Chromium-catalyzed production of alcohols from hydrocarbons in the presence of oxygen
Processes for converting a hydrocarbon reactant into an alcohol compound and/or a carbonyl compound are disclosed in which the hydrocarbon reactant and either a supported chromium (VI) catalyst or a supported chromium (II) catalyst are contacted, optionally with UV-visible light irradiation, followed by exposure to an oxidizing atmosphere and then hydrolysis to form a reaction product containing the alcohol compound and/or the carbonyl compound. The presence of oxygen significant increases the amount of alcohol/carbonyl product formed, as well as the formation of oxygenated dimers and trimers of certain hydrocarbon reactants.
MATERIALS COATED WITH CALIXARENES
This invention relates to the direct grafting of a calixarene mostly onto the surface of a material, as well as to a grafting process, and certain calixarene intermediates useful for carrying the grafting process.
RETINOIC ACID RECEPTOR ANTAGONISTS AS CHAPERONE-MEDIATED AUTOPHAGY MODULATORS AND USES THEREOF
Compounds, compositions and methods are provided for selectively activating chaperone-mediated autophagy (CMA), protecting cells from oxidative stress, proteotoxicity and lipotoxicity, and/or antagonizing activity of retinoic acid receptor alpha (RAR) in subjects in need thereof.
Recyclable metathesis catalysts
Highly active, recoverable and recyclable transition metal-based metathesis catalysts and their organometallic complexes including dendrimeric complexes are disclosed, including a Ru complex bearing a 1,3-dimesityl-4,5-dihydroimidazol-2-ylidene and styrenyl ether ligand. The heterocyclic ligand significantly enhances the catalytic activity, and the styrenyl ether allows for the easy recovery of the Ru complex. Derivatized catalysts capable of being immobilized on substrate surfaces are also disclosed. The present catalysts can be used to catalyze ring-closing metathesis (RCM), ring-opening (ROM) and cross metatheses (CM) reactions, and promote the efficient formation of various trisubstituted olefins at ambient temperature in high yield.
Materials coated with calixarenes
A calixarene directly grafted onto the surface of a material, a related grafting process, and certain calixarene intermediates useful for carrying out the grafting process.
Polyfunctional sorbent materials
Disclosed herein is a material comprising a functionalized solid support surface, wherein the functionalization comprises a thioalkylene linker bound to the support surface and the thioalkylene linker is coupled to a moiety derived from a ligand, wherein the ligand includes a terminal alkenyl and at least one first functional group configured to bind to at least one predetermined target species.
Dark quenchers for donor-acceptor energy transfer
The present invention provides a family of dark quenchers, termed Black Hole Quenchers (BHQs), that are efficient quenchers of excited state energy but which are themselves substantially non-fluorescent. Also provided are methods of using the BHQs, probes incorporating the BHQs and methods of using the probes.
MASSIVE PARALLEL METHOD FOR DECODING DNA AND RNA
This invention provides methods for attaching a nucleic acid to a solid surface and for sequencing nucleic acid by detecting the identity of each nucleotide analogue after the nucleotide analogue is incorporated into a growing strand of DNA in a polymerase reaction. The invention also provides nucleotide analogues which comprise unique labels attached to the nucleotide analogue through a cleavable linker, and a cleavable chemical group to cap the OH group at the 3-position of the deoxyribose.

Superficially porous particle (SPP) chiral phases for liquid chromatography
The present invention relates to a novel stationary phase support for liquid chromatographic chiral separations. The specific combination of the special underlying support material and certain classes of known chiral selectors according to the invention produces far superior chiral (enantiomeric) separations than those obtained on any conventionally known supports. These chiral (enantiomeric) separations are enhanced in terms of significantly higher efficiencies (theoretical plate numbers), higher resolutions (R.sub.s), shorter retention times and either equivalent or slightly higher selectivities than those obtained on conventional supports.
