A sequential and general strategy has been successfully developed for the synthesis of spiropyrazolone scaffolds. This intriguing transformation of the asymmetric multicomponent catalysis process was realized with the combination of Michael addition/chlorination/nucleophilic substitution in a one-pot sequence, giving rise to a series of spiropyrazolones with fully substituted cyclopropanes and spiro-dihydrobenzofurans containing continuous stereogenic centers in good yields with excellent stereoselectivities.

The current work investigates the performance of a real-time scan conversion algorithm for generating a 2-D ultrasound image from a laterally scanned single-element ultrasound transducer, which has applications in point-of-care devices such as for skin imaging. The algorithm employs a fixed calibration curve to update a predefined image grid in real time. Simulations showed that the calibration curve (with a maximum of 1) is robust to changes in scatterer concentration (8.3 x 10(-3) mean absolute error), signal to noise ratio (1.0 x 10(-3) mean absolute error for -5 dB SNR), and can be accurately predicted from a small number (31) of point scatterers (6.9 x 10(-3) mean absolute error). Good agreement was also found between the calibration curves obtained from simulated and experimental data (1.19 x 10(-2) mean absolute error). The scan conversion algorithm was validated by evaluation of the position estimation errors on both simulations and experiments. Clinical images of skin lesions (N = 20) demonstrate the feasibility of the algorithm for real, non-homogeneous tissue. Use of a fixed calibration curve compared to an adaptive calibration curve gave similar accuracies in the scanning step size range of 150-350 mu m (with an average overlap of the accuracy ranges of 92.94% for simulations and 42.83% for experiments), and a 350-fold improvement in computation time.

A series of pyrazole ligands named as 1,4-bis(3,5-dimethylpyrazol-1-yl)butane (bbd), 1,3-bis(3,5-dimethylpyrazol-1-yl)propane (bdpp), and 1,3-bis(3,5-dimethylpyrazol-1-yl)propane-2-ol (bdpo) along with their transition metal complexes including [Cu-2(mu(3)-SCN)(2)(mu-bbd)](n), [Cu-2(mu(3)-SCN)(2)(mu-bdpp)](n), and [Cu2Hg(mu(2)-SCN)(2)(bdpo)(2)(CH3COO)(2)](n)were synthesized and characterized using FT-IR and Uv-vis spectroscopies, as well as thermal gravimetric analysis. The prepared compounds were investigated as corrosion inhibitors to protect mild steel in 0.5 M H(2)SO(4)solution. Corrosion tests were performed by electrochemical impedance spectroscopy and potentiodynamic polarization measurements. The pyrazole ligands exhibited inhibition efficiencies in a range of 38-78%, which introduced them as moderate inhibitors. On the other hand, the pyrazole complexes showed inhibition efficiencies higher than 85%, demonstrating their high potentials to mitigate the steel corrosion. In addition, the bimetallic complex resulted in higher corrosion resistance than the two monometallic complexes. This was evidence of a critical role of the coordinated metal of the complex in forming an adhesive protection film on the steel surface.
