Giant Circularly Polarized Luminescence Driven by Excited‐State Hybridization Between Molecular Emitters and Chiral Environments

Advanced Materials, EarlyView.
A fundamental chiroptical response amplification mechanism is revealed to massively enhance molecular helicene chiral emitters. The luminescent dissymmetry factor of the helicene emitter is amplified by 133 times through excited‐state hybridization with a polymeric chiral environment.

Canopy Venom: Proteomic Comparison among New World Arboreal Pit-Viper Venoms

Toxins, 2016
Central and South American pitvipers, belonging to the genera Bothrops and Bothriechis, have independently evolved arboreal tendencies. Little is known regarding the composition and activity of their venoms.

A Comparison of the Efficacy of Antivenoms and Varespladib against the In Vitro Pre-Synaptic Neurotoxicity of Thai and Javanese Russell’s Viper (Daboia spp.) Venoms

Toxins
The heterogeneity in venom composition and potency in disparate Eastern Russell’s viper (Daboia siamensis) populations has repercussions for the efficacy of antivenoms. This is particularly pronounced in geographical areas in which the venom of the local

Suramin inhibits the early effects of PLA(2) neurotoxins at mouse neuromuscular junctions: a twitch tension study [PDF]

, 2011
Several phospholipase A(2) (PLA(2)) neurotoxins from snake venoms can affect acetylcholine release at the neuromuscular junction. In isolated nerve-muscle preparations three distinct phases have been described for this phenomenon: An initial transient ...

TADF Host Engineering for Improved Pure Blue Matrix‐Free Hyperfluorescent OLEDs with Ultranarrow Emission

Advanced Optical Materials, EarlyView.
This work presents the development of efficient blue thermally activated delayed fluorescent (TADF) materials that perform well without doping, enabling simplified, matrix‐free hyperfluorescence (MFHF) OLEDs. When combined with encapsulated narrow‐band emitters, the TADF materials serve as effective hosts resulting in pure blue, ultranarrow emission ...

Graphene as Infrared and Electron Transparent Electrode Applied to the Design of Narrow Bandgap Nanocrystal‐Based Photodiode

Advanced Optical Materials, EarlyView.
The article explores the need for transparent conductive electrode in the context of nanocrystal based infrared photodetectors beyond traditional transparent conductive oxide and metallic grids. Use of such sensor for imaging where the diode is deposited on a read‐out integrated circuit raised the need for top transparent electrode.
