On the evolution of random discrete structures [PDF]

, 2000
In this thesis, we study the evolution of random discrete structures. Such evolution processes usually fit into the following general framework. Initially (say at time 0), we start with a very simple structure (e.g. a graph on n vertices with no edges) and a set of "building blocks'' (e.g. the set of edges of the complete graph on n vertices).

Construction of discrete structures, especially isomers

Discrete Applied Mathematics, 1996
The authors consider the problem of enumerating isomers with a given composition. Each isomer corresponds to a graph---the vertices of the graph correspond to the atoms, and the bounds to the linkages---valence 1 for carbon atoms, two for oxygen atoms, one for hydrogen atoms, etc.

Ionic Liquid‐Based Reversible Metal Electrodeposition for Adaptive Radiative Thermoregulation Under Extreme Environments

Advanced Functional Materials, EarlyView.
A wideband tunable electrochromic device with dynamic thermal emissivity control is demonstrated. The system enables adaptive heat regulation via electrochemically modulated silver deposition, achieving efficient cooling and heating states. The flexible design ensures mechanical robustness under bending conditions, making it promising for portable and ...

Unique Performance Considerations for Printable Organic Semiconductor and Perovskite Radiation Detectors: Toward Consensus on Best Practice Evaluation

Advanced Functional Materials, EarlyView.
A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

Ionic Metal Poly(heptazine Imides) and Single‐Atoms Interplay: Engineered Stability and Performance for Photocatalysis, Photoelectrocatalysis and Organic Synthesis

Advanced Functional Materials, EarlyView.
Poly(heptazine) imides (PHIs), a crystalline carbon nitride subclass, intercalate metals to deliver high stability, tunable electronics, and efficient charge separation. These features enable solar‐driven applications such as hydrogen evolution, CO₂ reduction, and organic synthesis.

NEW THIO S2- ADDUCTS WITH ANTIMONY (III AND V) HALIDE: SYNTHESIS AND INFRARED STUDY

Scientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2013
Five new S2- adducts with SbIII and SbV halides have been synthesized and studied by infrared. Discrete structures have been suggested, the environment around the antimony being tetrahedral, trigonal bipyramidal or octahedral.
