In contrast to the well-established surface area, the average primary particle size of TiO2 has not been firmly established, with values of 20 30 nm.
He established analogous results for the sphere showing that the volume of a sphere is equal to that of a cone whose height equals the radius of the sphere and whose base equals its surface area; the surface area of the sphere he found to be four times the area of its greatest circle.
The more surface area the better.
Additional testing now is establishing the exact surface area of the inserted thin metallic surfaces and the residence time required to attain specific conversion efficiencies.
The system has the further merit that equilibria are established very rapidly due to the enormous surface area of the large number of semipermeable bags.
Let SA be the surface area of the suit, and SK the surface area of the skin.
The final weight of individual grains is the last of the yield components to be established once the number of spikes per surface area and the grain number per spike have already been fixed [[ 4]].
The bound ETGE peptide of Nrf2 adopts a β-turn conformation that inserts into this pocket to establish a buried surface area of 420 Å (Fig. 2A) [37], [37].
It also helped establish that greater surface area per mass predisposes nanoparticles to be more biologically active than larger-sized particles of the same chemistry; moreover, particle surface areas and number seem to be reasonably good predictors for nanoparticle-induced biological effects such as inflammation and oxidative stress responses.
Ecological corridors were established with the application of remotely-sensed impervious surface area in the ecological resistance surface evaluation.
A seal-less in-house ceramic housing was specifically designed and built to test the fuel cells and characterize their electrical performance as well as the thermal field established across the anode surface area.
