Optical excitations in hexagonal nanonetwork materials [PDF]
Journal of Experimental and Theoretical Physics, 2002 Optical excitations in hexagonal nanonetwork materials, for example, Boron-Nitride (BN) sheets and nanotubes, are investigated theoretically. The bonding of BN systems is positively polarized at the B site, and is negatively polarized at the N site. There is a permanent electric dipole moment along the BN bond, whose direction is from the B site to the

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Lithium–sulfur (Li–S) batteries are promising for next‐generation high‐energy‐storage systems but are hindered by polysulfide shuttle, sluggish kinetics, and volume expansion. Conventional carbon hosts struggle to simultaneously anchor and convert polysulfides efficiently.

Template‐Assisted 3D‐PVDF Nanonetworks for Passive Daytime Radiative Cooling
Nanophotonics, Volume 15, Issue 13, 13 July 2026.Three‐dimensional polyvinylidene fluoride (3D‐PVDF) nanostructures were fabricated by infiltrating the polymer into 3D anodic aluminum oxide (3D‐AAO) templates. Due to their high solar reflectance (82.4%) and infrared emissivity (96.7% between 8 and 13 µm), they are an ideal candidate for radiative cooling.
