Fast pyrolysis of Guadua angustifolia-Kunth

Energy Procedia, 2017
Abstract In this work, the condensable gases of the bio-oil produced from its fast pyrolysis at 500 oC for 30 s has been analyzed by Py-GC/MS. Relatively high yields of acetic acid, phenolics and levoglucosan have been found. Levoglucosan can be used as a source for synthesizing bio-fuels and both, phenolics and levoglucosan in the production of ...

Development of a perforated panel for acoustic conditioning based on Colombian guadua fiber (Guadua angustifolia Kunth) [PDF]

TECCIENCIA, 2019
The present research is about the practical implementation of a perforated panel for acoustic conditioning, manufactured with guadua, a typical Colombian fiber. The developed panel is checked for its acoustic conditioning properties. Guadua is an attractive natural resource with great potential for renovation and use in sustainable construction.

Bolted join strength under parallel to grain double shear in guadua angustifolia structures

Tecnura, 2014
In a bolted joint of structures that use Guadua angustifolia as the main supporting material, the resistance to the double metal shears paralleled to fiber could be influenced by an extensive list of parameters including parallel to fiber crushing ...

Comparison of the structure and flexural properties of Moso, Guadua and Tre Gai bamboo [PDF]

, 2015
Bamboo is an underutilized resource widely available in countries with rapidly developing economies. Structural bamboo products, analogous to wood products, allow flexibility in the shape and dimensions of bamboo structural members.

Quality and Conservation of Riparian Forest in a Mountain Subtropical Basin of Argentina

International Journal of Ecology, Volume 2016, Issue 1, 2016., 2016
The aims of this work were to describe the conservation status of riparian forests located in a mountain subtropical basin of Tucumán province, Argentina, and assess how the quality of riparian forests is related with altitude, plant species richness, proportion of exotic species, and Total Suspended Solids (TSS) in adjacent rivers.

Vibrational and Compositional Analysis Associated with the Color of Guadua angustifolia Kunth Variety Bicolor (GAKVB)

Advances in Materials Science and Engineering, Volume 2014, Issue 1, 2014., 2014
The vibrational modes and compositional behavior of plant material of Guadua angustifolia Kunth Variety Bicolor (GAKVB) and the characteristics associated with color changes were evaluated by Raman, infrared, and energy‐dispersive X‐ray spectroscopy. In the vibrational spectra, the frequencies of 1598, 2099, and 845 cm−1 were associated with yellow and
