Neutron time-of-flight scattering
Neutron time-of-flight scattering (meV ~eV) A rotating object called a chopper is used to determine the single neutron energy incident on the sample. The neutron energy after scattering is determined ...
EXSY (Exchange Spectroscopy, NMR)
What is EXSY? Abbreviation for EXchange SpectroscopY, a technique in NMR measurements. Another name for NOESY. The pulse sequences are identical to NOESY.[1,2] Since correlated signals also appear ...
What is DOI?
You have probably seen the above number written in the corner of a paper at least once. This is a code called DOI (Digital Object Identifier). What is DOI? A DOI is a code that corresponds to ...
heavy drug (deuterated drug)
A heavy drug is a drug labeled with deuterium (2H, D).[1] By replacing C-H bonds at metabolic sites in drug molecules with more stable C-D bonds, metabolism can be slowed down. This deuteration makes ...
Process Mass Intensity, PMI
Process Mass Intensity (PMI) is the total mass of material used to produce a product of a given mass, determined in units of mass of input material (e.g., kg) per mass of product (e.g., kg). The PMI ...
