Magnetic resonance imaging (MRI) provides a powerful tool to evaluate the effectiveness of process equipment during operation. We discuss the use of MRI to visualize mixing in a static mixer. The application is relevant to personal care products, but can be applied to a broad range of food, chemical, biomass and biological fluids.

There are technical obstacles to measuring current flux through multiple ion channels simultaneously, and later discerning what portion of the transmembrane current is due to each channel type. To address this need, this method presents a way to generate the IV curve of individual channel types using specific frequency components.

The Lewis structure of a nitrite anion (NO2−) may actually be drawn in two different ways, distinguished by the locations of the N-O and N=O bonds. If nitrite ions do indeed contain a single and a double bond, the two bond lengths are expected to be different. A double bond between two atoms is shorter (and stronger) than a single bond between the same two atoms. However, experiments show that both N–O bonds in NO2− have the same strength and length, and are identical in all other...

FAQs
A resonance peak identifies a frequency region where the measured response becomes especially large relative to nearby frequencies. Its location helps indicate a system’s natural-frequency behavior, while its shape and magnitude provide evidence about frequency-dependent dynamics. Engineers examine these features to assess whether operating conditions may produce excessive vibration in a mechanical, electrical, or acoustic system.
Damping behavior influences how strongly and broadly a system responds near a resonance. Measurements collected across the sweep can therefore show whether the response is concentrated around a narrow region or distributed more broadly. Evaluating this behavior helps engineers characterize the system and determine how closely an analytical or computational model represents the observed dynamics.
Amplitude shows how strongly the system responds at each excitation frequency, whereas phase describes the timing relationship between the applied input and the measured response. Considering both measures gives a more complete picture of frequency-dependent dynamics than either measure alone. Together, they support resonance identification, damping assessment, and validation of engineering models.
Engineers first select a frequency range relevant to the system and then vary the applied excitation across that range. Instruments record response measures, including amplitude and phase, at the changing frequencies. The resulting measurements are examined for resonance peaks, damping behavior, and other frequency-dependent features, producing data for analysis of the system’s dynamic response.
The method is useful for vibration testing, modal analysis, structural health assessment, and characterization of mechanical, electrical, or acoustic systems. Its broader value lies in measuring how a system behaves over frequency rather than at only one operating point. This makes it suitable when engineers need evidence about resonances, damping, or changing dynamic response.
Sweep measurements can be compared with engineering models to support model validation and can reveal response features relevant to performance optimization. They also help identify conditions associated with excessive vibration or resonance-related failure. In this way, the results connect laboratory or field measurements with decisions about designed products, structures, and their dynamic behavior.
