Coppice management is an ecologically important silvicultural practice to provide the quicker and higher potential of wood biomass production for industrial demands. Understanding morphological anatomical responses coppiced trees could help determine quantity quality thus better tree plantations short-time production. However, there a little investigation in adaptation different fast-growing sp...
Given the widespread use of wood-based materials and that these are often damaged, an abundance have been developed to repair restore wood. Most treat binder filler as a single system; however, there is yet be system has all desired properties ideal wood-repair composite. Aiming for goal creating wood filler, this study proposed composite combined epoxy resins, polyether amines, poplar fibers. ...
quebracho tannin wood adhesive in non formaldehyde approach has low autocondensation rate and needs more press time than formaldehyde-based wood adhesives to produce wood composites. in this study, boric acid was used to increase autocondensation rate of quebracho tannin adhesive to make poplar plywood. the main ingredients of the adhesives include quebracho tannin, naoh, hexamine, boric acid a...
Eugenol in water nanoemulsions loaded with tebuconazole appear as a very promising alternative formulations for wood protection against xylophagous fungi that are the main species responsible different rots structures. The dispersions prepared and upon dilution (impregnation mixtures) were characterized by apparent hydrodynamic diameter distribution of oil droplets their long-term stability. im...
This paper examines the potential for phytoremediation of MTBE, a gasoline additive that has become a prevalent and persistent groundwater pollutant, due to its' non-sorbing and non-reactive nature in water. A novel experimental design is developed to measure plant uptake and transpiration of MTBE from hydroponic systems, separating these processes from passive volatilization of the chemical. P...
