摘要:A novel metal-organic framework (MOF) templated process for the synthesis of highly porous inorganic sorbents for removing radionuclides, actinides, and heavy metals is disclosed. The highly porous nature of the MOFs leads to highly porous inorganic sorbents (such as oxides, phosphates, sulfides, etc) with accessible surface binding sites that are suitable for removing radionuclides from high level nuclear wastes, extracting uranium from acid mine drainage and seawater, and sequestering heavy metals from waste streams. In some cases, MOFs can be directly used for removing these metal ions as MOFs are converted to highly porous inorganic sorbents in situ.

标题:Greener Synthesis of Nanoparticles Using Fine Tuned Hydrothermal Routes
发明人：MAYE MATHEW
权利人:MAYE MATHEW; UNIV SYRACUSE
摘要:The synthesis of energy and sensor relevant nanomaterials that involves the colloidal synthesis of quantum dots (e.g. CdSe, CdS, ZnS, CdSe/ZnS) under well-controlled hydrothermal conditions (100-200 degrees C.) using simple inorganic precursors. The resulting nanomaterials are of high quality, and are easily processed depending upon application, and their synthesis is scalable. Scalability is provided by the use of a synthetic microwave reactor, which employs dielectric heating for the rapid and controllable heating.

摘要:The present invention relates to an improved process for the large scale synthesis of cyclic heptapeptide using Fmoc solid phase synthesis technique. The described process assembles the peptide on a solid support resin by coupling to one another by peptide bonds to obtain a peptide wherein the coupling of cysteine to the resin employs a combination of solvents to reduce cysteine racemization. The process described relates to the use of C1-C4 alcohols as total substitute to organic nitriles thus making the process cost effective, non-toxic and eco-friendly.

摘要:Present invention describes a method for synthesis of O-glycosylated amino acid or peptide or derivatives thereof, characterized by the use of a glycosyl donor which is a monosaccharide in pyranose or furanose form or which is an oligosaccharide, and by the use of an acceptor which is a hydroxyl group containing amino acid or peptide derivative which has been modified in its N-terminal α-amino group and in which the C-terminal carboxyl group is non-modified, employing an exo- or an endoglycosidase (EC 3.2) as catalyst in an equilibrium reaction and that the product is isolated from the reaction mixture or is used directly or after partial or complete isolation in a continued synthesis with chemical methods or with enzymatic methods.
