A facile method for the synthesis of silver-silica（Ag-SiO2） Janus particles with functionalities suitable for textile applications is reported.Silica nanoparticles prepared by the Stober method were functionalized with epoxy,amine,and thiol groups,which were confirmed by Fourier transform infrared analysis.The functionalized silica nanoparticles were used to produce Pickering emulsions,and the exposed surface was used for the attachment of silver nanoparticles（AgNPs） via the low-temperature chemical reduction method.The morphology and structure of the Ag-SiO2 Janus particles were characterized by scanning electron microscopy,scanning transmission electron microscopy,high-resolution transmission electron microscopy,energy-dispersive X-ray analysis,and UV-vis spectroscopy.Because of their specific functionalities,these Ag-SiO2 Janus particles are proposed for applications on textile substrates,as they can overcome several drawbacks of direct application of AgNPs on textiles,such as leaching,agglomeration,and instability during storage. 相似文献

ON THE SPECIFIC EXPRESSION OF BIT-LEVEL ARITHMETIC CODING 总被引：1，自引：0，他引：1
Arithmetic coding is a relatively new loss-less data compression technique that has attracted much attention in recent years. We show the iteration of bit-level arithmetic coding can be specified by a continuous function. The analysis expression and some properties of this function are discussed. An application of the function is provided for exploring the security of arithmetic codes when they are used for data encryption. 相似文献

It is classically known that a real cubic surface in cannot have more than one solitary point (or -singularity, locally given by x
2 + y
2 + z
2 = 0) whereas it can have up to four nodes (or -singularity, locally given by x
2 + y
2 − z
2 = 0). We show that on any surface of degree d ≥ 3 in the maximum possible number of solitary points is strictly smaller than the maximum possible number of nodes. Conversely,
we adapt a construction of Chmutov to obtain surfaces with many solitary points by using a refined version of Brusotti’s Theorem.
Combining lower and upper bounds, we deduce: , where denotes the maximum possible number of solitary points on a real surface of degree d in . Finally, we adapt this construction to get real algebraic surfaces in with many singular points of type for all k ≥ 1.
