60 Years of NETZSCH-Gerätebau: Prediction of Material Behavior with Kinetics Neo

Coming close to the end of our company’s year-long 60th anniversary celebration, we’ll be sharing insights into the history of our software’s development in the month of December. Along with the preparation, execution and evaluation of thermoanalytical experiments, the prediction of the material behavior is also becoming increasingly important. This is where the NETZSCH Kinetics Neo software comes into play!

Prediction of Material Behavior and Reaction Processes

Materials with accurately defined properties can be transformed into other substances with other properties by chemical reactions. The reactions can take place within a fraction of a second – like in the case of explosions – or take hundreds of thousands of years, as is the case in the formation of minerals. This is because processes like Decomposition reactionA decomposition reaction is a thermally induced reaction of a chemical compound forming solid and/or gaseous products. decomposition, Curing (Crosslinking Reactions)Literally translated, the term “crosslinking“ means “cross networking”. In the chemical context, it is used for reactions in which molecules are linked together by introducing covalent bonds and forming three-dimensional networks.curing, CrystallizationCrystallization is the physical process of hardening during the formation and growth of crystals. During this process, heat of crystallization is released.crystallization and SinteringSintering is a production process for forming a mechanically strong body out of a ceramic or metallic powder. sintering of materials are dependent on time and temperature. Knowledge about the speed of these processes is therefore important in order to simulate material behavior or optimize a process.

Kinetics, also called reaction kinetics or chemical kinetics, studies the rate of chemical processes and allows for determination of reaction rates. It also takes the factors, which control these reactions, into account. And one of the most important factors is temperature. This knowledge can even save lives in the end, for example in the case of chemical industrial processes based on ExothermicA sample transition or a reaction is exothermic if heat is generated.exothermic reactions.

First Kinetics Version Already Available in the 80s

Dr. Johannes Opfermann worked at the University of Jena before joining NETZSCH in 1991. He developed the first version of the Thermokinetics software, which has been steadily improved over the decades and continues to be in further development today.

As with our Proteus®®® software, the first Kinetics software was a 16-bit version in the 90s.

Over the years, the software has undergone continuing development in parallel to the new modern computers, operating systems and processors on the market.

In 2002, Dr. Elena Moukhina joined the company – today her main responsibility is the Kinetics Neo Software Business Field. One of her first tasks was to translate the software from 16-bit into 32-bit –this was the birth of the second version of the Kinetics software, which was also available shortly afterward for Windows Vista and Windows 7 as version 3.

1-, 2-, 5- 10- or Even Higher-Level Reactions? Model the Most Complex Reactions!

A huge disadvantage at that time was usability of the software. The smallest of adjustments or implementation of new functions in the existing software involved tremendous effort. For customers, it was difficult to use Thermokinetics intuitively, without prior training. It was therefore decided in 2017 to completely rebuild the software from scratch.

Dr. Elena Moukhina and her colleagues at NETZSCH invested more than one year of development work and put the software on a new footing. Based on a modern Windows-based, intuitive user interface and new programming language, the limitation of models was eliminated. Since then, the software intelligently decides whether the reaction must be single-step, five-step, twenty-step or even other than that, and how the models must be linked together to best model the complex reactions.

The NETZSCH Kinetics Neo software comprises both model-free and model-based kinetic methods. With model-based methods, the number of reaction steps along with kinetic parameters can be determined for each individual reaction. This possibility is not offered by any other software!

Fig2 (right) Thermokinetics1, 2002: Switch-off of one of the curves in the diagram required a graphical dialog with many control boxes. 10 clicks were necessary to eliminate a measurement from the project.
TODAY: Fig3 Kinetics Neo, 2022: Display of an already-calculated model requires only one click by the user. One more click is enough to hide the curve in the graph, and another to eliminate the measurement from the project.

Analysis of Kinetic Processes by Means of Kinetics Neo – Here’s How It Works

Analyzing large chemical quantities in production processes can be dangerous. The NETZSCH Kinetics Neo software simulates temperature-dependent processes on the basis of small amounts. The result of such an analysis is a kinetic model or a method that correctly describes the experimental data under various temperature conditions. Use of this model allows for prediction of the behavior of a chemical system under user-defined temperature conditions. In addition, such models can be used to determine process optimization.

The software analyzes different types of thermoanalytical curves, representing the measured changes in a particular material property during a process. These methods comprise differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), dilatometry (DIL), dielectric analysis (DEA), accelerating rate calorimetry (Accelerating Rate Calorimetry (ARC®)The method describing isothermal and adiabatic test procedures used to detect thermally exothermic decomposition reactions.ARC®®), rheology and viscometry. Another feature setting NETZSCH Kinetics Neo apart is that it is readily available – without further preparation – for use with thermoanalytical instruments from a variety of manufacturers.

The first version of Kinetics Neo was exclusively developed for chemical reactions. Customers approached us asking for new application possibilities for the prediction of kinetic processes.

Further New Developments: Thermal Simulation 

Nowadays, our customers require an intelligent software solution with a variety of automated functions based on artificial intelligence. All this is currently being implemented into Kinetics Neo. The software enables existing and future customers not only to analyze and simulate laboratory processes easily and precisely, but also to predict high-scale, industrial processes.
