Superfilling the gaps in VA-MWNTs with copper to produce a void-free Cu/VA-MWNT film is mainly based on the competitive diffusion and adsorption of polyethylene glycol and bis- 3-sulfopropyl) disulfide that leads to a peculiar kinetic profile decreasing from the bis- 3-sulfopropylof the gaps.
The detonation of a chemical explosive under a runway produces a void and may change the stiffness in subgrade zones.
It was found that incorporation of 20 wt% PVP into the PEG produced a void-free, high quality Ti-MIM component, with an average final density of 98% and a tensile elongation of 9.5%.
In order to minimize density variations and void ratio non-uniformities within a specimen, the undercompaction technique introduced by Ladd (1978) was employed to produce a relatively uniform void ratio throughout the specimen height.
For a given density, although the additives in combination led to increased void numbers, higher strength was achieved due to reduced void size and connectivity, by preventing their merging and producing a narrow void size distribution.
We describe a simple method to prepare nanostructured copper electrodes based on electrodeposition of copper through a polystyrene nanosphere template to produce a copper sphere segment void (SSV) structure.
The studied soil samples are predominantly by more or less smoothed grading curves that produce a considerable amount of voids between their particles (Fig. 4).
The participants produced a freshly voided morning urine sample as soon as possible after the day of diagnosis (median time from diagnosis to urine sample was 11 days; interquartile range, 4 29 days).
Hence, drawing on the pragmatic spirit that inspired the first publication of the consensus statement on antithrombotic prophylaxis in hip and knee replacement surgeries and femoral head fractures [2], the intersociety working group decided to fill the void and produce a document more useful for clinical practitioners, as the previous one.
Our results also show that large scale surface defects, such as voids, could produce a similar effect than size reduction in improving the catalytic performance of the nanorod, thus avoiding undesirable amorphization instabilities, which are inevitable at reduced sizes.
