  Online workshop: Surface Ventures and DataPhysics Instruments offer workshop about Wetting of Hydrophilic Surfaces using Imaginary Contact Angles

  On 13 January 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 characterise hydrophilic surfaces. The workshop is designed for novices but also for experts in surface chemistry.

  Surface Ventures is a British non-profit organisation 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 characterise 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 characterisation 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 analyse 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, odour, 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 analyse and optimise long-term stability at different temperatures, an in-depth analysis is crucial during product development.

  This article has been published in the Euro Cosmetics magazine, Oct 2021, No. 29.

  Fair announcement: DataPhysics Instruments will be part of the ArabLab 2021 in Dubai

  The team of DataPhysics Instruments GmbH is happy to announce that they will be at the ArabLab 2021 in Dubai from 15 to 17 November 2021. You will find us in hall 4, booth 214, as part of the German Pavilion.

  DataPhysics Instruments GmbH, a German company with over 20 years of experience, specialises in measurement technology for surface science. We offer a wide range of devices which help analysing chemical and physical properties of surfaces and interfaces, including surface and interfacial tension, contact angle, surface energy, surface topography, and zeta potential as well as dispersion stability. Nils Langer, CEO of DataPhysics Instruments, will be present at the fair. He says: After the pandemic, the ArabLab will be our first fair appearance since 2019, which makes this date very special for me. The ArabLab is one of the most important trade fairs for laboratory equipment and we are looking forward to be a part of it.

  • Dynamic Contact Angle measuring devices and Tensiometer (DCAT series) are used to determine dynamic contact angles as well as surface and interfacial tension using standard probe bodies, such as the Du Noüy ring or the Wilhelmy plate.
  • Spinning Drop Tensiometers (SVT series) are optical instruments for measuring very low interfacial tensions and rheological properties. They offer possibilities for the analysis of surfactant efficiency, for example in the enhanced oil recovery.
  • Optical Contact Angle Meters (OCA series) are measuring devices which can determine contact angles of sessile drops down to picolitre-range. Using pendant drops, surface and interfacial tensions can be measured.
  • The MultiScan dispersion stability analysis system (MS) can conduct stability and aging analyses of dispersions, in particular suspensions and emulsions.
  • Our service portfolio includes contract measurements in our Application Centre for customers which do not have their own testing facilities.

  You will find us at the ArabLab 2021 from the 15 to the 17 November 2021 in hall 4, booth 214. We are looking forward to meeting you!

  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:

  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:
  24 June 2021
  10:00 or 16:00 CEST

  You can sign up for the webinar on the website of relyon plasma GmbH.

  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 measuring and contour analysis systems OCA 50 was used in the wettability studies that accompanied this work and warmly recommend you this great read.
