Neighbor Sum Distinguishing Total Colorings of Graphs with Bounded Maximum Average Degree

引用

Acta Mathematica Sinica,English Series 2014年第4期30卷 703-709页

作者： Ai Jun DONG Guang Hui WANG School of Science Shandong Jiao Tong University School of Mathematics Shandong University

A proper [h]-total coloring c of a graph G is a proper total coloring c of G using colors of the set [h] ={1, 2,..., h}. Let w（u） denote the sum of the color on a vertex u and colors on all the edges incident to u. For each edge uv ∈ E（G）, if w（u） ≠ w（v）, then we say the coloring c distinguishes adjacent vertices by sum and call it a neighbor sum distinguishing [h]-total coloring of G. By tndi∑ （G）, we denote the smallest value h in such a coloring of G. In this paper, we obtain that G is a graph with at least two vertices, if mad（G）〈 3, then tndi∑ （G） ≤k ＋ 2 where k = max{△（G）, 5}. It partially confirms the conjecture proposed by Pilgniak and Wolniak.

Confirmation on origin of primary electron in solid state cathodoluminescence

引用

Chinese Physics B 2010年第6期19卷 548-550页

作者：黄金昭李世帅冯秀鹏王培吉张仲 School of Science University of Jinan

This paper utilizes the brightness-voltage waveform curve to investigate the primary electron in solid state cathodoluminescence. The results indicate that the primary electron is from the interface state of SiO2/MEH-PPV （Poly[2- methoxy-5-（2-ethylhexyloxy）-1,4-phenylenevinylene]） under the lower electric field which contributes to the 580-nm emission. With increasing the electric field, the 405-nm emission is obtained, and under this condition, the origin of the primary electron is mainly from tunneling.

White-light emission of ZnO nanoparticles prepared by sol-gel method

引用

Chinese Physics B 2011年第12期20卷 341-345页

作者：李世帅张仲黄金昭冯秀鹏刘如喜 School of Physical Science University of Jinan

In：ZnO nanoparticles are prepared by the sol-gel process. The ratios of In/（Zn＋In） are 0%, 5%, 8%, 10%, and 15%, respectively. Crystal phase structures and optoelectronic properties of these samples are characterized and the chromaticity coordinates of different samples are also calculated in CIE-XYZ colour system. The results show that preferred growth direction of ZnO changes from （002） plane to （001） plane and interplanar distance becomes shorter. When the doping amount of In is 5%, Zn atoms are completely replaced by In atoms. The resistivities of the samples first decrease, then increase afterwards with the increase of the amount of In. With the increase of In, the ultraviolet emission is redshifted and new peaks occur at 465 nm, 535 nm, and 630 nm. The sample with 10% indium has white-light emission. The band structures of samples with 0% and 12.5% indium are investigated by the first principle method. The mechanism of white emission is discussed from the viewpoint of additional energy levels.

Maintaining the stemness of the transplanted stem cell spheroids in an inflammatory microenvironment is challenging but important in regenerative medicine. Direct delivery of stem cells to repair periodontal defects may yield suboptimal effects due to the complexity of the periodontal inflammatory environment. Herein, stem cell spheroid is encapsulated by interfacial assembly of metal-phenolic network(MPN) nanofilm to form a stem cell microsphere capsule. Specifically, periodontal ligament stem cells(PDLSCs) spheroid was coated with FeⅢ/tannic acid coordination network to obtain spheroid@[FeⅢ-TA] microcapsules. The formed biodegradable MPN biointerface acted as a cytoprotective barrier and exhibited antioxidative, antibacterial and anti-inflammatory activities, effectively remodeling the inflammatory microenvironment and maintaining the stemness of PDLSCs. The stem cell microencapsulation proposed in this study can be applied to multiple stem cells with various functional metal ion/polyphenol coordination, providing a simple yet efficient delivery strategy for stem cell stemness maintenance in an inflammatory environment toward a better therapeutic outcome.
