X-Ray photoelectron spectroscopy (XPS) is one of the most important and widely used methods for determining surface chemistry of materials. Cryo-XPS, where the sample is cooled to temperatures below ...

NASA has finally shared details about the first analysis of samples taken from the asteroid Bennu using the OSIRIS-REx spacecraft in 2020. While NASA scientists are still working on documenting the ...

Early analysis of the asteroid Bennu sample returned by NASA's OSIRIS-REx mission has revealed dust rich in carbon, nitrogen, and organic compounds, all of which are essential components for life as ...

Four principal methods govern the preparation of samples for XRF analysis, each representing a different trade-off between analytical quality and speed/cost of preparation. A method involving the ...

Mass spec–based methods coupled with chromatography separation techniques are fundamental to success in proteomics research and biopharmaceutical development, and low-flow liquid chromatography has ...

A sample from the asteroid Bennu, collected by the OSIRIS-REx mission, has arrived at London's Natural History Museum for analysis. Scientists are optimistic that it could contain the seeds of life.

Scientists are working hard to analyze samples of the potentially hazardous asteroid Bennu, with early results suggesting it may even be a chunk of an ancient water world. When you purchase through ...

Agricultural soil testing is critical to determining soil’s nutrient concentration and variability across your fields. It is ideal to test your fields’ soil at least every two to three years to inform ...
