Saturation transfer contrast (STC) techniques have been employed to decrease the signal intensity of observed water by saturating a broad proton component. The STC pulse, generally spatially nonselective, reduces the signal of brain background tissue

Carbon dioxide is trapped by (5,10,15,20-tetraphenylporphinato) aluminum acetate in the presence of a secondary amine in the form of an aluminum carbamate on the opposite side to the acetate group with respect to the porphyrin plane. Carbon dioxide t

3,9-Bis(2-(3-(3-tert-butyl-4-hydroxy-5-methylphenyl)propionyloxy)-1, 1-dimethylethyl)-2,4,8,10-tetraoxaspiro[5.5] undecane (Sumitomo's new antioxidant: Sumilizer GA-80) is shown to have a very effective synergistic stabilizing effect in combination w

By a model accelerated oxidative reaction and product analysis, 2-tert-butyl-6-(3-tert-butyl-2-hydroxy-5-methylbenzyl)-4-methylphenyl acrylate (Sumilizer® GM) was found to give a stilbene quinone-type colored product through a quinone methide-type i

A gradient field is applied in a coronal scheme such that a slice region along the flowing direction of a blood vessel, i.e., along the body axis is set as an imaging area. Of regions adjacent to the imaging region in the body axis direction, a regio

2-Tert-butyl-6-(3-tert-butyl-2-hydroxy-5-methylbenzyl)-4-methylphenyl acrylate (Sumilizer GM) is shown to be a very effective stabiliser for thermal degradation of butadiene type polymers under an oxygen-free atmosphere. The stabilising mechanism is

N-Methyltetraphenylporphinatozinc ethyl reacts with carbon dioxide in the presence of secondary amine or alcohol to form novel metalloporphyrins containing metal carbamate or carbonate group. Some of these reactions are accelerated remarkably upon ir

Selective excitation is used to excite to resonance nuclear spins in a predetermined planar slice of a target. The received NMR signals are then used to correct non-homogenity of a static magnetic field based upon the calculated spin-spin relaxation
