Explore the device hypergraph

#Open the device hypergraph

Open Resources → Device Database and select the hypergraph view in the sidebar. It shows relationships among materials, structures, process methods, solvents, antisolvents and additives found in papers.

The graph contains entity nodes and hyperedges. Device-structure hyperedges group a device's structural relationships; layer-process hyperedges group the process-related elements of a layer.

#Choose a direction and paper count

1. Select the device direction.
2. Adjust the paper count, starting with a smaller scope to understand the graph.
3. Refresh the graph and inspect the node, hyperedge and paper counts.

The paper counter indicates the loaded sample and available total. The graph represents that loaded scope. An absent relationship does not establish that it is absent from the database.

#Read the complete hypergraph

The complete-hypergraph view is currently available. It expands entities and hyperedges for the selected scope without requiring a central material. Views marked as coming soon are not yet available.

Use the legend to identify node categories. Zoom into a dense area to read labels; labels may be hidden at smaller scales to preserve the overall view.

Switch between force-directed and hierarchical layouts. Fit the graph to recover the overview, open full screen for more space, or use settings to adjust its presentation.

#Save a graph image

1. Confirm the device direction and paper count, refresh the graph and wait for loading to finish.
2. Adjust the layout, zoom and displayed scope so the relevant nodes and relationships are readable.
3. Open More actions in the graph toolbar. Choose Download screenshot for a PNG or Export SVG for a vector image.
4. Record the query date, device direction, paper count and relevant nodes or relationships alongside the image.

A screenshot preserves the current view; SVG is useful for scaling and page layout. Both save a graph presentation rather than complete database records. Export again after changing the layout or displayed scope, and retain paper references and source evidence separately.

#Follow relationships back to evidence

Select a node and use the available node-details action to inspect it. Follow relationships to related materials, processes and paper references.

Co-occurrence means elements appear together in the relevant papers or processes. To assess an additive's effect on performance, return to device details and the paper to inspect controls and test conditions.
