Laser-Powered Homogeneous Pyrolysis (LPHP) of Lignin Dispersed into Gas Phase

open access: yesMolecules
The gas-phase delivery of lignin into the hot zone of cw-CO2 laser-powered homogeneous pyrolysis (LPHP) reactor under “wall-less” conditions led to the breakdown of lignin macromolecules into neutral oligomers and paramagnetic fragments deposited onto ...

Impacts of Organic Structures and Inherent Minerals of Coal on Soot Formation during Pyrolysis

open access: yesEnergies, 2019
The pyrolysis of four pairs of raw and acid-washed coals under N2 atmosphere was carried out in a drop tube reactor at 1250 °C. The results show that both organic structures and metal elements have an important influence on the formation of soot ...

Spectral albedos of midlatitude snowpacks [PDF]

open access: yes
Spectral albedos of impure-nonhomogeneous snowpacks, typical of midlatitudes, from 400 to 2200 nm were modeled through a numerical solution of the radiative transfer equation in the two-stream approximation.

Carbon deposition model for oxygen-hydrocarbon combustion. Task 6: Data analysis and formulation of an empirical model [PDF]

open access: yes
The formation and deposition of carbon (soot) was studied in the Carbon Deposition Model for Oxygen-Hydrocarbon Combustion Program. An empirical, 1-D model for predicting soot formation and deposition in LO2/hydrocarbon gas generators/preburners was ...

Ultra-ductile and low friction epoxy matrix composites

open access: yes, 2015
We present the results of an effective reinforcement of epoxy resin matrix with fullerene carbon soot. The optimal carbon soot addition of 1 wt. % results in a toughness improvement of almost 20 times.
