Those are called the asphaltenes they're an ingredient in asphalt.

The asphalt will burn.

And then the asphaltenes and this is the crucial thing the asphaltenes get whipped by the waves into a frothy emulsion, something like mayonnaise.

In general, more than 50 percent of roads are untarred.

Nigeria 70 percent of roads are untarred. Zambia 80 percent.

30. Pitcairn s 6.4 kilometres of roads are unpaved.

Of molten pitch shall be their garments, their faces covered with flames,

Their cloaks will be of pitch and fire will cover their faces.

of pitch their shirts, their faces enveloped by the Fire,

Their trouser hell be of pitch, and the Fire shall cover their faces.

Their garments will be of pitch, and fire will cover their faces.

Their garments made of tar, and the Fire covering their faces.

their garments shall be black as if made out of pitch, and flames of the Fire shall cover their faces

When that moves into polymers, you can change the elasticity, the fluidity of the form.

So these guys were in a worker's gang mixing up asphalt one morning on the side of the highway.

The other big dynamic of change is the sheer performance of underperforming asphalt.

The first step was to select monomers a polymer s building blocks that would be safe in the human body. We then synthesized these polymers and discovered that by changing their composition, we could make them last in the body for a period ranging from days to years.

We're a small but prosperous town, yet we allow tarpaper shacks to stand.

And that's a plastic polymer.

79. Conductive polymers can change colour and conductivity in response to chemical and electronic stimuli.

Bio polymer mass spectrometry software

Smart material types include piezoelectric polymers, conductive polymers, piezoelectric and electrostrictive ceramics, electrorheological fluids, magnetorheological fluids, electrochromic coatings, magnetostrictive materials, micromachined integrated devices, and biomimetic polymers and gels, shape memory alloys and polymers.

This is made bone is made from a mixture of inorganic minerals and polymers.

And by presenting a really strong economic case, they convinced the L.A. government that replacing that asphalt with trees and other greenery, that the schools themselves would save the system more on energy than they spend on horticultural infrastructure.

People look at the roads, for example, and they'd say, Angola 90 percent of roads are untarred. Ah, problem!

Young people widely agree that youth developed, youth friendly educational programmes and policies are effective in convincing young people of the harm caused by substances.

It's a high strength polymer.

An older technology features vast strip mines, huge diggers, and trucks carting oily dirt to industrial scale pressure cookers that drain off the bitumen. A newer technology leaves the surface untouched by pumping steam into the subsoil.

71. Polymer matrix composite technology is currently more mature than CMC technology.

Bitumen permeates the dirt at the surface or, where thin layers of compost and sediment intervene, somewhat below basement levels. Grasping a handful of dirt from a riverbank does leave one s hand more oily than tarred, and the greasy dirt is somewhat sandy.

Supramolecular assemblies 82. Both natural and synthetic polymers can be designed to form large assemblies of molecules with useful properties.

It's a gas injected polymer chair.

I design for that condition, biopolymers. It's the future.

It's a bio polycarbonate new chair I'm doing in Italy.

More widespread use of PMCs will require better capability to predict long term performance and more cost effective fabrication methods.

And Andy and his team discovered that they were going to spend 200 million of those dollars on asphalt to surround the schools themselves.

We particularly welcome the presence of young people at the United Nations today, as well as the aspirations they are expressing.
