The stability and lifetime of lithium-ion batteries hinges on deciphering the reactive processes that occur where the cathode meets the electrolyte. During cycling, electrolyte components oxidise at the cathode-electrolyte interface and form a thin, reactive interphase. This layer is commonly known as the solid electrolyte interphase (SEI), or more specifically as the cathode-electrolyte ...
The measurement of manufactured components has evolved across decades. Traditional coordinate measuring machines (CMM) set a foundation for precision validation, while optical metrology introduced speed and non-contact ...
The chemistry of a material’s outermost nanometres often determines its functional performance, making accurate surface characterisation vital for modern materials research. Yet, analysing these nanometre-scale layers is inherently challenging, as many surface-sensitive chemistry techniques, like AES, can modify the material or disturb its native chemical composition and techniques like EDX ...
Why do some of the most promising next-generation batteries fail—and how can we stop it? A new peer-reviewed study led by Imperial College London answers that by watching the failure process unfold as the battery operates. Using simultaneous dual-polarity secondary-ion mass spectrometry (SIMS) alongside controlled electrochemical cycling, the team directly observed where, when, and why ...
They constitute an intricate "glycocode" that orchestrates numerous cellular functions from embryonic development to immune regulation and disease progression. N-Glycan Profiling: Beyond the Basics N-Glycan Profiling reveals the remarkable complexity of these structures that anchor to asparagine residues. ...
Nanotechnology operates at a scale where a few atoms can change everything. Whether developing next-generation semiconductors, targeted drug delivery systems, or catalytic surfaces, precision is paramount. But how do you ensure consistency, safety, and performance at the ...
A lot can be learned about compounds and molecules by assessing their molecular masses and the make-up of their structures. This knowledge can provide an understanding of a compound’s characteristics, such as its solubility and reactivity, and help enforce quality control, for instance in pharmaceutics, by identifying contaminants and impurities. A technique used to quantify the ...
Quadrupole mass spectrometry is a fundamental technique in the field of mass spectroscopy, originating from the pioneering work of Wolfgang Paul and Helmut Steinwedel in the 1950s. Today, quadrupole MS is renowned for its rapid scanning capabilities, high sensitivity, and ability to provide quantitative and qualitative analyses. It uses electric and magnetic fields within a mass analyzer to ...
Surface contamination analysis is crucial in engineering and materials science industries as it helps researchers study a material’s surface layer composition. Using secondary ion mass spectrometry (SIMS), the composition of a surface layer can be identified and characterized and this information is then used to investigate contamination, defects, and trace elements on a substrate’s ...
The imaging powers of chemical microscopy have helped to uncover the smallest worlds that we previously never could see. Uncovering different aspects of particles, such as their shapes and sizes, is only one of its uses. In fact, chemical microscopy can be used in biology to learn about proteins and how DNA reacts to drugs. It can also analyze the most minute formations within various types of ...
What is Wafer Metrology? Wafer metrology refers to the precise measurement and analysis of semiconductor wafers used in the manufacturing of integrated circuits (ICs) and other electronic devices. It involves assessing various characteristics of wafers, such as dimensions, surface morphology, and material properties, using specialized techniques and ...
Our goal is to provide you with the tools to make the right decision when it comes to selecting the right soil sensor for your application. We are delving into the most asked question. How do soil moisture sensors work, and what is the difference between a point and profile measurement? Soil moisture sensors measure the water content in the soil and can be used to estimate the amount of stored ...

The pinhole is essential for this, as without it the out of focus Raman scatter would also be detected resulting in a blurry image with poor axial resolution; the pinhole increases the image contrast and improves the axial resolution.The microscope stage can also be scanned along the Z- axis to change the depth of the focal plane within the sample. The variation in the Raman ...
