Are hemispherical caps of boron-nitride nanotubes possible?

, 2004
We report all-electron, density-functional calculations with large Gaussian polarization basis set of the recently synthesized octahedral B24N24 cage that is perfectly round by symmetry, and boron-nitride (BN) clusters that its existence might suggest ...

Biopolymer‐Templated Hierarchical 3D‐Structured Gold Nanoparticle/Graphene Oxide Hybrid Materials for Ultrasensitive Surface‐Enhanced Raman Scattering

Advanced Functional Materials, EarlyView.
A scalable bio‐templated approach using spray‐coating and thermal annealing fabricates cellulose nanofibril (CNF) films loaded with gold nanoparticles (Au NPs) and graphene oxide (GO) hybrids as Surface‐enhanced Raman scattering (SERS) substrates. The 3D CNF network ensures uniform Au NPs distribution, while annealing induces more hotspots, confirmed ...

Quantifying Spin Defect Density in hBN via Raman and Photoluminescence Analysis

Advanced Functional Materials, EarlyView.
An all‐optical method is presented for quantifying the density of boron vacancy spin defects in hexagonal boron nitride (hBN). By correlating Raman and photoluminescence signals with irradiation fluence, defect‐induced Raman modes are identified and established an relationship linking optical signatures to absolute defect densities. This enables direct
