Scientific instrumentation solutions for emulsions and microemulsions sector

Acoustics makes possible measurement of Particle size of the emulsion and microemulsion droplets with no dilution, which is critical for these systems. Papers presented below indicate very good agreement between this method and independent data. Combination of Acoustics and Electroacoustics could reveal ...

Room Acoustics

"Good acoustics" is usually the target in room acoustics. The meaning of this depends on the type of room and the intended use. Rooms for musical presentations need a good sound quality at as many seats as possible while lecture halls demand good intelligibility of the teaching person. In case of open-space ...

Longitudinal Rheology

Propagation of a longitudinal stress wave through a visco-elastic media creates dissipation of mechanical energy, similarly to a shear stress wave. The rate of dissipation depends on two parameters: bulk viscosity and longitudinal viscosity. For ...

Sound instrumentation for building acoustics

The field of building acoustics consists of two parts; Room Acoustics which deals with sound propagation in a room and Building Acoustics, which deals with sound propagation between rooms. Typically, room acoustics is related to the quality of sound, e.g. concert hall acoustics, while building acoustics is ...

Particle Size Measurement

vary in size. Therefore, in order to adequately characterize such systems, it is not sufficient to simply determine a single particle size. We must instead determine the system’s particle size distribution. Measurements of the particle_size and particle size distribution are extremely important tools for ...
