Mechanisms of bubble generation, stability, and collapse, and the optimal formulation of defoamers.

The "forces" of liquids: Various interfacial phenomena such as cleaning, wetting, penetration, foaming, and defoaming are due to the effects of the surface and interfacial tension of liquids.

Liquids are in a state where molecules can move relatively freely. Focusing on the molecules present at the surface (more precisely, the "interface" between the liquid and the atmosphere), intermolecular forces act not only between the molecules on the bulk side but also between the molecules in the atmosphere. However, due to the overwhelmingly high density of the molecules on the bulk side, the molecules present at the surface are constantly being pulled inward (toward the bulk side). As a result, it appears that a tension is acting to contract the surface. This is known as "surface tension" (more precisely, interfacial tension). Our company offers contract measurements for contact angle, surface and interfacial tension, friction and wear analysis, adhesion and film peeling analysis, zeta potential, anti-fogging evaluation, and more.

An automatic dynamic surface tension meter equipped with a built-in thermostat and thermometer, designed for ease of use.

The automatic dynamic tensiometer BP-D5 is a system that continuously measures dynamic surface tension from the moment the interface is formed by adopting the maximum bubble pressure method. Various controls and measurements are performed using the FAMAS software, which is also well-regarded for contact angle measurements in cooperative interfacial science. 【Features】 ○ Continuous measurement while varying the lifetime (20 to 5,000 ms) → Measurement up to 15,000 ms is possible as an option ○ Dynamic surface tension measurement at a constant lifetime is possible ○ Real-time display function of bubble pressure waveforms and LED strobe lighting function allow for monitoring the state of the bubbles ○ A series of operations from adjusting the probe depth to starting the measurement can be performed with the push of a button ○ During surface tension measurement, the temperature (°C) of the liquid sample can be recorded, allowing for temperature correction of surface tension for liquid samples with known temperature coefficients For more details, please contact us or refer to the catalog.

A New Evaluation Method for the Persistence of Liquid Films (Foam Films) Using a Surface Tension Meter: Possibilities for Application in Coating Film Quality Assessment.

A new evaluation method for liquid membranes as an alternative to lamella length measurement has been devised! - Available as an option for the DyneMaster series of surface tension meters. - This evaluation method serves as an effective means for cases where clear differences exist in sensory evaluations, but differences are not easily visible in surface tension or lamella length measurements, making quantitative assessment difficult. - For other features and details, please download the catalog or contact us. *For more information, please refer to the PDF materials or feel free to contact us.

Creating 3D Plots Using Igor Pro ~3D Scatter Plots and Surface Plots~ This document introduces how to create a 3D scatter plot from a point cloud data given in XYZ coordinates using Igor Pro, as well as how to create a surface plot using the same data. 1. Overview of 3D Plots 2. Operation Demo: Creating a Scatter Plot 3. Operation Demo: Creating a Surface Plot

To address questions such as "I have never talked to a small and medium-sized enterprise consultant," "I don't know what they can do for me," and "I would like to have a simple consultation about management issues first," we have started offering a "Simple Management Diagnosis Service" that can be used for free for the first time. It is scheduled to be conducted via "WEB conference" for about one hour. Please feel free to use this service (we also accept on-site consultations, subject to travel expenses).

In addition to the lecture by Mr. Eddy Dascotee from DDS, it has been decided that Professor Okubo, an emeritus professor at Chuo University, will also speak. Professor Okubo is globally recognized in the field of precision mechanical engineering, particularly in "vibration and mode analysis," and has made significant contributions to the noise reduction and high performance of automobiles and machinery. He received the "Order of the Rising Sun, Gold and Silver Rays" last year. He will talk for about 20 minutes about his activities and introduce the seminar. This is a rare opportunity to hear the "real insights" from Mr. Dascotee, who is at the forefront of the industry, and Professor Okubo, who has been active in the field for many years. We encourage everyone to come to the venue on May 21 (Thursday). (Application deadline has been changed to May 21, the day of the event.) "Does your CAE align with reality?" How can experimental data (MEscope) be accurately fed back into the analysis model (FEMtools) to connect the cycle of design, experimentation, and analysis? The latest world-standard methods will be elucidated by the developers themselves.
