Opis:: The electrocatalytic reduction of carbon dioxide into valued chemicals such as formic acid has the most promising potential in applying renewable energy for useful materials and mitigating the greenhouse effect. However, the studies still focus on developing catalysts with low price and high catalytic properties. In this study, nitrogen atoms were decorated into carbon structure by a unique ultrasonic method, then the nitrogen-doped carbon material was applied as catalyst in CO₂ reduction, it exhibited excellent electrochemical activity, 4 times higher than the normal method. The improved activity should be attributed to the interaction between nitrogen and carbon atoms through analysis.

Opis:: By h(G,x) and P(G,λ) we denote the adjoint polynomial and the chromatic polynomial of graph G, respectively. A new invariant of graph G, which is the fourth character R₄(G), is given in this paper. Using the properties of the adjoint polynomials, the adjoint equivalence class of graph $B_{n-6,1,2}$ is determined, which can be regarded as the continuance of the paper written by Wang et al. [J. Wang, R. Liu, C. Ye and Q. Huang, A complete solution to the chromatic equivalence class of graph $\overline{B_{n-7,1,3}}$, Discrete Math. (2007), doi: 10.1016/j.disc.2007.07.030]. According to the relations between h(G,x) and P(G,λ), we also simultaneously determine the chromatic equivalence class of $\overline{B_{n-6,1,2}}$ that is the complement of $B_{n-6,1,2}$.

Opis:: Insulin is an important peptide hormone for the glucose metabolism. The structural flexibility of insulin B chain attracts a lot of our attention for understanding the biological activity. Our work carried out the extensive sampling to statistically clarify the structural changes of isolated $T_{6}$ human insulin B chain. We introduced the Landau free energy to describe the isolated insulin B chain whose experimental structure locates a local energy minimum. Its trained model was subjected to thousands of heating and cooling circles between the high and low temperatures. Six typical structure clusters were found by classifying the final generated structures with RMSD and radius of gyration. The structures in clusters indicate the potential deformations of insulin B chain at residues 5-8 of N-terminus, residues 9-12 of central helix and residues 24-29 of C-terminus, which agrees with the experimental results.
