The synthesis of covalent carbon nitride films becomes an important subject in the materials research *** a new synthetic method two low-energy(400 and 1000eV)nitrogen ion beams are used to bombard on C_(60) thin films *** bombarded films are used for Raman and x-ray photoelectron spectroscopy(XPS)*** results of the analyses show that under the bombardment of 400eV nitrogen ion beam,the film still contains a large amount of undestructed C_(60) *** the case of l000eV bombardment,only a little amount of C_(60) molecules is kept *** experimental results also show that the destructed carbon species will combine chemically with nitrogen ions to form stable covalent carbon nitride,confirmed by the Raman peaks of,e.g.,*** XPS Nls and Cls lines also indicate the formation of covalent carbon nitride in the bombarded films.

近年来膀胱癌的治疗在世界范围内取得了很大进展,包括传统的手术切除、化疗和放疗以及免疫治疗,然而其潜在的分子机制和关键途径仍不清楚。随着基因测序技术的进步,长链非编码RNA(lncRNA)已被证明以不同的分子机制在多种肿瘤组织中显示致癌基因的作用。竞争性内源RNA(ceRNA)假说是一种RNA之间相互作用的新机制,具有微小RNA(miRNA)的结合位点的lncRNA,可行使miRNA海绵作用吸附于miRNA,进而解除miRNA对其靶基因的抑制作用,升高靶基因的表达水平。本文就lncRNA作为ceRNA参与膀胱癌进展的研究进展做一综述。

Photoactive complexes of nonprecious transition metals, mainly including those in the first-row and partially the second-row of the Periodic table of elements, have received increasing attention in view of their low cost and long-term sustainability. They are recognized as promising alternatives to noble transition metal complex congeners that have been extensively studied in optoelectronic devices, artificial photosynthesis, photocatalysis, biodiagnostics, and therapeutics, etc. This review is devoted to a comprehensive summary on the classical and recent advances on photoactive nonprecious transition metal complexes, including photoactive Zr, V, Cr, Mo, and W complexes, Mn complexes and hybrids, Fe, Co, Ni, and Cu complexes, and Zn and Cd complexes and hybrids. A particular focus is given on the molecular design, modulation of photophysical and photochemical properties, and applications of the representative and lately-developed nonprecious metal complexes. In addition, a perspective on the future development in this field is provided at the end of this review.
