We attempted to use tobiko powder, a byproduct of the konjac cake production, to rear the 5th-instar silkworms by mixing it in the artificial diet, and found that tobiko powder was usable up to the mixing ratio of 20 wt%. Even when the content of mul

We attempted to use the keratin resin as a crystallizable adhesive agent serving as the binder for the milled wood fillers to develop a totally bio-based wood filler-feather keratin resin composite (WKC). The milled feathers could be resinified easil

Herein, the anesthetization of Bombyx mori silkworms via the water narcosis treatment by soaking in room-temperature water for 1 h was found effective in keeping the tensile strength of its forcibly spun silk filament comparable to that of naturally

Injection-molding was performed using ethylene–propylene copolymer as the matrix by varying the physicochemical treatment of the reinforcement, i.e., core portion of kenaf stem that was dry-distilled and coated with or without β-sheet protein deri

Forcibly spinning method has once shown a potential to enhance tensile strength of Bombyx mori silkworm silk fibers to the level of spider dragline silk. Thus, the tensile data for the forcibly spun silk fibers reported so far were compared with the

Injection molding was performed using poly(l-lactide) (PLLA) as a matrix and by varying the reinforcements, i.e., dry-distilled kenaf core (D-core) or untreated kenaf bast fibers, and the physical properties for these composites were subsequently com
