The interaction between a gas molecule and photocatalyst is vital to trigger photocatalytic reaction. surface state of affects much in this interaction. Herein, adsorption H 2 O molecules on s -triazine-based g-C 3 N 4 was thoroughly studied by first-principle calculation. Although various initial models with multifarious locations were built, the optimized strong energy pointed same configurat...

Pseudomonas sp. strain ADP utilizes the human-made s-triazine herbicide atrazine as the sole nitrogen source. The results reported here demonstrate that atrazine and the atrazine degradation intermediates N-isopropylammelide and cyanuric acid are chemoattractants for strain ADP. In addition, the nonmetabolized s-triazine ametryn was also an attractant. The chemotactic response to these s-triazi...

Four different, well known colour reagents for iron determination were tested in a citrate buffer at pH 2.0 under the same automated standard conditions and compared with a manual reference method on human serum and plasma samples. Specific results were obtained only with the chromogen tripyridyl-s-triazine. A micromethod was developed, which is generally well suited for automated, direct serum...

Growth-promoting action of simazine and other s-triazine herbicides was detected by the use of sorghum (Sorghum bicolor [L]. Moench) callus tissue and the chlorophyll retention test. Soil application of simazine [2-chloro-4, 6-bis(ethylamino)-s-triazine] at sublethal levels nearly doubled the growth-promoting action of sorghum root exudates. Treated plants yielded up to 26% more total protein t...

Sorption of two s-triazines, atrazine and ametryn, by carbonatic soils, Histosols, Spodosols and Oxisols was examined. Linear isotherms were observed and sorption coefficients (K(d)) of both compounds were significantly lower (α = 0.05) onto carbonatic soils compared to non-carbonatic soils. Furthermore, among carbonatic soil types, the marl-carbonatic soils had the lowest sorption affinities. ...

During the reaction between 1,3,5-tris(2-hydroxyethyl)hexahydro-s-triazine and hydrogen sulphide, the principle by-product is the organic sulphide 5-(2-hydroxyethyl)dithiazine. It can be determined by a novel, portable, field-capable ion mobility spectrometry method described herein and enables the "degree spent" to be determined. Dependant upon the level of carbon dioxide in the produced gas, ...

BACKGROUND Enhanced atrazine degradation has been observed in agricultural soils from around the globe. Soils exhibiting enhanced atrazine degradation may be cross-adapted with other s-triazine herbicides, thereby reducing their control of sensitive weed species. The aims of this study were (1) to determine the field persistence of simazine in atrazine-adapted and non-adapted soils, (2) to comp...

Thesis Abstract Triazines represent a promising scaffold for cancer treatment due to their similarity the biologically active purine and pyrimidine systems. Besides, triazines annulated compounds exist in skeleton of numerous natural synthetic chemotherapeutic agents such as Azanucleosides (6-azacytosine 6-azauracil). Also, triazine derivatives proved display antiviral, anti-inflammatory, antim...
