按照《中国菌物学会团体标准管理办法》(菌物发字2018[1]号),由中国菌物学会组织,吉林农业大学、食药用菌教育部工程研究中心、山西临县农业农村局、山西菇隆农牧业发展有限公司等单位联合起草的团体标准《临县枣木香菇Linxian jujube wood Lentinula edodes》已完成社会面征集意见公示,并通过专家审定,现予以发布为本会团体标准,标准编号为《临县枣木香菇Linxian juj...
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...
Background and Objectives: It is important to understand the temporal and spatial distributions of standing wood carbon storage in forests to maintain ecological balance and forest dynamics. Such info...
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...
2023年10月18日下午,英国国家科研与创新署(UKRI)国际主任Frances Wood女士、中国处主任博大力博士(Daniel Brooker)等一行五人到中国科学院遗传与发育生物学研究所访问“中国科学院-英国约翰英纳斯中心植物和微生物科学联合研究中心(CAS-JIC Centre of Excellence for Plant and Microbial Science, CEPAMS)”...
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...
Slash pine (Pinus elliottii) is the most important and a fast-growing material that is used for industrial timber and pulp production. A breeding program of slash pine that aims to improve wood proper...
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...
Reliable estimates of tree growth and wood yield are fundamental to support the management of restored forests and better reconcile the objectives of recovering biodiversity with the provision of ecos...
