently attached to elemental carbon by exposing the carbon to a reaction mixture containing a strong base and a compound of the formula (I) or (II) in which X denotes a covalently attached atom or group capable of forming an X- anion and each Z is a moiety comprising a plurality of atoms, but which does not have a hydrogen atom directly attached to the atom which itself is directly attached to the -CH2X or -CHX group. The carbon substrate may be graphite or carbon nanotubes.
Abstract:
A composition and method for fabricating graphitic nanocomposites in solid state matrices is presented. The process for fabricating graphitic nanocomposites in solid state matrices may include selecting one or a mixture of specific graphitic nanomaterials. The graphitic nanomaterial(s) may be functionalizing with a moiety similar to the building blocks of the solid state matrices. The functionalized graphitic nanomaterials are mixed with the building blocks of the solid state matrices. The mixture may be cured, which causes in situ formation of the sol-gel solid state matrices that entraps and/or covalently links with the graphitic nanomaterials during the network growing process. This process allows the nanomaterials to be introduced into the matrices homogeneously without forming large aggregations.
Abstract:
some embodiments, a lipofullerene-saccharide compound and a method of inhibiting and/or ameliorating metastasis of neoplastic cells using said compound is disclosed herein. The lipofullerene-saccharide compound may be used in therapeutically effective doses to inhibit the metastasis of neoplasms in mammals. some embodiments, the method may include administering to a subject an effective amount of a pharmaceutically acceptable formulation including a lipofullerene-saccharide compound. In some embodiments, the lipofullerene-saccharide compound may be formed by reacting (e.g., coupling) a lipid and a saccharide with a fullerene. some embodiments, neoplastic cells may include pancreatic cancer cells, prostate cancer cells, lung cancer cells, breast cancer cells, colon cancer cells, and/or brain cancer cells. A significant anti-metastatic effect has been observed on a metastatic nude-mouse model of human pancreatic cancer BxPC-3 cell lines constructed orthotopically as a result of therapeutic treatment with the lipofullerene-saccharide conjugate.
