Preparation and Instability of Nanocrystalline Cuprous Nitride.

Inorganic chemistry

Reichert MD, White MA, Thompson MJ, Miller GJ, Vela J.
PMID: 26091284
Inorg Chem. 2015 Jul 06;54(13):6356-62. doi: 10.1021/acs.inorgchem.5b00679. Epub 2015 Jun 19.

Low-dimensional cuprous nitride (Cu3N) was synthesized by nitridation (ammonolysis) of cuprous oxide (Cu2O) nanocrystals using either ammonia (NH3) or urea (H2NCONH2) as the nitrogen source. The resulting nanocrystalline Cu3N spontaneously decomposes to nanocrystalline CuO in the presence of both...

Mechanism of the Gibbs Reaction. Part 4.(1) Indophenol Formation via N-Chlorobenzoquinone Imine Radical Anions. The Aza-S(RN)2 Chain Reaction Mechanism. Chain Initiation with 1,4-Benzoquinones and Cyanide Ion.

The Journal of organic chemistry

Pallagi I, Toró A, Horváth G.
PMID: 11674654
J Org Chem. 1999 Sep 03;64(18):6530-6540. doi: 10.1021/jo982113v.

The mechanism of the Gibbs reaction, a colorimetric phenol assay that applies N-chlorobenzoquinone imines 1 in an aqueous basic medium, was investigated. It is concluded that N-chloroimine radical anion 7 generated in a single electron transfer (SET) from the...

Inhibition of Water Splitting Increases the Susceptibility of Photosystem II to Photoinhibition.

Plant physiology

Wang WQ, Chapman DJ, Barber J.
PMID: 16668844
Plant Physiol. 1992 May;99(1):16-20. doi: 10.1104/pp.99.1.16.

Photosystem II (PSII)-enriched membrane particles were isolated from peas (Pisum sativum L.) and treated in several different ways to inhibit the water oxidation reactions, but not reaction center function itself, as judged by the light-induced rate of reduction of...

Regulation of the Photosynthesis Rhythm in Euglena gracilis: II. Involvement of Electron Flow through Both Photosystems.

Plant physiology

Lonergan TA, Sargent ML.
PMID: 16660924
Plant Physiol. 1979 Jul;64(1):99-103. doi: 10.1104/pp.64.1.99.

Rhythmic changes in the light reactions of Euglena gracilis have been found which help to explain the basic reactions effected in the circadian rhythm of O(2) evolution. Diurnal changes in the slope of light intensity plots indicated that the...

Stimulation of Photosystem I Electron Transport by High Concentration of 3-(3,4-Dichlorophenyl)-1,1-dimethyl Urea in Uncoupled Chloroplasts.

Plant physiology

Ramanujam P, Gnanam A, Bose S.
PMID: 16662131
Plant Physiol. 1981 Dec;68(6):1485-7. doi: 10.1104/pp.68.6.1485.

The light saturated rate of photosystem I-dependent electron transport (ascorbate/dichlorophenol-indophenol --> methyl vilogen in presence of 1 micromolar 3-[3,4-dichlorophenyl]-1,1-dimethyl urea [DCMU]) was increased by a high concentration of DCMU added to broken and uncoupled chloroplasts isolated from pea (Pisum...

Light Activation of Purified Aconitase by Washed Thylakoid Membranes of Pea (Pisum sativum L.).

Plant physiology

Mohamed AH, Anderson LE.
PMID: 16662812
Plant Physiol. 1983 Feb;71(2):248-50. doi: 10.1104/pp.71.2.248.

Purified aconitase, an iron-sulfur protein, from either beef heart mitochondria or pig heart can be activated fully by light when combined with washed thylakoid membranes from pea (Pisum sativum L.) chloroplasts. The light activation of the enzyme does not...

Control of the Photosynthetic Apparatus of Acetabularia mediterranea by Blue Light : Analysis by Light-Saturation Curves.

Plant physiology

Wennicke H, Schmid R.
PMID: 16665593
Plant Physiol. 1987 Aug;84(4):1252-6. doi: 10.1104/pp.84.4.1252.

During growth, Acetabularia mediterranea requires the action of blue light to maintain high rates of photosynthesis. In the present study, blue light-dependent alterations of the photosynthetic apparatus, which can be detected by analysis of light-saturation curves and by measurements...
