Researchers Design 3D Photonic Crystals for Targeted Photon Density of States in ssalimpour

Researchers used spatiotemporal terahertz emission nanoscopy to map the electromagnetic signatures of ultrafast spin-driven charge currents in a fiber-coupled spintronic terahertz emitter with femtosecond temporal resolution and nanoscale spatial sensitivity. The study shows how localized in-plane currents produce detectable out-of-plane electric fields, clarifying how near-field terahertz measurements can probe ultrafast spin-to-charge transport. 10/14/2026

A systematic review of 25 studies found that green-synthesized nanoparticles can improve the antimicrobial and mechanical performance of glass ionomer cements, and some formulations also support fluoride release. The evidence came from 24 laboratory studies and one animal study, with no human clinical trials, so long-term safety and clinical effectiveness remain uncertain. 10/13/2026

Researchers developed an end-to-end inverse design method that uses LSTM prediction, a conditional generative adversarial network, and metasurface reconstruction to tailor the photon density of states in 3D photonic crystals made through holographic lithography. The method produced connected structures with strong local pDOS enhancement across multiple target frequencies and identified two recurring high-pDOS morphological families, while the reported optical gains remained computational rather than experimentally measured. 10/12/2026
