Investigations on full-Heusler alloys MnTaAl and MnWAl for spintronic and thermoelectric applications.

Half-metallic materials are widely used as spintronic devices such as electrodes, magnetic tunneling junction, and giant magnetoresistance. In this work, we have systematically investigated the structural stability, Gilbert damping, electronic structure, and magnetism together with exchange interactions and Curie temperatures for MnTaAl and MnWAl alloys. Initially, we estimate their structural stability and offer possible phase synthesis.

[Effects of Management Measures on Soil Water-soluble Carbon and Nitrogen and Their Three-Dimensional Fluorescence Characteristics of Plantations on Loess Plateau].

The plantation on the Loess Plateau was selected as the research site to study the changes of soil water-soluble carbon and nitrogen content and components of soil dissolved organic matter (SDOM) under different management measures (litter removal, young forest, shrubs, grassland). The uncleared plantation was used as the control. Results show that the soil water-soluble organic carbon content of shrubs and young forests was significantly higher than that in other management measures.

[Histologic characteristics of in vitro constructed skin basement membrane].

Objective: To observe the histological characteristics of constructed basement membrane in tissue-engineered skin.

Methods: Forskins from circumcision in normal children were obtained with informed consent of the parents, and then the epidermal keratinocytes (KC) and dermal fibroblasts (Fb) were isolated with trypsin and collagenase D digestion in sequence. Tissue engineered skin with composite chitosan was maintained in a submerged state for 3 days, and then at the air-liquid interface.
