A simple and flexible strategy is presented to fabricate the Ag nanoplate-built hollow microsphere arrays with centimetre-squared scale, based on electrodeposition onto Au-coated monolayer colloidal crystal template. The array consists of periodically arranged micro-sized spheres, which are built by vertically standing cross-linking nanoplates. nanoplates single in structure, several hundred nanometres planar dimension about 30 nm thickness. number density size silver can be controlled...
Fentanyl widely used in clinics as practices is potentially utilised an incapacitant countering terrorism and its analogues would be addictive drug, so the degradation of these compounds need to investigated for protecting environment human health. In this work, fentanyl was examined a series oxidant aqueous solutions. Meanwhile, pathways solution were discussed according all products identified by GC/MS LC/MS. Defence Science Journal, 2011, 61(1), pp.30-35 , DOI:http://dx.doi.org/10.14429/dsj.61.68
The chemical weapon sulfur mustard (SM) is a blister agent, and currently, there no effective antidote.To evaluate the decontamination efficacy of potassium ketoxime against SM preliminarily elucidate its mechanism.Potassium reacted with SM, residues were tested at different time intervals by T-135 colorimetry after reaction. Rabbit skin was topically exposed to 2 mg/cm(2) treated 1 min later, observed 6, 12, 24 h. Gas chromatography-mass spectroscopy employed screen identify main products...
The paper presents a newly developed high-yield micro-fabrication technology for single-crystalline silicon atomic force microscope (AFM) probes. Both the tips and cantilevers are simultaneously formed by masked–maskless combined anisotropic etching process. Compared to conventional tip-to-cantilever sequential fabrication scheme, this tip-and-cantilever simultaneous formation can effectively increase yield avoiding damaged during following processed photolithographic steps defining...
The photoassisted reaction of sulfur mustard (HD) in both the vapor and droplet states under UV light irradiation was investigated. It found that HD molecules either gas or condensed phase could be easily converted into other chemicals a germicidal lamp. products detected upon suggested produced kind nontoxic heavy polymer, this method seemed to applicable for decontamination air. Nevertheless, droplets would produce series containing -SCH2CH2Cl -OCH2CH2CI groups, some which were proven even...
A study has been done to examine the degradation of sulfur mustard (HD) and sarin (GB) over hardened cement paste (HCP). The HCP behaved as a typical base like CaO Ca(OH)2. sites were not entirely poisoned by H2O CO2 in air, about 0.47 mmol/g could still be evidenced chemisorption CO2. large amount water irreversibly adsorbed was experimentally demonstrated. Ten kinds products through hydrolysis SN1 (C−Cl), elimination E1 or E2 (C−Cl, C−H), addition−elimination (A−E) under action from HD...
Degradation of sulfur mustard (HD), S-2-(di-isopropylamino)ethyl O-ethyl methylphosphonothioate (VX) and Soman (GD) in water by bleaching powder was investigated. The degradation products were comprehensively analyzed gas chromatography/mass spectrometry (GC/MS), liquid (LC/MS) ion chromatography. pathways deduced based on the identified products. product analysis results indicated that HD could be degraded through oxidation chlorination reactions, a small portion atoms mineralized into...
The kinetics of absorption, desorption, and degradation sulfur mustard (HD) in alkyd coating was experimentally studied, a one-dimension mass transfer model for the transportation HD molecule established on experimental data. obtained results indicated that persistence could be greatly increased due to absorption droplets by coating, there still occurred desorption as vapor from more than 3 days even after decontamination onto coating. It also shown majority both absorbed desorbed...
The degradation or removal of chemical, biological, and radioactive contaminants is a supporting technique for homeland defense countering terrorism. A highly efficient, noncorrosive, nonaqueous formula based on alkali, alcohol, amine was developed chemical warfare agents (CWAs). optimized consisted 50% ethanolamine, 9% benzyl 2% KOH, 28% dimethyl sulfoxide, 11% 18-crown-6-ether, the decontamination efficiency against mustard (HD). experimental results suggested that volume ratio...
A photoassisted reaction of O-ethyl S-[2-(diisopropylamino) ethyl] methylphosphonothioate (VX) droplets in air was carried out. The experimental results indicated that VX could be easily and chemically transformed into other compounds under irradiation a germicidal lamp over sufficient time. Quantum chemical calculation demonstrated UV light less than 278 nm wavelength possibly initiate photoreaction both P-S P=O bonds the molecule were lengthened. identification products by gas liquid...
The peroxide-based decontaminants had attracted great attention for degradation of chemical warfare agents (CWAs) because their high performance, non-corrosive and environmental-friendly merits. Hydrogen peroxide can be activated by some organic activators to enhance the oxidation ability. In this work, a novel formula based on sodium percarbonate (SPC) complexed with 1-acetylguanidine (ACG) was investigated decontamination sulfur mustard (HD) VX as CWAs. experimental results, active species...
Reported is a novel technique to analyze the surface-stress generated during SAM (self-assembled molecule-layer) modified on solid-surface. The individual contribution from three interaction layers, i.e. surface/head-group interfacial layer, molecular chain/chain layer and tail-group/medium can be quantitatively extracted. quantitative extraction implemented by testing self-assembly induced for group of related SAMs with cantilever sensors. helps reveal SAM-based nanomechanical sensing...
On the basis of existing Ion Mobility Spectrometry (IMS) technology, significant improvements have been made in drift tube design, gas path system structure, ionization source choice, and display screen.Then, a series experiments on Sarin (GB), Mustard gas(HD), Hydrogen cyanide (AC) VX detection launched, whose results indicated that improved Spectrometer had good performance fast response speed, easy rinse, low temperature environment adaption with high resolution sensitivity.
