Ingår i: JOURNAL OF PHYSICS-CONDENSED MATTER. - : IOP PUBLISHING LTD. - 0953-8984. ; 7:36, s. 7173-7184
-
Tidskriftsartikel (refereegranskat)abstract
- We study the influence of surface roughness on the infrared reststrahlen band in insulating materials. We model the surface features with either truncated spherical bumps on, or truncated spherical pits in, the substrate. The polarizability of the truncat

Recension (övrigt vetenskapligt/konstnärligt)abstract
- Electronic and Li ionic conduction in sputtered transparent ZrO2 thin films intercalated with Li ions, have been studied using impedance spectroscopy, isothermal transient ionic current and galvanostatic intermittent titration measurements. The ZrO2 was f

Ingår i: JOURNAL OF APPLIED PHYSICS. - : AMER INST PHYSICS. - 0021-8979. ; 89:5, s. 3012-3017
-
Tidskriftsartikel (refereegranskat)abstract
- The oxidation kinetics of nickel particles with an approximate median size of 15 nm was determined by thermogravimetry. The particles had a thin initial oxide shell amounting to 36 wt % of the sample. The kinetics was studied in pure oxygen in the tempera

Ingår i: NANOTECHNOLOGY. - : IOP PUBLISHING LTD. - 0957-4484. ; 10:1, s. 25-28
-
Tidskriftsartikel (refereegranskat)abstract
- A new model for particle growth can predict the well known lognormal particle size distribution from first principles in a physically realistic way. The model is completely different from the usually applied coagulation models; it is based on a reside

-
Tidskriftsartikel (refereegranskat)abstract
- In modern nanoparticle production methods, such as inert-gas evaporation, a strong effort is made to avoid coagulation of particles. Therefore, the classical coagulation models are not suitable for predicting the particle size distribution. This paper

Tidskriftsartikel (refereegranskat)abstract
- Films of Ce-Zr oxide were made by sol-gel deposition according to three different routes. Cyclic voltammetry showed that Li+ intercalation/deintercalation took place if the Ce content was sufficient. The films had a high transmittance for visible ligh
