Industrial‐Grade Structural Coloration with Robust and Vivid TiON‐Based Structures
Advanced Optical Materials, EarlyView.This study presents TiON‐based Fabry–Perot cavities as a robust strategy for structural coloration. By substituting the metal top layer with TiON, the structures achieve vivid, tunable colors and resist oxidation, abrasion, and humidity. Long‐term testing demonstrates stable optical absorption and minimal chromatic drift, highlighting TiON's ...

PISOT NUMBERS AND CHROMATIC ZEROS
, 2014 In this article we show that Pisot numbers of even degree and their powers cannot be roots of chromatic polynomials. We also consider the family of smallest Pisot numbers of odd degree. We show that they cannot be roots of chromatic polynomials of connected graphs with a certain maximum number of vertices.

Structural Colors from Ultrathin Lignin Films
Advanced Optical Materials, EarlyView.Thickness‐dependent structural colors in ultrathin lignin films generate a full visible palette, tuned simply by solution concentration and spin speed. Abstract Structural colors offer a sustainable alternative to toxic pigments and dyes, yet their realization from lignin, the most abundant aromatic biopolymer, has remained elusive.

Chromatic Number Versus Cochromatic Number in Graphs with Bounded Clique Number
European Journal of Combinatorics, 1990 The cochromatic number \(z(G)\) of a graph \(G\) is the minimum number of sets into which the vertices of \(G\) can be partitioned so that each set is independent in \(G\) or induces a complete subgraph of \(G\). The present paper proves the existence ofa function \(f(n)\) with the following property: If \(G\) does not contain a complete \(n\)-graph ...

Spectral Peaked Optical Frequency Comb for Highly Sensitive Spectroscopy
Advanced Photonics Research, EarlyView.Optical frequency combs represent a breakthrough in metrology, and comb mode selection and power scaling are important issues for highly sensitive spectroscopy. This article reviews the development of a spectrally peaked optical frequency comb using the novel phenomenon of spectral peaking for highly sensitive spectroscopy.

On circulant chromatic number and circulant chromatic function
Discrete Mathematics, 2001 The circulant chromatic number (= star chromatic number, see \textit{A. Vince} [J. Graph Theory 12, No. 4, 551-559 (1988; Zbl 0658.05028)]) is accompanied with the new concept of a circulant chromatic function. Apart from basic facts and examples about this function the paper mainly investigates (in part with the help of this function) the relationship
