OBJECTIVE: To study the acute and chronic toxicity of Tiangou Jiangya capsule. METHOD: Tiangou Jiangya capsule was intragastrically administered to mice twice a day. The appearance, behavior, mental status, respiratory changes of mice and the number of poisoned and dead mice in each group were noted daily for 14 conse…
Tip-enhanced Rayleigh scattering images of Ge quantum dots grown on a Si substrate have been observed at room temperature. Changing the wavelength of the incidence light from 405 to 590 nm, the contrast of the images is reversed. It is found that the scattering intensity depends on the dielectric constants of the mate…
Abstract The treatment of coherent interfaces and cracks is discussed in the framework of dislocation dynamics (DD). In the case of interfaces, we use DD to study dislocation interactions in nanoscale bimetallic laminates, and to predict their structure after relaxation and during loading. In agreement with experiment…
Here we describe a simple physical vapor deposition (PVD) method to prepare large quantity of highly monodispersed perylene nanotablets with a deposition-temperature controlled approach. The nanotablets produced are 1 microm octagon with 100-200 nm thickness. Confocal microscopic images of the nanotablets excited with…
Polypropylene bag industry is labor intensive and faces tremendous labor and machine maintenance problems, which challenge the quality of the fabric. Weaving defects manifest themselves as holes or missing tapes in the fabric, which compromise the strength and usability of the fabric. This technical paper outlines the…
Short interfering RNAs, or siRNAs, belong to a class of RNA species which play a role in both cellular defence and gene regulation. siRNAs are members of a larger RNA interference pathway found within cells and are involved in the degradation of RNAs which possess complementarity to specific target sequences. This pro…
Metal nanoparticles have potential utilities in biochemical sensing applications owing to their localized surface plasmon resonance characteristics. To facilitate the application of localized surface plasmon resonance sensors, a simple and effective interpretation of spectra responses of metal nanoparticles to analyte…
N -derivatives of 4-chloro-3,5-dimethylphenoxyacetamide—2-(4-chloro-3,5-dimethylphenoxy)- N -(4-fluorophenyl)acetamide, 2-(4-chloro-3,5-dimethylphenoxy)- N -(3-chloro-4-fluorophenyl) acetamide, 2-(4-chloro-3,5-dimethylphenoxy)- N -[4-chloro-3-(trifluoromethyl)phenyl] acetamide, 2-(4-chloro-3,5-dimethylphenoxy)- N -[3-…
Te nanowires and butterfly nanostructures have been fabricated by template-free electrodeposition (TFED) in aqueous solution. By high-resolution transmission electron microscopy (HRTEM) study, the favored growth directions of the nanowires and the wings of the butterfly nanostructures were determined to be along the […
Applications of nanomaterials will become the leading technology during the next decades of this century. The composite nanomagnet, which has better features, lower cost and is less demanding of rare earth elements, is a new type of permanent magnetic material. It has become one of the important developments of the na…
A novel layered AgBr-based nanocomposite (designated as AgBr-NC) was prepared using nanosecond pulsed laser ablation in liquids (PLAL) in the presence of cetyltrimethylammonium bromide (CTAB). The obtained layered AgBr-NC possesses well-defined 2D shape. X-ray diffraction (XRD) pattern was composed of a series of peak…
Article Experimental and Finite Element Simulation of MIABWelding of Alloy Steel Tubes in Pressure Parts was published on December 1, 2011 in the journal Journal for Manufacturing Science and Production (volume 11, issue 1-3).
The microstructure and magnetic properties of multilayer [Os(t)/FePt(x)]n films on a glass substrate with a 10 nm Os buffer layer by ion beam sputtering have been studied as a function of the annealing temperatures between 300 and 800 degrees C. Here, t = 0.2, 1 or 5 nm and x varied from 10, 20, 25, 50, to 100 nm with…
We have fabricated and investigated the effect of CdSe/ZnS quantum dot (QD) concentrations on the performance of self-assembly hybrid inorganic/organic light emitting diodes (QD-OLEDs). The uniform distribution of QDs with controllable density was achieved using the conventional spin-coating method. There was a QD thr…
The effects of adding lanthanum to the nickel-based anode on the cell performances were studied. Because lanthanum can react with nickel and zirconium, it can hinder the sintering of nickel and yttrium stabilized zirconium (YSZ) and improve the interfacial contact between Ni and YSZ on the anode. When 10% (mol) lantha…
Einleitung: Engineered metal oxide nanoparticles are produced at tons scale already. Since the miniaturization of materials into the nano-size range may dramatically change physical and chemical properties, nanomaterials will obviously also interact in a different way with biological systems. Once they entered the bod…
Aggressive scaling of silicon technology over the years has pushed CMOS devices to their fundamental limits. Pioneering works on carbon nanotube during the last decade possessing exceptional electrical properties have provided an intriguing solution for high performance integrated circuits. So far, at best, carbon nan…
Since the combustion flame method using acetylene/oxygen is a high rate diamond synthesis process can be conducted in open air, this process is thought to be useful for low cost diamond production. In this study, to develop a method for diamond synthesis on a thick and/or complicated shape article, diamond depositions…
【The polarizer is an important optical element used in a variety of applications. Nano-wire grid polarizers in the form of sub-wavelength metallic gratings are an attractive alternative to conventional polarizers, because they provide high extinction ratio. This study has been carried out to fabrication of the 17inch…
The 7-methyl- cis -2-(1’-naphthyl)-2,3,4,5-tetrahydro-1 H -benzo[ b ]azepin-4-ol (chemical formula C 21 H 21 NO) was prepared via the reductive cleavage of the bridged N-O bond of the corresponding 7-methyl-2- exo -(1′-naphthyl)-1,4-epoxytetrahydro-1-benzazepine. The X-ray powder diffraction pattern for the new compou…
