Spectroscopic analysis of carbonization behavior of wood, cellulose and lignin
TL;DR: The surface and bulk chemistry of Japanese cedar (Cryptomeria Japonica), cotton cellulose and lignin samples carbonized at 500-1,000 °C was investigated by elemental analysis, Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopic (XPS) and micro-Raman spectrometry as mentioned in this paper.

Microstructure of wood charcoal prepared by flash heating
TL;DR: In this paper, the formation mechanism of the microstructure in wood carbonized by the flash heating process seems to originate from fragmented and oxygen-containing pyrolysis compounds in contrast to conventional heating.

Diamond and pore structure observed in wood charcoal
Kengo Ishimaru,Tomas Vystavel,Paul Bronsveld,Toshimitsu Hata,Yuji Imamura,Jeff Th. M. De Hosson +5 more
TL;DR: In this paper, various carbon structures were observed in the wood charcoal sample: pyrolytic graphite layers, onion-like particles, and diamond structure, and the pore structure was observed by electron microscopy, and it was supposed that the microstructure and pores are closely related.
Microstructural study of carbonized wood after cell wall sectioning
TL;DR: In this paper, the inner planes of Japanese cedar cell walls were analyzed by transmission electron microscopy (TEM) and μ-Raman spectroscopy, and the predominant structure was of a turbostratic nature.

Catalytic Graphitization of Wood‐Based Carbons with Alumina by Pulse Current Heating
Toshimitsu Hata,Kengo Ishimaru,Masashi Fujisawa,Paulus Bronsveld,Tomas Vystavel,J.T.M. de Hosson,H. Kikuchi,T. Nishizawa,Yuji Imamura +8 more
TL;DR: A pulse current heating method was used for a 5min carbonization step under a pressure of 50MPa in order to promote graphitization at temperatures between 2000 and 2200°C as mentioned in this paper.
