Fine coal cleaning is difficult and costly. Two different technologies have been considered. One is froth flotation, such as Microcel, and the other is oil agglomeration. The latter is better in terms of separation efficiency. But the cost is high due to the large oil consumption. ...

Phenol/formaldehyde resins are important group of polymeric materials (thermosets) prepared by reacting petroleum derived phenol with formaldehyde to form either novolacs or resols which have extensive applications in the wood and other industries. The new invention replaces 90 wt% of the petroleum derived phenol with fractional catalytic pyrolysis oils ...

An n-type and p-type silicone optical fibers have demonstrated. The fiber is fabricated by drawing from a powder-in-tube type perform. Outside Diameters in the range of several hundred microns have been made with core diameters in the range of tens of microns. Fibers fabricated have a polycrystalline ...

The technology is artificial muscle designed to be functional and replace lost muscle while allowing new muscle to regenerate. This nanofiber can be placed in to intricate scaffolds for the muscle replacement. These scaffolds can be designed to have the same shape as real muscle while contracting like ...

The present inventions are concerned with methods of improving corrosion protection for metals, particularly for galvanized steel sheets. The improvements are brought about by:

1) adding sulfur-containing compounds to polymeric coating material (or resin) and,

2) adding sulfur-containing compounds such as thiols on metal substrates, particularly galvanized steel.

Typically, the galvanized steel ...
