Journal ArticleDOI
How and why does willow biochar increase a clay soil water retention capacity
TL;DR: In this article, the internal porosity of willow biochar was quantitatively and qualitatively characterized using X-ray tomography, 3D image analysis and Helium ion microscopy.
Journal ArticleDOI
Quantitative characterization of pore structure of several biochars with 3D imaging
TL;DR: In this paper, X-ray computed microtomography was used to image biochars at resolution of 1.14 $\mu$m and the obtained images were analyzed for porosity, pore-size distribution, specific surface area and structural anisotropy.
Journal ArticleDOI
Effects of pyrolysis temperature on the hydrologically relevant porosity of willow biochar
TL;DR: In this paper, the x-ray tomography images of willow dried at 60°C and biochar samples pyrolysed in three different temperatures (peak temperatures 308, 384, 489°C, heating rate 2'°C'min−1).
Journal ArticleDOI
Quantitative characterization of pore structure of several biochars with 3D imaging
TL;DR: Structural anisotopy analysis showed that used raw material considerably affects the pore characteristics at micrometre scale, and attention should be paid to raw material selection and quality in applications requiring optimized pore structure.
Journal ArticleDOI
Atomic Structure of a Spinel-Like Transition Al2O3(100) Surface
Thomas N. Jensen,Kristoffer Meinander,Stig Helveg,Adam S. Foster,Sampo Kulju,Tiziana Musso,Jeppe V. Lauritsen +6 more
TL;DR: The transition alumina films are crystalline and perfectly stable in ambient atmospheres, a quality which is expected to open the door to new fundamental studies of the surfaces of transition aluminas.
