We present a general methodology to pattern functional materials on the nanometer scale using self-assembled molecular templates on conducting substrates. A soft lithographic gas phase edge patterning process using poly(dimethylsiloxane) molds was employed to form electrically isolating organosilane patterns of a few nanometer thickness and a line width that could be tuned by varying the time of deposition. Electrodeposition was employed to deposit patterns of Ni and ZnO on these prepatterned substrates. Deposition occurred only on patches of the substrate where no organosilane monolayer was present. The process is simple, inexpensive, and scalable to large areas. We achieved formation of metallic and oxide material patterns with a lateral resolution of 80 nm. 相似文献

It is well known that real functions whose Fourier transform vanishes around the origin must have many sign changes. We show
that a similar phenomenon occurs for real Paley–Wiener functions whose Fourier transform is “smoother” at the origin than
elsewhere. We also show that if the Fourier transform of a function is “less smooth” in a neighborhood of the origin than
elsewhere, then the function cannot have too many real zeros. 相似文献

A method of the atomic-emission spectrum analysis of soil has been developed for control of the accumulation of technogenic
impurities in environmental objects. A sample, after calcination at 550°C, is evaporated in an arc discharge. Spectra are
recorded by a DFS-8 spectrograph. Simultaneously, determination is made of Li, Ba, Sr, Cu, Zn, Cr, Ni, Co, Pb, Bi, Mo, V,
Ge, Ga, Y, Nb, Sn, Cd. For the majority of the elements the detection limits are lower than their percent abundance in the
crust and their maximum permissible concentrations.

A simple and accessible method for the production of glassy specimens from aqueous concentrates based on saccharose is proposed.
During the process of such a specimen preparation an additional concentration of impurities takes place. These saccharose
specimens were used for the X-ray fluorescence determination of Se in waste water with crystallization preconcentration.

PbZr0.53Ti0.47O3 (PZT) thin films containing nanoparticles of Pt (3–10 nm) were produced using pulsed laser deposition (PLD). The Pt content can be tuned by varying the energy density of the laser beam. Phase and microstructure analysis of the thin films was performed using XRD, SEM, TEM and AFM. The electrical properties were investigated by C–V and I–V measurements. The effective dielectric constant of the composite films increased substantially through the Pt dispersion. These films are promising candidates, for instance, for high-density dynamic random access memory (DRAM) devices. PACS 77.22.Ch; 77.84.Lf; 81.15.Fg 相似文献
