Multiwavelength Optical Pulse-Induced Temporal State Mapping in an ITO/SnO2/ITO Optoelectronic Synaptic Device

A vertical ITO/SnO2/ITO optoelectronic synaptic device was fabricated by magnetron sputtering for optical sensing and temporal-state encoding. The ITO/SnO2 stack exhibited 88.3% average transmittance over 400–800 nm. The device responded to 380, 550 and 660 nm illumination and sh...

Cove-edge-induced vibrational confinement and weakened collective phonon transport in graphene nanoribbons

Periodic cove edges alter heat conduction in graphene nanoribbons in ways that are not fully captured by geometric boundary scattering. We investigate this effect using a graphene-nanoribbon-specific neuroevolution potential together with molecular dynamics, phonon Monte Carlo si...

γ-Aminobutyric Acid Alleviates Discoloration of Or Mutant Cauliflower via BoMYB24-Mediated Transcriptional Regulation of BoLCYB

Abstract Orange (Or) mutant cauliflower is prone to discoloration during storage, which affects its commercial value. γ-Aminobutyric acid (GABA) treatment can effectively delay the discoloration of Or mutant cauliflower during storage; however, its mechanism of action remains unc...

Discovery of Three Macrocyclic Diterpenoid Skeletons from Croton laevigatus and Their NF-κB Inhibitory Activity
