چکیده
Direct transformation of solar energy into electrical by means biological photosynthesis is considered as an attractive option for sustainable production. Thylakoid membranes, the site photosynthesis, are regarded a promising material development photoelectric biodevices, which produce power consuming only light oxygen evolves at photobioanode upon irradiation and biocathode converts it back to water. Therefore, in this work dual-feature based on nanoimprinted gold substrates modified with thylakoids combination capacitive part made planar substrate coated conductive polymer was designed evaluated, providing open-circuit potential ?0.21 V vs. Ag|AgCl|KClsat capacitance ca. 60 F m?2 both ambient artificial illumination 400 W m?2. Combination thylakoid bilirubin oxidase transparent indium tin oxide resulted biosupercapacitor remarkable characteristics light, viz. voltage high 0.74 V, stable charge-discharge cycles during 2 h.

For example, by arranging nano dots consisting of a magnetic material, logical circuits can be designed whi...
متن کاملNanoimprint Lithography
The Nanoimprint lithography (NIL) is a novel method of fabricating micro/nanometer scale patterns with low cost, high throughput and high resolution (Chou et al., 1996). Unlike traditionally optical lithographic approaches, which create pattern through the use of photons or electrons to modify the chemical and physical properties of the resist, NIL relies on direct mechanical deformation of the...

Nanoimprint lithography (NIL) is a fabrication technology that offers high-throughput, ultrahigh resolution patterning at great cost savings compared to most competing next-generation radiative lithography methods. As a result of its rapid development in the past decade and its potential for sub-100 nm lithography, NIL has been listed by MIT’s Technology Review as one of ten emerging technologi...
متن کاملNanoimprint lithography for nanodevice fabrication
Nanoimprint lithography (NIL) is a compelling technique for low cost nanoscale device fabrication. The precise and repeatable replication of nanoscale patterns from a single high resolution patterning step makes the NIL technique much more versatile than other expensive techniques such as e-beam or even helium ion beam lithography. Furthermore, the use of mechanical deformation during the NIL p...
