In polymer chemistry, a structural unit is a building block of a polymer chain.

It's a gas injected polymer chair.

Awkwardly for oil companies, bitumen is not ordinary oil.

They remove bitumen from the dirt in two ways.

Moreover, the newer bitumen technology does without strip mines.

Awkwardly for environmentalists, Nature put corrosive bitumen in the dirt.

Environmentalists make several arguments for leaving the bitumen in the dirt.

The companies want the bitumen that Nature put in the oily dirt.

This heats the bitumen, making it runny enough to be pumped out.

The companies want the bitumen that Nature put in the oily dirt.

Laying kilometer upon kilometer of bitumen is the favored solution for many politicians.

Another area I started thinking about involved creating new polymer materials.

US President Barack Obama has a limited opportunity to preserve the bitumen companies integrity.

This is an idea for a gas injected, one piece polymer chair.

Non polymer materials can also be used as the matrix for carbon fibers.

The tar sands are hundreds of square kilometers of bitumen, a viscous and corrosive tarlike deposit.

Many bitumen companies claim that they already abide by such safeguards but environmentalists skepticism is justified.

Our second concern was that for the country modified estimates, it was not possible to distinguish the slightly modified from the significantly modified estimates of indicators.

In the case of polymer nanocomposites we can use the properties of disordered systems.

There is a possibility of building ordered arrays of nanoparticles in the polymer matrix.

Carbon fiber reinforced polymer, carbon fiber reinforced plastic or carbon fiber reinforced thermoplastic (CFRP, CRP, CFRTP or often simply carbon fiber, or even carbon), is an extremely strong and light fiber reinforced polymer which contains carbon fibers.

Bitumen permeates the dirt at the surface or, where thin layers of compost and sediment intervene, somewhat below basement levels.

These cells are modified postganglionic neurons.

Organic semiconductors (polymer, oligomer) developed thus far have carrier mobilities below 10 cm2 (V s), and usually much lower.

Here recent developments in the field of polymer nano composites and some of their applications have been reviewed.

The polymer melt is usually produced by heating from either resistance heating, circulating fluids, air heating or lasers.

This is an interesting copolymer variant in that one of the ingredients was a polymer to begin with.

Mandatory sequestration could make net CO2 emissions from bitumen extraction no worse than those from conventional oil wells, and perhaps even better.

There are no GMOs Genetically Modified Organisms whatsoever.

This relatively simple process uses only one amide solvent, and therefore spinning can be done directly after the polymer production.

Genetically modified crops (GMCs, GM crops, or biotech crops) are plants used in agriculture, the DNA of which has been modified using genetic engineering techniques.

An older technology features vast strip mines, huge diggers, and trucks carting oily dirt to industrial scale pressure cookers that drain off the bitumen.
