Low-viscosity UV-curable?resins?are widely used in industry as they allow for UV curing materials with reduced amounts of reactive diluents to adjust the viscosity. But their?mechanical properties?and...
The simultaneous attainment of high strength and high toughness of transparent cellulose nanofibril (CNF) film can expedite its uses in advanced applications. In this work, a wood-inspired strategy is...
Rosin is renewable biomass with the potential to enhance wood properties. However, its high leaching rate restricts the durability of rosin impregnation. To immobilize rosin in wood structure, polymer...
Resole resins have many applications, especially for foam production. However, the use of phenol, a key ingredient in resoles, has serious environmental and economic disadvantages. In this work, ligni...
In this paper, a novel epoxy flame retardant PPDEG-EP (P-E) was synthesized from eugenol by nucleophilic substitution reaction and Prilezhaev epoxidation. The chemical structure was identified by nucl...
Schima superbais a precious broadleaf tree species that produces excellent timber. Analyzing the radial variation of wood anatomical properties within stems and determining the boundary between the ju...
Background:Wood basic density (WBD) is one of the most crucial wood property in tree and mainly determined the end use of wood for industry. However, the measurement WBD is time- and cost-consuming, w...
In current technology, polymers reinforced with ultra-fine strands of carbon fibers represent a class of composite materials that are "as light as a feather and as strong as steel," leading to versati...
The initial introduction of Pinus elliottii (PEE) to China occurred in the 1930s, and the planting of this conifer species has now attained close to 3 million ha in the subtropical zone of southern Ch...
The incorporation of polymers derived from renewable resources is more desirable in the preparation of wood composites due to its sustainability. As biomass feedstock, rosin has been used for the prep...
Secondary organic aerosol (SOA) formation during photo-oxidation of primary emissions from cookstoves used in developing countries may make important contributions to their climate and air quality imp...
The use of bioenergy for district heating is usually seasonal with a high consumption during the cold periods. Therefore some type of the harvested material storage is necessary. Woody materials are u...
The present study examines the macrostructure and density of larch wood and possible influences on the productivity of larch stands. The studies were conducted in the middle and sub-tundra taiga in th...
After spruce, the Scots pine (Pinus sylvestris Linnaeus) is the second most important commercial coniferous tree species in the Czech Republic. However, we are finding out that awareness of the varia...
Knowledge of forest parameters, such as wood volume, is required for a sustainable forest management. Collecting such information in the field is laborious and even not feasible in inaccessible areas....
