Insights into cork weathering regarding colour, chemical and cellular changes i...

A comprehensive analysis of outdoor weathering and soil burial of cork during 1-year experi- ments was carried out with measurements of CIELAB color parameters, cellular observa- tions by scanning electron microscopy, and surface chemical features analysed by ATR- FTIR and wet chemical analysis. Cork applied in outdoor conditions above and below ground retained its physical structure and integrity without signs...

Cork Façades as an Innovative and Sustainable Approach in Architecture: A Revie...

Façades give the first impression of a structure, reflecting the overall aesthetic appeal, archi- tectural styles, cultural influences, and technological advancements. Emphasis on sustainability is increasing, with a shift towards eco-friendly and energy-saving materials, triggered by decreasing the environmental impact of construction. Cork is a green competitive material for various engineering and design app...

Chemical composition, morphology, antioxidant, and fuel properties of pine nut ...

Pine nut shells are waste lignocellulosic residues from the production of edible pine nut kernels that are generally only used for energy production by combustion. Lignocellulosic feedstocks, such as pine nut shells, may be valorized namely by their integration into biorefinery schemes. This article set out to analyze the chemical composition, morphology, antioxidant, and fuel properties of pine nut shells from...

Cuticular Waxes and Cutin in Terminalia catappa Leaves from the Equatorial São ...

This study presents for the first time an analysis of the content and chemical composition of the cuticular waxes and cutin in the leaves of the widespread and important tropical species Terminalia catappa. The leaves were collected in the equatorial Atlantic islands of São Tomé and Príncipe, in the Gulf of Guinea. The epicuticular and intracuticular waxes were determined via dichloromethane extraction and thei...

Biochemical Characterization and Fuel Properties of Endemic Taurus Flowering As...

Taurus flowering ash (Fraxinus ornus subsp. cilicica) is an endemic tree species in Turkey. The bark of the species was characterized for summative chemical composition, the monomeric composition of polysaccharides, phenolic content, in vitro and ex vivo antioxidant properties of hydrophilic extracts, the composition of lipophilic extractives and suberin, and thermal degradation. The bark has an elevated ash co...

Population dynamics of Bursaphelenchus xylophilus associated with pine forest d...

The pinewood nematode (PWN), Bursaphelenchus xylophilus, is a quarantine organism in the European Union and the causal agent of pine wilt disease (PWD), a serious threat to pine forests worldwide, leading to rapid decline and death. In Europe, this invasive pest was first reported in Portugal in 1999, on Pinus pinaster. Due to its economic importance and worldwide distribution, an enormous effort has been devot...

Optimization of autohydrolysis of olive pomaces to obtain bioactive oligosaccha...

The valorisation of agro-industrial residues presents a challenge in obtaining economically sustainable and environmentally friendly industrial processes. Olive pomace is a by-product generated in large quantities, from olive oil extraction. This residue mostly consists of lignocellulosic materials. The aim of this study was to evaluate the potential use of extracted olive pomaces (EOP) obtained from olives wit...

The Influence of Solvent and Extraction Time on Yield and Chemical Selectivity ...

The cuticular lipid compounds, usually named cuticular waxes, present in the cuticular layering of Quercus suber adult leaves were extracted with solvents of different polarities (n-hexane, dichloromethane and acetone) and analysed by GC–MS. Q. suber leaves have a substantial cuticular wax layer (2.8% of leaf mass and 239 g/cm2), composed predominantly by terpenes (43–63% of all compounds), followed by aliphati...

Phytochemical Composition of Extractives in the Inner Cork Layer of Cork Oaks w...

The beetle Coraebus undatus, during its larval stage feeds, and excavates galleries on the cork-generating layer of Quercus suber L. trees, seriously affecting the cork quality with significant economic losses for the cork industry. This work compared the composition of the extracts present in the innermost cork layers (the belly) of cork planks from Q. suber trees with low and moderate C. undatus attack in one...
