High-Performance Visible to Mid-Infrared Photodetectors Based on HgTe Colloidal Quantum Dots under Room Temperature.

HgTe colloidal quantum dots (CQDs) are one of few materials that can realize near-to-midwave infrared photodetection. And the quality of HgTe CQD directly affects the performance of photodetection. In this work, we optimize the method of synthesizing HgTe CQDs to reduce the defect concentration, therefore improving the photoelectric properties.

[The endocrine function of the skeleton].

Skeleton has long been recognized as a organ supporting body system and regulating metabolism of calcium and phosphorus. Recent researches found that bone cells, especially osteoblast and osteoclast, synthesize and secrete various bioactive molecules, such as bone morphogenetic proteins, growth factors, adipokines, inflammatory cytokines and cardiovascular bioactive peptides. The active factors produced by bone not only play important roles in the skeleton system per se by paracrine/autocrine pathway but also regulate energy metabolism, inflammatory process, endocrine homeostasis by endocrine pathway.
