Recent investigations have revealed that, in addition to monolignols, some phenolic compounds derived from the flavonoid and hydroxystilbene biosynthetic pathways can also function as true lignin monomers in some plants. In this study, we found that the hydroxystilbene glucosides isorhapontin...

The present study evaluates biosorption efficiencies of pesticides atrazine, fluazifop-P-butyl, lactofen, lambda-cyhalothrin and chloropyrifos on corks of Quercus cerris and Quercus suber trees. The studies were carried out in batch and effects of pH (3, 7 and 9), temperature (10, 20, 30 and 40°C), ...

Heavy metals adsorption with lignocellulosic materials has been heavily researched in the last years. Since heat activation has been used with good results to increase the adsorption capacity of some materials, heat-treated wood might be a better adsorbent. This hypothesis is the basis of the...

Sustainable use is essential to guarantee future availability of wood. Structural and chemical mapping can contribute to fit-for-purpose usage, as accurate and detailed knowledge of the material enables guided utilization and optimal performance of wood. The platform presented in this paper,...

Agonandra brasiliensis, ivory wood, is a tree species from the Brazilian cerrado with a bark featuring a thick cork layer. The present study aimed to describe the cellular features and chemical composition of this cork. The cork was investigated regarding cellular structure and biometry, as well as ...

Wood-based panels made of waste and recycled raw material are lacking of dimensional stability. The aim of this study is to evaluate the potential beneficial effect of heat treatment (HT) on the properties of particleboards produced from waste of Pinus sp. used for packaging. The wood particles...

The heat treatment of wood (i.e. torrefaction) followed by densification of wood particles (e.g. by briquetting) may be used as a process to improve homogeneity and energy properties of wood for use as a solid fuel. The wood of Eucalyptus grandis and Eucalyptus spp. were treated at 180, 200 and...

The structure of lignin and suberin, and ferulic acid (FA) content in cork from Quercus suber L. were studied. Extractive-free cork (Cork), suberin, desuberized cork (Cork_sap), and milled-cork lignins (MCL) from Cork and Cork_sap were isolated. Suberin composition was determined by GC-MS/FID,...

Cork is a natural cellular material with a rather unique set of properties, and its best known application is as stopper for wine bottles. The cork tissue contains structural discontinuities, for example, lenticular channels (LCh), that influence the in-use performance of cork products. X-ray...

Single-layered particleboards were produced from granulated Quercus cerris bark containing cork and phloem granules using standard hot-press equipment and phenol-formaldehyde resin. The experimental boards were tested for thickness swelling, mechanical strength and thermal properties. Scanning...
