Journal ArticleDOI
Accuracy versus speed in fluctuation-enhanced sensing
TL;DR: In this paper, the relationship between the measurement time window and the statistical error of the measurement data in the simplest case, when the output is the mean-square value of the stochastic signal, was studied.
Journal ArticleDOI
Laser-induced synthesis of nanostructured thin films
TL;DR: In this article, the authors present a number of important characteristics of laser techniques for preparation of nanostructured thin films with foci on laser ablation (LA) and laser-assisted chemical vapor decomposition (LCVD).
Journal ArticleDOI
Chromogenics for Sustainable Energy: Some Advances in Thermochromics and Electrochromics
TL;DR: In this article, the limitations of thermochromic VO2 films for energy efficient fenestration and showed from calculations that nanocomposites containing VO2 can have superior properties and display high luminous transmittance and large temperature-dependent solar transmittances modulation.
Journal ArticleDOI
Low-frequency current noise in electrochromic devices
TL;DR: In this article, 1/f noise was observed in electrochromic (EC) devices capable of modulating their optical transmittance by an applied voltage, and the power spectral density Si at fixed frequency varied as Si~I2.

TL;DR: In this article, Tungsten-oxide-based thin films were prepared by reactive DC magnetron sputtering in the presence of oxygen and nitrogen, and the results showed that up to 4 at.% of nitrogen were as transparent as undoped tungsten oxide films and displayed enhanced electrochromic properties manifested in an increase in the coloration efficiency.
