nanotechnology

[-teknol′əjē]
technology at the level of atoms, molecules, and molecular fragments, including manipulating them and creating new structures.

nanotechnology

(nă″nō-tĕk-nŏl′ŏ-jē) [L. nanus, dwarf, + Gr. technē, art, + logos, word, reason]
The scientific study and engineering of chemical or biological objects measuring between 1 and 1000 nanometers. Objects this small are about the size of atoms or small molecules. “Wet” nanotechnology is the manipulation of organic or biological compounds in solution. “Dry” nanotechnology is the engineering of objects on silicon or carbon surfaces, such as those used in computing.

nanotechnology

The application of the science of manipulation at an atomic level. The practical applications of the ability to move single atoms so as to construct molecules, materials, structures and even functioning machines at an atomic level. Nanotechnology is currently at a germinal stage but is expected to have extensive applications in medicine. See also MAGNETIC NANOPARTICLES.

A nanorefrigerant is one kind of solid-liquid mixture, but experiments show that the classical models for a solid-liquid mixture's thermal conductivity, such as the Maxwell model, Bruggeman model, CSM model, Rayleigh model, Monecke model, and Cichocki-Felderhof model, are not applicable for nanofluids (Wang et al.

While we know Flotek's Complex nano-Fluid chemistries have been successful in enhancing production in tight resource formations, we believe a more complete understanding of the interaction between our chemistries and geologic formations as well as a more precise comprehension of the physical properties and impact of our nanofluids in the completion process will significantly enhance the efficacy of the unconventional hydrocarbon completion process.
