Sentences with word «nanocrystalline»

Boland and colleagues showed for the first time that, in films of nanocrystalline copper just tens of nanometers thick, peaks and dips appear where misaligned grains meet.

And because cellulose is the most abundant organic compound on the planet, nanopaper has the potential to be cheaper than more - exotic, expensive - to - produce nanomaterials such as carbon nanotubes, says John Simonsen, a physical chemist and nanocrystalline cellulose expert at Oregon State University in Corvallis.

In the type of copper the researchers studied, nanocrystalline copper, the grains are particularly small; each has around 1 million atoms.

More specifically, some of the lower thermal conductivities in nanocrystalline materials have been achieved in materials that include hierarchically sized structures, at the atomic size, the nanoscale, and mesoscale, which can scatter phonons of various wavelengths and reduce phonon transport throughout the spectrum.

Her NQD research alone — published in series of 50 papers since 2000 and cited by other researchers more than 3,500 times — has had a significant international impact on the synthesis and elucidation of the underlying photophysical properties of nanocrystalline quantum dots through her discovery of giant NQDs.

In modern times, nanoparticles have emerged as a useful tool in medicine, with uses from providing the active ingredient in sunscreen (nano - scale particles of titanium dioxide), to stimulating blood vessel growth as an aid to healing, to delivering the key ingredients in artificial hearts (nanocrystalline zirconium oxide) and brain imaging (magnetic nanoparticles).

Nanocrystalline metals such as copper are widely used as electrical contacts and interconnects within integrated circuits.

Deshpande, S., Patil, S., Kuchibhatla, S. V. & Seal, S. Size dependency variation in lattice parameter and valency states in nanocrystalline cerium oxide.

Jennifer Hollingsworth has made remarkable accomplishments in defining, shaping and leading the field of core / shell semiconductor nanocrystalline quantum dots (NQDs), nanomaterials with unique optical emission properties and enormous technological ramifications in next - generation lighting and biological imaging applications.

Nanocrystalline cellulose (NCC), which is produced by processing wood pulp, is being hailed as the latest wonder material.

The reactions that break down the clays or carbonates stop the temperature from climbing higher, with heat being used up in the reactions that produce the nanocrystalline lubricant.

In such cases, the melt behaves like a lubricant and the sliding surface ends up covered with melt (that would quench to a glass) instead of the nanocrystalline lubricant.

• We misquoted Jeff Youngblood as saying that nanocrystalline cellulose is 2 nanometres long: it is 200 nanometres long (18...

In the melt spinning procedure however, crystallization is avoided: Either an amorphous structure is formed, in which the atoms are completely irregularly arranged, or a nanocrystalline structure, in which the atoms arrange themselves in nanometer - sized grains to form a crystalline structure.

The first layer of the film consisted of a nanocrystalline form of cobalt oxide that provided a stable, physically robust interface with the light - absorbing semiconductor.

The NC State research team combined lithium, magnesium, titanium, aluminum and scandium to make a nanocrystalline high - entropy alloy that has low density, but very high strength.
