Secondary Ion Mass Spectrometry (SIMS) is a surface analysis technique known for high sensitivity and excellent depth resolution in the analysis of solid materials. ...
Lake ecosystem water quality fails follow a predictable sequence of physical and biological processes that begin weeks before a surface bloom is visible. The analysis here is oriented toward water quality managers, utilities, and lake operators, and focuses on monitoring, thresholds, and intervention strategies that can be deployed before operations are affected. ...
In conventional residual gas analysis, species with similar masses may overlap and appear as a single peak. ...
As temperature changes, molecules bound to a surface respond in ways that reflect how and where they are attached. Temperature programmed desorption uses controlled heating to trigger such responses in a systematic way. When evolved gas analysis is applied at the same time, desorbing species can be identified when they appear, allowing surface ...
Nuclear fusion research is rapidly scaling from core science to reactor-relevant engineering, driven by major public funding and accelerating private investment. As tokamak, stellarator, and inertial confinement programmes move toward longer pulses and integrated fuel-cycle operation, the diagnostic demands are rising fast. In simple terms, fusion teams need nuclear fusion gas analysis that is ...
Although the SEI is crucial for stabilising the cathode-electrolyte interface, it is only a few nanometres thick and chemically varied, which complicates its analysis with conventional analytical techniques like X-ray Photoelectron Spectroscopy (XPS) or Raman spectroscopy. Secondary Ion Mass Spectrometry (SIMS) surface analysis is a powerful ...
Traditional X-ray Photoelectron Spectroscopy (XPS) is a cornerstone technique for investigating the surface chemistry of materials. However, conventional XPS systems operate under ultra-high vacuum (UHV) conditions — a controlled environment necessary for accurate measurements, but far removed from the pressures and reactive conditions most materials experience in real-world ...
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 ...
Introduction Surface finish tells us a lot about how a part will perform, whether it will seal properly, move smoothly, or wear too soon. Measuring surface roughness is the science of quantifying those tiny peaks and valleys on a material’s surface. Over the years, this field has evolved from contact-based tools to advanced non-contact optical metrology techniques that deliver microscopic ...

A profilometer is a precision instrument used to measure the surface profile of objects, providing critical insights into surface roughness, texture, and step height. For anyone working in industries requiring high accuracy, understanding profilometers is essential. This guide explains everything about profilometers, from basic principles to industrial applications. ...
Advanced semiconductor manufacturing necessitates control at every stage of the fabrication process, with etch processes being among the most critical to perform with precision. Even a microscopic deviation at a material interface can impact device performance, yield, and long-term reliability. Secondary Ion Mass Spectrometry (SIMS)-based end point detection has emerged as a dependable way to ...
Why composition control matters Tool steel is the foundation of cutting and measuring instruments, machine parts subject to heavy wear, and dies for cold and hot forming. Even the slightest deviations in its composition can affect hardness, wear resistance, or hardenability. The result: equipment downtime, costly remelting of batches, or reduced service life of finished products. For ...
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 ...
