As a proof of principle, we decided to synthesize a new family of biodegradable polymers, called polyanhydrides, for medical use.

Mental note to the liberators throwaway plastics take a lot of space and don't biodegrade.

Furthermore, the plastic and foil wrappers condoms are packaged in are also not biodegradable.

Shoes for Nike, where the uppers are polyesters, infinitely recyclable, the bottoms are biodegradable soles.

Breakdown of carbohydrates (e.g.

Bio polymer mass spectrometry software

Genetic engineering coupled with polymer physiotechnology coupled with xenotransplantation.

But I thought, no, no, experiment with resins, experiment with polymers.

Another graduate student showed that the polymers were safe.

Cells use the monomers released from breaking down polymers to either construct new polymer molecules, or degrade the monomers further to simple waste products, releasing energy.

Several common classes of enzymes digest these polymers.

In our world we use about 350 polymers to make all this.

And also, I thought that there would be synthetic polymers, plastics, embedded in the rock.

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

The polymers in mattress stuffing are used in breast implants.

This increase in entropy scales with the number of particles (or moles) being mixed.

Thus, concentrated solutions of polymers are far rarer than those of small molecules.

Nucleotides The two nucleic acids, DNA and RNA, are polymers of nucleotides.

Lignin and suberin are the only known biological polymers that are irregular.

These transfer proteins from the cytoplasm into the periplasm or into the environment around the cell.

Miscellaneous applications Nitric oxide can be used for detecting surface radicals on polymers.

We use five polymers in the natural world to do everything that you see.

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

Yet one of my graduate students synthesized the polymers for his doctoral thesis.

Heeger, A. J., Sinclair, M., et.al.

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

Polymer materials generally will form crystalline regions, but the lengths of the molecules usually prevent complete crystallization.

Any number of these monomer units may be indicated by the appropriate Greek prefix.

Polyurethane condoms in particular, given they are a form of plastic, are not biodegradable, and latex condoms take a very long time to break down.

In our first grant proposal, in 1981, the reviewers said that we would never be able to synthesize the polymers.

Effect of entropy Substances with extremely low configurational entropy, especially polymers, are likely to be immiscible in one another even in the liquid state.

Chemically, cellophane, rayon and cellulose are polymers of glucose and contain the chemical elements carbon, hydrogen and oxygen.

Working in a hospital, I saw that almost all polymers used in medicine were derived from household objects.

It was the first of a series of comprehensive organic and polymer science experiments sponsored by 3M Corporation.

The PM experiment was designed to observe the melting and resolidifying of different types of polymers while in orbit.

We returned the proposal for another review it came back with the comment that the polymers were fragile and would break.

Biochemistry Most proteins consist of linear polymers built from series of up to 20 different L α amino acids.

The Investigations into Polymer Membrane Processing (IPMP) experiment has flown previously on six Shuttle missions.

The A350 is the first Airbus with both fuselage and wing structures made primarily of carbon fiber reinforced polymer.

The Investigations into Polymer Membrane Processing experiment was conducted to determine the role convection currents play in membrane formation.

They are widely used to prevent the oxidative degradation of polymers such as rubbers, plastics and adhesives that causes a loss of strength and flexibility in these materials.

Matt Froind, a dairy farmer in New Canaan, Connecticut, who woke up one day and realized the crap from his cows was worth more than their milk, if he could use it to make these biodegradable flower pots.

As molecules such as polysaccharides, proteins, and nucleic acids comprise long chains of these small monomer units ( mono one mer part), the large molecules are called polymers ( poly many).

Solid polymer products start to crack on exposed surfaces as the material degrades and the chains break.

In the future they will look like that, because we need to move away from those type of polymers and use that for medical equipment and more important things, perhaps, in life.
