Sentence examples for particles are difficult from inspiring English sources

Fine particles cause clogging and larger particles are difficult to be efficiently deposited.

As is well known to mineral processing scientists and engineers, fine and ultrafine particles are difficult to float mainly due to the low bubble-particle collision efficiencies.

For physical surface modification of a complex workpiece, the incoming particles are difficult to arrive at the inclined surface of the complex workpiece due to self-shadowing effect.

In particular, photo-curable resins reinforced by metal particles are difficult to process, because of fundamental limitations related to the high reflectivity of intermetallics in the UV visible range.

Fig. 6 Graphite nanoparticles: individual particles are difficult to identify from the agglomerates and the contrast formation due to the inner structure of the particles complicates the analysis further.

At the same time, the selection process takes advantage of non-microscopic methods when particles are difficult to discern from the background (e.g., low relative contrast), have broad and multimodal distributions, and when reasonably equiaxed and uniform materials are present with few small aggregates.

Fluidized bed containing fine particles is difficult to operate due to high cohesive force.

The kinetic performance of graphite particles is difficult to deconvolute from half-cell experiments, where the influences of the working electrode porosity and the counter electrode contribute nonlinearly to the electrochemical response.

The distribution of particles is difficult to control and often the specific surface area is used instead.

Since the particle size can be tuned by varying the parameters for the chemical synthesis routes, comparing the final functionality of the particles is difficult.

However, the aggregation of colloidal particles is difficult to control, thus leading to poor reproducibility of both substrates and SERS signals [12, 13].
