Berkeley Lab researchers have detected the smallest force ever measured – approximately 42 yoctonewtons – using a unique optical trapping system that provides ultracold atoms. A yoctonewton is one septillionth of a newton.
Berkeley Lab researchers have developed a new technique called two-dimensional electronic-vibrational spectroscopy that can be used to study the interplay between electrons and atomic nuclei during a photochemical reaction. Photochemical reactions are critical to a wide range of natural and technological phenomena, including photosynthesis, vision, nanomaterials and solar energy.
It’s now more or less official: element 117 will have a seat at the periodic table. Earlier this month an international team of scientists that included researchers from Lawrence Berkeley National Lab’s Nuclear Science Division found two atoms of superheavy element 117. The experiment, conducted at a particle accelerator at the GSI Helmholtz Center for
Probing dopant distribution: Finding by Berkeley Lab Researchers at the Molecular Foundry Opens the Door to Better Doping of Semiconductor Nanocrystals
Berkeley Lab researchers at the Molecular Foundry have shown that when doping a semiconductor to alter its electrical properties, equally important as the amount of dopant is how the dopant is distributed on the surface and throughout the material.
Berkeley Lab researchers have demonstrated a technique that for the first time allows the catalytic reactivity inside a microreactor to be mapped in high resolution from start-to-finish. This technique opens a more effective and efficient synthesis of pharmaceutical drugs and other flow reactor chemical products.
Through a combination of water, oil and nanoparticle surfactants plus an external field, spherical droplets are being transformed into ellipsoids and other unusual shapes that could find many valuable uses.
Berkeley Lab researchers have shown that, contrary to the scientific axiom that only opposite charges attract, when hydrated in water, positively charged ions can pair up with one another.
At the Advanced Light Source, scientists analyzed samples from a Roman breakwater that has been submerged in the Bay of Naples for over two millennia, revealing the secrets of crystal chemistry that allow Roman seawater concrete to resist chemical attack and wave action for centuries. The manufacture of extraordinarily durable Roman maritime concrete released much less carbon than most modern concrete does today and presents important opportunities for improving quality and reducing atmospheric carbon.
Berkeley Lab scientists have produced remarkable images of carbon atoms and the bonds among them. Resembling glowing textbook diagrams, hydrocarbon molecules are shown in high resolution for the first time before and after the breaking, rearrangement of atoms, and reforming of bonds during a complex chemical reaction.
