Journal ArticleDOI
Infrared-transparent convection shields for radiative cooling: Initial results on corrugated polyethylene foils
TL;DR: In this paper, the authors investigated a design with crossed layers of vee-corrugated high-density polyethylene foils, which achieved infrared transmittance up to 73% and thermal resistance of 1.1 m 2 K W −1 (determined with a modified guarded hot-plate technique).
Journal ArticleDOI
Analysis of an Attenuator Artifact in an Experimental Attack by Gunn–Allison–Abbott Against the Kirchhoff-Law–Johnson-Noise (KLJN) Secure Key Exchange System
Laszlo B. Kish,Zoltan Gingl,Robert Mingesz,Gergely Vadai,Janusz Smulko,Claes-Göran Granqvist +5 more
TL;DR: In this article, the authors argued that the Kirchhoff-law-Johnson-noise (KLJN) secure key exchange system could experience a se se (e.g.
Journal ArticleDOI
Preparation of thin films and nanostructured coatings for clean tech applications: A primer
TL;DR: In this paper, the major preparation technologies and their characteristics for thin films and nanostructured coatings are surveyed and discussed in detail, and perspectives are given on possible future developments.
Journal ArticleDOI
Electron transport and recombination in dye sensitized solar cells fabricated from obliquely sputter deposited and thermally annealed TiO2 films
S.M. Waita,Bernard O. Aduda,Julius M. Mwabora,Claes-Göran Granqvist,Sten-Eric Lindquist,Gunnar A. Niklasson,Anders Hagfeldt,Gerrit Boschloo +7 more
TL;DR: In this article, annealed titanium dioxide films prepared by oblique reactive DC magnetron sputtering were studied using intensity-modulated photocurrent and photovoltage spectroscopy.
Proceedings ArticleDOI
Electroactive polymers in large area chromogenics
TL;DR: In this paper, the basic physics of electrochromism in electroactive polymers, also named conductive polymers; point out the requirements for use of electrophoresis in electrochromic devices (which includes displays, smart windows and electrooptical modulators); and describe some of the materials and processing aspects that are of particular relevance with reference to thin film technology.
