Active Photonic Platforms XIII.
Optical phase change materials (PCMs) are a unique class of materials which exhibit extraordinarily large optical property change (e.g. refractive index change > 1) when undergoing a solid-state phase transition, and they have witnessed increasing ad

We report an electrically reconfigurable metasurface platform based on optical phase change materials. Multi-cycle reversible switching is realized using conductive micro-heaters. Large-contrast spectral tuning and beam-steering are demonstrated.

We report on pixelated, reversibly-switchable devices based on novel chalcogenide phase change materials (PCMs), Ge-Sb-Se-Te (GSST) with transparency from 1.5 to > 15 microns. We describe applications in integrated photonics and hyperspectral imaging

TAR RNA-binding protein TRBP was originally isolated by its binding affinity for radiolabeled HIV-1 leader RNA. Subsequent studies have suggested that this protein is one member of a family of double-stranded RNA-binding proteins. Recent findings ind

A 'G-less' cassette was cloned downstream of the human immunodeficiency virus type 1 (HIV-1) long terminal repeat (LTR) to facilitate rapid identification of authentic LTR-directed transcription in T cell nuclear extracts. Despite a high constitutive
