The trunk bark of Tabebuia caraiba Bignoniaceae was found to contain four novel iridoids, 6-O-E-p-coumaroyljioglutin D (2), 6-O-E-p-coumaroyl-3-demethyl-3-O-ethyljioglutin D (3), 6-O-E-p-coumaroyl-1-demethyl-1-O-ethyljioglutin D (4), 7-O-E-p-coumaroyljiofuranaldehyde (5), three known iridoids,...

Biomass residues and waste can be converted into bioliquids by pyrolysis, which can contribute to both the production of renewable fuels and the recycling of waste. In this paper, the catalytic co-pyrolysis of mixtures of beech wood (BW) and polyamide-6 (PA6) in different ratios was investigated to ...

An in-depth understanding of the bonding mechanism of botanical concrete (BC) can facilitate its development and improve its performance. For this purpose, six hot-pressed BC samples comprising mixtures of wood with concrete powder, carbonated concrete, and sand were prepared in this study. The...

This research investigated the effect of different lignocellulosic fiber sizes and additives on the durability of wood plastic composites (WPCs) after water absorption/desorption. WPCs were prepared by blending wood flour (20, 80, 120 mesh) with polypropylene (PP). Polypropylene grafted maleic...

In order to explore the effect of high temperature heat-treatment on the machining properties of Pinus massoniana wood, the experiment were conducted on evaluating machining performance of masson pine wood untreated and treated at different temperatures according to LY/T 2054-2012 "Method for...

Production of particleboards is associated with volatile organic compounds emissions, many of which have odorous properties. The objective is to determine whether the odor emissions from the production, using spruce and aspen as raw material, comply with the local odor limit defined in a specific...

lkali solution immersion is widely used as a pretreatment process during bamboo and wood product manufacturing. In this study, a surface analysis on bamboo chips pre-treated with sodium hydroxide (NaOH) at room temperature was performed. The influence of this treatment on the bamboo surface color,...

Unbleached screen reject (USR) is a byproduct widely available from the kraft pulping that is rich in cellulose and requires a sustainable destination. Therefore, the purpose of this work was to determine the best condition to apply USR as reinforcement of cement-bonded fiber boards (CBFBs); using...

In this study, the interactions between a phenol-formaldehyde resorcinol (PRF) adhesive and water-extractable wood constituents were investigated using combined in-situ FTIR spectroscopy and rheology analysis for a simultaneous examination of the progress of chemical reactions and coherent changes...

A new catalyst modified by plasma was investigated to substantively improve the photoactivity of TiO₂ for formaldehyde abatement. Pure anatase TiO₂ mechanically mixed with biochar was fabricated by H₂ plasma (denoted as C/TiO₂) under low temperatures (<397 K). C/TiO₂ exhibited a high and...
