Resonance Scattering Effect of Dopamine Product Particle and Its Application to Polyphenoloxidase Activity Assay [PDF]

Chinese Journal of Chemistry, 2011
AbstractIn pH 7.2 Na2HPO4‐NaH2PO4 buffer solution, polyphenoloxidase (PPO) could catalyze the oxidization of dopamine (DA) to form polymer particles in dark‐red color, which exhibited a strong resonance scattering (RS) peak at 780 nm. In the chosen conditions, as the PPO activity increased, the RS intensity at 780 nm increased linearly.

Particle correlations in the multiperipheral resonance production model for the case of brokenSU 3 symmetry

Il Nuovo Cimento A, 1978
Particle correlations are calculated in the multiperipheral resonance production model for the brokenSU3 symmetry, by using the generating-function technique. The two-particle correlations for ππ, Kπ and KK\(\left( {K\bar K} \right)\) productions are presented.

Nuclear reactions with resonant-particle production

Nuclear Physics A, 1973
Abstract The observation of resonant-state products in nuclear reactions by measurements of coincidences between decay partners is proposed as a general spectroscopic tool for nuclear physics. The importance of the kinematic confinement of final-state resonant systems to a cone in the laboratory system is discussed and applied to various resonant ...

Effects ofN*(1440) resonance on particle production in heavy-ion collisions at subthreshold energies

Physical Review C, 1994
We study quantitatively the effects of the [ital N][sup *](1440) resonance on the production of kaons, antikaons, and antiprotons in heavy-ion collisions at subthreshold energies. It is found that baryon-baryon collisions involving the [ital N][sup *] have minor effects on the production of kaons and antikaons.

Resonant statistical model of particle production

Il Nuovo Cimento, 1962
The statistical model modified to include resonant interaction is discussed. It is shown that arbitrary mass-squared distributions calculated from Lorentz invariant phase space can be expressed as a product of two phase-space factors. Expressions arising in the modified model are reduced to either products of phase-space factors or simple integrals ...

Application of the spinning technique to the production of high beta seamless superconducting resonators for particle accelerators

IEEE Transactions on Appiled Superconductivity, 1995
Superconducting resonators for high beta particle accelerators are multicell structures made of niobium or of niobium-sputtered copper. In both cases the resonator bases are traditionally fabricated by spinning or deep drawing half-cells and electron-beam welding them together at the level of the equator; cells are then welded to one another at the ...

Near-Threshold Particle Production: A Probe of Resonance-Matter Formation in Heavy-Ion Collisions

, 1994
The observation of the lowest excited state of the nucleon, the Δ-resonance, by Fermi and collaborators1 in 1952–55 was the first experimental evidence for an internal structure of the nucleon. It took another 15 years until Friedman, Kendall and Taylor2 discovered quarks and gluons as constituents of the nucleon in their pioneering experiments on ...
