Calcium phosphates are a family of compounds with different chemical compositions, structures and properties containing calcium ions and functional groups of orthophosphate （ pO34- ）, metaphosphate （ PO3- ） or pyrophosphate （ P2O4-7 ） and sometimes hydrogen or hydroxide ions. Calcium phosphates can be widely found in nature as well as in hard tissues （bone and tooth） of the vertebrate. Owing to similar chemical composition and structure to the main inorganic constituents of bone and tooth, calcium phosphate-based materials are promising biomaterials with high biocompatibility, and have been investigated for applications in various biomedical areas. Calcium silicate-based materials have attracted much attention on their potential applications in various biomedical fields such as bone de- fect repair and drug delivery. In recent years, this research group has been focusing on the research in this exciting and rapidly evolving research field, and has published many papers. This article will provide a brief review on our main research work on the synthesis, characterization, properties and applications of nanostructured materials of calcium phosphates and calcium silicates. Finally, future perspectives and challenges for the research and applica- tions of nanostructured materials of calcium phosphates and calcium silicates are discussed.

Traditional researches on metal corrosion under salt solutions deposit conditions are usually carried out by visual, electron microscopic observations and simple electrochemical measurement via a traditional one-piece electrode. These techniques have difficulties in measuring localized corrosion that frequently occur in inhomogeneous media. This paper reports the results from the experiments using specially shaped coupons and a relatively new method of measuring heterogeneous electrochemical processes, namely, the wire beam electrode（WBE）. Preliminary results from copper and aluminum corrosion in highly concentrated sodium chloride solutions with and without solid deposits show that the method is useful in simulating and studying corrosion especially localized corrosion in pipelines.

Multicolor fluorescent probes based on small organic molecules have the advantages of low cost, good biocompatibility, easily modifiable molecular structures and adjustable fluorescence performance. In addition, small molecule multicolor fluorescent probes generally undergo multi-site or multi-step reactions, which means that they can be used for the specific detection of structurally similar substances in complex bio-systems. In this review, we focus on the design and application of multicolor fluorescent probes based on small organic molecules: single fluorophores with multiple reaction sites, multiple fluorophores with single reaction sites, or multiple fluorophores with multiple reaction sites. Moreover, a design strategy for multicolor fluorescent probes and its application in biological imaging are also summarized, providing a systematic plan for future research on fluorescent probes functionalized by small organic molecules. It will also play an important role in the development of additional functions for small organic molecule fluorescent probes.
