Description: Dynamic Mechanical Analysis (DMA) is an analytical technique used to evaluate the mechanical properties of materials as a function of temperature, time, frequency, or other external stimuli. It measures how a material responds mechanically under dynamic loading conditions, such as stress, strain, or deformation, while subject to varying temperature or frequency. Principle: DMA applies …
Description: The Coefficient of Thermal Expansion (CTE) refers to the fractional change in size or dimensions of a material per degree change in temperature. It quantifies how a material’s dimensions respond to changes in temperature, indicating the material’s expansion or contraction with temperature variations. Principle: CTE is determined by measuring the change in dimensions (length, …
Description: The BET (Brunauer-Emmett-Teller) method is a widely used technique for determining the surface area and porosity of solid materials, particularly porous materials, catalysts, and adsorbents. It’s utilized to measure the specific surface area by determining the adsorption of gas molecules onto a solid surface. Principle: The BET method is based on the physical adsorption …
Description: Atomic Emission Spectroscopy (AES) is an analytical technique used to identify and quantify elements based on the emission of light when excited atoms return to their ground state. Here’s an overview of its workings, applications, strengths, and limitations: Principle of Atomic Emission Spectroscopy (AES): Applications of Atomic Emission Spectroscopy: Strengths of Atomic Emission Spectroscopy: …
Description: Atomic Absorption Spectroscopy (AAS) is an analytical technique used to determine the concentration of various elements in a sample. Here’s an overview of its workings, applications, strengths, and limitations: Principle of Atomic Absorption Spectroscopy (AAS): Applications of Atomic Absorption Spectroscopy: Strengths of Atomic Absorption Spectroscopy: Limitations of Atomic Absorption Spectroscopy: In summary, AAS is …
