CO2-driven cation leaching after tropical forest clearing.
MARKEWITZ, D. - FIGUEIREDO, R. de O. - DAVIDSON, E. A.

Formato:	Artigo em periódico indexado (ALICE)
Enlaces:	The objective of this study was to investigate the role of dissolved CO2 (H2CO3*) as a mechanism of cation removal from surface soils under secondary land uses in the tropics. Soil leachate columns were prepared with 0?10 cm soils from…

THE IMPLEMENTATION OF FINDINGS PUBLISHED IN SCHOLARLY ARTICLES
Hubbe, Martin A.

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion
Enlaces:	Articles published in scholarly journals, such as this one, tend to be mainly addressed to researchers at universities. Industrial follow-up and implementation of results from a scholarly article appears to be the exception, rather than the rule. Research grant specifications,…

CHARACTERISTICS OF CORN STALK HEMICELLULOSE PYROLYSIS IN A TUBULAR REACTOR
Lv, Gao-Jin - Wu, Shu-Bin - Lou, Rui

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion
Enlaces:	Pyrolysis characteristics of corn stalk hemicellulose were investigated in a tubular reactor at different temperatures, with focus mainly on the releasing profiles and forming behaviors of pyrolysis products (gas, char, and tar). The products obtained were further identified using various…

BACTERIAL CELLULOSE REINFORCED THERMOPLASTIC COMPOSITES: PRELIMINARY EVALUATION OF FABRICATION AND PERFORMANCE
Gu, Ruijun - Kokta, Bohuslav V. - Frankenfeld, Katrin - Schlufter, Kerstin

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion
Enlaces:	Mechanical properties of polyethylene (PE) composites were evaluated as a function of the addition of bacterial cellulose (BC). It was found that BC could improve the mechanical properties of the composites with or without the combination of traditional wood fiber.…

ROUGHNESS OF ESTERIFIED EASTERN COTTONWOOD
Farahani, Mohammad Reza M. - Taghizadeh, Fatemeh

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion
Enlaces:	The aim of this study was to investigate the effect of esterification via acetic or propionic anhydride on the surface roughness of eastern cottonwood. Eastern cottonwood (Populous deltoides) was esterified by using acetic or propionic anhydride without using any solvent…

REMOVAL OF ACID-SOLUBLE LIGNIN FROM BIOMASS EXTRACTS USING AMBERLITE XAD-4 RESIN
Schwartz, Thomas James - Lawoko, Martin

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion
Enlaces:	This paper describes a method for the removal of acid-soluble lignin from acid hydrolyzed hemicelluloses extracted from a mixture of northern hardwood chips, by using Amberlite XAD-4 resin, which was shown to remove 100% of furan derivatives and 90% of…

PRODUCTION OF SINGLE CELL PROTEIN, ESSENTIAL AMINO ACIDS, AND XYLANASE BY PENICILLIUM JANTHINELLUM
Rao, Mala B. - Varma, A. J. - Deshmukh, Sumedha S.

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion
Enlaces:	Microbial biomass having 46% crude protein content and enriched with essential amino acids as well as extracellular xylanase activity (100-150 IU/ml) was produced by an efficient fungal strain, Penicillium janthinellum (NCIM St-F-3b). Optimization studies for maximum xylanase and biomass production…

DETERMINATION OF CORN STALK FIBERS’ STRENGTH THROUGH MODELING OF THE MECHANICAL PROPERTIES OF ITS COMPOSITES
Rodriguez, Manuel - Rodriguez, Alejandro - Bayer R., Jordi - Vilaseca, Fabiola - Girones, Jordi - Mutje, Pere

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion
Enlaces:	Worldwide cultivation of corn is expanding, due in part to the increasing production of bioethanol. In consequence, huge amounts of corn stalks residues are been produced. Instead of incineration, we transformed the corn stalks into a semichemical pulp and successfully…
