Measurements of the electrical resistance of NdH 9 demonstrate a possible superconducting transition at ∼4.5 K in P6 3 /mmc-NdH 9.
I4/mmm-NdH 4 and C2/c-NdH 7 are stable from 135 to 85 GPa, and P6 3 /mmc-NdH 9 is stable from 110 to 130 GPa. Substituted cathinones (also known as cathinones or synthetic cathinones) are a chemical class of psychoactive compounds that are based on the structure of cathinone.The class is composed of all the derivative compounds of cathinone which can be formed by replacing, or substituting, one or more hydrogen atoms in the cathinone core structure with substituents.
