Advanced Functional Materials, EarlyView.Wood‐based broadband blackbody is achieved by reconfiguration of wood with lignin nanoparticles prior carbonization. Neglectable reflectivity from the visible to infrared wavelengths is obtained by combining thin nanostructures originated from the wood cell walls with long‐range microcavities in the wood lumina.

Near‐Field Optical Detection of Defect‐Stabilized Metallic Islands at the Verwey Transition in Fe3O4
Advanced Functional Materials, EarlyView.Nanoscale metallic islands emerging across the Verwey transition in thin films of Fe3O4 are imaged using near‐field optical microscopy from mid‐infrared to terahertz frequencies. Recurring across thermal cycles, these disorder‐stabilized islands exhibit distinct transition temperatures.

Invasion percolation and global optimization
, 1996 Invasion bond percolation (IBP) is mapped exactly into Prim's algorithm for finding the shortest spanning tree of a weighted random graph. Exploring this mapping, which is valid for arbitrary dimensions and lattices, we introduce a new IBP model that ...

Asymptotic Enumeration of Spanning Trees [PDF]
Combinatorics, Probability and Computing, 2005 We give new formulas for the asymptotics of the number of spanning trees of a large graph. A special case answers a question of McKay [Europ. J. Combin. 4 149–160] for regular graphs. The general answer involves a quantity for infinite graphs that we call ‘tree entropy’, which we show is a logarithm of a normalized determinant of the graph Laplacian ...
