solid phase epitaxial growth/ atomic structurecobalt silicide islandsreactive epitaxySTMWe report STM observations of the reaction of cobalt deposited on Si(111) at 320°C. At low coverage, coherent monolayer silicide islands form in a matrix of 7 × 7 reconstructed silicon. The islands take one...
Q1. The isotope cobalt-60 (60Co) is used to destroy cancer cells in the human body.Which statements about an atom of cobalt-60 are correct?1. It contains 33 neutrons.2. Its nucleus has a relative charge of 27+.3. It has a different number of neutrons from the atoms of other ...
Engineering the surface structure at the atomic level can be used to precisely and effectively manipulate the reactivity and durability of catalysts. Here we report tuning of the atomic structure of one-dimensional single-crystal cobalt (II) oxide (CoO) nanorods by creating oxygen vacancies on pyram...
When superscripts are not used, a more literal form of designation, such as cobalt 60, is commonly used. Referring to the helium atom, one simply writes 4 He, where 4 is equal to the atomic weight (because of the aggregation of protons and neutrons in the nucleus). Show moreView ...
Growth process for sulfur-hosted atomic cobalt-decorated hollow carbon composite The synthetic process of the S@Con-HC is illustrated in Fig.1. The successful encapsulation of Co nanoparticles (NPs, ~3 nm) and S is attributed to the microporous and hollow structure of carbon spheres. Initially...
The research focused on observations of a cobalt-chromium-nickel high entropyalloy, revealing how differentheat treatments can change SRO. “This provides a template for future studies in which SRO controls critical material properties. There is lots more to do on various aspects of the analysis of...

So, when we observe that people living in apartments in Taiwan built with radioactive cobalt get cancer at lower rates than people living in similar apartments but without the radioactive cobalt – what are we to conclude? That the effect of radiation is linear as the strength goes down?

structure (XANES), the absorption K-edge for as-prepared Co(OH)2is quite close to that of CoO, suggesting that the valence of cobalt is +2. (The CoO, purchased from Alfa Aesar, may contain up to 10% Co3O4, which is noted in the label. The existence of Co3O4with higher valence...
