From cubane-assembled Mn-oxo clusters to monodispersed manganese oxide colloidal nanocrystals.

The assemblies of [MO] (M = metal) cubanes represent a fascinating class of materials for a variety of application fields. Although such a structural characteristic is relatively common in small molecules and in extended bulk solids, high nuclearity clusters composed of multiple [MO] units as their backbones are rare. In this work, we report two new Mn-oxo clusters, Mn Mn O(OOCMe)(OMe)(py) ([Mn-Ac]) and Mn Mn O(OOCCMe)(OMe)(MeOH)(py) ([Mn-Piv]), whose core structures are assemblies of either 6- or 7-cubanes in different packing patterns, which have been unambiguously revealed by single crystal X-ray diffraction technique.

Nanotubular FeO and MnO with hierarchical porosity as high-performance anode materials for lithium-ion batteries.

Developing eco-friendly and low-cost advanced anode materials, such as FeO and MnO, is fundamental to improve the electrochemical performance of lithium-ion batteries (LIBs). The rational engineering of the microstructure of FeO and MnO to endow it with one-dimensionally and hierarchically porous architecture is a feasible way to further improve and optimize the electrochemical performance of the anode materials. Herein, we demonstrate a facile strategy to prepare nanotubular FeO and MnO as advanced anode materials for high-performance LIBs.

[In silico cloning of Efp-0, a novel earthworm fibrinolytic enzyme gene and verification of its coding region by RT-PCR].

There are four different types of N-terminal amino acid sequences (F-I-0, F-I, F-II, F-III) in the multicomponents of earthworm fibrinolytic enzymes (EFE). In GenBank 21 nucleic acid sequences of EFE have been reported. Among them, most of the N-terminal amino acid sequences belong to the F-III type,few belong to the F-II type.
