A collection of shape-controlled Pt nanoparticles has been prepared using two different and previously described methodologies, both using oleylamine/oleic acid as capping material/solvent. A new decontamination protocol is presented to effectively clean the surface of the different nanoparticles thus allowing a full exposure of their surface area and consequently to make the most of their surf...

fe3o4-containing cotton-like mesoporous silica system (fe3o4@ncsm) was studied with regard to its performance towards the photodecolorization of bromothymol blue (btb) aqueous solution. the surface properties of the functionalized catalyst were analyzed by a series of characterization techniques like ftir, xrd, bet, sem and tem. the n2 adsorption–desorption analysis shows that the mesostructure...

Microstructure freeform surface is a type of freeform surfaces which is widely used in optical-mechanical-electronic components with increasing high precision requirement. This paper presents the characterization of structured freeform surfaces based on a pattern matching analysis method. The method employed rough matching by micro-structure features and then precise matching based on least squ...

Various analytical methods based on the real reciprocity relation are applied to the problem of Rayleigh wave scattering by a surface crack. In one formulation, the reflection coefficient observed at the transducer terminals is expressed in terms of an integral over the crack surface of the product of the perturbed and unperturbed fields. This integral is then converted to a volume integral and...

The sea surface is an important background of sea surface targets and its infrared radiation characterization is the basis of infrared detection and recognition of sea surface targets. The model of linear wave theory and JONSWAP spectrum was used to achieve shape and display of ocean wave. Real-time infrared characterization simulation model was established for the sea surface, considering the ...
