Spin‐Split Edge States in Metal‐Supported Graphene Nanoislands Obtained by CVD
Advanced Materials, EarlyView.Combining STM measurements and ab‐initio calculations, we show that zig‐zag edges in graphene nanoislands grown on Ni(111) by CVD retrieve their spin‐polarized edge states after intercalation of a few monolayers of Au. ABSTRACT Spin‐split states localized on zigzag edges have been predicted for different free‐standing graphene nanostructures.

k-perfect geodominating sets in graphs [PDF]
Opuscula Mathematica, 2007 A perfect geodominating set in a graph \(G\) is a geodominating set \(S\) such that any vertex \(v \in V(G)\setminus S\) is geodominated by exactly one pair of vertices of \(S\).

Advanced Materials Technologies, EarlyView.This study demonstrates a cost‐effective hybrid nanofiller approach for developing conductive polyamide 6 filaments via melt spinning. Branched carbon nanotubes combined with carbon black create synergistic networks where spherical CB particles bridge aligned CNTs, maintaining electrical pathways during fiber drawing.

A characterization of star-perfect graphs
AKCE International Journal of Graphs and CombinatoricsMotivated by Berge perfect graphs, we define star-perfect graphs and characterize them. For a finite simple graph G(V, E), let [Formula: see text] denote the minimum number of induced stars contained in G such that the union of their vertex sets is V(G),

Advanced Materials Technologies, EarlyView.Modeling the blood–brain tumor barrier is challenging due to complex interactions between brain microvasculature and glioma cells. We present two‐photon polymerized 3D micro‐porous capillary‐like structures that support endothelial alignment, cytoskeletal organization, and pericyte‐endothelial‐glioma tri‐cultures.

Advanced Photonics Research, EarlyView.A Ge2Sb2Te5 (GST)‐based microring resonator is designed and simulated on a ZnSe‐platform that operates in the long‐wave infrared (LWIR) wavelength of 8 μm. The structure demonstrates strong power confinement and high Q‐factor. GST resonator is used for gas and biosensing applications.

Sharp Diamond Needles for Single‐Photon Emission
Advanced Photonics Research, EarlyView.We study the morphological evolution of single‐crystal diamond needles oxidized at 650–700 °C. Electron microscopy and photoluminescence reveal temperature‐ and time‐dependent sharpening, length reduction, and surface modifications affecting tip properties.

Perfect 3-colorings of the cubic graphs of order 10
Electronic Journal of Graph Theory and Applications, 2017 Perfect coloring is a generalization of the notion of completely regular codes, given by Delsarte. A perfect m-coloring of a graph G with m colors is a partition of the vertex set of G into m parts A_1, A_2, ..., A_m such that, for all $ i,j \in \lbrace ...
