J. J. Thomson that the accepted atomic weight of cobalt, namely 59.0, is probably too high, and that the true atomic weight of cobalt is less than that of nickel. Prof. Thomson's suggestion was founded on the results observed with secondary radiation....
The results of the three series were practically identical, the atomic weight of cobalt being 58*99 (O = 16).\nWhile recognising that data obtained from one compound only are not sufficient to finally settle the atomic weights of these metals, the authors conclude that if " gnonaium " ...
I was looking up the atomic weight of Cobalt from 2 different resources. I noticed that there was a slight disparity between wikipedia.org and webqc.org. I then looked up the values for Oxygen, Carbon, and Hydrogen. http://www.webqc.org/periodictable-Cobalt-Co.html ...
both of which are further subdivided into the categories heat-treatable and non-heat-treatable. related elements hydrogen nickel neon potassium helium copper sodium calcium lithium zinc magnesium scandium beryllium gallium cobalt titanium boron germanium silicon vanadium carbon arsenic phosphorus chromium nitro...
Cobalt bomb A nuclear bomb designed to produce more than the usual amount of deadly radioactive fallout, i.e., an enhanced-fallout weapon. The technical term is "salted bomb." The weapon is basically a conventional nuclear device encased in a jacket of cobalt or or zinc. Cobalt bombs are...
The colonists—named for the largest family, the Robinsons— have been willing to pay a premium price for Sykes' asteroid. His certified assays show that S1011 has an especially high water content of 18%, and unusually high concentrations of tantalum, and cobalt. For extra bonus money and a...
Ar° of Ho, Tb, Tm and Y were changed in 2017 and again updated in 2021: Al (aluminium), 2017: from 26.981 5385 ± 0.000 0007 to 26.981 5384 ± 0.000 0003 Au (gold), 2017: from 196.966 569 ± 0.000 005 to 196.966 570 ± 0.000 004 Co (cobalt), 2017: from 58.933 194 ± ...

Synthesis and characterization of the Co-NG catalyst To prepare the Co-NG catalyst, a precursor solution was first prepared by sonicating GO and cobalt salts (CoCl2·6H2O; weight ratio GO/Co=135:1) in water. The well-mixed precursor solution, as depicted in Fig. 1a, was then freeze-drie...
We dynamically weight the contribution of false positives and false negatives to the loss function to overcome a dataset imbalance in the early epochs and to suppress false positives at the later stages of training. As a significant portion of the pixel values in most training images are close ...
