June 25, 2020. Video “Process Lifetime Prediction with DSC and Kinetics Neo” (12 min) prepared by Dr. Thomas Haenel (NETZSCH sales manager) is published in the Applications. Video shows the software in action. In focus are: data import, model free fit, model based fit, process predictions and process optimization for the curing process of epoxide resin. It explaines what DSC data are necessary, how to create the kinetic model for the process having reaction steps of different directions: exothermal and exothermal. The video also demonstrates how to simulate the predictions for different temperature conditions or how to find the optimized temperature profile for the constant curing rate.
June, 08, 2020. New article "ICTAC Kinetics Committee recommendations for analysis of multi-step kinetics" is published (free download link). Basic principles and main recommendations from ICTAC for "isoconversional" (also known as "model free") methods and "multi-step model fitting" (also known as "model based") methods to be used worldwide are clearly described in this article. NETZSCH is the only commercial company producing commercial kinetics software, who took part in the development of these recommendations. One of the article authors Dr. Elena Moukhina in chapter 2 "Multi-step model-fitting" describes the theory, principles and methods of kinetic analysis implemented now in our Kinetics Neo software.

The kinetics, also called reaction kinetics or chemical kinetics, investigates the rates of chemical processes and allows for the determination of reaction rates. It also takes the factors that control these rates into consideration. Knowledge about points such as these can give deep insight into the detailed molecular mechanisms behind elementary reactions.
NETZSCH Kinetics Neo software is used to analyze chemical processes. The software allows for the analysis of temperature-dependent processes. The result of such analysis is a kinetics model or method correctly describing experimental data under different temperature conditions. Use of the model allows for predictions of a chemical system’s behavior under user-defined temperature conditions. Alternatively, such models can be used for process optimization.
The software can analyze different types of thermal curves that depict the changes in a given material property measured during a process. Potential data sources include studies using Differential Scanning Calorimetry (DSC), Thermogravimetry (TGA), Dilatometry (DIL), Dielectric Analysis (DEA) and Accelerating Rate Calorimetry (ARC).

Kinetics Neo follows the latest ICTAC recommendations published in the article "ICTAC Kinetics Committee recommendations for analysis of multi-step kinetics".
Model-Free Methods allow the activation energy of the reaction process to be found without the assumption of any kinetic model (ASTM E698, ASTM E2890, ASTM E1641, Friedman, Ozawa-Flynn-Wall, KAS, Numeric Optimization).
Model-Based Methods apply powerful cutting-edge mathematical calculations to create the best kinetic model; the different kinetic models can then also be compared statistically.
Predictions — Kinetics Neo is used for simulations and predictions once the experimental data has been described by either model-free or model-based kinetics. Predictions can be calculated for various temperature programs: isothermal, dynamic, multiple step, step-iso, modulated, or adiabatic.
Optimization is based on predictions; the temperature program can be optimized to achieve maximum product quality in the minimum amount of time.
Kinetics Neo runs under Microsoft Windows 10, Windows 8.x, or Windows 7 (either the 32-bit or the 64-bit version). Microsoft .NET Framework version 4.7 or later is required.
Minimum hardware requirements are: Intel i5 or similar CPU, 8 GB RAM. Faster processor (more MHz) and bigger RAM increase calculation speed.
