Scientists have achieved the ionization potential measurement of lawrencium (element 103) with a novel-type technique at the JAEA tandem accelerator. Based on the empirically developed "actinide ...
Researchers have for the first time measured the first ionization energy of lawrencium, the last of the actinides, validating predictions of the element’s electronic structure (Nature 2015, DOI: ...
Measurements of an artificial radioactive element called lawrencium could revive an arcane controversy over the element’s position in the periodic table — and the structure of the table itself. An ...

Discovering new inorganic materials is central to advancing technologies in catalysis, energy storage, semiconductors, and more. But finding a material with just the right properties is extremely ...
When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. A fundamental property of the rarest element on Earth, astatine, has been discovered for the ...
The covalent radius (a measure of how large individual atoms are) shows different trends if you are moving across a period or down a group. A comparison of the relative covalent radii of atoms is ...
One hundred fifty years after Russian chemist Dmitri Mendeleev published his system for neatly arranging the elements, the periodic table it gave birth to hangs in every chemistry classroom in the ...
Six critical steps are involved in the manufacturing of semiconductors. These steps include deposition, photoresist, lithography, etch, ionization and packaging. This article discusses several ...
