the current methods for treatment of cancers are inadequate and more specific methods such as gene therapy are in progress. among different vehicles, cationic liposomes are frequently used for delivery of genetic material. this investigation aims to prepare and optimize dotap cationic liposomes containing an antisense oligonuclotide (asodn) against protein kinase c alpha in non-small cells lung...

a humidity sensor thin film based on nanoporous pbwo4-wo3 composites has been prepared by spin coating technique with different weight ratio of pbwo4 (pb) and wo3 (wo) (pwwo-01, pwwo-82, pwwo-64, pwwo-46, pwwo-28, pwwo-01) and their humidity sensing properties have also been investigated at different relative humidity (rh) in the range of 5% - 98% at room temperature with dc resistance. it is f...

in this paper, zno thin film is deposited on slide glass substrate using the sol-gel process. presenting well-defined orientation of zno thin films nanostructure were obtained by dip coating of zinc acetate dihydrate, monoethanolamine (mea), de-ionized water and isopropanol alcohol. the annealed zno thin films were transparent ca 85-90% in visible range with an absorption edges at about 375 nm....

the surface and interfacial analysis of silicon oxide film on silicon substrate is particularly crucial in the nano-electronic devices. for this purpose, series of experiments have been demonstrated to grow oxide film on si (111) substrate. then these films have been used to study the structure of the film by using x-ray photo emission spectroscopy (xps) technique. the obtained results indicate...

The development of thin film-based structures/devices often requires thin films to be transferred onto arbitrary substrates/surfaces. Controllable and non-destructive transfer method, although highly desired, remains quite challenging. Here we report a general method for fabrication and transfer of hybrid (ultra)thin films. The proposed solution-based in-situ transfer method shows not only its ...

The relaxation behaviors of thin polymer films show a strong dependence on temperature and film thickness. Direct quantitative detection of the relaxation behaviors of thin polymer films at nanometer scale by traditional instruments is however challenging. In this study, we employed atomic force microscopy (AFM)-based force-distance curve to study the relaxation dynamics and the film thickness ...

Due to the good photocatalytic activity, the TiO2@CNTs thin film is highly desirable to apply to the self-cleaning glass for green intelligent building. Here, the TiO2@CNTs thin film has been successfully achieved by polymer-assisted approach of an aqueous chemical solution method. The polymer, polyethylenimine, aims to combine the Ti4+ with CNTs for film formation of TiO2@CNTs. The resultant t...

This paper reports the correlation between film thickness, nanostructure and DC electrical properties of copper thin films deposited by PVD method on glass substrate. X-ray diffraction (XRD) and atomic force microscopy (AFM) were used for crystallography and morphology investigation, respectively. Resistivity was measured by four point probe instrument, while a Hall effects measurement system w...
