The reaction of nerve endings in the median eminence of the rat to zinc iodide-osmium tetroxide (ZIO) staining was examined electron microscopically under normal and experimental conditions. The experimental condition of catecholamine exhaustion in the nerve endings was induced by the administration of ...
Here we directly coupled N2 and CO2 in H2O to produce urea under ambient conditions. The process was carried out using an electrocatalyst consisting of PdCu alloy nanoparticles on TiO2 nanosheets. This coupling reaction occurs through the formation of C–N bonds via the thermodynamically spontaneous ...
point defects; nanophase; normal strain; morphology; simulation Graphical Abstract 1. Introduction An irradiation cascade reaction produces point defects in crystal materials. Point defects are either intrinsic, as with vacancies, interstitial atoms, and their small clusters, or extrinsic, as with ...
A separate set of melatonin-treated and untreated seeds for stress and control treatments were sown directly in pots. The recommended dose of fertilizer was applied to the crop. The plants were allowed to grow under normal conditions until the flowering stage for stress imposition. 4.2. Treatment...
Reaction orders with respect toaBA andbH2,cArrhenius plots showing apparent activation barriers, anddH2-D2exchange results of (i) Pt/TiO2and (ii) Pt/TiO2-450. Reaction conditions for (a) and (b): 60 °C, 3 mL n-hexane, H2pressure: 1–30 bar, BA concentration: ~3–10 mg...
Under normal conditions, peach fruit ripening has been associated with changes in the expression of genes that code for cell wall degradation enzymes and the subsequent changes in enzymatic activity [9–11]. Various studies have provided correlative evidence that wooliness is associated with an ...
