a new tris-chelate cd(ii) complex, [cd(dadmbtz)3](clo3)2 has been successfully synthesized and characterized by ir, 1h, 13c nmr spectroscopy, elemental analysis and single crystal x-ray determination. the thermal behavior, uv-vis and fluorescence spectra of compound were studied. in reaction with dadmbtz, cadmium (ii) forms a tris-chelate complex with nearly c3 symmetry for coordination polyhed...

Natural chlorate (ClO3?) is widely distributed in terrestrial and extraterrestrial environments. To improve understanding of the origins distribution ClO3?, we developed tested methods to determine multi-dimensional isotopic compositions (?18O, ?17O, ?37Cl, 36Cl/Cl) ClO3? then applied samples natural nitrate-rich caliche-type salt deposits Atacama Desert, Chile, Death Valley, USA. Tests with re...

Magnetic resonance force microscopy is combined with spin-echo spectroscopy to obtain spatially and spectrally resolved NMR signals of micrometer-scale objects. The experimental spatial resolution for the demonstration experiment on a sample consisting of Ba(ClO3)2.H2O and (NH4)2SO4 single crystals is 3.4 microm. The spectral resolution of 3.4 kHz is sample limited. Improvements in resolution a...

A distinctive feature of the voltage-dependent chloride channels ClC-0 (the Torpedo electroplaque chloride channel) and ClC-1 (the major skeletal muscle chloride channel) is that chloride acts as a ligand to its own channel, regulating channel opening and so controlling the permeation of its own species. We have now studied the permeation of a number of foreign anions through ClC-1 using voltag...

Chlorine dioxide (ClO2) has emerged as a promising alternative to free chlorine for water disinfection and/or pre-oxidation due its reduced yields of chlorinated byproducts. ClO2 decomposes form chlorite (ClO2−), which influences the following advanced oxidation processes (AOPs) micropollutant abatement in drinking water. This study aims at investigating effects ClO2− on concentrations reactive...

The aim of this study was to better evaluate the impact on-site electro-generated hypochlorite for water disinfection. For venture, daily variability hypochlorite-generating systems and their performance produce low disinfection by-products during formation were observed. Seven installations, selected at different swimming pool facilities in Switzerland. Active chlorine (AC), two chlorate (ClO3...

The unimolecular decomposition of HClO4 has been investigated at the G2M//B3LYP/6-311zG(3df, 2p) level of theory. Above 500 K, the decomposition process was found to depend strongly on pressure below 200 atm. The rate constants at the highand low-pressure limits were predicted to be k1 ‘ ~ 1.5 6 10 exp(226500/ T) s and k1 0 ~ 3.39 6 10 T exp(229430/T) cm molecule s, respectively. Under the atmo...

In papers by Wang et al. (1998), Liu et al. (1999), and Liu and Tsay (2003), it was proposed that Arabidopsis thaliana Nitrate Transporter1.1 (AtNRT1.1; CHL1) encodes a dual-affinity nitrate transporter that “plays a major role in high-affinity nitrate uptake.” Here, we evaluate this concept by reexamining the uptake kinetics of Arabidopsis (Arabidopsis thaliana) mutant lines defective in NRT1....
