The GH3 family of acyl-acid-amido synthetases catalyze the ATP-dependent formation of amino acid conjugates to modulate levels of active plant hormones, including auxins and jasmonates. Initial biochemical studies of various GH3s show that these enzymes group into three families based on sequence relationships and acyl-acid substrate preference (I, jasmonate-conjugating; II, auxin- and salicyli...

The first flow synthesis of a range coinage metal amido and thiolato complexes are reported. Mild conditions extremely short reaction times provide efficient sustainable access to these valuable organometallic species.

A aveia pertence ao gênero Aveneae da família Gramineae, é um cereal de clima temperado e 60% matéria seca do grão composta amido. Cada fonte amido natureza única apresentam características diferentes que determinam sua adequação a uma aplicação específica. O destaca-se por garantir benefícios em suas aplicações tecnológicas possibilidade extração várias fontes vegetais. Neste cenário, os cerea...

To determine the trans effect on the rates of reductive eliminations from arylpalladium(II) amido complexes, the reactions of arylpalladium amido complexes bearing symmetrical and unsymmetrical DPPF (DPPF = bis(diphenylphosphino)ferrocene) derivatives were studied. THF solutions of LPd(Ar)(NMeAr') (L = DPPF, DPPF-OMe, DPPF-CF3, DPPF-OMe,Ph, DPPF-Ph,CF3, and DPPF-OMe,CF3; Ar = C6H4-4-CF3; Ar' = ...

A thermoplastic polyurethane (TPU) nanocomposite was synthesized based on Maghnite as an inorganic reinforcement phase. The result of this study to evaluate the gas barrier properties a material containing clay nanoparticles. preparation prepolymer with NCO terminations carried out using in situ solution polymerization method. has already been modified by intercalation 12-amino decanoic acid mo...

The mechanical properties of non-vulcanized natural rubber and dialyzed natural rubber-clay nanocomposites have been studied by uniaxial deformations to evaluate the reinforcement efficiency of the clay. We show that while non-rubber molecules contribute to auto-reinforcement, removal of these molecules improves significantly the performance of clay as reinforcement agent. These mechanical prop...

[1] To understand the aqueous history of Mars, it is critical to constrain the alteration mineralogy of the Martian surface. Previously published analyses of thermal infrared (l = 6–25 mm) remote sensing data of Mars suggest that dark regions have 15–20% clay minerals. However, near-infrared (l = 1–3 mm) spectral results generally do not identify widespread clay minerals. Thermal infrared detec...

A unique poly(amido amine) (PAMAM)/polymer dots (Pdots)/NiO heterostructure is developed for photocathodic detection of tyrosinase (TYR), which applicable to TYR in actual human serum samples.
