Biomass is becoming particularly important as a starting material for advanced carbon structures. In this study, we found interesting nanostructures on the surface of burnt spaghetti using scanning electron microscopy, transmission electron microscop

We present results from neutron-imaging studies of slow, vacuum pyrolysis of beech, poplar and conifer wood, and pelletized biomass from room temperature up to 1000 °C. A detailed and quantitative method to extract 2D (in situ neutron radiography, N

Hydrogen is an element of fundamental importance for energy but hard to quantify in bulk materials. Neutron radiography was used to map in situ loss of elemental hydrogen from beech tree wood samples during pyrolysis. The samples consisted of three w

Raman spectroscopy is performed to disclose struchiral properties of porous carbon samples including lignocellulosic biomass. Analysis of spectral statures of carbon, around 1350 cm"1 and 1580 cm"1, indicates higher porosity for the biomass sample.

We report results from experiments where we characterize the surface properties of soot particles interacting with high-pressure methane. We find considerable differences in behavior of the soot material between static and dynamic pressure conditions

In-situ wide-angle X-ray scattering (WAXS) measurements have been conducted on atmospheric-pressure fuel-rich premixed freely propagating ethylene/oxygen flames with argon and nitrogen dilution. In this work, a novel analysis methodology able to prov

The mean size of flame-formed fluorescent carbonaceous nanoparticles was detected by in-situ time-resolved fluorescence anisotropy (TRFA) measurements. A long investigated coflowing laminar diffusion flame of ethylene was used as combustion system fo

Carbon particle structures containing only a few graphene layers have been collected from a Bunsen (propane) diffusion flame in the low particle concentration pale yellow luminous regions close to the soot inception. These particles were sampled dire

The dynamics of particle formation were investigated for a diffusion-like ethylene flame containing a cooling metal plate on which particles condensed. Small-angle and wide-angle X-ray scattering techniques were combined to follow size- and structura
