Strathclyde, UK, and UNIST and GIST (Korea) researchers use plasma gradient to force photons to “bunch up”. A new method of creating laser pulses, more than 1,000 times as powerful as those currently ...

Meselson, Stahl and Vinograd 1 first described the equilibrium density gradient technique for the examination of DNA in the analytical ultracentrifuge, and the technique has since been used to ...

Isolation of viable mononuclear and polymorphonuclear cells from blood serves as the starting point for a wide spectrum of immunology and cell biology studies. Unlike red blood cells and platelets, ...

Enrichment of leukocytes from blood products like buffy coat, leukocyte reduction chambers (LRSC) or leukapheresis material can be time consuming and could influence the physiology of the target cells ...

The Background Oriented Schlieren Method is a very simple technique to visualize density gradients, that base on the deviation of light rays due to refractive index changes. The technique can be ...

Osmotic energy, existing between the seawater and river water, is a renewable energy source, which can be directly converted ...

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in ...

As the global demand for clean and renewable energy continues to rise, harvesting low-grade energy sources such as salinity gradients has attracted ...
