Some new mononuclear complexes [ML1L2(NO3)2 ] {where M = [Co(II), Ni(II), Cu(II) and Zn(II)], L1 = 2Hydroxy-5-nitrobenzaldehyde and L2 = diketones (Pentane-2,4-dione, 1-phenylbutane-1,3-dione, 1,3diphenylpropane-1,3-dione)}, have been synthesized and were characterized by elemental analysis, molar conductance, , FTIR spectra, UV, magnetic moment and thermo gravimetric analysis (TGA). The relati...

The hygroscopicity of mineral aerosol samples has been examined by three independent methods: diffuse reflectance infrared Fourier transform spectroscopy, thermo-gravimetric analysis and differential mobility analysis. All three methods allow an evaluation of the water coverage of two samples, CaCO 3 and Arizona Test dust, as a func-5 tion of relative humidity. For the first time, a correlation...

The effects of norepinephrine-induced vasoconstriction on pulmonary extravascular water volume (PEWV) and central volume were studied before and after intravenous volume expansion with 5% dextrose and water (20 ml/kg body weight). PEWV was measured by double isotope dilution and gravimetric analysis and assessed by electron photomicrography. Comparisons were made with saline-treated control dog...

The detection and analysis of proteins in a label-free manner under native solution conditions is an increasingly important objective analytical bioscience platform development. Common approaches to detect often require specific labels enhance sensitivity. Dry mass sensing approaches, by contrast, using mechanical resonators, can operate offer attractive However, such typically suffer from lack...
