A grain boundary is also observed, with segregation of Zn, Mg, and Cu relative to the matrix, Fig. 2c. The content of O is low, with about 0.3 at.% both in the matrix and at the grain boundary. We characterized the oxide composition in bulk and at the grain boundary, ...
giving it a relatively high atomic number of 79. It achieves a relative atomic mass of 196.96657u at 20 degrees Celsius. You can calculate troy ounces by multiplying every ounce by 0.911458, or you can take the easy route by using a mass value calculator. A standard 12.4-kilogram bar is ...
Why reprex? Getting unstuck is hard. Your first step here is usually to create a reprex, or reproducible example. The goal of a reprex is to package your code, and information about your problem so that others can run it…
This function changes the position that the next read or write will occur from. You should not seek before or after the database, doing so will result in an error. Seeking is always relative to the start of the file, the optional offset specified in the CDB options structure being added ...
Protein crystal structures are potentially over-interpreted since they are routinely refined without any restraint on the upper limit of atomic B-factors. Consequently, some of their atoms, undetected in the electron density maps, are allowed to reach extremely large B-factors, even above 100 square...
