Nanoparticles of increasingly smaller particle size and various material compositions are being developed for the pharmaceutical, biomedical, electronics, optoelectronics, energy, catalyst and ...

A bimodal distribution often results from a process that involves the breakup of several sources of particles, different growth mechanisms, and large particles in a system. For instance, bimodal ...

Some particle size instruments, known as single particle counters, measure individual particle size, while others measure surface area as a function of particle size. Further instruments measure mass ...

The size distributions of ultra fine particles in diesel exhaust were measured in a dilution tunnel at a high dilution ratio, and the results were compared with roadside measurements. The size ...

Microscopic particles of dust, emitted into the atmosphere when dirt breaks apart, follow similar fragment patterns as broken glass and other brittle objects, according to new research. The research ...

Particle size analysis is used to characterize the size distribution of particles in a sample. This analysis can also be used to measure the particle size of solid materials, suspensions, emulsions, ...

Dynamic light scattering techniques are used to determine particle size distributions of protein therapeutic formulations. In DLS-based measurement, scattering intensity changes are associated across ...
