It is proposed that melt-extrusion of poly(3-hydroxybutyrate-co-3hydroxyvalerate) at varying processing temperatures and screw speeds causes changes in the atomic positioning of the oxygen atoms in the helix structure due to torsion of the main chain bonds. By wide angle X-ray scattering it was obse

PHB-depolymerase degraded poly[(3-hydroxybutyric acid)-co-(3-hydroxyvaleric acid)] (PHB/V) significantly. No other enzyme used in this study showed activity toward PHB/V. Weight loss and gel permeation chromatography (GPC) studies suggested that enzymatic degradation takes place by a surface erosion
## Abstract Carbon nanofibers (CNFs) are grown by catalytic CO disproportionation over ultrafine Fe~3~O~4~ catalyst at a hydrogen concentration of 0β29.17%, and the timeβdepending rates of CNFs growth are continuously monitored and the morphologies of the asβsynthesized CNFs are analyzed. Increasin
