Robust Laser‐Induced Graphene‐Boron‐Doped Diamond Nanowall Hybrid Nanostructures with Enhanced Field Electron Emission Performance for Microplasma Illumination Devices

open access: yesSmall Science, Volume 5, Issue 6, June 2025.
A facile procedure is developed for creating laser‐induced graphene (LIG)‐boron‐doped diamond nanowall (BDNW) nanostructures on flexible polyimide films. Although BDNW incorporation has resulted to increased defect density in the LIG, the obtained nanostructures benefit from enhanced electrical conductivity and specific surface area.

Disentangling Timing Uncertainty of Event‐Driven Connectedness Among Oil‐Based Energy Commodities

open access: yesAustralian Economic Review, Volume 58, Issue 2, Page 65-90, June 2025.
Abstract Reported news events frequently influence the pricing dynamics of oil‐based commodities. We analyse almost 900 oil‐related events from 1987 to 2022, categorising them based on recurring characteristics. We quantify dynamic connectedness among energy commodities and apply a novel bootstrap‐after‐bootstrap testing procedure to identify 21 ...
