Sentence examples for excessive surface area from inspiring English sources

It indicates that not only the excessive surface area but also the synergistic effect of nickel and cobalt plays an important role in the enhancement of HER.

Several electrodes with excessive surface area have been reported in recent years, such as the commercial Raney type electrodes [3, 4, 5], anodic aluminum oxide-assisted electrodeposited Ni nanowires [4], SnO2 hierarchical architectures [5], double-template electrodeposited three-dimensional porous nickel [6], and so on.

The enhanced i 0 of the Cu/Ni nanostructured electrode can be mainly ascribed to the excessive specific surface area of the hierarchical structures and the facile vectorial electron transport along with a great amount of nanometric "steps," which is derived from the process of crystal growth.

The excessive increase in specific surface area of catalyst may not lead to decrease in activation overpotential or increase in DGFC performance in the region of limited glucose flux in the catalyst layer.

Therefore, the catalyst precursor showed a high specific surface area, while excessive Fe or Mg had negative effect on the catalytic property and performance.

This can be seen when the O2 gradient is low due to a deficit in utilization (for example, from mitochondrial blockage, cyanide poisoning, and so on) and/or when O2 tissue diffusion is impaired by an excessive distance or a reduced surface area (for example, in the presence of edema, inflammation, microclots, reduced capillary density, anatomical and/or functional shunts).

The best matches required either using unrealistically high illite in the sandstone (higher than in the shale) or alternatively excessive high quartz surface areas (which were also higher than in the shale).

However, Si-based solar cells are not convenient because of excessive fabrication costs, requirements of large surface area and their limited functionality in the absence of sunlight.

Nasal resistance increased and the wall heat transfer decreased in model (3) due to sudden airway expansion and excessive reduction of the mucosal wall surface area.

Other desirable morphologies involve one-dimensional nanostructures, like nanorods and nanowires, which can offer a small diameter to enhance lithium diffusion and yet still provide a limited surface area to prevent excessive side reactions [18].

The selection of the most appropriate carburization conditions is necessary to avoid excessive coke deposition and sintering of the active surface area that could lead to loss of catalyst activity.
