Laboratory chamber walls have been stealing vapors, causing researchers to underestimate the formation of secondary organic aerosol in the atmosphere. A study published April 7 in PNAS Online Early ...

Keeping high-power particle accelerators at peak performance requires advanced and precise control systems. For example, the primary research machine at the U.S. Department of Energy's Thomas ...

A 115-year effort to bridge the particle and fluid descriptions of nature has led mathematicians to an unexpected answer. In 1900, the great mathematician David Hilbert presented a list of 23 unsolved ...

What is Particle Size Distribution Analysis? To determine the size and range of particles in a specific material, particle size distribution (PSD) analysis is used. Several techniques are used to ...

Physicists have found that an elementary particle called the W boson appears to be 0.1% too heavy — a tiny discrepancy that could foreshadow a huge shift in fundamental physics. The measurement, ...

Proteins consisting of amino acids are key macromolecules that play essential roles in all kinds of activities in living organisms. In particular, amino acids are bound by peptide bonds to create ...
