Specific heat capacity Cp can be simply defined as the amount of heat required to raise the temperature of a mass unit of material by 1 K at constant temperature and pressure. The determination of this thermophysical property of a material is essential in a large range of application fields, more particularly when the considered material has to be cooled or heated, whether it is during its synthesis, treatment, use, or recycling.
Thermal Analysis and Calorimetry provide solutions for the research and thermal characterization of nuclear materials, and for the quantification of radioactive elements throughout the civil nuclear energy sector: extraction of uranium ore, conversion and enrichment of uranium, manufacture of fuel, design of reactors, recycling of spent fuel, treatment of waste, etc. The webinar will focus more on the characterization of the fuel (thermophysical properties, preparation, reactivity) and wastes (data to characterize their transport in the environment, their treatment processes, and their heat production).
Thermal Energy Storage (TES) is defined as the temporary storage of thermal energy at high or low temperatures. As most of the renewable energy sources (solar, wind, …) are intermittently available, the target of TES is to improve performances of energy systems with a smoother supply and an increased reliability. The three main types of thermal energy storage use sensible heat, latent heat or thermochemical heat. For each TES mode, various types of transitions or reactions are exploited.
The webinar will focus on how the thermal analysis and calorimetric methods can be used to investigate the different TES techniques and to characterize the transitions or reactions of typically used materials (fatty acids, paraffins, organic substances, inorganic salts, adsorbents, clathrates).
Titration TGA is a new concept based on the injection of calibrated gas or vapor doses on a sample whose mass is measured by a thermobalance. The presentation will demonstrate how the method can be applied to the calibration of TGA-EGA systems, leading to quantitative analyses of the evolved gases even in gas blends. It will also focus on how – together with the new SETSYS Vapor Sorption instrument – Titration TGA allows for the characterization of gas and vapor sorption.
The presentation will aim at showing how thermal analysis and calorimetry can be used to study the properties of batteries and of battery elements.
It will review examples of batteries materials characterization, energetics of charge/discharge, batteries safety and thermodynamics of bulk and nano battery elements.
LABSYS evo is a comprehensive line of thermal analyzers (TGA, STA or DTA/DSC) with two available temperature ranges, from room temperature up to 1150°C or to 1600°C. The presentation will detail more particularly the applications of:
- LABSYS evo TGA 1150 : compositional analysis, moisture or solvent content, thermal ageing of organic materials like polymers, pharmaceuticals or petroleum by-products
- LABSYS evo STA 1600 : study of the thermal behavior of materials that are exposed to extreme temperatures during their production, service, or recycling including inorganic materials like ceramics or metal
Some steel based alloys, when quenched after being overheated, form a given quantity of residual or retained austenite. Being able to control the martensite/austenite ratio of the steel means controlling the quality of the material. Sigmametry is a measurement technique for QC of materials from production. It is based the ferromagnetic properties of martensite. It is commonly used by companies worldwide, as it is a very simple and quick method. We will review and compare different retained austenite measurement methods using sigmametry.
Failure analysis, process validation and competitive investigations often require a sample to be deformulated to identify components and to understand processing differences. TGA-IR provides tools for just this purpose. This webinar will describe the TGA-IR experiment and then focus on the infrared data analysis, using manual and highly automated tools, including the patented Thermo Scientific™ OMNIC™ Mercury TGA software.
The experimental studies of frameworks have been focused on many classes of materials: metals, zeolites, metal-organic frameworks (MOFs), nano oxides, etc. Understanding their sorption properties, thermodynamic stability and the energetics of gas-solid interactions is essential for their applications.
Differential Scanning Calorimetry is the ideal thermal stability screening, small-scale (mg) tool for laboratories involved in process safety and thermal hazards investigations. The flexibility of such a technique allows the investigations with different experimental conditions to predict the various situations that can occur during a decomposition and to simulate the different parameters that can affect such phenomena.
Nanomaterials have become extremely important in applications as catalysts, batteries, and sensors because of the high surface-to-volume ratio, which makes them more reactive than the macroscopic analogues.
The application of coupled techniques in the field of thermogravimetric analysis is well established, particularly for the investigation of the chemistry of thermal decompositions and identification of the evolved species
This webinar will compare the two techniques in offering a better understanding of their core capabilities and limitations.
