The oxygen nonstoichiometric model was constructed by introducing one oxygen vacancy for the Σ11 and two oxygen vacancies for the Σ13 GB at the GB regions, of which the number of vacancies introduced was estimated from the EELS experiment. The resultant GB structures obtained from calculation ...
Before 1961 there were two definitions for atomic mass unit. The elements defined the atomic mass unit as '1/16th of the atomic weight of oxygen'. Apart from the fact that the term mass should have been used instead of weight, this definition does not specify which oxygen isotope, and imp...
Metastable phase two-dimensional catalysts provide great flexibility for modifying their chemical, physical, and electronic properties. However, the synthesis of ultrathin metastable phase two-dimensional metallic nanomaterials is highly challenging, mai
Synthesis and characterization of Li(Ni1/3Co1/3Mn1/3)0.96Si0.04O1.96F0.04 as a cathode material for lithium-ion battery The layered cathode materials of LiNi 1/3Co 1/3Mn 1/3O 2 were prepared at 770 °C under oxygen atmosphere using the precursor of (Ni 1/3Co 1/3Mn 1/3)(OH) ...

Artificial transmutation became a thing in the 1930s after scientists converted nitrogen into oxygen. After a couple of celebratory beers, they decided to fire a neutron at a uranium nucleus just to see what happened. The result is known as nuclear fission. This experiment revealed more about th...
