Study involving X-ray imaging at Berkeley Lab provides clues to how artwork composed of oil paints can deteriorate over time
“We have used a tabletop, laser-based light source with pulses of X-rays at energies that have so far been limited only to large-facility sources," said researcher
At SLAC Synchrotron, two X-ray techniques give a 3-D view of why catalysts used in gasoline production go bad
To understand how molecules undergo light-driven chemical transformations, scientists need to be able to follow the atoms and electrons within the energized molecule as it rides on the energy "roller coaster"
Visible lasers offer exquisite control of x-ray light in a tabletop apparatus, potentially providing access to new insights to chemical reactions, proteins, and even atoms’ inner workings
Sulfur content is a key quality determinant for many petroleum products
In first study, Berkeley Lab scientists use the new station to examine hemoglobin
This application note describes how the Thermo Scientific™ Theta Probe was used to quantify the chemical composition and hydrogen concentration of an organic coating on a steel substrate.
X-ray photoelectron spectroscopy (XPS) is one of the most sensitive and informative surface analysis techniques available. However, XPS requires a high vacuum to operate, which makes analyzing materials in liquid and gaseous environments difficult.
