Advanced Materials, EarlyView.Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

Techniques for Interactive Graph Drawing
, 2002 There are two complementary approaches to graph drawing: algorithmic and interactive. By algorithmic graph drawing we mean the automatic placement of vertices and routing of edges using heuristics to improve understandability.

Drawing Graphs in Euler Diagrams [PDF]
, 2004 We describe a method for drawing graph-enhanced Euler diagrams using a three stage method. The first stage is to lay out the underlying Euler diagram using a multicriteria optimizing system. The second stage is to find suitable locations for nodes in the

POM‐Based Water Splitting Catalyst Under Acid Conditions Driven by Its Assembly on Carbon Nanotubes
Advanced Materials, EarlyView.A newly‐engineered POM‐based electrocatalyst incorporating non‐innocent counter cations exhibits fast kinetics for either the OER or HER under strongly acidic conditions (1 m H2SO4), depending on whether it is assembled on carbon nanotubes (1@CNT) or physically mixed with them (1/CNT). In water‐splitting tests using a two‐electrode setup, these systems

Application of Web Map of Coal Mine Based on SVG
Gong-kuang zidonghua, 2011 For problem of limitation of expansibility and compatibility of Web map because that application of Web map need use some tool provided by the third party to realize graph drawing, the paper proposed an application scheme of Web map of coal mine based on

Journal of Computational GeometryWe study a fundamental question from graph drawing: given a pair $(G,C)$ of a graph $G$ and a cycle $C$ in $G$ together with a simple polygon $P$ with equally many vertices as $C$, is there a straight-line drawing of $G$ inside $P$ which maps the $i$-th

Energetic Offset in Organic Solar Cells‐ Importance, Confusion and Outlook
Advanced Materials, EarlyView.Energetic offsets in organic solar cells (OSCs) remain a subject of debate due to measurement‐ and lab‐dependent discrepancies. This Perspective clarifies the physical origins of these variations and identifies temperature‐dependent electro‐optical methods as a reliable approach to obtain consistent offset values.

Various heuristic algorithms to minimise the two-page crossing numbers of graphs
Open Computer Science, 2015 We propose several new heuristics for the twopage book crossing problem, which are based on recent algorithms for the corresponding one-page problem. Especially, the neural network model for edge allocation is combined for the first time with various one-

Frequent Graph Discovery: Application to Line Drawing Document Images
ELCVIA Electronic Letters on Computer Vision and Image Analysis, 2005 In this paper a sequence of steps is applied to a graph representation of line drawings using concepts from data mining. This process finds frequent subgraphs and then association rules between these subgraphs.
