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.

This course is designed to meet the requests of many customers and expands and enriches the content of the previously popular course "Organic Structure Analysis" by including applied topics such as 2D-NMR analysis and chemical decomposition analysis. It is an ideal course for those who have taken the beginner course and want to deepen their understanding of organic structure analysis to aid in research and development.

We would like to inform you about the upcoming semiconductor fundamentals course hosted by Nisshinbo Micro Devices, which has received positive feedback and participation from many attendees each time. This time, we will be presenting "Introduction to Power IC Linear Regulators." The difficulty level is beginner, so we encourage everyone, from those who want to start learning about analog ICs to those facing challenges, to participate actively. With recorded lectures and live chat Q&A with our technical engineers, even busy engineers can learn efficiently. ● Target Participants - New employees and young designers - Those who want to refresh their knowledge of analog ICs - Those preparing for circuit design ● Agenda 1. What is a Power IC? 2. Linear Regulators - Shunt Regulators - Series Regulators 3. Key Characteristics 4. Main Functions 5. External Components 6. Thermal Characteristics We look forward to your participation.

In the world, there are more information systems than there are companies, but the number of systems that truly "help with a company's business operations" in a meaningful way is limited. To address this challenge, our company has developed and evolved our unique supply chain solutions, the "Φ-Conductor Series" and "Φ-Pilot Series." Since our establishment, we have upheld the philosophy of "together with our customers, for our customers," and, unlike many IT vendors, we have consistently focused on the effectiveness of our implementations, steadily building our track record. Therefore, on the occasion of our 25th anniversary, we have decided to hold an event where customers who have implemented our solutions will share their experiences regarding the effectiveness of the implementation and any challenges they faced. The companies presenting will include a diverse range of six user companies, primarily from the food industry. Additionally, at the concurrently held exhibition, we will showcase our original lineup, the "Φ-Pilot Series" and "Φ-Conductor Series," along with add-on features and optional products related to φ-Pilot that our partner companies are working on. We warmly invite you to attend this event.
