Based on Mie scattering theory,we design three kinds of nanostructures (Au,Au-dielectric,dielectric-Au)and study the effects of the structure parameters and the background refractive indexes on optical scattering properties of nan

Pesticide residue is a significant problem in agriculture that greatly affects human health and life safety.Therefore,it is an urgent need to develop simple and effective method for the rapid detection of trace pesticide residue.I

In this work,a popcorn-like Au@Ag core-shell superstructure was synthesized using dopamine dithiocarbamate (DDTC)as reducing agent to control the discontinuous overgrowth of the Ag nanoparticles onto Au nanocubes (Au NCs).The popc

CS2 gas is not only an atmospheric odor pollutant,but also a crucial characteristic gas for fault diagnosis of Gas Insulated Switchgear.However,the temperature change in the detection environment directly affects the accuracy of t

A bronze mirror of Tang dynasty,were send to scientific analysis by three-dimensional microscopy,SEM-EDS and Raman spectrum analysis.The results indicated that:Ceruse,dolomite and crystal etc.were embedding in the bronze mirror;Th

In order to make up the shortage of calibration of visibility meter,built a suit of open path visibility calibration system device based on laser cavity enhanced technique.The calibration of the forward scattering visibility meter

To study the classification of on-site residual handkerchief paper plastic packaging bags,35 samples of different brands,different series and different colors were tested by Raman spectroscopy.According to the absorption peaks in

Three-dimensional chiral shell-like silver nanostructures are fabricated by micro-sphere self-assembly and tilted vacuum thermal deposition techniques,and the nonlinear saturation absorption characteristics of the sample are inves

Integral Imaging is a technique used to reconstruct light field in real space,which is capable for multi-viewers at the same time,and no additional accessory is needed and is easy to build as well,so it has the potential to be wid

Yujiaba site is one of the most important Ba sites in the Three Gorges area.It is located at the northeast of Yujiaba,Kaizhou Disctrict,Chongqing and was discovered in 1980s.Burial objects characterized by bronze weapons have been

A kind of crafts called “elephant bone” is very common in nowadays′jewelry market.It is impossible for us to identify it only by conventional techniques.To clarify its material properties,the spectral properties of this material a

Raman spectroscopy has been widely used in pharmaceutical analysis due to its remarkable characteristics such as avoiding the interference of water in samples,simplicity of sample pretreatment,rapid nondestructive analysis,and gre

Millions of people are affected by eye diseases which can affect the shape and dimensions of the whole eye.For examination of ocular accommodation and pathological changes caused by these diseases,high resolution imaging of the wh
