Compositions comprising a continuous phase of at least one polypropylene; within the range of from 5 wt % to 50 wt % of a mineral hydroxide filler by weight of the composition, having an aspect ratio within the range of from 5 or 6 or 8 to 20 or 40 or 100 or 200 or 800 or 1000; and within the range of from 5 wt % to 40 wt % of a olefin block-containing copolymer by weight of the composition. Also described is a method of forming the compositions comprising combining the components as 'masterbatches' or as neat ingredients, or some combination thereof.

Polypropylene compositions and methods to produce the same

A method for improving wear control, while maintaining or improving fuel efficiency, in an engine or other mechanical component lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition including a lubricating oil base stock as a major component, and (i) at least one transition metal salt of a carboxylic acid (e.g., zinc stearate) or (ii) a mixture of at least one transition metal salt of a carboxylic acid (e.g., zinc stearate) and at least one detergent (i.e., an alkali metal or alkaline earth metal salt of an organic acid, or an alkali metal or alkaline earth metal salt of an inorganic acid, or an alkali metal or alkaline earth metal salt of a phenol, or mixtures thereof (e.g., calcium salicylate and/or magnesium sulfonate)), as a minor component. The lubricating oils are useful in internal combustion engines.

Alternating crystalline-amorphous polyolefin based multiblock copolymer compositions and methods for producing these multiblock copolymer compositions are disclosed. Also disclosed is the use of these multiblock copolymer compositions as additives to high density polyethylene (HDPE) resins in order to form polymer blends having improved ductility and toughness over that of the HDPE resins while retaining high mechanical strength, and the use of these polymer blends in films.

Mechanical oscillators employ the use of resonance parameters, frequency and the quality factor Q, for the measurement of corrosion or deposition. The ability of a mechanical oscillator to measure small amounts of metal loss or deposition is not only dependent upon the mechanical design but is limited by the precision in determining the resonance frequency and Q. Methods for measuring these resonance parameters with a high precision in the presence of noise are provided. The increased degree of precision improves the utility of these devices as sensitive probes for corrosion and deposition (fouling) measurement. The increased degree of precision is enabled in part by employing curve fitting consistent with modeling the mechanical oscillator as a simple harmonic oscillator. This curve fitting procedure, combined with averaging and utilizing signal processing parameters to mitigate noise effects, adds precision in measuring resonance parameters.

Determining the resonance parameters for mechanical oscillators

This invention relates to a microcantilever stress sensor for detecting and quantifying low levels of contaminants in liquids and gases. The invention uses a chemical agent to impart chemical specificity to the microcantilever stress sensor. The microcantilever deflects when the chemical agent is replaced by a more strongly adsorbing chemical species. The magnitude of the deflection is then used as a measure of the quantity of contaminant present.
