Super-Hydrophobic Multi-Walled Carbon Nanotube Coatings for Stainless Steel
We have taken advantage of the native surface roughness and the iron content
of AISI 316 stainless steel to direct grow multi-walled carbon nanotube (MWCNT)
random networks by chemical vapor deposition (CVD) at low-temperature (C), without the addition of any external catalysts or
time-consuming pre-treatments. In this way, super-hydrophobic MWCNT films on
stainless steel sheets were obtained, exhibiting high contact angle values
() and high adhesion force (high contact angle hysteresis).
Furthermore, the investigation of MWCNT films at scanning electron microscopy
(SEM) reveals a two-fold hierarchical morphology of the MWCNT random networks
made of hydrophilic carbonaceous nanostructures on the tip of hydrophobic
MWCNTs. Owing to the Salvinia effect, the hydrophobic and hydrophilic composite
surface of the MWCNT films supplies a stationary super-hydrophobic coating for
conductive stainless steel. This biomimetical inspired surface not only may
prevent corrosion and fouling but also could provide low-friction and
drag-reduction.Comment: 6 pages, 3 figure
Exploiting the Hierarchical Morphology of Single-Walled and Multi-Walled Carbon Nanotube Films for Highly Hydrophobic Coatings
Self-assembled hierarchical solid surfaces are very interesting for wetting
phenomena, as observed in a variety of natural and artificial surfaces. Here,
we report single-walled (SWCNT) and multi-walled carbon nanotube (MWCNT) thin
films realized by a simple, rapid, reproducible, and inexpensive filtration
process from an aqueous dispersion, that was deposited at room temperature by a
dry-transfer printing method on glass. Furthermore, the investigation of carbon
nanotube films through scanning electron microscopy (SEM) reveals the
multi-scale hierarchical morphology of the self-assembled carbon nanotube
random networks. Moreover, contact angle measurements show that hierarchical
SWCNT/MWCNT composite surfaces exhibit a higher hydrophobicity (contact angles
of up to 137{\deg}) than bare SWCNT (110{\deg}) and MWCNT (97{\deg}) coatings,
thereby confirming the enhancement produced by the surface hierarchical
morphology.Comment: 7 pages, 5 figures, This article is part of the Thematic Series

Seismic analysis of fault damage zones in the northern Tarim Basin (NW China):Implications for growth of ultra-deep fractured reservoirs
Understanding fault damage zone is of significant importance for the characterization and modeling of ultra-deep (greater than 6000 m) fractured reservoirs. However, seismic detection of fracture networks in deep fault zone it is still challenging. For this contribution, we propose a seismic Tensor Thickness Method for optimal imaging of the ultra- strike-slip fault damage zones in the Tarim Basin. The results show reasonable distinction through seismic methods of boundary of fault damage zones in carbonate host rock that is consistent with the fractured reservoirs constrained from borehole data. In addition, this study suggests that fault damage zones in ultra deep settings exhibit width ranging 100–800 m, with a linear correlation between fault damage zone width and throw. Isolated fault zones are characterized with linear relationship between the width and displacement of the strike-slip fault zones, but the abnormally wide fault damage zone is likely attributed to fault interaction and overlapping. The results of this work are applicable for fractured reservoir characterization in deep and tight carbonate rocks elsewhere
