Thulium(III) oxide is a pale green crystalline compound, with the formula Tm 2 O 3. It was first isolated in 1879, from an impure sample of erbia , by Swedish chemist Per Teodor Cleve , who named it thulia .
Thulium is a chemical element; it has symbol Tm and atomic number 69. It is the thirteenth element in the lanthanide series of metals . It is the second-least abundant lanthanide in the Earth's crust, after radioactively unstable promethium .
The TM-score is intended as a more accurate measure of the global similarity of full-length protein structures than the often used RMSD measure. The TM-score indicates the similarity between two structures by a score between ( 0 , 1 ] {\displaystyle (0,1]} , where 1 indicates a perfect match between two structures (thus the higher the better ...
Transverse magnetic (TM) modes No magnetic field in the direction of propagation. These are sometimes called E modes because there is only an electric field along the direction of propagation. Hybrid modes Non-zero electric and magnetic fields in the direction of propagation. See also Planar transmission line § Modes.
Thulium(II) chloride is an inorganic compound with the chemical formula TmCl 2. Production ... 2 TmCl 3 + Tm → 3 TmCl 2. Chemical properties. Thulium ...
Nucleic acid thermodynamics is the study of how temperature affects the nucleic acid structure of double-stranded DNA (dsDNA). The melting temperature (T m) is defined as the temperature at which half of the DNA strands are in the random coil or single-stranded (ssDNA) state.
The transverse Mercator map projection (TM, TMP) is an adaptation of the standard Mercator projection. The transverse version is widely used in national and international mapping systems around the world, including the Universal Transverse Mercator .
In physiology, transport maximum (alternatively Tm or T max) refers to the point at which increase in concentration of a substance does not result in an increase in movement of a substance across a cell membrane. In renal physiology, the concept of transport maximum is often discussed in the context of glucose and PAH. [citation needed]
