Tissue Equivalent Curved Organic X‐ray Detectors Utilizing High Atomic Number Polythiophene Analogues [PDF]

open access: yesAdvanced Science, 2023
Organic semiconductors are a promising material candidate for X‐ray detection. However, the low atomic number (Z) of organic semiconductors leads to poor X‐ray absorption thus restricting their performance.

The Highest Atomic Number [PDF]

open access: bronzeNature, 1932
IT has been suggested (I believe by Sommerfeld) that the highest possible atomic number is the constant According to Eddington's theory, this number represents the number of degrees of freedom of a system of two charges. It is natural to suppose that there is a correspondence (direct or indirect) between degrees of freedom and independent wave ...
