Nafion-Induced Metal-Metal Interactions in a Platinum(II) Terpyridyl Acetylide Complex:a Luminescent Sensor for Detection of Volatile Organic Compounds

Introduction The design of new solid-state sensor materials that can selectively adsorb volatile organic compounds (VOC) and produce measurable color and/or lumines-cence changes is of potential significance in the sense of environmental and public safety control.1-5 The use of metal complexes as optical sensors for VOC detection has been reported, and most of them are based on the susceptibility of metal-to-ligand charge transfer (MLCT) and/or metal-metal-to-ligand charge transfer (MMLC…     

浙江不同地区银杏叶中微量元素的研究

用荧光分光光度法和能量色散X荧光分析法测定了浙江不同地区银杏叶中某些微量元素含量的变化。结果表明:不同地区的银杏叶中微量元素硒、铜、锌、铬、铁和锰的含量范围分别为0.1～2.17×10~(-6),2.8～6.9×10~(-6),6.1～17.1×10~(-6),1.1～6.6×10~(-6),74～399×10~(-6)和15～73×10~(-5).     

Novel pressure and displacement sensors based on carbon nanotubes

We report newly designed pressure and displacement capacitive sensors based on a flexible paper–CNT structure.The carbon nanotube(CNT)powder was deposited on a thin paper substrate and was pressed at an elevated temperature.The sheet resistance of the paper–CNT films was in the range of 2–4 kΩ/cm2.The paper–CNT films were used to fabricate pressure and displacement sensors.The sensitivities of the pressure and the displacement sensors were found to be17.3 p F·m2/k N and 0.93 10-3p F/μm,respectively.The experimental results were compared with the simulated data and they found good agreement with each other.     

Shape resonances in slow electron scattering by aromatic molecules. I. Anthraquinone derivatives

A series of anthraquinone (C(14)O(2)H(8)) derivatives has been studied by means of electron capture negative ion mass spectrometry (ECNI-MS), photoelectron spectroscopy (PES), and AM1 quantum chemical calculations. Mean lifetimes of molecular negative ions M(-.) (MNI) have been measured. The mechanism of long-lived MNI formation in the epithermal energy region of incident electrons has been investigated. A simple model of a molecule (a spherical potential well with the repulsive centrifugal term) has been applied for the analysis of the energy dependence of cross sections at the first stage of the electron capture process. It has been shown that a temporary resonance of MNI at the energy approximately 0.5 eV corresponds to a shape resonance with lifetime 1-2.10(-13) s in the f-partial wave (l = 3) of the incident electron. The next resonant state of MNI at the energy approximately 1.7 eV has been associated with the electron excited Feshbach resonance (whose parent state is a triplet npi* transition). In all cases the initial electron state of the MNI relaxes into the ground state by means of a radiationless transition, and the final state of the MNI is a nuclear excited resonance with a lifetime measurable on the mass spectrometry timescale.
