Capacitive deionization (CDI) is a promising electrosorption technique for removing the salt ions from brackish water by applying an electrical potential across two electrodes. Ordered mesoporous carbon with suitable pore size, good cross-linked porous structure and high surface area, is considered to be a promising electrode material. In this work, manganese oxide nanoparticles decorated ordered mesoporous carbon were synthesized via an impregnation method. The nitrogen sorption analysis and TEM results show that the structure of carbon host is maintained well after manganese oxides loading. However, the majority pore-size and the specific surface area of the hybrids decrease with the increasing of loading amount, indicating the successful entrance of the guest manganese oxide nanoparticles into the mesoporous carbon channels. The influences of the heat-treatment and the guest loading amount on the phases of the manganese oxides were also investigated. The electrosorption performance was investigated in a CDI batch. Compared with the pristine ordered mesoporous carbon, the electrochemical and electrosorption performances of the hybrids are importantly improved. Particularly, the hybrids with 15 wt% Mn heat-treated at 400 • C exhibit the best specific capacitance (83.9 F/g) in 1 mol/L NaCl electrolyte, electrosorption capacity (5.4 mg/g) under an applied potential of 1.2 V.

Background and Objective. To investigate the significance of edaravone (EDA) combined with emotion management model in promoting the recovery process and improving negative psychology in patients with type 2 diabetes mellitus (T2DM) combined with cerebral stroke (CS). Methods. Eighty-one patients with T2DM combined with CS who attended our hospital and received rehabilitation treatment from March 2020 to May 2021 were enrolled to a prospective nonrandomized controlled analysis. Among them, 46 patients received EDA combined with emotional management model and were regarded as the observation group (OG), and 35 received EDA combined with conventional care and were seen as the control group (CG). The clinical efficacy and glycemic function of the two groups were compared, and the scores of the Activities of Daily Living (ADL), Pittsburgh Sleep Quality Index (PSQI), and Self-Assessment Scale for Anxiety and Depression (SAS and SDS) were investigated before and after treatment. At the time of discharge, patient satisfaction with care was counted. Within six months after prognosis, T2DM self-management behavior and CS self-management behavior score surveys were conducted. Results. There was no difference in clinical efficacy between both groups ( P > 0.05 ); The posttreatment glucose, PSQI, SAS, and SDS scores were lower in the OG than in the CG, while ADL and emotional management scores were higher than in the CG ( P < 0.05 ). In addition, both nursing satisfaction and prognosis disease self-management behavior scores were also higher in the OG than in the CG ( P < 0.05 ). Conclusion. The EDA combined with emotion management model can effectively promote the recovery process of patients with type II T2DM combined with CS, while improving their negative psychology and enhancing their self-management ability, which has high potential for clinical application.

Dehmer et al. [Interrelations of graph distance measures based on topological indices, PLoS One 9 (2014) e94985] explored the graph measures based on some topological indices and demonstrated some useful properties of them. In this work, we survey the graph measures based on the Balaban index of a graph, and prove some extremal properties on them for several classes of graphs. Moreover, through numerical calculation and comparison, we find the graph measures based on Balaban index of a graph behave better than that based on Randić index in some special cases.
