Web1977-01-01. 1. The metallochromic indicator dye, arsenazo III, was injected intracellularly into Limulus ventral photoreceptor cells to concentrations greater than 1 mM. 2. The absorption spectrum (450-750 nm) of the dye in single dark-adapted cells was measured by a scanning microspectrophotometer. WebPotentiometric response of the biosensor was examined as a function of the different concentrations of urea solution, and linear concentration range of urea was demonstrated in the range of 0.01 mM-500 mM. The detection limit was also investigated and measured as 0.77 µM. Response time of the biosensor was also determined as 30 s.
WebThe color of naturally colored silk (NCS) fades easily during home washing due to the loss of pigment accompanied by dissolution of the sericin. In this study, phytic acid was used to cross-link the sericin of NCS and reduce its solubility, aiming at improving the color fastness of NCS to repeated washing. It was found that the sericin-fixing effect increased as the … WebLaunched startup company Potentiometric Probes, which develops fluorescent sensors of electrical activity in cells and tissues with applications in neuroscience and cardiac research as well as...

Web14 Apr 2024 · In order to characterize the bending jet, we track the evolution of a jet trajectory at the onset of a bending jet. At an early stage, small perturbation amplifies with time in space such that the first jet bend occurs at the jet end. The initial waves propagate at the growth rates of ki ∼ −10 2 m −1 and ωi ∼ 10 Hz. commonwealth insurance groupWebThis Paper describes the determination of acids and bases present in petroleum asphaltenes by differential non-aqueous potentiometric titrations. The acids and bases are split into differing pKa's by addition of model compounds.
