A solid sample material has to always be sufficiently prepared by homogenization and size reduction before exposure to physical or chemical analysis. Care should be taken that the analysis sample ...

In general, a sample is a limited quantity of something which is intended to be similar to and represent a larger amount of that thing(s). The things could be countable objects such as individual ...

Materials scientists can learn a lot about a sample material by shooting lasers at it. With nonlinear optical microscopy—a specialized imaging technique that looks for a change in the color of intense ...

To produce high-quality cement, the mineralogical and chemical composition of raw materials, as well as of intermediate and finished products, needs to be determined. At each stage of the production ...

Sequencing-based studies of the human faecal microbiota are increasingly common. Appropriate storage of sample material is essential to avoid the introduction of post-collection bias in microbial ...

In materials science, 2-D is the new 3-D. A vacuum chamber for using X-ray spectroscopy to measure sample materials, the tiny squares of various colors, on a copper sample holder, at Berkeley National ...
