Online workshop: Surface Ventures and DataPhysics Instruments offer workshop about Wetting of Hydrophilic Surfaces using Imaginary Contact Angles
Wetting of Hydrophilic Surfaces using Imaginary Contact Angles
On January 13, 2022 at 13:00 GMT, Surface Ventures hosts a free, digital workshop on the topic of wettability of hydrophilic surfaces. DataPhysics Instruments sponsors the workshop and will demonstrate how to use a tensiometer to characterize hydrophilic surfaces. The workshop is designed for novices but also for experts in surface chemistry.
Surface Ventures is a British non-profit organization offering free online workshops about surface technology. Dr. Samuel McMaser, materials scientist from Coventry University, will host the workshop and speak about the fundamentals of surface chemistry, contact angle measurements and wetting analyses. Afterwards, Dr. Sebastian Schaubach, managing director of DataPhysics Instruments, will demonstrate how to measure contact angles on highly hydrophilic surfaces using the concept of imaginary contact angles with a tensiometer. Untreated and plasma-treated samples will be used as examples. The workshop is free and will be held in English. If you cannot join the live event, feel free to sign up anyway to gain access to the recording of the event.
Background information:The wettability of hydrophilic surfaces is excellent, which is why they are used in many fields, such as medical engineering or the paint and varnishing industry. Often, surface treatments such as UV-light and plasma are used to achieve higher wettability. However, conventional measuring methods often struggle to characterize hydrophilic surfaces properly, as liquid will spread quickly and fully on the surface. The concept of imaginary contact angles, which will be explained in the workshop, makes the characterization of such hydrophilic surfaces possible.

Press article: How long does beauty last?
Cosmetic products, often consisting of multiple components and phases, should stay stable and uniformly mixed over long periods of time. The MultiScan MS 20 system developed by the German laboratory equipment manufacturer DataPhysics Instruments can analyze how the stability of a multi-phase liquid changes over time and at different temperatures. Researchers in the cosmetic industry can therefore ensure high product quality and longevity from the get-go. Cosmetic products, such as creams, emulsions, lotions, or cleansers, consist of multiple ingredients and are usually multi-phase mixtures. Their formulations are elaborately composed and refined to meet numerous requirements regarding function, appearance, texture, odor, and stability. It must be ensured, for example, that the product is still homogeneous when applied at body temperature, when stored at room temperature for several months or when forgotten in the car on a hot summer day. To analyze and optimize long-term stability at different temperatures, an in-depth analysis is crucial during product development.

Talk announcement: Investigation of plasma effects on implants
Our managing director Dr. Sebastian Schaubach will give a talk on the Investigation of plasma effects on implants as part of the webinar series plasma in the medical sector of the relyon plasma GmbH:
plasma in the medical sector
To characterize the surface chemical properties of a material, contact angle measurements and calculated surface free energies have proven to be reliable parameters over many years. For example, the effect of plasma treatment on a wide variety of surfaces can be quantified. But what do you do if the surface to be characterized is very finely structured or exceeds the measurement capabilities of classical optical contact angle measurement? In our webinar we would like to show you how special picoliter dispensing systems can be used to measure the contact angle on plasma-needled dental implants with a very fine structure. Furthermore, we will show you the concept of imaginary contact angles with which hyperhydrophilic surfaces can also be quantitatively investigated with regard to wettability.
Dates:June 24, 202104:00 EDT (08:00 UTC) or 10:00 EDT (14:00 UTC)
You can sign up for the webinar on the website of relyon plasma GmbH.

The new Zeta Potential Analyzer ZPA 20
The Zeta Potential Analyzer ZPA 20 is a compact measuring instruments that utilizes the patented bidirectional oscillating streaming potential method. It is designed to measure the zeta potential of various macroscopic solid samples with highest accuracy and within shortest time. With its powerful stepping motor and innovative method, the ZPA 20 can measure zeta potential values in less than a minute and with high statistical quality.
The modular setup of the ZPA 20 allows for easy exchange of the measuring cells. Hence, the zeta potential of plate shaped solids, fibers, powders and granulate material can be measured. Using a liquid dosing unit LDU 25 the composition of the electrolyte can be changed and for example the isoelectric point or the adsorption kinetic of a surfactant can be determined.
Live online streaming setup
With our live online streaming setup, we are able to do live webinars, product demonstrations and much more. Since on-site visits are still restricted in many cases, we even did some first-time device installations and instructions for new customers with our online streaming setup.
During an online session we can switch between multiple cameras and the presenters PC in order to show you our measuring devices, software or talk slides in great detail. Highest image and sound quality are ensured by the professional video equipment and dedicated microphones for each speaker. Hence, we can even record the session in up to UHD quality and provide them as a download to the participants afterwards.
For our live sessions and webinars, we primarily use Microsoft Teams, but since some companies have strict rules as to which software they can use, we designed our setup to be independent of the used transmission or conferencing software. Hence, we can flexibly adapt to the software preferred by your company as long as it supports screen sharing.
Please contact our applications center or your local distributor for an individual device demonstration or application training. Stay tuned for more upcoming live webinars or consider visiting one of our existing webinars.

Design of robust superhydrophobic surfaces
The properties of superhydrophobic surfaces are highly desirable in many industries and applications. Unfortunately these surfaces often suffer from low durability. They are for example easily scratched by hard objects and their superhydrophobicity is destroyed.
In the latest Nature cover story Wang, D., Sun, Q., Hokkanen, M.J., Ras, R.H.A. et al. introduce a new strategy to create superhydrophobic surfaces that have a high mechanical stability. They designed a material matrix that combines the superhydrophobic nanostructure with a highly durable macrostructure. This new material can be even scratched with a razorblade or with sandpaper without losing its superhydrophobic properties. Due to its transparent nature the new material matrix is an ideal candidate for a new kind of self-cleaning cover material for solar panels.
We are proud that one of our optical contact angle goniometers and drop shape analysis systems OCA 50 was used in the wettability studies that accompanied this work and warmly recommend you this great read.

The new Spinning drop Video Tensiometer SVT 25
The SVT 25 is the new Spinning drop Video Tensiometer of the SVT series. With completely redesigned electrical components and many improvements it will continue the legacy of its successful predecessor SVT 20N.
Due to the high-performance camera with USB 3 interface the SVT 25 can resolve spinning drops with up to 2048 x 1088 pixel and hence offers five times the resolution of its predecessor. In Addition fast processes e.g. during oscillation experiments can be captured with up to 3250 frames/s.
The TP 50 control panel with touch screen and precision control wheel ensures a fast and intuitive device control, even during complex measurements. It enables an easy and precise control of the rotational velocity, tilting angle, camera position, illumination and the temperature of the new measuring cells.
Introducing the new Surface Profile Analyzer SPA 25
The new Surface Profile Analyzer SPA 25 can measure surface topography and roughness parameters with exceptional speed and resolution. Due to the utilization of the white-light interferometry measuring technique the Surface Profile Analyzer can reach a height resolution of 0.1 nm.
Using the industry leading MountainsMap® Imaging Topography software the SPA 25 enables an incredibly detailed 3D visualization of surface texture. Furthermore the surface roughness can be analyzed according to various industry standards like ISO 25178, ISO 4287, ISO 13565, ISO 16610, etc.
Using the SPA 25 in combination with an optical contact angle goniometer and drop shape analysis system of the OCA series provides further insight into surface properties by e.g. determining the surface corrected contact angle according to the Wenzel theory.
Topview contact angle measurement – now even on smallest surface areas
With the picoliter dosing system PDDS and a new, special topview measuring system from DataPhysics Instruments it is now for the first time possible to measure contact angles in topview automatically even on smallest surface areas, using the optical contact angle goniometers of the OCA series. Hence, wettability and surface energies of, for example, individual paths and contacts of printed circuit boards can be studied – even when the side view needed for conventional contact angle measurement is obstructed.
Make an appointment now with our Applications Center and experience first-hand how your very own surface chemistry questions are answered. No matter how small and demanding your samples – we from DataPhysics Instruments accept the challenge and will tailor you an optimal solution.
