ADVANCE software now with touch operation

ADVANCE software now with touch operation

We will present our ADVANCE software for interfacial analysis, which is designed for touch operation, at the upcoming analytica trade fair in Munich, Germany. With this new development within the software, we improve the mobility of our measuring technique for tasks such as on-site testing of pretreated or cleaned surfaces. Touch displays are also gaining ground in the lab environment, as they save on space and are easy to clean.

Benefit from our continuing developments with the ADVANCE Software Assurance

The time for acquiring anything high-tech never seems to be right: One doesn‘t want to miss the next innovation step which is always imminent. ADVANCE, our universal software for interfacial analysis, is no exception to this rule. With at least one and usually two releases annually, we continuously extend the range of functionality with new powerful features. Thanks to regular upgrades within the framework of the ADVANCE Software Assurance, you will never miss a new development and will always work with the latest version.

Application
Dosing falling drops with a defined volume for contact and roll-off angles
Dosing falling drops with a defined volume for contact and roll-off angles

When it comes to measurements involving falling drops, the drop size and fall height have to be kept constant if comparable results are to be achieved. If the same needle diameter is used, falling drops of the same liquid are indeed always the same size. However, it is almost impossible to specify the volume or to dose different liquids with the same volume. We present a solution to this problem and show you how to generate drops with an exact, defined volume and purposefully detach them from the needle.

Force Tensiometer – K100: First-class instrument for interfacial analysis

Our universal Force Tensiometer – K100 performs high-precision, automatic measurements of surface and interfacial tension, critical micelle concentration (CMC) and contact angle on solids, fibers and powders. With high-quality components, diverse accessories and a uniquely wide range of methods, the instrument carries out many tasks in the field of surfactant analysis as well as wetting measurement for your quality assurance or research.

Beyond the surface
From the “tears” in a wine glass to the micromotor

From the “tears” in a wine glass to the micromotor

Droplets in a wine glass, which flow upwards against gravity, are the best-known result of the “Marangoni effect”. This flow movement is caused by the alcohol evaporating at the boundary layer, creating a surface tension gradient. A working group at East China Normal University in Shanghai used this effect to purposefully move small objects across water or make them rotate. Minibots could potentially be driven in this way without generating any airborne emissions. The researchers even managed to convert the kinetic energy of a moving drop into electrical energy.

Snowflakes made of liquid metal

The gallium/indium metal alloy is a liquid and has the highest surface tension of all known substances at room temperature. Something fascinating happens when an electric field is applied to this conductive liquid. The alloy starts to flow and forms snowflake-like fractals (video) – which are visually appealing and mathematically interesting structures consisting of self-repeating patterns in different sizes. According to researchers at North Carolina State University, USA, the effect is caused by electrically induced oxidation, which changes the surface tension locally. The researchers assume that the phenomenon can be used to control both surface tension and flow in a targeted manner.
