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.

Nanoscale Mapping of the Subcellular Glycosylation Landscape
Advanced Science, EarlyView.Using multiplexed super‐resolution imaging with fluorophore‐labeled lectins, this study reports intracellular glycosylation at the nanoscale across organelles and synaptic specializations. Extending glycan analysis beyond the cell surface, Glyco‐STORM reveals distinct glycosylation nanodomains in the ER, Golgi, lysosomes, and synaptic sites.

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 ...

A Degradable Bioinspired Flier with Aerogel‐Based Colorimetric Sensors for Environmental Monitoring
Advanced Science, EarlyView.Biodegradable fliers are developed inspired by Tipuana tipu samaras, integrating cellulose nanocrystal aerogel (CNCa) sensors loaded with natural dyes for pH and ammonia detection. The lightweight, degradable fliers mimic natural morphology and aerodynamics, offering an eco‐friendly, scalable solution for in situ environmental monitoring after passive ...

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
