Abstract:
The cetane number of middle distillate fuels may be increased using an additive composition including a polymer that may be a homopolymer or copolymer of olefins, and the like, where the polymer has a weight average molecular weight ranging from about 200,000 to about 5,000,000. The additive composition also includes a free radical initiator component, which may be an alkyl nitrate such as 2-ethylhexylnitrate (2-EHN), and/or a peroxide, such as t-butyl peroxide. In one non-limiting embodiment the amount of polymer in the additive composition is greater than the free radical initiator component. A solvent is also present, which the solvent may include alcohol, an alkyl substituted phenol and/or a heavy aromatic distillate.
Abstract:
An electric submersible motor is provided that includes a plurality of rotors and bearings mounted on a shaft, and a stator external to said rotors. A running clearance is located between an inner diameter of the stator and external diameter of the rotors, and includes a lubricating oil that includes a base hydrocarbon oil and a plurality of nanoparticles. Also provided is an improved lubricant oil and method of preparation thereof are provided. The lubricant oil includes a hydrocarbon containing base oil and a plurality of nanoparticles. The nanoparticles may be present in an amount up to 30% by volume.
Abstract:
The present invention is directed to a series of new compounds, combining the unique properties of fullerenes and bio-active amino acid residues, and to methods for making such compounds. The present invention is directed toward fullerene-based amino acids, and to amino acid residues, peptide chains, proteins, and polypeptides made from such fullerene-based amino acids. The present invention is further directed to amino acid residues, peptide chains, proteins, and polypeptides comprising such fullerene-based amino acids and into which such fullerene-based amino acids have been incorporated. Exemplary compounds have been prepared, and these compounds have been characterized and confirmed with infrared (IR) spectroscopy, nuclear magnetic resonance (NMR) spectroscopy, mass spectrometry (MS), etc. These new compounds, which are additions to the existing amino acid residue family, may potentially possess useful pharmaceutical application and may provide a new platform for further exploration in cancer therapy, and peptide and protein engineering.
Abstract:
The present disclosure provides an antimicrobial substrate including a substrate and a polythiophene polymer. The polythiophene polymer has a number of repeated monomer units from n is 5-14 or 30 to 120, a number average molecular weight (Mn) from 1,000 to 4,000 or 10,000 to 40,000; and a polydispersity index (PDI) from 1 to 1.3. The present disclosure also provides the polythiophene polymer and uses thereof.
Abstract:
Maleated fatty acids that are functionalized with materials such as polyols, alkanolamines and/or alkylene oxides have been discovered to improve the properties of various fluids. In a non-limiting example, functionalized maleated fatty acids having acid numbers less than 10 may improve the lubricity of fuels and lubricants, such as hydrocarbon fuels and lubricants, when added thereto.

Abstract:
A composition and method is described for intracellular delivery of fullerene containing peptides. The composition and method involve fullerene-substituted phenylalanine as part of a peptide based delivery system. The presence of a fullerene-substituted amino acid in a peptide is found to alter the intracellular transport properties of the peptide.
