Field emission SEM revealed nodular deposits with moderate surface roughness.
In this study, it is considered: (a) the effect of the exchange current density to the limiting diffusion current density ratio (j0/jL) at low level of surface coarseness on the polarization characteristics of the electrochemical process, (b) the effect of the shape of surface protrusions on the electrode surface roughness, and (c) the effect of surface roughness on the j0/jL ratio.
Surface coarseness dictates the strength of nanoparticle-cell interactions and promotes cell adhesion.
Using their whiskers, rats can reliably detect small differences in surface coarseness (Guic-Robles et al., 1989; Carvell and Simons, 1990).
These findings indicate that layer 2 3 neurons perform high hierarchical processing of tactile information, with surface coarseness embodied by distinct neuronal subpopulations that are spatially mapped onto the barrel cortex.
In the granular and infra-granular cortical layers of the barrel cortex neurons mostly respond to stick and slip events, and surface coarseness has been shown to be coded for the most part by the average spike count in the neuronal population.
We compared the response of neurons to the different textures (sandpapers P120, P320, P600, P1000) and found that only a small minority of neurons showed either monotonically increasing or decreasing responses with surface coarseness (Romo and Salinas, 2003; Arabzadeh et al., 2005; von Heimendahl et al., 2007; Diamond et al., 2008b).
Most of the commercially available orthopedic implants have a moderate surface roughness.
S-14 with moderate SiO2/Al2O3 surface treatment was made the reference standard.
Examiners were instructed to rank subjects separately for active caries and for filled surfaces as 0, no decayed or filled surfaces; 1, mild (1 2 affected surfaces); 2, moderate (3 6 affected surfaces); and 3, severe (>6 affected surfaces).
