Studying carbonisation with raman spectroscopy [PDF]

open access: yes, 2013
Raman spectroscopy can provide fast and non-destructive analysis of carbonaceous materials. As it is able to detect nanometre-sized structural features, Raman spectroscopy is widely used in the study of carbon nanotubes, fullerenes, graphenes, and many ...

Fast pyrolysis of lignin-coated radiata pine

open access: yesJournal of Analytical and Applied Pyrolysis, 2015
Abstract A new coating preparative method of the Pinus radiata feedstock was used to process a mixture of Acetocell lignin and sawdust prepared at different mass ratios of lignin to sawdust, 1:18 (LI 20 ) and 1:7 (LI 40 ) to overcome feeding issues into a fluidized bed pyrolysis reactor.

Structural studies of a fucogalactoxyloglucan from pinus radiata primary cell walls : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Biochemistry at Massey University [PDF]

open access: yes, 1980
1. The changes in carbohydrate composition of elongating Pinus radiata primary cell walls were investigated. In the hemicellulose B extracts, a large increase in the percentage of non-starch, non-cellulosic, glucose was found to occur on cessation of ...

Forest rotation lengths under carbon sequestration payments [PDF]

open access: yes
Carbon dioxide emissions resulting from direct human activities, primarily fossil fuel use and land clearing, have altered the global carbon cycle. Carbon is absorbed (sequestered) by plant matter during photosynthesis, so that approximately 50% of the ...
