HYPER-WIENER INDEX OF ZIGZAG POLYHEX NANOTUBES [PDF]
The ANZIAM Journal, 2008 Abstract The hyper-Wiener index of a connected graph G is defined as $WW(G)=(1/4)\sum _{(u,v)\in V(G)\times V(G)}\big (d(u,v)+d(u,v)^2\big )$ , where V (G) is the set of all vertices of G and d(u,v) is the distance between the vertices u,v∈V (G).

Advanced Materials Interfaces, EarlyView.Using femtosecond ablation, we show that an ordered, stoichiometric crystalline PdSe2 target can be controllably converted into a stable, disordered, non‐stoichiometric, and highly functional amorphous nanomaterial, PdSe2−x${\rm PdSe}_{2-x}$. The obtained nanoparticles offer significant advantages over conventional planar plasmon‐free substrates due to

Mechanistic Origin of Photodegradation and Impurity Effects in Donor–Acceptor Luminescent Radicals
Advanced Optical Materials, EarlyView.Purification‐dependent impurities distort the apparent optical and analytical data of TTM‐based radicals without altering their intrinsic photophysical properties. Carbazole attachment elevates the activation barrier of the photodegradation pathway, offering design principles for achieving more robust luminescent radical materials.

Advanced Photonics Research, EarlyView.This review highlights recent advances in accelerating luminescence in nanostructures through cooperative emission, resonator coupling, and nonlocal light–matter interactions. By unifying concepts such as excitonic superradiance, superfluorescence, and the plasmonic Purcell effect, it reveals physical limits of ultrafast emission and their potential ...

Midbrain PAG Astrocytes Modulate Mouse Defensive and Panic‐Like Behaviors
Advanced Science, EarlyView.Astrocytes in the midbrain periaqueductal gray (PAG) dynamically encode threat intensity and shape defensive action selection in mice. Real‐time Ca2+ imaging reveals robust astrocytic activation during predator odor and CO2 exposure. Aberrant astrocytic Ca2+ overactivation disrupts goal‐directed escape, biases behavior toward freezing, and induces ...

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.

Helix Alignment, Chevrons, and Edge Dislocations in Twist‐Bend Ferroelectric Nematics
Advanced Science, EarlyView.The recently discovered twist‐bend ferroelectric nematic (NTBF) is the new member of the multiferroic family, representing a fluid with an oblique helicoidal (heliconical) periodic structure of spontaneous electric polarization. The work presents a thorough exploration of the material properties of this phase, how the periodic modulation of ...
