The use of long-chain alkenones to impart desired characteristics in personal care compositions for topical applications is described. The preparation of mixtures long-chain alkenones and synthetic derivatives thereof is presented. Examples of compositions include abrasive soaps, with alkenones serving as natural exfoliating agents. Alkenones and their derivatives can serve as emollients, occlusive agents, encapsulating agents, stabilizing agents, binding agents, thickening agents, surfactants, and antimicrobials.

Alkenone-based formulations for topical applications

A method comprising a series of selective extraction techniques for the parallel production of biodiesel and isolation of several valuable co-products including an alkenone hydrocarbon mixture of the kerosene/jet fuel range (primarily C10-, C12-, and C17-hydrocarbons) and fucoxanthin, a high-valued carotenoid, from the marine alkenone-producing microalgae

Use of marine algae for co-producing alkenones, alkenone derivatives, and co-products

In certain aspects, the disclosure provides methods for producing polymers from alkenone-producing algae, such as algae species of the Isochrysis family.

Use of marine algae for producing polymers

The present invention relates to the formation and processing of nanostructures including nanotubes. Some embodiments provide processes for nanostructure growth using relatively mild conditions (e.g., low temperatures). In some cases, methods of the invention may improve the efficiency (e.g., catalyst efficiency) of nanostructure formation and may reduce the production of undesired byproducts during nanostructure formation, including volatile organic compounds and/or polycylic aromatic hydrocarbons. Such methods can both reduce the costs associated with nanostructure formation, as well as reduce the harmful effects of nanostructure fabrication on environmental and public health and safety.

Alkyne-assisted nanostructure growth

The systems and methods described herein provide a scientific and analytical basis for the following: (a) collective interpretation of the entire spectrum of chromatographic data, e.g., GC&#xd7;GC two-dimensional data, with capability of operating at multi-resolution over bigger or smaller sub-regions of the two-dimensional data, (b) given two or more samples that are from the same source, and some samples from clearly different sources, quantitatively estimate where the fingerprint of the source lies, (c) given a source signature template, an unknown sample can be compared to decide whether it is related to, and if so, to what degree, to this source, and (d) given two source signature templates, the templates can be compared to determine how related is one source to the other.

Systems and methods for topographic analysis

The systems and methods described herein are directed toward the use of radiocarbon analysis techniques in the manufacture of biofuel products. Among other things, methods and systems for using measured fossil-fuel-derived carbon content in biofuel products to guide the design and modification of biofuel manufacturing systems are disclosed.

Biofuel manufacturing methods and systems incorporating radiocarbon analysis techniques

A method of estimating contamination of oil based mud filtrate in a hydrocarbon sample. The method comprising the steps of obtaining a hydrocarbon sample contaminated with oil based mud filtrate, then analyzing the contaminated hydrocarbon sample using two-dimensional gas chromatography (GC&#xd7;GC). The method further comprises identifying one or more unique component or tracer in the oil based mud filtrate in the contaminated hydrocarbon sample. Finally, the method comprises of summing the peak volumes of the one or more unique component or tracer, relative to the peak volumes of a clean hydrocarbon sample.
