Evacuation planning with flood inundation as inputs

Recent flooding events happening in our city demonstrate frequency and severity of floods in the UK, highlighting the need to plan and prepare, and efficiently defend. Different from the numerous evacuation model and optimization algorithms, this paper aims to address flood evacuation planning with flood inundation as inputs. A dynamic flooding model and prediction to estimate the development of both surface water and flooding from rivers and watercourses has been fed into evacuation planning at various levels. A three-step approach is proposed. The first step is to identify assembly point designation. The second step is to find the candidate shortest path from each assembly point to all safe areas for all evacuees with consideration of possible inundation. The last step is to determine the optimal safe area for evacuees in the inundation area. The work presented in this paper has emphasized timing issue in evacuation planning. A case study is given to illustrate the use of the approach

Metal-Embedded Graphene as Potential Counter Electrode for Dye-Sensitized Solar Cell

It is very important to explore a cheap but efficient catalyst as a counter electrode in a dye-sensitized solar cell (DSSC). In the present work, density functional theory (DFT) calculations were performed to investigate the reduction of triiodide ion catalyzed by a metal atom embedded in graphene. It is shown that the binding energy of a single Pt atom embedded into the divacancy of graphene (Pt@DV) is about −11.0 eV, larger than the location of Pt at single vacancy (Pt@SV). In the Pt@DV with a Pt loading of 25 wt %, the adsorption energy of the iodine atom and the dissociation energy of the iodine anion are respectively −1.54 and 0.60 eV, indicating a potential high catalytic activity of Pt–graphene. Further investigations of diverse transition-metal-embedded graphenes ranging from Sc to Zn imply that the Co-embedded graphene (in divacancy) may be a good candidate to be utilized as counter electrode in DSSC

Silver-Catalyzed Cascade Reaction of β‑Enaminones and Isocyanoacetates To Construct Functionalized Pyrroles

An unexpected silver-catalyzed cascade reaction of β-enaminones and isocyanoacetates affording functionalized pyrrole derivatives is reported. In this reaction, tautomeric equilibria of β-enaminones are utilized to generate imine partners in situ. A hypothesized sequential Mannich addition/cyclization of imine tautomers and isocyanoacetates followed by an unprecedented ring-opening of the resultant 2-imidazolines and dehydration–condensation deliver the final 1,2,4,5-tetrasubstituted pyrrole products
