The growing of semiconductor materials industrialization requires technologies to characterize their properties. Optical microspectroscopic platforms like Raman microscopes offer both physical and chemical information in one system. Thus, process qualification, wafer uniformity assessment, or defects inspection of wafers can be achieved with Raman microscopy. These can also be applied to new materials characterization.

In this webinar, we will highlight how Photoluminescence and Raman microscopies can address semiconductor challenges. We will also show how the combination of micro-spectroscopies with AFM (Atomic Force Microscopy) can provide nano resolution and deeper understanding of these structures.

Carbon materials are crucial due to their widespread application in industries like energy storage. Analyzing carbon helps ensure material quality and performance. However, its structural complexity and variability, such as the presence of defects and morphological disparities, pose challenges, making precise analysis difficult.

Standard spontaneous Raman scattering effect is limited by its sensitivity. Different strategies are set in place to improve the sensitivity and the mapping speed based on different physical phenomena. These approaches resulted in the development of Stimulated Raman Spectroscopy (SRS), Coherent Anti-Stokes Raman Spectroscopy (CARS), Resonant Raman spectroscopy, etc., each of which have advantages and limitations.

During this webinar, we will present the concept of these different techniques, and discuss their benefits and concerns.

Microplastics are becoming the 21st century environmental scourge. To control it, more and more regulations are being set in all countries worldwide to monitor the amount of microparticles released in the environment. Thus, some techniques have been identified as reference methods: Pyrolysis GC-MS, Infrared microscopy, and Raman microscopy. This last one provides the best combination of information in both morphological and chemical characterization of each particle down to the micron.
During this webinar, we will present how Raman microscopy is becoming the best reference method for microplastics characterization.

With the global energetic transition and the move from thermic to electric cars, the improvement of battery becomes crucial. With that development, the analytical techniques used must be also adapted and developed to understand the physical and chemical processes occurring at the electrodes and electrolyte levels. Thus, Raman microscopy is an ideal method as it provides physical and chemical properties of materials in a non-invasive approach.

During this webinar, we will present how Raman microscopy can be applied for battery characterization, and for fuel cells, the future of batteries.

Raman microscopy is the combination of the Raman effect and optical microscopy. A Raman microscope is the association of multiple components where each of them is playing a specific role to achieve highly resolved and sensitive measurements.
During this webinar, we will present the role of each component of a Raman microscope and detail their characteristics and limits.

Particulate matter poses a growing threat to air quality and public health. To effectively understand the effects and assess the hazardousness of particles, it is necessary to study them on a molecular level. Raman spectroscopy emerges as an effective method for revealing the chemical composition of airborne particles at the microscopic scale.

Disinfecting your hands with hydroalcoholic gel has become a daily practice. In the meanwhile, 70° alcohol has been used for even longer to disinfect wounds. But, to remain efficient, the alcohol concentration of these products must not be below a defined threshold and must be controlled. This application note demonstrates how to evaluate alcohol concentrations in a quality control process with Raman.
