High Performance Liquid Chromatography is a separation technique employed by analytical chemists for the separation, identification, and qualification of multiple compounds in a solution. The majority ...

(Phys.org)—Many biological systems involve dense packing of a large amount of material or particles in a confined space. For example, eukaryotes' nuclei hold about two meters of DNA that is tightly ...

From avalanches to pharmaceuticals, the physics of powders relies on a much-maligned talent. The alternative text for this image may have been generated using AI. For a cognitive skill that plays such ...

Aim: Sampling, sample preparation, and off-line measurement are inconvenient steps for particle size characterization, as they require trained operators, method validation and sometimes transport to ...

A packing is defined as a large collection of nonoverlapping solid objects in d-dimensional Euclidean space . A simple but important attribute of a packing is its packing density ϕ, defined as the ...
