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.

Advanced Sustainable Systems, Volume 9, Issue 12, December 2025.Biobased bamboo shavings are used to immobilize Lewis base catalysts for CO2 valorization. Two methods are investigated for immobilization of catalysts: covalent isocyanate coupling and silane condensation. The isocyanate method achieves 100% conversion of cyclic carbonate starting from epoxides, whereas the silane method yields glycerol carbonate with

An inventory of Guadua (Guadua angustifolia) bamboo in the Coffee Region of Colombia
European Journal of Forest Research, 2006 Management of renewable natural resources and the corresponding policy formulation should be founded on reliable data and information. This refers both to information on the resource itself and to information on the market situation. In this paper, we present methodology and major results of an inventory of the Guadua resources, in a study area of ...

Spermatophyta Molecular Clock: Time Drift and Recent Acceleration
Plant-Environment Interactions, Volume 6, Issue 5, October 2025.Exponential increase in the base substitution rate in recent geologic time. ABSTRACT Angiospermae radiation is widely recognized as a mid‐Cretaceous event, but the adaptive radiation of Asarum and Viola as spring ephemerals also occurred during the Quaternary. To better understand the evolution of Angiospermae through geological time, a robust and well‐
