NTR femtosecond, atmosphere, Å/ns, kcal/mol, kcal/mol/Å^2

[fathoni]

Dear UO Team,

I'd like to reuse UO and would like to propose the following new terms to be added to UO:

Femtosecond

Preferred term label: femtosecond
Synonyms: fs
Definition: An SI unit of time equal to 10^-15 seconds or one quadrillionth of a second.
Parent term: second-based unit (UO:1000010)

Atmosphere

Preferred term label: atmosphere
Synonyms: atm
Definition: A unit of pressure defined as 101,325 pascals (Pa) or 1.01325 bar, approximately equal to the average atmospheric pressure at sea level on Earth.
Parent term: pressure unit (UO:0000109)

Angstrom per nanosecond

Preferred term label: angstrom per nanosecond
Synonyms: Å/ns, angstrom/nanosecond
Definition: A unit of velocity, representing one angstrom (10^-10 meters) of distance traveled per nanosecond (10^-9 seconds) of time. It is commonly used in molecular dynamics simulations and studies of atomic-scale processes.
Parent term: velocity unit (UO:0000060)

Kilocalorie per mole

Preferred term label: kilocalorie per mole
Synonyms: kcal/mol, kilocalorie/mole
Definition: A unit of energy per amount of substance, defined as one kilocalorie of energy (1000 thermochemical gram calories) per one mole of substance. It is commonly used in chemistry and biology for thermodynamic quantities.
Parent term: energy unit (UO:0000111) (?)

Kilocalorie per mole per square angstrom

Preferred term label: kilocalorie per mole per square angstrom
Synonyms: kcal/mol/Å^2, kilocalorie/mole/angstrom^2
Definition: A unit of energy per amount of substance per area, commonly used in molecular dynamics simulations for expressing force constants and restraint weights.
Parent term: energy unit (UO:0000111) (?)
