The phrase "bulk was found" is correct and usable in written English.
It can be used when referring to a physical object being found. For example, "A large bulk of gold was found in the desert."
The origin of the unique photocatalytic activities of TiO2 nanoparticles comparing to the bulk is found in larger surface area and the existence of surface sites with distorted coordination.
Secondly, clear deviations in the temperature dependence of the mean squared displacement of the confined molecules compared to the bulk were found close to the thermal glass transition temperature, whereas localized methyl group rotations were only weakly influenced.
Both the difference in the degree of pyrene aggregation and the difference in micropolarity around pyrene molecules between the vicinity of the sapphire/polymer interface and the bulk were found to be quite common for these polymer films cast on sapphire plates, and are discussed in terms of the interaction between substrate surface and polymers.
Liquid membrane, designed in a form of the so-called bulk liquid membrane (BLM), was found to be the most suitable configuration for the treatment of calcium sulphate suspension.
However, the bifunctional bulk V2O5 was found to exhibit a much higher specific acidic catalytic activity than the acidic bulk Nb2O5 and Ta2O5, the latter being almost identical in their specific acidic catalytic activity.
At low anodic overpotentials, an increase in both mass and specific activities as a function of bulk composition was found up to 50 at.% Ru, corresponding to about 40% Ru on the surface.
For deviations larger than 15 (kg m−3), the determined bulk density was found to be not reliable and corresponding well sections were rejected during the evaluation of the bulk density and, thus, also for calculations of bulk porosity and the dynamic elastic parameters.
The bulk resistance was found to be decreasing with increasing % of PMMA in PVdF.
The bulk density was found to decrease with increasing Cr3+ content.
