Effects on density, shrinking, color changing and chemical surface analysis through FTIR of Tectona grandis thermo-treated: Density, shrinking, color changing and chemical analysis by FTIR of the thermally-treated teak wood
(Forest Sciences, 2016)
Thermal-treatment wood is used as an option to improve durability of wood in recent years. This study
evaluated the effect of temperature in thermally treated Tectona grandis wood in density, shrinking, color
changing ...
Biopulp from pineapple leaf fiber produced by colonization with two white-rot fungi: Trametes versicolor and Pleurotus ostreatus
(BioResources, 2016)
Trametes versicolor and Pleurotus ostreatus were used for the biopulping from pineapple leaf fiber (PALF). PALF substrate was subjected to T. versicolor for 2 to 6 weeks and to P. ostreatus for 4 to 8 weeks. The yields, ...
Torrefacción del aserrín de cinco tipos de maderas de Costa Rica para aumentar el contenido energético (Documento I)
(Instituto Tecnológico de Costa Rica. Vicerrectoría de Investigación y Extensión (VIE). Escuela de Ingeniería Forestal. Centro de Investigación en Innovación Forestal (CIF), 2017)
La torrefacción de biomasa consiste en someter el material a temperaturas que varían entre 200°C a 300°C, en ausencia de oxigeno por periodos que varían de 5 a 35 minutos. Durante esas condiciones la biomasa pierde una ...
Madheras II: tecnología de la madera de seis especies nativas de rápido crecimiento con potencial para la reforestación comercial en Costa Rica (Documento I)

Reducing warp and checking in 4 by 4 beams from small-diameter tropical species (tectona grandis, gmelina arborea, and cordia alliodora) obtained by turning the pith inside out.
(Forest Products Society, 2015)
Small-diameter logs from plantation trees are prone to warp and to produce checks due to the presence of juvenile wood, growth stresses, and asymmetric shrinkage during the drying process. In the present study, we analyzed ...
Evaluation of biodeterioration and the dynamic modulus of elasticity of wood in ten fast-growing tropical species in costa rica exposed to field testing
(Statny Drevarsky Vyskumny Ustav, 2015)
In tropical regions, it is possible to produce a large variety of timber species in plantation conditions. However, wood from these trees has low natural durability. Biodeterioration and the dynamic modulus of elasticity ...
