Triana C, Araujo C, Ahuja R, Niklasson G, Edvinsson T
Sci Rep . 2017 May; 7(1):2044. PMID: 28515466
Solid state materials with crystalline order have been well-known and characterized for almost a century while the description of disordered materials still bears significant challenges. Among these are the atomic...

Johansson M, Kristiansen P, Duda L, Niklasson G, Osterlund L
J Phys Condens Matter . 2016 Sep; 28(47):475802. PMID: 27660919
Nanocrystalline tungsten trioxide (WO3) thin films prepared by DC magnetron sputtering have been studied using soft x-ray spectroscopy and optical spectrophotometry. Resonant inelastic x-ray scattering (RIXS) measurements reveal band gap...

Topalian Z, Niklasson G, Granqvist C, Osterlund L
ACS Appl Mater Interfaces . 2011 Dec; 4(2):672-9. PMID: 22204641
Photoinduced SO(2) fixation on anatase TiO(2) films was studied by in situ Fourier transform infrared (FTIR) and X-ray photoelectron spectroscopy (XPS). The TiO(2) films were prepared by reactive DC magnetron...

Nettelblad B, Niklasson G
J Phys Condens Matter . 2011 Dec; 8(38):7049-58. PMID: 22146672
We propose a new approximative relation for the low-frequency dielectric permittivity of liquid-filled porous materials. In this formulation, effects of microgeometry are included through the so-called [Formula: see text] parameter....

Andersson A, Niklasson G, Granqvist C
Appl Opt . 2010 May; 26(11):2164-70. PMID: 20489838
We study thermochromism in fiber composites with a view to their possible use for controlling the transmission of luminous and solar radiation. Spectrophotometric measurements of collimated and total transmittance were...

Eriksson T, Hjortsberg A, Niklasson G, Granqvist C
Appl Opt . 2010 Mar; 20(15):2742-6. PMID: 20333029
The dielectric function epsilon identical with epsilon(1) + iepsilon(2) has been determined for Al(2)O(3) films prepared by electron beam evaporation, in the 5-50-microm wavelength range. The data were extracted from...

Niklasson G, Granqvist C, Hunderi O
Appl Opt . 2010 Mar; 20(1):26-30. PMID: 20309062
The Maxwell Garnett and Bruggeman effective medium theories are derived for the average dielectric permeability of heterogeneous materials from a unified theoretical approach. It starts by specifying two random unit...

Tesfamichael T, Hoel A, Niklasson G, Wackelgard E, Gunde M, Orel Z
Appl Opt . 2008 Mar; 40(10):1672-81. PMID: 18357163
We propose a novel, to our knowledge, method for characterizing the optical properties of pigment particles or powders. Measurements of the diffuse and the total transmittance as well as the...

Vargas W, Niklasson G
Appl Opt . 2008 Mar; 40(1):85-94. PMID: 18356976
Solar reflectance spectra of pigmented coatings have been obtained from spectroscopic measurements involving integrating sphere attachments. We demonstrate that measured and computed reflectances of an extended four-flux model [Appl. Opt....
