AbstractA general survey of the reaction of neutral red upon a selected series of living animal organisms is made, and the rationale indicates that neutral red is an indicator of proteolytic enzyme action, whether this be intra‐ or extracellular. Cellular hydrolytic and cellular synthetic systems are thus manifested.

Experimental studies of ion-neutral reactions are often carried out with specific applications in mind, for instance atmospheric or laser plasmas. Well-developed experimental methods are available in the form of flow tubes, ion-cyclotron resonance methods, ion drift tubes, and ion beam techniques, all of which have been employed extensively.

Cyclen-catalyzed Henry reaction under neutral conditions
Tetrahedron Letters, 2010A convenient cyclen-catalyzed Henry reaction of aldehydes with nitroalkanes under mild and neutral conditions is reported. This procedure constitutes the first cyclen-catalyzed synthesis of nitroalcohols and is adapted to the condensation of both aromatic and aliphatic aldehydes with nitromethane in THF at room temperature without addition of ...

Photo-Fenton Reaction at Near Neutral pH
Environmental Science & Technology, 2009The photo-Fenton reaction, oxidation of photoproduced ferrous iron by hydrogen peroxide, produces reactive oxidants that may be important to degradation of biologically and chemically recalcitrant organic compounds in surface waters at circum-neutral pH. Sufficient Fe(II) for the photo-Fenton reaction was produced in situ at two field sites (pH 6.1-7.1)

Catalytic Phosphite Hydrolysis under Neutral Reaction Conditions
Inorganic Chemistry, 2018Cationic phosphametallocene-based platinum(II) aqua complexes were used as efficient precatalysts for the hydrolysis of aromatic and aliphatic tertiary phosphites under neutral reaction conditions at room temperature, leading to the selective cleavage of one P-O bond of the phosphite.

Neutrino neutral current reactions in 12C
Annals of Physics, 1985The differential and total cross sections for the nuclear reaction νμ + 12C (g.s) → 12C∗ (1+; T = 1, 15.1 MeV) + νμ are investigated for values of 50 ≤ Eνμ ≤ 300 MeV. An effective Hamiltonian for the above nuclear reaction is constructed from the neutrino-quark neutral current weak interaction, by first constructing the neutrino-nucleon neutral current

Reactions between neutrals clustered on ions
The Journal of Chemical Physics, 1982The observation of a new kind of gas phase chemical reaction is reported. The reactions of O3 and N2O5 molecules with NO are greatly enhanced when the O3 and N2O5 molecules are clustered to chemically weak alkali ions. The alkali ions do not participate in chemical bonding but simply lower the activation energy for neutral reactions by the ...

Negative-Ion—Neutral Reactions
1972This chapter is concerned principally with two-body reactions between negative ions and neutral molecules at low energies in the gas phase. Introductory material on the formation and disappearance of negative ions is also included. Emphasis is placed on results arising from the use of mass spectrometer ion sources or double mass spectrometers as the ...
