The first attempt to transform the basic strategy of this natural process for use in human craftsmanship was the ancient lacquer method. The sap of the lacquer tree (Rhus verniciflua) contains large amounts of a phenol (urushiol), a polysaccharide and the enzyme laccase. This oil-in-water emulsion solidifies in the presence of oxygen. The Chinese began using this phenomenon for the production of highly creative artwork more than 6,000 years ago. It was the first example of an isolated enzyme being used as a catalyst to create an artificial plastic compound. In order to apply this process to the production of products on an industrial scale, an inexpensive phenol must be used, which is transferred by an enzyme to active radicals that react with different components to form a compounded material. At present, the following approaches have been studied: (1) In situ polymerization of lignin for the production of particle boards. Adhesive cure is based on the oxidative polymerization of lignin using phenoloxidases (laccase) as radical donors. This lignin-based bio-adhesive can be applied under conventional pressing conditions. The resulting particle boards meet German performance standards. By this process, 80% of the petrochemical binders in the wood-composite industry can be replaced by materials from renewable resources. (2) Enzymatic copolymerization of lignin and alkenes. In the presence of organic hydroperoxides, laccase catalyses the reaction between lignin and olefins. Derailed studies on the reaction between lignin and acrylate monomers showed that chemo-enzymatic copolymerization offers the possibility to produce defined lignin-acrylate copolymers. The system allows control of the molecular weights of the products in a way that has not been possible with chemical catalysts. This is a novel attempt to enzymatically induce grafting of polymeric side chains onto the lignin backbone, and it enables the utilization of lignin as part of new engineering materials. (3) Enzymatic activation of the middle-lamella lignin of wood fibers for the production of wood composites. The incubation of wood fibers with a phenol oxidizing enzyme results in oxidative activation of the lignin crust on the fiber surface. When such fibers are pressed together, boards are obtained which meet the German standards for medium-density fiber boards (MDF). The fibers are bound together in a way that comes close to that by which wood fibers are bound together in naturally grown wood. This process will, for the first time, yield wood composites that are produced solely from naturally grown products without any addition of resins."],["dc.identifier.isi","000168842900001"],["dc.identifier.pmid","11398916"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/25281"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Springer"],["dc.relation.issn","1432-0614"],["dc.relation.issn","0175-7598"],["dc.title","Modification of lignin for the production of new compounded materials"],["dc.type","review"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Therefore, small specimens were cut from H. campechianum stems from plantations in the lowlands of the Usumacinta delta in Mexico. The latter were subjected to laboratory decay and moisture studies. Water vapour sorption, liquid water uptake, and swelling of H. campechianum appeared much lower in comparison with most European grown wood species and similar to tropical hardwoods such as Tectona grandis . After removal of water-soluble ingredients, water vapour sorption of H. campechianum specimens further decreased, which assigned such ingredients a somewhat hydrophilic character. Mean mass losses (ML) due to decay by white, brown, and soft rot fungi in laboratory tests were <5%. On the basis of a dose-response model, wetting ability factors and ML values from decay tests predicted an outdoor performance similar to T. grandis and Intsia bijuga . Based on this preliminary property profile, H. campechianum can be recommended for both outdoor (e.g. fencing, outdoor decking, railing) and indoor applications (e.g. flooring, manufacturing of furniture, wall and ceiling panels, decoration artwork)."],["dc.identifier.doi","10.1515/hf-2021-0187"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/106106"],["dc.language.iso","en"],["dc.notes.intern","DOI-Import GROB-530"],["dc.relation.eissn","1437-434X"],["dc.relation.issn","0018-3830"],["dc.title","Properties of Mexican bloodwood ( Haematoxylum campechianum L.).

The plywood production process consisted of two steps: firstly impregnation and curing of the veneers, and secondly assembly of the panel. The adhesive used was a phenolic resin. The values obtained for shear strength were above the standard limit of rejection (1 N mm(-2)), and therefore the samples met the European requirements of plywood designed for exterior conditions. The phenolic resin improved its adhesive ability when the samples were heated for 72h at 95 degrees C. The highest shear strength for modified wood was 3.97 +/- .45 N mm(-2) at 0.8 M, 3.39 +/- 0.26 N mm(-2) at 1.3 M, and 2.35 +/- 0.23 N mm(-2) at 2.3 M, for Betula sp., Fagus sp., and Piceo sp., respectively. The samples constructed with unmodified veneers presented higher shear strengths and higher cohesive wood failures than the samples constructed with modified veneers. The possible effect of the two-steps production of the plywood is discussed. The delamination test of DMDHEU-modified Betula sp. and Fagus sp. plywood showed no open glue lines, while the samples of Picea sp. treated with the higher concentration of DMDHEU suffered delamination.

The adhesion performance of DAC adhesives was investigated using tensile shear strength measurements according to European standard EN302-1. Results showed the DO and the concentration of DACs had a predominant impact on the adhesion performance. The optimal formulation of DAC adhesives was found to be the aqueous solutions of DAC with a DO of 1.75 and a concentration of 40 wt %. The corresponding best bonding performance was represented by the bonding strength of about 9.53 MPa for beech wood specimens and 5.75 MPa for spruce wood specimens. Furthermore, wood specimens in shear strength tests mainly revealed a substrate failure mode rather than adhesive or cohesive failure. This indicates that the DAC adhesives possessed a stronger bonding strength than the wood itself.
