The neutrons are created in a fission reactor, and slowed to incredibly low speeds by materials known as moderators.
The method used to attach the polyethylenimines to materials is also well known the bonding agent benzophenone has already been used to attach the anti-microbial agent to glass, polymer, paper, and metal.

Conducting polymers are known as intelligent materials with the unique behaviour of trapping an ion into their structure and release the ion by an electric potential.
Scientists have known that other materials can hold more lithium ions and increase the amount of energy that can be packed into a cell.

The new materials are based on a design known as the "split ring" structure.
Now that this data has been collected, it can be analysed and compared with the known spectral signatures of materials likely to be found in comets.
It has long been known that some solid materials, called metal hydrides, are capable of storing small amounts (about 1-2% of their own weight) of hydrogen at room temperature.
There is still no approval for U.S. cargo planes filled with drinking water and other aid materials to land inside Myanmar, also known as Burma.
Little is known in terms of what exact materials make up an asteroid.
Terahertz waves are known for their ability to penetrate materials without damaging them, and have in recent years been added to the suite of tools used to examine items of cultural heritage.
In an age that lived precariously on credit, Phyfe always paid cash for his materials, laying in sufficient quantities of mahogany timber known as "Phyfe logs" to allow the sawed lumber to season far longer than was usual.

The artist, who had been in poor health since 2007, was known for his sprawling works that sometimes featured discarded everyday materials.
Many of the known thefts or attempted thefts of the most dangerous nuclear materials have taken place in Russia and other parts of the former Soviet Union.
Until now, these have relied on what are known as "metamaterials" - artificially-produced materials that have microscopic variations in their properties that guide incoming light waves around or over a hidden object.
Government support, the state of the world aviation industry, the price of oil, customer support, World Trade Organization rulings, the speed of technological progress in composite materials, the reaction of industry behemoths Boeing and Airbus are all known unknowables which cause considerable uncertainty to the board of Bombardier.
Although the maker of semiconductor manufacturing equipment originally guided for quarterly results between breakeven and 4 cents a share, Applied Materials said the original forecast didn't account for charges, which weren't known at the time.
Scientists have known for some time that nanowires can trap more light, and using certain materials, such as gallium arsenide, can make use of a certain section of the light spectrum that significantly increases energy production.

Continue on to the Corniche to stroll with locals as the sun sets, and wander over to watch the last rays catch the imposing Sheikh Zayed bin Sultan Al Nahyan Mosque, probably Abu Dhabi's most important landmark, known as the "Grand Mosque" to locals, and whose lavish buildings materials hark from as far afield as Greece, Italy, Morocco and Germany.
In fact levels are known to vary widely within even small areas, depending on weather patterns and building materials.
