Photosensitizing supramolecular assemblies based on a phenazine derivative (PPA) have been developed, which show strong affinity toward Pd2+ ions to generate ensemble [email protected] nanoparticles (NPs). The NPs catalyse the Suzuki cross-coupled reaction under mild conditions (aerial conditions, mixed aqueous media, and visible light radiations). Although exhibit for arylboronic acid could ho...

Aromatic prenyltransferases from cyanobactin biosynthetic pathways catalyse the chemoselective and regioselective intramolecular transfer of prenyl/geranyl groups isoprene donors to an electron-rich position in these macrocyclic linear peptides. These enzymes often demonstrate relaxed substrate specificity are considered useful biocatalysts for structural diversification Herein, we assess donor...

Basic understanding of the process of coolant heat transfer inside an engine is an indispensable prerequisite to devise an infallible cooling strategy. Coolant flow and its heat transfer affect the cooling efficiency, thermal load of heated components, and thermal efficiency of a diesel engine. An efficient approach to studying cooling system for diesel engine is a 3D computational fluid dynami...

without any doubt, one of the strategies to achieve knowledge-based economy is the transfer of high technologies and turning them into a competitive stable advantage for companies. technology readiness levels, as a determining factor for high-tech transfer, has not been taken into consideration in recent studies. in this paper the author seeks to identify and prioritize factors affecting the tr...

this research aimed to examine the effect of sequential stimuli technique on acquisition, retention and transfer of ocular motor sequence. first sequential stimuli, time record, response error software was designed. 60 right-handed novices (15-18 years) were divided into five groups (blocked – explicit, blocked – implicit, random – explicit, random-implicit and control). all groups performed a ...

turbulence structure on the gas side of a wavy stratified flow was experimentally investigated in a near horizontal 18.7 cm (h) 10 cm (w) 5.5m (l) rectangular duct.by applying the variable interval time averaging (vita) technique to the hot wire anemometer measurements frequency of occurrence of turbulent events were detected near the air-water interface. experimental results showed that freque...

1. The stoicheiometry of the photo-oxidation of succinate by chromatophores has been investigated with [2,3-(14)C(2)]succinate. It was found that there is a stoicheiometric relationship between the amount of succinate oxidized and the NAD reduced, and that fumarate is the only product of succinate oxidation. 2. The possibility of a direct hydrogen transfer from succinate to NAD in this reaction...

The stereochemistry and mechanisms of hydrogen-transfer reactions catalyzed by the Pseudomonas aeruginosa pyridine nucleotide transhydrogenase have been investigated. In the presence of specific tritimn-labeled pyridine nucleotides, the Pseudomonas transhydrogenase is able to catalyse a direct hydrogen transfer between the reduced and the oxidized pyridine nucleotides. The reduction of DPNf inv...
