The Near Field Properties of Colloidal Polystyrene Microspheres on Silicon

Abstract

We have investigated the optical resonance and near field inside and under absorptive polystyrene (PS) microspheres on Si wafers. Near field flat plane images of PS microspheres were numerically simulated. Nanostructures were prepared on Si substrates using the regular two dimensional (2D) arrays by a single pulsed laser irradiation (KrF, lambda = 248 nm). Periodical PS nanoparticle, PS nanoflowers and Si nanobumps were fabricated by different laser fluence. Mechanisms for PS particle size reduction and Si nanobump formation by laser irradiation were discussed on the base of the theoretical calculations. Good agreement between theoretical calculations and experimental results has been observed.

Post-Crosslinked Poly(<I>meta</I>-divinylbenzene) and Its Adsorption to Phenol from Aqueous Solutions

“…[1][2][3][4][5][6][7][8][9][10][11][12] In 1970's, Davankov et al prepared a types of novel hypercrosslinked polymers (HCPs) using a post-crosslinking method, 13 14 and these HCPs exhibit high Brunauer-Emmett-Teller (BET) surface area and unique pore structure, 15 16 which lead to excellent adsorption to aromatic compounds. Unfortunately, the synthetic procedure for the HCPs are confronted with some problems; the most serious one is utilization of the recognized carcinogen chloromethyl methyl ether (CMME) in the Friedel-Crafts reaction, which presents problems both in the production process and field application.…”

Superresolution observed from evanescent waves transmitted through nano-corrugated metallic films

“…We should take into account that Eqs. (16)(17)(18)(19)(20)(21)(22) have been obtained in the , x z plane assuming that the sum of the components of the wave vector in the object plane is in the x direction. Similar equations will be obtained for any , x z plane (in case the sum of the wave vector components in the object plane is in the x direction)…”
