A new species of Odontobdella Oka, 1923 (Erpobdelliformes: Salifidae), a macrophagous terrestrial leech from Central China.

This paper describes a new species of macrophagous terrestrial leech distributed in Wuling Mountain area in Central China. On the basis of morphological and structural observation, mitochondrial cytochrome c oxidase subunit I (COI) gene sequence analysis and phylogenetic tree inference, this leech was identified as a new species of the genus Odontobdella in the family Salifidae, and named Odontobdella gaowangjiensis sp. nov.

Tailoring the cell morphology and characteristics of poly(lactic acid) foams via a stereocomplex crystallization-assisted phase separation strategy.

Stereocomplex (SC) crystallization between poly(l-lactide) (PLLA) and its enantiomer poly(d-lactide) (PDLA) provides an effective approach to enhancing the physicochemical properties of poly(lactic acid) (PLA). In this study, we systematically investigate the effects of SC crystallization on the thermal-induced phase separation (TIPS) behavior of PLA enantiomers/1, 4-dioxane solutions, as well as the microstructure, pore morphology, and properties of the resulting PLA foams. The results show that increasing PDLA content leads to a higher relative fraction of SC crystallites and alters the cell morphology, transitioning from fishbone-like tubular pores to irregular small pores formed by densely packed submicron particles.
