Process considerations for nanostructured coatings

Some features of query construction in an expert system according to the peculiarities of knowledge structuring (using the domain of nanotechnology as an example)

“…(2) Nanofiber -nano-object (flexible or rigid) with two external dimensions in the nanoscale and the third dimension significantly larger [Trotta, Mele 2019].…”

Safe nanomaterials: from their use, application, and disposal to regulations

“…59 The increased active surface area of NPs has also been exploited in catalysis and energy-conversion systems. 60 The industry of paintings and coatings have applied NMs in recent years, looking for the improvement of various properties such as anticorrosion, durability, biodegradability, antimicrobial properties, 61 and waterproong in textiles 62 addressing the objective 9 industry innovation and infrastructure. NMs have been used for coatings on sealed porous surfaces with a thinner layer, and various companies have applied those and other properties to commercial products.…”

Entropy Analysis of a Convective Film Flow of a Power-Law Fluid with Nanoparticles Along an Inclined Plate

“…We note that n> 1 corresponds to dilatant nanofluids and n < 1 to pseudo-plastic nanofluids. It is also noteworthy that the momentum boundary layer problem defined by the ordinary differential equations (7) and (8) subject to the relevant boundary conditions (11)-(12) is decoupled from the thermal and nanoparticle boundary layer equations. Although the hydro-dynamical problem admits similarity solutions, the accompanying thermal and nanoparticle volume fraction problem does not, since the governing equations (9) and (10) for the temperature and nanoparticle volume fraction field exhibits explicit dependencies on both  and .…”

“…Nanofluids were introduced by Choi [6] in the 1990s and have been applied in a diverse range of engineering systems including medical, energy and materials sciences. An important area of interest has been nano-coatings [7] in which thin nano-structured films are deposited on surfaces which require protection from corrosion, abrasion, degradation, acidic attack etc. Phan et al [8] have deployed nanofluid coatings to improve surface wettability in phasechange heat transfer.…”

“…The objective of the present paper is to investigate the entropy generation in natural convection thin film boundary layer flow of an Ostwald-de Waele power-law nanofluid along an inclined plate. The viscous incompressible nanofluid model developed by Buongiorno [7] (which includes the effects of Brownian motion and thermophoresis), is revised so that the nanofluid particle fraction (concentration) on the boundary is passively rather than actively controlled.…”
